Driven: Nissan Juke

Nowhere is the fragmentation of established market segments more evident than when thumbing through Nissan's current brochures. The new Nissan Juke, the smallest and most extreme member of Nissan's crossover range, is pitched as an 'urban proof' alternative to more conventional superminis.

2009 Mercedes-Benz S Class

The Mercedes S Class has long been at the forefront of car technology. You can bet your boots that what we see on any new S Class will be where mainstream makers go in years to come.

Bentley gives Continental GT Speed even more power

The Bentley Continental GT Speed has never been accused of being a slouch when it came to power, bluntly incorporating the word Speed in its name, but it seems the company's engineers believe there is still room for improvement. And so for 2015 the Bentley Continental GT Speed and Bentley Continental GT Speed Convertible will receive a slight bump up in power, and will now offer 626-hp and 607 lb-ft of torque. That's up from 616-hp and 590 lb-ft of torque in the 2014 versions of this 6.0-liter W12 beast.
