The Solstic’s basic structure started life as a derivative of GM’s global small car architecture, with several modifications for structure and balance, including extensive use of aluminum.
The Solstice is powered by a rear-wheel-drive 2.2-liter DOHC supercharged EcoTec four-cylinder engine generating up to 240 horsepower with premium fuel. The supercharger is an off-the-shelf unit supplied right out of the GM Service Parts performance catalog. The engine is mated to a Borg-Warner performance six-speed manual transmission, the same one used in the Corvette.
The front end uses a simple and reliable strut configuration with a rack-and-pinion steering system derived from the Subaru WRX, one of GM’s alliance partners. The all-aluminum independent rear suspension is derived from GMs mid-size crossover SUV family and also doubles as the mount for the rear differential, which was derived from the new GM mid-size SUVs. Unique fabricated drive-shafts power the rear wheels.
