当2008年雪佛兰Tahoe两模式混合动力车被“年度绿色汽车”评选为 绿色汽车杂志 last November, a lot of folks scratched their heads. Sure, the super-sized hybrid boasts relative benefits over comparably sized gas-powered SUVs, but is that enough to regard the 塔霍杂种 as eco-friendly? The official EPA fuel 经济omy ratings are 21 in the city and 22 on the highway, which represents a 30 percent increase in overall 经济omy, and a 50 percent improvement in city driving.
We had an opportunity to drive the 塔霍杂种 over the last few days, and to conduct two separate real world mileage loops in order to determine the vehicle’s fuel 经济omy. The first was a highway drive from Cape May, New Jersey to Falls Church, Virginia. The 238-mile stretch ate through a little more than three-eighths of the 24.5 gallon gas tank, and yielded just over 21 miles per gallon, right on par with EPA estimates. Driving style was on the conservative side, as the vehicle stayed in the right hand lane for most of the road trip.
The 雪佛兰 塔霍杂种, powered by its 6-liter V-8 gas engine in conjunction with electric motors, surpassed expectations for efficiency. For those who cannot live without a large vehicle, the Tahoe delivers the promised fuel 经济omy. But the question still lurks: Is that enough to call it a green car, much less the “年度绿色汽车？ ”
