2006 Pontiac Solstice First Drive

Regardless of chosen equipment, all 2006 Pontiac Solstice models are propelled by a proven 2.4-liter Ecotec four-cylinder that dispenses 177 horsepower at 6,600 rpm and 166 lb.-ft. of torque at 4,800 rpm. Cracking the substantial front-hinged, clamshell hood reveals a mill with aluminum construction, dual overhead cams with four valves per cylinder, variable valve timing, twin counter-rotating balance shafts, hydraulic mounts, and direct mounting of accessories to the engine, which decreases underhood space requirements and weight while also reducing vibration and noise. A five-speed manual transmission directs power to the rear axle. Compared to the Solstice, the 2.0-liter engine in the Mazda MX-5 is close in terms of horsepower, yielding 170, but trails a tad in twist with only 140 lb.-ft. of torque. However, MX-5 Miatas arrive with both five- and six-speed manuals and an optional six-speed automatic, and the MX-5 has a lower base curb weight by 410 pounds.

Underneath the 2006 Pontiac Solstice, fully independent suspension and a rear-drive layout contribute to a weight distribution of nearly 50/50 front to rear. Power assisted rack-and-pinion steering changes direction while 11.7-inch front and 10.9-inch rear disc brakes with optional ABS shed speed when necessary. GM's Kappa structure uses hydroformed frame rails, rather than welded structures, to increase strength and simplify the construction process. The suspension configuration is a short/long-arm setup at both ends of the vehicle. At 2,860 lbs. the Solstice is significantly heavier than the Miata.
