What does DI stand for? Is this some sort of next-gen Valvetronic?

Direct Injection.

I think direct injection engines are the new direction BMW is heading, which offers way better fuel economy and emissions. Look for some turbo DI engines as well.

Right now the only engines that are DI are the diesels, naturally, and the jointly produced pterol I4 from BMW/Peugeot. BMW is heading in the direction of producing more DI petrol engines.

Audi and Lexus are already having good success with their fairly newly released engines. The Lexus actually uses a stratified charge. It has injectors in the manifold as well is in the combustion chamber. I read an excellent SAE article on it recently. I'll try to scan it sometime time in the next few days and post it.

The main advantage with DI is a better mixture, which results in better torque, fuel consumption and emissions.

Direct refers to directly into the combustion chamber, exactly like a diesel.

The Valvetronic six that was released two years ago was an interim engine, as the DI models weren't ready for production. Our current X5 models have the M54 3.0 six, the N52 is the 255 hp 3.0, and the N53 will have the same hp, but another quantum leap in fuel economy (same order of magnitude as Valvetronic gave us), with similar emissions. They could go for very low emissions, but that would compromise the power. They are designing to the same power for equivalent displacement as today's Valvetronic models.

BMW has announced that all models will move to direct injection in time.

BMW has DI engines in production today, just not the I6 or V8. The 760 uses direct injection, but without a stratified charge.

The N54 is the Valvetronic/DI/Turbo version of the I6. All the good stuff.

Apparently, this is a photo-chop.

The photo is showing the new model in full showroom trim. Power for the CC comes from a variety of six-cylinder engines ranging from 2.2 litre 180 HP to 3.0 litre 258 HP. The top of the line M3 will get a V8 4.0 litre engine delivering around 400 HP. Furthermore three Diesels will be available performing 163 HP to 272 HP
