At the Paris Motor Show (October 2-10, 2008), Audi unveiled the A1 Sportback concept study: following on from the Audi A1 project quattro, the three-door show car presented in 2007, this is a concept for a five-door four-seater for the sub-compact class – once again exhibiting all the characteristics of a genuine Audi. The 3.99-meter long (13.09 ft) and 1.75-meter wide (5.74 ft) vehicle combines cutting-edge, dynamic styling with optimum economy of space and supreme quality. At the same time, a series of visionary technical solutions take efficiency, dynamism and motoring pleasure into new territory as only Audi knows how.
Audi is presenting another version of the innovative hybrid technology in the drive unit for the A1 Sportback concept. At work under the hood is a 1.4-litre TFSI engine developing 110 kW (150 hp), whose power is directed to the front wheels by means of the S tronic dual-clutch transmission. A 20 kW (27 hp) electric motor integrated in the drive train is able to deliver up to an additional 150 Nm of torque (110.63 lb-ft) when the vehicle is accelerating. During the boosting phase, i.e. when the TFSI engine and electric motor operate simultaneously to enable a sporty driving style, the two power packs deliver impressive propulsion. The tried-and-tested front-wheel drive – supplemented by the newly developed, ESP-controlled active front differential lock – ensures optimum transfer of power to the road.
The electric motor is furthermore capable of powering the vehicle alone for zeroemission driving in residential areas, for instance. The capacity of the lithium-ion batteries gives the vehicle a range of up to 100 km (62.14 miles) in pure electric mode; the motor can be recharged from any power socket. The automatic start/stop facility, energy regeneration and phases of purely electrical operation reduce the fuel consumption and emissions of the Audi A1 Sportback concept by almost 30 percent compared to when it is running on the combustion engine alone. Despite its sporty performance, with acceleration of 0 to 100 km/h (62.14 mph) in 7.9 seconds and a top speed of 200 km/h (124.27 mph), the Audi A1 Sportback concept requires only 3.9 liters of premium fuel per 100 km (60.31 US mpg); CO2 emissions are an efficient 92 g/km (148.06 g/mile).
The difference is not down to the two extra doors alone: the styling of the fivedoor concept vehicle is a consistent development of the three-door study, the Audi A1 project quattro from the year 2007. Surfaces and lines are distinctly tauter and more masculine. The basic proportions, with a high vehicle body and a flat window area bordered by a coupe-like roof line, produce a virtually classic look for a vehicle bearing the four rings. The rear end is rounded off by a two-part spoiler with a striking centre groove, integrated into the rear window.
The interior, with its four individual seats and a surprisingly generous amount of spaciousness for this class, has a tidy, no-frills appearance. The curved, wraparound section combines the doors and the sporty cockpit into one single unit. The dashboard and center console are designed entirely around the driver. Ergonomics and aesthetics unite to create an ambience of clear-cut architecture and high-class appeal. Details such as the turbine-look air vents and air conditioning controls seem to be straight out of a jet plane. This is where advanced form and precise function are combined in typical Audi fashion: air flow direction and volume can be regulated simply and intuitively by turning or pressing the control button in the centre of the vent. The center console accommodates the integrated selector lever, only extended in drive select dynamic mode, the start/stop button for the engine, the switch for Audi drive select and the armrest with an integrated mobile phone pocket.
Characteristic Audi sportiness plus a whole new dimension in efficiency – it is all down to the combination of a state-of-the-art turbocharged FSI engine with an electric motor and innovative control electronics. Under the hood of the Audi A1 Sportback concept sits a four-cylinder TFSI with a capacity of 1.4 liters and a turbocharger. This engine is an advanced version of the unit that made its series production debut in the Audi A3. Whereas the 1.4 TFSI musters 92 kW (125 hp) in the A3, it delivers 110 kW (150 hp) at 5,500 rpm in the study. Its peak torque of 240 Nm (177.01 lb-ft) is on tap over a broad rev band from 1,600 – 4,000 rpm.
Power transmission to the front wheels is the task of the sporty Audi S tronic dual-clutch gearbox. It allows the driver to change gear in fractions of a second without the use of a clutch pedal and with no interruption to the power flow. If required, the transmission performs the gear changes fully automatically, too. If the driver wishes to change gear manually, he can do so by using the shift paddles mounted on the steering wheel. Reverse gear and neutral are engaged via the gear knob on the centre console. The park position is automatically selected when the electric parking brake is engaged.
Between combustion engine and transmission sits the 20 kW (27 hp) electric unit, which cuts in automatically depending on the selected operating mode – or propels the vehicle alone. The battery unit – a package of compact lithium-ion batteries – is installed at the rear of the vehicle, which makes for a good weight balance. When powered solely by the combustion engine or purely by the electric motor, and when both are used in the boost mode, the A1 Sportback concept operates as a front-wheel drive vehicle. The high torque of 390 Nm in total (287.64 lb-ft) – 240 Nm (177.01 lb-ft) from the 1.4 TFSI plus an extra 150 Nm (110.63 lb-ft) from the electric motor – is transformed into the required level of tractive power when accelerating.
