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.

BMW Z4 M Sport Package released

BMW is to debut the M Sport Package for the Z4 at the Detroit Auto Show Back in September we brought you some pictures of what at first glance appeared to be a BMW Z4M, despite BMW making it clear that they are not going to build an M car this time round. But it actually turned out to be a Z4 with M Sport Package zapping round the Nurburgring looking, to all intents and purposes, like a new hot Z4. Almost three months on BMW has finally got round to revealing the M Sport Package for the Z4 which will – just like the BMW Z4 sDrive35is we reported on yesterday – debut at the Detroit Motor Show in  January 2010.

Bentley celebrates 95 years with Mulsanne 95

Bentley is celebrating its 95th birthday with a special-edition Mulsanne 95, which will only be available in the U.K. Only 15 examples of the Mulsanne 95 will be produced. The upgrades are purely visual, which means power still comes from 6.75-liter twin-turbo V8 making 505 hp and a cement-cracking 752 lb-ft of torque.
