2005 GMC Graphyte

GM has really put its engineering resources into hybrids: witness the Graphyte concept SUV. A combination of a Displacement-on-Demand 5.3L V-8 and dual electric motors improve fuel economy up to 25%. The electric motors are powered by a 300V NiMH battery pack. A infinitely variable ratio gearbox improves transmission efficiency and fuel consumption. The Graphyte features a rugged ladder frame and adjustable ride height. A new Advanced Automatic Crash Notification detects collisions and records relevant vehicle data to assist emergency responders. The Graphyte interior features Mokanto wood, leather, and aluminum trim. Dual overhead skylights add open air visibility.
