Using Tesla guts seems to be the preferred method for conversion these days.
Audi hasn't yet released an all-electric car (we're not counting the limited R8 e-tron here), but that doesn't mean there aren't some techies out there who haven't converted Audis to electric on their own...
Here is the project of converting an Audi S5 to electric using a Tesla Model S as a donor.
All 16 battery modules were put inside. The electric motor and inverter were split and installed in the front.
Interestingly, Rich Rebuilds visited the build and despite tons of his own projects, seems impressed by this particular one.
The second video is from one of the dyno runs.
