As with many of Toyota's vehicles, the Prius has become a standard-bearer in its segment. While many automakers have yet to even develop a gasoline-electric hybrid vehicle, Toyota is already on its third generation of the Prius. This four-door hybrid has become a hit with consumers because of its stellar fuel economy, relatively uncompromised driving and acceleration characteristics and reasonable price.

The Toyota Prius (its name comes from Latin and means "to go before") exists as a partial solution to the automobile's problem of tailpipe emissions. The Prius, like other hybrid vehicles, has a special powertrain that combines a gasoline-fueled internal combustion engine with an electric motor. This powertrain, along with other advanced features, allows the Prius to deliver higher fuel economy and lower emissions compared to regular cars.

Due to its popularity and relatively long sales history, Toyota's original hybrid car is a strong candidate for a shopper interested in a used hybrid vehicle. So far, it seems Toyota's reputation for reliability and durability is holding true for the Prius.

Current Toyota Prius

The Toyota Prius was completely redesigned for 2010. However, it remains a four-door hatchback that seats five people. The car's hybrid powertrain consists of a 1.8-liter gasoline engine that produces 98 horsepower and 105 pound-feet of torque that's used in conjunction with two electric motors and a special planetary gearset that functions as a continuously variable transmission (CVT). Total system power is 134 hp.

Under full acceleration, both power sources work together to provide maximum oomph. But under lighter load conditions such as stop-and-go traffic, the Prius alternates between the two, often running on battery power alone. This maximizes the car's fuel economy potential. A regenerative braking system converts energy normally lost as heat into electricity to charge the car's battery pack. The current powertrain is a little more robust on the highway than the previous-generation car, although not really any quicker away from a traffic light. It is more fuel-efficient, however, with an EPA combined fuel economy estimate of 50 mpg -- which is tops in the hybrid game.

Other changes for this new model include a more sculpted take on the iconic hybrid shape established by its predecessor. The interior was given a more radical overhaul, with a more conventional center control stack than the old car. The hybrid system display now resides high up on the dash next to the digital speedometer, while stereo and climate controls are laid out in a traditional manner with physical buttons rather than a touchscreen (which reappears if you order the optional navigation system). The result is a car that's easier to acclimate to. It's also a bit more comfortable for taller drivers, thanks to a height-adjustable seat and a telescoping steering wheel.

One thing that hasn't changed is the Prius' superb interior packaging, which helps extends the car's appeal beyond simple fuel efficiency. Its hatchback body style allows for an impressive amount of cargo to be lugged around, while a surprisingly commodious backseat makes it a plausible replacement for a family sedan or compact SUV.

In reviews, we've found the current Toyota Prius to build upon its revolutionary predecessor's successful formula of fuel efficiency and versatility. It's now a more normal car to drive and use, making it easier to transition from a traditional car.
