Audi A1 Sportback Concept

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 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. Multi-hole injectors result in very homogeneous mixture formation and extremely efficient combustion. This is also an effective means of helping to cut pollutant emissions.

The integrated turbocharger promises optimized responsiveness and even more harmonious torque build-up. 80 percent of peak torque can be summoned up from as low down as 1,250 rpm, in other words barely above idling speed. And despite its power, the 1.4 TFSI sets new benchmark standards in its class for its acoustic output too.

The Audi A1 Sportback concept can in principle run self-sufficiently, using mixed operation of the combustion engine and electric motor. Thanks to the intelligent management of both units, energy regeneration as well as the automatic start/stop function, fuel consumption is almost 30 percent lower compared to a vehicle running on the gasoline engine alone. Although the components of the electric motor add around 40 kilograms to the overall weight, the study still only burns 3.9 liters of premium fuel per 100 km (60.31 US mpg) in mixed mode, while CO2 emissions average just 92 g/km (148.06 g/mile).

The styling of the five-door 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 A1 is likely to be seen first at the Geneva Show in March and then launched in the UK in October.
