Good weight distribution in ICE cars is pretty exotic. Only fairly performance optimized ICE cars like a Porsche Cayman, BMW m3, and similar performance oriented cars get the ideal 50/50 distribution.

Changing that weight distribution is very expensive from a R&D perspective. Sometimes the battery is moved, or the engine is moved a few inches relative to the front axle. This is one of the reasons performance oriented cars are often rather large compared to their usable interior volumes.

Battery operated cars do have a weight penalty, but you can put that weight wherever you want. You could relatively trivially make a 50/50 distributor of significantly front or rear biased with no substantial R&D overhead or loss of efficiency.

For instance the Tesla model 3 not only has a very low center of gravity, but also a very low polar momentum. In an ice car that would require a mid engine design (like a Ferrari, Lamborghini, or the newest Corvette. While having an large usable volume, more like a bmw 5 series than a 3).

So basically weight distribution is easy to tweak with batteries, and even with the weight penalty have a substantial lead in efficiency.

I have already specifically mentioned that I am not talking about center of gravity or handling characteristics you'd find in a sports car. I have already written multiple comments about how you can put weight in a truck to add traction to the rear tires. I have already explained that electric vehicles are heavier but more efficient than ICE vehicles. You basically say similar things to what I said, and then come to the 100% wrong conclusion.

> So basically weight distribution is easy to tweak with batteries

No. You can do this when designing the car, but not afterwards. You want more weight in the regular pickup truck? Throw it in the back. You want less? Take it out. You can't take the batteries out of the electric vehicle. All my original comment said was you can add weight to the back of a pickup truck to improve traction on the rear axle. I didn't talk about center of gravity, or performance vehicles, or even mention that electric vehicles are heavier.

I am astounded by the amount of comments taking something I said, responding to it maybe tangentially and then concluding with "well that's why electric vehicles are better!" Let's just agree to disagree.
