They claim &quot;1 MW&quot; of power is supplied to the motors with batteries and a 300bhp engine but since 1 bhp =(roughly) 0.75 KW the batteries would need to supply 775KW the power and the combustion engine would not be able to keep the batteries charged sufficiently.<p>I&#x27;m not an expert on car power systems but this doesn&#x27;t appear to be feasible.
