CD Article: 2009 Toyota Corolla

Dual Variable Valve Timing with intelligence (VVT-i) on both the intake and exhaust camshafts that helps it achieve "outstanding performance and economy" is the major change for the 2009 1.8

2008 Corolla 1.8 specs

10.0:1
Horsepower hp (kW) 126 (94) @ 6,000 rpm
Torque lb.ft. (N.m.) 122 (166) @ 4,200 rpm
 
2009 Corolla 1.8 specs

10.0.1
132 hp at 6,000 rpm
128 lb.-ft. of torque at 4,400 rpm.

However, this is the definition of a new Toyota 4 banger.  Essentially going the same route like BMW's valvetronic.

 Tokyo, Japan - Toyota Motor Corporation has announced its development of Valvematic, a variable valve lift mechanism that combines the company's VVT-i (Variable Valve Timing-intelligent) with a new mechanism that continuously controls the intake valve lift volume.

By adjusting the volume of air taken in by intake valve lift, Valvematic ensures optimal performance based on the engine's operational condition, and achieves both high fuel efficiency and performance. In the case of a new 2.0-litre engine developed by the company, Valvematic improves fuel efficiency by 5 to 10 per cent, reduces CO2 emissions, boosts output by at least 10 per cent, and enhances acceleration responsiveness.

The company says it plans to introduce Valvematic shortly, starting with a new vehicle model featuring a 2.0-litre engine. Toyota also says it plans to completely revamp its gasoline engine and transmission line-up by 2010.


Valvematic, an evolution of the VVT-i mechanism which now incorporates continuous valve lift control together with VVT-i’s existing valve timing control. Valvematic also eliminates the need for a throttle valve, instead controlling the volume of intake air using valve lift instead.

Heard the toyota ad on the radio this morning.

MSRP is down to "equal the previous discounts offered"

Some of you need to get your facts straight. The 1.8L IS an all-new engine. Just look at the engine codes. The old 1.8L was a ZZ engine, this is a ZR engine. This signifies a new engine block design. Just because it has the same displacement as the old engine doesn't mean it's not new. The new ZR engine is also NOT the same size and mass as the old ZZ engine. The ZR 1.8L is smaller and lighter than the old 1.8L ZZ. The new ZR engine is 17mm shorter than the old ZZ 1.8L engine. This new ZR engine also uses roller rocker arms combined with piston oil jets and ultra-light pistons. The old 1.8L ZZ never used piston oil jets. And of course it has Dual VVT-i, compared to the single VVT-i system the ZZ engine used. The water pump, lubrication oil routes, and chain case are all modularized for a more compact engine package.

And no, the new ZR 1.8L does not yet use Valvematic.

What I gather from this post is that the 1.8L Toyota engine is a new and therefore its reliability is UNKNOWN.

ZZ that would make it.......................wait ferrit    TOPS man i could so wear that ta WORK

My wife thinks the new Corolla tv is very good, it gives a lot of info in a short period of time

The four-cylinder powerplant in the CE, LE and S models has a displacement of 1.8 litres as in 2008, but it's an all-new version that increases horsepower from the previous 126 to 132, and with a step up in torque from 122 lb-ft to 128

It's not an all new engine.  It's a new version of the 1.8.  It's more complicated with the Dual VVT, so technically one could agrue that it has more parts that may screw up.  But almost all the companies have transition to dual VVT on their motors with no negative consequences.  Therefore, there will be no change in reliability.

When the Toyota "Valvematic" motors arrive then you can consider them all new because they will be designed from scratch.

I think it's naiive to think that this engine will not be as reliable as past Toyota engines.

It appears 2zr engine has been produced since summer 2007. If there were issues with it, it would have been postponed for NA.

And where is our Fielder?

I thought the Corolla was postponed for about 18 months or so.

[EV Dan]

  it could have been the period needed to throw in the new ZR but who knows.. It is a new engine even for Japan (2007)

I think it's naiive to think that this engine will not be as reliable as past Toyota engines.

So we should presume that it is just as likely to sludge up as past Toyoda engines? 

[safristi]

Mmmm FUDGE............ that nice matrix centre

My dad drives a 2000 Corolla with 1.8 litre VVT engine, and he never experienced any sludge.

From what I gather, none of the Corollas suffered from it, and just one mistake shouldn't taint Toyota's reliability.  Talk about recent years.  Don't go back 7+ years!

[safristi]

aged Fudge is tha bestest..............keep yer knickers on man.....   how's aboot a 3 round SLUDGEFEST......

[Greg B.]

Talk about recent years.  Don't go back 7+ years!

I have no difficulty doing that, as long as the bashers of North American makes agree to do the same and stop talking about the problems of their '81 Citation as indicative of today's models.

[EV Dan]

Is there an engine that doesn't sludge? Maybe one that doesnt work in the first place - see, no bashing  Drive in city traffic use cheap oil and change it once a year every 7.5 and you've got it. It's all turn-the-key-and-go people. Sludge is in the heads.

[Arctic_White]

Fair enough.

[safristi]

rented a 80's Citation outta Vegas years ago the seat frame woz lose so it was fun in the desert at 100MPH.................can't wait to re_LIVE the Grand CANYON..with my fillings in place this time....

My wife thinks the new Corolla tv is very good, it gives a lot of info in a short period of time

To the tune of "Mambo No. 5" and in keeping with the new ad:

With a little music, song and dance,
And a little SFX per chance.
They give a lot of info on TV
To get some buyers like you and me.

The Corolla will sell big
Even if it becomes a pig.
With all those new features in play
I hope they haven't lost their way.
