Mercedes and McLaren are preparing to head their own separate ways for the next batch of supercars – including the Mercedes SLC, SL65 AMG Black Series and McLaren P11 – but not before one last hurrah. Emerging reports from Germany indicate that the two companies, which are anticipated to continue collaboration on the race track, will soon unveil one last special edition of the SLR before the controversial supercar speeds off towards the horizon and into the setting sun.

The final iteration of the SLR is reported to be a lightweight speedster with neither roof nor windscreen, just a small deflector. Thanks in part to the removal of air conditioning and power windows (neither of which are needed when you don't have a roof anyway), curb weight has been trimmed by about 200 kilos (approximately 440 pounds), and promises to rip your head right off with a top speed of 350 km/h (217 mph), some 13 km/h over the previous top-dog SLR 722's maximum velocity. Only 75 examples will be produced, at a price of €450,000. Oh, and Lewis Hamilton is said to have something to do with the project, which is inspired by the legendary 1955 300 SLR Silver Arrows. Stay tuned for more details, with initial images reportedly due to surface tomorrow.
