Many people think of Fiat as just an economy car maker. The truth is Fiat is a multi-faceted company with core businesses that focus on the automotive industry. The Fiat Group is made up of nine companies. One of them is the the legendary Ferrari company.
Ferrari has been owned by Fiat for the past 40 years. During this time there has been a wide range of cars produced by the Maranello based firm. Each one has been unique, beautiful and a technical masterpiece. However, with the new 458 Italia, Ferrari has pushed the limits of technology and passion. This automotive tour de force in design and engineering has been given the name Italia to honor the classic Italian tradition of advanced design and engineering.
These achievements, which have spanned centuries, make up the Italian DNA and are what fuel Ferrari and Fiat to produce their award winning designs.
People may pose the question of what Ferrari cars have to do with Fiat cars, but anyone who knows the history of the Fiat company knows the links the two companies have. For example, Aurelio Lampredi, the famed Ferrari engine designer of the 1950's (who designed many Ferrari racing engines), went on to Fiat and designed a slew of Fiat engines. These engines include the original Fiat 500's 2 cylinder engine as well as the legendary Fiat Twin Cam engine (the first affordable Twin Cam engine and the prototype for all belt driven twin cam engines used today).
Although Ferrari is said to be run autonomously in the Fiat empire (the President of Ferrari, Luca Cordero di Montezemolo is also the Chairman of Fiat), technology is shared between the companies.
For example, the Dualogic/MTA (Manual Transmission Automated) gearbox technology is derived directly from the Ferrari 355 F1 system.
Also, engineer Paolo Martinelli, head of Scuderia Ferrari's Engine Department from 1994 to 2006 (who was responsible for developing the Ferrari V10 Formula One engines that won 6 constructor championships) and currently head of the Petrol Engine Development division at Fiat Powertrain Technology , oversaw the making of the 1.4L 16V Turbo engine used in the new Fiat 500 Abarth.
And, of course, The Abarth 695 "Tributo Ferrari", a collaboration between Abarth and Ferrari, resulting in an increase in horsepower from the standard Abarth's 135hp to the Tributo's 180hp.
With this, we can see the link between Fiat and Ferrari will be a good thing for American car enthusiasts.
Below is an overview and videos of the Ferrari 458 Italia for you to enjoy. Clearly Italian DNA has served Ferrari very well!
ITALIA - Ferrari’s innovative new V8
The 458 Italia, the latest incarnation of the mid-rear engined berlinetta
was unveiled at the Frankfurt Motor Show during September, 2009. While it’s true that every Ferrari is innovative by definition, it’s equally true that in the course of the Prancing Horse’s history, certain cars have marked a genuine departure from the current range. This is very much the case with the Ferrari 458 Italia, which is a massive leap forward from the company’s previous mid engined sports cars.
The new model is a synthesis of style, creative flair, passion and cutting-edge technology, characteristics for which Italy as a nation is well-known. For this reason Ferrari chose to add the name of its homeland to the traditional figure representing the displacement and number of cylinders.
The Ferrari 458 Italia is a completely new car from every point of view: engine, design, aerodynamics, handling, instrumentation and ergonomics, just to name a few.
A two-seater berlinetta, the Ferrari 458 Italia, as is now traditional for all Ferrari’s road going cars, benefits hugely from the company’s Formula 1 experience. This is particularly evident in the speed and precision with which the car responds to driver inputs and in the attention focused on reducing internal friction in the engine for lower fuel consumption than the F430, despite the fact that both overall displacement and power have increased. However, Ferrari’s track experience makes its presence felt in the 458 Italia not only in terms of pure technological transfer but also on a more emotional level, because of the strong emphasis on creating an almost symbiotic relationship between driver and car. The 458 Italia features an innovative driving environment with a new kind of steering wheel and dashboard that is the direct result of racing practice. Once again input from Michael Schumacher - who was involved from the very start of the 458 Italia project - played an invaluable part.
