雷克萨斯HS 250h    

Lexus HS 250h

    《消费者报告》把雷克萨斯（Lexus）HS 250h油电混动轿车与讴歌（Acura）的TSX基本款进行了对比，后者是一款四缸发动机轿车。讴歌TSX的油耗为每加仑25英里，雷克萨斯HS 250h为每加仑31英里。不过雷克萨斯的售价不到4万美元，它的五年拥有成本大概在4.45万美元左右。讴歌TSX的价格约为3.07万美元，五年拥有成本约为4.1万美元。由于这两台车的燃油经济性相差不大，因此雷克萨斯HS 250h的车主必须开上8年，才能在拥有成本上战胜讴歌TSX。不过如果油价飙升到每加仑11.5美元的话，那么这个周期就会缩短成一年——不过那么高的油价实在太恐怖了。

宝马335d

    Consumer Reports compared the Lexus HS 250h gas-electric hybrid against Acura's TSX base model with a four-cylinder engine. The Acura gets 25 miles per gallon, the Lexus 31 miles per gallon. But the Lexus costs just under $40,000 to buy and $44,500 to operate for five years; the Acura costs about $30,700 and $41,000 to operate. Given the fairly narrow advantage the Lexus has in terms of fuel economy, an owner would have to keep the Lexus for more than eight years to overcome the cost disadvantage. If gasoline were to rise to more than $11.50 a gallon -- a dreadful thought, everyone can agree -- the payback period shrinks to one year.

BMW 335d

    宝马（BMW）3系由于其质量、运动性和出色的做工而受到了车主和评测人员的一致褒奖，不过大家很少表扬它的燃油经济性。现在宝马3系又推出了一款柴油动力版，名叫335d。它的起价约在5.19万美元，比汽油动力的328i差不多整整贵了1万美元，而且养车成本也更高。335d每加仑柴油可以跑28英里，汽油版每加仑能跑23英里。柴油版的经济性需要在8年后才能超过汽油版。

    BMW's 3 Series has won raves from owners and plaudits from reviewers for quality, sportiness and excellent engineering -- but rarely for fuel economy. BMW is offering a diesel-powered variant, dubbed the 335d. The diesel model, starting at about $51,900, represents almost $10,000 more in purchase price than the gasoline powered 328i, and costs more to operate. The diesel gets 28 miles per gallon of fuel, while the gasoline models gets 23 miles per gallon. After eight years of ownership, the diesel starts to be a better deal financially.
