REEV 4.0 is an improvement on the existing platform, not a replacement — six changes, built on what three editions taught us, aimed at deeper industry relevance and a sharper focus on software.
The electric motor is the sole source of propulsion in a REEV vehicle. The ICE range extender never drives the wheels directly — its only job is to spin a generator and top up the battery packs. This keeps the drivetrain electric-first while still using a small combustion engine to extend range beyond what the battery alone could deliver.
A standardized engine spec and a single motor size replace the bespoke generators teams used to design from scratch. Standardizing these two components widens access for new teams and removes a major source of ambiguity in scoring and safety scrutiny.
Two battery packs per vehicle switch under Open VCU software control, activating automatically once the active pack drops to roughly 20% state of charge. Teams design the switching and thermal strategy in software rather than in bespoke wiring harnesses.
With hardware now standardized across teams, REEV 4.0 shifts the competitive edge to control strategy: energy management logic, range-extender activation thresholds, and drivability tuning written on top of an open vehicle control unit.
Every subsystem — battery, charging, powertrain, thermal, software — is mentored by a named industry SME through the season, drawn from the same companies whose engineers already build vehicles professionally.
