2013 Nissan GT-R and 2013 Alpina B6 mix it up on track and street

Here we have Autocar making an unforeseen comparison: the Nissan GT-R against the Alpina B6 at Brands Hatch and on public roads. Steve Sutcliffe clobbers the circuit in the 3,828-pound, all-wheel-drive sports car, then sees how well the 4,114-pound, rear-wheel drive grand tourer does against it.
Sutcliffe says there are quite a few similarities between the two cars, but that's really only on the spec sheet. The Nissan's got two turbos attached to its 3.8-liter V6, 542 horsepower and 465 pound-feet of torque. The Alpina's got two turbos attached to its 4.4-liter V8, 532 hp and 528 lb-ft. But one's brief is to be a monster on the track, the other on the boulevard, and if there's anything the video demonstrates, it's each car's focus.

BMW M4 Convertible spied with naked top and trunk

Our trusty spy photographers have been at it again, snagging these first images of the forthcoming BMW M4 Convertible without camouflage on its retractable roof and rear deck. You'll recall that this is not the first time we've seen the followup to the M3 Convertible, but that the last batch of images we had were encumbered by a lot more camouflage - this car is virtually naked by comparison.
Not surprisingly, the M4 looks to share its folding hardtop design with the standard 4 Series droptop, and it should operate in a similar manner as well. It's no surprise, but it looks like BMW is going to try and make the transition from M4 Coupe to M4 Convertible as effortless as previous efforts converting the M3 to an M3 Convertible. That should mean that below the beltline, this car is nearly identical to the coupe we saw in Detroit.
As for the camo'd features on these spy photos, the hood, front fascia, rear fascia, quarter panels, side sills and mirrors have all been shown on the M4 Coupe, and don't really bear mentioning. There's been no word of just where the M4 Convertible will make its debut, although considering the lack of disguise on this car, Geneva seems like a likely destination.

BMW M6 amped up for track duty by Risden

Risden Engineering is a bit of an unknown, if we're being completely honest - we have yet to report on the company to date, and its corporate website is really an information desert save for the name and a few email addresses. Even the press release that we requested from Risden's contact person is short and vague. That's all pretty much okay with us as long as the shadowy tuners, you know, make good on this sweet-looking BMW M6 racecar thing.
Dubbed the Risden 6R, we're told that the M6 modification will result in a vehicle that is more adept at track work, while still being street-legal. In terms of specifics, we read that a full aero kit will be involved, with one fixed and one retractable rear wing (hard to miss). There are obviously new wheels, and the company has also added a fully adjustable suspension, a four-point roll bar and a new braking system - all while reducing curb weight overall.
Apparently more details are to follow after the 6R's official release in the first quarter of 2013. We wait with bated breath.
