Audi Q5 Engines
A choice of engines
Thanks to Vorsprung durch Technik, making the choice between petrol and diesel engines isn't so easy anymore. Engines of both fuel types offer improved power, lower emissions, sporty performance and increased efficiency. Do you prefer the high-torque pulling power of a diesel or the increased response of a petrol engine?
The choice is yours but, as a rule of thumb, the higher your mileage, the more economical a diesel engine will be.
TFSI: Direct petrol injection and turbocharging combined
TFSI technology unlocks superior power, more dynamic performance and better economy from petrol engines.
For example, the 1.4-litre version of the TFSI engine features great economy and, thanks to its turbocharger, manages to deliver an amazing 200Nm of torque and a top speed of 126mph. Quite simply, it feels as though it's a bigger engine than it is.
You'll notice enhanced driving enjoyment with spontaneous and dynamic torque build up. In turn, this encourages you to change up earlier so you don't feel the need to rev the engine so much, promoting greater efficiency.
This impressive technology hasn't gone unnoticed. The 2.0 litre version of the TFSI engine has been voted "International Engine of the Year" by a panel of 64 motoring journalists from over 30 countries. They cited it as "A blend of performance and efficiency. An example to all engine manufacturers."
TDI: High economy diesel, low emissions, superb power
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
