2010 Toyota Prius

The 2010 Toyota Prius has been fully redesigned. Key improvements for this third-generation model include more power, better fuel economy, enhanced steering feel, more conventional interior controls and sleeker styling.

Introduction

The last Toyota Prius flipped the automotive world on its head, changing the purchasing priorities of American car buyers seemingly overnight. Attracted to its sky-high fuel economy, practical body style and green image, consumers came to the Prius for many new car searches (regardless of their actual motoring needs). What was once an automotive oddity relegated to hemp-wearing greenies, the Prius grew to become the country's 13th-best-selling vehicle in 2008. Now there is the all-new 2010 Toyota Prius. It's poised to keep the hybrid revolution going, but with key changes to make it more appealing to an even wider audience.

A quick look at the 2010 Prius will reveal a familiar shape, but it's a little sleeker and a tad (dare we say) sportier than its predecessor. Visually, it looks smaller, but it's an optical illusion that creates a more streamlined appearance. Indeed, the 2010 Prius is less than an inch longer and wider than last year's model. The interior is a different story, as headroom has been reduced by a fraction of an inch. This wouldn't seem to be a big deal, but in our testing we found that taller rear seat occupants had their hair grazing the roof, and that wasn't the case before.

Under the hood resides a revised version of Toyota's Hybrid Synergy Drive. There's a larger and more powerful gasoline engine now, but instead of providing quicker off-the-line acceleration, it allows more effortless highway cruising. A smaller electric motor contributes less torque to the overall powertrain dance, but it improves efficiency. There are other mechanical changes, too, but the end result is a jump in fuel economy, from last year's EPA-estimated 48 mpg city/45 mpg highway to this year's 51/48 mpg.

Toyota has also addressed other previous Prius faults. A more rigid chassis and a revised electric-assist steering system help to improve steering feel and driver confidence -- the old Prius' steering had a disconnected, video-gamelike feel. While the Prius still isn't exactly fun to drive, its straight-line stability is a lot better now, and in general it feels more like a normal car.

The latest Prius might even seem like a small, ultra-efficient luxury sedan depending on how you equip it. Luxury-themed items like heated leather seats, a solar-powered sunroof (cools the interior when parked), a navigation system, radar-based adaptive cruise control (matches your speed to the car ahead), a pre-collision system (retracts seatbelts and applies the brakes if a crash is unavoidable) and a lane-departure warning system for inattentive drivers are all available. Also, the automated self-parking system you've seen in Lexus commercials makes its way onto the Prius' options sheet.

The Prius has been a huge success, and with such success comes added competition. The all-new Honda Insight looks similar to the Prius, has similar fuel efficiency and costs less, but it's smaller and less sophisticated. The Ford Fusion Hybrid's more traditional body style and more involving driving dynamics should appeal to those who want their hybrid to be a little more like a normal car. The Camry Hybrid is another possibility, as is the limited-availability Altima Hybrid. Regardless, when it comes to an ultra-practical, ultra-efficient automotive choice that, depending on equipment, can be anything from an economy car to a luxury car, the 2010 Toyota Prius cannot be beat.

Body Styles, Trim Levels, and Options

The 2010 Toyota Prius is available in four trim levels that should appeal to an ancient Roman's sensibilities: Prius II, Prius III, Prius IV and Prius V. The Prius I will be released later at a lower base price. Standard equipment on Prius II includes 15-inch alloy wheels, full power accessories, keyless ignition/entry, auto on/off headlights, cruise control, a height-adjustable driver seat, a tilt-telescoping steering column, a hybrid system display and a six-speaker stereo with CD player and auxiliary audio jack. The Prius III adds Bluetooth and an eight-speaker upgraded stereo with six-CD changer. The Prius IV has this equipment plus additional exterior locking buttons for keyless entry, leather upholstery, heated front seats, driver lumbar adjustment and an auto-dimming mirror. The loaded-up Prius V comes with 17-inch alloy wheels, foglamps and LED headlamps with auto-leveling and washers.

The Navigation package available on all but the Prius II includes a voice-activated touchscreen navigation system with real-time traffic, a back-up camera, a four-disc CD changer (replacing the six-slot) and Bluetooth music streaming. The Solar Roof package can be added to the Navigation package and includes a sunroof with a solar-powered ventilation system that cools the car when it's parked. The Advanced Technology package when added to the Navigation package includes adaptive cruise control, pre-collision alert system, a lane departure warning system and automated self parking.

Powertrains and Performance

The 2010 Toyota Prius is powered by Toyota's advanced gasoline-electric hybrid powertrain. A 1.8-liter four-cylinder engine combines with a pair of electric motors (one for propulsion, the other an electrical systems generator) through a planetary-type continuously variable transmission (CVT). The result is a total system output of 134 horsepower. In track testing, we clocked the Prius going from zero to 60 mph in 10.1 seconds, which is roughly the same as the old car and a few ticks quicker than the Honda Insight. The most important number, however, is fuel economy. The EPA estimates the 2010 Prius will return 51 mpg city/48 highway and 50 mpg combined. That's the best fuel efficiency of any mass-market vehicle sold with an internal combustion engine.

Safety

Every 2010 Toyota Prius comes standard with antilock disc brakes (the old car had rear drums), stability and traction control, front side airbags, side curtain airbags and a driver knee airbag. Optional equipment includes a pre-collision warning system and a lane-departure warning system. In brake testing, the Prius stopped from 60 mph in a short 118 feet, with less fade than the previous rear-drum-equipped car.

Interior Design and Special Features

The 2010 Prius features straightforward climate and audio controls that jut out toward the driver in a "floating console" that provides a storage area underneath. This is an improvement over the convoluted touchscreen controls of the old Prius. Unfortunately, the materials used in the 2010 version are a step down, with harder and cheaper plastics throughout. The corduroy-like texturing on the climate and audio controls seems nice at first, but after only a few days, finger oils cause circular dark spots on most buttons. Another issue is the off-center digital gauge setup that buries the speedometer and fuel meter amidst a sea of less vital information.

In terms of versatility, though, the Prius is still a champ. The hatchback body style provides more cargo capacity than a typical midsize sedan, while its backseat provides lots of space (although headroom is a bit less now). The rear also seems to have less legroom than before, but that's because the front seats thankfully have more legroom. As for the front seats, the addition of driver height adjustment is a benefit for both short and tall drivers. Sadly, the latter still have to contend with a steering wheel that's placed too far away -- there's a telescoping column now, but it doesn't come out nearly far enough.

Driving Impressions

The 2010 Toyota Prius retains its hyper-quiet cabin, made possible by its part-time electric motivation and plenty of sound-deadening materials. The ride is also quite comfortable, and for 2010, the Prius' structure is tauter, resulting in a less flimsy feel when the car is driven over road imperfections. Another pleasant improvement is the electric steering system, which feels more substantial and better connected to the front tires while still being user-friendly in parking lots.

In regard to its hybrid powertrain, new driving modes (EV, eco, power and normal) allow the driver to decide how the car's powertrain should be configured for the driving scenario at hand. Eco is decidedly sluggish, but certainly gets the best fuel economy. You'll want to select power for freeway on-ramps or driving in hilly environments. The EV mode locks out the gasoline engine, but only up to 25 mph with at least a half-charged battery pack.
