MPG, running costs & CO2 Rating

3.5 out of 5

There's no getting around the fact that the Tesla Model X is expensive, whichever version you choose. With prices now starting at well over £90,000 for the entry-level Model X, it is considerably more expensive than most of its established luxury rivals. Combine this with the fact that the Model X no longer qualifies for the government's plug-in car grant, and the cost becomes a factor that holds it back from scoring more highly.

Of course, the Model X’s electric luxury-car status makes it a fairly unique product for the time being at least, so wealthy eco-conscious owners may not be put off by the price. Although it's out of reach of many car buyers, the Model X’s negligible running costs will help balance out the high price for those who choose a Tesla.

Tesla Model X range & charging time

With its long range and absence of any exhaust emissions, the Tesla Model X certainly has what it takes to save money on running costs compared to a conventional petrol or diesel SUV. However, its high purchase price places it out of reach of many motorists.

There’s one type of user for whom the high purchase price of the Model X might not matter – the small percentage of business drivers whose company-car allowance will stretch to the Tesla’s substantially high five-figure (P11D) starting price. If you belong to this rather exclusive club, it’s well worth considering the entry-level Long Range Plus model against premium seven-seat diesel SUVs such as the similarly priced Mercedes GLS 350d or Range Rover TDV6 – if only for the huge saving you’ll make on company-car tax.

In-depth reviews

A total absence of CO2 emissions means the Model X will cost nothing in Benefit-in-Kind (BiK) company-car tax for 2020/21. This means it’ll cost massively less to run than the aforementioned GLS 350d – the latter’s CO2 figure of over 200g/km places it in the top BiK bracket, attracting the highest company-car tax costs.

Once the purchase cost of the Model X is out of the way, private owners can look forward to some serious savings compared to petrol or diesel SUVs of the same size – most notably a much reduced fuel bill. Electricity is far cheaper than petrol or diesel and all models have an impressive range. This means you’re not limited to short urban trips within dashing distance of a recharging point.

The Long Range Plus and Performance models in the Model X range have the same battery size, but varying power outputs and maximum ranges. The 100kWh battery pack of the Long Range Plus has a 348-mile range but the Performance model manages 340 miles. An overnight charge will cost only a few pounds.

It should be remembered, though, that the car’s actual range will vary between drivers. Tesla admits that range will vary depending on cruising speed, outside temperature and whether your air-conditioning is switched on or off. However, with increasing numbers of fast-charge points appearing at motorway service areas, a mid-journey charge can be scheduled during a lunch stop, making long-haul family road trips a possibility – something not all electric cars can offer. The ever-growing Tesla Supercharger fast-charge network can top up the Model X to 80% within half an hour.

Along with an exemption from VED (road tax), the Model X is also exempt from the annual additional surcharge payable on cars costing more than £40,000.

Insurance

Perhaps due to high repair costs and the Model X’s brisk performance, all versions occupy insurance group 50, the highest banding there is. This compares to the group 45 rating of diesel Range Rovers, although the Mercedes GLS 350d is also placed in group 50. It’s certainly worth obtaining an insurance quote before you decide to buy.

Warranty

Tesla offers an impressive warranty for all cars supplied in the UK, although it’s supplied by AXA insurance rather than Tesla itself. It’s a four-year/50,000-mile policy, while the battery and drive units are covered separately with an eight-year/unlimited-mileage warranty. The main warranty can be extended for up to a total of eight years.

Servicing

Tesla states that its cars require less mechanical servicing than conventional petrol or diesel models, but recommends an inspection every 12,500 miles – or yearly, whichever is the more frequent. Maintenance plans are available to help spread the cost of. Software updates can be performed during scheduled maintenance appointments, or downloaded ‘over the air’ by the car’s on-board internet connection. Tesla suggests that you connect your vehicle to your home’s Wi-Fi network for the fastest possible download time.
