Will the "old" engines return?
With the Trump killing of all that old greenhouse gas emission standards for the auto industry, will they replace those silly engine shut off models with the regular engines again?
I'd be shopping for a replacement of my Toyota 4runner, but refuse to buy anything that shuts down on stops. Which is basically everything out there now.
Would it be as simple as just a programming change?

I'd be content with the trend towards everything being a small four cylinder with turbochargers stopping. Especially in trucks of any and all persuasions.

Since most of the cars with the auto shut down/start up can be manually disabled once the car is started, I would assume it could be fixed with a software update.

The big thing will be to get rid of the ethanol contamination in gas.

Just give us straight unleaded.

There is a lot of talk on the web about the possibility of an over the air update to disable the start stop feature. Also, if a particular model can’t accomplish that then a quick trip to the dealer might fix it once it becomes available. There is also a possibility that some of the 2027 models may have that removed…

Was that an emission thing? I was under the (possibly mistaken) impression that it was for fuel economy.

Yeah, Mine doesn't do that, but I'm sure everybody gets better mileage than I do.

I've read (sorry, don't recall where) about a dongle that plugs into your ODB port and disables the auto-off crap so you don't have to do it manually every time you start the car. I'd think it could be done via an OTA programming update, but I don't know if that would affect the MPG numbers the manufacturer can claim.

Killing off V8 and V6 engines and the move to turbo fours was primarily because the older engines couldn’t meet stricter emissions standards imposed by the govament (Dem climate worshippers).

Gas mileage was a consideration, but that was secondary.

Hemis ain’t coming back.

Hemi's are most definitely coming back. The problem with turbo engines is the do really well in the EPA tests which are proven to be unrealistic driving conditions and when driven like everyone drives them they don't do very good. Essentially if you have to move 4000lbs from point A-B it's going to take a certain amount of energy and the engine size isn't as much of a difference as we would think.

Anecdotal but out of our 3 cars my V8 gets the worst mpg followed very closely by our Turbo 4 and then the best by a pretty large margin is the NA V6.

It really depends. This will help our domestic manus but many models are world models. IE, they sell it in many countries around the globe. Unless the other countries relax their emissions standards (they will not), I highly doubt it will have this huge effect.

What it will do is curb costs and stall the ever increasing mpg/emissions standards. Hopefully this will mean less expensive vehicles for the USDM, but as greedy as the manus are, highly doubtful. Manus will likely keep pricing the same, and take the profits for themselves instead of giving the customer a cheaper price.

I don't have a cite for it but I thought I heard a few weeks ago Trump had ordered the auto shut off to not be required.

I was just looking at a 2026 Dodge Charger Scat Pack on my dealers showroom floor. 64K. And its not a Hemi. Twin Turbo V6.

This. There were some very reliable engines and now so many are DI, turbo charged that will not go the distance. Same with a lot of the transmissions with 8, 10 plus gears. Not even going to mention CVT’s.

YES!!! I agree completely, this and the auto start/stop has killed any interest I have in getting a new vehicle. I maintain and keep vehicles typically 10-15 years minimum these small turbo engines doing the work a 6 cylinder should be doing is not good for long term in my opinion.
