ENGINEER PREDICTS 2025 4RUNNER'S DRIVING FEEL - OFF-ROAD & ON-ROAD DRIVING CHARACTER DISCUSSED

How would the all-new 6th Gen 2025 Toyota 4Runner drive both off-road and on-road? That is the question Automotive Engineer David Chao answers through his often-accurate predictions based on his analysis of other similar TNGA-F vehicles. David discusses in detail the off-road capability of the new 4Runner based on his experience driving the new Tacoma which shares the basic architecture... and then for the latter half of the video David talks about the difference between the 5th Gen and 6th Gen 4Runner in terms of the on-road city/highway driving feel.

⁠ I have a 2024 4Runner ORP with KDSS. The Body roll is similar to my Lexus ES 350 sedan. My 4Runner is not slow around corners, nor is it scary at highways speeds on a curvy road and it never feels it will tip over on quick turns!!!! It is great on the highway and I overland/off-road and it is fully loaded. I bet my 4Runner will handle curves and turns better than 2025 model because there is no KDSS option on the 2025. But the 2025 GX 550 has KDSS. As far as underpowered, I have gone hours driving at 75 miles on the highway and through mountain highways. NO Problem with power!! Have no issues merging on highways. It lives up to its 4Runner heritage and exceeds my needs for overlanding and off- roading. David, I guess for drivers like you who mostly use the 4Runner as a mall crawler more power would give you more driving enjoyment. But What a waste for a 4Runner! Better suggestion why not get a Corvette if you want real power. I had one, but needed a 4Runner for Overlanding/Off-road that will last for many many years. Corvette could not do it. David, I am getting tired of your biased propaganda Toyota reporting so you can stay in the good graces of Toyota and the engineering departments. The 5th generation 4Runner is great for overlanding/off-roading and is proven to last many years.The 6th generation has no track record … questionable 4 cylinder engine, terrible tires for off-roading, a battery that takes up valuable space in the trunk, seats that when folded down have a big awkward hump, and doesn’t come close to folding flat, a roof rack that is not full length and for me would needed to be replaced…. My 2024 off road premium with KDSS, rock rails, cameras, Wildpeak All-terrain E rated 10 ply tires is better for my needs and how it was delivered. Also later added a full length roof rack UpTOP overland. All for under $52,000. I am happy!

risky buying first year of new powertrain design. 5th gen does what it is designed to do well, is cheaper, lower operating costs, easy repairability, great resale.

[@Zenergist]

I bought a 2024 4runner because i didn't care for some of the design changes. 4 cylinder + turbo, backseat space, back seat folding, over reliance on tech, and amd guaranteed higher prices. That being said, it seems like the engine power band will be improved. Hopefully not at the cost of reliability.

[@thebigempty_5792]

No one seems to be mentioning the loss of the GATED shifters. Toyota changed them to a thumb press style. It's easier to shift between gears with the old GATED style, especially when off roading or when it requires your attention elsewhere other than looking down at the shift knob. It may also be harder for people with arthritis to be required to squeeze the button in order to change gears. Just a thought.

[@ejshelby5460]

I second this. One thing old school I loved about the previous Toyotas is the gated gear housing. Very mechanical feeling and clicks in place. The new airplane style has strong locking sensation too and is probably the best straight line shifter among all makers, it does feel like a plastic toy.

2020 TRD Off Road w/KDSS. I like the Trailhunter package and color. All zooted up, but robust and reliable are my priorities as mine is my long trip and off road 2nd rig. The 2020 really fits the bill well and load capacity/layout too. Niggles with the new. Raised rear floor/load height for the hybrid. Placement of the compressor outlets. Also I have never really driven any turbo that is transparent in driving feel. I like the fact the non hybrid is still more powerful than the 6 but the grill appears to me hideous. Cosmetically the Trailhunter nails it while the Pro not so much and the grill on the non hybrid, at least in the images not a draw. So for mountain bikers or cyclists who haul a bike inside the new may not be a winner sad to say. Even for hauling goods higher up just is a pain. Practical cargo space is paramount in a SUV. So all the driving and modern improvements may not make the new rig a compelling buy if one owns a 5th gen. I can afford one but my priorities are reliable and robust along with practical storage space. That Trailhunter compressor, from what I've seen has it midway forward of the right sidepanel. Not facing the rear, so if one is loaded up, one cannot access the compressor! Just my thoughts. Appreciate the review on the basics and can't wait to see a more detailed update with the real thing.

[@jre617]

How big is the fuel tank in the new 4Runner? The new LC has a smallish 17.9 gallon tank. That's a poor 370 mile range based on C/D's mediocre 21 mpg in their 75 mph hwy test. (Grand Cherokee V6 is 500 miles, and 22 mpg.) However, the Lexus GX has a larger 21.1 gallon tank and a more usable 440 mile range. I suspect the LC's smaller tank is due to the battery in the back, so I assume the larger hybrid engine in the new 4Runner has the smaller tank and similarly poor range? Kind of a deal breaker for road trips.

[@Mongoose1212]

Can your next video be on when you need to change Toyotas CVT transmission fluid and how often ? Toyota is not very clear about this and some people do it every 60k miles while others don’t do it at all. would an suv vs car matter? What would maximize life on the car ?

