Lotus Evija

The project brief

The brief

In 2020, WAE supported a strategic technical partnership with Lotus with the companies sharing research and development into advanced propulsion technologies. At the heart of the Evija is an ultra-advanced all-electric powertrain, developed by WAE. The battery pack is mid-mounted immediately behind the two seats and supplies energy directly to four powerful e-motors. The highly efficient system is the lightest, most power dense, electric power package ever fitted to a road car

The work

  • Thermo-Fluid Design & Development, Extensive CFD work, 10 System Simulations
  • Active Rear Wing (including DRS), External Vehicle Aerodynamics, Hydraulic System
  • High-Voltage Cooling Systems
  • Cabin Comfort & HVAC Unit
  • Extensive Track Testing

1.4mw E-Drive (Motors/Transmission)

Most power-dense e-axles are only made possible by the level of integration; shared internal coolant circuits and use of the housing of the e-drives act as a structural bridge between the anti-vibration mounted transmissions

2000kw Battery

The world’s most power-dense battery offering 2000kW of peak power, ensuring sufficient, sustained power for world-beating lap times and dynamic road driving

High Performance – WAE BMS

WAE developed a uniquely ultra-light performance ISO26262 ASIL C compliant BMU to enable industry leading intelligence, resulting in a class-leading battery performance, data insights and safety

HV Charging 

Fastest charging vehicle with sustained charging at >350kW with a peak of 500kW

4wWheel Torque Vectoring

Motorsport derived vehcile control shifts torque both fore-aft and from side to side, eliminating the need for costly and heavy differnetials whilst ensuring optimal vehicle performance 

Adaptable – WAE VCM

WAE developed Vehicle Control Module, meeting ISO26262 and ASIL requirements. Ideally suited to high performance EV powertrain and vehicle systems

The outcome

Improved Vehicle Cooling

Improved On-Track Performance through Aerodynamic Gains

Improved Driver Comfort through HVAC Improvements

Wing Mirrors Changed to Cameras to Reduce Drag
