Looking sleek and sinister, the model features an evolutionary design with bi-xenon headlights, a double-bubble roof and side-exiting exhaust tips. The rear end bares some resemblance to the Maserati GranTurismo but adopts a massive rear spoiler and LED taillights.
While the previous Viper had a parts-bin interior, the new cabin is significantly improved with higher quality materials and advanced technology. Notable highlights include leather upholstery, a digital instrument cluster and Sabelt racing seats which sit 20mm lower and have an additional 90mm of travel. There's also metallic accents, a Harman Kardon audio system and an 8.4-inch Uconnect infotainment system.
Motivation is provided by an 8.4-liter V10 engine which has been equipped with a composite intake, high-strength forged pistons, sodium-filled exhaust valves and new catalysts. Thanks to these modifications, the aluminum mill produces approximately 640 hp (477 kW / 649 PS) and 600 lb-ft (814 Nm) of torque - 40 hp (30 kW / 41 PS) and 40 lb-ft (54 Nm) more than the previous engine. It is connected to a six-speed manual transmission which sends power to the rear wheels via a speed-sensing limited-slip differential.
Besides being more powerful, the Viper has gone on a diet full of lightweight components. The car's tubular steel space frame has a magnesium cowl and is covered by a body which features a carbon fiber hood, roof and liftgate as well as aluminum doors and plastic quarter panels. This enables the entry-level model to tip the scales at 3,354 lbs (1,521 kg) which is approximately 100 lbs (45 kg) less than the previous Viper.
To ensure the car handles like a proper supercar, it rides on a new chassis which is 50 percent stiffer than its predecessor. In order to get this impressive figure, engineers installed an aluminum X brace that "ties the suspension pickup points to the magnesium cowl super casting and contributes to improved torsional rigidity and stiffness." Elsewhere, there's a new rear suspension, Brembo brakes, electronic stability / traction control and 18- / 19-inch wheels with Pirelli P Zero tires.
The standard Viper will be offered with an optional SRT Track Pack and in GTS trim. The Track Pack adds Pirelli P Zero Corsa tires, a four-mode traction / stability control system and unique Brembo brakes. On the other hand, the GTS has a leather-wrapped dashboard and driver selectable Bilstein DampTronic shock absorbers.
