The valve train is operated by low-friction hydraulic roller finger followers and driven by a timing chain with a maintenance-free hydraulic tensioner. The design and sizing of the turbocharging system plays a key role in enabling downsized engines to deliver excellent performance and drivability, while meeting CO 2 targets.

3 B-Cycle gasoline engine is the first example of Volkswagen’s “Rightsizing” strategy—an engine development strategy that looks to for the optimal balance of displacement, output, torque and efficiency based on vehicle class and real-world operating conditions, rather than just seeking to downsize. Third, the EA888 2.0TSI Gen.3

At present, PHEV technology alone is equipped to improve the current electric grid. The plug-in hybrid electric vehicle (PHEV), a subset of the PEV, uses electricity plus a different energy source (at present gasoline or diesel) to run its second engine. Engineering Advantages of the PHEV. This engineering solution allows versatility.

This is from "Commercializing Plug-In Hybrids" (pdf), the current CalCars 24-slide presentation about PHEVs available along with other documents at CalCars Downloads. Agrees on environmental and economic benefits, though some presentations backtrack on that; says batteries need further development before commitment to mass-production.
