The car itself is stylistically very similar to Audi's R8 production sports car, but there are some key changes. Beyond the more futuristic-looking headlights, taillights, and wheels (not to mention a simplified, tech-laden version of the R8's interior), the e-tron is somewhat smaller than its R8 cousin at 167.7 in. long, 74.8 in. wide, and 48.43 in. tall. The e-tron's wheelbase at 102.4-in. is also shorter than the R8.

Given its aerodynamic profile, 3527-lb weight, and prodigious torque, you might expect acceleration comparable to a top-fuel dragster, but 0 to 62 mph sprints are actually more in line with a production V-8-powered R8, at 4.8 sec. Top speed is electronically limited at 125.
