For the Lotus Evora 414E Hybrid, Lotus Engineering has developed a highly efficient, high performance drivetrain system consisting of twin motors each limited to providing 152 kW (207 PS/204 hp) of power and 400 Nm (295 lbft) of torque to each wheel via independent, single speed, reduction transmissions integrated into a single housing, enabling torque vectoring dynamic control of the vehicle.

The range extended electric drive of the Evora 414E Hybrid consists of two electric motors driving each of the rear wheels independently via single speed geartrain. Additional range is provided by the Lotus Range Extender engine, an optimized 1.2 liter, three-cylinder engine, providing 35 kW (48 PS/47 hp) of power at 3,500 rpm via the integrated electrical generator.

The vehicle energy storage system is made up of the latest Lithium Polymer battery chemistry with over 100 kW discharge capability. The battery pack provides 17 kWH energy storage capacity. All the operation and management of the range extender engine, the power management of the batteries and motor control are controlled by Lotus’ electronic control units and software systems.

To enhance driver involvement, it is the incorporation of HALOsonic Internal and External Electronic Sound Synthesis technologies from Lotus and Harman International. This provides the Evora 414E Hybrid with sound contouring within the cabin and improves pedestrian safety outside the vehicle.
