Aston Martin previews new 5.2-liter twin-turbo V12

Depicted in the teaser video above is Aston Martin's new 5.2-liter twin-turbocharged V12. Beyond those basic specifications, Aston isn't saying much about this new engine or what it will power, but it does promise that the new engine will debut sometime this year. The bulk of Aston Martin's current lineup – basically everything but the V8 Vantage – is powered by a 6.0-liter V12 that dates back to the DB7 Vantage that debuted in 1999. Only where that model produced 420 horsepower, the latest version in the Vantage GT12 produces nearly 600 hp. Which just goes to show how much Aston has been able to do with the aging engine, but everything has its limits, and all good things must come to an end. While the switch to forced induction may mean a less revvy engine, it ought to deliver more torque (as well as lower emissions and fuel consumption). Aston has a new partnership with Mercedes-AMG that is slated to supply the British automaker with a twin-turbo V8. But the German outfit has considerable expertise with twin-turbo V12s as well. The production facility that recently relocated from Affalterbach to Mannheim produces the 6.0-liter twin-turbo V12 that motivates Mercedes' own SL65 roadster, G65 sport-ute, and S65 sedan, coupe, and cabrio, as well as the version for the Pagani Huayra.

Aston Martin-Red Bull 001 details: 175 units, $3M, 0-200-0 in 15 seconds

The Aston Martin AM-RB 001 is starting to sound like it will be the most extreme hypercar ever made. We're basing that on a series of new comments made by Red Bull Racing's resident aerodynamic genius and chief technical officer, Adrian Newey, in an interview with The Wall Street Journal's Dan Neil. Newey shared many interesting nuggets, so we'll try to provide a simple summary of how frighteningly potent the AM-RB 001 is. The new hypercar should hit 200 miles per hour in around 10 seconds, while a massive set of brakes will cut that speed to zero in half the time – in other words, zero to 200 to zero in just 15 seconds. That kind of stopping power sounds physically painful. Certain versions of the 001 will make up to 4,400 pounds of downforce, and if that's not enough to keep the car pasted to the pavement through 4G bends, Newey hinted that the active suspension will rely on the ground effect more than any other car. "I studied aero at the University of Southampton," Newey told Neil. "My final-year project in 1979 and '80 was on ground-effects aerodynamics applied to road cars and sports cars." Beyond the performance stats, Newey verified some of the broader questions about the 001's availability. For one, Aston Martin and Red Bull will build 175 examples of the potentially record-breaking hypercar, with 150 designated for road use and another 25 limited to the track – they're the ones that will enjoy the 4,400 pounds of downforce and full-on 4G cornering ability – so the chances you'll ever encounter a 001 in the wild are almost nil. And buying one? Plan on spending at least $3 million. Newey, along with Aston Martin Chief Designer Marek Reichman and Project Engineer David King, reveal more about the 001 in the piece, including some of the philosophical and design principles behind a $3M hypercar. It's very much worth a read, if you can get around the WSJ's pay wall. Related Video:

Episode 2 of The Grand Tour will feature knives, explosions, guns, and also cars

Following an immensely successful debut, The Grand Tour will follow up its first episode with exciting, dangerous things. Based on the trailer above, the episode will start peacefully enough with the trio driving up to the tent in South Africa with a convoy of off-road trucks. However, it seems each segment will be much more exciting. Right at the start of the trailer, there are clips of the Aston Martin Vulcan, a 7.0-liter, 820-horsepower V12 supercar, which will likely be the car tested at the "Ebola-drome" this week. Of course the car is communist because it doesn't have a V8. Then things get steadily more dangerous through the trailer. James May is shown as a somewhat unwilling participant at some sort of drifting exhibition. He apparently doesn't like tire smoke in the evenings. We also see that the trio went to Jordan for another segment. This is when we get a glimpse of Richard Hammond playing with large knives. Immediately following are clips of some sort of car chase challenge with large SUVs and luxury sedans, during which James May shoots an assault rifle out the back of an Audi S8. The shooting results in big explosions. It's worth a look yourself, to get in the mood for the next episode which hits Amazon on Friday. Related Video:
