The 2.0 TFSI, which draws its power from its 1,984 cc of displacement, is available in three variants for the Audi A4. In the first, which drives the Audi A4 35 TFSI, the four-cylinder produces 110 kW (150 metric hp) of power and 270 Nm (199.1 lb-ft) of torque – the latter in the range from 1,350 to 3,900 rpm. In the Audi A4 40 TFSI, it is 140 kW (190 metric hp) and 320 Nm (236.0 lb-ft) (from 1,450 to 4,200 rpm). In the top-of-the-range version Audi A4 45 TFSI, the values are 180 kW (245 metric hp) and 370 Nm (272.9 lb-ft), which are available between 1,600 and 4,300 rpm.

The Audi A4 Sedan 35 TFSI accelerates from 0 to 100 km/h (62.1 mph) in 8.9 seconds and reaches a top speed of 225 km/h (139.8 mph). The Audi A4 Sedan 40 TFSI boasts acceleration from 0 to 100 km/h (62.1 mph) in 7.3 seconds and a top speed of 241 km/h (149.8 mph). The A4 Sedan 45 TFSI completes the standard sprint in only 5.8 seconds and achieves a top speed of 250 km/h (155.3 mph).
The two-liter gasoline engine exhibits many examples of technical finesse. In the versions with power outputs of 110 kW (150 metric hp) and 140 kW (190 metric hp), these include an additional intake manifold injection, which complements the FSI direct injection in part load operation and reduces particulate emissions. The Audi valvelift system(AVS) adjusts exhaust valve lift over two stages to optimize gas exchange. A compact rotary valve module for thermal management and the exhaust manifold integrated in the cylinder head both make a contribution to efficiency. A gasoline particulate filter ensures a further significant reduction in emissions.
The TFSI variants that produce 110 kW (150 metric hp) and 140 kW (190 metric hp) utilize an additional technology that makes them particularly efficient. The B-cycle combustion process with a shortened compression stroke and a long power stroke has been specially designed for part load operation, by far the most common operating mode. With a moderate style of driving, it allows drivers to experience the efficiency of a small displacement engine; while driving in a sporty style, on the other hand, they benefit from the dynamism and performance of a large engine.
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 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.

The seven-speed S tronic impresses with its high level of efficiency. Its two multiplate clutches are arranged axially one behind the other, which reduces drag torque. A centrifugal force pendulum on the two-mass flywheel enables very low operating speeds. The dual-clutch transmission is designed for efficiency-enhancing operation with the MHEV system – for coasting, freewheeling and extended start-stop function.

In the A4 35 TFSI, A4 40 TFSI, A4 30 TDI and A4 35 TDI, the seven-speed S tronic transmits its power to the front wheels.

The balance of the suspension at the intersection point between sportiness and comfort is a great strength of the Audi A4. All engine variants combine great talents – from dynamic handling to a comfortable ride that already comes close to the level of the next higher vehicle class.
