[My Honda]

It looks like Honda cars are designed to take a much longer time on warm-up at cold temperatures to get rolling ready. My 2014 Accord Sport takes several minutes at idling around 40 F in CA to get the odometer reading from 1,600 RPM to 1,000 RPM when the temperature needle sits at the first mark and the car can get ready to roll. That is way too long. On top of that, I feel like the car loses a lot of power in a cold morning because it moves very slowly 15-20 MPH for the first few minutes. In contrary, my wife's 2016 Toyota Camry XLE odometer drops down to 1,000 RPM in just 10 seconds whether it is hot or cold out there and it is ready to roll just that!
I read an online comment sometimes ago saying that Toyota cars use a different kind of radiator fluid that makes the car warm up faster. Thinking if we can use the same radiator fluid that Toyota have them on their cars to shorten the waiting time and get rolling faster.

First off, why are you waiting more than a few seconds before departing? 20 - 30 seconds of warm up is more than enough, just drive a little easier for the first few miles. If your car is not up to operating temp within a mile or two I would look at your thermostat if it hasn't been replaced. And no toyota doesn't use a coolant that is made to warm faster.

This. As with almost any modern car, unless you live at the bottom of a freeway entrance ramp or something, I'd just get in and drive it gently until its at proper temp. I've lived in the snow belt my entire life, and the only car I ever had to warm up was my 1984 Accord (to be fair, it had an issue with its carburetor that impacted performance when cold).

Keep in mind that newer engines in general are more thermally efficient. Excess heat is wasted energy.

The main reason for warming up was carburetors in those days.

My '09 Nissan Frontier (fuel injected) has a fast idle cam that operates when the engine is first started after not being run for a few hours. On that I usually let the engine idle down before putting into gear and moving. On my '15 Accord V6, I haven't noticed this and just take off right after starting it.

First, +40f is not cold.

Second, want heat immediately (or as fast as possible)? Get in, start up and drive off. This is true at all temperatures. Working the engine creates heat faster than simply idling. Much like I sweat when doing physical work, but don't sweat when here at the keyboard.

Finally, the odometer measures distance. The tachometer measures engine RPM's.

My car takes around 1 minute of idling from cold starts to drop down to 1k rpms, seems like you might have an issue. I have a manual so I don't have remote start and just wait a minute or so until the rpms drop and start driving. Just don't go over 3k and the car will slowly heat up. Takes around 5 minutes everytime for the heat to get going. Idling isn't gonna do much if you want heat right away unless you have remote start and start the car for 5-10 mins everyday. At that point, you might as well get in and start driving. Just bundle up and wear some gloves cause it'll be cold.

Sounds like you have a thermostat that is stuck open.
