The engine lineup for the Audi Q3 comprises three TFSI units and three TDI clean diesel four-cylinder units. Displacement ranges from 1.4 to 2.0 liters and output from 88 kW (120 hp) to 162 kW (220 hp). All are turbocharged, direct-injection units and comply with the limits of the Euro 6 emission standard. With the help of sophisticated thermal management, they quickly come up to operating temperature following a cold start.

Compared with the previous model, performance is even better and CO2 emissions have been reduced by up to 17 percent (2.0 TDI manual FWD). The 1.4 TFSI COD and the 2.0 TDI clean diesel with 110 kW (150 PS) bear the “ultra” badge as proof of their extraordinary efficiency. Audi models with the name affix “ultra” attain best values in fuel consumption and emissions as the result of a considerable technological input and are the most fuel-efficient automobiles in their segment. The start-stop system is standard with all variants. When braking, it deactivates the engine shortly before the car comes to a stop.

ultra: the 1.4 TFSI COD
The 1.4 TFSI COD is an example of Audi’s rightsizing strategy. Displacing just 1,395 cc (bore x stroke 74.5 x 80.0 millimeters [2.9 x 3.1 in]), it produces a powerful 110 kW (150 hp) and 250 Nm (184.4 lb-ft) of torque, which is available between 1,500 and 3,500 rpm. Equipped with the manual transmission, the Audi Q3 1.4 TFSI ultra accelerates in 9.2 seconds from 0 to 100 km/h (62.1 mph) and reaches a top speed of 204 km/h (126.8 mph).

With 17-inch tires optimized for fuel consumption, its NEDC consumption is just 5.5 liters per 100 Kilometers (42.8 US mpg), corresponding to 127 grams CO2 per kilometer (204.4 g/mi). With the optional six-speed S tronic, these values are 5.8 liters per 100 kilometers and 134 g CO2 per kilometer (40.6 US mpg and 215.7 g/mi). The standard sprint takes 8.9 seconds, and top speed is 204 km/h (126.8 mph).

The 1.4 TFSI COD, which with its aluminum crankcase weighs barely more than 110 kilograms (242.5 lb), features the highly innovative cylinder on demand (COD) system, which when driven moderately reduces fuel consumption by up to 20 percent. At low to moderate load and engine speed, it deactivates cylinders two and three by closing the valves and shutting off fuel injection. The engine runs as a two-cylinder engine until the driver presses down harder on the gas pedal. The operating points in the active cylinders are displaced toward higher loads, increasing efficiency. The extremely well-balanced engine remains very smooth.

Sporty: the 2.0 TFSI
The 2.0 TFSI is available in two variants, with numerous engineering features documenting Audi’s high-end competence. These include the additional indirect injection supplementing the direct injection of the FSI, the Audi valvelift system to adjust the valve stroke on the exhaust side and particularly effective thermal management, which uses a rotary valve module and an exhaust manifold integrated into the cylinder head. Displacement is 1,984 cc (bore x stroke 82.5 x 92.8 millimeters [3.2 x 3.7 in]).

Even in the version with 132 kW (180 hp) and 320 Nm (236.0 lb-ft), the latter between 1,400 and 3,900 rpm, the two-liter is a sporty engine. In combination with the manual transmission and front-wheel drive (quattro all-wheel drive), it accelerates the Audi Q3 in 8.3 (7.6) seconds from a standstill to highway speed (62.1 mph). Top speed is 217 km/h (134.8 mph). The 2.0 TFSI consumes on average just 6.7 (6.9) liters of fuel per 100 kilometers (35.1 [34.1] US mpg) with 152 [160] grams CO2 per kilometer (244.6 [257.5] g/mi) (all values provisional). These same figures for the Q3 2.0 TFSI with seven-speed S tronic and quattro all-wheel drive are 7.6 seconds, 217 km/h (142.84 mph), 6.5 liters per 100 kilometers (36.2 US mpg) and 149 g per kilometer (239.34g/mi).

The top version of the 2.0 TFSI produces 162 kW (220 hp), with 350 Nm (258.1 lb‑ft) of torque available between 1,500 and 4,400 rpm. Power in this case is transferred via a seven-speed S tronic and quattro permanent all-wheel drive. The figures document the superiority of this combination of technologies: 0 to 100 km/h (62.1 mph) in 6.4 seconds; top speed 233 km/h (144.8 mph); NEDC consumption 6.6 liters per 100 kilometers (35.6 US mpg), corresponding to 152 g CO2 per kilometer (244.6 g/mi).

Highly efficient: the 2.0 TDI
The diesel engines are three versions of the 2.0 TDI clean diesel, which Audi offers with various outputs. It displaces 1,968 cc (bore x stroke 81.0 x 95.5 millimeters (3.2 x 3.8 in) and features minimal internal friction. Among the technologies used are two balance shafts in the crankcase, a thermal management system with separate coolant pumps for the cylinder block and head, a common rail injection system with a max. pressure of 2,000 bar and a turbocharger with adjustable vanes. The cylinder head features a rotated valve star. As a result, the intake and exhaust valves appear to be arranged one behind the other when viewed from the induction pipe connection. Each camshaft thus actuates one intake and one exhaust valve per cylinder.

The 2.0 TDI clean diesel shares two other solutions with the 1.4 TFSI – the separate valve drive module and the intercooler integrated into the intake manifold. A complex emission control system enables compliance with the Euro 6 standard. Nitrogen oxides are reduced in the particulate filter, to which the required SCR coating has been applied (SCR = selective catalytic reduction).

The 1.4 TFSI ultra is joined by a particularly efficient ultra variant of the 2.0 TDI engine. Equipped with a manual transmission and front-wheel drive, it produces 110 kW (150 hp) and 340 Nm (250.8 lb-ft). Acceleration from 0 to 100 km/h (62.1 mph) takes 9.6 seconds, and top speed is 204 km/h (126.8 mph). Fuel consumption is 4.4 liters per 100 kilometers (53.5 US mpg), a CO2 equivalent of 114 grams per kilometer (183.5 g/mi).

The 2.0 TDI clean diesel with 110 kW (150 hp) and 340 Nm (250.8 lb-ft)
(between 1,750 and 2,800 rpm) will also be available at launch with a choice of two versions of quattro all-wheel drive: quattro all-wheel drive and manual transmission, and quattro all-wheel drive and seven-speed S tronic. The figures with manual transmission and S tronic, respectively: 9.3/9.3 seconds, 204/204 km/h (126.8 mph), 4.9/5.1 liters per 100 kilometers (48.0/46.1 US mpg) and 129/132 grams CO2 per kilometer (207.6/212.4 g/mi).

The most powerful TDI in the Audi Q3 produces 135 kW (184 hp). Its torque plateau of 380 Nm (280.3 lb-ft) extends from 1,800 to 3,250 rpm. Here, too, Audi offers the three variants front-wheel drive and manual transmission (provisional values), quattro all-wheel drive and manual transmission, and quattro all-wheel drive and seven-speed S tronic. The figures: 0 to 100 km/h (62.1 mph) in 8.3/7.9/7.9 seconds; top speed 219/219/219 km/h (136.1 mph); NEDC consumption 5.0/5.2/5.1 liters per 100 kilometers (47.0/45.2/46.1 US mpg); CO2 emissions 131/137/134 grams per kilometer (210.8/220.5/215.7 g/mi)
