Engines
Petrol
FSI direct-injection technology is a unique Audi innovation that
was originally developed for the Le Mans 24-hour endurance
race to deliver more power and torque, as well as enhanced fuel
efficiency. Precisely the right amount of fuel and air are injected
into the combustion chambers, enabling the engine to 'breathe'
more easily. It results in reduced heat loss and increased
output, with around a 15% reduction in fuel consumption and
significantly lower exhaust emissions. We've also developed
TFSI, with either turbocharging or supercharging, which
combines FSI technology with forced induction – giving cars
an extra injection of power.
Diesel
All diesel engines from Audi are known as TDI – Turbo Direct
Injection. This impressive technology was originally pioneered by
Audi in 1989, marking a departure from the noisy, fuel-thirsty
diesel engines of the past. Like its FSI petrol counterpart, the
TDI diesel engine is designed for power and performance, with
low fuel consumption and CO emissions. For instance, the new
2
2.0 TDIe engine emits just 139g/km of CO , making it one
2
of the cleanest engines in its class, and we've also refined our
V6 engines to make them more efficient than ever before.
