Listen to the Aston Martin Vulcan do what it was meant to

What happens when a world-class sports car manufacturer and racing team is permitted to design a vehicle from the ground up with no rules to follow? Something along the lines of the Aston Martin Vulcan, that's what. Built neither for the road nor for any racing series, the Vulcan is part of a new class of dedicated track cars. And as you can see from this latest video, it's all but completely unhinged. The Vulcan represents Gaydon's answer to the likes of the Ferrari FXX K and McLaren P1 GTR. It packs a 7.0-liter naturally aspirated V12 at the front of an aluminum chassis with carbon-fiber bodywork. It weighs less than 3,000 pounds, but packs 800 horsepower – without a hybrid system or turbo spool in sight. In short, it's takes the best from Aston's road cars and its race cars, amps them up to 11, and abides by none of the rules they need to. Apart from some preliminary teasers, a run up the hill at Goodwood, and a brief (but static) encounter with its Cold War, airborne namesake, this represents a rare opportunity to see – and most importantly hear – the Vulcan do what it's designed to do. With only 24 to be made and each priced at over $2 million, this may be the closest you'll ever get. So go full-screen and crank the speakers to enjoy the unbridled show.

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 CEO calls Tesla Model S 'Ludicrous' mode stupid

To be fair, some would say paying as much as a quarter-million dollars for a car in itself qualifies as "ludicrous." But the CEO of Aston Martin, a company that is readying a pricier electric-vehicle competitor to the Tesla Model S, didn't mince words in discussing Tesla's newest gizmo that can propel the sedan from 0 to 60 miles per hour in less than three seconds. In fact, Andy Palmer, Aston's CEO, prefers a slightly more balanced approach. Palmer was quoted in Automotive News as saying that Tesla's Ludicrous Mode was "stupid." He added that he'd rather have an electric vehicle that could last "a few laps of a decent race course" instead of one that does its best imitation of a Dodge Challenger Hellcat. Palmer also took to his Twitter account to note, among other things, that the Aston's "insane mode comes as standard - no button required." Aston Martin said earlier this week that it planned to make a battery-electric variant of its Rapide Sedan. That model will have 800 horsepower as well as a 200-mile single-charge range. The car will also cost between $200,000 and $250,000, or about twice the cost of a top-of-the-line Model S. As for the Tesla, its Ludicrous mode was announced last month for the Model S and it will eventually be added to the Model X for those who are big on flipping SUVs. Tesla said that the feature cuts the sedan's 0-60 mpg time to a tidy 2.8 seconds, though the option does cost about $10,000. Which is probably about the price of an Aston Martin door handle.
