Audi Q3 Colour

Audi is venturing into a new market segment: The Audi Q3 is a premium SUV in a compact-class form. It is sporty, efficient and versatile - a vehicle that is equally comfortable on or off the road. Every aspect of the Q3 showcases Audi technology - the body, the drivetrain, the chassis and the assistance and multimedia systems. Many of its solutions are straight from the luxury class.
The base version of the Audi Q3, which will be available somewhat later, weighs 1,445 kilograms (3,186 lb). Its rigid, safe and quiet occupant cell integrates a number of ultra-high-strength steels. Both the engine hood and the tailgate are made of aluminum. As is typical of the Q models from Audi, the undivided tail lights are integrated into the tailgate, which wraps around the pillars. At just 0.32, the coefficient of drag is unusually low. The compact SUV is 4.39 meters (14.40 ft) long, 1.83 meters (6.00 ft) wide and 1.59 meters (5.22 ft) high.

Initial lineup: one TDI, two TFSI engines

The Audi Q3 is being launched with a choice of three engines - one TDI and two TFSI units. All three four-cylinder engines combine direct injection with turbocharging, and will feature not only an energy recovery system but also a start-stop system. With power outputs ranging from 125 kW (170 hp) to 155 kW (211 hp), these engines are as efficient as they are powerful. Scheduled to appear somewhat later, the Q3 2.0 TDI with 103 kW (140 hp) and front-wheel drive will average less than 5.2 liters of fuel per 100 kilometers (45.23 US mpg).
The Audi Q3 - which rolls off the assembly line in Martorell, near Barcelona in Spain - went on sale in June 2011. The Q3 2.0 TDI with 103 kW (140 hp) has a base price in Germany of €29,900.

Exterior design

Robust, powerful, sporty - the Audi Q3 has a distinctive road stance. Its progressive design is tightly integrated into the brand's design language. Audi is known for bringing many ideas and innovations from its show cars to production vehicles. The Q3 takes up the concept of the 2007 Cross Coupé quattro showcar.

Its dimensions express the dynamic lines in numbers. The compact SUV is 4,385 millimeters long (14.39 ft) long and 1,831 millimeters (6.01 ft) wide, but only 1,590 millimeters (5.22 ft) high (without antenna and roof rail). The wheelbase measures 2,603 millimeters (8.54 ft); the overhangs are short. The coupe-like roof line and the sharply sloped D-pillars give the Q3 a thoroughly sporty silhouette.

Body

The body of the Q3 establishes the foundation for the high build quality, the sporty handling, the acoustic comfort of the cabin and safety. Large portions of it are made of high-strength steels, which are a decisive factor for the high static and dynamic rigidity. Two torsion rings - in the area of the rear seats and the cutout for the tailgate - also make significant contributions here.

Audi once again demonstrates its competence in "ultra" lightweight construction with the Audi Q3. The front-wheel drive version of the compact SUV, scheduled to appear somewhat later, weighs 1,445 kilograms (3,186 lb), with the body-in-white accounting for just 301 kilograms (664 lb). Even the add-on parts are lightweight. The engine hood and the wrap-around tailgate are made of aluminum. They weigh just 8.8 and 10.8 kilograms (19.40 and 23.81 lb), respectively - nearly 50 percent less than corresponding parts of steel sheet. The engine hood is secured to the body by two releases, allowing a crash-optimized construction with low sheet thicknesses and high geometrical stability.

The occupant cell integrates numerous panels with tailored thicknesses (tailored blanks). 74 percent of all panels in the body are made of high-end steels. Topping the materials pyramid are the hot-shaped steels. The blanks are heated in a furnace to over 900 degrees Celsius (1,652 degrees Fahrenheit) and shaped immediately thereafter at around 200 degrees Celsius (392 degrees Fahrenheit) in a water-cooled pressing die.

Engines

The Audi Q3 is being launched with a choice of three four-cylinder engines - two TFSI units and one TDI. All three displace 2.0 liters and have power outputs between 125 kW (170 hp) and 155 kW (211 hp). A second TDI with 103 kW (140 hp) will follow somewhat later. The engines in the Q3 follow the Audi philosophy of downsizing, substituting forced induction for displacement to achieve strong performance with low fuel consumption.

Highly cultivated: two balance shafts

Among the highlights of the four-cylinder gasoline engine are the intake camshaft, which can be adjusted steplessly across a range of 60 degrees, and the two balance shafts. Equipped with counterweights, they counter-rotate in the crankcase to counteract second-order inertial forces, resulting in a cultivated, low-vibration engine. Weighing just 33 kilograms (72.75 lb), the rigid crankcase of gray cast iron provides good acoustic damping. The cylinder bores have been extensively machined so that the piston rings slide easily with reduced pretension.

