Sport:Life First Drive: 2010 Toyota Prius

In the foothills of Tucson’s Mount Lemmon, Toyota’s public relations staff delivered Utterli tragic news: a driving impression embargo would preclude live video microblogging coverage of the 2010 Prius. Crushed, I resolved to hike the mountain in the Prius anyway. Now that the embargo has passed, here are a few excerpts from my notes.

The Prius’s silhouette may be contentious, but two points can’t be argued: the aerodynamic shape serves its purpose well, and anything is a welcome alternative to typical Toyota anonymity. Unfortunately, that blandness has crept into the Prius’s front fascia. Toyota’s corporate slit-and-nub grille has been grafted onto the Prius, which offers little differentiation from the Corolla or Yaris from head-on angles.

Toyota pushed the roofline peak aft to increase headroom for backseat passengers. The new roofline’s funky bump gracefully cascades into a refined kammback. Standard energy-efficient LED taillamps integrate nicely with the functional rear spoiler in a handsome evolution of the Prius’s rear quarter.

Interior volume has increased, and is now within eight cubic feet of both the Camry and Fusion Hybrid. The Prius’s lack of ecologically-conscious upholstery and use of traditional petroleum-based seating foam may turn off some greenies, and the mostly staid interior design leaves only one thing to talk about: the Touch Tracer-actuated Multi-Information Display. Touch Tracer is Toyota’s name for touch-sensitive steering wheel controls replicated on the dashboard’s top tier. The redundancy is intended to keep drivers’ eyes on the road while scrolling through trip information screens. Like all Toyota and Lexus hybrids, the fancy dash lacks a tachometer. The monotone green display must be a tribute to Tron — the antiseptic graphs can’t compare to the Fusion’s focus on design. Judge for yourself:

Unfortunately, Toyota’s corporate navitainment head unit is nestled into the Prius’s dash. Drivers must choose between having radio presets at hand, displaying song and artist information, or displaying the navigation map. The world’s best systems share screen real estate — this interface is so poorly executed that the volume bar is not even skinned.

What makes the Prius livable are its on-road dynamics — and we’re not yet talking about fuel economy. To my shock and surprise, the pre-production Prius I drove was outfitted with an electronic power steering system with genuine weight. Every snaking segment leading to the summit of Mount Lemmon revealed an incredible truth: the Prius does not suffer from vapid wheel feel. Not once during the admittedly gradual 8000-foot climb did the Prius’s battery assist run out of grunt. The third-generation nickel-metal hydride system obviously works hard to recapture every possible electron during regenerative braking and coasting — and the proof is in the MPG.

Federal estimates say the Prius can travel 50 miles per gallon in mixed driving. As always, your mileage will vary. Dan Bryant’s sure did. The president of the Houston Hybrids and Hypermilers’ Club achieved 90.6 miles per gallon in the new Prius — one full mile per gallon more than the previous-generation car. To read his impressions, check out the EcoLLC.com blog.

During the pre-drive press briefing, Prius marketing director Doug Coleman said that the new Prius faces two major adversaries: the global economic downturn, and the aggressively priced Honda Insight. Coleman’s almost militant frankness could very well suggest a brewing price war. Any battle for hybrid supremacy will benefit green-minded buyers — and a truly affordable Prius could sway Camry buyers away from the beige and bland once and for all.

Here’s hoping.

Toyota Prius arrives in Detroit [Live photos added]

It’s the car that started it all. Back in 1997, Toyota introduced the original Prius, which was the first ever mass-produced hybrid-electric vehicle. The car’s name is a Latin word means “to go before” — in this case denoting a car that was the first in what the forward thinkers at Toyota thought would eventually become the norm. Twelve years later, Toyota is rolling out its third-generation Prius, redesigned for the 2010 model year.

For the most part, Toyota is still building upon the basic Prius concept. The car still has a quirky hatchback design, it’s still powered by relatively basic nickel-metal hydride batteries, and performance numbers will likely discourage enthusiasts.

But there are a number of solid improvements and clever new features that will serve to bolster the car’s following and potentially lure new customers. These include a moonroof with solar panels, four driving modes, Intelligent Parking Assist (IPA), and steering wheel touch controls. A multi-information display panel that monitors fuel and energy consumption is also standard.

The first-generation Prius was rated 41 EPA mpg, and the second-generation model pushed that figure to 46 mpg. The 2010 model marks another significant incremental improvement to 50 miles per gallon (combined city/highway).

