Hollywood's elite brought green to the red carpet in some of the most modern and luxurious eco-friendly vehicles on the market.

Who's wearing who isn't the only arbitrary measure of celebrity magnitude at the Oscar's. There's also who's driving what. And for some lucky celebrities, arriving at the popular Hollywood Dominos 4th Annual Gala was an opportunity to show that an eco-friendly needn't diminish the glam.

Mercedes-Benz ensured the swift and safe arrival of celebrity committee members and attendees in S400 Hybrid sedans. The luxurious S-Class hybrid provides an estimated 30 miles per gallon on the highway and features the world's first lithium-ion battery in a production hybrid vehicle.

The Hollywood Dominos crowd also got an up-close look at one of the limited number of Zero Emission B-Class Hydrogen Fuel Cell vehicles that are now available for lease in California. Mercedes-Benz delivered several B-Class hydrogen fuel cell vehicles including one to the uber-eco conscious Executive Director of the Producers Guild of America, Vance Van Petten.

The vehicle is essentially an electric car that is fueled by compressed hydrogen, which gets the equivalent fuel mileage of 86.6 city-highway miles per gallon with a range of up to 240 miles, can be re-fueled in approximately 3 minutes and produces water as the only emission.
