Ford Mustang Mach-E Winter Range Detailed In New Study

As many are well aware by now, all-electric vehicle range fluctuates for a number of reasons – including speed, grade, wind, and temperature. However, cold temperatures have a bigger impact on range than most other factors, as many have found out this winter, which is precisely why Ford recently released a guide on how to maximize efficiency when temperatures plunge. That also applies to the Ford Mustang Mach-E, which lost anywhere between 25-50 percent of its range in recent testing by Consumer Reports, depending on temperature. Now, a company called Recurrent has performed its own cold weather testing on variety of new EVs, giving us more insight into this phenomenon.

Every EV the company tested suffered some sort of decline in range during cold weather testing, but those losses also varied considerably. As for the Ford Mustang Mach-E, it lost around 30 percent of its range when driving in freezing temps between 20-30 degrees when compared to a 70-degree day – a number that Recurrent verified itself by using onboard devices and real-time usage data across tens of thousands of data points. In freezing temps, the Mach-E Premium AWD model tested returned 65 percent of its rated range, and 95 percent in warmer temps.

This tied the Mach-E with the Volkswagen ID.4 among mainstream EVs that suffered the largest range loss in freezing temperatures – a title that the Chevy Bolt claimed with a 32 percent drop – but it is worth noting that many of the other models tested here weren’t verified by the company itself – rather, these range loss figures were calculated using onboard telematics for more than 7,000 connected vehicles.

As Recurrent points out, one of the main driving factors behind this loss can be attributed to the fact that the Mach-E doesn’t come equipped with a heat pump like many other EVs, and instead relies on resistance heating, which is known to have a big impact on winter range as energy must be drawn from the high voltage battery to generate heat inside the cabin.

We’ll have more on the Mach-E soon, so be sure and subscribe to Ford Authority for more Mustang Mach-E news and non-stop Ford news coverage.

    All these auto makers knew this before they rolled out their products to the public. When the Lightning got rolled out and there was a conspicuous absence of cold weather towing capacity, that was a clear indication that the numbers were bad. Across the board, auto manufacturers have been obfuscating the limitations of EVs, especially in cold weather, so they could book a ton of orders before the shocking truth came out. Not only is this disingenuous, but it is also a safety hazard. God forbid new EV owners who were unaware of their cold weather limitations have a “Buffalo” moment. Actually, it doesn’t need to be nearly as extreme of an event. These numbers are for loss down to 20 degrees. It gets colder than that. A beach loving Californian who takes the EV to the Sierra Nevada’s for a ski weekend can be in for a rude surprise.

    the issue is not really the loss of range, ICE vehicles also lose range in winter driving. the real issue is still time to fill the battery and available places to do so.

      ICE vehicle don’t lose anywhere near 30%. They can be refueled in 5 min and there are stations to refuel at all over the place.

      Actually cold air being more dense Than warm it is a fact that ICE vehicles develop more HP in the cold. Other cold weather driving may effect mpg,

    I agree they can be refueled in 5 min and there are stations to refuel at all over the place. That is the problem as I see it. Fix that and I believe a lot of the BEV concerns about range will go away.

    Fuel economy tests show that, in city driving, a conventional gasoline car’s gas mileage is roughly 15% lower at 20°F than it would be at 77°F. It can drop as much as 24% for short (3- to 4-mile) trips. IT gets worse on ICE as the temps drop.

      If EVs would just use swappable batteries, their “recharge” time would be shorter an an ICE fill-up.

        Swappable batteries has its own set of problems. You would have to have standardized batteries between all manufacturers. High voltage connections, low voltage connections, coolant connections, skid plate removal, then battery removal. Install new battery, reassemble, drop hoist and you are out the door. Getting it done in a 1/2 hour would be challenging. Now imagine Your typical gas station with enough bays with hoists and people to handle a dozen cars at a time. Now multiply that by all the gas stations we have out there.
        To get to swappable batteries we need a battery that is much more power dense than what we have.
        I’m not against EV’s just pointing out that swappable batteries are a good idea but its a difficult nut to crack with its own problems.
        Go on YouTube and look at a battery removal on a Bolt or F150 and seen the size of these things.

          I’ll repeat my suggestion of a year ago. EVs should have 2 batteries. 1 permanent and 1 smaller, swappable battery. Drivers can plug in and wait, or they can pull the smaller swappable battery out and get going in a hurry. The smaller battery won’t have the range, but that is what you sacrifice for the speed. Also, it is a viable solution for places that won’t have an adequate charging network for decades to come. Yeah, you’ll have to stop every 50 miles, but at least you can keep going until you get somewhere to charge.

            I like that sort of thinking outside of the box. Might add unnecessary weight though. I like the idea of more and faster charging as well as the option for inductive charging (parking lots and parking garages). Small top offs. I have a Mustang Mach-E and, yes, my range has definitely taken a hit. Fortunately, for me, it is not at all causing an inconvenience in my daily driving. But it is definitely a concern for more rural areas than I live in.

          It would be nice to offset the cost of the battery to the fueling stations. essentially making the battery less a part of the cost equation up front and more a part of cost of ownership based upon use.

    I drive a Tesla Model Y and there are no restrictions for winter travel. It is easy to plan ahead to account for colder weather. I can charge the car in the garage and never visit a gas station. There are Tesla superchargers everywhere, and there are few restrictions when it comes on traveling. The Mach-E is known to lose a lot of range during cold weather, and it is a less attractive option if you live in a colder climate.

      According to a poster further down the only Tesla that outshines Mach E in this aspect is the Y ER AWD.

    Mach E was dropped by Consumer Reports for poor reliability. No thank you. Not a surprise Americans aren’t adopting EVs.

      LoL. CR’s recommendations are backward looking trailing indicators useful only for making sure your used car has had its shortcomings remediated.

      You can’t reliably use their recommendations for buying newer MY cars because cars are constantly being refined and improved.

    Ford should have went with a heat pump. Not a surprise that the resistance heater is extremely inefficient. Way to go ford😕

    Did anyone else notice that the Mach-E’s “Verified winter range” is still greater than the same *Verified winter range” of all the Tesla’s tested with the exception of the Model Y LR AWD? The Mach-E’s texting in range is still less of a reduction from EPA range than on Teslas…
