Scion has always aimed at younger buyers, and for 2007 it's offering the tC sport coupe with a Spec Package model designed just for them. Dubbed the Spec trim, Scion's intention is to have this model serve as a blank canvas to be used as a starting point for customization. The Spec trim trades the base trim's 17-inch wheels for 16-inchers, foregoes the base model's power sunroof for a fixed glass roof and offers unique upholstery and interior trim. The 2007 Scion tC hatchback is ably powered by its standard 2.4-liter, four-cylinder engine. This is a big engine for a class in which 1.7-2.2 liters is more the norm. The tC's motor offers more muscle than starter engines in the Civic and Ion coupes, generating 160 horsepower and 163 pound-feet of torque.