The Ferrari 458 Italia’s Pininfarina design provides further evidence of the complete
departure from the past that this new car hails. The Ferrari 458 Italia has a compact, aerodynamic shape, underscoring the concepts of simplicity, efficiency and lightness that inspired the project. As with every Ferrari, the car’s styling has been very heavily influenced by the requirements for aerodynamic efficiency, as can be seen from the downforce of 140 kg at 200km/h generated by the new model. The front features a single opening for the front grille and side air intakes, with aerodynamic sections and profiles designed to direct air to the coolant radiators and the new flat underbody. The nose also sports small aeroelastic winglets which generate down force and, as speed rises, deform to reduce the section of the radiator inlets and cut drag.
The new 4499 cc V8 is the first Ferrari direct injection engine to be mid-rear mounted. It has a very low piston compression height typical of racing engines which contributed to achieving its compression ratio of 12.5:1. Equipped with the traditional flat-plane crankshaft, the engine delivers 570 CV at 9000 rpm and, with an outstanding power output of 127 CV/liter, sets a new benchmark not only for the whole Ferrari range and the history of company, but also for the entire market segment. Maximum torque is 540 Nm at 6000 rpm, over 80 per cent of which is available from 3250 rpm. Specific torque is a record 120 Nm/liter. However, what is truly extraordinary is the amount of torque available while still maintaining high levels of power at low revs.
The car’s soundtrack is also typical Ferrari, with an exciting, powerful growl emerging from the engine before it channels through to the exhaust’s three rear tailpipes.
The 458 Italia is equipped with the seven-speed dual-clutch transmission which increases performance whilst providing very smooth shifts even at full throttle. The engineers have developed specific, sportier gear ratios to match the power and torque curves of the new V8, guaranteeing high torque even at lower engine speeds and allowing the car to reach its maximum speed in top gear.
This new Ferrari is also a major leap forward when it comes to cutting emissions. Despite the fact that the new engine is significantly more powerful than the V8s that preceded it, the Ferrari 458 Italia produces just 320 g/km of CO2 and fuel consumption is 13.7 l/100 km (combined cycle), the best in the entire segment.
The engineers also focused on weight reduction during the design phase for similar reasons. Consequently, the Ferrari 458 Italia has a dry weight of 1380 kg with a power to-weight ratio of 2.42 kg/CV. Weight distribution is also optimal with 58 per cent over the rear axle. The result of the engineers’ endeavors can be summed up in to two simple statistics which together perfectly encapsulate the Ferrari 458 Italia’s exceptional performance: 0-100 km/h acceleration in under 3.4 seconds and a maximum speed in excess of 325 km/h.
For the new chassis, once more in aluminum, Maranello’s engineers incorporated various types of advanced alloys along with aerospace industry-derived manufacturing and bonding techniques.
With regard to vehicle dynamics, the Ferrari 458 Italia’s suspension features twin wishbones at the front and a multi-link set-up at the rear tuned for maximum road holding and superlative handling. Along with a more direct steering ratio, the 458 Italia thus offers extremely rapid turn-in and body control whilst maintaining superior ride comfort.
The integration of the E-Diff and F1-Trac (now controlled by the same ECU) and their respective mappings is even greater, resulting in a 32 per cent increase in longitudinal acceleration out of corners compared to previous models. The evolution of the control logic, with even faster and more accurate calculation of levels of grip, ensures even greater road holding, better handling and ease of control on the limit.
The same ECU also governs the high-performance ABS, providing even more precise control over the logic threshold and greater efficiency. The brakes also feature a prefill function whereby the pistons in the calipers move the pads into contact with the discs on lift off to minimize delay in the brakes being applied. This combined with the ABS has cut the 100-0 km/h braking distance to a mere 32.5 meters.
The Ferrari 458 Italia’s interior is another area of the car that exalts its sporty personality. The driver is welcomed by a new layout and a revolutionary ergonomic interface where the main controls are all clustered on the steering wheel.
With the Ferrari 458 Italia, Maranello has brought a highly distinctive new car to its 8-cylinder range. The company now offers two models that share a common, race derived DNA, both exceptionally sporty and fun to drive in true Ferrari tradition, but aimed at two very different kinds of client. While the Ferrari California was created for owners requiring a more versatile sports car with a practical edge, the 458 Italia is designed for owners for whom the priority is uncompromising on-road performance with occasional track day capability, but who still demand a car that is usable in day-to-day driving like all Ferrari’s recent models.

