No one's talking about it, but the 2008 Chevrolet Tahoe Hybrid and 2008 Mercedes-Benz GL320 CDI are the two most fuel-efficient full-size SUVs on the market. We guess that makes Paris Hilton, proud owner of a 2008 GMC Yukon Hybrid, the hybrid Tahoe's twin, a forward-thinking early adopter at the vanguard of the green car movement.
Truthfully, calling either of these SUVs "green" might border on an insult to the color, not to mention the movement. These are still large, comfortable vehicles with more torque than the average commuter needs and more seats than most families will use, perfect for vacations but decadent in daily life.
But these vehicles are more reasonable when you consider that the four-wheel-drive 2008 Chevrolet Tahoe Hybrid earns an EPA rating of 20 mpg city/20 mpg highway, and the all-wheel-drive 2008 Mercedes-Benz GL320 CDI rates 18 mpg city/24 mpg highway. This works out to a combined rating of 20 mpg for both SUVs — a big achievement for a full-size sport-utility.
When it comes to large sport-utilities, think of this as a practicality test for hybrid and diesel. In other words, if you want to drive something big without feeling bad, this is what it's all about.
