The Sportec SPR1 might look like just another 911 body kit package, with its histrionic spoiler and side skirts, grey rims and four-strong collection of tailpipes. However, strap yourself into this bad boy and you'll be greeted to the sound of 858bhp behind your lugs from a twin-turbo engine of as-yet-unknown capacity.

That's enough to ping the SPR1 to 235mph, a figure it clocked at Nardo in Italy. Mercifully it has four-wheel drive too, but to be honest that's about all we know for the time being, presumably because the maker wants to keep us hanging until its British debut at the Salon Privé in London on the 22nd July. That's at the Hurlingham Club in Fulham, if you fancy going.

Oh, there is the small matter of its £600,000 asking price, though that doesn't seem to have put people off too much - 60 percent of its 'limited' production run has already been snaffled.
