Cosworth briefly crows that Aston Valkyrie's 6.5L V12 has record horsepower

It's only natural that Cosworth would want the world to know that it's building the world's most powerful naturally-aspirated engine for the Aston Martin Valkyrie and Valkyrie AMR Pro. The timing of when the world should know about it, that's at issue. Yesterday the English engine maker's official Twitter account posted a picture of the barely-there coupe and the line, "We're famous for breaking records and our latest engine, the Aston Martin Valkyrie 6.5-litre V12, will be the world's most powerful naturally aspirated road engine with 1,130bhp." Two tags accompanied the post, #Cosworth and #AstonMartinValkyrie. About 90 minutes later, the tweet disappeared. The likely issue is that Cosworth got ahead of Aston Martin's official confirmation of Valkyrie outputs, something we're more used to from patent offices and Chinese model makers. The question is what output is Cosworth really talking about, and which car. All of last year, however, various reports had the street-legal Valkyrie making 1,130 hp. A Road & Track report attributed "nearly 1,000 hp" coming from the NA V12, the remaining 130 from a kinetic energy recovery system working the front axle. Hence, we're not sure if Cosworth's talking about its own engine alone at 1,130 hp, or its engine with the KERS. But then there's this: At the launch of the Valkyrie AMR Pro during the Geneva Motor Show this year, Aston Martin said the track-only Valkyrie AMR Pro would enjoy "a combined power output of more than 1100 bhp — more than the Valkyrie road car and a figure than comfortably exceeds the magic 1:1 power-to-weight ratio." The truth's a mystery for now, which is just as Aston Martin would want it. If Cosworth's engine really does make 1,130 hp on its own, that would be monstrous, and it would mean the automaker's been playing a serious game of English understatement. Even if Cosworth included the hybrid help, however, an NA V12 with 1,000 ponies would take the crown. The only competition is the 6.5-liter V12 in the Ferrari 812 Superfast, and that's 211 horses adrift. The quad-digit figures expected from Mercedes-AMG Project One and McLaren Speedtail require turbochargers, as does the just-teased V8 going into the Shelby Tuatara. With the first of 150 Valkyrie road car deliveries scheduled for next year, we probably don't have that much longer to wait to find out. Related Video:

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."
