The 4.7-liter V8 in an Aston Martin V8 Vantage

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."
