There's a lot of this incorrect info floating around in the EV community. I recall one person, a year ago I think, trying to claim that gas cars won't start in the cold.

Not -50F either. 10F and such.

Similarly I've been told my EV won't last a day when the winter comes. I live in Houston lol.

I really don't consider myself part of any "EV community"; I'm an EV owner who has owned/bought several gas cars prior (most bought new, so I saw the efficiency drop over time). That said, most of my cars were of the highly efficient variety, Honda Civics and the like, so it may be more evident than in trucks etc.

The common retort I suppose is that if my efficiency went from 38mpg to 33mpg that I must be doing it wrong, similar to how a discussion on location of chargers devolves into a highway driving being an endurance sport, where everyone gets 600 miles of range, fueling up their cars in 3 minutes, with no need for any form of urination.

Gas cars do have trouble starting at cold temperatures though? Ironically it's often due to the starter battery.

Gas cars have absolutely zero issues starting in the cold, unless the battery is not good enough, or the car has another mechanical issue. EG, the car is broken.

To say it's because of the cold, is like saying they have trouble driving on flat tires too.

As a Canadian, who's been driving cars down to -45C mornings for decades, they just start. Older cars, and I don't mean "cars that have aged" but instead "cars from the 60s or 70s" sometimes needed a "block heater", which was basically just a fat resister you'd plug into AC. It kept the engine block warmer.

However I must reiterate... that's not commonly required any more. Not for 50 years.

Diesel cars don't run very well in the cold. They still work though unless it's super cold.

Diesel cars work perfectly in the cold. Once an engine has warmed up (half a minute), then it's the same for the car as if it was 30C outside.
