wow, seems I struck a nerve. it's basic physics. a V8 will never be as efficient as a turbo-charged 4 cylinder, all else being equal. that's the point of a turbocharger. sure, V8s are way more efficient than they used to be, but so are ICEs across the board.
you know V8's can get Turbo's installed too right? comparing an N/A motor to a Turbo motor isn't a fair comparison to begin with regardless the number of cylinders, a Turbo motor is naturally going to get a more complete burn of the fuel due to forcing more oxygen into the combustion chamber, Yes as it sits the Turbo 4 Cylinder itself is converting more of the fuel into usable energy vs heat, but the engine is only 1 part of the equation to the overall efficiency of the car, you have drag coefficients, gearing, horsepower to weight ratio's and the driver all effect how FUEL efficient a car is, My point is a V8 is not necessarily a "gas guzzler" (meaning poor fuel economy), it depends how it's used, you seem to be purely talking about the energy efficiency of the motor alone and using that to make V8's sound like the devil, my point is it depends how you use it, take for example a recent project from Legit Street Cars on Youtube, he bought a C5 vette and has been tuning it to get increased fuel economy on the highway with a target of 40 MPG which is about what our cars are capable of, as he achieves this he is traveling the same distance we do at the same cost of fuel but with a MUCH larger motor, I would argue that is being more efficient because he is using the same amount of fuel to move a larger vehicle even if on a Horsepower to Displacement ratio his engine efficiency is less.

Obviously you have to keep everything else equal when comparing vehicle efficiency, which is why I said "all else being equal". Comparing a V8 vette to a "tall" hatchback with different transmissions and drag coefffecients obviously is pointless, so I don't know why it was brought up in the first place. Turbo's don't achieve a "more complete" burn of fuel. in fact, at higher loads they often run richer than NA to help prevent predetonation. Turbo's only achieve higher efficiency by cramming more air into the chambers, which in combination w/ more fuel, allow them to create more power per combustion event. And where did I make V8's seem like the devil? I called them gas-guzzlers, which they pretty much are. Sure they have their place and they are way more efficient than they used to be. I love the sound of a good V8, but no one is putting a V8 in a small car and doing so to get good fuel mileage.

Because you don't buy just a MOTOR, you buy a whole car, so when speaking in terms of efficiency you have to look at the complete package not just the motor alone.

*ENGINE*... motors are electric

3rd winter in our 2018 Sport Touring 6MT (57 000km so far). I run the engine the time to do a quick removal of snow, then drive out. After a few km, the car goes almost in "Oven" mode, especially in Defrost or Defrost/Floor climate positions. When driving, the ambient temperature is set to 17/18 (above is too hot for comfort). Southern Ontario here and no big problem with the heat (and no oil dilution either).

I don't find this car to warm up significantly different than my old WRX, and that thing was far from efficient. I've always been of the "just drive it sanely" mindset until it gets up to operating temp.

I'm sure there is a sizeable class of people who are all for tightening the fuel efficiency standards at all costs, and who at the same time like to warm up their cars for 20 minutes while eating breakfast to keep their asses warm...:D

The 1.5T engine burns ridiculously small amount of fuel when idling. It's literally half or even less the amount non DI and NA engines of similar power would burn. There is no way to make a large displacement engine burn so little gas when idling. A V8 engine can be very efficient when going down a freeway, but there is no way it can even get close to what a small turbo burns while idling.

But the importance of the gas burned while idling has been exaggerated to a ridiculous extent in multiple media articles parroting each other. People living in cold climate may have installed gigantic natural-gas or propane - fueled blowers in their sunrooms with huge windows or in garages, may be overheating their houses and their floors so they can wear t-tshirts in winter and walk bare-feet, then happily blow the snow and leaves around with gas blowers, have fun driving up the mountains to ski and ride snowmobiles, drive around uselessly to get a beer, and then cry crocodile tears over idling the car for ten minutes...:crazy:

Which is why idling to warm then up is a bit of a fool's errand. I'm just glad to have headed seats!

In my civic all you have to do is turn it off before you leave the car. If you remote start it stays off
Well, in mine remote start will automatically turn on the climate control to bring the cabin to 72 degrees in any weather condition hot or cold. It doesn't matter if you turn off the climate control before shutting the car off.

Just turn off the climate control before you shut off & exit the car. It should stay that way when you restart the car.


Mine does not. It turns on the climate control to heat or cool the cabin to 72 degrees in any weather conditions.
