•SQ5 with 3.

0 TFSI engine at the Detroit Auto Show
•From zero to 100 km/h (0-62 mph) in 5.3 seconds
•250 km/h (155 mph) top speed

The new Audi SQ5 shown at the Detroit Auto Show is the first ever to be powered by a gasoline engine – in this case one producing 260 kW (354 hp) and 470 Nm (346.65 lb-ft) of torque The new top-of-the-line model, which was designed specifically for markets such as the United States, Canada and China, uses a 3.0 TFSI engine with forced induction. It sprints from zero to 100 km/h (0-62 mph) in 5.3 seconds on its way to a top speed of 250 km/h (155 mph).

The new SQ5 is powered by a free-revving, supercharged, three-liter V6 engine with a displacement of 2,995 cc. Its compressor sits in the 90-degree V of the cylinder banks and is belt-driven by the crankshaft. Two rotors inside the supercharger spin at over 20,000 rpm. The air gap between them is just a few thousandths of a millimeter. The supercharger compresses the intake air to as much as 0.8 bar; two intercoolers then cool it for greater power.

The compressor is located downstream of the throttle valve. Its drive requires little engine power, as the density of the intake air is very low at loads below the supercharging level and when coasting. Torque develops early and quickly due to the short gas paths downstream of the supercharger. Various measures dampen compressor noise. A balance shaft in the engine’s alloy crankcase provides for greater smoothness. Adjustable intake camshafts and flaps in the intake ports provide for good charging efficiency in the combustion chambers.

The 3.0 TFSI engine produces 260 kW (354 hp) between 6,000 and 6,500 rpm, and delivers 470 Nm (346.65 lb-ft) of torque to the crankshaft between 4,000 and 4,500 rpm. The sprint from zero to 100 km/h (0-62 mph) takes just 5.3 seconds – best in its class. Top speed is electronically limited to 250 km/h (155 mph). The Audi SQ5 consumes on average 8.5 liters of fuel per 100 km in the NEDC (21 US mpg). This equates to CO2 emissions of 199 grams per kilometer (320.26 g/m) in the NEDC.

An eight-speed tiptronic and quattro permanent all-wheel drive with torque vectoring transfer the power of the SQ5 firmly to the road. The fast-shifting automatic transmission offers two modes, and the driver can also switch gears manually via the standard shift paddles on the steering wheel.
