The Renault 4 is now available in the UK with a folding cloth roof, evoking the option that was available with the original 4 in the 1960s.

Launched almost a year after the standard electric crossover went on sale, the Plein Sud variant (which translates to 'Due South') commands a premium of £1500, being priced from £27,445 (including the full £3750 Electric Car Grant offered by the UK government).

While it isn't a true convertible, with its soft top opening similarly to a traditional glass sunroof, Renault claims its opening is wider (80x92cm) than those offered by rivals and it's therefore unique in its segment. 

While the Plein Sud is mechanically unchanged compared to the standard fixed-roof 4, using the same 148bhp front motor and 52kWh battery, the additional weight the roof mechanism brings, as well as the slight dent in aerodynamics caused by the roof, marginally lowers range from 245 to 242 miles.

Other technicals remain the same, including the 420-litre boot capacity and 8.2sec 0-62mph time.

The new variant introduces new safety features (now up to 28) to the 4, as it meets the EU's new GSR2.3 safety standard, which includes a driver fatigue monitoring camera and a new emergency stop system.

The cheapest Plein Sud comes in mid-rung Techno+ trim. This gets 18in diamond-cut alloys, keyless entry, dual-zone climate control, part-leatherette upholstery, a Google-powered 10in central touchscreen, wireless smartphone mirroring, a wireless phone charger, adaptive cruise control and hands-free park assist as standard.

At £29,445 (grant included), Iconic+ trim adds bespoke black wheels, a powered bootlid, heated front seats, a heated steering wheel, contrasting yellow interior trimmings and an enhanced suite of driver aids.

The 4 Plein Sud can be ordered from today by 'R-Pass' holders and from 14 May by everyone else.
