A lot of the Prius's appeal is its 44-mpg overall fuel economy and ultraclean emissions. But it also provides a roomy interior, hatchback versatility and admirable road manners. Although relatively small on the outside, the long wheelbase and efficient space utilization give it interior room comparable to that of a midsized car. On the downside, the unusual control layout and gauge cluster may be confusing to some and the electric steering lacks feedback.
