Fast forward 10-15 years, they're far more stricter hence why so many turbocharged engines suddenly are showing up in mainstream cars. Lotus would still be using the old 2ZZ-GE engine...but its failing modern emissions and as a result they had to drop it. Going with direct injection is currently the easiest way to increase power while at the same time reducing an engine's emissions. Why do emissions matter to a automaker or owner? In some countries its actually taxed, this is why some American cars like the Mustang simply avoid those countries(for the 2015 Mustang only the 2.3L Ecoboost will be available to world markets) or in the case of Chevrolet and its Camaro...it turns a affordable car...into a more expensive car.

dont forget the use of multiple cam profiles. thats a pretty big deal if you ask me.
