7. Pontiac Solstice GXP
While the Solstice convertible carved its niche as a stylish roadster, the GXP variant (2007-2010) turned heads with a turbocharged 2.0-liter Ecotec four-cylinder churning out 260 horsepower and 260 lb-ft of torque. That output hurled the two-seater from 0-60 mph in just 5.5 seconds, rivalling many V6 competitors.
A sport suspension with monotube front shocks and a stiffer rear sway bar sharpened turn-in response, while four-wheel disc brakes with 12-inch front rotors provided fade-resistant stopping power. The lightweight, rear-wheel-drive chassis made the Solstice GXP feel agile and playful, while its muscular wheel arches and dual exhaust tips hinted at the potent performance hiding behind the sleek design.
