New range-extender hybrid uses supercar tech for efficiency boost

Horse's D20 powertrain uses power-dense axial-flux electric motors to save space and boost efficiencyHorse Powertrain, a joint venture of Geely and the Renault Group, has revealed a new range-extender hybrid powertrain with an advanced axial-flux electric motor.
The pancake-shaped axial-flux design is much more compact and power-dense than the drum-like radial-flux design that's commonly used in today’s electric and hybrid cars. 
Horse claims its motor is 46% shorter than a
