How to find these values on your Renault

Wh/mi or Wh/km

On the OpenR Link or Easy Link display, navigate to "Driving" → "Energy" or "Trip Computer". Average consumption in Wh/km or Wh/mi is displayed in the trip data. On Mégane E-Tech, swipe to the energy history card.

Estimated Range

Estimated range is shown on the instrument cluster behind the steering wheel and in the Energy section of the central display.

Battery Percentage

Battery percentage is displayed on the instrument cluster next to the battery gauge and on the home screen of the central display.

About the Renault 4 E-Tech

The Renault 4 E-Tech is a charming modern reinterpretation of the iconic R4, reimagined as a compact electric crossover. Built on the same AmpR Small platform as the Renault 5 E-Tech, it offers a taller, more rugged body style with extra ground clearance and a more practical boot.

Two battery options are available: a 40 kWh LFP unit for shorter-range urban use and a 52 kWh NMC pack that delivers up to 247 miles on the WLTP cycle. The 110 kW motor provides adequate performance for a city-focused car, with 0-62 mph in 7.9 seconds. DC charging peaks at 100 kW, giving a 10-80% top-up in around 30 minutes.

Renault has leaned heavily into the retro aesthetic, with design cues nodding to the original 1961 R4 while keeping everything thoroughly modern underneath. The result is an EV with genuine personality — something many rivals in this segment lack. Pricing undercuts the VW ID.3 and makes a strong value case for small electric SUV buyers.

What the press thinks

Press reaction has been overwhelmingly warm, with reviewers charmed by the R4's retro styling, competitive pricing, and cheerful driving character. Range is adequate rather than class-leading, and charging speed is modest, but the overall package is seen as one of the most appealing small electric crossovers available.
