Wow... that thing really is
 

Wow... that thing really is clever... *rimshot*.

Seriously folks... Tip your waitress.

Anyway, it looks like these manufacturers are taking MPG seriously.

i wouldn't say that until
 

i wouldn't say they're serious until you can buy one!

speaking of serious, it was reported recently toyota is now acknowledging publicly that they're researching plug-in abilities for their hybrids. that's encouraging. they've been dismissing the idea up until now.

Re: i wouldn't say that until
 

This is sooner than expected. I was expecting hyrbids to be the norm before plug-in hybrids were going to be given serious consideration.

The BMW Clean Energy system involves liquid hydrogen produced from water using solar power. Hydrogen as a motor fuel is the answer to many environmental problems since there are no harmful emissions, no depleting of resources, and no danger to the atmosphere.

The 745h continues in the tradition of BMW hydrogen powered vehicles.

The 745h is powered by a 4.4-liter V8, featuring bi-VANOS variable valve timing, Valvetronic variable intake runners, and a fully variable intake manifold. The 745h can use either hydrogen or premium unleaded gasoline.

Running on hydrogen, the 745h produces 184 horsepower and can achieve a top speed of 133 mph. The cruising range is 190 miles. Added to the 400-mile range of the normal fuel tank, the 745h can go 600 miles between fill-ups.

An Auxiliary Power Unit (APU) runs the 745h's power-consuming features. The APU operates on a Polymer Electrolyte Membrane (PEM) fuel cell that is independent of the engine, thanks to a direct hydrogen feed from the trunk-mounted tank. This means power accessories like air conditioning can be operated when the engine is shut off, saving a gallon of gas for every 235 miles of city driving.
