How do I love thee, EV? Let me count the ways.
The InsideEVs community can probably all agree on one thing. That is, electric cars are better than those powered by internal combustion. But, we all have friends and family who might not be willing to take our word for it. Well now, you have an authoritative voice to point them to if you've been less than successful in your attempts to convince naysayers.

That voice belongs to the host of the YouTube channel Engineering Explained, Jason Fenske. The channel's latest video is the 5th and last of a series produced in conjunction with Formula E and features his dulcet tones explaining five ways that electric vehicles outperform gasoline-powered ones. You can watch above.
If for some reason you can't watch the video right now, we'll break it down quick and dirty for you.
- Instant peak torque. Probably the most often repeated advantage. Power comes on so hard in electrics that they have feather the intial onset so driveline parts don't get destroyed.
- No complex transmissions. Yeah, you can put a multi-speed gearbox, A.K.A., a transmission, in an electric vehicle, but it's not (typically) necessary.
- Throttle control. A well-programmed EV can give you precisely the response you ask of the throttle.
- No brake fade. Using energy regeneration by turning the electric motor into a generator can be used to slow down a vehicle, taking a lot of the work (and resulting heat, which causes fading) from the brakes.
- Battery packaging. Although they are heavy, batteries can be packaged in a number of different ways in a chassis. Flat and low, or higher, but more centralized, different approaches will yield different results. Internal combustion engines can be placed over the front axle, just ahead of the rear axle, or over the rear axle, but you can't really distribute an engine beneath the floorboards of a vehicle.
One feature not mentioned in the video, but which was raised by the channel in the comments beneath it is traction control. Electric drive allows for very precise management of wheel spin, which is important when the vehicle your driving also has gobs of instant torque.
