Regardless of whether the GT or GTP is chosen, the respective engine is charged with moving about 3,800 pounds of mass, or roughly 400 pounds more than a comparable 2007 Pontiac G6 Coupe. A MacPherson strut suspension keeps the front end riding smooth while a multi-link setup takes care of the rear. Front and rear stabilizer bars, traction control, and stability control systems aim to benefit handling. Stopping the 18-inch alloy wheels wrapped in 225/50 tires is a set of four-wheel-disc antilock brakes, and a large steering wheel is connected to a rack-and-pinion assembly.
