MG IM6 review (UK): 396 kW charging, 388 miles of range — and the Chinese premium car hiding under the badge

The MG IM6 is not what most UK buyers think it is. It is not a high-end version of the MG4 or ZS EV. It is the Chinese premium car known in China as the 智己LS6 (IM LS6) — engineered by IM Motors, a separate SAIC sub-brand created to compete with Tesla, NIO, and ZEEKR in the ¥200,000–300,000 bracket. IM Motors' founding partners include Alibaba and Zhangjiang Hi-Tech Park.

SAIC has zero IM Motors brand equity outside China, so the IM6 arrives wearing MG badges and is sold through MG's ~150 UK dealers. The car carries IM logos on the body but is marketed jointly as MG IM6. The result: UK buyers see 'MG' and assume a familiar brand, when they are actually buying into a separate premium programme.

The confusion matters in a specific way: when UK journalists write about the 'solid-state IM,' they are talking about the IM L6 sedan (sold in the UK as the MG IM5). The IM6 SUV uses conventional NMC chemistry. Not the same car. Not the same battery.

SAIC Motor (上汽集团) is the parent. It is Shanghai government state-owned, publicly traded (SHA: 600104), Fortune 500 company, and the force behind VW and GM's China joint ventures. SAIC has sold cars in the UK since 2011 under the MG badge and currently operates around 150 UK dealers. This is not a start-up: the service infrastructure exists.

IM Motors itself has delivered more than 100,000 IM LS6, LS7, and L6 units in China since 2023, with growth accelerating through 2025 as the EREV (range-extended) version joined the line-up. The 2026 Chinese sales trajectory remains strong. For a UK buyer this matters: the factory is not shutting down, and SAIC's UK commitment looks long-term.

The risk caveat: UK owner experience with MG aftersales has attracted real criticism — see the reliability section below. The 7-year warranty is only as valuable as the organisation prepared to honour it.

Three trims. All carry a 100 kWh NMC battery, 800V architecture, and 4-wheel steering as standard.

The Long Range (£48,495, RWD, 402 hp) does 388 miles on the WLTP cycle — more than any Tesla Model Y, more than any Hyundai or Kia, and 76 miles more than the BYD Sealion 7 at a similar price. The Performance and Launch Edition (£51,495/£53,495, AWD, 742 hp) drop to 313 miles but hit 62 mph in 3.5 seconds.

The charging headline: 396 kW peak DC, 10–80% in 17 minutes at a 350 kW+ charger. That is faster than any Tesla, any Hyundai E-GMP car, any Kia, or any VW Group model on UK sale at any price. Whether you will find a 350 kW charger on your regular route is a fair question — Gridserve and Osprey have some — but when you do, the IM6 fills faster than everything else.

Four-wheel steering is standard on all trims, shrinking the turning circle to 10.18 metres — less than a Golf — and adding motorway lane-change stability. This is a genuine rarity at this price; Kia only fits 4WS on the EV6 GT.

Prices rose by around £500 from the September 2025 launch by July 2026. Carwow discounts in the £4,000–6,000 range have been reported, though these fluctuate. Affinity pricing is reportedly higher still.

The MG IM6 received a five-star Euro NCAP rating in 2025. Adult occupant protection scored 90%, child occupant 85%, vulnerable road users 83%, and safety assist 87%. These are strong across-the-board results — the safety assist score, in particular, reflects a well-tuned ADAS package that Euro NCAP judged positively for European road use.

UK reviewers note the systems can still feel intrusive — warning alerts are set conservatively — but they are broadly well-calibrated for British conditions.

MG quotes a 7-year / 80,000-mile vehicle warranty on the IM6. All UK reviewers — including Electrifying.com's July 2026 test — confirm this figure. It matches the MG ZS EV and MG S5 EV, and is as generous as Kia's warranty, longer than Tesla's (4 years), and meaningfully better than most European rivals.

One important note: earlier reports cited a separate 8-year / 100,000-mile battery warranty. UK sources — including Electrifying.com — consistently quote the 7-year / 80,000-mile figure for both vehicle and battery. The 8-year / 100,000-mile battery term appears in Australian market reports, but has not been confirmed for the UK specification. If battery warranty terms matter to your decision, verify directly with MG UK or im.mg.co.uk before purchase.

In China the IM LS6 is a genuine premium contender, priced at approximately ¥213,000–285,000 (£23,000–£31,000 at current exchange). Chinese buyers pay roughly half what UK buyers pay — the premium reflects tariffs, homologation, right-hand-drive conversion, and UK dealer margin.

Sales trajectory is strong: 22,883 deliveries in the final quarter of 2023, 36,530 EV units in 2024, and 46,369 in 2025 (including 12,957 of the EREV variant launched September 2025). Cumulative deliveries passed 100,000 by January 2026.

Owner sentiment is more complicated. The 车质网 (12365auto) quality-complaint platform shows a satisfaction score of just 2.1 out of 5.0 — significantly below BYD Seal (87/100) and below the broader premium EV segment average. Common complaint themes across the LS6's model years: paint and body bubbling, ADAS camera fogging in humid conditions, air-conditioning evaporator malfunction (white powder from vents), premature tyre wear, and infotainment glitches. SAIC's manufacturer response rate of 95.2% indicates the company engages with complaints — but the root causes recur across model years.

The camera fogging complaint is worth flagging specifically for UK buyers: British winters combine high ambient humidity with wide temperature swings, which are exactly the conditions that trigger condensation in optical sensors. This is not a confirmed issue on UK-spec cars, but it is a known pattern on Chinese-spec cars with similar hardware.

