Volkswagen reveals more efficient new 1.5 TSI engine

Volkswagen AG has unveiled the first of its more efficient new-generation EA211 turbo-petrol engines, a 1.5-litre TSI that will replace the 1.4 TSI used in models such as the Golf, Skoda Octavia and Audi A3.


Revealed overnight at the annual Vienna Motor Symposium, this new unit trickle into a range of VW products from the end of 2016. Notably, it has variable turbine geometry — something VW says is the first such application on a “volume-produced” spark ignition engine.

The 1.5 will be available in two applications, producing 96kW (up from 92kW) and 110kW (the same as at present). The 96kW unit has the same 200Nm torque output as before, but you’ll be able to access the maximum from 1300rpm — 100rpm earlier than in the current unit.

Fuel consumption has also been reduced, by up to 1.0L/100km at the top end. Even the base 96kW engine will offer 10 per cent greater efficiency than the current 92kW unit.

Key aspects of what makes the 1.5 different are: it runs on a Miller combustion cycle with a high 12.5:1 compression ratio, has common-rail injection with up to 350 bar pressure, a new thermal management system, cylinder deactivation under low loads and cylinder walls coated in atmospheric plasma spray.

Expect to see the new 1.5 feature in the facelifted Golf, next-generation Polo and a range of other Group models from late 2016.
