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 working on mid-engine Valkyrie ‘brother’ to rival McLaren P1

We know about the Aston Martin Valkyrie and the Valkyrie AMR Pro (pictured). And we know Aston Martin is planning a mid-engine rival for the Ferrari 488 and McLaren 720S. Now Autocar reports that the English luxury maker is working on yet another mid-engine model, a hypercar to outdo the McLaren P1 and Ferrari LaFerrari and stand up to the coming McLaren BP23. The newest addition to the small carmaker's grand plans is said to be known internally as "brother of the Valkyrie," and came about because of the sellout success of both the Valkyrie and Valkyrie AMR Pro. Both "brother of Valkyrie" and the 488 competitor are expected to use a carbon monococque with aluminum subframes. Both will use lessons from Aston Martin's tie-up with the Red Bull Formula 1 team, especially in packaging. Both are due to hit the market around 2021. And both will be products of the carmaker's Performance Design and Engineering Centre, a base of 130 engineers set up at Red Bull F1's Milton Keyes headquarters. However, the former car will fight in the GBP1M-plus price bracket ($1.4M-plus) where various manufacturers have made amazing hay with warp-speed daily drivers, and will be a limited edition "in order to add to its desirability." We remain in the dark on powertrains for both cars, but outsiders expect both to use a V8. When it comes to the "brother" car, Aston Martin's working relationship with Mercedes-AMG means it could tap the 4.0-liter V8 used by the DB11 and the Vantage. Apparently that engine can be wrung out to 800 horsepower with help from an ultimate EQ Boost setup. That still wouldn't be enough to compete in the segment, though, so the "brother" could become a demonstrator for Aston Martin's electric know-how — a rolling showcase that could turn its halo light on a potential electric sports car. Or perhaps there's another option that turns to Cosworth, the company helping develop the 1,000-hp 6.5-liter V12 in the Valkyrie. Aston Martin boss Andy Palmer wouldn't say much more about the junior supercar powertrain than, "In our portfolio today, we don't have an engine capable of giving us the output we require.

Aston Martin DB9 successor makes one sexy mule

It's been a dozen years since Aston Martin first introduced the DB9 to the world, and while it has undergone numerous revisions and updates over the course of its lifetime, twelve years is a long time. Fortunately the British automaker is preparing to launch a new version, and that's just what our shooters in Eiffel have spotted running around the Nurburgring. Now it's hard to tell much from these spy shots, because the prototype they depict is mostly wearing the bodywork of the existing DB9. So all the interesting stuff is happening beneath the skin. But it does appear that the front end is wider, giving the next-generation model – whatever it will ultimately be called – a wider front track and more room in the engine bay. Those who've been following the news will know that Aston has signed a deal with Mercedes-AMG that will see the German automaker's performance division supply it with a new powerplant, but that's not expected to be ready for the DB9 successor's arrival. Look for it to pop up in production guise sometime next year, then, with an evolution of Gaydon's long-serving and ubiquitous 6.0-liter V12 engine that's already developing 592 horsepower in the Vantage GT3... excuse us, Porsche: "GT12."