The 汽车之家 (Autohome) owner score is more positive at around 4.1/5.0 for the 2024–2025 facelift — the September 2024 'Lizard Digital Chassis' update (integrating rear-wheel steering, air suspension, and CDC dampers) received genuinely strong technical reviews in China, with improvements over the pre-facelift car noted by several credible Chinese automotive journalists.

The IM LS6 that Chinese buyers order is a more technologically advanced car than the MG IM6 that arrives in the UK. The gaps are significant — and for buyers who care about smart technology, they matter.

The biggest gap is compute and sensor hardware. Chinese LS6 buyers get NVIDIA Drive Orin-X (254 TOPS) as standard, with Drive Thor-U (700 TOPS) as an option on higher trims. Most Chinese trims also include one LiDAR unit (96-line or 520-line). This hardware is designed for highway Navigate-on-Autopilot and eventual city NOA — the kind of assisted driving that lets you enter a motorway junction and have the car take over until your exit. The UK IM6's ADAS system uses cameras and radar — entirely conventional, competent Level 2. No LiDAR. No high-TOPS compute. No path to city NOA via OTA update, ever.

Other notable Chinese-only features: a 15.6-inch passenger entertainment screen, a zero-gravity front passenger seat, rear seat ventilation and massage, yoke steering wheel option, 256-colour ISC colour-changing tail lights, vehicle fridge, and an EREV powertrain option with up to 1,500 km combined range.

On the battery, Chinese buyers get a menu: LFP options from 52 kWh upwards, NMC options, and the EREV system. UK buyers get one choice: 100 kWh NMC. There is no EREV option for the UK.

The lifetime battery warranty that first owners get in China (with a ≤30,000 km/year cap) has become a standard marketing point. UK buyers get a fixed-term warranty instead — see the warranty section for the precise UK terms.

The MG IM6 has been on UK sale since September 2025 — the UK fleet is small and early. There is not yet enough data for a statistically meaningful reliability verdict. What exists is:

One documented case on the mgevs.com forum (April 2026) describes a Launch Edition owner whose car suffered a cascade of 17 fault codes — including a drive motor fault — after just 13 days and 4,500 miles of ownership. The car spent nine and a half weeks off-road. The root cause was identified as 12V battery drain cascading into multiple ECU failures; the repair required a new 12V battery, two ECUs, a telematics module, and multiple firmware flashes (several of which failed and required dealer attendance). MG UK's customer service response was rated as very dissatisfied by the owner.

The same owner noted that the IM6's 12V system does not charge when the high-voltage battery drops below 20% — a design sensitivity that can cause 12V drain under certain usage patterns.

This is one account. It may not be representative. The owner remained positive about the car itself ('excellent build quality, fast, comfortable') but strongly negative about the aftersales experience. The broader MG ZS EV and S5 EV track record on Trustpilot shows similar aftersales frustrations across the MG UK network — this is not an IM6-specific phenomenon.

For a premium £48,000+ car, a potential nine-week wait for resolution would be a serious inconvenience. Buyers considering the IM6 should factor in whether they have alternative transport and a realistic expectation of UK aftersales responsiveness.

The most recent comprehensive review is Electrifying.com's Ginny Buckley (3 July 2026), who gave the car a 7/10. The praise is consistent across all major UK reviews: the charging speed is genuinely impressive, the range outclasses most rivals, the cabin equipment is generous for the price (20-speaker audio, 26.3-inch panoramic display, heated and ventilated seats all round, double-layer acoustic glass), and the four-wheel steering genuinely reduces the urban effort of manoeuvring a near-5-metre SUV.

The criticism is equally consistent: the ride — particularly on the Long Range and Performance trims without air suspension — transmits too much noise and vibration. Electrifying's Buckley describes it as bumping and shuddering over urban roads. Almost all vehicle controls are on the touchscreen, with no physical climate or drive-mode selectors, which several reviewers describe as 'infuriating.' Efficiency is lower than the range figures imply — at around 2.9 miles per kWh — making the car heavier on electricity than a Model Y or EV6 in real use.

The Launch Edition's air suspension partially addresses the ride criticism, but adds £5,000 to the bill.

Residual values are completely unknown — there is no UK used-market history for the IM6. Buyers on PCP or those who plan to change cars within three years carry meaningful residual risk. Leasing transfers that risk to the leasing company.

At £48,495, the MG IM6 Long Range offers something genuinely difficult to beat on two specific metrics: 396 kW charging (17 minutes 10–80%) and 388 miles of WLTP range. Add four-wheel steering, a 20-speaker sound system, laminated acoustic glass, and a heated and ventilated back row as standard, and the spec-per-pound challenges everything in the segment.

The hardware is real. The technology is not vaporware. SAIC is not going away. On paper this is compelling.

Where caution is needed: the Chinese quality data (2.1/5.0 on 车质网, with recurrent paint, AC, and sensor issues) is a flag that cannot be waved away. The UK reliability sample is too small to confirm or deny the pattern, but one documented case of a catastrophic early failure with a poor aftersales response is a data point worth holding. The warranty terms need verifying directly for battery cover. Residual values are completely unknown. The ADAS ceiling is permanently lower than the Chinese car, with no upgrade path.

For salary-sacrifice buyers, the low 5% BiK rate and HMRC-recognised status make the IM6 genuinely attractive. For private buyers — particularly on PCP — the residual value uncertainty demands scrutiny before signing.

**Who it's for:** Long-distance drivers who regularly use rapid chargers, tech-comfortable buyers who do not miss physical controls, and salary-sacrifice drivers who can lease out the residual risk. **Less suited to:** buyers who prioritise driving dynamics, need V2L, or plan to sell within three years.
