Aston Martin confirms 3.0-liter turbocharged V6 for Valhalla

When the Aston Martin Valhalla hits the scene in 2022 (hopefully), it will be powered by an all-new 3.0-liter turbocharged V6 engine that will be fortified and electrified in a hybrid configuration that we don't yet know much about. Interestingly, Aston Martin says the V6's hybrid element will be tuned and sized for each specific vehicle in which it's installed. In the Valhalla, the dry-sump engine will be mounted directly behind the passenger compartment, and its so-called 'hot V' design will allow for relatively compact dimensions. And compact also means lightweight — the automaker says the complete engine weighs less than 440 pounds. Just the fact that the British automaker is investing the engineering effort to produce a new engine is significant. The company hasn't engineered its own in-house powertrain since 1969, when Tadek Marek's 5.3-liter V8 engine found its way under the hood of Aston Martin's aptly named DBS V8. The new 3.0-liter V6 is codenamed TM01 in Marek's honor. With that in mind, we expect this powerplant to serve in various Aston Martin models for a number of years. We look forward to further details in the future, especially the all-important horsepower and torque figures. In the meantime, feel free to peruse the high-resolution image gallery above, where you'll see intricately milled castings along with the engine undergoing dyno testing and running red hot with the lights down low.   Related Video:

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:

2018 Aston Martin DB11 AMR Review | A private world of comfort and speed

There are moments when miniscule adjustments to something wonderful can yield unforeseen enhancements. The addition of a dash of Maraschino liqueur to a perfect Manhattan. The application of a few Newton-meters more pressure in a deep tissue massage. Gold-plating the wire wheels on your Commodore Blue Continental Package-equipped 1985 Cadillac Eldorado Biarritz Convertible. So it is with the Aston Martin DB11 AMR, a slight tweak to the Aston Martin DB11 V12 — already one of our favorite grand tourers. The non-AMR DB11 hosts the ideal combination of profligate luxury, recherche exclusivity, and muscular performance. (The V8 is also ... fine.) But Aston Martin's new AMR performance sub-brand has drizzled its speed effluent onto the DB's componentry and software. The result borders on transcendent. AMR was launched at the Geneva Motor Show in 2017 as the storied British marque's go-fast subsidiary (its M or AMG, if you will). Inspired in name, if not in mission, by the Aston Martin Racing team, it has already resulted in the AMR-ization of a half-dozen Aston vehicles including iterations of the Rapide, Vulcan, Valkyrie, and previous-generation Vantage. The $241,000 DB11 is the seventh in that series, and it will take the place of the "base" DB11 V12 when it appears in the states later this summer. Since Aston recently opened the first of its fancy-pants AMR Performance Centers adjacent to Germany's famed Nurburgring racetrack, it seemed fitting that our test drive of the new car commence there. We snagged the DB's crystal-tipped key fob and spent a couple days tearing everywhere in the Rhineland region that wasn't the "Ring," including narrow wending mountain roads, expertly paved two-lane byways, and unlimited Autobahn uber-highways. AMR's sorcery has, as noted, yielded relatively small changes on paper. The twin-turbocharged 5.2-liter 12-cylinder now makes just 5 percent more horses, for a total of 630. The dampers and springs have been stiffened by about 10 percent, the anti-roll bars front and rear by half that and half again. More rigid engine and transmission mounts have been added for greater stolidity. The transmission has been remapped for increased differentiation across the GT, Sport, and Sport Plus driving modes, selectable via a switch on the right side of the steering wheel.
