And because the standard engine management doesn’t have to support all these gizmos, Aston engineers have replaced it with a Pectel system that merely feeds and fires the engine – hence the 600bhp output, which improves on the production DBS by a cool 90bhp, and extends the redline from 6800rpm to 7600rpm.
Bearing in mind that the RS is 230kg lighter than the DBS, the claimed RS acceleration (4.0sec for 0-62mph, 0-100mph in 8.5sec) seems conservative. Our DBS test times were 4.2sec for 0-60mph (say 4.3sec for 0-62mph) and 0-100mph in 8.7sec.
What’s it like?
Step into the RS and you’ll find you sit lower than ever, with the base of the side windows more or less level with your chin. The modified DBS wheel is high and almost vertical in front of you, so you view corners over your knuckles, sighting directly down the long bonnet. The RS has a pair of firm and comfortable semi-race bucket seats by Recaro, trimmed in grey Alcantara.
The standard V8 instrumentation remains, but most of the dials don’t work. Instead, engineers have replaced their functions with a small data logger that presents engine rpm in digits and is topped by a row of gearchange lights that grows as revs rise.
“Change at three or four lights,” Craig Croot, Aston Martin's test driver advises. “That’s about 7000rpm. You’ll find the power as you get towards 7600.” Privately I doubt I’ll notice.
Beneath the yowl the V12 begins to deliver a full-throated roar as the accelerator gets into the second half of its travel. You’re thrust back in the seat, Silverstone's south circuit becomes narrower, kinks become curves. Straights are now short and I’m starting to see the shift lights. The engine sounds fantastic, whoop-cracking at every downshift. But there is no time to savour this. You’re concentrating on not arriving too fast at the next obstacle.
The brakes are phenomenal. They simply eliminate speed like nothing I’ve ever experienced, squeezing the car into the road and making you hang forward in the straps. I start leaving my braking later and later – until beads of sweat literally pop up on my brow – and yet I still discover so much retardation in hand that I wish I’d dived in another 100 yards later.
Should I buy one?
Yes, although your options are limited by decisions that are due to made at Gaydon this summer. At present Aston is looking at two production scenarios: either a super-exclusive run of 100 RS superlights, little different from this one and priced at around £150,000, or a run of 300-400 cars, with more equipment and a slightly lower price.
I find myself hoping they stick with the 100-off scenario. There are plenty of other powerful, plush Astons; let’s have a special one. For £150k you’ll get track-based performance that can rival the best from Ferrari or Porsche; you’ll also be getting the fastest Aston, and maybe the best ever built.
