Norway's -27°C Winter EV Test: Chinese Cars Beat Tesla on Range

If you've been told that EVs are all more or less equal in cold weather, Norway just proved that wrong — loudly. The El Prix annual winter EV range test ran a 400 km route through Norwegian mountains and valleys at -27°C, and the gap between the best and worst performers was nearly 18 percentage points. That's not a rounding error. That's the difference between getting where you're going and standing on a frozen roadside wondering where things went wrong.

The headline result: six of the top ten performers were Chinese-made EVs. Tesla — one of the most recognizable names in the industry — landed deep in the bottom half of the pack. And if you're shopping for an EV in Canada, where the prairies and northern regions regularly hit -30°C to -40°C in January, this test is probably the most relevant real-world data you're going to find anywhere.

What the El Prix Test Actually Measures

The El Prix test isn't a lab simulation. It's a real-world winter drive on actual Norwegian roads, in actual Norwegian winter weather. Vehicles are driven until the battery reaches 10% charge, then fast-charged from 10% back to 80%. The test measures how far each vehicle actually travels compared to the manufacturer's stated range — which is almost always calculated at a comfortable 23°C.

That 23°C baseline matters. Every EV on the market has an official range rating, and essentially every one of those ratings was established in conditions that look nothing like a Canadian January. Norway, with its mountainous terrain, extended sub-zero temperatures, and demanding road conditions, is about as close as you can get to a controlled real-world stress test for cold weather range.

This is also why Norway is the most useful comparison available for Canadian buyers. There's no equivalent Canadian test with this level of rigour and this many vehicles. Norway has the infrastructure, the climate, and frankly the political will to take cold-weather EV performance seriously in a way that most other countries haven't matched yet. If you're trying to figure out how an EV will perform on a January commute between Edmonton and Red Deer, the El Prix results are your best available proxy.

The Results: Chinese EVs Dominated

Let's go through the numbers directly, because they tell a clear story.

The top performers by range retention at -27°C were:

• MG S6: lost 29% of rated range (tied first)
• Hyundai Inster: lost 29% of rated range (tied first)
• MG IM6: lost 30.4% (third place)
• KGM Musso (Korean): lost 30.6%
• Voyah Courage: lost 31.8%
• Zeekr 7X: lost 33.1%
• KIA EV4: lost 34.3%
• Xpeng X9: lost 35.6%

Then there's Tesla, which posted a 40.1% range loss. And the Ford Capri, which lost 47.1% — nearly half its rated range, gone, in the cold.

Of the top ten vehicles in the overall test, six were Chinese-made and three were Korean. That breakdown didn't happen by accident. As one analyst put it bluntly: "Top performers have always been Chinese and Korean cars." This isn't a one-year anomaly. It's a pattern.

One notable absence this year: BYD didn't enter a vehicle. BYD has been a strong performer in previous cold-weather tests, so their absence left a gap at the top of the field. Whether they return next year remains to be seen, but their track record suggests they'd likely be competitive if they did.

And the MG result deserves special attention. MG is a brand that many Canadian buyers still associate with the old British sports car marque, not realising it's now owned by SAIC Motor in China. The S6 tying for first at -27°C is not a fluke — it reflects real investment in thermal management and battery engineering.

Why Battery Preconditioning Matters

The single biggest technical differentiator in cold-weather EV performance isn't battery chemistry or motor type. It's battery preconditioning — the vehicle's ability to warm the battery pack to an optimal operating temperature before and during driving.

Lithium-ion batteries don't like cold. At -27°C, an unmanaged battery pack will have dramatically reduced capacity and slower charge acceptance. The vehicles that performed best in Norway aren't just equipped with better batteries — they're equipped with better systems for managing those batteries in cold conditions. They're actively heating the pack before departure, maintaining thermal stability during the drive, and preparing for fast charging before the vehicle even arrives at the charger.

This is why the 10-80% fast charge portion of the El Prix test is just as revealing as the range portion. A vehicle with poor preconditioning will charge slowly in the cold even when connected to a high-powered charger. The cars that topped the leaderboard didn't just go farther — they recovered charge faster too. That matters enormously on a long winter road trip where you're stopping to charge in -25°C weather.

