A Look at the Fiat 500 Abarth Turbo Boost Gauge

Fiat 500 Abarth Turbo Boost Gauge

One item that is sure to keep your attention in the new 2012 Fiat 500 Abarth is the turbo boost gauge prominently displayed to the left of the instrument panel.

The engine management system in the Fiat 500 Abarth intelligently regulates turbo boost pressure based on environmental (ambient, elevation, etc.) and engine operating conditions. This way, folks living in high altitudes can experience the full 160 HP and 170 lbs-ft of torque the 1.4 L Turbo engine delivers. The turbo boost gauge indicates the intake manifold pressure (boost level) relative to barometric pressure.

The turbocharger pressure reading on the boost gauge normally runs to 18 psi (1.2 bar) depending on the above condition requirements.

Operation
The warning light in the boost gauge signals the ideal time to change gears. The gear change indication (arrow pointing upwards and words SHIFT UP) displays a suggestion to change up to a higher gear.

With the ignition in the MAR (run) position, the gear change indicator lights up and goes out together with the instrument panel warning lights. Afterwards, the up arrow and the words SHIFT UP light up each time there is a suggestion to change to a higher gear.

Note: The light signalled provided by the instrument depends on the driving mode selected.

With the SPORT mode on, the signalling is only activated at the maximum engine speed.

With the NORMAL mode activated, the signalling is determined by the engine computer to achieve the best driving economy.

================================

This is one feature that new Abarth owners will thoroughly enjoy!


This information is based on the operation of the European 500 Abarth's boost gauge.  The one in the  US Fiat 500 Abarth is expected to operate similarly, but check your owners manual for any differences.
