BMW is selling its new 2027 X5 with both a combustion engine and a fully electric drivetrain, as the iX5. Ars Technica argues the electric version is the better buy, citing 460 kW charging and up to 450 miles of range.
Key takeaways
- BMW’s new 2027 X5 line-up includes conventionally fuelled versions and a battery-electric version called the iX5.
- Ars Technica reports that the iX5 can charge at up to 460 kW and offers up to 450 miles of range.
- Ars Technica’s view is that the electric iX5 is the better model of the two to choose.
- A peak charging figure only describes the best case, and real charging times depend on the charger, the battery’s temperature and its state of charge.
- Buyers who cannot charge at home or who often drive long distances in areas with few rapid chargers have the most reason to consider the petrol version.
What is BMW offering with the 2027 X5 and iX5?
BMW has launched a new generation of its X5, a large luxury SUV, and is selling it with two kinds of power. The familiar X5 name covers versions with combustion engines. The iX5 is the battery-electric version of the same vehicle. Buyers do not have to choose between two different models in different showrooms. They get one body and one badge family, and they choose how it is powered.
Ars Technica’s review highlights two figures for the electric model. The first is a peak charging rate of 460 kW, which is high for a production car. The second is a range of up to 450 miles on a full battery. On the strength of these, the publication concludes that the iX5 is the version to buy.
Several details are not covered in the material available here: prices, the exact engine and motor outputs, which markets get which versions, and the test cycle behind the 450-mile figure. Readers should check those with BMW or a local dealer before deciding.
Why is this comparison in the news now?
The new X5 is one of BMW’s highest-volume and most visible models, so a new generation gets wide attention. Its timing also matters. Carmakers have been reconsidering how quickly to move away from combustion engines, and many have chosen to keep offering petrol models alongside electric ones instead of switching completely.
BMW’s approach with the X5 is a clear example of that strategy. It lets a buyer compare the two technologies directly in an otherwise similar vehicle. Ars Technica’s review also takes a firm side, recommending the electric model, which makes the launch a useful case study for anyone weighing the same decision.
What background does a newcomer need?
A few terms help when reading about electric SUVs.
Charging power (kW) is how fast energy flows into the battery. A higher figure means shorter stops, but the figure quoted is a peak. Most electric cars reach their peak only for part of a session, usually when the battery is fairly empty and at a suitable temperature. Charging then slows as the battery fills.
Charger capability matters as much as the car’s. A car rated for 460 kW will only charge at that rate if the charger can supply it. Many public rapid chargers deliver much less, and home wallboxes deliver far less again. At home, charging is normally done overnight, so speed matters less there.
Range is the distance a full battery is expected to cover. Official figures come from standardised tests, and different regions use different tests that give different numbers. Real-world range depends on speed, outside temperature, use of heating or air conditioning, wheel size and load. Motorway driving in cold weather usually cuts range noticeably.
Combustion models refuel in a few minutes at widely available filling stations, but cost more to run per mile in most markets and produce tailpipe emissions.
Who is affected by the choice, and how?
The decision affects people differently depending on how and where they drive.
Drivers with off-street parking and a home charger get the most from an electric SUV. They can start most days with a full battery and rarely need public charging.
Drivers without home charging depend on public networks. For them, a high peak charging rate is useful because it can shorten each stop. Even so, the convenience depends on how reliable and plentiful local rapid chargers are.
High-mileage and long-distance drivers benefit from a long range, because fewer stops are needed. Towing usually cuts an electric vehicle’s range sharply. Buyers who tow should look for real-world data on that specifically, and none is available here.
Company car users and fleets often face tax rules that differ sharply between electric and combustion vehicles. That can outweigh other factors, but the rules vary by country and are not covered by the source material.
Buyers in rural areas or places with sparse charging may find a combustion model more practical, whatever the electric version’s specification.
Where do informed people disagree?
Ars Technica’s recommendation reflects a view that the iX5’s charging speed and range remove most of the practical objections to an electric SUV. Many motoring writers and owners share that view for buyers who can charge at home.
