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.
