Audi has combined for the first time in a model the start-stop system and the S-tronic dual-clutch transmission. This application will be used for the first time in the Audi A3 1.6 TDI with 105 hp and the 1.4 TFSI with 125 hp.
Thanks to this new technology the Audi A3 TDI will have a fuel economy if 56.00 US mpg and the TFSI version of 44.38 US mpg.
The start-stop system turns the engine off as soon as the vehicle comes to a stop; the engine stays off as long as the driver depresses the brake pedal. As soon as the driver removes their foot from the brake pedal, start-stop turns the engine back on – quietly, conveniently and quickly.
Press release after the jump.
