2010 Toyota Prius

Toyota’s third-generation petrol-electric Prius hybrid is expected to make its world debut at the Detroit Autoshow in January next year before going on sale in Japan and the U.S. in April. The changes planned for the new model will be minimal, as these latest spy images of a near-production-ready prototype reveal.

This one´s for Tideland, drooooool buddy! :D

1.6L hmm... interesting... I see 4 wheel disc brakes! =)

I was led to believe Toyota will incorporate a 1.8ltr engine. I don't think Toyota has currently a 1.6ltr unless they are making a whole new engine. We'll see.

That's what I remember reading also, that Toyota would put a 1.8-litre engine (likely the Corolla's 2ZR engine?) in the new Prius.

I don't think Toyota has currently a 1.6ltr unless they are making a whole new engine. We'll see.

Toyota does have a 1.6-litre engine, the 1ZR, the sister engine to the North American Corolla's 2ZR 1.8-litre engine, and used in Corollas elsewhere.

Regardless of which gasoline engine goes in the next Prius, I wonder if it will have Valvematic?

We will know soon enough.

Can you see if it retains the Tokyo-by-night instruments and the stubby gearshift, or has it switched to conventional round gauge instruments and a conventional lever? :D

LOL..

SULU... build me the Corolla with HSD. ;)

Thanks for the clarification. See being in the U.S. I assume there's nothing else out there beyond our borders. :lol::lol::lol::thumbsup:

Toyota’s third-generation petrol-electric Prius hybrid is expected to make its world debut

Welcome to 2004?

Welcome to 2004?

No.

The Gen1 Prius was introduced in Japan in 1997. It received a mid-cycle refresh and was exported to the Rest of the World, including North America, for 2001. So the Prius we got 7 years ago was Gen1.5.

The Gen2 Prius arrived in 2004. This is the fastback/hatchback Prius that we now have.

The Gen3 Prius that is the topic of this thread arrives in 2009 as an early 2010 model.

LOL..

SULU... build me the Corolla with HSD. ;)

:thumbsup: Yeah! Build me one!

Thanks for the clarification. See being in the U.S. I assume there's nothing else out there beyond our borders. :lol::lol::lol::thumbsup:


There's this big piece of snow to the north of you that is the buffer between you and the Rest of the World. Nothing else matters. ;)

^^Cool! Thanks!:lol::thumbsup:

I'm guessing that this 3rd gen will be an evolution in exterior design rather radical. I'm guessing it will still have the same overall shape cause of the nature of the vehicle. I'm sure Toyota will add more goodies as its their halo hybrid car.

I'm guessing that the shape of the Prius has become part of its brand identity, its trademark. People instantly recognize the shape as a Prius, and Toyota may lose sales if they gave it a more conventional, 3-box shape, because they would not recognize it as a Prius. This is similar to how all BMWs have that twin-kidney grill and the Hofmeister kink in the rear-most side window; both are identified as BMW trademarks.

This is probably why the new Honduh (I like that, can I use it occasionally? :D) hybrid vehicle looks like a Prius. I wonder if Toyota could charge Honda with trademark infringement?

also read in motortrend...

2010 prius pre-show model pics is leaked complete with driver and moving shots- no computer rendering. it's definitely the same jelly bean we're all used to. it retains its height, but length and width grows very, very little (no numbers). plug-in model is not going to debut at the same time, but is somewhat confirmed for production down the road. the article doesn't mention it, but it seems like hid projectors are implemented, as well as front amber-when-lit led turn signals. fenders buldge out a little, hinting at a little "sportiness" (ha!). nonetheless, it's not as flat-sided as the current offering. wheel and tire package is definitely low-profile, seems to be around 17" (but it's not production, so those are 50/50). rear shot isn't given, but from the 3/4 angle, it seems to retain a very similar rear end as the current generation. 4-wheel disc brakes are somewhat obvious. grille-emblem placement is similar to the camry/corolla/yaris.

i'd go to your nearest store and look it up for yourself. the paint of the prius isn't too shabby and seems to fit the prius (it looks close to the flamboyant "speedway blue").

I was led to believe Toyota will incorporate a 1.8ltr engine. I don't think Toyota has currently a 1.6ltr unless they are making a whole new engine. We'll see.

I too had heard that but I think that the 1ZR is the 1.6L. Wiki link here http://en.wikipedia.org/wiki/Toyota_ZR_engine

Maybe they did hear the input from current owners that the current model is plenty fast enough. More fuel economy!...More fuel economy!!...More fuel economy!!!

They do know how to keep the pot bubbling though..good marketing.

The three models ( two generations ) of the Prius are
NHW10 - Gen 1
NHW11
NHW20 - Gen 2, our current model
NHW30 will presumably be the Gen 3.

Yep. For the last 3 months Toyo has been leaking bits and pieces of info/data to well-regarded sources. The initial data set was leake to Edmunds among others with these tantalizing tidbits.

