It’s the fastest street-legal Viper ever
We caught our first glimpse of this hardcore Viper ACR at SEMA last year, but now we have some actual details. It’s billed as the ultimate track-honed Viper, built to “dominate road courses around the world”.
And as with any self-respecting track car, the upgrades over the ‘standard’, 8.4-litre, V10-engined Viper cover the aerodynamics, the chassis and the rubber. First up is something called the ‘Extreme Aero Package’, and it is quite extreme.
There’s a detachable extension for the front splitter, four dive planes, a new SRT bonnet with removable louvres, a rear carbon diffuser, and one of the most excellent rear wings in existence: a fully adjustable effort standing 1.8 metres wide.
“During on-track testing,” Dodge tells us, “development engineers have experienced nearly one tonne of downforce at a top speed of 177mph.” In fact, this new aero pack offers up three times more downforce than the Viper Time Attack 2.0.
There are new adjustable, aluminium Bilstein racing shocks, a 3-inch ride height adjustment, stiffer front and rear springs, 1.4 degrees more negative camber, stickier, low-profile Kumho tyres apparently good for a 1.5-second-per-lap advantage, a specially tuned stability control system, and bigger Brembo carbon ceramic brakes.
The engine is the same 8.4-litre V10, here producing 645bhp and a handy 600lb ft of torque. In this ACR, it gets new tips to reduce pressure on the side exit exhausts. It’s matched up to a six-speed manual, driving the rear wheels.
Dodge has kitted out some ACR-themed trinketry inside, too, and there’s also the option of customising your Viper to beyond normal human comprehension. There’s no word on price just yet, but the hand-built ‘American Club Racer’ is slated to go on sale later this year.
The ultimate in American muscle? Or just too much?
