AMG-powered Aston Martins still years away

After flirting for several years, Mercedes-Benz and Aston Martin have finally tied the knot. Just don't expect to see any offspring to result from the union for at least three or four years.
This according to Auto Express, which spoke with Daimler chief Dr. Dieter Zetsche at the Frankfurt Motor Show last week. AE reports that a new range of AMG-developed turbocharged V8s, transmissions and electrical components will make their way into the successors to the current V8 Vantage and DB9, but that these models are still a few years off.
Purists might balk at the thought of a Mercedes-powered Aston holding true to the brand's heritage. But while David Brown (for whom the DB range is named) may have steered clear of shoehorning in Detroit muscle into his cars, the entirety of the company's current range is powered by engines borrowing technology from Ford, and that arrangement seems to have worked well for Aston until now. And if you're still skeptical, look no further than Pagani and its AMG-sourced engines and you should have all the proof you need that the new relationship between Daimler and Aston could be a success.

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.

Aston Martin and Lotus each issue recalls

A pair of head-turning high performance cars are catching some attention off a different kind, in the form of safety recalls. Aston Martin and Lotus have issued recalls for the V12 Vantage Coupe and Evora, respectively.
Aston Martin's affects 169 examples of the 2009-2012 V12 Vantage Coupe. It concerns the tire-pressure monitoring system, and is less a malfunction than it is a compliance issue. The TPMS does not alert the driver until the front tire is more than 25 percent below the recommended cold tire pressure. Federal Motor Vehicle Safety Standard No. 138 states that the alarm must sound when tire pressure is "equal to or less than either the pressure 25 percent below" the recommended cold inflation pressure. To address the issue, Aston Martin will notify owners and reprogram the software, free of charge.
As for Lotus, 80 supercharged Evoras have been recalled, all built between February and September, 2011. The problem involves an engine-mounted oil feed pipe, which could rupture, causing loss of engine oil or a possible fire if the oil sprays onto a hot engine.
