Q:Did you consider applying variable valvelift to your l.O-litre turbocharged gasoline engine? A:We did think about it, and we'd never exclude anything in the future, but the point with variable valvelift is that it helps you most if your engine is too large. On an aggressive downsizing concept like the 1.0 Ecoboost you're getting diminishing returns because you're addressing pumping losses - there's not much left in terms of pumping losses on a 1.0 engine.
