Aston Martin DB11 arrives with 600 horsepower, stunning design

The drapes have been removed from the new DB11, billed by Andy Palmer, Aston Martin's chief executive, as "not only the most important car that Aston Martin has launched in recent history, but also in its 103-year existence." Well, they all are, Andy. Aston Martin is such a small company that it bets the farm with each new model. That's part of its appeal, for Aston's one constant is the svelte beauty of its cars, which (lest we forget) are the company wheels for one Commander James Bond. So the DB11 is important, make no mistake. It goes on sale this autumn and will cost $211,995 in the US. It's the tenth car (there was no DB8) in a lineage that began in 1948 with the DB1 – the first car to bear the initials of then owner, David Brown. Just 15 DB1s were made, but the DB line has been the most successful model for Aston Martin over the years, including such cars as the DB5 and DB7 as well as the 2003 DB9, which was the last all-new Aston Martin. This totally new DB11 is a clean-sheet approach from design director Marek Reichman, with a new aluminum bodyshell, suspension, cabin, and a Mercedes-Benz-based electronic architecture, which runs the systems.

The heart is a brand-new, 5.2-liter V12 boosted with two Mitsubishi Heavy Industries twin-scroll turbochargers with water-to-air inlet-charge coolers. It punches out 600 horsepower at 6,500 rpm and 516 pound-feet of torque from 1,500 rpm. Maximum speed is said to be 200 miles per hour with 0-62 acceleration in 3.9 seconds. The new engine drives the rear wheels via a ZF eight-speed automatic transmission and a mechanical limited-slip differential. Aston moved from the previous 6.0-liter naturally aspirated unit to a 5.2-liter biturbo to improve the part-load efficiency and EPA fuel economy figures. "In downsizing we want the emissions and we want the economy, but more than those, we want the torque," says Ian Minards, director of product development. To save fuel the engine will close down one bank and run as a 2.6-liter straight-six when the extra power is not required, but to prevent the exhaust catalyst from overcooling, the electronics switch between two banks. "It's undetectable," says Minards. Minards' team spent three years creating this car. "It's been a little bit daunting," he says.

Aston Martin DB11 V8 loses four cylinders but none of its grace

We love the Aston Martin DB11. Few vehicles combine speed, luxury, and comfort as well as that beautiful British coupe. That said, it's not the most efficient or affordable GT in the world, but Aston Martin is planning to change that. Starting this year, the company will offer the DB11 a twin-turbocharged V8 sourced from the mad Germans at Mercedes-AMG. We've known about the engine partnership for a while now, though we assumed the first Aston Martin to use a Mercedes-AMG V8 would be the next-generation V8 Vantage. At first, sticking a V8 under the hood might seem like an odd choice, but the DB series only recently started using V12s. Historically, the car has packed powerful inline-six engines. Offering two engines will allow the company to sell a lower-cost model and presumably boost sales. That means changes are strictly mechanical in nature. The engine is the now-common 4.0-liter twin-turbocharged Mercedes-AMG V8. Output is 503 horsepower and 498 pound-feet of torque. That's down 97 horsepower and 18 pound-feet of torque from the 5.2-liter V12. In the Mercedes-AMG C63 S, the 4.0-liter V8 makes equal horsepower and 18 more pound-feet of torque. Aston Martin says that the partnership with Mercedes-AMG allows the company to tailor the engine for Aston Martins. This means a new ECU with new engine and throttle mapping. Losing four cylinders changes the character of the car a bit. The DB11 V8 is a not-insubstantial 254 pounds lighter than the V12. Since most of the weight savings comes from behind the front wheels, Aston Martin says the V8 model is more agile than the V12 model. Engineers have adjusted the suspension bushing, geometry, anti-roll bars, springs, dampers, and stability control to account for the weight savings. The DB11 V8's diet helps offset the lower power output. As such, the 4.0-second 0-62 sprint is just 0.1 seconds off the V12. Top speed is down 13 mph to a still extralegal speed of 187 mph. We don't have fuel economy ratings for the US, but expect an improvement from the V12's current rating. The V8 will be available with all of the same equipment and trims as the V12, with just a few visual changes to distinguish the two models. The V8 gets unique wheels, darker headlight surroundings, and just two vents on the hood, available in either black or titanium. The DB11 V8 goes on sale in the US later this year. At $198,995, it undercuts the V12 model by $17,500.

Aston Martin values electric propulsion over downsizing

Not even small-volume manufacturers are being exempt from the automotive industry's pursuit of higher efficiency and lower emissions. At present, that means either electric propulsion (whether in part or in whole) or downsizing conventional engines, and for Aston Martin, the future apparently lines in the former. "I see in our future obviously V12s, V8s and probably battery-electric cars," Aston's CEO Palmer revealed to Autocar. "As time evolves, there's probably an inevitability to hybridisation, simply because, car by car, you can only downsize so much. I'd rather put a hybrid in there than an in-line four-cylinder." So just how does the company envision implementing electric or hybrid propulsion? "Imagine something like a 4x4, 1,000-bhp silent Rapide. I think 'Power, Beauty, Soul' doesn't say it has to be a gasoline engine. It just needs to be really powerful, really beautiful and set your heart on fire," Palmer explained. "I'd argue that 1,000 bhp on the ground would probably do that for you. So that's the route we could go." The British automaker demonstrated the DBX concept with an all-wheel-drive electric powertrain at the Geneva Motor Show a few months ago, and is currently in the process of revitalizing and expanding its current product range. Of course Aston isn't the only high-end niche automaker faced with the decision to either downsize or add hybrid propulsion. Ferrari is taking both approaches, using smaller turbocharged engines in its V8 models and moving towards hybrids with its V12s. Porsche offers an array of plug-in hybrids and is in the process of downsizing and turbocharging its naturally aspirated engines. Pagani switched from a big V12 in the Zonda to a smaller turbo V8 in the Huayra. Bugatti is expected to use electric turbochargers in its Veyron successor. And Lamborghini was recently reported to be considering a turbo five for the Huracan.