Fiat has decided to produce the Fiat 500's MultiAir engine at the Chrysler Dundee, Michigan engine plant (GEMA). It beats out the Saltillo, Mexico engine plant that was also in the running to manufacture this engine. Saltillo is near the Toluca, Mexico plant that produces the 500.
GEMA, which stands for Global Engine Manufacturing Alliance LLC, was a manufacturing arm of Global Engine Alliance LLC. The alliance was a joint venture of Chrysler, Mitsubishi Motors, and Hyundai Motor Company for developing a line of shared engines. On August 31, 2009, Chrysler bought out the two partners and the engine facility is now a wholly-owned subsidiary of Chrysler Group LLC.
Fiat will invest $179 million at Dundee to produce the MultiAir engine, bringing an estimated 155 new employees to Chrysler. To help bring this investment about, the Michigan Economic Growth Authority Board in November approved a $4.6 million, 10-year tax credit for Chrysler.
Another reason for choosing Dundee over the Saltillo plant was the stipulation in the original Chrysler/Fiat alliance that in order to increase its stake in Chrysler, Fiat would have to produce this engine here in the USA.
Below is an excerpt of the official Fiat/Chrysler agreement:
"...Fiat will have right to receive up to an additional 15% equity interest (by vote and value) on a fully diluted basis. This stake can be obtained in three tranches of 5% each subject to the achievement of predetermined targets, in particular, achievement of regulatory approvals to produce the FIRE family of engines in the USA; achievement of sales of Chrysler vehicles outside NAFTA, and achievement of regulatory approval to produce a Chrysler model based on Fiat technology. Upon obtainment of such additional 15% interest, Fiat will also have the right to appoint another director of Chrysler..."
The following is the official Chrysler press release on this investment:
Chrysler Group LLC to Invest $179 Million in Jobs for Michigan, Fuel Efficient Engines for North America
Company Is Delivering on the Promise of the Fiat-Chrysler Strategic Alliance, says Chrysler Group CEO Marchionne
A Significant Step to Grow and Diversify State’s Economy, says Michigan Governor Granholm
Auburn Hills, Mich., Dec 17, 2009 - Chrysler Group LLC will invest $179 million to launch production of an advanced technology, fuel-efficient engine for the North American market, which will be built at the company’s Global Engine Manufacturing Alliance (GEMA) plant in Michigan.
The investment will create up to 573 new jobs industry-wide, including up to 155 new Chrysler Group jobs.
The GEMA plant, located in Dundee, Michigan, will produce the 1.4-liter, 16-valve Fully Integrated Robotized Engine (FIRE) for use in Chrysler Group’s growing fleet of fuel-efficient vehicles. FIRE is a collaboration between Chrysler Group and Fiat powertrain groups and will include Fiat’s innovative advanced technologies to reduce engine emissions and improve fuel economy.
“This is one more important step forward that demonstrates our intent to deliver on the promise of the Fiat-Chrysler strategic alliance and the substance of the road map we laid out in November,” said Sergio Marchionne, Chrysler Group LLC Chief Executive Officer.
“This project further demonstrates that Michigan has the competitive business climate, infrastructure and talented workforce to compete in the global marketplace,” said Governor Jennifer M. Granholm.
"We are pleased and excited with the I-4 FIRE engine loading at GEMA. The UAW is committed to working with the Company to continue doing everything we can to ensure this new engine launch is successful." said General Holiefield, Vice President and Director of the UAW, Chrysler Department.
Today’s announcement follows a thorough site selection review by the company and actions by the Michigan Economic Development Corporation and the Village of Dundee in support of the project.
Production of the 1.4-liter engine at GEMA will begin in the fourth quarter of 2010. The first application of the engine will be in the North American-built Fiat 500 that will go into production in 2011.
Chrysler Group has two plants at the GEMA complex, located at 5800 North Ann Arbor Road outside Dundee. In addition to the South plant which will produce the FIRE, the North Plant, opened in October 2005, produces the World Gas Engine, Chrysler Powertrain’s naturally-aspirated, four-cylinder engine family.
