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.

The T03 has not been tested by Euro NCAP as of July 2026. Leapmotor's sibling model, the B10 (a larger SUV), achieved four stars in December 2025, but that result cannot be applied to the T03. There is no indication of when — or whether — the T03 will be tested.

The Dacia Spring was tested by Euro NCAP in 2021 and received one star out of five. That result related to the older model and previous-generation safety systems. The updated 2026 Spring has not been retested. It is not possible to say that the one-star result applies to the current car; equally, it is not possible to say it does not. Dacia has not announced a new NCAP test for the 2026 model as of July 2026.

The Spring did achieve five stars from Green NCAP in 2025 — testing environmental credentials rather than crash safety, but a meaningful result for its efficiency credentials.

Both cars come with a reasonable set of standard driver-assistance technology. The T03 includes six airbags, AEB, blind-spot detection, lane-keep assist, ACC, traffic sign recognition and a reversing camera. The Spring 2026 features similar safety technology — updated with new sensors for the 2026 model — but the specific calibration has not been independently validated in UK conditions.

Insurance group for the T03 has not been assigned. Insurance group for the Spring Expression 70 is group 1 (some of the cheapest insurance in the UK); the Extreme 100 group has not been confirmed in current sources.

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): zero in the first year for zero-emission vehicles, then £10 per year from the second year under the standard rate for EVs registered from 1 April 2025. The luxury VED supplement (£425/year) does not apply to either car — both cost well under £40,000.

For company car (BiK) purposes, both cars sit in the 2% BiK band for zero-emission vehicles (2025/26 and 2026/27 tax year). For a basic-rate taxpayer, the annual BiK tax on the T03 (P11D approximately £15,995) is roughly £64/year; on the Spring Extreme (P11D approximately £16,740) roughly £67/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.

Choose the Leapmotor T03 (£12,995) if: — You drive mainly in cities and suburbs and charge overnight at home — You want the most battery capacity and WLTP range at this price point — You do not rely on Apple CarPlay or Android Auto (or are willing to wait for OTA delivery) — You want a single fully-specified trim with no upgrade decisions to make — You are comfortable with Leapmotor's shorter UK dealer presence (79 sites, all Stellantis-backed)

Choose the Dacia Spring Extreme Electric 100 (~£12,990) if: — Boot space matters — the Spring's 308L is 46% larger than the T03's 210L — Wireless CarPlay and Android Auto are non-negotiable — You prefer faster rapid-charging top-ups on a road trip (29 min vs 53 min to 80%) — You want a rear wiper — relevant daily in the UK — You prefer the Renault/Dacia dealer network's wider reach and established history

Choose the Dacia Spring Expression Electric 70 (~£12,240) if: — You want the absolute lowest possible price for a new electric car — Daily driving does not exceed 60–70 miles and city speeds predominate — You can accept the lower 52 kW/70 hp motor and lack of wireless CarPlay

Neither car is right for buyers who regularly drive more than 100 miles a day, use motorway services for rapid charging, need Euro NCAP safety ratings, or want CarPlay on the T03 (no confirmed date). In those cases, the step up to the Citroen e-C3 (from around £21,000) or MG S5 EV (from £28,495) opens significantly better options.

A note on both grants: the LEAP-GRANT and Dacia Electric Car Grant are manufacturer commercial incentives with no guaranteed expiry. Confirm they remain in place at the time of ordering.
