Tesla Model Y vs Xpeng G6: Price, Range and Cost per Mile Compared

The Tesla Model Y is the better buy for most UK families: at the same £44,990 list price as the Xpeng G6 Long Range it goes 57 miles further on the WLTP cycle and costs about a fifth less per mile to charge. The G6 makes sense if you want the cheapest entry price, at £39,990, or the fastest peak charging speed.

The Xpeng G6 arrived in the UK as an open challenge to the Model Y, and the updated 2026 car sharpened that pitch with an 80.8 kWh battery and 800V charging. Both are mid-size electric SUVs with rear-wheel-drive and dual-motor versions. EV Compared has not driven either car, so this comparison uses published specifications and UK reviews, plus our own running-cost calculation.

How much do the Model Y and Xpeng G6 cost?

The G6 starts at £39,990 and the Model Y at £44,990, both list prices in November 2026. Xpeng prices come from Electrifying and Carwow; Tesla prices come from Carwow and our page on current Model Y and Model 3 prices.

	Model Y RWD	Model Y LR RWD	Xpeng G6 Standard Range	Xpeng G6 Long Range	Xpeng G6 Performance
List price (Nov 2026)	£44,990	£44,990	£39,990	£44,990	£49,990
WLTP range	314 miles	383 miles	292 miles	326 miles	316 miles

Tesla’s £44,990 price has been reported for both the entry Rear-Wheel Drive and the Long Range RWD, which EV Fleet World covered at its launch in February 2026. Our running-cost figures use the Long Range RWD, the closest match to the G6 Long Range at the same price.

Every G6 sits under the £50,000 expensive car supplement threshold, including the Performance at £49,990, which avoids the extra £440 a year by just £10. The Model Y Premium AWD and Performance are both listed above £50,000, so they pay it from the second year of tax.

Which costs less per mile to run?

The Model Y costs less per mile because it is more efficient. Tesla quotes 13.6 kWh per 100 km for the Long Range RWD on the WLTP cycle, while the G6 Long Range is rated at 17.5 kWh per 100 km (Autotijd). That means the G6 needs about 29 per cent more electricity to cover the same distance.

Method: WLTP kWh per 100 km × 1.609 ÷ 100 gives kWh per mile (0.219 for the Model Y, 0.282 for the G6), multiplied by the price per kWh.

Electricity price	Model Y LR RWD	Xpeng G6 Long Range	Gap per 10,000 miles
Home off-peak, 8p/kWh	1.75p a mile (£175)	2.25p a mile (£225)	£50
Intelligent Octopus Go, 6.5p/kWh	1.42p a mile (£142)	1.83p a mile (£183)	£41
Price cap, 26.32p/kWh	5.76p a mile (£576)	7.41p a mile (£741)	£165
Public rapid, 79p/kWh	17.29p a mile (£1,729)	22.25p a mile (£2,225)	£496
90% home at 8p, 10% rapid at 79p	3.31p a mile (£331)	4.25p a mile (£425)	£94

The 8p home rate is our standard methodology input; Intelligent Octopus Go now charges 6.5p, so we show that row too. The price cap figure is 26.32p/kWh for October to December 2026 (Energy Made Easy), and the 79p rapid price is Zapmap’s September 2026 average (Zapmap).

For a driver who charges at home overnight, the difference is small, about £50 a year at 10,000 miles. It matters more if you rely on public rapid chargers, where the G6 costs roughly £500 more over the same distance. Our guide to the cost of charging a Tesla breaks down home and public rates in more detail.

These are WLTP-based figures, and both cars use more in real driving. Carwow recorded 3.3 miles per kWh in its Model Y test, and Electrifying saw about 2.3 miles per kWh from a G6 Performance on winter motorway runs (Electrifying review). Those were different versions in different conditions, so they are not a fair head-to-head, but neither suggests the efficiency gap closes.

Which has more range?

The Model Y Long Range RWD has more range, at 383 miles WLTP against 326 miles for the G6 Long Range. The G6 Long Range carries an 80 kWh usable battery, so its shorter range comes down to higher consumption rather than a smaller pack.

At entry level the gap narrows. The Model Y Rear-Wheel Drive is rated at 314 miles (Auto Express) and the G6 Standard Range at 292 miles, a difference of 22 miles, though the Xpeng is £5,000 cheaper. Electrifying found real-world G6 range disappointing in winter, at just over 180 miles on motorway trips in the Performance, and expects about 250 miles in summer.

Which charges faster?

The G6 charges faster on paper. Its 800V system peaks at up to 451 kW on the Long Range and Performance and 382 kW on the Standard Range, and Xpeng claims 10 to 80 per cent in 12 minutes on a suitably powerful charger. Electrifying’s reviewer estimated 15 to 20 minutes in practice and noted the car still charged quickly on a 150 kW unit in cold weather.

The Model Y Long Range peaks at 250 kW and Tesla says it adds 173 miles in 15 minutes; the entry Model Y peaks at 175 kW.

The Tesla’s edge is the network. Zapmap counted 2,774 Tesla chargers at 447 UK locations at the end of September 2026 (Zapmap), with more than half open to other EVs. The G6 can use those open sites, as our guide to using a Supercharger in a non-Tesla explains, but Model Y owners get every site plus automatic battery preconditioning on the way. See Tesla Supercharger prices for what each driver pays.

Which has more boot space?

The Model Y has much more boot space: 854 litres with the rear seats up and 2,118 litres folded, plus an 88-litre front boot, according to Auto Express. The G6 offers 571 litres, rising to 1,374 litres with the seats down, and a shallow front boot. Electrifying describes the G6 boot floor as deep and wide enough for a double buggy, but the Tesla carries roughly 280 litres more with the seats in place.

Which is cheaper as a company car?

They pay the same at the same price, because both attract 4% benefit-in-kind in 2026/27. At £44,990, the Model Y and G6 Long Range each have a taxable benefit of £1,799.60 a year, which costs a 40% taxpayer about £60 a month and a 20% taxpayer about £30. The G6 Standard Range at £39,990 brings that down to about £53 and £27 a month. Our Tesla company car tax guide covers salary sacrifice and every Tesla version.

What about warranty and the ownership experience?

Xpeng covers the G6 for 5 years or 75,000 miles, with 8 years or 100,000 miles on the battery, according to Electrifying. The G6 is sold through a UK dealer network, while Tesla sells direct online and services cars through its own centres and mobile technicians.

Electrifying scored the G6 6 out of 10, criticising its ride over potholes, touchscreen-only controls (the mirrors are adjusted through the screen) and poor rear visibility, and warned that depreciation could be steep for a brand new to the UK. The Model Y also relies on a single central screen, so neither car suits buyers who want physical buttons.

Who should buy which?

Buy the Tesla Model Y if:

• You want the most range and lowest running costs for £44,990
• You do regular long trips and want full access to the Supercharger network
• You need the biggest boot of the two

Buy the Xpeng G6 if:

• You want to spend under £40,000; the Standard Range is £5,000 cheaper than any Model Y
• You charge mostly at home, where the per-mile gap is only about £50 a year at 10,000 miles
• You want a 4.1-second 0 to 62 mph time for under £50,000 (the Performance)
