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. 2013 Abarth 500 Interior.
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.
