Leapmotor T03 vs Dacia Spring (UK 2026): Britain's two cheapest electric cars compared

From July 2026, these are the two most affordable new cars sold in Britain — and they are both electric and both made in China. The Leapmotor T03 costs £12,995 on the road with Leapmotor's own £3,000 LEAP-GRANT. The Dacia Spring Extreme Electric 100 costs approximately £12,990 with Dacia's own £3,750 Electric Car Grant. Neither grant is a UK government scheme; both are manufacturer-funded commercial incentives.

Buyers often assume both are the same category of car. They are not. The T03 has a significantly larger battery (37.3 kWh vs 24.3 kWh) and a longer WLTP range (165 miles vs 140 miles). The Spring has a meaningfully larger boot (308L vs 210L), charges to 80% faster in real-world use (roughly 29 minutes vs 53 minutes), and on the Extreme trim offers wireless Apple CarPlay and Android Auto — a feature the T03 lacks entirely as of July 2026.

If you need more range per charge and charge at home overnight: the T03. If you need more boot space, wireless CarPlay, or faster rapid charging stops: the Spring Extreme. If cheapest-possible total price matters and you can live with the 70 hp motor: the Spring Expression at ~£12,240 is the lowest.

Both are city cars first. Neither is a long-distance motorway vehicle.

The battery size difference is the most important spec difference between the two cars. The T03's 37.3 kWh battery (36.0 kWh usable, LFP chemistry with CATL cells) is 50% larger than the Spring's 24.3 kWh battery (24.0 kWh usable, also LFP — the first LFP in any Renault Group car). Both use lithium iron phosphate chemistry, which means slower degradation over time and a reduced fire risk compared with NMC chemistry.

The official WLTP range is 165 miles for the T03 and 140 miles for the Spring Extreme. EV Database's real-world estimates paint a starker gap: approximately 135 miles combined for the T03 versus approximately 95 miles combined for the Spring Electric 100 — with the Spring dropping to around 70 miles in cold motorway conditions. UK press tests of the T03 found 115 miles in a UK winter and up to 144 miles on a mixed commute. No independent UK press test of the 2026 Spring was available at time of writing (July 2026) — EV Database estimates only.

For typical UK urban use — daily commutes under 40 miles, charged overnight at home — both batteries are workable. The T03's larger pack provides more buffer for cold days and unexpected detours. Neither car is practical for regular motorway long-haul.

On paper the T03 looks like the better charging car — 48 kW vs the Spring's 40 kW. In practice the Spring wins on rapid charging stops. Because its battery is 33% smaller, a 20–80% charge on the Spring takes approximately 29 minutes at 40 kW, compared with 53 minutes for the T03's 10–80% at 48 kW. If you are planning to use public rapid chargers for top-ups, the Spring spends less time plugged in at each stop.

For everyday home charging, the T03's larger pack means you are starting each morning with more range in reserve without any extra effort. Both cars charge on AC at 6.6 kW via a Type 2 socket — a full charge from empty takes about 6.5 hours on the T03 and about 4.5 hours on the Spring.

Neither car supports battery preconditioning before a charging stop, which means cold-weather charging performance is sub-optimal for both. Neither supports V2L (vehicle-to-load), V2H or V2G bidirectional charging.

Despite the Spring being only slightly longer (3,701mm vs T03's 3,620mm), it offers a significantly larger boot: 308L versus the T03's 210L with seats up. That is a real-world difference — the Spring takes a week's supermarket shop where the T03 requires more creativity. Both cars seat four; rear headroom and legroom are tight by any standard, as expected in A-segment city cars.

The T03 surprises reviewers with its panoramic sunroof — unusual at this price point and standard on all UK variants. The Spring's cabin is functional and plainly specified on Expression trim; the Extreme adds a 10.1-inch multimedia display with wireless CarPlay and Android Auto. This is the critical tech split. As of July 2026 the T03 has no CarPlay and no confirmed date for it; most UK T03 owners mount their phone using a separate holder, which works but requires an additional purchase.

The T03 has no rear wiper — noted by every UK reviewer as a meaningful disadvantage in British conditions. The Spring has a rear wiper on both trims.

Both cars have functional but not sophisticated interiors. Neither is trying to be luxurious. The T03's interior materials have drawn criticism from Chinese owners for quality at the Chinese price point (around £7,000–8,000 equivalent); at the UK price of £13,000 expectations differ, and UK press reviews have been more forgiving.

Both cars are made in China.

The T03 is built in Jinhua, Zhejiang by Leapmotor (零跑汽车), a Chinese EV specialist founded in 2015. Since 2023, Stellantis has held a 21% stake in Leapmotor and a 51% controlling stake in Leapmotor International (LPMI) — the joint venture that handles all sales outside China. The T03's UK warranty and service are backed by Stellantis's existing dealer network. Leapmotor reported its first-ever annual net profit in 2025 (approximately CN¥540 million, around £47 million).

The Dacia Spring is built in Shiyan, Hubei by eGT New Energy Automotive — a joint venture between Dongfeng, Renault, and Nissan. Dacia is a Romanian marque owned by the French Renault Group. Despite the Romanian heritage and French ownership, every Spring sold in the UK is manufactured in China. Dacia UK service and warranty are handled through the Renault UK dealer network, which is considerably larger and more established than Leapmotor's 79-site UK presence.

For brand survival risk: Dacia/Renault is a long-established European brand with deep dealer infrastructure. The risk of buyer stranding is low. Leapmotor is newer and its UK presence depends on the LPMI joint venture continuing; the Stellantis backing substantially reduces but does not eliminate that risk compared with a fully independent Chinese new entrant.

Both cars attract the same Vehicle Excise Duty (VED): £10 in the first year for a zero-emission car, then the £200 standard rate from the second year. The Expensive Car Supplement (£440 a year on top, for years two to six) does not apply to either — it starts at £50,000 for an electric car, and both cost a fraction of that.

For company car (BiK) purposes, both cars sit in the 4% zero-emission band for 2026/27 — it was 3% in 2025/26. For a basic-rate taxpayer, the annual BiK tax on the T03 (P11D approximately £15,995) is roughly £128/year; on the Spring Extreme (P11D approximately £16,740) roughly £134/year. Both represent exceptional salary-sacrifice value.

For pure running costs: both use LFP batteries and AC home charging at comparable rates. The T03's larger battery means a full overnight charge costs marginally more (roughly 40–50p more at a typical 25p/kWh home tariff), but the T03 also covers more distance per charge. Efficiency on the T03 is approximately 4.0 mi/kWh (mixed conditions); the Spring is slightly less efficient given its smaller battery and similar performance, at approximately 3.5–3.8 mi/kWh estimated.

Insurance: the Spring Expression 70's insurance group is expected to be among the lowest available (group 1). The T03 has not yet been assigned an insurance group (July 2026). If insurance cost is a key decision factor, this represents a material unknown for the T03.
