Renault is set to give its popular electric duo, the R4 and R5, a technical boost by introducing upgraded ‘Gen 2 Evo’ motors starting late 2026 or early 2027.
This update aims to enhance both efficiency and power output, ensuring the models remain competitive against a new wave of rivals.
Both the R5, which launched in 2024, and its crossover sibling, the R4 (pictured above), which followed in early 2025, currently utilise Renault’s second-generation externally excited-synchronous motors (EESM).
These are currently available in two configurations: the Urban Range (121bhp, 40kWh battery) and the Comfort Range (148bhp, 52kWh battery). These setups provide the R5 with up to 252 miles of range, while the R4 delivers 250 miles.
The upcoming enhancements draw directly from lessons learned during the development of third-generation drive units destined for the next-generation Scenic and Megane, expected in 2028.
Marianne Bataillon, Renault’s director of EV motor and battery development, confirmed that the primary focus of the Gen 2 Evo update is on improving the motor’s inverter and reducers. These modifications are specifically engineered to yield greater overall efficiency and higher power figures.
The Gen 2 Evo technology has already made its debut in the upcoming Renault Twingo, though its output is capped at 80bhp for that model due to its urban-centric design.
For the R4 and R5, this technological refresh is crucial for maintaining market parity. Newer competitors, such as the upcoming Volkswagen ID Polo and the Skoda Epiq, have set higher benchmarks in range, with the ID Polo offering up to 283 miles between charges.
By integrating the refined Gen 2 Evo hardware, Renault aims to bridge this gap, ensuring its small EV range remains a compelling option for buyers as the electric car segment continues to evolve rapidly.
