New update from Pistonheads!

Collaboration just announced between Morgan and Frazer Nash for new EV3 powertrain. It will now use a 21kWh battery and 34.8kW (41.8kW peak) electric motor for the single rear wheel, with a 120-mile range. Morgan is suggesting that the new arrangement will bring the EV3's performance in line with the petrol-powered 3-Wheeler (0-60mph in six seconds)

Production now set to start Q3 next year which I suspect means Q1 2019 for me....

It might be quicker to build my own!
