First Sight: BMW Zagato Coupé

"I've been looking for a way to collaborate with Zagato and Nori [Norihiko Harada, Chief Designer Zagato] for around 20 years," explains Adrian van Hooydonk, Senior Vice President BMW Group Design as we stand in the shadow of the magnificent Villa Erba. "Last year at this event we had a conversation and decided that it was the right time to do something." BMW and Zagato both have history associated with the Concorso d'Eleganza Villa d'Este – Europe's most glamorous car show – yet until last weekend the two illustrious names had never crossed paths. The BMW Zagato Coupé marks the first project between the two and the first Italian-designed car to wear the blue and white propeller since the 2003 Bertone Birusa.

McLaren P1: New photos & video of production P1

The McLaren P1 production car pictured hot weather testing We’ve had a surprising amount of McLaren P1 news in the last couple of weeks, with a claimed lap time at the Nurburgring that didn’t quite meet expectation, P1 customer Jay Leno getting to grips with the P1 at the Top Gear track  and the news that the P1 is all but sold out. Now, with the first P1s getting close to delivery (McLaren are about to start building customer cars at the rate of one a day), McLaren has released photos and video from their final stint of hot weather testing in the US, with a completely undisguised, production version P1. McLaren have been in the west of the US, where temperatures reach 52 degrees, putting the P1 through its paces in extreme heat in California, Nevada and Arizona, both on the road and at the Willow Springs International Raceway in California, just to be sure it doesn’t melt in the sun.
