This collaboration may not just stop at motors. Apparently Aston needs a complete technology overhaul so Mercedes will provides other aspects to bring the Aston lineup up to speed technologically to make it more modern.
So what is causing all this speculation? Italy's Investindustrial firm purchased a 37.5% stake in Aston Martin. Investindustrial owned Ducati previously which before being sold to Audi was negotiating with AMG. A Mercedes source now tells Autocar that Investindustrial is asking for Mercedes to be Aston's technology partner.
We will likely see Mercedes AMG V12 motors and likely other AMG engines under the hood of Aston's. This will certainly make Aston vehicles much more potent performance wise. Certainly an interesting development to watch.
