Audi S6 Sportback e-tron vs Tesla Model S (2014-2016)

The Audi S6 Sportback e-tron is the easier car for tight UK car parks: it is 41 mm narrower than the Tesla Model S. In a standard 2,400 mm bay that leaves about 477 mm of total clearance for the Audi S6 Sportback e-tron and about 436 mm of total clearance for the Tesla Model S. The Tesla Model S also turns in a 0.5 m tighter circle, which helps with U-turns and multi-storey ramps.

Over a 8-year ownership window EVcarsguide's degradation model projects roughly 84% battery health for the Audi S6 Sportback e-tron and 85% for the Tesla Model S. That is close enough that capacity loss should not decide between them. Both use NMC-type cells, so for daily use keep the charge limit near 80% to slow degradation.
