The four-cylinder TDI with 1,968 cc of displacement is available in three output variants. The entry-level version achieves between 1,500 and 2,750 rpm with a power output of 100 kW (136 metric hp) and 320 Nm (236.0 lb-ft) of torque. This engine propels the Audi A4 30 TDI (combined fuel consumption in l/100 km: 4.3–3.9* (54.7–60.3 US mpg); combined CO2 emissions in g/km: 113–102* (181.9–164.2 g/mi)). The second version, at home in the A4 35 TDI (combined fuel consumption in l/100 km: 4.2–3.8* (56.0–61.9 US mpg); combined CO2 emissions in g/km: 110–100* (177.0–160.9 g/mi)), has an output of 120 kW (163 metric hp) and produces 380 Nm (280.3 lb-ft) of torque between 1,500 and 2,750 rpm. The most powerful four-cylinder diesel in the A4, which drives the A4 40 TDI (combined fuel consumption in l/100 km: 5.3–4.9* (44.4–48.0 US mpg); combined CO2 emissions in g/km: 140–131* (225.3–210.8 g/mi)), reaches 140 kW (190 metric hp). Between 1,750 and 3,000 rpm, it produces 400 Nm (295.0 lb-ft) of torque.
The 2.0 TDI enables powerful driving performance in all versions. The A4 30 TDI propels the Sedan from 0 to 100 km/h (62.1 mph) in 9.5 seconds and achieves a top speed of 214 km/h (133 mph). With the A4 Sedan 35 TDI, these values are 8.2 seconds and 228 km/h (141.7 mph), and 7.7 seconds and 241 km/h (149.8 mph) with the A4 Sedan 40 TDI. The NEDC values for fuel consumption and CO2 emissions correlated from the WLTP data are 4.3–3.9 liters per 100 kilometers (54.7–60.3 US mpg) (112–102 grams of CO2 per kilometer (180.2–164.2 g/mi)) for the A4 Sedan 30 TDI, 4.1–3.8 liters per 100 kilometers (57.4–61.9 US mpg) (109–100 grams of CO2 per kilometer (175.4–160.9 g/mi)) for the A4 Sedan 35 TDI, and 5.3–4.9 liters per 100 kilometers (44.4–48.0 US mpg) (140–131 grams of CO2 per kilometer (225.3–210.8 g/mi))* for the A4 Sedan 40 TDI.
The 2.0 TDI awaits with complex technical solutions – with separate coolant circuits, two balance shafts in the crankcase, a cylinder pressure sensor and substantially reduced internal friction. The versions with power outputs of 100 kW (136 metric hp) and 120 kW (163 metric hp) are part of a new evolutionary stage. Their crankcase is made from aluminum instead of gray cast iron and weighs 20 kilograms (44.1 lb) less as a result. The thermal management has been revised and the common rail injection system operates with a system pressure of 2,200 bar. The pistons are made from forged steel; the crankshaft is now 2.8 kilograms (6.2 lb) lighter.
The four-cylinder TDI engines are offered exclusively with a dual-clutch transmission that enables comfortable and highly efficient shifting.
* Figures depend on the tires/wheels used
Manual transmission, S tronic and tiptronic, front-wheel and quattro drive – Audi has tailor-made power transmission technology ready for every A4 engine variant. The entry-level gasoline-driven model is equipped with a six-speed manual transmission and will be available shortly after market introduction. Power transmission in all other engine variants is handled by an automatic transmission. Six of them use the seven-speed S tronic; the eight-speed tiptronic is reserved for the A4 45 TDI (combined fuel consumption in l/100 km: 5.6–5.3* (42.0–44.4 US mpg); combined CO2 emissions in g/km: 145–139* (233.4–223.7 g/mi)) with the three-liter diesel engine.
Both automatic transmissions are state-of-the-art. Their lower gears feature short, sporty ratios, while the upper gears are long to reduce revs and fuel consumption. The S tronic and tiptronic transmissions are integrated into the engine’s thermal management. Drivers can choose between the modes D, S and E, or shift gears manually using the selector lever or the shift paddles on the steering wheel. Their commands are transmitted to the transmission electrically – by wire.
