One of the reasons that turbo engine will not last as long as a NA, even so much stress placed on engine oil:


So to me it’s not the V8 vs V6, is the turbo that takes way the predicted long term reliability of the engine.

 

‘I don’t think long term reliable will be a problem for Toyota. They out last all out brands. And Toyota has had turbos for 40+ years. The issue is the downsizing of engines. It is just inexcusable for the LX. My 04 4R has a turbo option in other parts of the world. Lexus had a turbo in the last gen LX model but it just wasn’t sold here. Land Cruisers have had turbos for 40 years. Supras as well.

 

Anyone else notice there are more new last model on the road?

 

Clearly shows where the marketing demographics are aimed at. This showed up today.

 

Sophisticated architects

 

youll just have to change the oil more often, but lot of people out there cant even change their NA oil on time or use a good synthetic

Let's not forget the turbo wastegate fiasco with the recent Tundra which shares a version of this exact engine. And the LS500 upon its debut also had engine issues.

Other companies have been able to make reliable, better-performing turbo engines because they've been at it longer (in the modern context, not 1980s-90s), Toyota still haven't proven themselves. Naturally aspirated is where they shine, turbos not so much.

EDIT: LOL, didn't mean to reply to a 7-month old post. But my point still stands.

 

You are wrong. Toyota has been making turbos consistently since the 1980s. You just don’t see them in North America. My 4Runner V8 also called Hilux Surf had an inline 4 turbo diesel. Toyota Soarer had not one but two different turbos up until 2000. The outgoing RX had a turbo engine, Toyota Corolla had a turbo (gas and two diesels) in the mid 2000s. My gen Corolla had a turbo gas. You just never knew

 

Toyota did market the MR2 Turbo here in the U.S., back in the 1990s.....my ex-Flight-Instructor had one for several years. And the 90s-vintage Toyota Previa minivan had an optional supercharger.

 

I said "modern context." Also turbo diesels behave nothing like turbo gas engines.

Toyota is still a greenhorn to widespread usage of turbo engines. Only now are we actually starting to see them implement them en masse in vehicles like the Highlander and RX. Other brands have been putting small displacement turbos across their entire range over a decade ago.

 

The question is, how long does it need to last? Very few cars are still on US roads with 300k+ miles, no matter how long lasting they may be. I have never owned a car past 220,000 miles, and then only a few cars. If you're telling me a NA Toyota engine will last 700,000 miles and a turbo will only last 500,000 miles, thats a big whoop IMO.

 

700,000 miles. It doesn’t need to last that long. But it needs to meet past expectations of Toyota ownership where the engine is rock solid for 10 years minimum(with normal type miles). At 15 years…you’ve got a future buyer for life, that is how the Toyota brand gets the following it has. Other brands get their following from different attributes. I would never buy a Toyota or Lexus if I didn’t want to keep it for a long time (10 years). I’d buy something else. And leasing. I’ve never understood why someone would lease a Toyota or Lexus.

 

National average miles driven is 14,000 miles, so after 10 years it will have ~ 150,000 miles on it, these turbo engines are going to be just fine at that mileage. As for people "buying them for life", thats overstated...like I said you don't see a ton of cars running around with 200k+ miles.

 

at the rate you buy cars, i don't think it's making a big difference to toyota/lexus either way.

then perhaps you haven't had a car for a business. leasing makes a lot of sense. and of course many people have no interest in keeping a vehicle a long time, so leasing is less money up front, move onto something else in a few years.
