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.

Aston Martin gets to work on DB9 successor

Introduced over a decade ago, the DB9 is by now the oldest model in the Aston Martin lineup. It predates the arrival of the V8 Vantage, outlasted the Virage and DBS that spun off from it, and outlived the One-77, V12 Zagato and Cygnet that have all come and gone over the length of its tenure. But soon the current DB9 will be retired. In its place, we're looking forward to an all-new model to spell the beginning of the end of Aston's long-serving VH architecture and restrict the ubiquity of the 6.0-liter V12. In their place, as we well know, the DB9's successor will be based on an all-new aluminum platform and be powered by a 4.0-liter twin-turbo V8 to be furnished by Mercedes-AMG. Though AML insists that the engine is being developed by both parties and built by AMG to Aston's exact specifications, Autocar reports that it will be the same unit being developed for Mercedes' own models, with modifications limited to ECU, exhaust and possibly turbo boost, but with no internal modifications. Even as-is, the engine is expected to produce almost as much power as the DB9's current V12 but a bit more torque – which, combined with the lower weight, ought to make Aston's new core GT quicker than the one it will replace. Rather than using the new eight-speed automatic introduced for the latest twelve-cylinder Vanquish and Rapide S, the current DB9 is expected to continue using the old six-speed slushbox until its replacement goes with Mercedes' new nine-speed unit. Expect a step forward in styling but with familiar Aston cues, potentially previewed by the Zagato one-off pictured above and the new Lagonda sedan, when it arrives in 2016. The big question is what Aston will call the next-gen DB9. It skipped the DB8 when naming the replacement for the DB7 – ostensibly to show how big a step it was, but probably also to avoid confusion over its cylinder count. We couldn't imagine Aston going backwards in its naming scheme, but whether it sticks with DB9, moves on to DB10 or jumps to DB11, one thing's for sure: it will definitely carry the initials of the company's former president David Brown. When reached for comment on the development of the DB9 successor and what that would mean for the future of the V8 Vantage, Aston Martin spokesman Matthew Clarke told Autoblog: "Part of our agreement with Mercedes is specifically for V8 engine development but never have we anywhere made any comment as to where such engines would or wouldn't be used."

Ford GT dominates Le Mans qualifying, gets slapped with performance adjustment

Fifty years after Bruce McLaren and Chris Amon drove the Ford GT40 to victory at the 24 Hours of Le Mans, Ford is poised for a historic return to the Circuit de la Sarthe. The new Ford GT took the top two qualifying positions in the LMGTE Pro class, and four of the top five. Ferrari's 488 filled in the rest of the spots in the top seven, the first two from AF Corse. In other words, we're primed for a reboot of the classic Ford-Ferrari feud at this year's race. Or not, as the ACO, which organizes the 24 Hours of Le Mans, announced sweeping pre-race Balance of Performance (BOP) adjustments this morning that make this year's GT class anybody's race. In LMP1, last year's overall winner Porsche locked up the top two spots with the 919 Hybrid and will lead the entire field at race start. Toyota's two-car factory effort followed with qualifying times 1.004 and 2.170 seconds behind the pole lap. Audi rounds out the manufacturer-backed LMP1 class in fifth and sixth. Full qualifying results can be found here. The storyline for the GT cars is perfect - some say too perfect. Ford's class-leading times came after BOP adjustment to the Corvette Racing C7.R before qualifying. BOP is intended to level the playing field in the class by adjusting power, ballast, and fuel capacity. (Check out this explainer video for more, or even just if you love French accents.) But the process is riddled with unknowns and ripe for accusations of sandbagging. That is, if the Ford cars were intentionally slow in practice they could hope for BOP adjustment to improve their race chances. On the Corvette side, last year's GTE Pro winner went from the top of the field to the bottom, barely improving from practice to qualifying. If you think Le Mans is as rigged at the NBA Playoffs, well, it's not that simple. Because if Ford and Ferrari held back until qualifying - the eighth-place Porsche 911 RSR is three-and-a-half seconds off the class pole time - it was a pretty dumb strategy. This morning, the ACO tried to put things back in order by limiting the boost in the Ford GT's twin-turbo V6 and adding 11 pounds of ballast. Ferrari was also given extra weight but allowed more fuel capacity. The Corvette and Aston Martin teams were both given breaks on their air restrictors, which will allow their engines to make more power. Both Ford and Porsche also received extra fuel capacity.
