Endowed with the most powerful four-cylinder engine in the GM family, the 2007 Pontiac Solstice GXP’s 2.0-liter delivers 260 horsepower and 260 lb.-ft. of torque, enough power to propel the GXP to 60 mph in under 5.5 seconds. That will make even the proudest of MX-5 owners feel a bit slow and chumpish one lane over, and maybe a little envious. Also standard are features such as a dual-outlet exhaust, StabiliTrak stability control, a sport suspension, four-wheel-disc antilock brakes, a limited-slip rear differential, power window/locks/mirrors, remote keyless entry, and 18-inch polished aluminum wheels. Options for the 2007 Pontiac Solstice GXP include a rear deck spoiler, leather seating, metallic sport pedals, chrome wheels, enhanced audio options including XM satellite radio, and OnStar telematics. You can tell the GXP from a regular Solstice by looking at the styling front and rear.
