This comes off the back of a good year for Mercedes in America, where sales have risen by 14 per cent and almost one in five luxury vehicles sold has a three-pointed star on the front. In other Mercedes news, this year’s GLA 45 AMG debuted complete with what it is claimed to be the world’s most powerful four cylinder engine (355bhp from 2.0 litres). Small wonder the car comes with four-wheel drive as standard. For dictators and plutocrats, the new S600 is yet more powerful than its predecessor (523bhp and 612lb ft of torque from the V12 twin-turbo engine), but mother earth can rest easy as it comes with a stop/start system as standard – Combined fuel consumption is 25.4mpg, which is 21 per cent better than the outgoing model. -Telegraph