Others argue that headline specifications can overstate everyday convenience. Their points usually include:
- the gap between peak and average charging speeds
- range loss in winter and at sustained motorway speeds
- uneven reliability of public charging networks
- uncertainty about how electric vehicles hold their value over time
Supporters of electric vehicles answer that running costs are usually lower, that home charging means less time spent at fuel stations overall, and that charging networks keep expanding.
There is also disagreement about price. Electric versions of luxury vehicles often cost more to buy than combustion equivalents, though incentives can narrow or reverse the gap. The relative prices of the X5 and iX5 are not known from the material available here, so it cannot be said which version is better value.
What are the practical implications for a buyer?
A structured approach makes the comparison easier.
- Map your driving. Note your typical daily distance and how often you make long trips. If almost all journeys fit comfortably within a fraction of the stated range, range is unlikely to limit you.
- Check your charging access. Find out whether you can install a home charger. If not, look at which rapid chargers near you, and on your regular routes, can deliver high power.
- Compare total cost, not purchase price. Add purchase price, fuel or electricity, insurance, servicing, tax and likely resale value over the period you expect to keep the car. Get quotes for both versions.
- Test drive both. Electric and combustion versions of the same vehicle can feel different, in acceleration, noise and weight.
- Ask about real-world range. Ask the dealer which test produced the range figure and what to expect in winter and at motorway speeds.
- Consider your climate. Cold weather reduces battery range and slows charging. Drivers in cold regions should allow for that.
For a buyer with home charging and mostly regional driving, the case for the iX5 set out by Ars Technica is likely to apply. A buyer who regularly covers long distances in areas with poor charging, or who tows heavy loads, has more reason to look closely at the combustion version.
What should buyers watch next?
Several pieces of information will make the decision clearer once they are available.
- Independent range tests, especially in cold weather and at motorway speeds, will show how close the iX5 gets to its stated maximum.
- Real-world charging tests will show how long the car stays near its 460 kW peak and how long a typical rapid-charging stop takes.
- Confirmed pricing and specifications for each market will settle the value comparison.
- Changes to incentives and vehicle taxes can shift the balance between the two versions.
- Owner reports on reliability will follow once the vehicles have been on the road for some time.
Until those details are known, buyers should treat the headline figures as an upper limit and test them against their own driving patterns.
Frequently asked questions
What is the difference between the BMW X5 and iX5?
The X5 and iX5 are versions of the same new BMW SUV generation. The X5 name covers versions with combustion engines, while the iX5 is fully battery-electric. Ars Technica reports that the iX5 offers up to 450 miles of range and charging at up to 460 kW. Exact power outputs, prices and market availability for each version are not covered here and should be confirmed with BMW.
How far can the BMW iX5 go on a charge?
Ars Technica reports a range of up to 450 miles for the iX5. It is not stated which official test produced that figure, and different regions use different tests. Real-world range is normally lower at sustained motorway speeds, in cold weather, with heavy use of heating or air conditioning, and with larger wheels or heavy loads. Buyers should look for independent tests.
How fast does the BMW iX5 charge?
Ars Technica reports a peak charging rate of 460 kW, which is high for a production car. This is a maximum, not an average. The car reaches it only on a charger able to supply that much power, and usually only for part of a session, when the battery is fairly empty and at a suitable temperature. Charging slows as the battery fills.
Is the electric iX5 better than the petrol X5?
Ars Technica concludes that the electric iX5 is the version to get, pointing to its charging speed and range. Whether it suits a particular buyer depends on access to home charging, typical journey lengths, local charging infrastructure, towing needs and the price difference between versions. Prices are not known from the source material, so a full value comparison is not yet possible.
Can I own a BMW iX5 without a home charger?
Owning an electric SUV without home charging is possible, but it means relying on public charging. The iX5’s high peak charging rate can shorten stops at suitably powerful rapid chargers. How practical this is depends on how many reliable high-power chargers are near your home and along your regular routes. Check local networks before buying, and compare the cost of public charging with petrol.
How much does the 2027 BMW iX5 cost?
Pricing for the 2027 iX5 and X5 is not included in the source material available for this article, so it cannot be stated here. Prices usually vary by market, trim level and options, and government incentives can change the effective cost of electric vehicles. Buyers should get official prices from BMW or a dealer and compare total ownership costs, not just purchase prices.
