2025 4 cylinder sounds awful to this 2022 4R Owner!

[Nodak]

Thank you. Didn't know we can pay per month. That'll work ?

looks like they raised the 1 month to $15 from $10

3 month to $30

12 month to $60

I would be very interested to know what people would say about the engine after driving it if they didn't know what kind of engine it was.

I think a lot of the criticism of the turbo 4 is confirmation bias, they want a V6 or V8 and don't believe a 4 cylinder is appropriate for this vehicle.. The OP stated they have a 22 4R and although the 4.0 V6 is bullet proof it has never been a nice sounding smooth engine. Then there are the comments about being underpowered and gasping for air. It's more powerful in HP and torque than the outgoing 4.0 V6 and having forced induction it's never gasping for air, even at altitude.

Still waiting to drive a TRD Sport or Limited, but to respond:
I think I already mentioned (somewhere here) that I don't expect 4 cylinders to sound like 6 and agree that that the old 6 when pushed isn't exactly quiet. My point was that the Tacoma TRD Sport and LC 1958 had unpleasant noises during relatively mild acceleration (I related it to valvetrain sounding like a sowing machine, another reviewer mentioned a tractor like sound. Either works.

I agree performance wise the Turbo 4 is a delight, especially torque.

My point was/is that I know what Turbo and Supercharger noises sounds like, I know what my RAV 4 Platinum sounds like, so if i isolate turbo boost sounds, there is no need to hear the valve train rattling away the way the cars I test drove did. It's a matter of sound isolation and insulation under the hood and at the firewall.

My daughter and probably my wife, would agree on the comments about turning the music up louder. However, the engineer in me likes to hear an engine performing well (including turbo boost and occasional blow off) and my daughter who has 2 V8's would never buy a 4 banger turbo or not! My son is much the same, 2 V8's one with Twin Turbos he installed and an Audi turbo, no tractor noises there

Anyway, my fingers are still crossed about real world experience of driving the model I'm interested in.

I don't mind the noise of the engines, I find it comforting. It's any large mid air turbulence that bothers me.

Actually yes, I almost went to work for RR aero engines as an apprentice, many years ago.
I'm fascinated by turbine systems and how pure jet vs low and high bypass fan, and Geared TF engines operate. When you understand how they work and what makes a wing fly and varying lift by speed or as slats are extended or retracted - it takes away concerns about the different sounds you hear when flying.
At least for me

IMO, Toyota 4 cylinders have never been smooth operators. My Camry is my first Toyota (driven and ridden in many Toyotas however) and previously owned a several Honda products. Honda 4 cylinders are much smoother in operation than Toyotas, by a lot. Toyotas are just as reliable as Hondas but their 4 cylinders are more agricultural in NVH. The K24 in my Acura, even at redline, is silky smooth; not so much for the 2AR in my Camry. The NVH of the engine was the second thing that went on my "don't like" list; first was the programming of the transmission shift points.

However, if the T24A in the the 4R sounds agricultural like all other 4 cylinder Toyotas I don't think it would bother me as much. Being a truck (it's body on frame just like a truck) it's not out of place to have an agricultural engine. For example, most people loved the roar of the clutch fan on Toyota trucks. Big diesel pickups have that distinctive clatter that sounds good. If you were driving a Highlander or a Lexus RX those same sounds would be offensive. I think this is how the T24A got the bad sounding reputation, in a Highlander or a Lexus RX you don't expect to hear that roughness. But I kind of expect a truck to sound agricultural and not whisper quiet.

Also, maybe everyone else knew this, but I just found out Toyota manufactures the turbos in house. This means the T24A's turbo was engineered specifically for this engine. Most manufacturers buy their turbos from suppliers, Ford uses Borg Warner and I think Honda uses Mitsubishi. But Toyota engineering and manufacturing both the turbo and the engine together in house should give it an advantage in performance, efficiency and most likely longevity.
