- James May bought one

Battery cars are heavy

We have all heard this a lot recently and it is part of the reason that some people like hydrogen as a fuel source.

Now I have touched on this subject before, but this article will be about the whole automotive package, rather than just the energy carrier.

It will also be a fairly short article as the numbers are pretty easy.

I tried to find a battery powered car that is similar to the Toyota Mirai that James May has recently bought. The Tesla Model 3 is, on wheelbase, 40 mm shorter, the Model S is 40 mm longer, and the Nissan Leaf is 220 mm shorter, so that counts that out.

On width, the Model 3 is 35 mm thinner, with the Model S being 79 mm wider.

So the Tesla Model 3 is pretty close, mechanically, in size.

So how does it compare to the 1,850 kg mass of the Mirai.

Depending on which model is chosen, it can range from 239 kg to 3 kg lighter. Yes, the Tesla weighs less.

I shall repeat that, the Tesla weighs less.

Just for completeness the Model S has a mass of 1,961 kg, 111 kg more than the Mirai, and my old Ford C-Max from 2007 is 1,391 kg.

  • this is why the argument of efficiency in EV does not work. how can a heavier car be more efficient than a light car? I don't know why some manufacturers are concerned about autonomy when they haven't resolve battery weight.

    • An ocean cargo ship is a lot heavier than a train, but uses less fuel per tonne of cargo for a set distance.

      The reason that EVs are more efficient than ICEs is that the efficiency is 3 to 4 time better.

      Mass only makes a difference during...

    • come on, still it needs more energy to accelerate a heavier object. stop and accelerate is the most common occurrences of a daily driven car. the only argument is that ICE idles on stationary, other than that situation, EV won't be more...