Chrysler Group LLC Introduces Fiat’s 1.4-liter, In-line 4-cylinder, Fully Integrated Robotized Engine with Multiair Technology to Powertrain Lineup
Inside Fiat's MultiAir engine
Auburn Hills, Mich., Dec 17, 2009 - Chrysler Group LLC will debut Fiat’s 1.4-liter, in-line four-cylinder Fully Integrated Robitized Engine (FIRE) featuring Multiair in the Fiat 500 starting in 2010. The engine, well-suited for a small car application, delivers 100 horsepower (75 kW) at 6,750 rpm and 95 lb.-ft. (129 N•m) of torque at 4,250 rpm. A turbo version also will be available in future applications. The 1.4-liter FIRE features Fiat’s Multiair technology, which significantly reduces emissions while improving fuel economy and power delivery.
The 1.4-liter FIRE features four valves per cylinder and incorporates state-of-the-art technology for Fully Variable Valve Actuation (FVVA), also known as MultiAir. Multiair is a sophisticated technology that delivers an increase in power up to 10 percent and a reduction in fuel consumption and emissions up to 10 percent when compared to similar engines. A turbo version of the engine is also planned and will produce a fuel economy improvement up to 25 percent when compared to a V-6 engine with equivalent power.
The MultiAir system consists of electro-hydraulic variable valve actuators filled with conventional oil, which is interposed between the camshaft and each valve. A solenoid valve is energized every 360-degree camshaft rotation, regulating the quantity of oil addressed to the actuator or to a reservoir. The lift of the valve is a function of the quantity of oil addressed to the actuator, ranging from full lift to complete valve closure. Each solenoid valve may also delay application of the actuator in advance, leading to late valve opening or early valve closing.
MultiAir is exclusive for Chrysler Group in North America and is based on a series of Fiat Powertrain patents related to hardware, combustion strategies and controls that allow for full control of the lift and timing of engine valves.
In the early 1970s, robotics in assembly plants was not common. The term “FIRE” came into existence when Fiat integrated the use of robotics in the production process of manufacturing plants. Although mechanized assembly is commonplace today, the brand name FIRE has remained with Fiat’s powertrain lineup.
Chrysler's new Pentastar V6
The 1.4-liter FIRE with Multiair is the world's first mass production engine to incorporate such technology to control the intake valves. Dedicated components have been developed to accommodate four "bricks" (one for each cylinder), which package relevant components. MultiAir technology can be adapted to different types of engines, including Diesels for enhanced NOx control, and is planned for Chrysler Powertrain's four-cylinder World Gas Engine and all-new Pentastar V-6.

Alfa Romeo has released pictures of their new Giulietta sedan. The Giulietta is the first Fiat Group Auto that uses the C-Evo chassis. C-Evo is the evolution of Fiat's compact chassis currently used in the Fiat Bravo. This chassis (or platform architecture) is one of the technologies being given to Chrysler and is said to save Chrysler at least $1 billion in developmental costs.
Fiat spent an estimated $148 million (100 Million Euros) upgrading and revising the current compact chassis with a new, advanced McPherson strut front and multilink rear suspension, lengthening the wheelbase and cutting the overhangs front and rear. In addition, Fiat has increased the chassis stiffness and also increased the crash worthiness (the current Bravo is already know for its five star crash rating and is listed at the top of its category by NCAP, Europe's leader in crash testing assessment).
Another advantage with this platform is it utilizes space frame technology, this allows its wheelbase to be easily adjusted to meet various models specifications.
Dodge 2010-2014 product plans (click to enlarge)
For example, in the compact segment, this chassis is being used for the replacement for the Dodge Caliber, which is due out in 2012. In the mid-size segment, the replacements for the Dodge Avenger and Chrysler Sebring will come out utilizing the C-Evo chassis, but with a longer wheelbase, this mid-size chassis is called the D-Evo, and is due out in 2013.
An added plus with the C-Evo is that besides front wheel drive, the chassis offers all wheel drive capabilities, opening up a new market for Chrysler in the compact and mid-size market segments.
The Alfa Romeo Giulietta will premier during the 2010 Geneva Motor Show, held from March 4- 14. Below is the Alfa Romeo press release on the new Giulietta:
Alfa Romeo Giulietta: world preview
The New 2010 Alfa Romeo Giulietta
The new Alfa Romeo Giulietta will be presented to the world at the forthcoming Geneva Car Show. Sales of the new model will start in spring and be gradually extended to all the major markets. The Alfa Romeo Giulietta is expected to give new impetus to the brand in one of Europe's most important segments.
