The design of the Spyder is strongly based on the e-tron Detroit Concept, especially in the front and in the side view.
Compared to the e-tron Detroit, the Spyder has slightly larger dimensions, with a length of 4.06 m, a width of 1.81 m, a height of 1.11 m and a wheelbase of 2.43 m.
They form a single unit with the windshield, which is strongly bowed and "inclined like the visor of a helmet."
The the rear end features a dark-grey fascia that integrated the LED tail lights and the rear grilles. Both these elements show a clear inspiration from the R8 supercar.
The e-tron Spyder has a hybrid plug-in powertrain with a rear-mounted 6 cylinder TDI engine capable of 300 hp – derived from the biturbo unit of the A8.
The engine is combined with two front-mounted asyncronous electric motors with an output of 88 hp. The transmission features a 7-speed DSG gerbox and an all-wheel-drive system.
The main performance are a 0-100 km/h acceleration in 4.4 seconds, a top speed limited to 250 km/h and an average fuel consumption of about 2.2 liter/100 km.
