Nissan Extrem SUV concept (2012) first official pictures

Nissan is looking to bring a splash of colour and outlandish design to Brazil's streets with their latest creation: the Extrem SUV concept. It's an eye-grabbing response to the 'more affordable locally produced vehicles, which tend to be conservative in design, colour and specification', according to company Senior Vice President Shiro Nakamura. What niche does the Nissan Extrem fall into? If the love-it-or-hate-it Nissan Juke is the marque's jacked-up supermini crossover, the Extrem is the rakish, sportier version of that: a sort of X6 to the Juke's X5, if you will.

Audi TT ultra quattro concept sheds 300kg & heads for Worthersee

The TT ultra quattro concept manages to tip the scales at 1111kg, 299kg less than the starting point – the TT S quattro – thanks to a new version of the TT’s aluminium space frame, carbon fibre reinforced plastic panels, carbon fibre for many body panels and some judicious use of magnesium. Other weight saving tricks include carbon ceramic brakes with aluminium calipers, titanium exhaust, cameras instead of heavy door mirror mechanisms, and carbon fibre and aluminium wheels. The weight saving extends to the interior of the TT ultra quattro concept too, with carbon fibre used for the door and centre console trims and glass-fibre reinforced plastic base for the seats which saves 22kh alone. But despite the weight savings Audi hasn’t made the TT ultra quattro concept a hair shirt outing with goodies like leather seats, AirCon and electric windows still on offer.

Top Gear Tonight: Ferrari F12, BAC Mono, Ron Howard & the world’s best taxi

Jeremy drives the BAC Mono (pictured) in tonight’s Top Gear Tonight’s second episode of series 20 of Top Gear gets back to the usual format. The new reasonably priced car is in action for the first time as film director Ron Howard – who’s just done Rush, which chronicles the rivalry between James Hunt and Niki Lauder during the 1976 F1 season – gets behind the wheel of the Vauxhall Astra to set a lap, talk about cars and his new film. Jeremy Clarkson gets to play with the stunning Ferrari F12 Berlinetta, which with 731bhp, 0-62mph of just 3.1 seconds and a top speed of 211mph should induce more than a grin or two from Jezza as he takes to the roads of Scotland.
