With its permanent all-wheel drive, the A4 allroad quattro is equally at home on road and off. It is somewhat larger, particularly in height, than the A4 Avant on which it is based. It offers 180 millimeters (7.09 in) of ground clearance, and distinctive design details underscore its powerful character. Here, too, the trunk holds from 490 to 1,430 liters (17.30 to 50.50 cu ft) of luggage. Optional features include a load-securing set and an electromechanical rear hatch. The Audi A4 allroad quattro is available with a choice of one gasoline and three diesel engines. The 2.0 TDI with 105 kW (143 hp) combines the recuperation system with the start-stop system. Like the 2.0 TDI with 125 kW (170 hp), it is available only with a six-speed manual transmission. The seven-speed S tronic is available as an option for the 2.0 TFSI and the 3.0 TDI.
