The FIAT 500 is presently the best designed ultra compact car on the market, and it’s finally available in America. But the version we’re getting imported has just a measly 101 hps, with an Abarth 133 hp tuned version coming in early 2012. But besting that output by a significant amount is Italian tuner Romeo Ferraris’ Abarth Cinquone Stradale which tweaks the 500’s 1.4 litre turbocharged engine to generate an eyebrow-raising 300 horses. The car also gets a steroid body kit, new lightweight wheels, racing bucket seats with four-point harnesses, roof spoiler, rear diffuser and a racing-spec roll cage just in case you push your Abarth Cinquone Stradale a little too hard on the track. No word yet on price or availability yet, but surely a Cinquecento you’ll want to keep your eyes on…
