Cameron Diaz To Take BMW's Hydrogen 7 To Oscars
As expected, some celebrities are opting to avoid Chevy’s fleet of fuel-friendly SUVs in favor of their own green transportation alternatives. One such gal is actress Cameron Diaz, who has decided to hitch a ride to the red carpet in BMW’s Hydrogen 7 sedan. This is the same car that’s currently being tested by the likes of Jay Leno, Will Ferrell, Jeremy Piven, and Edward Norton for everyday use. We also spied Brad Pitt and Angelina Jolie arriving to the premiere of Ocean’s 13 last year in the H7. Here’s what ABG has to say about this liquid-hydrogen powered vehicle:
“The H7 is a equipped with a dual fuel system that allows the V-12 engine to run on either gasoline or liquified hydrogen. Like other hydrogen-fueled internal combustion vehicles the H7 emits pretty much only water (and some trace amounts of NOx) when it’s running on hydrogen. BMW’s decision to follow the internal combustion path allows them to utilize their engine expertise, but the result is far less efficient than a fuel cell. Using liquid hydrogen also allows them to carry more hydrogen on board, but the insulated storage tank is much larger and heavier and the hydrogen boils off and must be vented to atmosphere.”
As with any vehicle taking advantage of hydrogen as a fuel source, there are still many problems yet to solve — the least of which is how to create hydrogen in a clean, energy-efficient manner. For more on the H7, check out BMW’s official site.
