TDI engines combine efficiency with a tensile break, with four-cylinder versions of this significant change. A new centrifugal pendulum-type absorber (in the 2.0 TDI 100 kW, 120 kW or 130 kW with Quattro all-wheel drive) in the dual-mass flywheel makes the engine even more refined and quieter at low speeds, as before rising and savings up to 0.2 liters per 100 kilometers.

The average consumption of the Audi A4 sedan is limited to 5.6 liters per 100 km (42.0 MPG US), or 134 grams of CO2 per km (215.65 g / mile). This is a decrease in consumption by 19 percent over the previous engine.

The new 1.8 TFSI engine features a series of innovations in control valves and lift, a new thermal management system, fuel injection system, turbocharger and the integration of the exhaust manifold into the head. The engine weighs 3.5 kg (7.72 lb) and less internal friction is drastically reduced.

Powertrain
The 2011 Audi A4 is available with the buyer's choice of three transmissions.

Also available on S4 quattro with sport differential is back, which gives the S4 a new level of management capacity, actively involved in controlling the distribution of torque between the rear wheels, effectively saturating the outer wheel when cornering . This "strength" of the front of the vehicle at the corner, eliminating understeer more accessible and create excitement for the driver.
