The Hamann tuning firm is a well known BMW and luxury car tuner, but have now added the Fiat 500 Abarth to their list of modified cars since it is extremely popular. This new program for the Cinquecento features a new aero kit to make it much more aggressive. Hamann also offers several performance packages to the car to a new level. As for the aerodynamics, they chose to modify the Fiat with a new front skirt, integrated LED daytime running lights, wing extensions, side skirts, and a redesigned rear skirt with Ferrari-like diffuser. However, the performance gains for the small engine Fiat 500 Abarth are jaw dropping.
Hamann offers the HS I performance pack that includes a remapping of the ECU to boost the numbers to 160 hp and 285 Nm of torque. The next level, HS II, adds a new full exhaust system from the exhaust of the turbo to the tips at the muffler to raise the figures to 180 hp and 295 Nm of torque. The kit right in the middle, the HS III for the Fiat 500, increases the horsepower and torque to 210 hp and 310 Nm with the addition of a better performing turbocharger and new fuel supply.
Now here’s the good stuff. Hamann’s fourth level for the Fiat 500 Abarth is called the HS Race, and offers quite a bit of extensive tuning. Their company installed forged pistons, aftermarket connecting rods, a modified turbo charger, race clutch, and a weight optimized one-mass flywheel to give the Fiat 240 hp and 330 Nm of torque. The most powerful kit is called the HS Cinquecento 575, and it includes everything mentioned above, along with a re-engineered cylinder head with adjusted camshafts, two charge air coolers, and a self-locking differential. The power numbers from this package show 275 hp and 380 Nm of torque.
The wheels you see pictured are a newly developed design, Largo Forged Anodized available in 18×8 for the front, and 18×9 at the rear. Hamann also offers a variety of sport suspension kits for the Fiat 500 to ensure improved handling. With the power kits mentioned above, it is also recommended to have them install a high performance braking system for the very fast 500 Abarth.[Source: carsroute]
