A1 Sportback Engines

Engines and CO2

Not surprisingly the Audi A1 range employs the most compact and fuel efficient Audi engines, all of which compensate very effectively for their relatively small displacements with the latest turbo charger technology. The A1 Sportback is available with a choice of TFSI petrol engines and a TDI diesel engine, all optimised by engine Start-Stop and energy recuperation systems to achieve low C02 emissions and fuel consumption.*

A choice of a manual transmission or the seven-speed dual-clutch DSG S tronic gearbox are available.

* Automatic Start-Stop is not available on 1.4 TFSI S tronic (185PS)

TFSI explained

TFSI technology unlocks superior power, more dynamic performance and better economy from petrol engines. In fact, compared with many naturally aspirated engines with more cylinders, TFSI delivers the same sporty performance but using 10 to 15% less fuel.

FSI and turbocharging technology work so well together because the evaporation of fuel in the combustion chamber cools the intake air giving higher compression, improved engine efficiency and, in turn, lower CO2 emissions.

TDI explained

A dedication to pioneering technology has brought Audi peerless expertise in turbocharged diesel engines. All Audi TDI engines are equipped with common rail and piezo injectors to achieve smooth, efficient and quiet combustion. Diesel fuel related emissions are also significantly reduced thanks to a diesel particulate filter, fitted as standard, which filters out almost all soot particles contained in the exhaust gas.

The turbocharger has variable turbine vane geometry to help produce higher torque and greater power for the cubic capacity of the engine. And sophisticated air-flow control also contributes to the engine’s capabilities while simultaneously reducing nitrogen oxide emissions.

Stronic
Smooth gear changes, lower fuel consumption

The revolutionary S tronic transmission combines the responsiveness of a manual gearbox with the convenience of an automatic. Thanks to innovative dual-clutch technology, S tronic can make a gear change in just 0.2 of a second, with no interruption to the power flow, allowing you to benefit as fully as possible from the engine’s output at all times, resulting in better fuel efficiency and lower CO2 emissions.

ESP with electronic cross-axle differential

The Audi A1 Sportback’s sporty driving dynamics are further enhanced by ESP with electronic cross-axle lock. Through targeted breaking, the ESP is able to re-allocate wheel torque, to ensure that torque is distributed according to the driving situation. This is known as torque vectoring.

This technology provides the driver with a more agile vehicle response, improved traction and better driving dynamics than in a vehicle without ESP and electronic axle differential. This results in a sportier drive, and more precise and smoother handling, with a greater level of safety when needed.
