Electric car winter ranges REVEALED! | What Car?
com for a great deal on your next car. So we carry out these range tests twice a year at the height of Summer and in the depths of winter, to see how far electric cars can really go on a full charge and how efficiently they use the electricity stored in their batteries. Just like in our previous tests as much as wed like to do this on the public road things like traffic lights, cyclists and roundabouts would mean it would be impossible to keep 12 cars together in Convoy, so they wouldnt be driving in exactly the same conditions. Making the test unfair and then, of course, theres the safety side of things as well, because deliberately running out of juice with other Road users around could be pretty dangerous thats why we always use our private Proving Ground in bedfordshire. We follow a relatively simple test route of around 15 miles, which includes 2.6 miles of simulated. Stop start Urban driving four miles at a steady 50 miles an hour and 8 miles at a constant 70 miles an hour. The reason for the high percentage of high speed cruising is that drivers who want to travel long distances in one hit are likely to be using the motorway. The first step was to fully charge the 12 cars we had and then leave them out in the open overnight. This was for roughly 14 hours between zero and two degrees Centigrade. Ambient temperatures early the following morning, all 12 were plugged back in again to check.
They were fully charged now its important for this test, of course, to make it fair and to do that were driving all of these electric cars at the same time in the same conditions and were setting them up all the same as well. So that means, if there are a choice of Drive modes, then we are allowing them to be put in eco mode. The regenerative braking is going to be left in its default setting and unfortunately, despite the Temptation, we are not allowing heated seats or heated steering wheels. Our original plan was to set the air conditioning in all 12 cars to 21 degrees, but during preparation, the day before testing, we noticed that the mgs interior felt quite a bit chillier than it was claiming. So we used a digital thermometer to see what the actual temperature was in each car. The Jaguar i pace was used as our Benchmark setting its climate control system to 21 degrees and leaving the doors closed for 20 minutes to allow the interior temperature to stabilize. During this time, we measured the temperature at roughly the chest height of the driver and we recorded 19.5 degrees. So we set about the lengthy task of matching this in our other 11 contenders and for the record, it was only the Renault Megan which was able to achieve this temperature with the climate system set to 19.5 degrees. The aura funky cat needed its aircon dialed up to 22 degrees, while the mg4 required its interior temperature set to 23 degrees.
The reason this matters is that heating and evs interior uses up precious battery power that could otherwise be used to get the car further down. The road so to make things as Fair as possible, while providing a reasonably warm and consistent environment for the driver. It was important to normalize things as much as possible. The actual temperature outside was between three and six degrees during our testing, and it was a cloudy day. So the interior heaters were running continuously and yes before our viewers from Alaska explained that three degrees isnt cold, its pretty cold for Britain and still gives us a good indication of real world winter conditions for cars in this country and so to our results. Unsurprisingly, it was the car, with the smallest battery that ground to a halt. First, the mini electric managed just 113 miles, so any long journey will inevitably involve frequent charging pit stops and high levels of range anxiety more positively. The mini was the most efficient core in our entire lineup averaging an impressive 3.9 miles per kilowatt hour, so theres an urban and Suburban run around particularly for multi car households. It can still make sense. The New Aura funky cat should have a broader appeal. It has more space in the back costs about the same to buy and it promises an extra 52 miles from every full battery charge. Sadly, in our real world test, it beat the mini by only 17 miles and it posted the third worst efficiency figure of all 12 cars at 2.
9 miles per kilowatt hour. Something thats particularly disappointing, given its relatively small size. The funky cat also fell further short of its official wltp range. The next 50 miles went by without any further dropouts before the field began, to rapidly Whittle itself. Down next to dye was the Cooper born at 182 miles. This was a car we tested back in the summer when the temperature was between 24 and 29 degrees back then it managed 219 miles showing that cold temperatures really do make a difference to range. In this case, the Bournes range was more than 20 percent. Worse in cold weather, for this test, we included two Renault Megans, one with 20 inch Alloys and one with 18 inch Alloys. Our Theory, and indeed the common perception – was that the bigger your Alloys, the worse your range will be. But surprisingly, it was the Megan on the smaller Alloys which ran out first, but the difference was only two miles and this doesnt mean bigger Wheels, wont impact range on other, makes and models the family friendly, Volkswagen ID Buzz, dropped out of the running at a respectable 192 miles next, this was the second most energy hungry car in the lineup, with an average efficiency of 2.5 miles per kilowatt hour. The fact it has such an enormous interior to heat probably didnt help its cause. But while this doesnt have the longest range out there in cold weather, the buzz is still a fantastic electric car and to find out what makes it so great click on the link to watch our full review.
The range topping long range version of the mg4 dropped out four miles later on 196 miles, thats pretty far from its official 270 mile range, but this is one of the cheapest options here. So, while its not a perfect electric car for the money, the mg4 is very impressive. Indeed, just one mile later it was the Jaguar i pace that died. The Jag was the least efficient of the Dozen returning just 2.3 miles per kilowatt hour, while the tall and boxy Buzz has a good excuse for its relative inefficiency. The i pace really doesnt and would likely cost the most to run in electricity compared to all the other cars in this test. The final four werent even breaking a sweat at this point and all went past 250 miles, but the Genesis gv60 finally died at 251 miles 10 miles later. The BMW I4 gave up the ghost on 261 miles. This I4 had 19 inch Alloys, while in our summer test we had an i4 on 20 inch Alloys. This time around, the I4 suffered a dead battery 56 miles earlier than it did in the summer, despite having smaller wheels for a winter test which, on paper, should improve efficiency, although, as proven by the mcgans that isnt always the case. Curiously, the Nissan area went into limp mode at around 250 miles, but it just kept on going. The performance deteriorated pretty drastically, but it didnt actually stop dead until it had traveled 269 miles in total that helped it get closest to its official wltp range.
It fell. Just 16.4 percent short, but that still wasnt quite enough to beat the mighty Tesla Model y. The long range version of Britains best selling EV managed a hugely impressive 272 miles other than the much lighter mini electric. It was also the most efficient car in the lineup averaging 3.6 miles per kilowatt hour, plus the model y ran out of juice just 32 miles earlier than the same version did in our warm weather test. So those are our full results. But the final question to ask is how accurate are efficiency meters with Energy prices at an all time high, how efficient the EVS use the electricity stored in their batteries is under the spotlight like never before all electric cars have built in meters to help you monitor This usually displayed in either miles per kilowatt hour or what hours per mile its the equivalent of a fuel powered car, showing you how many miles per gallon its achieving? Should these meters be relied upon, though? Well our tests show that the answer is it depends. Some were spot on, While others, either over red or under Red, by a fair margin. The funky cat promised 15 better efficiency than it was actually delivering, while the Cupra and gv60. Also over promised the mini, on the other hand, claimed 3.7 miles per kilowatt hour, which is an efficiency figure that would have still made it the most frugal user of electricity here, but our calculation showed it was actually delivering fractionally under 3.
9 miles per kilowatt hour. So there you have it are you surprised, shocked by these results, tell us in the comments below and if youve enjoyed this video.
