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.
