The 2007 Toyota Prius is a full-featured midsize car that just so happens to be the most fuel-efficient car on the market.
The heart of the original Toyota hybrid car is a gas-electric drivetrain the company calls Hybrid Synergy Drive. In the Toyota Prius, the setup consists of a 1.5-liter four-cylinder gasoline engine paired with an electric drive motor that draws power from a nickel-metal hydride battery pack (mounted under the car's rear hatch area) -- together they make 110 hp. A second electric motor functions solely as a generator, recharging the batteries. The primary electric-drive motor can also rejoice the cells, using energy recaptured during braking. It sounds complicated, but a simplified continuously variable transmission (CVT) deftly shuffles power between the sources, providing smooth, seamless operation from the Prius driver's point of view. The Prius' claim to fame is its ability to operate under electric power alone at low speeds, which contributes to its low fuel consumption. With a combined EPA rating of 55 mpg, this is the most fuel-efficient car on sale in the U.S. for 2007.
As technologically sophisticated as the Toyota Prius is, it's a remarkably practical car to drive on a day-to-day basis. Its interior is spacious enough to accommodate a family of four in comfort, and a tight turning radius combined with light, the electric-assist steering makes it extremely easy to maneuver in crowded urban areas. The one thing the Prius doesn't offer is excitement, as its frugal drivetrain and modest handling capability make it one of the most tepid midsize cars on the road. This likely explains the introduction of the '07 Prius Touring model, which should provide slightly crisper handling along with a sportier look. If you're shopping for a Prius, you should also consider the similarly priced Honda Civic Hybrid. Its acceleration is equally pokey, but it has better road manners and more mainstream styling. For those who can spend a bit more, Toyota's own Camry Hybrid offers a larger interior and all the comforts of a regular Camry. If you want to wear your green commitment on your sleeve, though, there's no better choice for a hybrid car than the 2007 Toyota Prius.
