Hybrid: Longevity of Turbo Engine

1714 Views 17 Replies 9 Participants Last post by  Kianadian92
So I'm deciding between a Rav4 hybrid and Sportage. Well, more accurately I'm waiting for both and will probably buy the one that I can get at msrp first. But I digress.

I saw a review today that said that the Kia uses a turbo engine, which could lead to more problems since it tends to operate at higher temps and under more pressure (the rav4 is "naturally aspirated" which sounds delightful). Is this right? How much of a problem is this? I typically keep my cars for 12 to 15 years and about 120k miles. Thanks.

If I recall correctly, the 1.6T engine runs with less compression than most NA engines. As far as longevity goes, I've seen same engines run for many many miles without an issue ... or they fail before the first oil change.
As long as the vehicle receives proper maintenance at regular intervals, 120K probably won't be a problem

Something to keep in mind.....GDI engines in general require more maintenance every 30-60k because of the carbon build up on the valves. It's equally important to use a high quality oil.

Mine started rapping like a diesel about a month after purchase. Dealer is supposed to check it again on the 27th. It can really only be heard from the passenger's side, which I forgot to tell them at first check. I'm in the process of working on a deal to trade it in, so we'll see if I still have it for that appointment. I'm at 6,500 miles, a transmission replacement, that's acting up again already, this engine noise, and it isn't vey good in the snow (probably the tires). It's turned out to be less than I hoped for, so I think it's time for it to go, if I'm able to. If not, I'll end up pushing for Lemon Law, then get something else. I'm currently working a deal on a new Outlander. Real fuel economy not much different than I'm actually getting with the Sportage Hybrid. I'll keep everyone updated.

Hi, not sure if related to anything or matters in any ways but was yours made in the US or Korea kia factory. Sorry you are having a tough time.

All hybrids are built in Korea, so far.

Sorry dude, this is good info. I'm more comfortable with the naturally aspirated I think. The more I learn the more I lean this way.

RAV4 hybrids are impossible to get, but I guess I'll just get on a few lists. If it doesn't work out, maybe I'll go with the non-hybrid sportage. Thanks for letting me know about your issues.

Well yeah, if you consider the component quality to be similar, simpler is always going to be less prone to malfunction.
The turbo vs. NA debate has been back and forth and the specifics of the engine is probably going to make more of a difference since turbocharged engines are designed for the increased forces from the start. Theta II in both NA and turbo guise is subpar either way, the EcoBoost has been around a while and the different engines under that brand have had varying reputations.

Of course there's the whole "having less parts to fail" benefit of NA engines which I'd say is a plus but it's also worth considering the rest of the vehicle since transmission choices can vary, etc.

In addition, turbo's have been reliable on many diesel engines for ages.

The turbo's on domestic commuter vehicles is a relatively new thing, and apprehension is understandable.

We always related a turbo to be for the track and boy racers, but in our application it brings significant efficiency gains.

Diesel engines have much stronger cylinder walls and engine blocks though.
I really don't think the turbo will help with the efficiency in real life driving though. EPA MPG testing, probably, but not when real people drive in real life settings. But then, I've never had a turbo engined vehicles, so don't take my word for it

What ron1004 means is that turbodiesels are common and their turbochargers aren’t blowing up on the regular so turbos can certainly last, but it’ll probably come down to the specifics of a given application like how I remember hearing some blurb about turbo Subaru's (back in the day) allegedly being more resistant to headgasket issues.

From what I can tell, turbos can yield better efficiency under light load, worse efficiency under heavy load (like towing) but still, one's mileage may vary. But judging from Fuelly data, it seems to be working a bit for the Ranger's 2.3L EcoBoost compared to other gas V6 mid-size pickups that it's put up against. (~19-20 versus ~18-19 - albeit subject to other differences)
Tuned for performance I can understand using turbochargers since they would be lighter than installing 6~8 cylinder engines and still have equivalent power rating. But fuel economy, it never made sense to me. At cruising speeds, the turbo is probably not even being used because of the lower RPM. Logically, if you're forcing more air in, you need equivalent amount of fuel to make power, and any savings or gains in MPG is most likely due to the fact that the base engine is smaller, not because of the turbocharger itself.

The takeaway? On bulk, turbocharged vehicles do live up to their fuel-economy labels. And they don’t suffer in the real world any more than naturally aspirated vehicles. That said, there are hundreds of cars, turbocharged and not, that exceed or fall short of the official fuel-economy numbers—some by 20 percent. The data largely vindicates the EPA’s fuel-economy methodology, but it’s an even stronger endorsement of that old axiom: Your mileage may vary.
Looking at the graph, I don't think I am convinced that Turbocharged engines are "better"

No one said they're "better", but there's a few reports confirming improved efficiency.
Cheap gas is usually the killer of the small jdm/kdm turbo engine head gaskets.

I too have had this be a concern come up, I've got a deposit on the sportage phev with 1.6L turbo but now I'm second guessing it's long term reliability, I dont know all the much about cars or engines but I'm trying to learn the basics for our next new vehicle purchase and thinking maybe the Outlander phev (2.4 NA) or a full ev might last longer? Thoughts?
