High-torque and efficientThe TFSI® engines of the Audi A1

The Audi A1 features TFSI® technology. What makes it so special is that it combines the advantages of FSI® – efficiency and dynamics – with turbocharging to improve engine performance.

The newly-developed 1.2 TFSITFSIAudi was the first manufacturer in the world to combine petrol direct injection with turbocharging in large-scale car productionTFSI engine, with an output of 63 kW (86 bhp), features a die-cast aluminium engine block with innovative grey cast iron sleeves and maintenance-free inverted tooth chain. The light-weight piston unit is a low-friction component, and the oil and cooling water circuit with dual-circuit cooling circulation ensure excellent system efficiency. The benefits are reflected in the low average consumption of only 5.1 l/100 km and a maximum torque of 160 Nm at 1,500 rpm.

The sporty 1.4 TFSI engine produces 90 kW (122 bhp) and has been designed with a high top speed and good fuel consumption values in mind. It powers the Audi A1 up to 203 km/h, with a torque of 200 Nm at 1,500 rpm. Its water-cooled intercooler is integrated into the intake manifold; this reduces the volume of the charge-air system and makes it more dynamic. Audi is one of the first manufacturers to combine the S tronicS tronicFaster gearshifts, sportier driving: the S tronic combines the sporty characteristics of a manual gearbox with the advantages of an automatic.S tronic with the start-stop system. Both systems are synchronised with each other; the A1 thus uses less fuel.

The top-of-the-range model, the 136 kW (185 bhp) A1 1.4 TFSI, sprints from a standstill to 100 km/h in 6.9 seconds and keeps accelerating up to 227 km/h. The spontaneous responsiveness and excellent pulling power of the 136 kW (185 bhp) A1 1.4 TFSI can be attributed to 250 Nm of torque and the combination of supercharger and turbocharger. The top A1 model combines efficiency and dynamics – the 1.4 TFSI engine consumes an average of only 5.9 litres of fuel per 100 km and emits just 139 grams of CO2 per km.
