Last night, I was thinking why Toyota can't put a 2.0L instead of the 2ZR-FE engine for the new Rolla since Toyota already extended its launch by one whole year. I think everyone here thinks it would probably be the 1.8L 2ZR-FE, but in North America I don't think Toyota "just" want to be competitive with the likes of Honda (Civic) with it's base 1.8L, which is about on par with the 2ZR-FE. But to exceed them like last gens 1.8 vs 1.7. So I thought? Maybe Toyota does have something up their sleeves; maybe a 3rd generation ZR-FE engine? The next logical thing to do was to do a Google search for a 3ZR-FE. Many of the searches that popped up was irrelevant, but one was particularly intriguing was from this Japanese site:
After translating, at the bottom it says the full model change for the Noah:

2007 full model change
Full model change is planned in May of 07. New model Noah so far sort [hurendorii] which is conscious of family use adopts the styling. The interior Toyota to seem material feeling is high, width of practicality and the interior in addition as a mini- van improves to class top-level, the rival follows. As for becoming the eyeball with mechanism, as for on-board engine setting new development 3ZR-FE type 2.0L direct 4 to main. This engine being new model Corolla already, in enlargement edition of the 2ZR type which debuts, adopts dual VVT-i. In addition to this, it sets also the 3ZR-FAE type engine which adopts the stepless variable valve timing mechanism which is called the P system anew. Both mission adopts CVT. But power efficiency and improvement of fuel economy of course with the new engine, you call the especially P system car that nearly former compared to 20% fuel economy raises. The grade, “YY” of 5 passengers, “X” of 8 passengers and upper-class grade “G”, becomes 3 number width with [supotei] depending upon wide fender adoption, it designates 3 grades “of S” as the basis, respectively setting FF and 2WD. In addition completeness equipment “the L package” of convenient price is set to volume sales grade “X” distantly. In addition, it sets also the rhinoceros drift-up seat equipped car to “X” and “S”. Furthermore, as for the engine “S” of “YY” of FF and FF and 4WD 3ZR-FAE type, other than that becomes 3ZR-FE type. White pearl crystal Shine, silver metallic, gray metallic and black, dark lead mica metallic and the dark blue mica, planning the body color of setting schedule light/write blue mica metallic 7 colors. Price is held down to like existence.
What's even more interesting is it also talks about the "P system" Toyota's version of Honda's A-VTEC or stepless variable valve timing system.
Conspiracy theory, I don't know, but it sure gets your heart pounding!!!
Well the 1ZZ has been around since 1998. I have no idea why Honda went from 1.6 to 1.7 in 2001 when they could jumped to 1.8 litres if they wanted to. I guess they just wanted to match the Corolla in fuel efficiency (which is pretty much identical in Canada) but unfortunately it lacked in numbers (115hp and 110lb-ft). Now with a more powerful 1.8 litre, the Civic feels much livelier and definitely how it should've felt in the first place. Oh and don't be fooled by the 155hp version in the Acura CSX. The extra power is pretty much offset by the extra weight. I've tested both a Civic EX and CSX Premium and they both feel roughly the same in terms of acceleration. I was expecting the CSX to give a bit more of a speed sensation when punching the throttle but it didn't. Either way, they're fairly comfortable and fun-to-drive. Anyway, enough about the Civic, on to the Corolla! It would be nice if they did drop a 2.0 litre. However if they put the 2ZR 1.8 litre and dropped all the goodies (e.g. dual VVT-i and direct injection), I'd gladly give up the 2.0 litre for a high tech 1.8 litre. It'll make more power, be more efficient and be slightly lighter. Dual VVT-i is unheard of in this category if I'm not mistaken so it'll be nice to see Toyota trickle down the technology to its inexpensive cars.

No, I mean Toyota will make a 3rd generation ZR-FE engine which will be a 2.0L with all the goodies you said like dual vvti. In the article it says there will be an even more advance ZR engine called 3ZR-F"A"E, where it goes a step further with "stepless" dual vvti, which is like Honda's new A-VTEC, where the valves are optimized at all engine speeds.
Toyota recently filed for patents on something called "Valve Matic". This could actually be the marketing term for the "P" system.
The 2ZR-FE already has class-leading fuel economy, so this rumoured 3ZR-FAE sounds very interesting.
I believe Toyota has more in store in terms of engine innovations than even what they have now (Dual VVT-iE, D4-S). There is also some insider information that the IS-F's engine code is 2UR-GSE. This means the return of G heads, likely a new generation of G heads.

Ohhhh.... "excellent"
In that case, put it in the Corolla!! (and the Prius )

I thought the current VVT-i and Dual VVT-i systems are stepless?
Regular vvt-i doesn't have lift. With stepless, you can have a seamless "lift" at any rpm you want not like VVTL-i where you can only have lift at higher rpms and also you get valve variations in vvt-i for fuel economy. It's more like a mix of all the vvt technologies into one, but more efficient.

That is incorrect. VVT-i in any form deals ONLY with variable cam phasing. There is no variable exhaust and intake cam lift (through multiple cam switch overs) in Dual VVT-i or VVT-i regardless of rpm.
To clear difference among each, this is the simplest definition of each:
VVT-i has variable valve timing only on intake valves (accomplished through constant cam phasing).
Dual VVT-i has variable valve timing on both intake and exhaust valves (accomplished through constant cam phasing of both intake/exhaust).
VVTL-i has variable valve timing only on intake valves + variable cam lift on both intake and exhaust cams.

That's what I said, I said vvt-i doesn't have lift. The seamless part is of a new tech that Toyota is calling maybe "Valve Matic" to go against Honda's new A-vtec where all kinds of valve durations can occur (including Lift) at any particuler rpm.

Very interesting, indeed. It must be a Formula 1 derived technology. The trickle-down effect is working finally.

what's variable cam?
