Reading the diatribe something isn't right, removing 240 kg of engine and gearbox from the front and adding 136 kg to the rear (four 130 amp hour batteries at 34 kg each) may compromise the handling and braking and accelerate the rear body sag. I think I'd put the batteries under the bonnet.
Having dispensed with the motor which I use to slow my car down I think I’d want regenerative braking, or an anchor, to assist the abysmal brakes, his words not mine.
I thought my Seven produced 13 bhp at 3500 rpm to give a top speed of 54 mph from 747 cc, before I bored it out to +0.040”. So the 10 hp (7.6 Kw) 2800 rpm motor performance will be disappointing and want 152 amps at 50 volts.
I'm interested because the electric option has crossed my mind as has fitting a modern engine of similar power to shut the green lobby up who think our cars are polluters. I stress it is just a thought as I find the big end jet lubrication system and the thermo syphon cooling system wonderfully simple and proven over 90 odd years. The engine starts first go, even in winter, although with the Zenith 22FZB does require nursing till the engine has warmed up whilst the car is snug even in winter. That’s all part of running a Seven including windows misting up in the autumn rain.