David never drives a 4Runner with KDSS, big difference. It will drive better than the 2025. KDSS significantly decreases body roll, never feels like it will tip over on sharp turns, or and issues on curves on highways. Drives great on highways and the body roll is similar to my ES 350 sedan. The 2025 does not have a KDSS option

Hi David!😊. I just heard the 6th gen 4Runner was delayed again. Is this true? As I mentioned before, I got my license nearly 14 years ago, and have had an FJ Cruiser and two 5th gen 4Runners, in that time. I had no intention of buying the 6th gen 4Runner, even before they revealed the new Tacoma. After spending 2 years daily driving a Defender, I knew I wanted a body-on-frame SUV with the off road capabilities of the 4Runner, but with modern luxury and great interior like Land Rover. The GX 550 answered my desires, for something that balances both, perfectly!

[@AutomotivePress]

You've definitely been a loyal body-on-frame Toyota owner! I agree that no matter how good the unitized body SUVs get, I still prefer the feel of the true body-on-frame SUVs. I'm still planning to buy the GX too, but might delay it now that I have the Land Cruiser... can we take both vehicles (your GX and my LC) out to off-roading courses and do a real comparison? And yes the 6th Gen 4Runner is delayed by at least 3 to 4 months due to parts shortage, could be longer.

[@lunamaria1048]

@@AutomotivePress There is really no real off road comparison. The LC has an advantage because it has an excellent approach angle, but the GX 550 retains the same bad approach angle as the 460 had. In person it looks like the 550 has a bird beak, when compared next to the LC's nice approach angle. I bought the GX 550 as a daily driver/weekend adventure Defender alternative (not as a 4Runner replacement). Utah has countless miles of easy trails and in the desert trails, breaking down can be fatal, because of heat. I am talking trails that a Rav4 could drive. No crazy rock crawling or technical stuff. Driving it from Utah to Vancouver was fun! I went through Oregon to drive my favorite trail there. The trail can be driven by even a Subaru or Rav4, so nothing very technical. I will not be driving the GX as I drove my previous 4Runner. I sort of have buyers remorse, but we will see how things go. I keep my adventure rigs for years, but I have always been very fickle with daily driver ownership and never keep them long. We will see what happens lol

I love the look of the new 4Runner’s. My only hiccup with the Trailhunter is apparently it comes with no sunroof. For me personally I wouldn’t buy it so the million dollar question would be, could I buy a luxury 4Ruuner and build it up to come close to the Trailhunter and be able to get a nice sunroof along with some luxury features built in. Have to wait and see and if so, that’s a home run for me. I do a lot of driving during the week for my job so I dont need to be tossed around a lot either.

6 Gen 4Runner, Lexus GX or Land Cruiser. Decisions, decisions. Main concerns reliability and utility

[@RJ-vc2ju]

Thanks David. I'm willing to consider your praises for this 6th Gen, but I'll have to see for myself. You don't drive or review vehicles as someone that is a very experienced off-roader, so your perspective will mostly be valid for those that will use this as an urban SUV with outings to the local gravel roads as their most extreme off-roading situation. Hopefully Toyota gets the pricing correct, with the Trailhunter and TRD Pro number starting with a 5 in the US and a 6 in Canada, all in, fully optioned, and out the door. The chances of that are slim and it is likely that Toyota will do exactly what it has done with every new SUV/truck since the new Tundra, which is to give the consumer more gadgets, less substance, for much more money. It's a great approach especially in North America as our consumers tend to be easy to distract and sway with gimmicks.

[@TheSolderingGuy007]

Undecided between GX500 and 4Runner. How bad is the ride quality of 4Runner expected to be compared to GX550 on road ?

[@Jim-s6i3b]

GX 550 has KDSS on certain models so it will be definitely better ride on that alone. No KDSS option on 2025 4Runner. If you want a better ride on highway on curves or a better turning vehicle with less body roll the 2024 4Runner with KDSS would be better than a 2025 4Runner

[@willhaven1337]

David, I'd be curious what the Toyota engineers think about a manual transmission option in the new 4Runner. I had high hopes since I knew it shared a platform and drivetrain with the Tacoma, but was let down when it was announced and appears to be automatic only. I wonder if it's a product/marketing decision, a logistical issue with where it's built, or a technical limitation.

[@ericmcleod7825]

I'm not David but the answer is that there is very little customer demand for manual transmissions. Most people under 30 do not even know how to drive a car with a manual transmission.

The Car Care Nut comes from a different direction, i.e. reliability and ease of working on things; I respect his opinions, but I am an end user. However, most now will objectively acknowledge (even the General Manager at the dealer who sold it to me!) that the transmission gearing is not mated well to the V6's power/torque generation. E.g., the 4Runner is always looking for a gear it does not possess (perhaps unless you live in the flats at sea level). It also tows like garbage at altitude in the hills (it'll do it, but screaming around uphill at 4500RPM). I'll posit that the ECT was programmed by the same summer intern. Enjoy your purchase.

895 lb payload of 2025 4Runner is a dealbreaker. It is much less than the 1625 lb payload of the 2024 4Runner, or the 1411 lb payload of the Land Cruiser. 4 x 175 lb adults leaves just 195 lbs for gear in the new 4Runner. Tow a 6000 lb trailer with a 10% tongue weight leaves just 295 lbs for people and gear. The new 4Runner is certainly sporty but Toyota took the “U” out of this SUV. I’m looking at a Land Cruiser to replace my old 4Runner, and I’ll live with its reduced cargo capacity.

[@JackieGleason-kv4xi]

@@JackieGleason-kv4xi I was being generous. Using a higher weight makes the 4Runner payload even more ridiculous. 175 lbs is closer to the average for all passengers, not adults. The latest FAA standards increased an average adult passenger and carry-on bag weight to 190 pounds in the summer and 195 pounds in the winter.

Turbo engines are inherently more complicated. More failure points, higher temperatures and pressures.
