McLaren MP4-12C vs Ferrari 458 Italia: the video

McLaren vs Ferrari: F1's nastiest rivalry is spilling onto the road, and the new issue of CAR Magazine delivers the world's first deep dive comparing Woking's 12C with Maranello's sensational 458. It's the most anticipated supercar showdown for almost two decades, and it's only in CAR magazine (out 18 August). We've stripped the McLaren bare, to deliver a 15-page technical lowdown on the 12C.

Spy Shots: Could this be the 2014 Porsche GT3 RS?

Brenda Priddy & Co. sent us the above photos in an e-mail with the subject line “BREAKING: 2014 911 GT3 UNCAMOUFLAGED!” So, we opened it and found a few shots of Porsche's new rear-engine, mini Panamera in “all black everything” but sporting very little camouflage. If this is indeed the 2014 Porsche 911 GT3 RS, the bodywork is either quite a bit more restrained than that of the outgoing 997.5 GT3 RS, or it's wearing bodywork that won't appear on the 2014 GT3 RS when it debuts at the Paris motor show in September.

The Best (and worst!) of France and Italy

Call this the gathering of cars you're amazed even started. Yet, there were over 300 of them by 11:00 a.m., spread all over the lawn and under the trees in Woodley Park in Van Nuys, Calif. for the annual Best of France and Italy car show.
