2008 Pontiac Solstice GXP

Performance

The surge in strength from the base model's 177 hp to the GXP's 260 lowers the Solstice weight to power ratio from a sports car typical 16.9, to 11.5—approaching the supercar, single-digit range. The boost in brawn also has an obvious (and positive) impact on the car's driving dynamics. Power arrives in force as the tach swings past 2,500 rpm, and the turbocharged four whistles its way from 0-60 mph in about 5 seconds. Interestingly, the pumped-up motor exacts no penalty at the gas pumps. On the contrary, using EPA mileage estimates from 2007 ('08 figures not yet available), Solstice nets 20 mpg city/28 highway. The GXP weighs in at 22/31. We averaged 27 mpg on our test drive overall, logging 30 mpg on highway runs. The five-speed manual shifter works pretty well, though it's not in the class of the Miata, the segment's shifting benchmark.


Also interesting is the fact that the GXP's power doesn't overpower the chassis. The suspension is firm—stiffer than base models, though not at the cost of ride quality. Beefier stabilizer bars fore and aft and performance-rated tread (in place of all season tires) help boost grip. The GXP is indeed a fine handler, cornering flat with understeer only appearing when heavily pushed. ABS, an electronic stability system (defeatable) and a limited slip differential are all on board, to help the sportiest Solstice track true.


Despite grumble points like a slow-to-drop top and a luggage-adverse trunk, GXP remains a highly appealing choice, offering a distinctive alternative to such segment stalwarts as the Mazda Miata and Honda S2000. The Pontiac is less track-worthy than the high-strung S2000, but more street-friendly. It's less smooth and refined than the Miata, but far more powerful and decidedly edgier in design. Indeed, the GXP's combination of looks, power and handling rivals sports cars with considerably larger price tags. That's one big reason why the small, Solstice twins have collectively captured the sales crown in the two seater-segment, despite their newcomer status. (www.pontiac.com)
