When car buyers think of hybrids, the name that most often springs to mind is the Toyota Prius since it was the first really practical hybrid to come to market and has sold more than any other examples. Yes, of course, the original Honda Insight beat the Prius to market in the U.S. by about six months, but the tiny two-seater sold in equally tiny numbers and had limited appeal beyond hard core hyper milers.
In the coming weeks, Toyota dealers will start getting their first allotments of the all-new third-generation Prius, and while we got to spend a few hours with one on the west coast in March, we just spent a whole week with the new version of this iconic Toyota. While the efficiency of the Prius has never been in dispute, like many other cars from Brand T, its appeal as a driver's car has been, to say the least, limited. For its generation three model, Toyota has not given up on minimizing fuel consumption, but it has sought to make the Prius a bit more appealing on other levels. Read on to find out if the company has succeeded.
Many of the most avid fans of the Prius have been people who view cars as nothing more than a means of conveying occupants to a destination with the least amount of fuss. Minimal fuss often means minimal involvement, as well. That typically means finding the most direct route with the fewest number of directional changes. For those operators (we hesitate to call anyone who prefers to remain uninvolved in the process a driver), the first two generations of the Prius were utterly up to the task.
However, there is a fringe group of us who actually prefer roads with some twists and turns and enjoy the challenge of carrying momentum through corners without scrubbing off speed. Doing that effectively is aided by a car that transmits information about cornering forces back through the steering wheel and doesn't feel like it will scrape its door handles at moderate speeds. This is where the previous Prius was severely lacking, falling far short of other thrifty vehicles like Honda's new Insight and VW's Jetta TDI.
Somehow, Toyota has managed to muster its prodigious resources over the last several years to create a new model to address both of these extremist camps. Under the hood, the Prius now includes the latest iteration of Hybrid Synergy Drive, which operates more efficiently than ever. The basic architecture has not changed and includes an electronically variable transmission that acts as the power split device and a pair of electric motor/generators to provide drive torque and kinetic energy recovery.
The internal combustion engine remains a four-cylinder running on the Atkinson cycle to optimize its thermodynamic efficiency. However, the displacement has grown from the previous 1.5 liters to 1.8 liters, which has dual benefits. When the driver actually needs extra power in order to merge onto a freeway or complete a passing maneuver, the propulsive force is now readily available. The extra displacement means that it's available without unduly straining the engine so the impact on fuel consumption is actually reduced.
Inside, the new floating center console features a trio of buttons to help manage the powertrain behavior, one of which was previously available only in overseas markets. For the first time, U.S. Prius buyers now have an EV button available that sometimes allows the driver to force the car into electric drive mode. Since the Prius is designed as a parallel hybrid, the electric drive portion of the vehicle has limited capabilities (although far more than most current hybrids) to drive the vehicle. Therefore, the EV mode only allows the Prius to troll around silently at speeds below 25 mph. Of course, you can get kicked out of EV mode if the battery level is too low or the accelerator is applied with too much verve. With sufficient energy in the battery and an extremely light right foot, we were regularly able to go over a mile without the engine firing up.