A larger and more powerful 1.8-liter Atkinson-cycle, four-cylinder engine powers the car. Contrary to what one might think, the larger engine actually helps improve highway mileage. By making more torque, the new engine can run at lower average rpm on the highway.

An electric water pump and a new exhaust gas recirculation system also boost efficiency. Furthermore, the engine has no belts under the hood, resulting in better fuel economy and less potential maintenance. The new transaxle and inverter are both 20 percent lighter, reducing the car’s overall weight.

Weight was also saved through use of aluminum in the hood, rear hatch, front suspension axle, and brake calipers. Lighter steel is used in the rocker inner, center pillar, and roof reinforcement.

The new Prius will offer three alternative driving modes. EV-Drive Mode allows driving on battery power alone at low speeds for about a mile, if conditions permit. There is also a Power Mode, which increases sensitivity to throttle input for a sportier feel, and an Eco Mode, which helps the driver achieve the best possible mileage.

Other energy-saving features include available LED low beams and taillights, a more efficient air conditioning system, and a unique ventilation fan that promises to reduce the need for air conditioning in the first place.

The air circulator — which is powered by solar panels — prevents the interior air temperature from rising while the vehicle is parked. This, in turn, makes cool-down time shorter when the driver returns to the vehicle.

The air-conditioning system is also capable of running with the engine off, so the driver can adjust the interior temperature for comfort before getting in the car — an industry first.

Toyota says it listened to customer feedback, and sharpened handling, reduced road noise, increased interior volume, and improved acceleration. The zero to 60 mph sprint takes 9.8 seconds now — an improvement of over one second. Disc brakes are now used on all four corners, replacing the front disc/rear drum brakes in the current model.

Interior space has increased considerably, both by making the car larger and making the cabin design more efficient. The car is 0.4 inches longer and 2.2 inches wider. The battery cooling unit also takes up less space, providing more room for passengers. Rear legroom is further improved thanks to thinner front seats.

Dynamic Radar Cruise Control system is now an available option. The system also enables Lane Keep Assist, which helps the driver stay safely within the lane, and the Pre-Collision System, which retracts seatbelts and applies the brakes in certain conditions when a crash is unavoidable.

The next-generation Intelligent Parking Assist features simplified settings to help guide the car into parking spaces. A backup monitor, which provides a view of rear obstacles when reverse is engaged, is available with an optional voice-activated navigation system. Safety Connect, Toyota’s first safety and security service, will be available a few months after launch.

News Toyota Prius a Real, Live Car

Well, is my face red.

I like to pooh-pooh political correctness, and things apparently designed to appeal to the liberal mindset. Hence my built-in aversion to hybrid cars, which at first bloom seemed to be a case of pandering to the enviro-whacko fringe.

After all, Honda’s first hybrid, the Insight, was indeed a technological marvel, but so utterly impractical as anything other than a commuter vehicle — not that there’s necessarily anything wrong with that. The Insight sipped gas, but with only two seats and limited storage space — and anemic power — it wasn’t really a vehicle you could take into the mountain passes and expect pulling power. I know this because that’s exactly where I took it.

Look, I have nothing against hybrids as such especially as a techno guy. But hybrids seemed to up the gas mileage ante at the expense of the "fun to drive" I love so much, and at a price that means you’ll probably never recover the extra outlay unless gas prices approach the price of premium bottled water.

Then along comes the second generation Toyota Prius for review and I’m all set to dust off my political correctness jokes to pepper my column on the hybrid.

But then, this fantastic car blew me away on its own terms! Again, my face is red - or is it green?

Toyota, according to its website, says the Prius is "everything an Intermediate Sedan can and should be: powerful, responsive, accommodating, exceptionally fuel efficient and extraordinarily clean burning." And as it turns out, they’re right.

I should have known. Since I drove that first Insight, Honda’s Civic hybrid came along and it was a really nice ride that I could easily envision as a daily driver. Then Honda introduced a hybrid Accord that’s supposedly quicker than the gas-only version, while Lexus has begun marketing a beautiful and powerful hybrid version of its RX 330 SUV — and the second generation Toyota Prius has garnered all sorts of awards.

Something funny must be afoot. Hybrids have evolved into nice, practical vehicles, if pricey.

The Prius is a smooth, bubble-shaped beastie, looking kind of like how the Pontiac Aztek could have if it were smaller and had its sharp edges filed clean to make it graceful instead of angular. It slips through the air almost silently; in fact, the car’s entire operation is so silent it’s difficult to tell when the gas engine is running and when it isn’t.

The heart of the Prius’ drive technology is Toyota’s Hybrid Synergy Drive, which blends the gasoline engine with electric motor to deliver better power and fuel efficiency than you’d get if the car only used the gas parts. Toyota says it’s a "full" hybrid on the road, meaning that it operates in electric-mode only, gas-mode only or a continuously variable combination of the two. This, of course, is how it should be.

The gas engine is a 1.5 litre, 16 valve, dual overhead cam, variable valve-equipped 4 cylinder model that Toyota claims gives the power and performance of a mid-sized sedan. I don’t know about that: the gas engine is rated at 76 horsepower @ 5000 rpm and 82 lb.ft of torque @ 4200 rpm, which isn't a lot - but that's before you add the electric stuff.

The engine also helps qualify the Prius as a Super Low Emissions Vehicle (SULEV).

The permanent magnet synchronous electric motor is rated at 67 horsepower @ 1200 - 1540 rpm and 295 lb.ft of torque from 0 - 1200 rpm.

Get a load of that torque figure!

The hybrid system is run by a Power Control Unit that integrates both gas and electric power sources. Toyota claims the result is a 0-60 time of just 10.1 seconds — hardly sports car territory, but Toyota claims it’s comparable to the 0-60 time of its 160 horsepower, 4 cylinder Camry. I drove the 4 cylinder Solara — a Camry derivative — right after the Prius (though I didn't actually time either), and I’d have to agree that the claim sounds reasonable.

As with other hybrids, braking or coasting turns the resulting energy thus created (and usually wasted) into electricity that’s captured and used to recharge the battery. It’s an elegant system that works well.

Toyota claims the Prius will get 4.0 litres per 100 kilometres gas mileage in the city and 4.2 on the highway. I never approached those figures (there’s a readout on the dash that gives a running tally of your mileage), though for most of my week with the Prius I wasn’t trying to optimize my mileage — I wanted to see what the car could do besides sip petrol, so I drove it like I drive every car to see what it was made of.

And you know, this is a very nice car to drive! Sure, it’s no sports car when it comes to acceleration, but it’s surprisingly spry and, while it doesn’t really handle like a sports car either, it gave me a surprisingly satisfying driving experience. On my favourite loop into the Rocky Mountains and back, which includes plenty of long straight freeway stretches as well as lots of hills and twisty bits, it performed just fine.

I was blown away. Even on the return trip on the freeway, where I stuck it in cruise control at about 115 km/h, it held the speed beautifully up and down the foothills — and still got me an average of 4.9 litres/100 km, which for my driving style was outstanding. My mileage while driving the Prius as if it were a Champ car was still about 5.6 l/100 km, which is even more impressive as far as I'm concerned.

As with an increasing number of cars these days, Prius gets rid of the traditional mechanical "gas pedal mechanism", instead using an electronically controlled "drive-by-wire" system. Here, instead of a press of the accelerator automatically opening the throttle, your foot pressure on the accelerator sends an electronic message that you want some get up and go to an on-board computer. It works fine.

One thing you’ll notice right away when you get into the Prius is its gear selector. The Prius uses a continuously variable transmission, which doesn’t have conventional gears. The "gear" selector in this case is a little joystick-like device that defaults to a central position regardless of what "gear" you’re in. All you do is move the selector to your choice ("D" for Drive, "B" for engine braking — which is good for controlling your speed down hills — "R" for reverse and "N" for neutral) and then drive.

A CVT takes some getting used to, not so much in actually using it but because it seems weird to be driving a car that never shifts. This was my second experience with a CVT and I really like the way they balance performance with convenience. They seem to perform like a manual, but function like an automatic. The ones I’ve tried don’t give you the "pretend manual" feature of many conventional automatic transmissions, but that didn’t bother me as much as I thought it might.

The front engine/front wheel drive Prius features independent front suspension with MacPherson gas struts while the bum is slung by torsion beams; there are also stabilizer bars front and rear. Prius also gets Advanced Traction Control (TRAC), Vehicle Stability Control (VSC) and power-assisted ventilated disc brakes up front, with ABS and electronic brake force distribution. Steering is variable power assist rack and pinion.

Inside is a surprisingly roomy and comfortable cabin, with cavernous room for the people in the rear. From the driver’s perspective there isn’t a lot to complain about, either. Instrumentation, while digital, is clean and clear. The instrument panel is set below the leading edge of the windshield; I first thought that it was a really dumb idea to mount it so far away from the driver, but after driving the car for only a couple of minutes I realized it’s really a stroke of genius having the display set where you barely have to take your eyes from the road to read it.

