Audi Introduces Start-Stop System To Automatic A3

START-STOP TECHNOLOGY has become almost commonplace in recent years, but, until now, has largely been limited to models fitted with manual transmissions.

Looking to change that, Audi this week announced a new start-stop system paired with the carmaker's seven-speed S tronic dual-clutch transmission.

As with most systems of its type, Audi's start-stop technology works by turning the engine off when the brake pedal is depressed, switching it back on when the driver lifts off the brake pedal.

Audi is making the system is available with the 1.6 TDI and 1.4 TFSI versions of the A3 only.

The stop-start system is joined by a KERS-like brake energy regeneration system which captures energy and uses it to charge the car's battery, reducing the alternator's load on the engine.

Start-Stop equipped models will be available in the US from November. Audi Australia told TMR this week that there is no official word yet on when the start-stop technology will appear in local Audi models.
