Renault 4 E-Tech Plein Sud in Portugal: Price, Range and Specs
Published: 05/05/2026
Europe's cheapest electric convertible costs 37,290 euros
Spain has the official numbers: 36,850 euros for the Techno trim and 38,850 euros for the Iconic. France lists it at 36,300 euros. The Renault 4 E-Tech Plein Sud is the brand's new five-seat electric convertible, with a retractable canvas roof, and Renault claims it is the most affordable open-top on the continent. The Renault 4 E-Tech Plein Sud Portugal price is not yet officially confirmed, but the launch should land close to 37,000 euros, mirroring the Spanish line-up.
Plein Sud is not a separate car. It builds on the existing Renault 4 E-Tech 150 hp, with the same 110 kW motor, the same 52 kWh battery and the same 395 km WLTP range. Only the roof is new.
How the Renault 4 Plein Sud canvas roof works
A 92 cm by 80 cm opening slides electrically along the roofline. This is not a full convertible where the entire structure folds away — it's a large-scale fabric sunroof. The canvas folds in three sections, sits on a lightweight plastic frame, and was developed with Webasto and Haartz, two long-standing suppliers in the segment.
You can open it three ways: a button on the centre console, a command on the key fob, or a voice command through the Reno avatar in the infotainment system. The antenna has been moved to the rear window, and an integrated wind deflector keeps cabin turbulence in check at motorway speeds.
One detail matters for buyers wary of fabric-roof solutions: interior space is essentially untouched. Front headroom is 906 mm, rear headroom 813 mm — almost identical to the standard Renault 4. Five-seat capacity stays. Renault says the R4 E-Tech was engineered from day one to take this roof, and it shows.

For the segment, these are honest numbers. A 52 kWh battery covers urban duty and weekend trips to the beach or the Serra da Estrela comfortably — which is exactly where a car like this earns its keep. For non-stop Lisbon-Porto runs you'd want something larger, but that's not what the Plein Sud is selling.
Charging and 2026 updates for the Renault 4 E-Tech
Alongside the Plein Sud, Renault rolled the entire Renault 4 E-Tech into model year 2026. The most useful change is a new water-to-water heat exchanger that clearly improves DC charging in cold conditions. At 0 °C, a 15-80% top-up takes 50 minutes. At -20 °C, it takes one hour and ten minutes. The extreme figure is unlikely to apply to most of Portugal, but the cold-morning improvement is real for anyone living in the interior in January.
Driver assistance now lists 28 functions, including a driver-monitoring camera, emergency stop assist, and predictive eco-driving that reads the road ahead to manage regenerative braking. The package includes 2 GB of monthly connectivity data for three years.
Renault 4 Plein Sud Techno vs Iconic
The two trims are 2,000 euros apart in Spain, and that gap is likely to hold in Portugal. Techno is the entry level but already well kitted for daily use; Iconic adds premium materials, larger wheels and styling cues that lean harder into the retro look.
Worthwhile options to factor in:
- V2L adapter (AC power output from the car): 210 euros
- Google + Harman Kardon pack: 610 euros
- Metallic and two-tone paint: varies
If you want the closest experience to the original 1968 Renault 4L Plein Air — the open-top beach 4L this whole concept comes from — a well-specced Techno with a striking paint finish is the smart play.
What it should cost in Portugal
Without an official statement from Renault Portugal, this is an estimate. Spain charges 36,850 euros for the Techno and 38,850 euros for the Iconic. France charges 36,300 euros for the equivalent car. Renault's electric prices in Portugal have closely tracked Spain in recent years, with a small uplift, and full ISV exemption applies because pure EVs are exempt from Portugal's car registration tax.
Reasonable Portuguese pricing:
- Renault 4 Plein Sud Techno: around 37,000–37,500 euros
- Renault 4 Plein Sud Iconic: around 39,000–39,500 euros
Two more notes for buyers in Portugal. First, EVs remain ISV-exempt and pay only the minimum IUC (annual road tax), which makes ownership noticeably cheaper than a combustion equivalent. Second, if the Fundo Ambiental keeps its 2026 grant for private buyers of new EVs, there's another 4,000 euros to deduct from the final price, subject to that year's rules.
Frequently Asked Questions
Without an official statement from Renault Portugal, a reasonable estimate is around 37,000-37,500 euros for the Techno trim and 39,000-39,500 euros for the Iconic, aligned with Spain (36,850 and 38,850 euros). Pure EVs are exempt from ISV registration tax and pay only the minimum IUC, and if the Fundo Ambiental keeps its grant in 2026 there's an additional 4,000 euros to deduct from the final price.
Official WLTP range is 395 km, identical to the standard Renault 4 E-Tech 150 hp, with a 52 kWh battery and a 110 kW motor. In mixed urban and highway use, expect roughly 300-340 km, comfortably enough for daily duty and weekend trips to the beach or the Serra da Estrela. For non-stop Lisbon-Porto runs you'd want a larger battery, but that's not the Plein Sud's brief.
This isn't a full convertible — it's a large-scale fabric sunroof with a 92 cm by 80 cm opening that slides electrically along the roofline. The canvas folds in three sections, was developed with Webasto and Haartz, and opens via a centre console button, the key fob, or a voice command through the Reno avatar. Cabin space is essentially untouched: 906 mm of front headroom and 813 mm rear, almost identical to the standard Renault 4.
Order books opened between April and May 2026 in Spain and France. For Portugal, official pricing should land in June 2026, with first deliveries expected in the third quarter. It's worth watching Renault Portugal's announcements over the coming weeks.
The two share the AmpR Small platform, the 150 hp motor and the 52 kWh battery, but the Renault 5 E-Tech 150 hp starts at 27,900 euros in Portugal — clearly cheaper. The Renault 5 is the obvious choice for the most playful city car and icon-of-the-moment styling; only the R4 Plein Sud delivers the opening roof, more usable space and a mini-SUV stance. There is no convertible Renault 5, and the Plein Sud is unique in Europe under 40,000 euros in this format.
Renault 4 Plein Sud vs Renault 5: which to pick
This is the comparison every dealer will face. The two share the AmpR Small platform, motor and battery. The Renault 5 E-Tech 150 hp 52 kWh starts from 27,900 euros in Portugal in the equivalent trim — clearly cheaper than any R4 Plein Sud.
The choice comes down to this: if you want the more playful, pure city car with the icon-of-the-moment styling, the Renault 5 is the obvious answer. If you want more usable space, the slightly higher mini-SUV stance and — above all — a roof that opens, only the R4 Plein Sud delivers. There is no convertible Renault 5, and Renault hasn't suggested one is coming.
In practice, the Plein Sud is a niche-within-a-niche: a buyer who has already chosen the Renault 4 and is willing to spend 2,000–3,000 euros more for open-air driving. For that buyer, nothing else in Europe under 40,000 euros does the same job.
