2013 SRT Viper officially unveiled at New York show

The all-new 2013 SRT Viper has been unveiled at the 2012 New York International Auto Show in the US. It features sharp new styling, and a very powerful V10 engine.

There’s been a few teasers and leaks in the recent past surrounding the 2013 SRT Viper, but up until now the engine specs have been kept a tight secret. It features an 8.4-litre V10 (not the previously speculated 8.7), producing 477kW (640hp) of power and a colossal 814Nm of torque.

The engine is made up of forged pistons, a composite intake, and an aluminium block to keep weight to a minimum, while underneath features ‘sodium-filled’ exhaust valves and new catalytic convertors.

All that power is sent through a conventional, and presumably very heavy duty, six-speed manual transmission and limited-slip differential at the back. Acceleration performance and a top speed is yet to be announced.

Like the previous model, Dodge and SRT have focused on keeping overall weight to a minimum. So, the 2013 SRT Viper is built up from a steel space frame, which is up to 50 per cent stiffer than the old chassis, covered in a carbon fibre bonnet and roof, aluminium doors, and plastic rear guards, all resulting in a weight of 1521kg – around 45kg lighter than the old model.

Inside, the new Viper has really stepped up a notch in terms of quality and overall design. There’s plenty of metallic highlights, Sabelt bucket seats, a Harman Kardon sound system with an 8.4-inch Uconnect interface, leather, and a digital instrument cluster.

On the outside, the 2013 SRT Viper gets the trademark side-exit exhausts and double bubble roof profile, as well as LED lights in the front end, and offset 18- and 19-inch alloy wheels.