A common rail unit injects the fuel into the combustion chambers at a maximum pressure of 150 bar through six-port nozzles. Flaps in the intake manifold swirls the fuel precisely with the intake air. The newly developed turbocharger can withstand exhaust temperatures of up to 980 degrees Celsius (1,796 degrees Fahrenheit), reducing fuel consumption at high load by as much as 0.5 liters per 100 kilometers. The intercooler combines high efficiency with low weight. The regulated oil pump operates at two pressure levels, which also helps to reduce fuel consumption.

The more powerful version of the 2.0 TFSI with 155 kW (211 hp) delivers a brawny and constant 300 Nm (221.27 lb-ft) to the crankshaft between 1,800 and 4,900 rpm. In combination with the standard seven-speed S tronic, the four-cylinder unit accelerates the Audi Q3 from 0 to 100 km/h (62.14 mph) in 6.9 seconds on its way to a top speed of 230 km/h (142.92 mph). Fuel consumption is just 7.7 liters per 100 km (30.55 US mpg) on average, which corresponds to CO2 emissions of 179 grams per km (288.07 g/mile).

The 2.0 TFSI with 125 kW (170 hp) offers 280 Nm (206.52 lb-ft) of torque between 1,700 and 4,200 rpm. Coupled with a six-speed manual transmission, it accelerates the Audi Q3 from 0 to 100 km/h (62.14 mph) in 8.2 seconds. Top speed is 212 km/h (131.73 mph). Its average fuel consumption is 7.3 liters of fuel per 100 km (32.22 US mpg), which corresponds to 174 grams of CO2/km (280.03 g/mile).

Rounding out the Audi Q3 engine lineup somewhat later will be another powerful, turbocharged gasoline engine: the 2.5 TFSI. The sonorous five-cylinder will be the new top-of-the-line engine. With its brawny torque profile and power output of roughly 220 kW (300 hp), it will also top the compact SUV segment.

Groundbreaking efficiency: the TDI engines

The TDI engines from Audi also set new standards, and have done so ever since their introduction 22 years ago. They represent a modern, smart form of sportiness. Their high power outputs, powerful torque, low fuel consumption and cultivation combine to form a harmonious whole.

The long-stroke 2.0 TDI displacing 1,968 cc (bore x stroke 81.0 x 95.5 millimeters [3.19 x 3.76 in]) is a high-tech engine. It tips the scales at just 154 kilograms (339.51 lb). The toothed belt for the two camshafts and the ancillaries is particularly quiet and low-friction. Little energy is needed to drive the water pump and the regulated oil pump, and the crankshaft seals have been optimized for easy running. Two balance shafts rotate in the crankcase.

The common rail injection system generates up to 1,800 bar of system pressure. The fuel is very precisely nebulized into the combustion chambers via eight-port nozzles with up to six injection operations per work cycle. The turbocharger uses adjustable vanes for the spontaneous development of torque, and the induction pipe is made of lightweight polymer. The intake ports, the swirler flaps and the bowls in the pistons generate targeted turbulence in the inflowing air.

The result of all of these measures is excellent thermodynamics in the combustion chambers, allowing the 2.0 TDI to be operated with a high exhaust gas recirculation rate. A compact intercooler greatly reduces the exhaust gas temperature, and the cooler combustion significantly reduces raw emissions of nitrogen oxides.

The two-liter, four-cylinder engine consumes just 5.9 liters of fuel per 100 km (39.87 US mpg) on average, which corresponds to 156 grams of CO2/km (251.06 g/mile). With 130 kW (177 hp) and 380 Nm (280.27 lb-ft) of torque - the latter available between 1,750 and 2,500 rpm - the sprint to 100 km/h (62.14 mph) takes 8.2 seconds, and acceleration only ends when a top speed of 212 km/h (131.73 mph) is reached. The powerful two-liter TDI is mated to the S tronic.

Another version of the 2.0 TDI with 103 kW (140 hp), combined with a manual transmission and front-wheel drive, will follow somewhat later. With 320 Nm (236.02 lb-ft) of torque available between 1,750 and 2,500 rpm, it accelerates the Q3 from 0 to 100 km/h (62.14 mph) in 9.9 seconds on its way to a top speed of 202 km/h (125.52 mph). With an average fuel consumption of less than 5.2 liters per 100 km (45.23 US mpg), the Audi Q3 with 103 kW (140 hp) is the most fuel-efficient premium SUV on the market. With a full 64-liter (16.91 US gallons) fuel tank, it has a range of more than 1,000 kilometers (621 miles).
