Lexus GS 300h: Shanghai Motor Show

Offering much better economy than the GS 450h, it offers not only a viable alternative for private buyers looking for a bit of beautifully built Japanese luxury with lower running costs, but also makes the GS a much more appealing option for company car drivers – probably where most of the sales will be made. Lexus are aiming for Co2 emissions below 110g/km for the GS 300h (the IS 300h manages 99g/km) which will give headline economy around 60mpg – a third better than the GS 450h can manage. Power comes from the same hybrid drivetrain as the IS 300h, which means a 2.5 litre petrol mated to an electric motor and delivering 215bhp and o-62mph in around 8.5 seconds.

2014 Mercedes S Class: First interior photos

We have the first interior photos of the 2014 Mercedes S Class ahead of its debut in May 2013, showing a much more modern interior. But now, with a reveal of the new S Class just a couple of months off, we have the first photos of the interior of the new S Class showing a  car that keeps much of the layout of the current S Class but adds in more curves, more technology, a more modern look and a more upmarket feel than ever before. The cabin flows from the screen in to the doors in the same sort of seamless way it does an the Jaguar XJ – where it makes the cabin feel more spacious – the instrument panel is a huge digital display, the seats are differently contoured and trimmed, there seems to be more room, better lighting and an altogether more upmarket feel for Mercedes range topper.

Upgraded Ford MyKey blocks explicit satellite radio channels

Teenage radio listeners might have to look somewhere else besides the family Ford for the Playboy channel or Howard Stern. The new generation of Ford's programmable MyKey system will let parents block "explicit" radio channels on the Sirius/XM satellite service in their cars. That would cover Playboy's and Stern's channels, as well as more than a dozen music channels, such as rapper Eminem's Shade 45 and the hard-rock Boneyard.
