From this report (2 page pdf press release) by T&E.
Of course, it is easier for manufacturers focusing on smaller cars to meet the targets, but that's the whole point: bigger cars pollute more, full stop. And Volkswagen foray into big SUVs and top of the line cars shows (conversely, Mercedes' move towards smaller cars like the A and B-series is paying off, but they start from far away).
The goal is to reduce absolute levels of pollution, not relative levels. Smaller cars across the range are needed.
