The Pontiac Solstice is powered by a 2.4-liter, 177-horsepower four-cylinder engine. For now, the only transmission available is a five-speed manual; buyers willing to wait until early 2006 will have the option of a five-speed automatic. The Solstice has hand-cranked windows, manually adjusted outside mirrors and finger-powered door locks. Dual-stage front airbags are standard. Optional antilock brakes come with dynamic rear proportioning, which electronically balances force front and rear to maximize braking while avoiding rear wheel lockup, similar to electronic brake-force distribution or EBD.The Pontiac Solstice is all new for 2006.
