Audi A3 e-tron Set for Debut Tomorrow at L.A. Auto Show

Exemplifying the ever-changing intersection of car manufacturers and social media outlets, Audi has previewed its planned A3 e-tron concept via a video posted to Audi USA's Facebook page. Set for debut tomorrow at the L.A. Auto Show, this A3 e-tron is not a version of the platinum-colored A3 e-tron sedan concept shown earlier this year in China. That concept was a second hint at the upcoming MQB-based sedan and this L.A. version is actually a modified version of the A3 e-tron prototype built on the Type 8P A3 Sportback currently on sale in the USA with gasoline and diesel powertrains.
Visual changes to the German A3 e-tron prototype shown above include some mild graphics re-styling and the addition of the A3 S-line's "rotor" alloy wheels in black with red accents like those fitted to the Audi RS 3.
Check out the press release on the L.A. concept below. This release was distributed at the same time as the video and highlights technical details. Below that, watch the video that was posted by Audi to Facebook. Finally, if you'd like to see any more of the German-spec A3 Sportback photo set that we utilized in the production of this story, view them in our photo gallery HERE.

The Audi A3 e-tron is an all-around vehicle for future mobility. A powerful electric motor and a lithium-ion battery impart to this compact car – which weighs less than 1.6 metric tons – agile performance and impressive cruising range. This technical study has already provided a preview of potential series-production solutions.
The permanent magnet synchronous motor in the A3 e-tron supplies a continuous output of 60 kW (82 hp) and a peak output of 85 kW (114 hp). Maximum torque is a potent 270 Nm (199 lb-ft), with the power delivered to the front wheels via a single-speed transmission.
Energy storage is provided by the lithium-ion battery, which is located in multiple blocks under the luggage compartment floor, under the rear seat and in the center tunnel. It stores 26.5 kWh of usable energy at 380 volts and weighs 300 kilograms (661.39 lb). Water flows around the 30 modules which constitute this battery; the waste heat is utilized to heat the vehicle’s interior. At low temperatures, the system is aided by an electric PTC heating element; an air conditioner is activated in hot weather.
The power electronics module in the engine compartment converts the battery’s direct current (DC) to alternating current; a DC converter couples the 12-volt electrical system with the high-voltage system. The Audi A3 e-tron can be recharged in about nine hours with a 230-volt household socket.
On a single battery charge, this compact car can cover around 140 km (86.99 miles). It powers the car from zero to 100 km/h (62.14 mph) in 11.2 seconds and on up to a top speed of 145 km/h (90.10 mph). The driver of an A3 e-tron can decide how sporty or economical driving should be by switching among three modes of operation – dynamic, auto and efficiency – as well as four settings which adjust the degree of energy recovery during braking and coasting phases.
This technology study, with a Glacier White paint finish, sports an understated appearance, with its set of wheels and the interior both borrowed from production models. Its special features include seat covers made of an Alcantara/leather blend – which feels warmer than pure leather in cold weather – and a heated windshield. The latter keeps the glass free of condensation and ice while heating the interior much more efficiently than a conventional climate-control system.