Chinese automakers have been investing heavily in cold-climate testing, specifically because they're targeting European, Canadian, and northern Asian markets where cold weather performance isn't a nice-to-have feature — it's a purchase requirement. That investment is showing up directly in the El Prix results.

For a closer look at how range varies across different Canadian conditions, the EV Winter Range Test Canada 2026 breaks down what to expect across different provinces and temperature bands.

What This Means for Canadian Buyers

Canada's winters are not Norway's winters — they're often worse. In Winnipeg, Regina, and Saskatoon, January temperatures routinely hit -30°C. In northern Alberta and the Northwest Territories, -40°C is not unusual. The El Prix test at -27°C is actually a mild entry point for what Canadian buyers face.

The practical implications here are straightforward:

• Expect to lose 30-50% of your official range in severe cold, depending on which vehicle you buy and how cold it gets
• The gap between the best and worst performers is wide enough to matter — nearly 20 percentage points separates the MG S6 from the Ford Capri in this test
• Chinese and Korean EVs are currently leading on cold-weather performance, not just on price
• Tesla, despite its brand recognition and Supercharger network dominance, is not a leader in cold-weather range efficiency

That last point is worth sitting with. Tesla's Supercharger network is still an advantage for long-distance travel in Canada. But the vehicle's cold-weather range retention is measurably worse than the top Chinese competitors. For someone doing daily winter driving in Saskatchewan rather than cross-country road trips, the charging network matters less than how far the car goes on a cold morning.

There's also a safety dimension to this conversation. Some buyers have concerns about buying Chinese EVs — quality, build standards, parts availability. Those are legitimate questions worth researching. The Chinese EVs Safety: Euro NCAP Ratings post goes through the crash test data in detail. The short version: most of the Chinese brands performing well in Norway have also scored well in Euro NCAP testing. Performance in cold weather and structural safety aren't in conflict.

The reality for Canadian buyers is that the market is changing. Chinese EVs are arriving in Canada — some directly, some through existing brand networks (MG through SAIC dealerships, for instance). The range data from Norway should make those vehicles worth taking seriously, not dismissing based on brand unfamiliarity.

And the planning math is simple: in severe Canadian cold, plan on 60-70% of your official rated range on the worst days. Better preconditioning systems can push that closer to 70-75%. Buying a vehicle with weaker thermal management means planning for 50-55%. On a 400 km battery, that difference is 80 km — and in northern Alberta in January, 80 km is not abstract.

How to Maximize Your Winter Range

The El Prix test results show what the vehicles can do. What they can't measure is what you do as a driver and vehicle owner. There are real, practical things that move the needle on winter range.

Battery preconditioning is the first one. If your vehicle has a preconditioning feature — and most newer EVs do — use it. Start it while the car is still plugged in so you're using grid power to warm the battery, not drawing down your range before you've even left the driveway. This alone can recover 10-15% of range on cold mornings.

Winter tyres are not optional in Canada. All-season tyres get harder and less grippy below 7°C, and you're fighting more rolling resistance and less traction. Winter tyres improve safety and reduce the energy the motor has to use to maintain speed on cold, slippery roads. The range benefit is secondary to the safety benefit, but both are real.

Keeping the battery charged above 20% in severe cold helps maintain thermal stability. The bottom portion of the battery is more vulnerable to cold-related capacity loss, and the vehicle's thermal management system works harder when the pack is nearly depleted. A quick top-up to 60-70% before a cold drive is better than running it down and trying to recover from 5% in -30°C weather.

Cabin heat is a significant draw on winter range — typically one of the largest single consumers in cold weather driving. Seat heaters and steering wheel heaters are more efficient than the main HVAC system for keeping you comfortable. If your vehicle lets you prioritise radiant heat over blowing hot air, do it. The range difference is noticeable.

Parking in a garage, even an unheated one, makes a measurable difference. An unheated garage at -5°C versus an outdoor parking spot at -25°C means your battery starts warmer and requires less energy to bring to operating temperature. If you have any indoor parking option, use it.
