Illustrations: Mercedes/McLaren SLS in the works?

Mercedes and McLaren are planning to sell as many as 2000 "SLS" sports cars a year to rival the likes of the Ferrari F430, Lamborghini Gallardo and the V10 version of Audi's R8, according to the insiders at Brenda Priddy & Company. Although McLaren engineers are remaining tight-lipped about the project, sources say feasibility studies are currently being carried out on the car at one of Mercedes' secret test centers in Germany.

McLaren is hoping to use carbon fiber construction for the new car, although there are doubts about the economic viability of using the material for a car with a projected price tag of about 150,000 Euros.

Sources wouldn't be budged on whether the new car, thought to be code-named P8, will have a three-seat arrangement similar to that of the F1, but equally our source doggedly refused to confirm the new car as a conventional two-seater. One possibility is that the third seat would be mounted centrally towards the rear, the reverse of the F1's layout. It will be mid-engined though, partly to make it distinct from the front-engined Mercedes SLR McLaren. Gallery after the jump...
