VW unveils its replacement for the 1.4 TSI engine, the 1.5 VGT

The celebrated 1.4 TSI engine from Volkswagen, member of the EA 211 family, will be replaced. But no one will miss it, considering what will come in its place: a 1.5 engine (what happened to downsizing?) with VGT, of variable geometry turbo, a first when it comes to mass-produced engines. The only petrol engines to present VGT until now were from Porsche. The technology is more common in turbodiesel mills. This is why it is fair enough to name the 1.5 EA211 TSI Evo engine, as Volkswagen calls it, simply as 1.5 VGT.


This amazing resource is not the only surprise the new VW engine brings. It will also adopt the Miller cycle, exactly like the 2.0 engine used by the new Audi A4 and the restyled A3, even if Audi prefers to call it “cycle B”. The other features are a special coating (APS, or atmospheric plasma spray) for less friction inside the cylinders, a cylinder deactivation system, for better fuel efficiency, and a high pressure direct injection system, but this last one is not exactly new.


One of the main problems for using VGT in petrol engines were the high temperatures of the exhaust gases, which required very special components, able to resist the heat. This is why only Porsche engines had it: cost. The variable geometry system uses nozzles to control the air flux and control the behavior of the turbocharger. You can have more torque at a lower rpm and more power at high rpm, in short. Check how the system works below.

With these resources, the 1.5 VGT will be offered in new cars late this year, initially delivering 96 kW and 110 kW.

In the 96 kw version, it will have 200 Nm of torque from 1,300 rpm to 4,500 rpm. The top power will also spread from 4,750 up to 5,500 rpm. If it proves to be reliable, it will be an incredible new piece of engineering.
