2026 ranking: the 6 most efficient electric SUV-B models, measured in kWh/100 km in city driving

The electric SUV-B segment has become the epicentre of real electrification in Spain. Cars between 4.10 and 4.35 metres long, a contained battery and one clear mission: getting around the city while spending as little as possible. And here, in the WLTP City cycle, is where the wheat is really separated from the chaff. A consumption of 13 kWh/100 km versus 16 kWh/100 km does not look like much on paper — in practice that is 30 extra kilometres a day from the same plug.

This ranking focuses exactly on that: the most efficient electric SUV-B models in the city, using official WLTP City figures, not combined ones. The difference matters.

Why does urban efficiency define the modern electric SUV-B?

In town, the combustion engine loses. The electric car, on the other hand, thrives: constant regeneration on every braking, zero consumption at traffic lights, torque available from a standstill. A well-designed electric SUV-B can drop below 14 kWh/100 km in the homologated urban cycle, something unthinkable on the motorway, where weight and frontal area penalise without mercy.

What does WLTP City measure compared with mixed consumption?

WLTP has four phases: Low, Medium, High and Extra High. The figure that almost all manufacturers publish is the combined one. But the Low + Medium phase — what we call consumption in kWh/100 km of the urban electric SUV — is the one that reflects real use for someone living in Madrid, Barcelona or Valencia. That is where we look.

The role of the heat pump, weight and aerodynamics

Three factors explain 80% of the differences. A heat pump can cut up to 2 kWh/100 km in winter compared with a traditional electric resistance heater. Weight affects every start and every regenerative braking event. And aerodynamics, although less critical in town, still bites above 50 km/h.

Ranking methodology

We have taken official WLTP City figures from each manufacturer for the most efficient version sold in Spain in 2026. Where the manufacturer does not publish a City breakdown, it is estimated from the combined cycle by applying the typical -8% factor that characterises the segment. All the models are actually on sale at domestic dealerships.

1. Hyundai Kona Electric — from 37,500 €

It tops the list with conviction. The second generation of the Kona Electric, with the 48.4 kWh variant, homologates around 10.7 kWh/100 km in WLTP City thanks to a very well-developed standard heat pump, a front end that is almost completely closed, and a thermal management system that works like clockwork in dense traffic. Regeneration via steering-wheel paddles allows well-calibrated one-pedal driving — in my opinion, the best in the segment.

2. Renault 4 E-Tech — from 29,900 €

The new Renault 4 E-Tech reinterprets the myth and does so with urban efficiency approaching 13.4 kWh/100 km WLTP City in the 40 kWh variant. The AmpR Small platform, shared with the R5, prioritises urban use: LFP battery, an optional heat pump that is highly recommended, and a weight held to 1,450 kg, which helps on every braking event. Surprisingly decent aerodynamics for such a square design.

3. Peugeot E-2008 — from 39,000 €

With the recent facelift and the 54 kWh battery, the E-2008 sits at around 13.8 kWh/100 km WLTP City. The e-CMP2 platform has gained converter efficiency, and the heat pump now comes as standard on the mid-range trims. That said, it weighs more than its French rivals — 1,590 kg — and this shows in repeated acceleration. Its strong point is a renewed i-Cockpit that makes the urban commute less monotonous.

4. Jeep Avenger Electric — from 38,000 €

It shares its base with the E-2008, yes, but Jeep tunes it differently. The Avenger Electric declares around 14.0 kWh/100 km WLTP City, helped by slightly lower weight (1,536 kg) and gear ratios designed for the city. The heat pump, optional here, is practically essential if the car is going to spend winter outdoors. It won the Car of the Year 2023 award and remains a rational purchase.

5. Kia EV3 — from 35,990 €

The EV3 stretches the segment slightly towards the compact SUV, but in its dimensions and approach it still plays in this category. It homologates around 11.8 kWh/100 km WLTP City in the 58.3 kWh Standard Range version — impressive for 4.30 m. Heat pump as standard, intelligent battery management which we already saw in the EV3 analysis, and a very polished i-Pedal regeneration system. It loses some ground to the Kona on weight (1,755 kg).

6. BYD Atto 2 — from 29,990 €

It closes the ranking with an interesting figure: 14.6 kWh/100 km WLTP City for an SUV-B that relies on an LFP Blade battery and an aggressive price. Efficiency is not on the level of the European models, but it is getting close. Its strong point is the price/equipment ratio and bidirectional V2L charging as standard. The heat pump is included and the thermal management behaves well in summer; in severe cold it still has some way to go.

Summary table: comparison of electric SUV-B models in Spain 2026

Score weighting urban efficiency, usable range, technology equipment and price.

What makes the Hyundai Kona Electric win?

It is no coincidence. The Kona uses a platform designed from scratch for efficiency, something we also saw in the IONIQ 5 vs EV6 showdown. Standard heat pump across all versions, a competitive drag coefficient for an SUV-B, and a regeneration system with four levels that recovers up to 20% of the energy on urban journeys. On paper it is the most efficient. In practice, it is too.

FAQ

Which is the most efficient electric SUV-B for city driving in Spain in 2026?
The Hyundai Kona Electric, with 13.1 kWh/100 km on the official WLTP City cycle, followed by the Renault 4 E-Tech (13.4) and the Peugeot E-2008 (13.8).

What is the difference between WLTP mixed consumption and WLTP City?
Mixed averages four phases (urban, suburban, extra-urban and motorway). WLTP City reflects only the urban Low and Medium phases, typically 8–12% lower than the mixed figure for electric cars because of regeneration.

Does the heat pump have a big effect on urban consumption?
Yes. It can mean 1.5–2 kWh/100 km less in winter compared with a traditional PTC resistance heater. In town, with frequent cold starts, it makes the difference between 300 and 350 km of real range.

Is it worth paying more for a Kona Electric over a Renault 4 E-Tech?
It depends on use. If you drive 15,000 km a year mainly in town, the extra 6,000 € takes a long time to pay back. The Renault 4 offers 95% of the efficiency for 84% of the price — in our view, the most rational purchase in the ranking.
