In the new July 2011 issue of CAR Magazine (out on Wednesday 22 June) we've pitched the McLaren MP4-12C against its most important rivals, the Ferrari 458 Italia, the Audi R8 V10, Lamborghini's Gallardo Performante, the Porsche 911 GT2 RS, and the Macca's long-lost cousin, the Mercedes SLS AMG. We've flown in European editor Georg Kacher and made Gavin Green empty his diary, two legends who've driven every landmark supercar over the past 30-odd years. Together with the rest of the CAR road test team they put these six sublime supercars through their paces over two memorable days in Wales.

The CAR team also descended upon Rockingham race circuit so Le Mans driver Ben Collins could lap each one against the clock. At the end of three days testing we picked our winner, the very best supercar on sale today. Read the full story in the new July 2011 issue of CAR, but over the coming days we'll publish videos of all the timed laps, along with blogs, outtakes and galleries from 2011's most important supercar test.

Check out the timed laps in the hands of ex-Stig Ben Collins at Rockingham in our onboard videos below. We'll add a new supercar each day in the run-up to 22 June, when the new issue of CAR goes on sale.
