New generation 4 cylinder for future Hybrid?

Hi C....,

I am not interested in buying a Highlander, but its disappointing they are not going to offer the Highlander Hybrid with this new engine.

 

I second that. I would be very interested to see the MPG of the Camry with the new 2.7 and HSD together.

 

I agree. I think that the 2.5L atkinsonized plus HSD would be a great coupling for the TCH and for the Venza hybrid eventually.

Take the Venza as an example.
It will have ~189 hp from the basic 2.7L 1AR
It will have 268 hp from the upgrade 3.5L 2GR
.
.
It could have ~220 hp from a 2.5L 2AR + HSD but much better FE numbers.

This would be akin to the very clever situation of the Camry and TCH today.

 

it could use some direct injection, so i'm not impressed, they should have optimizing valve timing with the exhaust and the intake in the first place and not implement one after another in newer models.

 

What is there to be impressed about?
Honda's 10-year-old engine series of SOHC can achieve
190hp/162ft-lb with 2354cc. By projection, it can make
217hp/183ft-lb at 2700cc.
That is 30hp more than Toyota's.

I agree with the previous post.
If I see direction injection like those of Audi FSI, I will be impressed.
Wait till Honda release its new series of engine with A-VTEC with direct injection.
Ford/Mazda is also working on direct injection engines to be release before 2012.
I am sure Toyota is also working on that also.
5-10% efficiency gain waiting to be had.

 

The latest Opels make 180hp with a 2.2L DI engine.. Toyota is seriously behind the curve here.

 

those old accord power figures are under old hp rules, and old emissions... todays engines have stricter cats as well which restrict hp and mpg as well.

New 1.6 and 1.8 ZR series engines are class leading mpg and refinement, confirmed in real world tests.

Toyota had direct injection engines on sale in 1999 .

 

heh, shows how much I know about Honda... he said 10 years so I thought it was old.

Maximum numbers mean very little - 2ZZ-GE had 192hp in europe so what? Definetly not an engine to put in an SUV .

Wonderful engine though, got awesome mpg for what it was, although at the end, it was suited only to light cars.

 

its 190hp at 7000 rpm and 162lbs/tq at 4400 .

And guess what - 170hp 5AT version has lower mpg than AZ engine in Camry, which this new AR series engine should beat by close to 10%

 

i am getting old... in any case, let me repeat it here, as it is more relavant... earlier this year, we had dealer conference in london, for all toyota dealers... bunch of upcoming models were shown and there was talk about technology as well.

my post from other forums on that time

Compared to new R series, move from double VVTI to Valvematic will bring around 8% gain in economy and performance at the same time.

---

I completly forgot about that . New Valvematic engines will start to be introduced (in Europe) at start of 2009 with new iQ and then refresh Yaris.

 

Also, all engines will be getting valvematic by the end of 2010...

 

- valvematic replaces dual vvti
- as to the redline, due to how Lift works, power delivery in that Honda is no linear - meaning at 3000 rpm, AZ engine should have more torque. That was always the issue with VVTL-i as well, until 4,000 RPM, it behaved a lot differently - as an engine that has a lot less hp - which I personally did not mind as it had stellar fuel economy (I had Corolla TS which had 2ZZ-GE VVTL-i).
- Toyota redesigned 2ZZ-GE in US market to make less power but more torque (2004? 2005?), thats why it was 164hp at the end (it was 17x before those new ratings, 180hp with original engine).

So all VVTi engines will be replaced with Valvematic - that was promised until 2010 by Toyota European boss.

Compared to old ZZ/NZ/AZ series, it should be 15% improvement (R block + valvematic together) which is huge improvement for petrol engines...

 

p.s. Smart does not have great fuel economy for car of its size - Aygo already beats it with 1.0 engine, and iQ will have around 10% less consumption than Aygo.

 

It should replace it by 2010... Word from Toyota euro execs.
I would guess that they did not have time to implement it and didnt want to delay new R series engines for it... In any case, they said it would be on every petrol engine. It makes sense if it is significantly better in both power and mpg, while not being more expensive.

Auris 1.6 is not CVT - it is MMT, like DSG just with single clutch... Its ok - it gets mileage of manual, with half of the cost of automatic transmission. You still have to think a bit to make it work the best, but if you do, it works well. It has paddle shifters to change gears as well. Looks pretty cool. Latest version in Auris is the best implementation yet. They also have them for diesel engine (1.4 D4D).
