Toyota going to turbos

Toyota has big plans for its model lineup, as the automaker intends to introduce 11 new or redesigned vehicles by 2012. This will be accomplished by offering hybrid versions of existing models, as well as introducing all-new hybrid vehicles. However, Toyota's focus isn't going to be entirely on improving the electric half of the hybrid equation. The automaker is looking at ways to produce more efficient gasoline engines, and turbochargers and direct fuel injection are both in the cards.

There's no word yet on which models will benefit from either technology first, but the initial round of products should also come equipped with start-stop technology in addition to the DI and turbo. It was hard to believe at the time, but maybe a turbocharged, hybrid MR2 really is right around the corner.

I really would not want a turbo hybrid. Few things can be worse than shutting down a turbo after accelerating.

All he rest, great. But I hope they do not make a turbo hybrid model without a LOT of proof of 250k longevity.
 
All I know is on my older RAV 4, when I slam the pedal, I never have to worry about snapping my head clean off.
 
Turbos suck no they blow .I would rather not have them on my cars. Even though my wifes Ford Truck has one ,I would rather not wait the EGTs drop to safe before shutting off the engine.
 
I was looking at Fords for my next car so I can get into the affordable turbos and the DIs. I'm glad Toyota is planning to offer the same options.

IMO it is really no big deal for most use. I have a turbodiesel and two turbo gassers. Im not very concerned so long as they get driven/idled lightly for a little bit after being used hard or under high flow like on the higway.

But hybrid service has no guarantees of if/when the engine will turn off for economy. Different operational profile, unless there is an EGT meter that is part of the logic, adding $$$.
 
Subaru has for years developed a cooling system that thermo syphones coolent to the turbo as the engine/turbo as the engine is off and cooling down. Properly designed, I see no reason to avoid turbo charged engines. Good turb/engine designed are not the old days when turbos were not water cooled.
 
Okay had to remove and issue warnings for some members trolling in this thread.

Back on topic, I'm going to stay away from DI and turbos as long as I possibly can. Hopefully I'll keep older vehicles with out these "features" going for a long time.

Not impressed. Plus putting so many new vehicles out at the same time is going to do one thing for their rep. Hurt it further no matter the manufacture.

To have adequate volumetric efficiency they'd have to be around 1-1.2 liters in a prius sized car. To me that says 3 cylinders.

They can cool down charging the battery, no biggie there.

I just have to wonder with Buick, Hyundai, Chevy, Toyota suddenly building all these turbos if there's a weak link in the supply chain somewhere... bearings, I don't know... but some supplier factory that's suddenly working three shifts and quality suffering somehow. Don't get me wrong, I'm thrilled for some attention being paid to making *efficient* cars.

Once the battery loses power, Prius's (2nd generation at least) are underpowered. I recall distinctly going up in VT people flying by my WRX in a Prius but then slowing down in long grades as the battery is depleted. Turbo may alleviate this problem, it sure does on my WRX with a 2.0L.
 
Turbos are good in that they allow a much smaller displacement engine to make the power of a much larger engine, and in turn, the smaller engine offers much better fuel economy when not being run hard. The down side is nobody seems to be able to make a turbo that will last.

You ever seen a turbo anything last 200-300K miles or more? I never have.
 
My 1.8t went 170K with dead stock tuning ,once the revised coil packs were installed . The water pump b0-rK ed at 57Kmi.,so the timing belt and tensioner wouund into the head and were replaced .
once the cam spun reliably it was the long stroke wATERPUNMPER THAT KEPT ITS BORES TRUE AND MADE POWER WITH THE STEADY THRUMTHAT COOLING FANS DID NOT INTERFERE WITH .

It's not nearly as common to see turbos lasting 200-300K as it is naturally aspirated engines, and until they get to that point (if they ever do), a lot of people will be aprehensive about buying a turbo....