In the middle of the dashboard you get the typical LCD screen that displays far too much information, including one of those damn lawyer screens that are becoming the bane of the car industry. The instrumentation/screen and the features in my test unit were quite high end, reminding me not a little of the setup in the Lexus GS 300 AWD I drove a while back.

Even the in-dash 6 disc CD changer audio system is very good, though unlike the Lexus it won’t take DVD-Audio or dts discs. Like just about everything else about the Prius, however, the quality of the audio is much better than I expected.

But of course it isn’t perfect. The "info" button on the steering wheel seems to operate different functions than the one on the LCD panel and some of the other stuff controlled via the screen aren’t particularly ergonomic. And the "smart" keyless entry that lets you keep the fob in your pocket (the car starts via a push button on the dash) wasn’t any smarter than the Lexus one I tried — which means both of them are "intellectually challenged" compared with the system in the Infiniti M35x. To be fair, however, the Toyota system worked better for me than the Acura RL’s.

The greenhouse is excellent, except that the driver’s side "A" pillar gets in the way of the view sometimes. But overall there’s plenty of glass and blind spots are at a minimum.

There are plenty of storage spaces, too, including an interesting double glove compartment, and the car’s configured as a hatchback that features fold down rear seats, so there’s plenty of room for hauling stuff as well.

Safety features are what you’d expect from a modern car, including dual stage front airbags with optional front head and curtain side airbags with front seat side mounted airbags. All five passengers get 3-Point seatbelts while the driver and front passenger seatbelts also feature a pre-tensioner which takes up any slack at the moment of impact. A force limiter reduces the belts’ tension to decrease pressure on the passenger’s torso.

There’s more, of course, including automatic HVAC, but you get the idea. The Prius is for real.

It’s not cheap, though. The base model, which is still pretty nicely loaded, starts at $30,530 Cdn/$20,975 US. My handsome, fully loaded "Seaside Pearl-coloured" tester tipped the cash register at about $37,945 Cdn/$26,629 US.

Okay. I’m convinced. The Prius is a very nice car on its own, regardless of whether you want to save gas (or the environment) or not. But if you’re thinking of jumping into the hybrid market remember: you pay a premium over their gas powered brethren, so much so that you may never see any cost savings during your time with the car.

But hybrids are very green, and they are very nice.

Toyota Prius puts up BIG numbers


2010 Toyota Prius – Click above for high-res image gallery

When you sit in the 2010 Toyota Prius, you notice all those little things that provide the "Prius experience" – the shift lever, information screen, center-mounted instrument panel – are all present, but they're slightly different and noticeably improved. The time it takes to adapt to the revised interior is emblematic of the new Prius experience. It's the same oddly shaped hybrid that almost two million buyers love, but it gets better mileage, looks sharper and is packing more technological whiz-bangery than any vehicle this simple to drive has the right to.

We recently tested the 2010 Prius at its North American launch through the vineyard-covered fields and hills surrounding Napa, California. Through it all, the hybrid, officially rated at 50 mpg, performed well and delivered better-than-expected fuel economy. In fact, when we pushed the car's eco prowess by using the EV mode as much as possible and employing a few other tricks, we blew that EPA estimate out of the water by almost 15 mpg. And we weren't alone.

The Prius' chief engineer, Akihiko Otsuka, drove a 33-mile route in and around Napa and averaged 62.9 mpg. During the drive week, he levied a Beat-The-Chief challenge to anyone who wanted to take him on. AutoblogGreen was able to get the in-dash display to read in the mid- to low-70s for most of the route, but the last ten miles on a busy 55-mph road dropped that to 64.5 mpg. Not bad, but only good for a standing near the absolute bottom of the rankings among other journalists. Overall, the best score was 94.6 mpg, although that involved some less-than-real-world driving behaviors and conditions. The best "honest" score was 75.3 mpg. In all, about half of the journalists were able to get over 70 mpg, while the rest, save two, were able to get more than 66 mpg.



Increased fuel economy is one of many ways the 2010 Prius has evolved, but the driving experience is similar to the last generation. Despite a slightly longer wheelbase, wider track and new low-rolling resistance tires, you don't notice any serious changes from the driver's seat. The front MacPherson struts and improved body rigidity keep the ride smooth around town and on the highway. Overall, it's the same commuter-friendly conveyance you'd expect and, thankfully, rearward visibility is vastly improved over the outgoing model.



