Infiniti M

Less than two years after the mid-life facelift of its 'M' series luxury sedan range, Infiniti has taken the wraps off an all-new 2011 version. Launched 'virtually' at the recent Pebble Beach Concours d'Elegance, the third-generation M is scheduled to be publicly unveiled later this year bearing toned-down styling cues from the company's Essence concept. The influence of the Essence is most apparent in the sedan's undulating character line and the way that the hood plunges down to meet a low-set front grille complete with concave outer edges.

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.