In the Centenary year, the name is a tribute to an automobile myth and Alfa Romeo.
The Giulietta is a car that, in the fifties, caught the imagination of generations of car enthusiasts, making the dream of owning an Alfa Romeo and enjoying the high level of comfort and technical excellence accessible for the first time.
The Alfa Romeo Style Centre has produced a new Giulietta, a sports car capable of expressing both great agility on the most demanding routes and providing comfort on everyday roads.
A new architecture for enhancing road hold and agility in total comfort and safety
Meet the new Alfa Romeo, a compact created to appeal to customers who seek top dynamic performance and those who are looking for a distinctive style and a high level of comfort.
The Giulietta has brand-new architecture, designed to meet the expectations of the most demanding customers in terms of road holding, agility and safety. Its excellent dynamic performance and great comfort are the result of refined technical solutions implemented in the suspensions, a next-generation steering system, a rigid yet light structure made of aluminum and high-strength steel, and state-of-the-art manufacturing technologies.
Alfa DNA, a device which customizes behavior of the car according to different driving styles and road conditions, can adapt the new Alfa Romeo to the needs of each individual driver to enhance driving pleasure and comfort. The new architecture of the Alfa Giulietta was designed to integrate and enhance all on board systems. Three set-ups (Dynamic, Normal and All Weather) are available and can be selected using the Alfa DNA. This device - standard across the entire range of the new model - modifies the operating parameters of the engine, of the steering system, and of the Q2 electronic differential, in addition to fine-tuning the stability control system (VDC) behavioral logics.
Italian style sportiness and comfort
The Alfa Romeo 8C Competizione Concept Car
Combining sportiness and elegance, the Alfa Giulietta is the result of Alfa Romeo's new direction in style and technology - an approach that started with the 8C Competizione super car and which recalls the brand's glorious past while projecting its traditional values of technology and emotion into the future.
The front end is developed around a “trilobe shape” and features a brand-new interpretation of the classic Alfa grille, set into the front bumper and suspended between the two air intakes. The entire car develops from here to combine a lively personality with an elegant form.
The front headlamps implement LED technology and a Daytime Running Lights (DRL) function for maximum active safety.
The profile of the Alfa Romeo Giulietta is rich in personality and confers the appearance of an agile, solid model. This is above all the result of the coupé shaped side windows, which highlight dynamic and streamlined shape, and of the concealed rear handles. The side ribbing adds to the car's slender look, while the taut lines closing in on the rear end accentuate the "wedge" shape of the body.
The style of the rear end, like that of the front and the side, is strong and consolidates the impression of a muscular car, firmly gripped to the road.
Like the headlamps, the rear light clusters implement LED technology, to the advantage of preventive safety, in addition to good looks.
The interior design is taut and light: a horizontally developed dashboard with aluminum element accents and rocker controls which explicitly recall the 8C Competizione. Painstaking attention to detail and the high quality of the materials used are the most advanced expression of Italian style.
Finally, the dimensions of the new car give a compact, dynamic shape combined with excellent roominess and a capacious boot (350 liters): the car is 4.35 meters long, 1.46 meters high and 1.80 meters wide with a wheelbase of 2.63 meters.
Innovative engines for exciting, environmentally friendly driving
The Alfa Romeo Giulietta guarantees top level performance and next-generation technology in terms of technical solutions, performance and environmental friendliness. Four Turbo engines will be available at launch, all Euro 5 compliant and fitted with a standard “Start&Stop” system for reducing consumption and emissions: two petrol engines (1.4TB - 120 HP and 1.4TB MultiAir - 170 HP) and two diesel engines (1.6 JTDM - 105 HP and 2.0 JTDM - 170 HP, both belonging to the second generation of JTDM engines). Finally, the range is completed with the lively 1750 TBi - 235 HP with an exclusive Quadrifoglio Verde configuration.
Safety and dynamic behavior at the top of the segment
Alfa Romeo Giulietta was designed to obtain the maximum Euro NCAP rating in order to offer total protection to driver and passengers. Furthermore, suspension, steering and braking system are designed to be perfectly balanced even during extreme maneuvers.
