- **Target price**: £25,000

## Why this model

⚠️ Limited UK data — Xpeng only arrived in the UK in late 2024/early 2025, so we have fewer MOT tests and less resale history than established brands. The Xpeng G6 is a sleek, modern electric SUV coupe that offers impressive technology and fast charging thanks to its 800V architecture. It's a strong contender for those looking for a high-tech EV with good range, but be aware of its newness to the market. Xpeng's global scale as part of a rapidly growing Chinese EV market leader supports future parts supply and service network growth.

## What you should pay

The Xpeng G6 is very new to the UK market, with initial deliveries starting late 2024/early 2025. This means any 2026 models on the used market will be nearly-new. Based on the broader used EV market trends and the rapid depreciation seen in new brands, we estimate a 2026 mid-trim G6 with low mileage to be around £25,000. However, due to limited data, expect a wider price range of £20,000-£30,000. This price reflects a significant initial drop from new, making it an interesting proposition for early adopters. The 66kWh liquid-cooled battery with active thermal management is a good sign for longevity, with expected degradation around 1.8% per year.

## Which trim to buy

The Long Range RWD trim offers a great balance, giving you the excellent 304-mile WLTP range (around 230-250 real-world miles) without the extra cost and complexity of the AWD system. It's still plenty powerful for UK roads and benefits from the same fast-charging capabilities, making it the sweet spot for most buyers.

## What to check before you buy

- Limited long-term UK data means potential unknown issues
- Possible software quirks as the brand establishes itself
- Limited established service network compared to older brands

## Running costs

Electric cars are cheap to run, especially if you charge at home. Using a standard rate (Ofgem cap 24.5p/kWh), you're looking at about 6.8p/mile, or around £682 a year for 10,000 miles. If you get a smart EV tariff like Octopus Go or Intelligent Octopus (around 9p/kWh overnight), that drops to about 2.5p/mile, costing only £251 a year for 10,000 miles – a saving of over £400! Road tax is free until April 2025, then it's £195/year. Insurance costs will vary, but expect it to be moderate to high for a new, high-tech EV.

## Key stats

- **Fuel Type**: Electric
- **Horsepower**: 286-470 hp
- **Mpg**: N/A (Electric)
- **Reliability Score**: Too new for comprehensive UK data
- **Safety Rating**: No Euro NCAP rating yet

## Trim comparison

| Trim | Price new | Price used | Key features |
| --- | --- | --- | --- |
| Standard Range RWD | £40,000 | £22,000 | 66kWh battery; 286 hp RWD; 304 miles WLTP range |
| Long Range RWD | £45,000 | £25,000 | 66kWh battery; 286 hp RWD; 304 miles WLTP range |
| Long Range AWD | £50,000 | £28,000 | 66kWh battery; 470 hp AWD; 280 miles WLTP range |

## Depreciation forecast

| Year | Estimated value | Retention |
| --- | --- | --- |
| 2026 | £25,000 | 100% |
| 2027 | £21,000 | 84% |
| 2028 | £18,000 | 72% |
| 2029 | £15,500 | 62% |
| 2030 | £13,500 | 54% |

Buying a 2026 model means you're getting a nearly-new car that has already taken a significant initial depreciation hit from its original new price. While it will continue to depreciate, the steepest drop has likely occurred, offering good value for an early adopter of this new technology and brand.

Total value lost since new: 46%.
