It might not look like much, but this test mule could be proof that McLaren and Mercedes-Benz areb pushing ahead with their baby supercar.
Spied on one of the German car maker's proving grounds close to its Stuttgart headquarters, the aluminium spaceframed hack seemed to be performing installation tests. It could be a definite sign that the McMerc, labelled P8, has finally been given the green light.
Built to assimilate the mid-engined/rear-wheel drive layout of the proposed two-seater, the mule provides first tantalising clues to the eagerly-awaited Anglo German supercar, which is expected to carry the name SLS and go on sale before the end of the decade at a price, insiders hint, will pitch it in direct competition with the likes of the new Audi R8, Ferrari F430 Modena and Porsche 911 Turbo.
Set to run a heavily reworked version of Mercedes-Benz AMG division’s new normally-aspirated 6.2-litre V8 engine with up to 575bhp, the SLS has been conceived as a more affordable and more driver orientated car than the front-engined SLR, which was developed to a brief as the ultimate Grand Tourer.
