Based on the regular-production A3 Sportback, the concept ditches the last A3Â e-tron's all-electric drivetrain in favor of a more convenient plug-in hybrid setup. Â It consists of a heavily modified 1.4-liter TFSI four-cylinder engine and a compact 75-kilowatt electric motor that is integrated into a brand new six-speed gearbox called e-S tronic. Â Combined, the two power sources make 204 horsepower and 258 lb-ft. of torque. Â
When driven gently, the e-tron returns 156 mpg in a mixed European cycle and it emits just 35 grams of CO2 per kilometer. Â Alternatively, the hatchback can operate on electricity alone for 31 miles at speeds of up to 80 mph.
If fuel economy is not a concern, the electric motor provides a power boost that enables the A3 e-tron to sprint from zero to 62 mph in 7.6 seconds and reach a top speed of 137 mph.
The A3 e-tron is not likely to be added to the Audi lineup as a regular production model in the near future but the technology found under its skin will be gradually applied to the firm's upcoming vehicles. Â
