Further efficient engines added to the Audi A3 range

With consumption of just 4.1 liters of diesel per 100 kilometers , the A3 1.6 TDI with an output of 105 hp emits a mere 109 grams of CO2 per km.

These excellent figures are made possible by efficient technologies such as the start/stop system and energy recovery. Performance is also impressive. The version with an output of 105 hp allows the Audi A3 to reach 100 km/h in 11.4 seconds and powers it quickly up to a top speed of 194 km/h. The smaller 1.6 TDI delivers 90 hp and transmits 230 Nm of torque.

The new 1.6 TDI engine, delivering 105 hp in the Audi A3, reinforces the enhanced efficiency and customer benefits of downsizing: vastly superior fuel efficiency and performance comparable to engines with higher displacement.

For Audi, downsizing means offering customers vehicles with a turbocharged engine and smaller capacity as well as excellent efficiency and handling.

This is achieved by blending several components of the modular efficiency platform. The standard start/stop system is especially effective during city driving. As soon as the vehicle comes to a stop, the shift lever is in neutral, and the driver removes their foot from the clutch pedal, the system turns the engine off. The engine then turns back on as soon as the clutch pedal is depressed.

Yet fuel savings begin before the A3 even halts at traffic lights. Aided by the energy-recovery system, the alternator works hard to convert kinetic energy to usable energy during a vehicle's coasting and braking phases before temporarily storing it in the battery.

Upon driving off or accelerating the vehicle, the battery supplies this stored energy to electrical components - thus reducing the load on the alternator. This saves as much as three percent fuel.

In conjunction with the TDI's common-rail high-pressure injection technology, these systems work together to facilitate fuel consumption of just 4.1 liters per 100 kilometers. This equates to just 109 grams of CO2 emissions per km.

The 1.6 TDI with an output of 90 hp also offers good performance and fuel efficiency. With its high torque of 230 Nm, this engine version propels the Audi A3 to 100 km/h in 12.9 seconds and a top speed of 180 km/h.

Even without a start/stop system or energy recovery, it sips a mere 4.5 l/100 km of diesel - thereby emitting just 118 grams of CO2 per km.
