Land Rover Range Rover [w/Gallery]

The first images and details of the fourth-generation Range Rover have been released, with a notable upward shift in size and 'dynamism' for the full-fat RR. The outgoing version brought with it a dramatic increase in size to make way for the smaller Sport and this new one grows to truly 'full-size' dimensions.

The new Alfa Romeo MiTo TwinAir is a logical move by Alfa to produce a MiTo with green credentials but which still offer a decent drive and a dose of fun.

Petrol cars twice as likely to fail MOT on emissions

The latest MOT test data shows that 26.2% of all cars tested fail on excess exhaust emissions – and surprisingly petrol cars fail more than twice as often as diesels in this part of the annual roadworthiness test. According to the official Vehicle Operator and Standard Agency (VOSA) figures, which cover all of 2010 and the first nine months of 2011, 9.7% of petrol cars failed to meet MOT emissions standards compared to just 3.9% of diesels.
