BYD launched the third-generation Qin Plus DM-i in China today, with a BYD Qin Plus DM-i 220 km range on the CLTC cycle, prices from 79,900 yuan, and a claimed combined range of 2,290 kilometres.
Two of those numbers repay a closer look, and they point in opposite directions.
The 220 km is a smaller improvement than it sounds — ten kilometres on the outgoing car. But the 2,290 km figure, which looks like the marketing number, turns out to be more conservative than BYD's own fuel consumption claim. That is the reverse of how these announcements usually work.
Prices and Variants
| Variant | EV range, CLTC | List | Launch offer |
|---|---|---|---|
| Leading | 140 km | 79,900 | 76,900 |
| Superior | 220 km | 90,900 | 87,900 |
| Excellence | 220 km | 100,900 | 97,900 |
Chinese yuan, for the Chinese market. We have not converted these into rupees, because a domestic price in a country where the car is built reflects that market's duties, not ours. The middle trim appears as both “Superior” and “Beyond” in translation.
Two things stand out. The launch discount is a flat 3,000 yuan on all three variants rather than a percentage, so it helps the cheapest car proportionally most.
And look at the top two rows. Excellence costs 10,000 yuan more than Superior for exactly the same battery, the same range and the same powertrain. That is about 11 per cent more money for equipment alone.
Whereas the step from Leading to Superior buys something measurable: 11,000 yuan for an extra 80 kilometres and an extra 8.1 kWh of battery, which works out at roughly 138 yuan per additional kilometre of range. That is the upgrade worth doing.
Where the 220 km Actually Came From
The outgoing Qin Plus DM-i topped out at 210 km. So the new car's headline is a ten-kilometre gain, and it is worth knowing how it was found.
There are two batteries, 16.2 kWh and 24.3 kWh. Notice that the larger is exactly 1.5 times the smaller.
| Battery | Claimed range | Energy per 100 km |
|---|---|---|
| 16.2 kWh | 140 km | 11.57 kWh |
| 24.3 kWh | 220 km | 11.05 kWh |
Our calculation. The larger-battery car is about 4.5 per cent more efficient per kilometre.
Now do the obvious sum. If the 24.3 kWh pack ran at the smaller car's efficiency, it would deliver 140 × 1.5 = 210 km.
Which is precisely what the previous generation claimed. So the entire ten-kilometre improvement is efficiency, not capacity — a gain of roughly 4.8 per cent, found in the powertrain rather than in a bigger battery.
That is a genuine engineering improvement and worth having. It is simply a different thing from what “220 km” implies next to last year's 210.
The 2,290 km Claim Is More Honest Than It Looks
First, the obvious caution. 2,290 km is not electric range. It is the total a full tank and a full battery are said to cover between them, and the battery-only portion of it is the 220 km above.
But run the numbers against BYD's other published figure and something unusual appears.
| Working from | Total range it implies |
|---|---|
| 65 L tank at 2.58 L/100 km, plus 220 km electric | 2,739 km |
| What BYD actually claims | 2,290 km |
Our calculation from the published tank size and the quoted consumption with the battery depleted. The claim sits 449 km, or about 16 per cent, below it.
Read that the other way round. For the car to cover 2,290 km, the petrol leg has to be 2,070 km on 65 litres, which is 3.14 litres per 100 km — roughly 22 per cent thirstier than the 2.58 figure in the headlines.
The likely reason is that the two numbers are measured differently, with the consumption figure quoted on the gentler NEDC basis. But the practical conclusion is the one that matters.
The big round marketing number is the conservative one here, and the small impressive consumption figure is the optimistic one. If you were budgeting fuel for this car, 3.1 litres per 100 km is the number BYD's own claim implies.
One more thing about 2,290 km: you get it once. It needs a full tank and a full battery together. Refuel without recharging and every subsequent tank is 2,070 km.
Engine and Motor: Do Not Add Them Together
The car pairs a 1.5-litre naturally aspirated petrol engine making 74 kW with an electric motor making 120 kW, which is about 161 horsepower.
You will see those added up to 194 kW somewhere. Do not believe it, and the reason is mechanical rather than arithmetic.
In this kind of hybrid the petrol engine spends most of its working life generating electricity rather than driving the wheels. The figure that describes how the car actually moves is the motor's 120 kW. The engine is there to keep feeding it.
That also separates this from a range-extender, where the engine never drives the wheels at all. A plug-in hybrid like this one can send engine power to the road directly when it suits; our guide to range-extender cars covers the distinction, which readers mix up constantly.
The Cabin Grew More Than the Car Did
This generation is bigger in every direction, and the way it grew is the interesting part.
| New | Change | |
|---|---|---|
| Length | 4,840 mm | +60 mm |
| Width | 1,900 mm | +63 mm |
| Height | 1,498 mm | +17 mm |
| Wheelbase | 2,800 mm | +82 mm |
The wheelbase now accounts for 57.9 per cent of the car's length, against 56.9 per cent before.
Compare the last two rows carefully. The wheelbase gained 82 mm while the whole car gained only 60 mm, which means the overhangs at the two ends actually shrank by 22 mm between them.
In plain terms, the cabin grew more than the body did. Rear passengers get most of the benefit, and the car is barely harder to park for it — the same packaging approach showing up across new Chinese models.
Charging, Screens and Driver Assistance
Charging is quoted at 30 to 80 per cent in as little as 20 minutes. That reads well until you divide it out.
Half of the 24.3 kWh pack is about 12 kWh, so twenty minutes needs an average of roughly 36 kW. On the smaller battery it needs about 24 kW. The clock looks good because there is very little to fill, not because the charging is quick.
Inside there is an 8.8-inch instrument display and a central touchscreen of either 10.1 or 12.8 inches depending on variant.
The notable option is God's Eye B driver assistance with LiDAR, covering navigation-assisted driving in cities and on motorways plus automated parking. A laser sensor on a car at this price is the headline feature of the launch, and it is optional rather than standard.
Is the Qin Plus DM-i Coming to Pakistan?
Nothing has been announced, and a Chinese price tells you nothing about a Pakistani one. This car is built in the market where it is sold, which is precisely why it costs what it does there.
The relevant local news is not this model but the technology underneath it. The same DM-i plug-in hybrid family is already heading here in a different body: our coverage of BYD's Sealion 6 local assembly plans and of its Pakistani price and booking details tracks the version that matters for buyers here.
If a Qin-sized plug-in sedan ever follows, the numbers above are a reasonable guide to what the hardware can do — but the price would be a different question entirely.
Final Thoughts
A sedan with 220 km of electric range, a laser-equipped driver assistance option and a wheelbase of 2.8 metres, starting under 80,000 yuan, explains a great deal about why Chinese manufacturers are reshaping markets elsewhere. The hardware per rupee is the story, not any single number in it.
Read the two headline figures carefully, though, because they behave differently. The 220 km is a ten-kilometre gain won through efficiency rather than a bigger battery. The 2,290 km is a once-only total that, unusually, undersells what BYD's own fuel figure would allow.
And when the specification sheet lists 74 kW and 120 kW, resist adding them. In this kind of hybrid the engine mostly makes electricity, and the number that moves the car is the smaller half of that sum.
