Tesla Model 3 vs Xpeng P7+: UK Cost per Mile, Price and Range

The Tesla Model 3 is the cheaper car to run and the only one of the two you can price in the UK today. The Xpeng P7+ is the bigger, better-equipped and much faster-charging car, so it suits drivers who rapid charge often, if its UK price lands close to the Model 3’s.

The P7+ is a large electric fastback that Xpeng has lined up against the Model 3. It is due in the UK later in 2026 through International Motors, the company that also handles GWM, Isuzu and Subaru, according to Electrifying. This comparison uses the German specification and official figures, because UK prices and final UK figures have not been published. EV Compared has not driven either car.

How much do the Model 3 and Xpeng P7+ cost?

The Model 3 costs from £37,990 for the Standard and £44,990 for the Premium Long Range RWD in November 2026, based on the UK cash prices tracked by EV Industry News. The Long Range AWD is £49,990 and the Performance £59,990. Our Model 3 and Model Y price guide covers the full line-up.

Xpeng has not announced a UK price for the P7+. In Germany it costs from €46,600 for the Standard Range, €49,600 for the Long Range and €53,600 for the AWD Performance (electrive). Electrifying has estimated a UK start of around £45,000, but that is its own estimate, not an Xpeng figure.

The UK price matters for tax. Electric cars listed above £50,000 pay the expensive car supplement of £440 a year, and the Model 3 Premium Long Range RWD sits well under that line. If the P7+ Performance comes in above £50,000, it will pay it.

Which is cheaper per mile, the Model 3 or the P7+?

The Model 3 is cheaper per mile. On official WLTP figures, the Model 3 Premium Long Range RWD uses 12.5 kWh per 100 km on 18-inch wheels (InsideEVs Germany), while Xpeng quotes 15.2 kWh for the P7+ Standard Range and 16.4 kWh for the Long Range (Xpeng). That makes the P7+ Long Range about 31 per cent thirstier in the lab.

We turned those figures into a cost per mile at three prices: 8p/kWh on a smart off-peak tariff such as Intelligent Octopus Go, the 26.32p/kWh price cap for October to December 2026, and the 79p/kWh average public rapid price from Zapmap for September 2026.

Method: kWh per 100 km ÷ 62.14 = kWh per mile; × price per kWh = cost per mile; × 10,000 for a year’s driving.

Electricity price	Model 3 Premium LR RWD	P7+ Standard Range	P7+ Long Range
8p (home, off-peak)	1.61p a mile (£161 per 10,000 miles)	1.96p (£196)	2.11p (£211)
26.32p (price cap)	5.29p (£529)	6.44p (£644)	6.95p (£695)
79p (public rapid)	15.89p (£1,589)	19.32p (£1,932)	20.85p (£2,085)

On a smart tariff the difference between the two Long Range cars is about £50 every 10,000 miles, which is small next to a likely difference in purchase price. It grows to about £165 at the price cap and £496 if every mile came from public rapid chargers. Tesla owners pay their own Supercharger rates rather than the 79p average; Zapmap lists 69p/kWh at 150 to 400 kW Tesla sites, which would bring the Model 3 to about 13.9p a mile. Our guide to the cost of charging a Tesla breaks that down by tariff.

Do real-world tests change the picture?

They narrow it, but the tests are not like for like. InsideEVs Germany measured the P7+ Long Range at 12.8 kWh per 100 km in mostly urban driving, about 16 kWh at 110 to 130 km/h and about 21 kWh above 140 km/h (InsideEVs). At UK motorway speeds, 16 kWh is about 3.9 miles per kWh, or 2.06p a mile at 8p.

Auto Express recorded 4.4 miles per kWh in the Model 3 Standard on a mixed rural and motorway route, which is 1.82p a mile at 8p. Those were different cars on different routes, so treat them as a guide. They suggest the gap in everyday driving is smaller than the WLTP figures imply, but nothing yet shows the P7+ beating the Model 3 on efficiency.

Which has more range?

The Model 3 Premium Long Range RWD goes further, at 466 miles WLTP against 530 km, about 329 miles, for the P7+ Long Range. At the cheaper end, the Model 3 Standard’s 332 miles beats the P7+ Standard Range’s 455 km, about 283 miles.

Electrifying reports UK claims of up to 341 miles for the rear-wheel-drive P7+ and 311 miles for the AWD, so the final UK figures may differ slightly from the German ones. Either way, the Model 3 Long Range has a lead of well over 100 miles on paper, because it pairs a bigger battery with lower consumption.

Which charges faster?

The P7+ charges much faster. It uses an 800-volt system and LFP cells, with a 446 kW peak on the Long Range and a claimed 12 minutes from 10 to 80 per cent. InsideEVs added about 38 kWh in seven minutes on a 350 kW charger, though it could not test the full peak because no faster charger was available.

The Model 3 Long Range peaks at 250 kW and takes under 30 minutes from 10 to 80 per cent, according to Auto Express. Its advantage is the network: Tesla’s 2,774 UK chargers at 447 locations, with automatic battery preconditioning on the way (Zapmap). The P7+ can use the Supercharger sites opened to other EVs, which Zapmap says is now more than half of them, and Zapmap rates those sites at 150 to 400 kW, so the P7+ will often charge below its peak there. See our guide to Tesla Supercharger prices for what each type of driver pays.

Which is more practical?

The P7+ is the larger car, at about 5.07 metres long with a 3.0-metre wheelbase, and it can tow 1,500 kg. Its boot holds 573 litres, rising to 1,931 litres with the rear seats folded. The Model 3 has a 594-litre boot plus an 88-litre front boot, so it carries slightly more luggage despite being the smaller car.

On equipment, Electrifying lists a 15.6-inch screen, an 8-inch rear screen, a head-up display, heated and ventilated front and rear seats with massage, a heat pump and vehicle-to-load at up to 3.3 kW for the UK P7+. It also supports Apple CarPlay and Android Auto, which the Model 3 does not. Both cars offer supervised driver assistance only; neither drives itself on UK roads.

Which is better as a company car?

Both pay 4% benefit-in-kind in 2026/27, so list price decides the bill. A 40% taxpayer in a Model 3 Premium Long Range RWD at £44,990 pays about £60 a month (£44,990 × 4% × 40% ÷ 12). The P7+ figure depends on a UK price that does not exist yet. Our Tesla company car tax guide covers every version.

Who should buy which?

Buy the Tesla Model 3 if:

• You want the lowest running cost: 1.61p a mile at home on WLTP figures in the Long Range
• You want the most range, at up to 466 miles
• You want a confirmed price now, and the Supercharger network

Wait for the Xpeng P7+ if:

• You rapid charge often and want 10 to 80 per cent in around 12 minutes on a fast enough charger
• You want a bigger car with CarPlay, Android Auto and a long equipment list
• You are happy to buy from a brand that launched in the UK in 2025 and is still building its dealer network, which EV Fleet World reported could reach up to 40 dealers by the end of 2026

The P7+ looks like a strong car on paper, but its case depends on the UK price. If it arrives near £45,000, it will be a real alternative to the Model 3 Long Range for drivers who value charging speed and space over efficiency.
