The new Audi A5 Sportback* appears in two TFSI and three TDI engine versions. They produce between 140 kW (190 hp) and 210 kW (286 hp). Compared with the previous model, Audi has reduced their fuel consumption by as much as 22 percent while increasing power output by up to 17 percent.
All engines comply with the limits of the Euro 6 emission standard. The standard, updated start-stop system includes changes that reduce fuel consumption. It already deactivates the engine when coasting up to traffic signals at less than seven (with S tronic) or three km/h (tiptronic) (4.3 or 1.9 mph, respectively).
2.0 TFSI engines
The new Audi A5 Sportback comes equipped with the 2.0 TFSI engine with a displacement of 1,984 cm3 in two performance versions. Its technical highlights include the exhaust manifold integrated into the cylinder head, the rotating core module for the thermal management system, the Audi valvelift system (AVS) for the exhaust valves, the turbocharger’s electric waste gate and dual injection. In the partial load range, indirect manifold injection supplements FSI direct injection.
The top version of the 2.0 TFSI produces 185 kW (252 hp). 370 Nm (272.9 lb-ft) of torque is available between 1,600 and 4,500 rpm. Performance is sporty: With quattro all-wheel drive, it sprints from 0 to 100 km/h (62.1 mph) in 6.0 seconds on its way to an electronically limited top speed of 250 km/h (155.3 mph). The unit consumes 5.9 liters of fuel per 100 kilometers (39.9 US mpg), which corresponds to 136 grams of CO2 per kilometer (218.9 g/mi).
The second version of the 2.0 TFSI has an output of 140 kW (190 hp). 320 Nm (236.0 lb-ft) of torque is available from 1,450 to 4,200 rpm. The power unit is both agile and thoroughly economical. These characteristics are the result of a new strategy: the continued development by Audi of successful engine downsizing into rightsizing. The trailblazing efficiency of the 2.0 TFSI with 140 kW (190 hp) is the result of an innovative combustion principle. The comparatively high displacement is no handicap here – in fact, it is essential. Customers of the new Audi A5 Sportback enjoy the advantages of a small-displacement engine when driving at moderate speeds, without having to compromise when it comes to sporty driving. Because this unit still awaits homologation, no consumption data is available for it yet.
The 1,968 cm3 four-cylinder TDI in the new Audi A5 Sportback develops 140 kW (190 hp). Peak torque of 400 Nm (295.0 lb-ft) is available between 1,750 and 3,000 rpm. With quattro all-wheel drive and the seven-speed S tronic, from 0 to 100 km/h (62.1 mph) takes 7.4 seconds. Top speed is 235 km/h (146.0 mph). In combination with the seven-speed S tronic and front-wheel drive, the 2.0 TDI consumes just 4.2 liters of fuel per 100 kilometers (56.0 US mpg) according to the NEDC standard, a CO2 equivalent of 109 grams per kilometer (175.4 g/mi). High and low-pressure exhaust gas recirculation and sophisticated exhaust gas treatment including an SCR system (SCR: selective catalytic reduction) provide for low emissions.
Audi also offers the 2.0 TDI in an ultra version – its presence is indicated by a badge on the rear end. ultra stands for the most efficient versions of a model line. Modifications to the transmission ratio, optimized streamlining of the body and suspension as well as the use of low-rolling-resistance tires help to further reduce consumption.
The new Audi A5 Sportback 2.0 TDI ultra with front-wheel drive and manual transmission consumes just 4.1 liters of fuel per 100 kilometers (57.4 US mpg) (108 grams of CO2 per kilometer (173.8 g/mi)) in the NEDC cycle, which sets the benchmark in the competitive field.
The two six-cylinder TDI power units offer a blend of power, refinement and impressive efficiency. The 3.0 TDI calls upon a displacement of 2,967 cm3 and is available in two performance versions.
The first variant of the 3.0 TDI produces 160 kW (218 hp). Its torque of 400 Nm (295.0 lb-ft) is available between 1,250 and 3,750 rpm. In the NEDC cycle, the new Audi A5 Sportback consumes just 4.6 liters of fuel (51.1 US mpg), corresponding to CO2 emissions of 119 grams per kilometer (191.5 g/mi).
The new top TDI increases power output by an additional 30 kW (41 hp) for a total of 210 kW (286 hp) and offers 620 Nm (457.3 lb-ft) of torque between 1,500 and 3,000 rpm. This power unit will follow only after market launch and is still awaiting homologation. For this reason, no consumption data is available for it yet.
Audi’s development engineers have extensively updated numerous aspects of the new 3.0 TDI with 210 kW (286 hp). They have optimized combustion chamber filling, the charge cycles and thermal management. The result is increased performance coupled with a further reduction in fuel consumption. Close-coupled catalytic converters treat the exhaust gas effectively.
The top diesel version contains a newly developed turbocharger that is 20 percent lighter, with variable turbine geometry (VTG) and a maximum boost pressure of 3.3 bar. The developers put a lot of work into optimizing the gas flow, with the result that the engine responds highly spontaneously to the accelerator.
