Nissan 370Z Roadster (2009): full official photos

By Tim Pollard First Official Pictures 07 April 2009 22:01 Nissan has released its full official photos of the new 370Z Roadster in New York ahead of its debut at the 2009 auto show. As expected, it's a straightforward decapitation of the thrill-seeking 370Z Coupe, with a good, old-fashioned canvas soft-top in keeping with the Zed's no-nonsense character.There's structural reinforcement in the A-pillars and side sills to counter the lack of roof, but Nissan says numerous body panels are made from aluminium to keep weight in check. The bonnet, door panels and bootlid are all crafted from the lightweight metal and there are individual, fixed roll bars behind each seat.Providing the fun is the 327bhp/270lb ft 3.7-litre V6 with variable valve lift and the choice of a seven-speed auto or six-speed manual transmission.

New Audi Q7 (2013) to shed weight. But no Audi Q9 planned.

The 2013 Audi Q7 will be much lighter than the current Q7 The Audi Q7 was rather late to the SUV party of the noughties, not hitting the road until 2005. That meant the Q7 had a bit of an edge when it launched, as it was newer than its competition, but it also means the Q7 is still soldiering on when its competition has already launched newer, shinier models. But Audi are working on fixing that, and fixing the biggest criticism of the Q7 in the process – its sheer weight and size.

Concept Car of the Week: AMC AMX/2 (1969)

Like Detroit's Big Three, AMC rapidly understood the importance of the youth market after the success of the Ford Mustang. In the late 60s, the design team produced a series of "Think Young" concept cars to reach the younger audience as well as exciting new showroom offerings like the Mustang-inspired Javelin, the two-seater AMX and the Rambler. Presented at the 1969 Chicago auto show, the second opus of the American Motors Experimental series, the AMX/2 was not just AMC's most daring concept car ever, but one of Detroit's first acknowledgments that the future of high-performance sports cars would be mid-engined.
