10. Mercedes-Benz GL350 BlueTEC
If you’re going on a long-distance trip with a group of people a few things are important. Naturally interior space for both passengers and luggage is critical, as is comfort. But you can’t afford to forget about fuel economy, either.
The Mercedes GL350 BlueTEC is a large sport-utility vehicle that’s powered by an efficient and clean-running diesel engine. Displacing 3.0-liters it delivers 240 hp and a monstrous 455 lb-ft of torque. The compression-ignition powerplant is matched to a seven-speed automatic transmission and the company’s 4MATIC all-wheel-drive system. As for efficiency, the BlueTEC GL stickers at 19 mpg city and 26 highway, damn-impressive figures for a gigantic SUV.
