Dodge Viper ACR unveiled
The latest track-ready, but street-legal, Dodge Viper ACR has been unveiled prior to going on sale in North America from the third quarter of 2015.
Under that long bonnet beats a hand-built 8.4-litre V10 engine that delivers 481kW of power and 813Nm of torque to the rear wheels via a six-speed manual transmission.
This engine, Dodge claims, has the most torque developed by a naturally aspirated racing engine, although output levels are unchanged over the regular Viper currently in showrooms.
The ACR can be ordered with an "extreme aero" package that includes a massive and adjustable rear wing, removable louvres for the bonnet, four dive planes, a carbonfibre rear diffuser with removable strake extensions, and a detachable extension for the front splitter.
According to Dodge, this package can provide up to 900kg of downforce at 285km/h.
Stopping power is provided by Brembo carbon ceramic brakes all round. Up front the ACR features 390mm discs with six-piston calipers and at the rear there's 360mm discs with four-pot calipers.
The Viper ACR rides on 19-inch alloy wheels and Kumho Ecsta V720 tyres, with 295/25 units at the front and 355/30 rubber at the rear. Allied to this are racing Bilstein coil-over-shocks with 10-way adjustment. All up, drivers can adjust the car's height by around 76mm.
Inside the cabin, the ACR features loads of extra Alcantara pieces, including a grippier Alcantara-clad steering wheel. As with the Viper GTC, the ACR will be offered with a one-to-one customisation scheme that allows for 25 million different interior and exterior combinations, including unique paint, stripes, alloys and interior trim.
Details about pricing have yet to be released.
