    So how many times will they do that before they crap out? I raced my Hemi for 4 years, and drove it on the street as well. It lasted another 4 years before I finally sold it to buy another car. I did overhaul it twice, mainly to upgrade the crank and replace rings, timing chain, and stuff. I'm betting it didn't cost as much as it does to replace an EV engine and battery. Plus it sounded a lot better, too.

    Not many until the technology improves. The test vehicle is a scaled down version of a F-1 car.

    EV maintenance is much cheaper than for ICs. There are less moving parts.
