It appears Dodge is in the Halloween mood already. Its new Viper ACR has kicked off our week off in somewhat scary style.

Just look at it: the Viper is hardly a shrinking violet to begin with, but Dodge has seen fit to crank its road presence up by several hundred per cent.

As well as its bold white, black and red colour scheme, there's a carbon front splitter, some rather serious looking dive planes, a set of 19in lightweight alloys and one of the biggest, maddest wings we've seen in a long time.

The size of the rear spoiler gives a good hint as to where the Viper ACR will feel most at home: on the track. This is just a show car, so there aren't any stats on how much downforce it produces just yet, but it's safe to place your money on 'LOTS', we reckon.

Other changes are equally circuit-minded, with fripperies like carpets and sound insulation culled in the name of weight saving, some seriously powerful Brembo brakes and retuned suspension. There's no word on whether the Viper's engine gets a tickle, but with its 8.4-litre V10 pumping out 640bhp as standard, it's not an area we would make priority.

While this is a show car for next week's SEMA show, it's fair to assume it will make production. The Viper ACR has previous, the previous iteration setting a 7m12s lap of the Nürburgring.

With the similarly demonic-looking Nismo GT-R a tantalising four seconds ahead, who'd bet against Dodge putting the ACR into production and sending it Nissan-hunting?
