500 Abarth's motivation comes from a turbocharged version of the 1.4-liter four-cylinder engine pumped to 160 hp and 170 lbs.-ft. of torque, a 60-hp gain on the everyday 500. The suspension gets lowered and toughened, the brakes upgraded, the interior redone and the dual exhaust tuned to buzz like an angry junebug on a string, just as Karl liked it. Fiat says 60 mph arrives in 7.5 seconds of pedal pushing, two seconds and change faster than the regular edition.At a base price of $22,000 before destination charges, the 500 Abarth plays in an interesting neighborhood.
