This article sounds like it was written by someone with very little experience owning cars or living in a cold climate.
Air gets denser as it cools, which takes more work to push through.
Dense air contains more oxygen, making IC engines more efficient. Air isn't "pushed" through an engine, it's drawn in through the vacuum effect on the intake cycle.
Moreover, most of the complex parts in a car that require viscous fluids do not exist in a BEV, i.e., no engine or transmission to worry about.
Sure, but EV cars still have lubricants (including in the motor). At cold temperatures their viscosity increases, reducing the efficiency of the vehicle overall. Maybe it's less than a conventional vehicle but it's entirely speculation on the author's part.
Ten minutes of shivering as you wait for the engine to warm up is a thing of the ICE past.
Perhaps the last time the author was in a motor vehicle was in 1998, but "ten minutes of shivering" has not been in a thing in any IC car for a very long time. Modern cars also have resistive elements in the heater for this exact scenario.
"Because we have some bandwidth there, we like to call it an advanced heat pump system," Cansiani says.
Want to know what else is a heat pump system? The climate control in an IC car. It moves heat from the engine to inside the cabin when needed.
You need not worry about tailpipe emissions poisoning you in your garage because there is no tailpipe.
Once again, it's possible to warm up an IC car without running the engine. It's called resistive heating and it's been around since electricity was invented.
Internal combustion engines only offer acceptable response, as so many variables play a role in power delivery: air temperature, humidity, air quality, fuel quality, not to mention vehicle speed and gear selected, which determines engine speed. And, again, those pesky viscous fluids and their current temperatures also affect engine and transmission performance. All of that affects how quickly engines respond to the traction control system's needs and how accurately.
Finally, an advantage that electric motors have in snowy conditions! Unfortunately, the author attributes this to "those pesky viscous fluids!" which is just completely wrong. Electric motors can respond to changing traction much more quickly and accurately than gas engines, primarily because AWD systems can place one motor on each wheel and respond hundreds of times per second, which an IC engine can't do.
Just a really badly written article from someone who should not be writing about technology. I get that car manufacturers are struggling to sell EV cars, and that an entire party's platform rests on everyone throwing away their ICE vehicles immediately and trading them in for heavy, mining-intensive, but virtue-signalling EVs. Lying about the benefits will do more long-term harm to the climate movement though.
Edit: Apparently arstechnica (lol) felt the need to pin a comment defending the article and the author. If it's true that the author worked as an automotive engineer then he should be ashamed for writing such a bad article, from both a technical perspective and a journalistic perspective.
