Slightly off topic, but I always wondered this about fuel economy. Since the main driving reason for BMW is to be green, I thought I'd ask this question here. Forgive my lack of knowledge.

A V8 engine is two I4 engines bolted together in V shape. Could it be possible to use only one of the I4 banks for let say cruising? If possible, I think that'll be 'green'. We'd have the full V8 for normal usage. And manually or automatically (which can even be programmed in to M drive), we can switch to single I4 mode for high way cruising...
