Chris Harris pits Aston GT12 vs 911 GT3 RS vs McLaren 650S

The Geneva Motor Show is never lacking in exciting performance machinery. And this year was no exception. Our eyes, like those of Chris Harris, were drawn by two hardcore, track-focused versions of existing sports cars. Both wore the name GT3, and now Harris has brought them together for a supercar shootout. And he's thrown one more in for good measure. Those natural rivals are the Aston Martin Vantage GT12 and Porsche 911 GT3 RS, the latter manufacturer having pressed the former to drop the GT3 name to which it claims exclusive domain. There's a great deal that separates them, of course: one's got a V12 up front, the other a flat-six way in the back. But what binds them together is a common approach of taking an existing model, stripping it down, and tightening everything up to make it more of a weapon than a grand tourer. What that means in the Aston's case is a rather high price tag, much higher than that of the Porsche. But scarce demand and speculation on the open market have left British customers, at least, paying as much for the GT3 RS as for the limited-edition Aston. And that takes both into proper supercar territory. So to show what else that kind of money can get you, Monkey has brought along a McLaren. Not the similarly track-focused 675LT, but the standard 650S... Spider, no less, and with worn hard rubber. So which one performs best on the road? Which clocks the fastest lap time on the track? And which gets Harris' vote? You'll have to watch the video for yourself to find out, but it's well worth the 25 minutes of your lunch break.

Porsche resurrects V8-powered 911 prototype from the Eighties

These days, we take it for granted that the Porsche 911 uses a flat-six engine. That's because every version of the iconic rear-engined sports car has had one. Right? Well, for the most part. There was the 912 that joined the original in the late Sixties with a flat-four. And in the mid-Eighties, Porsche toyed around with the idea of a V8-powered 911.
After the first-generation 911 had been in production for over two decades, Porsche began development of its successor, the 964, in the 1980s. And one of its ideas was to use a V8 engine. So it took a 964, borrowed a V8 from Audi, gave it the rear bodywork from a 959 and dubbed it the 965.
The idea was to create a more affordable successor to the 959 that included its advanced all-wheel drive system and active suspension. The Audi V8 would have been replaced with one of Porsche's own design - possibly based on the it had built for Indy racing - but Dr. Ulrich Bez (who was then head of Porsche R&D long before taking the reins at Aston Martin) ultimately killed the project.

Are you the 2017 Porsche 911 GTS Targa?

Our spy shooters have caught a strange, mash-up beast wearing a Porsche badge. Superficially, this is a facelift for the 911 Targa that features new bumpers, door handles and a redesigned engine cover, along with new light graphics for the front and rear lights. But have a look around back, and you'll find two inboard exhaust pipes; they aren't right up against each other as on the 911 GT3, but are spaced about five inches apart. The shooters said the first time they saw that arrangement was last winter, on a convertible during testing. We saw it again more recently in spy shots of what was thought to be the 911 GTS coupe prototype at the track. But when the production GTS arrived, it wore the traditional quad-pipe at the corners. The theory put forward by the spy photog: the current GTS has a naturally aspirated engine, but facelifted prototypes they've been seeing all have turbo engines, so this could be the facelifted Targa coming in 2017, after the 991-model 911 gets a refresh. In that case, the GTS coupe prototype at the track would have also been a post-refresh, turbo-engined GTS. It's only a hypothesis, but more than one outlet has reported that Porsche is going all-turbo for the updated 2015 models – the new exhaust position and those 911-Turbo-like vents could be their identifiers. We expect to find out when the lineup is unveiled at the 2015 Geneva Motor Show, possibly codenamed 992 instead of 991.2.
