GMC has released the first details about the Granite Concept, which will debut at the North American International Auto Show.

Meant to be stylish and functional, the concept measures 60.5 inches (1,536 mm) tall, 70.3 inches (1,786 mm) wide, and 161.3 inches (4,097 mm) long. This makes it approximately the size same as the Scion xB, which GMC has listed as a potential competitor.

In terms of styling, the Granite features a massive grille, 20-inch wheels, and rear-hinged doors like the Opel/Vauxhall Meriva. Other touches include a high beltline, LED tail lights, and a rear spoiler that is integrated into the roof.

Inside, the Granite has aircraft-inspired mechanical instruments and a panel of organic light-emitting diode screens which display information for the navigation, infotainment, and climate control systems. Other features include a Jaguar-like 'knob' transmission shifter, two-tone seats, and satin-finish trim.

Under the hood, power comes from a turbocharged 1.4-liter engine with 138 horsepower (103 kW) and 148 lb-ft of torque (200 Nm). Backed up by a six-speed automatic transmission, the Granite promises to both responsive and fuel-effect.
