Audi introduces new 1.6 TDI engine on the A3 range

Article by Christian A., on August 25, 2010

It was recently made public by the German carmaker Audi that they have come up with a new pair of common-rail diesel powerplants that will augment its A3 and A3 Sportback series. The top power-yielding 1.6-liter TDi can provide a maximum of 105hp and a top torque of 230Nm (170lb-ft), and is joined with the latest start/stop and energy recovery technologies of Audi.

Equipped with this power unit, the A3 can accelerate from 0-100km/h in 11.4 seconds and attain a ceiling speed of 194km/h with an average diesel fuel consumption of 4.1 liter per 100km.

CO2 emissions is rated at 109g/km. The 1.6-liter TDi that powers the A3 also comes with a 90hp variant that is able to propel the car from standstill to 100km/h in 12.9 seconds to reach a maximum speed of 180km/h.

Since this model is not equipped with a start/stop or energy recovery system, the fuel consumption is higher at 4.5 liters/100km and carbon dioxide emissions is rated at 118g/km.

Available in Europe, the A3 1.6 TDi comes with a 22,550 Euro price tag for the 90hp version, while the 105hp version costs 23,550 Euros. An additional 900 Euros will be charged for those who would choose the 5-door Sportback model.

For the German premium carmaker, the term means being able to offer vehicles with a turbocharged engine with smaller capacity but boasts of outstanding efficiency and handling. To achieve this, Audi combined a number of elements from its modular efficiency platform.

For instance, the carmaker installed the A3 with a start/stop system as standard. This feature allows the vehicle to become more fuel efficient especially during city driving. When the vehicle stops during heavy traffic or on a stop signal and the shift lever is in neutral, the system turns the engine off as soon as the driver lets go of the clutch pedal.

As soon as the driver steps on the clutch pedal, the engine then turns back. Interestingly, the A3 could return savings on fuel even before it comes into a halt, thanks to Audi's energy-recovery system.

This system features an alternator that could convert kinetic energy generated by coasting or braking to usable energy and temporarily stores it in the battery.

When the driver drives off or accelerates the A3, the battery will send the stored energy to electrical components, thereby reducing the load on the alternator and saving up to three percent fuel.

2009 Audi A3 1.6 TDI Introduced

With its new 1.6 TDI engines, Audi demonstrates once again that driving pleasure and efficiency are not mutually exclusive. With consumption of just 4.1 liters of diesel per 100 kilometers (57.37 US mpg), the A3 1.6 TDI with an output of 77 kW (105 hp) emits a mere 109 grams of CO2 per kilometer (175 g/mile). 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 77 kW (105 hp) allows the Audi A3 to reach 100 km/h (62 mph) in 11.4 seconds and powers it quickly up to a top speed of 194 km/h (121 mph). The smaller 1.6 TDI delivers 66 kW (90 hp) and transmits 230 Nm (170 lb-ft) of torque. The A3 1.6 TDI can be ordered at once; the basic price is 22,550 Euros for the engine with 66 kW (90 hp) and 23,550 Euros for 77 kW (105 hp).

The new 1.6 TDI engine, delivering 77 kW (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. Audi achieves this 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 (57.37 US mpg). This equates to just 109 grams of CO2 emissions per kilometer (175 g/mile).

The 1.6 TDI with an output of 66 kW (90 hp) also offers good performance and fuel efficiency. With its high torque of 230 Nm (170 lb-ft), this engine version propels the Audi A3 to 100 km/h (62 mph) in 12.9 seconds and a top speed of 180 km/h (112 mph). Even without a start/stop system or energy recovery, it sips a mere 4.5 l/100 km of diesel (52.27 US mpg) – thereby emitting just 118 grams of CO2 per kilometer (190 g/mile).

Both versions of this new four-cylinder turbocharged diesel with common-rail technology further cement Audi’s reputation as a pioneer. Despite lower displacement, fuel consumption is lower while handling remains as outstanding as ever.

The Audi A3 1.6 TDI is also available as the A3 Sportback. The extra charge for the Sportback versions is 900 Euros. The basic price is 22,550 Euros for the version with 66 kW (90 hp); the model with an output of 77 kW (105 hp) starts at 23,550 Euros.
