Audi A3 gets start-stop function with automatic transmission
Audi will combine start-stop function with automatic gearbox to achieve better fuel consumption for their product range. First the combination will be build in Audi A3 1.6 TDI and 1.4 TFSI.
Audi A3 1.6 TDI is a four-cylinder diesel engine delivering 105hp and 250Nm of torque. The power is transmitted to the road by dual-clutch S tronic gearbox. With this engine the hatchback is capable of doing 194km/h and goes from 0 to 100km/h in 11.7 seconds. The overall fuel consumption is 4.2 litres diesel for a 100 km.
The other A3, which will use start-stop function and automatic gearbox is powered by 1.4TFSI petrol engine. This small turbo power unit delivers 125hp and 200N/m of torque. The classic discipline 0-100km/h is achieved in 9.3 seconds and the top speed is 203km/h. The fuel consumption is as low as 5.3l/100km.
Prices for the 1.4 TFSI starts from €23,700 (3-door) and €24,600 (Sportback). The new 1.6 TDI with S tronic will cost €25,500 (base price) for the 3-door and €26,400 for the Sportback.

World premiere: Audi combines start-stop function with automatic transmission
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.
In addition to impressive driving performance, these A3 models sip an exemplary 4.2 liters of diesel per 100 kilometers (56.00 US mpg) (1.6 TDI) or just 5.3 liters (44.38 US mpg) of premium unleaded (1.4 TFSI). This means that the A3 1.6 TDI emits just 109 grams of CO2 per kilometer (175.42 g/mile). With regard to the A3 1.4 TFSI, emissions amount to 124 g/km (199.56 g/mile).
The A3 1.6 TDI is powered by a four-cylinder TDI, which delivers 77 kW (105 hp) at 4,400 rpm from a displacement of 1,598 cc and – between 1,500 and 2,500 rpm – steadily transmits 250 Nm (184.39 lb-ft) of torque to the crankshaft. In conjunction with the S tronic, the TDI propels the three-door A3 from 0 to 100 km/h (0 to 62.14 mph) in 11.7 seconds en route to a top speed of 194 km/h (120.55 mph).
The A3 1.4 TFSI delivers 92 kW (125 hp) from a displacement of 1,390 cc; its maximum torque is 200 Nm (147.51 lb-ft) between 1,500 and 4,000 rpm. In conjunction with S tronic, this vehicle accelerates from 0 to 100 km/h (62.14 mph) in 9.3 seconds and tops out at 203 km/h (126.14 mph).
Also standard in both A3 models is an on-board energy-recovery system. During braking and coasting phases, this intelligently controls the alternator to recover energy, which is temporarily stored in the battery. This energy is then fed back into the electrical system during acceleration – thus reducing the load on the alternator. That saves fuel. The energy-recovery system and the start-stop system unleash their potential in particular in urban-driving conditions – precisely where most customers drive every day.
Audi will begin selling the A3 1.6 TDI and the A3 1.4 TFSI as a three-door and as a Sportback in November 2009. Prices for the 1.4 TFSI remain unchanged at €23,700 (3-door) and €24,600 (Sportback). The new 1.6 TDI with S tronic will sell at a base price of €25,500 for the 3-door and €26,400 for the Sportback.
