Which is faster? An Ariel Atom V8 track day toy, BMW HP4 superbike or a rallycross Citroen DS3 with 600bhp?

Here we have three completely different ways of going extremely quickly in a straight line. Time for a drag race then. So what are the contenders? There’s the one-wheel drive BMW HP4 superbike, which arguably requires the most skill to extract speed from but has a ludicrous 757bhp/tonne power-to-weight ratio. Then there’s the two-wheel drive Ariel Atom V8 with 748bhp/tonne and the Citroen DS3 Rallycross car with only 577bhp/tonne but all-important four-wheel drive. Oh, and did we mention it’s wet?

Autocar, the world’s leading motoring magazine and website, delivers industry-leading news, the most in-depth car reviews and opinion from our team of experts. Our presenters include some of the world’s top motoring journalists who have unrivalled access to the world’s fastest, rarest, most exotic and most exciting cars on some of the world’s best roads and race tracks.

Can a supercar beat a superbike? Can a Audi A1 outrun a Nissan GT-R on a wet circuit? Can a Porsche 911 slay a Corvette on the drag strip? Autocar pitches the giants of the performance car world against each other to deliver the all-important verdict.

Red Bull Rusch Hour began at midnight on April 27, 2013, with Rusch starting her journey down the iconic 142-mile Kokopelli Trail in an attempt to break the female time record of 15 hours, 3 minutes (set by Lynda Wallenfels in 2006).

Rusch rode unsupported from Moab, Utah to just outside Fruita, Colorado, crushing the record by almost two hours, achieving a final time of 13 hours, 32 minutes.

Now that Rusch has finished her record-breaking attempt, amateur riders are challenged to #JoinTheRusch, to tell their story about how they challenge themselves on the Kokopelli Trail or any other 142-mile trek of their choice. Learn more here: http://win.gs/11QjZ3j

On this episode of Head 2 Head, Motor Trend’s Jonny Lieberman pits the 2013 Range Rover against the 2013 Mercedes-Benz G63 AMG. Several technical & challenging obstacles await as these two SUVs navigate a purpose-built off road course. Did we mention that the course also happens to be the testing grounds for Motor Trend’s SUV of the Year? Old school meets new school as tried & true German engineering squares off against cutting edge British gadgetry.

Of course, no comparison between these two status symbols would be complete without a visit to their natural habitat… the mean streets of Beverly Hills, CA. While both of these contenders will get you through the dirt in style, which of these two uber-luxury six figure SUVs is most befitting of high society? Join us as we find out.

Head 2 Head appears every other Wednesday on the Motor Trend channel. http://www.youtube.com/motortrend
