Mercedes' luxurious sports saloon

This is Mercedes' second-generation four-door coup, the CLS 500 BlueEfficiency. And it's a "very modern and appealing sports saloon indeed", says Matt Saunders in Autocar. It is five metres long and weighs nearly two tonnes, but the new stop-start automatic engine system and improved aerodynamics mean it is still capable of better than 30mpg while still developing 402bhp and hitting 62mph in under five and a half seconds.

The car is a "superbly quiet, comfortable and compliant machine" when you want it to be, and yet "accurate and willing" when you want to "stretch its legs". The electro-mechanical steering system is also "precise, responsive and direct". All in all, "Mercedes has pulled off something very special with this car" a saloon with dynamism, and all the refinements you'd expect from Mercedes.

The new cabin, which mixes a "simple but elegant console with top-quality materials", is a "supremely comfortable place to spend time", says Joaquim Oliveira in AutoExpress. And outside, the car looks "as spectacular as ever", with a more bold and aggressive appearance than its predecessor.
