Regular readers here at Greenpacks will know that I am putting up a bunch of post/pics from my recent gallivant to the 2008 San Fran Auto Show.

There was more than one display that kind of caught my eye. I was looking for a green cars, eco-friendly cars, that sort of thing. Cadillac had a rotating display of its Luxury Escalade SUV stating it was confident enough to talk about fuel efficiency in the same sentence as luxury, SUV and big big car. And no Britney Spears …

They claim that the world’s first full-size luxury hybrid SUV, their 2009 Cadillac Escalade Hybrid, gets better mileage than the Mini-cooper. With a 332 hp V8 engine that generates 367 lb-ft of torque at 4,100 rpm they claim they seat more than 4 adults luxuriously and still get 20mpg … in the city!

But, what about all the hardware that went into making this monstrosity? Never mind that I suppose. At least, Cadillac is using the right buzzwords and aiming in the right direction, eh?

A few days ago Britney Spears spent some quality time together with her kids in Studio City, California and to be honest we’re really glad she’s getting her act together. What’s even more interesting to us greenies is that her Cadillac Escalade low rider has a groovy electric engine. Could that be the only vehicle she’s allowed to drive without supervision or that she cares about the CO2 emissions and the environment?

What’s with all these celebrities going green?
