Justy research

To get some scope on the requirements a little research on the Subaru Justy will help. It was built with 2 engines.
  • 1 liter = 47 hp @ 5000 rpm
  • 1.2 liter = 66 hp @ 5200 rpm
ICE and Electric motors do not have the same HP ratings but there are many references that suggest a 3-4 X relationship. A 72 V system at 100 amps and .85 % efficiency would be about 8.2 HP. At 96V 10.9 HP and 120 V 13.6 HP. With a peak of 400 amps they would be 32.8 HP, 43.6 HP and 54.6.

So, a 72V system would be a little under powered compared to the original engine and a 120V setup would be a little over powered. More modern ICE engines have higher HP ratings for the same displacement.
