Audi 1.8 Litre TFSI Petrol Engine Redesigned To Produce More Power And Torque


It is quite surprising to see that Audi is all over the news for a pretty long while, reason being, firstly the launch of 2012 Audi A6, secondly spied shots of soon to be launched Audi Q3 and now the new redesigned Audi 1.8 TFSI MPFI petrol engine.

Audi has unveiled the revamped turbocharged petrol engine which will be powering the, to be launched Audi A5 sedan. This is the iteration of the same engine that is currently being offered with cars like Audi A4, Skoda Laura and the Skoda Superb.


The company has redesigned the engine intentionally so that it could produce more power and torque out of the same size. Another praiseworthy attribute of this redesigned unit is that it now becomes more fuel efficient than the current one.

The power and torque figures do not matter much but the fuel efficiency is a big concern now a days as petrol prices are soaring after every month or two. The new unit incorporates a turbocharger now and has adopted direct injection technology, which together produce a maximum power of 170 BHP and peak torque of 320 Nm.

The current sibling falls short in both power and torque by 10 BHP and a whopping 70 Nm respectively, making the new one way better in terms of responsiveness and drivability. Believing in the claims of the company, the engine can deliver as much as 17.5 kmpl in a litre of petrol which is astonishing.

The goods about the engine don’t end here as the emissions too show an appreciable drop because of the design modifications. The EURO 6 norms are to implemented by 2015 and well ahead of it, this new engine meets the same. The emissions have shown a drop and now reside near 134 grams/Km.

Changes that made it possible for the engine to perform better include:

  • Higher fuel injection pressures from the previous 150 bar to 200 bar now, imparting a better combustion behavior
  • Altered Valve timing

The previous iterations are being offered in some of the cars as I mentioned above, so it would only be a matter of time before the manufacturer introduces the new engine via a Volkswagen product or Audi A5, which has no confirmation about its launch timeline.
