Audi A3 Sportback
From Audi press: The Audi A3 and A3 Sportback are the sporty models in the compact segment. The upscale equipment and trim underscores their elegant style. Audi optionally equips its two premium compact models with highly developed technologies such as the S tronic dual-clutch transmission, the Audi magnetic ride suspension system and quattro permanent all-wheel drive. All of the engines combine powerful and sporty performance with low fuel consumption. The A3 1.6 TDI sets efficiency standards with CO2 emissions as low as 99 grams per km (159.33 g/mile).
There are eight powerplants in the engine lineup for the Audi A3 and the A3 Sportback – four gasoline and four diesel units. All are cutting-edge four-cylinder units featuring turbocharging and direct injection and badged as TFSI and TDI. They offer all the qualities of Audi engine technology – efficiency, refinement, power and high torque. Audi couples most of the engines with a start-stop system that works together with both the manual and the S tronic automatic transmissions. The recuperation systems is standard with all engines.
The entry-level gasoline engine is the 1.2 TFSI; it exemplifies Audi’s downsizing strategy – the substitution of turbocharging for displacement. The four-cylinder unit develops 77 kW (105 hp) and a hefty 175 Nm of torque (129.07 lb-ft) from its small displacement of 1,197 cc, yet averages just 5.5 liters of fuel per 100 km (42.77 US mpg). The most powerful gasoline engine is the 2.0 TFSI with 147 kW (200 hp).
The TDI range extends from the 1.6 TDI developing 66 kW (90 hp) to the 2.0 TDI, with an output of 125 kW (170 hp). The most efficient engine in the lineup is the 1.6-liter TDI with 77 kW (105 hp). It is available in a variety of different versions, the most economical of which averages 3.8 liters of fuel per 100 km (61.90 US mpg) in a three-door A3 with manual transmission. In-detail modifications to the body and chassis contribute towards this excellent figure.
The range of transmission technologies is equally very diverse. Most engine versions in the A3 model series are paired with a six-speed manual transmission. Audi offers many of the engines with the extremely fast and comfortably shifting S tronic. Shift paddles on the steering wheel are standard in the Ambition line. Depending on engine version, the dual-clutch transmission has six or seven speeds. The seven-speed version uses dry clutches; the elimination of the oil supply further improves the transmission’s already high efficiency.
The transmission of power to all four wheels likewise underscores the exceptional position that the Audi A3 enjoys in the premium compact class. Audi supplies quattro permanent all-wheel drive for four engine versions. Its electronically controlled multi-plate clutch, mounted on the rear axle in the interest of weight distribution, sends most of the engine’s power to the front wheels under normal driving conditions. If need be, it diverts torque extremely quickly and flexibly to the rear wheels.