Same shape and configuration as a 5 door hatch
3" longer
3" wider
Somewhat heavier but not too much
A larger ICE, 1.8L or 1.6L Dual VVT-i, but no mention of Valvematic or not.
Same NiMH battery technology - for the time being
Due 'line off' in April 2009 for arrival here in summer 09 as a 2010 model
Small solar panel in the roof to assist the HVAC
But...
160 hp combined iso 110 hp as in the Gen2
10-20% better Fuel Economy than the Gen2
And...
some new and better Prius-toys......soon to be incorporated in the rest of the lineup.

Thanks! I wonder if this engine will eventually replace the 1NZ engine (in the Yaris) that is a great engine but aging. Obviously Toyota will incorporate Dual VVT-i and then Valvematic to their line up or assuming so to keep up with emissions regulations and competition. Or maybe they'll use it in a cheap sporty or sports car. That would be nice. But probably not. What was thinking:headbang::lol::headbang::lol:

No. Toyota has announced the new NR engine family with the new STOP-START system to replace the NZ engine family. With this new idle-stop system, I am assuming that the small engines (smaller than 1.5-litre size) will no long be available with HSD.

See the following quote from the RAV4 thread:
Yes, it does seem that the 2.5L 2AR-FE makes 179-180HP. This means no Valvematic. With Valvematic, this engine would have been making roughly 198-200HP. Looking at the numbers now for the 2AR, the 2.7L 1AR in the Venza will make roughly 193HP and 186 lb-ft (assuming no Valvematic, mechanically same as 2AR). The only question is whether or not the 1AR will have Valvematic. With Valvematic, it would make roughly 214HP.

Also, based on converting the Canadian fuel economy numbers for the 2AR, the EPA estimates for the 2009 Rav4 with the 2.5L 2AR should roughly be this:

2WD: 22/29 EPA (compared to 21/27 EPA for 08 Rav 4 2WD 4 cyl, an improvement of roughly 4%)
4WD: 21/27 EPA (compared to 20/25 EPA for 08 Rav 4 4WD 4 cyl, an improvement of roughly 7%)

This would indisputedly make the Rav 4 with the 2.5L best-in-class in terms of fuel economy. So the engine brings BOTH increased power, as well as increased economy. I will also bet the 2AR is cheaper to manufacture, more reliable, and more refined than the average 2AZ it is replacing.

This is almost guaranteed to be the same engine that will be in the 2010 Camry replacing the 2AZ as well. The Camry could see even bigger fuel economy gains with the 2.5L than the Rav as the Camry has less frontal area, and therefore less drag to deal with. I estimate the 2010 Camry 4 cyl will achieve 22/34 EPA (assuming a 4 speed auto). If the 6 speed/2.5L combo is true, then the Camry 4 cyl could possibly achieve 24/35 EPA. . This also means the 2010 Camry 4 cyl will have considerably more torque than the 4 cyl Accord, not to mention be more fuel efficient and very likely more refined.

Last but not least, I have managed to find some pics of the 2AR-FE, the 1NR-FE (the new 1.3L engine) and also the long-awaited new compact 6 speed manual for FWD applications.

2AR-FE:
http://techon.nikkeibp.co.jp/english/NEWS_EN/20080612/153224/5A.jpg

The 3-stage variable oil pump sounds interesting, especially how it will benefit the engine when it's pushed hard. The intake manifold looks like a much better design than what the 2AZ has.

1NR-FE (with stop-start functionality):
http://techon.nikkeibp.co.jp/english/NEWS_EN/20080612/153224/5B.jpg

Estimates from Toyota insiders are saying the 1NR-FE will make roughly 99-100HP. Fuel economy will surely be class-leading among small (less than 1.5L) 4 cyl gas engines.

6 Speed Manual for FWD cars:
http://techon.nikkeibp.co.jp/english/NEWS_EN/20080612/153224/5C.jpg

A very compact-looking unit. Hopefully this will see widespread use among Toyota's model lineup in the US, and not just overseas.

It's almost guaranteed this manual will see widespread use among 4 cyl models, and the only question is if it will be mated to 6 cyl models. Those wanting to see a manual Camry V6 SE, there is still hope.

EDIT: it appears final numbers for the 2AR may be 180HP/173 lb-ft, not 179/172. Venza 2.7L estimated numbers should be roughly 194HP/187 lb-ft.

Also after some digging around, it appears the transmission choices for the 4 cyl models will remain unchanged. So the new 2AR will make do with the old transmissions on the Rav 4. It may be disappointing to some, but I think the new engine will match up better with the transmissions. Also it's impressive that the new engine will achieve such fuel economy figures with only a 4 speed tranny (if true).

