The Audi A1 e-tron Concept shown at the Detroit Motor Show in 2010 is a lightweight, compact two-seater with two electric motors on the rear axle. It is a Mega City Vehicle (MCV) with an innovative drive technology. It comes equipped with a powerful electric motor for zero-emission driving in the city.
The Audi A1 e-tron Concept is very agile thanks to the 75 kW (102 hp) peak power of its electric motor. Continuous output is rated at 45 kW (61 hp), with peak power of 75 kW (102 hp) available in short bursts. 150 Nm (110.63 lb-ft) of torque is continuously available, and peak torque is 240 Nm (177.01 lb-ft).
Besides agile, the power steering of the Audi A1 e-Tron is electro-mechanical and thus particularly energy-efficient. A hydraulic fixed-caliper brake is mounted on the front axle, with two novel electrically-actuated floating-caliper brakes mounted on the rear axle. The large electric motor powering the Audi A1 e-tron Concept can convert braking energy into electric current and feed it back into the electrical system. The 380 volt lithium-ion rechargeable battery has a nominal energy content of 12 kilowatt hours. It comprises 96 prismatic cells and weighs less than 150 kilograms (330.69 lb). The Audi A1 e-tron can drive 50 kilometers (31.07 miles) emission-free in city traffic on the powerful battery. On longer trips, the battery is recharged by a particularly compact internal combustion engine mounted below the luggage compartment.
In addition, The Audi A1 e-tron Concept car has a Wankel engine as a range extender, but other compact concepts are also possible. The small single-rotor Wankel has a chamber volume of 254 cc and runs at a constant 5,000 rpm in its peak efficiency window. Together with the generator, which is powered by the Wankel engine and produces 15 kW of electric power, the complete assembly weighs only around 70 kilograms (154.32 lb).
The innovative Mega City Vehicle, which despite its complex drive technology weighs only 1,190 kilograms (2,623.50 lb) delivers zero-emission driving fun in a modern and sophisticated manner. The vehicle accelerates from 0 to 100 km/h (62.14 mph) in 10.2 seconds and has a top speed of more than 130 km/h (80.78 mph).
Exterior of the Audi A1 e-tron Concept is look very amazing. It’s has “Aqua Mint, pearl effect” paint finish; the contrasting roof arch is offset in “High Gloss Steel dark.” As with the other two e-tron models, the 18-inch wheels with a 20-spoke turbine design convey the high-tech aspiration of the concept. And because an innovative drive concept also calls for innovative information management, the concept car features a freely programmable instrument cluster with a virtual display surface and innovative display and operating concept.
