The information surrounding the new supercar is sound, considering that Mercedes originally tapped the engineering firm in 2004 to produce a less expensive alternative to the SLR. The mid-engine prototype – codenamed the P8 – was put on hiatus after some financial and quality woes hampered Mercedes' forward momentum, combined with the less-than-stellar reception of the P8's big brother. In short, Mercedes was pissed and didn't want to explore future projects with McLaren.
Although we've always taken Autocar's pontifications about as seriously as our local read through the supermarket tabloids, they claim to have sources within McLaren that says the F2 has been testing around the company's Woking headquarters, wearing Ferrari 360 bodywork. Time will tell, but in the meantime, watch out for Batboy.
