The hand-assembled 8.4-liter V10 produces a factory-rated 640 horsepower and 600 lb-ft of torque. Power reaches the rear wheels through a six-speed manual transmission and a 3.55:1 limited-slip differential, with an aluminum structural X-brace spanning the engine bay. Carbon-fiber hood, roof, and decklid panels are paired with aluminum door panels, while black-finished Viper-branded Brembo calipers clamp ventilated rotors at each corner.