Finally, the Alfa Romeo Giulietta is fitted with the most sophisticated electronic devices for dynamic control as standard: VDC (Vehicle Dynamic Control), DST (Dynamic Steering Torque), Q2 electronic differential and Alfa DNA selector. All these systems guarantee driving safety, dynamism and performance in the best Alfa Romeo tradition.

MultiJet II, Fiat's new innovation in diesel engine technology (you can read a description here) is making its debut in the Fiat 500 and 500C (the cabriolet version of the normal 500). MultiJet II is one of the technologies that Fiat is sharing with Chrysler and it could change how Americans perceive diesel engines and prefer what type of engine equips their car.
Below is a comparison of the specifications on all the available engines in the Fiat 500 range. First up is the new MultiJet II 1.3L :
New 1.3L 16V MultiJet II Turbo diesel
95hp @ 4000 rpm
148 lbs ft @ 1500 rpm
0-100 kph: 10.7 seconds
Top Speed: 180 kph (113 mph)
Fuel consumption (combined urban/Hway): 3.9 l/100km (60 mpg)
Compare the output of the new MultiJet II engine to the output of the previous diesel engine:
1.3L 16V Turbo diesel
75HP @ 4000 rpm
107 lbs ft @ 1500 rpm
0-100 kph: 12.5 seconds
Top Speed: 165 kph (103 mph)
Fuel consumption (combined urban/Hway): 4.2 l/100km (56 mpg)
Now compare the new MultiJet II engine to the gasoline engine version of the 500:
1.4L 16V gasoline engine
105 HP @ 6000 rpm
97 lbs ft @ 4250 rpm
0-100 kph: 10.5 seconds
Top Speed: 182 kph (113 mph)
Fuel consumption (combined urban/Hway): 6.3 l/100km (37 mpg)
Below are the engine specs for the Fiat 500 Abarth:
1.4 16V Turbo in the 500 Abarth
135 HP @ 5500 rpm
153 lbs ft @ 3000 rpm
0-100 kph: 7.9 seconds
Top Speed: 205 kph (128 mph)
Fuel consumption (combined urban/Hway): 6.5 l/100km (36 mpg)
1.4 16V Turbo with esseesse (SS) performance upgrade kit
160hp @ 5750 rpm
153 lbs ft @ 3000 rpm (170 lbs ft in sports boost mode)
0-100 kph: 7.4 seconds
Top Speed: 211 kph (132 mph)
Fuel consumption (combined urban/Hway): 6.5 l/100km (36 mpg)
What we see is the MultiJet II engine has outstanding performance with a large amount of torque, substantially more than the 1.4L gas engine (51 lbs ft more!). This maximum torque figure is reached at very low revs (1500 rpm or just over idle), and translates to always having lots of passing power available all the time. Driving a high torque car is a treat because you never have to "wind" the engine up, just use slight toe pressure and away you go!
It is the opposite way most small gasoline engines drive, where the peak torque output is high in the rpm range and you're always revving the engine, downshifting and generally working pretty hard to keep up or pass traffic. It's also one of the reasons why Americans traditionally aren't "into" small four cylinder engines.
With the advent of MultiJet II, all that's out the window. This technology has the potential to make as big a difference in the US as it did when Fiat introduced its predecessor, the Common Rail diesel, in 1997. Common Rail changed how diesel engines performed, making them very much "un-diesel like". At once, diesels were smoother, less noisy, less stinky, and more powerful.
Fiat sold this technology off and all major car makers now use it. The result is, in Europe, the market responded by going from a 15% diesel car mix to a 50% mix.
Here in America, we haven't been exposed to this new technology in a large degree because diesel engines are normally available here in only the more expensive car ranges. Now that's going to change.
With MultiJet II, now smaller, less expensive diesels can achieve fantastic performance and drivability gains and still retain the high fuel efficiency, low cost maintenance characteristics that diesels are known for.
Even with Common Rail and MutiJet I, diesels were still down somewhat on horsepower compared with a gasoline engine. Engine displacement was still needed to produce the power the market expected. MultiJet II gives the Fiat engineers the ability to fine tune the engine, maximizing efficiency and power while increasing comfort and refinement with also the potential of reducing displacement.