However, one small change we did notice was the absence of that infernal beeping when the car is shifted into Reverse that plagued the outgoing model. After asking Otsuka about the change, we were told that the pre-production models we were testing had the feature removed, but when the production model goes on sale, the beep will return. The good news? Otsuka said dealers can turn off the sound at the customer's request.

Speaking of current Prius owners, the automaker is convinced they'll trade up. In fact, Toyota's Bob Carter said the company expects 20-25 percent of third-generation Prius sales will be repeat buyers. So where will the other 75-80 percent come from? It's clear there's a hybrid sales fight brewing between Toyota and Honda, and Toyota needs to convince buyers that paying a few thousand dollars more for the Prius over the new Honda Insight is worth it.



The Insight, which starts at $20,470, is smaller and has fewer features than the Prius, but it's obviously a direct competitor. Based purely on aerodynamics, the Prius beats the Insight (0.25 versus 0.28 Cd). Honda was understandably proud of its "world-leading coefficient" number when the Insight was announced earlier this year, but Toyota has clearly bested its Japanese rival in this department. Does it matter? The Insight is a fun drive that won't attack your wallet at the pump or its point of purchase, while the Prius gets better mileage, is larger and comes with a cache of green cred that would fill the Grand Canyon.



Throw in the new 2010 Ford Fusion Hybrid, which is even larger and starts at $27,270, and 2009 is shaping up to be a good year for potential hybrid owners. With plug-in vehicles supposedly coming in 2010 (and pure electric vehicles not long after) and the poor economy, all bets are off on which hybrid will come out on top. Still, Toyota polled current Prius owners and 90% said their next car will be a Prius. The automaker wanted to offer these repeat buyers some upgraded technology, so it has included two new features on the 2010 Prius: Lane Keep Assist and Intelligent Parking Assist.

Lane Keep Assist (LKA) is triggered by pressing a steering wheel-mounted button that turns on the Lane Departure Warning system. The system looks for yellow and white lines on the pavement and lets the driver know if he or she starts to leave the lane. Lane Keep Assist is used in conjunction with the Prius' Dynamic Cruise Control, but it won't drive for you. The system knows if you let go of the wheel and using a turn signal will disengage LKA entirely.



Another fancy feature is Intelligent Parking Assist (IPA), which makes quick work of parallel parking. When pulling up to an available parking spot, you push a button above the driver's right knee to activate a sensor that can see where parked cars are sitting. When the system finishes its calculations, the rear-view camera turns on and displays a grid that estimates the intended parking position. If the grid is correct, the driver presses "OK" and then the system takes over. From this point, all the driver does is control the speed of the car using the brake pedal. If the driver takes his or her foot off of the brake pedal, IPA will shut down when it reaches its speed threshold. As smart as the new Prius is, however, it's not smart enough to know if a person suddenly appears in the designated parking spot. We were able to test IPA, and it works as advertised. Both LKA and IPA are available as part of the 2010 Prius' Advanced Technology Package (pricing TBD).

All new Prius owners will enjoy three new driving modes -- eco, power and EV -- along with a fourth when the other modes are off (you can read an in-depth description of each mode here). While Toyota cites an official EV mode (electric-only) top speed of 25 mph, we discovered that it's easy to get the gas engine, which now checks i at a larger 1.8 liters producing 94 hp, to kick in at a much lower speed if the battery has three or fewer bars. This information is available in the new multi-information display instead of the touch-screen on the current model. Volume and climate controls are redundant with a nifty new feature on the steering wheel called the Touch Tracer Display.



We noticed when cruising in EV mode, with plenty of juice in the battery, that when you go over 25 mph the EV mode does not re-engage when the car dips below the magic mark again. Otsuka didn't have an answer for why they designed the system like this, but it seems like Toyota intends EV mode to be used sparingly, likely to preserve the battery pack's longevity. Turn EV mode on when you're leaving your driveway and, when it clicks off, focus on Eco mode if you're into saving fuel. During the Beat-The-Chief drive, we engaged the EV button every chance we had, and while 65 mpg isn't bad, it does require constant attention to maintain.



In the end, Toyota knows most people drive a Prius because it makes saving fuel super simple. With the outgoing model, owners put up with abysmal rearward visibility because they got 45 mpg. They put up with the reverse beeping and the spaceship look because they can drive by gas stations without stopping more often. Now, with 50 mpg – or better – new Prius owners have even more reasons to quietly deal with any negatives the new car might have to offer. We have to wait until Toyota announces pricing to determine just how good a deal it is, but for the myriad of fuel-conscious consumers, the 2010 Prius could be their best option available.
