Its powerful engines are the main reason the Audi Q2* is so much fun to drive. Three TDI and three TFSI engines with outputs ranging from85 kW (116 hp) to 140 kW (190 hp) are available. In keeping with the Audi philosophy of rightsizing, there is the proper displacement for each requirement. The base gasoline engine is a small-displacement three-cylinder unit, whereas the top engines are four-cylinder units displacing two liters. Direct injection and turbocharging are standard.
Highly refined with three cylinders: the 1.0 TFSI (116 hp)
The smallest gasoline engine in the Q2 lineup is all grown up with respect to refinement and power development. From 999 cc, it produces 85 kW (116 hp) and 200 Nm (147.5 lb-ft) of torque between 2,000 and 3,500 rpm. Thanks to its compact design and aluminum crankcase, the three-cylinder engine weighs just 88 kilograms (194.0 lb). Its aluminum pistons and forged connecting rods are so finely balanced that it is smooth and refined even without a balancer shaft. Throughout the crank drive the masses are low in magnitude, as is the friction loss. The crankcase and the cylinder head have their own cooling circuits; the exhaust manifold integrated into the head is an important component of the effective thermal management. To improve load changes, the intake and exhaust camshafts can be moved through 50 and 40 degrees of crankshaft rotation, respectively. The common rail system injects at to 250 bar – a top figure for TFSI engines. The turbocharger’s intercooler is an integral component of the intake manifold. Boost pressure, which can reach up to 1.6 bar relative, develops spontaneously.
High-tech with four cylinders: the 1.4 TFSI COD (150 hp)
The 1.4 TFSI COD has a displacement of 1,395 cc and produces 110 kW (150 hp); its 250 Nm (184.4 lb-ft) of torque is available between 1,500 and 3,500 rpm. It comes with a technology package similar to that of the 1.0 TFSI, supplemented with COD (cylinder on demand) cylinder deactivation.
Combined with the manual six-speed transmission, the COD system deactivates the second and third cylinders at loads up to 100 Nm (73.8 lb-ft) and while coasting when engine speed is between 2,000 and 3,200 rpm. If the dual-clutch transmission is installed, cylinder deactivation occurs sooner, between 1,400 and 3,200 rpm. This is done by means of pins that are extended within milliseconds electromagnetically to activate the so-called cam pieces – sleeves that each have two different cam profiles – on the camshafts.
When the zero-stroke profiles are rotating above the valves, they do not actuate the valves, and the valve springs keep them closed. Injection and ignition are deactivated. The operating points in active cylinders one and four are displaced toward higher loads, increasing efficiency. Even during two-cylinder operation, vibration of the 1.4 TFSI COD is still very low and
the engine is quiet.
When the driver pushes the pedal for fast acceleration, the shut-down cylinders are reactivated. In the NEDC cycle, the COD system reduces fuel consumption by roughly 0.4 liters per 100 kilometers. With a moderate driving style, this can be as high as 20 percent. The Audi Q2 1.4 TFSI COD S tronic consumes only 5.2 liters of fuel per 100 kilometers (45.2 US mpg) with CO2 emissions of 119 grams per kilometer (191.5 g/mi). With a manual gearbox, it consumes on average just 5.4 liters (43.6 US mpg), corresponding to 124 grams CO2 per kilometer (199.6 g/mi).
The sprint from 0 to 100 km/h (62.1 mph) takes 8.5 seconds. The Q2 1.4 TFSI reaches a top speed of 212 km/h (131.7 mph).
Revolutionary combustion process: the 2.0 TFSI (190 hp)
The top gasoline engine is the 2.0 TFSI. Displacing 1,984 cc, it produces 140 kW (190 hp) and delivers 320 Nm (236.0 lb-ft) of torque to the crankshaft between 1,500 and 4,180 rpm. Its new combustion process and an extensive package of high-tech solutions provide for sporty performance and exemplary efficiency across the entire engine-speed range. In part-load operation, the four-cylinder engine realizes the fuel economy benefits of a downsizing engine, while offering the benefits of an engine with large displacement at higher loads. The Q2 2.0 TFSI is combined with S tronic and quattro all-wheel drive as standard.
Powerful entry-level diesel: the 1.6 TDI (116 hp)
The 1.6 TDI with a displacement of 1,598 cc produces 85 kW (116 hp) and delivers 250 Nm (155.3 lb-ft) of torque between 1,500 and 3,200 rpm. The compact four-cylinder engine accelerates the Audi Q2 in 10.3 seconds from 0 to 100 km/h (62.1 mph) and beyond to a top speed of 197 km/h (122.4 mph). Yet in the NEDC it consumes just 4.4 liters of fuel per 100 kilometers (53.5 US mpg), corresponding to 114 grams CO2 per kilometer (183.5 g/mi).
The 1.6 TDI impresses with minimal internal friction. This applies, for example, to the piston rings, the cylinder barrels, the toothed belt and the carbon-coated bolts of the cast-aluminum pistons. A two-stage oil pump, a turbocharger with variable turbine geometry and an intake manifold with integrated intercooler round out the technology package.
Clear best-seller: the 2.0 TDI (150 hp/190 hp)
The 1,968 cc, four-cylinder TDI is particularly popular in the Audi lineup. It is available in the Q2 at two output levels. In the first version, it produces 110 kW (150 hp) and 340 Nm (250.8 lb-ft) of torque between 1,750 and 3,000 rpm. These figures in the top version are 140 kW (190 hp) and 400 Nm (295.0 lb-ft) between 1,900 and 3,300 rpm. The 110 kW variant comes with a manual six-speed transmission; S tronic is optionally available. The top diesel model is fitted with a dual-clutch transmission and quattro all-wheel drive as standard.
The 2.0 TDI is packed with high-tech solutions: two balancer shafts in the crankcase, minimized internal friction, separate cooling circuits, a cylinder pressure sensor and a common rail system with a maximum pressure of 2,000 bar.
