It will be interesting if it's not a 1.8l, though. What Toyotas currently use a 1.6l?

Corolla overseas and probably the new Yaris along with new 1.3 litre engines for both Corolla and Yaris overseas.

Let me update this - Yaris has 1.0, 1.3, 1.33 (soon) and 1.8 engines. Corolla 1.4 ZZ, 1.6 ZR, 1.8 ZR... New Avensis will probably get 1.8 ZR and 2.0 AR.

This article from Automotive news says it will be the 1.8L.

If they aren't going to Li ion batteries in 2010, the changes will be essentially cosmetic. The Gen II car is almost perfection--in its 4th or 5th year of production. I don't see how they can call the 2010 Gen III unless they change the battery system fundamentally.

As for 1.8L, I'm personally satisfied with the power of the present Prius. The Prius is not a car you feel you want to drive fast--it is so quiet and smooth, you just want to relax and enjoy the ride. You don't get that feeling in most cars.

Just because the "non-atkinson" displacement is increased does not mean that the engine is necessarily going to be heavier or even use the extra displacement for the intake stroke. It would allow for the power stroke to be effectively longer, so it could be even more efficient. It's easy to see how one engine parameter can be misunderstood. Just a thought.

if this new engine is the corollas 1.8 liter, it would be the ZR 4 cylinders that they are producing now, the major factor i believe would be dual VVT-i and the new "valvematic" system

this would mean the new prius would be a lot more powerful than the present one.

You are playing with catch words... who cares if it is lithium ion or nimh or whatever they use. We care about the results. If it is more efficient while being more powerful and having more space while it is about the same size, who cares what technology it has?

I could care less about lithium ion batteries if they are not ready.

To claim that such new technology cant be improved is just silly. Prius has been around for 10 years now which is baby steps compared to the petrol engines that have been around for century and yet there are always some new improvements.

mmm the 1.0 in the 2010 priuswith a turbo and supercharger of-course just in the case you need some more power that a normal 1.0 on a prius can not
and the rest of the time.... 1.0 mmmm LOW fuel use on the highway

you do understand that at highway speeds, that 1.0 turbo would be boosting all the way? :-). 1.0 Yaris spends more fuel at 90 mph than my Lexus GS350 AWD. It is highly efficient in the city and country roads, of course.

Thats the problem with turbo engines - they are fine when nothing is happening but spend more fuel otherwise.

Autobild (biggest german mag) had feature recently where they tested 20 different cars in the city, 3km driving. They had Rav4 Petrol (2.0 AZ engine, old, old) that got 12l/100km while 1.4 Twin Turbo Tiguan (which on paper has 30% better mpg got 14l/100km. Worst offender was 330 turbo that spent 20l/100km. They didnt drive the cars fast, just normal city driving.

Even a slightly larger engine will make a big difference on long hills, which is where I notice the current powerplant's shortcomings the most. A turbo would be wonderful to compensate for thinner air at higher altitudes, but it's probably too expensive and complicated for production.
