Aston Martin and Mercedes-AMG formalize technical partnership

The development of a partnership between Mercedes-Benz and Aston Martin has been a long time coming. The news dates back to 2008, and over the five years since was supposed to lead to a rejuvenation of both the Maybach and Lagonda brands. That program ultimately fell apart, but the tie-in was forged afresh in July when the two automakers signed a letter of intent over a renewed partnership. And now that partnership has been formalized.
In a deal just announced, Mercedes-AMG will build a new V8 engine for Aston Martin that will power a new generation of luxury GTs for the British marque, presumably to replace the 4.7-liter V8 in the Vantage. The relationship appears to be similar to the one already in place between AMG and Pagani, only in this case, will involve Daimler taking as much as a five-percent stake in Aston Martin and an observer seat on Aston's board.
The technical partnership is also set to lead to the supply of electric and electronic systems, and could incorporate "additional areas of cooperation in the future." Whether that will include a fresh attempt at reviving Lagonda remains to be seen, as does the future of Aston's long-serving, Ford-based 6.0-liter V12 engine. But for now you can read the full announcement below.

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 updates Vanquish, Rapide S for 2015 [w/videos]

For such a small company, Aston Martin certainly keeps busy. Having already previewed its new V12 Vantage S Roadster ahead of its Pebble Beach unveiling, the British marque recently confirmed the arrival of a new Lagonda super sedan. But now it's turning its attention to its two flagship production models with a series of upgrades. The enhancements to the 2015 Vanquish (both coupe and Volante convertible) and Rapide S sedan center around the inclusion of the new Touchtronic III eight-speed automatic gearbox that brings with it enhanced performance, efficiency and comfort. Along with reprogrammed Bosch electronics, the new transmission and updates net a 3-horsepower boost in Vanquish (bringing output up to 568 hp) and 2-hp boost in Rapide S to 552. Torque rises to 465 pound-feet in both, along with revised stability control and steering systems. Upgraded dampers on the Vanquish are 15-percent stiffer up front and 35-percent firmer in the rear, while the Rapide S gets larger front brakes. The result of this suite of minor updates results in a rather substantial performance boost. According to Aston, the upfittings cut a good half-second off the 0-60 sprint for both models: the Vanquish drops from 4.1 seconds to 3.6, and the Rapide S from 4.7 seconds to 4.2. Additional visual enhancements to differentiate the new models are limited to new wheels, paint options and interior trim, the details of which you can scope out in the press release and pair of videos below. DYNAMIC ENHANCEMENTS FOR ASTON MARTIN VANQUISH AND RAPIDE S - Acceleration, top speed, emissions and economy improve significantly - Debut of state-of-the-art eight-speed Touchtronic III automatic gearbox - New engine management system, enhanced trim and specification options 6 August 2014 - Aston Martin is today revealing details of a raft of important enhancements to two of the brand's most popular and successful sports cars: the Vanquish ultimate GT and Rapide S four-door, four-seat, sports car. With the arrival of 15 Model Year (15MY) cars in markets around the world over the next few months, the luxury British brand is offering not only considerably enhanced performance and much-improved fuel economy and emissions, but also an even more honed, precise and responsive driving experience.
