The soaring and unpredictable cost of gasoline has undoubtedly fueled a rise in popularity for alternatively-powered vehicles.
When it comes to gas-electric hybrid vehicles, it appears that Toyota has done their homework. Toyota’s Prius became the first five-passenger gas-electric hybrid vehicle offered in the U.S. when it launched six years ago. Four years later, Toyota launched the second generation of the Prius. That’s impressive when you consider that many manufacturers haven’t even launched a competitive model to the Prius.
Soon there will be other players in this arena, but Toyota will continue to have more experience. Today, Prius is the best-selling gas-electric hybrid vehicle in the U.S. and demand continues to exceed supply.
Toyota’s hybrid system, now known as Hybrid Synergy Drive, is a full hybrid system, which means it can operate in gas or electric modes, plus a combination of the two when extra power is needed.
Prius is a smart-looking and aerodynamically efficient sedan, but its most impressive feature is that it averages better than 50 miles per gallon of gasoline.
Under Prius’ hood is a highly efficient gas engine combined with an advanced electric motor. The 1.5-liter gasoline engine produces 76 horsepower and the 50,000-W electric motor is rated at 67 horsepower.
When combining the gas engine and electric motor, the Prius produces 110 horsepower. Power is sent to the front wheels through an electronic planetary gear-type continuously variable transmission.
A regenerative braking system further boosts system efficiency. When the Prius is coasting or the brakes are applied, the electric motor functions as a generator, capturing kinetic energy that would normally be lost as heat through the brakes and transforming it into useable electricity to recharge the batteries.
One of the most remarkable features of the Toyota Prius is how well the computer-controlled powertrain seamlessly blends power from the gasoline engine, the electric motor and the generator.
I especially like the instrument panel’s color screen that allows the driver to monitor electric-gas power distribution, as well as instant and average fuel economy values.
I found the display quite useful as it forced me into adjusting my driving habits to try and achieve a high-score, er, high fuel economy. In case you’re wondering, I averaged 43 mpg over 100 miles of city-highway driving (high score 43!).
You might find it interesting to know that there are “hardcore” Prius owners out there who are posting their fuel economy on websites.
When stopped, the Prius’ gas engine turns off. During initial acceleration there is a slight lag, but we must emphasize that there’s plenty of power when needed.
There’s a noticeable increase in fuel economy during stop-and-go driving as the gas engine stays off below 20 mph, as long as the throttle isn’t pushed too hard.
This second-generation Prius is quite roomy and comfortable. The Prius offers amenities expected in the mid-size class, plus some available options more commonly found in luxury models.
Already featuring a high level of safety technology, Prius gains even more for 2006. There’s a new advanced airbag system, tire pressure monitoring system and optional rear back-up camera.
With a host of standard amenities and a starting price around $22,000, Prius is a viable alternative to other mid-sized sedans. Those with more refined tastes will appreciate the availability of leather-trimmed seats, JBL sound system and voice-activated navigation system. A fully loaded Prius costs just under $30,000.
Maybe slightly higher in price than other comparably priced cars, you must ask yourself the real cost of not looking for alternative fuel and auto options and facing the ever-warming planet’s response.
