The Audi A3 Sportback 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 Sportback e-tron supplies a continuous output of 60 kW (82 hp) and a peak output of 100 kW (136 hp). Maximum torque is a potent 270 Nm (199.14 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 Sportback e-tron can be recharged in about nine hours with a 230-volt household socket; 400-volt three-phase current reduces that to some four hours.
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 Sportback 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.
