Under the hood is the production 6.0L V-8, rated at 361 horsepower (268 kW) and 385 lb.-ft. of torque (520 Nm). A six-speed automatic transmission with Driver Shift Control backs the powerful small-block engine and complements a four-wheel independent suspension outfitted with unique 20-inch wheels and performance tires.

Standard ABS and traction control augmented by high-performance HSV brakes

Roof rail side-impact air bags for both seating rows
OnStar with available Turn-by-Turn navigation
Power-adjustable front seats
Fog lamps
Quad polished stainless steel exhaust tips
Rear lip spoiler
Augmenting the SEMA Edition is a series of modifications, including:

Custom orange exterior paint
Orange-accented interior components, including seat inserts, door panels and instrument panel pad
Enhanced brake package with drilled and slotted rotors
Lowered performance suspension package
Twenty-inch wheels with performance tires
The G8 has a progressive styling package highlighted by strong Pontiac design cues, such as a dual-port grille, fog lamps, bold wheels and a confident, wheels-at-the-corners stance. The car’s design accents Pontiac’s performance lineage, with fenders that flare over the wheels, seemingly hugging the wide tires and enhancing its athletic stance.

Distinctive elements include hood scoops and front fender vents, as well as projector-beam headlamps housed in crystal-clear lenses. At the rear, taillamps feature bright detail work surrounding the red lighting elements.
