Tesla Model S squares off against Aston Martin Rapide S

Can the Tesla Model S electric motor's 443 pound-feet of torque from zero rpm and equivalent of 416 horsepower trump the Aston Martin Rapide S V12's 457 lb-ft from 5500 rpm and 550 hp? Autocar attempts to answer that question by drag racing them - which only leads us to ask more questions. Which is the fastest around a race track? Is the Tesla's relatively low top speed of 130 miles per hour (the Rapide S can reach 190 mph) forgivable in light of its astounding torque? Does that even matter?
We hope Autocar's Steve Sutcliffe will pit the Tesla and the Aston Martin against each other again in the near future to answer those questions, and pick once and for all which one is the preferred luxury sedan. But until then he entertains us in the video below by raving about the Model S's attributes, pitching it into medium-speed sweepers and getting it a bit sideways with nothing but road and tire noise permeating the cabin - something people in the UK can experience for themselves once right-hand-drive cars go on sale there this spring.

AMG's partnership with Aston Martin won't extend past engines, for now

There's been talk of late about the technical partnership between Aston Martin and the AMG division of Mercedes-Benz going beyond engines to include Mercedes sports car and SUV platforms for the English brand, perhaps as a way to kickstart the development of a Lagonda SUV. But AMG CEO Tobias Moers, speaking to Top Gear, said that's effectively out of the question because, "No one has the time to discuss any more involvement than that for now."
Moers believes Aston Martin will be so busy "for the next two to three years" integrating its AMG-sourced engine and electronics that it won't have the resources to devote to working out a platform-sharing deal; Daimler sources have already said that Aston Martin's development budget "just isn't enough" to even consider a whole new model, and that greater cooperation would require something like a larger ownership stake in the boutique sports car maker.
AMG, in the meantime, is busy with the recent launch of the GLA45 AMG, the coming C63 AMG and its rumored 4.0-liter V8, the Mercedes-AMG GT and its assault on the Porsche 911 among who-knows-what other skunkworks projects. Moers said the technical partnership is about profit for AMG, clear and simple, and, "All these rumors about platform sharing are nice but no one at Aston or Mercedes has the time to discuss them."

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.
