Volkswagen unveils new generation modular petrol engines

Volkswagen has released details of its next generation TSI turbocharged petrol engine lineup at the International Vienna Motor Symposium. The EA211 TSI evo range is a modular family that is said to offer more power, improved fuel economy and lower emissions than its predecessors. It features Variable Geometry Turbochargers (VGT) and a Miller Cycle combustion process. 

So far, the only engine confirmed from the new range is a 1.5-litre four-cylinder unit, available in 128bhp and 148bhp guises. The 1.5-litre TSI engine replaces the 1.4-litre unit of the current TSI generation and will form the basis of the next generation of plug-in hybrid powertrains for production versions of the T-Cross, the T-Cross Breeze and the T-Roc, as well as the Golf, the Tiguan, the Passat and possibly the Touran. VW says the 1.5-litre TSI engine will make production later this year, although it hasn't yet confirmed which model will receive it first.

This enlarged cylinder size combines with the use of VGT technology to offer a wider window of boost, with the effects being felt from as low as 1,300rpm. Along with improved cooling, an integrated exhaust manifold and freer-moving parts, the new TSI engines also feature cylinder deactivation technology. Reduced inertia and the lastest direct injection technology also gives the new TSI engines faster response rates and cleaner exhaust emissions.
