Just reading a TG mag review of the DB11 with an AMG V8 as an alternative to the usual Aston V12.
Now I don't know much about engines, but I would have thought the transplant team at Malvern towers would be looking hard at a possible tissue match to make this a viable donor.
AMG V8 Twin Turbo 503bhp 28.5mpg 230co2 8 speed
BMW V8 NA 367bhp 23mpg 282co2 6 speed
Still makes all the right noises too, despite the turbos according to the journo.
