It was the 2021 Tesla Mannequin 3’s flip for the InsideEVs 70-mph highway range test this week and as anticipated, we now have a brand new freeway vary king. The long-range, dual-motor Mannequin 3 managed to go 305 miles at 70 miles per hour earlier than the state of cost reached 0, and we continued on to drive one other 5 miles earlier than arriving on the Supercharger station the place we began.  

310 miles is the farthest we have been capable of drive any of the automobiles we have examined within the InsideEVs 70-mph vary exams, beating out the RWD Porsche Taycan that Kyle Conner was capable of drive 293 miles on his freeway check. That ought to change as soon as we get a refreshed Mannequin S to check out after which maybe once more after we get our fingers on a Lucid Air.

Range Test Results


It is attention-grabbing to notice that we proceed to see the pattern of Tesla automobiles not having the ability to attain their freeway EPA vary score after we do these 70-mph exams, whereas EVs from most different manufacturers often do. On this case, the freeway EPA vary score is 333.8 miles, and we fell wanting that by a substantial margin.

Maybe if we continued to drive till the car shut down we may have reached the freeway vary score, however we did drive 5 miles past the purpose when the state of cost reached zero. The EPA score does not use a continuing 70-mph as we do for its freeway vary score, so the automobile is not anticipated to attain that. Nonetheless, we’ve noticed that the majority EVs do, which is why we like to match the outcomes of the check to it. 

2021 Model 3 highway range test EPA ratings

The temperature in the course of the drive was within the low to mid 80° F, so we would have liked to make use of the air con. We had it set to 68° F and began out on fan setting #2, however wanted to extend the fan to #3 because the day progressed and the cabin heated up. We drove in Chill mode and set the tires to the factory-spec 42 PSI within the morning earlier than the check. We then supercharged the automobile to 100% earlier than beginning out. 

The common effectivity for the drive was 234 Wh/mi, which interprets to 4.27 mi/kWh (14.5 kWh/100km). That occurs to be the very same common effectivity we noticed after we did the identical 70-mph vary check with a 2019 Mannequin 3 final 12 months. In that check, we drove 290 miles, 20 miles much less. Nonetheless, we must always level out that automobile was a 12 months outdated and had about 15,000 miles on it after we performed the vary check.

The 2021 Mannequin 3 we examined is simply 5 months outdated and has about 6,000 miles on it, so the battery possible has a better proportion of its authentic capability accessible than the 2019 Mannequin 3 did after we examined it. On the finish of the drive, the journey gauge confirmed that we used 73 kWh, in comparison with the 68 kWh used after we examined the 2019 Mannequin 3. 

About our freeway vary exams:

We at all times like to say that these vary exams aren’t excellent. There are variables out of our management like wind, visitors, topography, and climate. Nonetheless, we do our greatest to regulate what we will. We do these 70 mph vary exams to supply one other information level for potential prospects which are searching for as a lot data on the driving vary as they’ll get.

We predict getting over 300 miles at 70-mph can be a nice accomplishment. It makes street tripping a Mannequin 3 really easy, particularly if you consider Tesla’s superior supercharger community. So try the video and tell us what you suppose within the remark part under.
