Two new versions of Audi’s best-selling A4 now consume less fuel and are available in Germany. The sedan consumes 4.4 liters of diesel per 100 km (53.5 US mpg) on average, with CO2 emissions of 115 grams per km (185 g/mile). These same figures for the A4 Avant are 4.6 liters (51.1 US mpg) and 120 grams (193 grams). CO2 emissions have been reduced by four and nine grams, respectively, compared with the previous models.

The two-liter TDI engine in the new models generates 100 kW (136 hp) and 320 Nm (236 lb-ft) of torque, the latter of which is available between 1,750 and 2,500 rpm. The sedan accelerates from zero to 100 km/h (62 mph) in 9.5 seconds on its way to a top speed of 215 km/h (134 mph); the Avant completes the standard sprint in 9.8 seconds and reaches 208 km/h (129 mph).
The two new A4 models use the technologies from Audi’s modular efficiency platform. All the gear ratios of their six-speed manual transmissions were lengthened slightly, and the forged 16-inch alloy wheels are shod with 206/60 tires that have been optimized with respect to rolling resistance. Aerodynamic tweaks to the body and a lower ride height improves the drag coefficient, while the on-board computer with efficiency program gives the driver tips about when to shift and on fuel-efficient driving.
Audi offers the two new efficiency top models in the A4 series in the Attraction trim line. The Audi A4 2.0 TDI (100 kW 115 g CO2/km) has a base price of €31,600 (US$45,000); prices for the A4 Avant 2.0 TDI (100 kW 120 g CO2/km) start at €33,250 (US$47,300).
