Mercedes GLA goes subterranean

FOR SUV owners looking to test their cars’ off-road credentials, the obvious place to put them to the test probably isn’t nearly 200 metres underground. But that’s exactly where the new Mercedes GLA found itself as it descended into Winsford Rock Salt Mine, 620 feet beneath the Cheshire countryside. The working mine, which supplies much of the UK’s gritting salt for wintry roads, played host to four standard (apart from extra driving lights) GLA models, which were lowered down into the mine nose first before being let loose in the 130-mile network of tunnels.

New Mercedes S 63 AMG costs from £119,565

New Mercedes S 63 AMG (pictured) costs from £119,565 The arrival of the new Mercedes S-Class in May saw MB move their range topper on properly for the first time in almost a decade, but with UK prices staring from £62,650 for the S 350 BlueTEC it wasn’t going to be on most people’s shopping list. And if you can’t afford Mercedes’ entry-level S-Class there’s no hope of affording the new S63 AMG, which Mercedes has revealed will cost an eye-watering £120k when it arrives in the UK in November. To be entirely fair, the new S63 is an awesome car with immense performance (which would be even more impressive if Mercedes endowed it with 4WD, as they do in other markets) with its 5.5 litre bi-turbo V8 developing 577bhp and getting the S63 to 62mph in 4.4 seconds.

This is a heady title: highest specific output of a General Motors production engine. Ever. Better than any Corvette, Cadillac or Camaro or anything else GM has produced in the last century.