The proof is in the comparison of the previous diesel engine specs. Compared with the original 1.3L diesel (equipped with MultiJet I), MultiJet II boosts horsepower by 20hp and torque an incredible 41 lbs ft! That's a huge number for a 1.3L engine.
Or, using a theoretical example (using the same specific output of the above MultiJet II engine), you could potentially have a 1.0L diesel engine making 75 hp with a substantial 116 lbs ft of torque! And remember, a physically smaller engine has many advantages over a larger engine, with the same power, in terms of packaging, fuel economy and performance.
All this boils down to a few important points.
First is this 1.3L MultiJet II diesel, being available in the Fiat 500 (which is a relatively lower priced car), offers a new generation of Americans the ability to access a new type of diesel engine with drivability characteristics never before experienced by them. Their experience of driving a highly fuel efficient, powerful, fun to drive car has the potential to make a large impact on what is expected out of a fuel efficient car.
The second point is that after driving a diesel car, many of these owners will look for another diesel car when they move on. Fiat/Chrysler will be in a unique position to upgrade these owners with other diesel offerings. Other car manufacturers will sure to follow with their own diesel offerings (with a licensed copy of MultiJet II, no doubt).
The third point is that all this technology is available today, and it's relatively simple, easily understood compared with electric-hybrid technology. With Fiat's (and now Chrysler's) diesel experience, everyone can start driving a fuel efficient car now and not have to wait or be the beta tester for electric-hybrid technology that still needs a lot of work before it can be used by everyone.
From the above points, we see that MultiJet II could make a big impact on what Americans drive in the future.
So what will it be? A 1.3L 16V MultiJet II turbo diesel or the gasoline 1.4L 16V engine? I know which one I want!
*Fuel economy figures are European and converted to US MPG
The new 1.3 Multijet II (Euro5) engine, with Start&Stop fitted as standard, is making its first appearance on the Fiat 500 and 500C models. It has a maximum power output of 95 HP at 4000 rpm and delivers a torque of 200 Nm (20.4 kg / 148 lbs ft)at only 1500 rpm.
Available on all trim levels, with an on-the-road list price that starts at 13,900 Euros, the new power unit delivers excellent performance (a top speed of 180 km/h and acceleration from 0 to 100 km/h in 10.7 seconds) with decidedly low consumption and CO2 emissions: 3.9 l/100km and 104 g/km (mixed cycle), respectively.
Developed and produced by FPT - Fiat Powertrain Technologies, the 1.3 Multijet II 95 HP engine belongs to the second generation of Multijet power units and has new common rail injectors which, courtesy of a balanced hydraulic servo valve, control the amount of diesel injected into the combustion chamber with a high degree of precision, making the injection sequence much faster and more flexible than previously (up to 8 injections in the same cycle). This allows better control of the diesel combustion with benefits for consumption, emissions, noise levels and drivability.
The new 95 HP engine on the Fiat 500 and 500C is equipped with a variable geometry turbocharger (!) that ensures optimum turbocharging throughout the entire operating range. Fuel consumption has been reduced by up to 8% in the urban cycle thanks also to the Start&Stop system that switches the engine off temporarily and then restarts it. With Euro 5 type-approval, the new 1.3 litre engine enhances its environmentally-friendly pedigree further through the particulate filter (DPF) integrated in the engine compartment which improves its efficiency even more, especially in the first few moments after cold starting.
The second generation Multijet power units represent the development of the common rail injection system which today, after the JTD (1997) and Multijet (2003) engines, allow Fiat Group Automobiles to steal a march in this field and be prepared for future regulations. The Multijet II engines use increasingly advanced "strategies" to improve combustion: for example, the use of injection rate shaping (two consecutive injections with no hydraulic interval) reduces noise, fuel consumption and, in view of Euro 6, harmful emissions (a potential 30% reduction of nitrogen oxides).
Lastly, together with the new 1.3 Multijet II 95 HP engine, the new rear torsion beam (semi-independent) suspension with an anti-roll bar is also making its debut on the Fiat 500 range. It is derived from the Abarth 500 model and has already made an appearance on the 500C. It gives better handling and a more comfortable ride.
