Yes I did flag the issue.

The hybrid option seems to be very likely. I4 certainly plausible. Turbos are fine, I think. Depending on how hard they are designed to work and are pushed, you may have to replace them (in something like the 4R) every 150K-200K. In a towing or heavy vehicle, maybe 120K-140K. It is prob around $1,600-$2,200 to replace two turbos.

I'm very curious to see what they do. Deep down, I keep wishing for a big diesel in the Tundra but in the 4R, I prob want a hybrid...way better torque and way better MPG and resulting range, though at a higher initial cost.

I sure hope there is no 4 cylinder turbo. 4-cylinder turbos (in my humble opinion) are only for small-medium sized cars.

Larger SUVs/Trucks/Crossovers need more displacement.


Ford has done well with their ECOBoost models on the F-150, but most small turbo engines have too much lag.

Yes I know there are exceptions and I'm sure plenty of people will let me know what they are.

I'm just saying that I would not buy a 4-cylinder turbocharged 4-runner.. UNLESS it were 3+ liters. If it were 6 cylinders and turbocharged, heck yeah.

But Toyota seems obsessed with small and hybrid engines.

And these days, I'm seeing a lot of car brands add turbo engines to the lineup, but they always put it on a SMALL engine!

My wife has a Kia Sorenta N/A V6 3.3L I think. Has great torque and HP. The new model will offer a 2.5L turbo. That's a pretty good start, since they currently offer a 2.0L turbo. But I'd much rather see that as a 3L turbo, preferably a 6 cylinder. Not picky on V6 vs. I6.

I know these companies are doing it for their fleet mpg ratings.. but I WANT a turbo engine that isn't some tiny little engine that should be on a compact car!

I want it all

I think there is no getting around the turbos and hybrids. The 3.5L Ford EB has very little lag and is great around town and the highway 90% of the time. It is also pretty quick. I had an Expedition and have rented a F-150 EB many times. I have driven the 4 cylinder EB in the Mustang many times...quite a punchy motor as well. The turbos can be tuned to kick in very early. I wish diesel wasn't so polluting. More and more diesels and hybrids would be common. The hybrids are nice. The new Ford F-150 with its PowerBoost motor is FAST and has some serious torque over its V8 gas brethren.

Of course, I'm saying all this as I drive a huge diesel.

It’s funny how psychologically it affects people’s choices seeing/hearing about an i4 engine in a truck. If you ever drive one that fear goes away real quick.

For me personally, an I-4 is fine. I'm fine with low power and slow acceleration since I don't tow anything and am not in a rush. Heck, I owned an '88 with a 22R-E for 300k miles. People passed me on bicycles ;-) I simply don't want a turbo. The fewer possible failure points, the better, IMO.

Turbo 4 could be cool.

Cobb tune that shit.

My Cobb tuned Macan 4 banger makes over 300hp.

turbos add power but also require more fuel, only at part load are 4 cyl turbo more efficient than v6

Turbo 4 sounds good to me, can produce plenty of power while increasing mpg.

Would Turbo require Higher Octane Fuel which is a Lil more $$$? Had to with my '90 Grand Prix Turbo.

More than likely it's going to be an I4, maybe a Turbo'd I4 with a hybrid drivetrain. Which I am thinking is a mistake on Toyota's part, but they're locked in on making their entire line Hybrids going forward (if the Sienna is anything to go by.)

I doubt they'd put the twin-turbo V6 from the Tundra in the 4Runner, it's too "big" of an engine for their plans going forward and they axed the Land Cruiser in the US rather than pull over one of their nicer Diesel options from overseas.

I imagine the 2023? 4Runner will be rather questionable for a lot of prior 4Runner owners.
