Like the Fiat 500 Abarth, the new
2013 Fiat 500C Abarth features the track-proven 1.4-liter MultiAir Turbo
engine for 160 horsepower, up to 170 ft.-lb. of torque and 0-to-60 mph
performance in the low 7 second range. Compared with the Fiat 500C's
naturally aspirated 1.4-liter MultiAir engine, the boost to 160
horsepower on the Fiat 500C Abarth is largely due to its single
turbocharger that operates off engine exhaust and utilizes energy that
would normally be wasted through the tailpipe.
The
turbocharger spins up to 230,000 rpm to convert exhaust heat and
pressure to a rotational force that drives a compressor. The compressor
draws cool air and pumps it into the intake manifold at increased
pressure (maximum 18 psi / 1.24 bar) that results in a greater amount of
air in the cylinder and, hence, more power. The 1.4-liter MultiAir
Turbo's induction system includes two intercoolers located behind the
driver- and passenger-side air inlets of the Abarth-styled front fascia.

The
intercoolers are designed to remove heat in the air charge that the
turbocharger generates while compressing incoming air (higher air
density for more power). Reducing heat provides a cooler, denser air
charge that helps increase the potential for more power. Other
high-performance engine component upgrades include an Abarth-designed
fresh-air intake system with high-flow air filter and smooth-flowing
plumbing for maximum power.
And
to make sure the engine is operating with minimal exhaust gas
restriction, an Abarth-designed concentric "double-tip" dual-exhaust
system delivers a high-performance look with menacing Abarth-tuned
sound. Developed for high-output applications, the Fiat 500C Abarth is
equipped with the track-proven C510 five-speed manual transmission.
Proven on the European 500 Abarth models, this transmission features a
3.35 final-drive ratio for quick acceleration and faster top speed,
while maintaining fuel efficiency.
Designed
to handle the increased torque loads, the Fiat 500C Abarth's C510
transmission includes an intermediate shaft with equal-length half
shafts to mitigate torque steer. Compared with the Fiat 500C, the 500C
Abarth features 23 percent larger half shafts (28.1 mm diameter vs. 22.8
mm diameter in the Fiat 500C) for increased strength and to reduce
torsional stress in the driveline during performance driving on the road
or track.
