Saab 9-4X

The production version of the new Saab 9-4X will make its official debut at next month's LA Auto Show, exactly two years after it was first displayed as the 9-4X BioPower concept. It shares its platform with the Cadillac SRX. Very little appears to have changed in the intervening period, with Saab design director, Jason Castriota's appointment coming after the car was signed off under GM's tenure.

Aston Martin Vanquish Carbon Edition – costs £200,000

The Aston Martin Vanquish Carbon Edition in Carbon White It’s only a month since the 2015 Aston Martin Vanquish (and Vanquish Volante) were revealed with a series of updates that manage to turn the Vanquish in to a much more appealing car. That new appeal is mainly down to AML finally ditching their ancient six-speed auto ‘box and replacing it with a new 8-Speed ZF ‘box – which cleverly sits inside the old housing – increasing performance, drivability and economy in one fell swoop. The Vanquish now gets to 62mph in a very respectable 3.8 seconds and can top 200mph, despite which official economy improves to 31mpg (more like 16mpg in the real world).

Rumormill: Aston Martin Cygnet could get V12

That's right, Autocar reports that Aston is studying the feasibility of taking the Toyota iQ-based Cygnet and shoehorning the V12 from its Vantage and DB9 models. Aston says it could fit the V12 in the tiny car's engine bay without major modifications.
