The 400 Wh/kg level would be 54% higher than roughly 260 Wh/kg that Tesla is using today.
EVs would not weigh that much then, even when having huge battery packs:
75 kWh battery at 400 Wh/kg: 188 kg of cells (compared to 288 kg now)
100 kWh battery at 400 Wh/kg: 250 kg of cells (compared to 384 kg now)
150 kWh battery at 400 Wh/kg: 375 kg of cells (compared to 577 kg now)
200 kWh battery at 400 Wh/kg: 500 kg of cells (compared to 770 kg now)

Lightweight battery packs = better performing and lower cost (other things being equal)

Excellent news! This got me properly excited about a true lightweight sport EV, possibly the first proper ///M EV?
A bit of Googling indicates that a B58 inline-6 weighs about 140 kg, and the accompanying ZF-8 another 90 kg for comparison. In
antzcrashing 's chart, this is roughly equivalent to a 100 KWh battery pack, which Google tells me is around 130 HP. But that's KW, not KWh so am I missing something here?
So not quite there yet but love the progress in such a short period of time! We might be on target to see something like this in 7-10 years!
