GMC, long a purveyor of trucks and SUVs, surprised the crowd at the 2010 Detroit auto show by rolling out this small concept. The Granite is about the size of a Scion xB, and is powered by a turbocharged 1.4-liter engine. That engine is mated to a six-speed dual clutch transmission, maximizing ease-of-use and efficiency.
The dashboard is inset with a long OLED, showing navigation, climate, audio, and phone, all in a row, keeping each function visible at all times. Instead of a conventional shifter, the Granite uses a knob that the driver clicks into each drive mode.
