Life in the Green Lane

Life in the Green Lane - New York Times

The car that started the hybrid craze, the Toyota Prius, is lauded for squeezing 40 or more miles out of a gallon of gas, and it really can. But only when it's being driven around town, where its electric motor does its best and most active work. On a cross-country excursion in a Prius, the staff of Automobile Magazine discovered mileage plummeted on the Interstate. In fact, the car's computer, which controls the engine and the motor, allowing them to run together or separately, was programmed to direct the Prius to spend most of its highway time running on gasoline because at higher speeds the batteries quickly get exhausted. Indeed, the gasoline engine worked so hard that we calculated we might have used less fuel on our journey if we had been driving Toyota's conventionally powered, similarly sized Corolla — which costs thousands less. For the owner who does the majority of her driving on the highway, the Prius's potential for fuel economy will never be realized and its price premium never recovered.