^^^Thanks Sulu man this is getting confusing:lol::lol::lol:

So does that mean the Yaris will get a small Start-stop engine or have the same engine size but different family with the start-stop technology? I remember reading about the new start-stop ones but wasn't sure if Toyota will apply that to NA engines or NA bound engines.

the yaris will have a small start stop engine
dual vvti if im not mistaken
and when its finalised and more or less bug free
valvematic with start stop and dual vvti
when that day comes the yaris is going to have 50mpg or something lol

^ if above is true... I'll wait for that model Yaris! =)

with technology being adapted to other models

those small 1.4l engines usually making 90-100 hp with valvematic can reach much higher HP and torque
and will be getting more and more fuel efficient :chug:

So the day will come when all toyos will come with dual VVT-I & Valvematic.
When that day comes Angels will sing in an Immaculate Chorus or maybe we can have beer and cake :clap:

I hope so for the 2011 tacoma. I want the tacoma to have better fuel economy (the V6 at least) that will be :thumbsup:

hum?
interesting there
lift was developed to squeeze every bit of power from small engines
its how a small 1.8l engine naturally aspirated was able to get a 100 per L ration very hard thing to acomplish for any engine.

I wonder what that technology will do in a 6 cylinder o_O
will toyo be using smaller displacements pumping out same power and torque
or will they increase the displacement add the tech and boast outstanding millage on such powerfull engine.

Hum. You have made me curius.

If you are referring to the Honda S2000, the great horsepower -- more than the magical 100hp/litre barrier -- was at the expense of daily driveability. Its engine was designed to spin very, very fast, which gave it great horsepower at high rpm, but also gave it a terribly low torque figure, that peaked at very high rpm, making it a real pig to drive daily in city traffic. There is just not enough space, or time between stoplights to get the engine spinning so high.

Honda admitted this when they swapped in a larger engine, with greater torque available at lower rpms.

You definitely do not want that in a truck engine. You do not want high horsepower at the expense of low torque; you prefer, in fact, high torque, if at the expense of lower horsepower, which is why diesel engines do so well in trucks. In a truck, you need torque NOW to pull those loads that may be in the pickup bed or in the trailer being pulled behind. That is not to say that technology such as variable valve timing and lift should not be used in truck engines to increase torque and power, without increasing fuel consumption. Perhaps one reason the Honda Ridgeline does not sell is because they put a Honda car engine in it, and Honda car engines are known to be high horsepower, low torque tradeoffs.

Ahh. Finally some pictures of the new iQ drivetrain. That 1.3 with Stop and Start will surely be the big petrol engine and that 6 speed should fit in if the pictures aren't wrong.

Great find.

well i was saying thats what it was initially developed for
pumping out 40 more hp out of the 1zz

but valvematic pulls extra hp out of all rpm ranges so im sure it will be able to deliver at all rpms not just the upper

well i was saying thats what it was initially developed for

The 2ZZ engine did offer 40 more hp than the 1ZZ engine, but that was not just VVTL-i that made that possible. Comparing the two engines, although the displacement is roughly the same, the two engines are different because the designs of the two engines was different.

In the 1ZZ engine, the ratio of the bore (the width of the cylinder) to the stroke (the distance that the piston travels between bottom dead centre (BDC) and top dead centre (TDC)) is less than 1 (meaning the stroke is greater than the bore), but in the 2ZZ engine the bore to stroke ratio is almost equal to 1 (meaning the stroke and the bore are about equal). A longer stroke engine provides greater torque at lower rpm than a shorter stroke engine (a factor of the longer crankshaft). The shorter stroke engine can, however, spin at higher rpm, providing greater hp (engine rpm is a factor in the calculation of engine hp).

The diesel engine and truck engines have a longer stroke, providing great torque, low in the rpm range, but the engine cannot spin at great speed because the greater up-down distance that the heavy piston travels prevents this; so the greater torque is at the expense of hp. Race engines, Honda engines and Ferrari engines have a shorter stroke, which allows the engine spin to high rpm, so they provide high hp at high rpm, but at the expense of torque.

Variable valve timing and variable valve lift and duration do help the engine to breathe better at all rpm ranges. Before variable valve timing and lift, engines were tuned to offer the best breathing at higher rpm ranges, so maximum possible torque and hp (and hp is calculated from torque -- so torque is measured, then hp is calculated from the torque and the engine rpm) was not available at lower rpm ranges. So, yes, you are correct that variable valve timing and lift will improve torque, but only to the point that the design of the engine allows, and the design of the Toyota 2ZZ and the Honda F20C engines were designed with shorter strokes, preventing this.

Valvematic, with continuous, stepless variable valve lift and duration will help provide maximum possible torque and hp at all rpm, but again, only as much as the physics of the engine design allows. And, in a engine that has a bore to stroke ratio of greater than 1 (short stroke), the physics does not allow for great torque at low rpm (unless you have a larger engine, but then you consume more fuel).

Well following the same logic
If it goes as ive come to understad it.
If with a 3.2 l v6 mid truck / small suv
you get 260 hp with 220 ft/lb torque i supose
with valvematic should be getting a spread of more hp and torque throught the rpms
even if its not a large peak power icrease
with the stepless system it should deliver power evenly throught all rpms
if it is built correctly.


is it me or do i think toyota might implement a cvt tranny and valvematic in lexus models soon
power without the jerky motion of switching gears seems like it might be what they going after?
or am i just reading to many rumors and speculation articles @_@

iiT LOOKS SMALLER FOR SOME REASON[...] MAYBE iiTSz ME[??]
