Terra4's unconventional package - a totally integrated design and closed body, with a short, deep cargo area - permits greater functionality and utility than a pickup truck. Doors on the rear quarter panels allow easy access to the closed cargo area. The passenger cab is moved up and forward, creating interior cargo space behind the second row of seats. The four-door truck also is loaded with features that would exceed the expectations of the most demanding customers. The concept vehicle combines the fuel efficiency and power-on-the-go capabilities of a parallel hybrid V8 engine with the car-like maneuverability of GM's exclusive four-wheel-steering. Terra4's aerodynamic cab up and forward architecture is the foundation for superior sight lines and a spacious interior that is finished in leather and brushed metal trim accents. Soft glow analog gauges represent precision and complement the oversized controls for better sight and feel.
Leather and brushed stainless steel dominate the interior, creating a sense of functional luxury and durability. The analog gauges, which feature amber, soft glow lighting, with digital display technology, were inspired by the rugged, functional timepieces worn by divers and pilots. Controls are slightly oversized for a more solid appearance, comforting grip and professional-grade feel. Terra4 also features an integrated vehicle information center and modular compartments mounted on the doors.
Terra4's powertrain is derived from GM's innovative Parallel Hybrid Truck, which brings together the Vortec V8 gasoline engine and a powerful electric motor/generator. A 4.8-kilowatt motor/generator is integrated into the drivetrain between the gasoline engine and the transmission. This provides starting power and the ability to generate electricity during deceleration. It also saves weight and parts because a conventional starter and alternator are no longer needed. At a stoplight, the gasoline engine shuts off, but the accessories continue working on stored electrical power. When the light turns green and the driver depresses the accelerator, the gasoline engine restarts automatically. The truck gets more miles per gallon because of the stop/start function, torque-smoothing for improved powertrain efficiency, and regenerative braking, which turns the motor into a generator to capture energy as the truck decelerates.
