Why are engines more efficient in cold weather? Now, cold air is denser than warm air, so in cold weather the number oxygen molecules entering the combustion chamber per unit volume of air is significantly greater than when the temperature is high. More oxygen provides better combustion, and hence a noticeable increase in power.
Is cold or warm engine more efficient? Any engine is efficient in cold as density of air will be higher at lower temperature. More mass of air inside i.c engine more will be the pressure after combustion.
Are engines less efficient in cold weather? Engine and transmission friction will increase in colder temperatures due to cold engine oil and other drive-line fluids. This means it will take longer for your engine to reach its most fuel-efficient temperature. This will affect shorter trips more, since your car spends more time in less-than-optimal temperatures.
