NY Show: 2009 Pontiac Solstice Coupe with Targa-Top

Pontiac is broadening the Solstice’s line-up with the introduction of a coupe version that’s inspired that’s by the homonymous 2002 Detroit Show concept. The coupe features a removable hard top panel in case you lust to see the sun, but unfortunately, there’s no space in the rear to store it. Instead, Pontiac offers an optional soft roof cover that can be stored in the cargo area when not in use.

There are no mechanical changes since the change to a coupe body style resulted in only a slight increase in curb weight. Pontiac notes that initial tests have shown that the Solstice coupe will deliver ride and handling, acceleration, braking and fuel economy comparable to the convertible model.

As with the roadster, the coupe is powered by a standard 173 Hp 2.4L four-cylinder engine, while the GXP version is equipped with a 260 Hp 2.0L turbocharged engine. The Solstice coupe is expected to arrive in Pontiac dealerships in early 2009. (Pics edited by Carscoop) – Details and pics after the jump
