18. Abarth 124 Spider

The Abarth 124 Spider proves that lightness and agility can outshine brute force. Its 1.4-liter turbocharged four-cylinder may seem modest at 164 horsepower, but paired with a featherweight chassis, it delivers exhilarating acceleration and responsiveness.
AutoWeek notes that the Abarth 124 Spider routinely punches above its weight, keeping pace with heavier, more powerful muscle cars on both twisty roads and autocross courses.
