Audi A6 (C7) 3.0 BiTdi review vs Mercedes E63 AMG comparison

Review of my Audi A6 Avant (C7) 3.0 BiTdi, which has some minor modifications and is running over 400bhp and 820nM, including stage 1 remap. I also compare it (probably unfairly!) to my Mercedes E63 AMG (S212 with the 5.5 BiTurbo V8 M157) to see if it could be a possible replacement for that car.

My brother owns a normal 2 litre diesel saloon but I've driven a bi turbo estate. Didn't know it was bi turbo until I put my foot down and felt the second kick in. Plenty of power

Yes, they move pretty well for a diesel! It's the torque that really impressed me, it makes for effortless acceleration.
