Against 530 km claimed, I get around 300 km at a realistic motorway average of about 100 km/h, and around 250 km if I sit at a steady 120. Consumption starts climbing noticeably above roughly 90 km/h.
Then there is the other half: in Europe a charging stop in practice means 50 kW, which is about forty minutes rather than the numbers quoted for this car.
The useful thing in those two figures is the gap between them. Dropping from 120 to 100 buys you roughly 50 km, and 50 km is often the difference between stopping once and stopping twice.
The number on the brochure and the number on the road
530 km is the figure. I have never seen it, and I do not think anyone driving at motorway speed in Europe will.
| Condition | Range |
|---|---|
| Claimed | 530 km |
| Typical motorway average around 100 km/h | around 300 km |
| Steady 120 km/h | around 250 km |
A note on precision, because it matters here. The 300 km figure is what a real motorway journey produces: an average of roughly 100 km/h once you account for the fact that nobody actually holds one speed for four hours. The 250 km figure is what happens if you genuinely sit at 120.
I have not measured 110, and I am not going to interpolate a tidy table between the two, because the interesting information is already in those two rows.
That is the whole trick with electric range claims. They are not lies. They are measured under conditions that are not the ones you drive in.
I should say plainly that I have quoted this wrong before. An earlier version of my write-up put 300 km against a steady 120 km/h. That conflated a real journey average with a held speed, and 250 is the honest figure for the latter.
Why motorway speed costs so much
Nothing exotic here, and it applies to every electric car rather than this one in particular. Drag rises steeply with speed, and above a certain point that becomes the dominant thing your battery is paying for. In town the Han is efficient and genuinely pleasant. On a motorway it is a five metre saloon pushing air.
What makes it feel worse in this car than the arithmetic suggests is the second half of the problem.
The charging half, which matters more
A 300 km real range would be unremarkable if topping up were quick.
In Europe, in around 90% of the cases I have run into, fast charging means 50 kW. At 50 kW you are looking at roughly forty minutes. The higher charging figures quoted for this car are real, in China, on Chinese infrastructure. Here, most of the time, they are not the numbers you will meet.
This is the single thing I would push back on hardest if a salesperson raised charging speed. Do not take the headline figure as your planning number.
What that does to an actual journey
Work it through rather than taking my word for it.
Say the trip is 300 km each way. Driven at a normal motorway average, that is roughly your whole usable range one way: you arrive with very little and the return leg needs a charge. Drive the same distance pressing on at 120 and you are looking for a charger before you even get there.
That is the practical value of knowing both numbers. On a journey sitting near the limit, easing off to 100 can turn two stops into one, and forty minutes saved is worth more than the twenty minutes of driving time it costs.
Now do the same trip in a combustion car and the stop is five minutes.
I miss something about petrol cars on long motorway runs, and it is not the engine noise. It is the boring, familiar predictability of refuelling. That is the honest emotional version of the arithmetic above.
Where the car is actually good
Around town it is quiet, smooth, quick off the line and comfortable, and five years in that has not worn off. Short trips, home charging, city driving: this is a genuinely nice car to use and the range question barely comes up.
The mismatch is specific. It is long, fast, repeated motorway driving where the gap between the brochure and the road opens up and stays open.
What I would tell someone deciding
If your driving is mostly local and you charge at home, the range figures in the brochure are largely irrelevant to you, and so is this post.
If you regularly do long motorway distances, plan on roughly 300 km between stops at a normal pace or 250 if you drive quickly, plus forty minutes to charge, and decide whether that works for your life before you buy rather than after. If it does, fine. If it does not, no amount of good driving manners from the car will fix it.
And ask local owners what they actually get, because they will tell you a real number for your roads and your chargers. I have written more about why that is the question that matters here.
What do you get at motorway speed in yours, and at what average? I am curious whether 300 and 250 are typical or whether I am unlucky.
FAQ
What is the real range of a BYD Han at motorway speed?
Around 300 km at a realistic motorway average of about 100 km/h, and around 250 km at a steady 120 km/h, against 530 km claimed. Consumption begins to climb noticeably above roughly 90 km/h.
How much range does driving slower actually save?
On my car, dropping from a steady 120 km/h to an average nearer 100 is worth roughly 50 km, which is often the difference between one charging stop and two.
Why is the real range so much lower than the claimed figure?
Because drag rises steeply with speed, and claimed figures are measured under conditions that are not motorway driving. It is not specific to this car; it is just larger than most buyers expect.
How fast does a BYD Han charge in Europe?
In about 90% of the cases I have encountered, fast charging in Europe means 50 kW, which works out at roughly a forty minute stop. The higher charging figures quoted for the car are real on Chinese infrastructure rather than on what you will typically find here.
How should I plan a long trip in a BYD Han?
Assume around 300 km between charges at a normal motorway average, or around 250 km if you intend to press on at 120, plus a forty minute stop at 50 kW. If that pattern works for the journeys you actually make, the car is fine.
Is the BYD Han efficient in town?
Yes, and it is the nicest place to use it. Quiet, smooth and comfortable, and the range question barely arises on short local journeys with home charging.
Did you measure range at other speeds?
I have reliable figures for a normal motorway average of about 100 km/h and for a steady 120, and I know consumption starts rising above about 90. I have not measured 110 and I am not going to interpolate numbers I did not record.
