was wondering about a similar question just today....

do all 2026 and later BMWs have turbos? (excluding the full electric BMWs, of course)

[bpeckham]

Everything is turbocharged now.

I think the Japanese have lost their edge a little bit in reliability compared to the Germans. Before they had the luxury of doing things simpler and marketing their simplicity as reliability. Now their transmissions are 8 to 10 speed, instead of 4, they use turbochargers, have more plastics in the engine bay, and are using even thinner oils than BMW on some models. The B58 uses 0w-20, the Corolla uses 0W-8.

It's hard to believe that these changes won't change their overall reliability, especially since these changes are new to them compared to BMW which has been dealing with these changes for a while.

Might have been earlier than 2026. Maybe 2014?

The big difference is that BMW was first to develop a mainstream modern turbo gas direct injected mainstream motor with the N54.. they had a ton of issues but there was a ton of learnings that were later factored into the N55 and now the perfect B58... so yes BMW has nearly perfected this motor at this time.

Toyota had a headstart in the 90s along with Nissan but those were very old school motors that were never developed into anything modern and as a result they are now way behind because they stuck to simple is reliable... today's world expects different.

Toyota and Nissan are in a different market than BMW. BMW’s are much more expensive and the buyers have much higher expectations. Buyer’s in the Toyota market value reliability, fuel efficiency, and competitive pricing.
In other words plastic vs carbon fiber.

i am not sure how the reliability conversation comes into play here... toyota buyers are arguably the most demanding when it comes to that... Toyota failed miserably there w the turbo motors

thats the one paired to the Tacoma which unfortunately has transmission issues... and that engine is quite complex if you see the number of hoses and pipes on it... so we'll see

[arch6717]

B58 is proven reliable, many of Toyota's turbo engines have issues (Tacoma, GRC, Tundra).

This is so glaringly bad for Toyota, and the worst part is they still can rectify the situation.

Yes, for the US market - every 2026 BMW with an engine is turbocharged.
The only non-turbo, non-electric BMWs now are the plug-in hybrids in EV mode, but the engine itself is always turbo when it kicks on.

If you’re looking at EU or other markets, the 1.5L 3-cyl in the 118i is also turbo. NA is basically gone from BMW’s lineup.

So if you’re buying new in 2026, assume it’s turbo unless it’s a full EV like i4, i5, iX.

The last NA engine (anywhere) was N52/N53 which ended in 2015 with the F01 730i.

Absolutely. My mechanic was a rabid Toyota fan. I think he worked at a BMW dealership before he went independent. He is very good and honest. He likes me and my wife so tells us to buy Toyotas and Honda. He is in a depression about these awful twin turbo Lexus & Toyota engines. They not only fail quickly but they are underpowered and get bad gas mileage.

We took a relative's 2018 4Runner to him and he loves it. He did an oil change and checked everything. We went back the next day. He said the guys at the parts department said the dealership will not take twin turbos in trade! I said you have to be kidding and he said no.

I have a neighbor in our development of 240 homes. I was exiting the development and he has a new RX550 Lexus (SUV truck). He wanted to speed so he passes me on a double yellow line. I almost floored it because my N55 is about 1.5 seconds faster to 0-60. I let him go.

I looked up the specs on these new very expensive Toyota SUV/Jeep things versus X5 and X7. BMW's are now about the same price. Using a B58 in the X5 or X7, the BMW's versus the RX550 got an average of 5 mpg better gas milage and 0-60 was about 1.7 to 2 seconds faster.

You have to also think they are underpowered and straining so they will burn them up faster.

The N54 won engine of the year 3 years in a row, I believe...it's just the supporting parts sucked (HPFP, fuel injectors, oil filter housing...)

I'm past 16 years and 334,000kms w original turbos and still going strong (knock wood).

I think Toyota has some catching up to do with their Turbo engines. Turbo lag was a bit of a complaint on the IS200T and NX200T when they first came out. It was around the time when Lexus got rid of the 2.5L V6. Now with Toyota getting rid of the V8 and switching to a Turbo 6, that engine has been getting a lot of bad press and the reliability of that engine is shown to be poor.

BMW had some teething issues when they started mass turbo charging their line but that has been resolved and you can see that on the F8X and F3X platform and that only gets better on the G8X and G3X/G2X.

Since I dealt with Toyota Corporate a lot on my last car (Scion FR-S) (like 20+ service visits) due to reliability and warranty issues, I really hate the way they handle things. They would rather keep throwing money into fixing the car than buying the car back.

I got to know the Longo Toyota Service Director Paul Le Blanc, Service Manager Rob McGuire, and Shop Foreman Sam Walton quite well due to my last car.

Toyota NA engines good. Toyota turbo engines TBD (but not looking so great).

I generally like Toyota. They came out like BMW and said that they were going to keep doing ICE, PHEV, some EV and also doing hydrogen/etc. This was a great move. Honda had a similar attitude.

BMW has decades of experience starting with Bob Lutz putting a turbo in the BMW 2002. This was before the Porsche 930. Supposedly, Oldsmobile had a turbo engine in the 1960s(?) but never really made it. The Group 5 racing 320i with Hans Stuck driving putting out close to 650 bhp.

BMW has even more experience taking a little 2002 4 cylinder M10, slapping a big turbo on it, using rocket fuel (BMW/BASF Wintershal fuel) and putting out 1400 bhp in qualifying mode thanks to Paul Rosche wizardry. The engine was the M12/13. I think it race mode it was 700 bhp.

There is the engine, and then there is the maintenance necessary to keep it going for 200+K miles. Turbo engines run particularly hot, frequent and quality oil changes are critical to keeping them going forever. BMW S** engines are the best at it, courtesy all the extra cooling and oil capacity, and cooling fans that run after engine shut down.

BMW's cooling system has been an ongoing problem space since E36 days. Those plastic parts get extra brittle from the extra heat. Now add plastic valve cover, intercooler, etc.

Toyota V6 turbos are going through main bearing pains, especially on US assembled engines and cars. Japan built engines and cars are rock solid. Hybrid Toyota engines have been pretty bullet proof for a decade plus.

Just following BMW or Toyota recommended 10-15+K mile oil change intervals is not good enough with turbo heat cooking the oil.

I don't think that's true.
Toyota includes Lexus, with customer base and expectations undistinguishable or even higher than that of BMW buyers.
BMW includes X-series many of which are cheap and sub-Toyota quality.

Majority of BMWs (60+%) are leased and barely (if at all) maintained. Lease, drive, trash, start anew in 2-3 years. Thus, buying a used BMW is a higher risk proposition than buying a used Toyota.

I would not buy either used without a PPI and access to PO's maintenance records.

YMMV,

P.S.: Currently own 1 product of each brand.
