If BMW were really worried about the gas prices, why do they keep making bigger engines?
I may be too optimistic but I think BMW may be making press statements about concernes over gas to make hearts and minds happy while doing the opposite.
I watch thier model lines closely and see no slow down towards making larger engines.
Now, if they can make thier engines more gas efficient then no one should stand in thier way as long as it doesnt coe at a performance cost. They have been doing this effectively well over the last 15 years. The 6 cylinder engines they have produced over the last 10 years have had better power output while also reducing gas consumption. You get newere engines with larger displacement. 2.3, 2.5, 2.8, 3.0, 3.2, and 3.5 Litre 6 cylinder inlines getting progressively more HP while consuming less gas due to technology refinements.
If you compare the 1996 328 to the 2002 328 you'll see more power gain in the newer model 328 but you'll also see no difference in gas consumption MPG city highway. They have the same displacement nad gas consumption but have made the torque and HP better.
