Hr20-E. More drive less talk.
Highlander Racing’s second fully electric vehicle. Featuring an all new accumulator design and higher system voltage, iterated suspension and chassis with improved packaging, corner assemblies designed to minimize unsprung mass, and an Emrax 228 paired with a custom designed gearbox. HR20-E will deliver when it comes to race day.
Debuts June 2022 at Formula SAE Michigan
Corner Assembly
The corner assembly refers to what connects the wheel to the suspension and everything in between. This is comprised of the upright, wheel hub, brake system and wheel itself.
aerodynamics
HR20-E will have a full aerodynamic package featuring a front/rear wing, diffuser, and a drag reducing body - designed, manufactured, and tested in less than a year. Over 400 lbF of downforce at top speed.
steering system
A jointed system consisting of the steering wheel, bevel box and rack and pinion, this driver to vehicle interface is a critical part of racing.
Powertrain
This is what takes a 650 lbF body from 0 to 60 mph in under 4 seconds. Featuring a student designed two stage gear reduction system driven by an Emrax 228 100 kW electric motor. Pure awesome.
Accumulator
A complete redesign from HR19-E’s battery pack, the choice was made to use cylindrical over pouch Li-ion cells. Now at a higher system voltage, a robust and efficient cell packaging design will take the HR20-E to new (podium) heights.
Chassis
The primary load bearing structure of the vehicle and the only system to interface with all other subsystems - 20-E’s chassis was designed to maximize packaging efficiency while maintaining a high specific torsional stiffness.
Controls
Designing a custom battery management system, integrating a vehicle control unit, capturing and acting on data received from the vehicle during testing, creating interfaces for the driver — Controls has it covered.
SUspension
Translating all forces felt by the vehicle while maximizing traction to all four wheels. HR20-E’s iterated suspension design ensures a high degree of adjustability so that no stone is left unturned on test day.
