CLTC and WLTP are two different lab tests used to state an EV's range. They use different driving cycles, so the same car gets different numbers, and CLTC figures are usually higher. Compare range only under the same label, and expect real driving in Johor to give less, depending on speed, air-con and load.
What do CLTC and WLTP stand for?
CLTC is the China Light-duty vehicle Test Cycle. WLTP is the Worldwide Harmonised Light Vehicles Test Procedure. Both measure range in a laboratory on a set driving pattern, so that different cars can be tested under the same conditions. They are tests for comparison, not a promise of what you will get on the road.
Why do the two numbers differ?
Each test uses its own driving cycle, with different speeds, stops and test conditions. The CLTC cycle generally includes more low-speed driving than WLTP, and an EV uses less energy at lower speeds, so the CLTC figure for the same car is usually higher. Neither number is wrong. They answer slightly different questions.
What figures does Dongfeng give for the Vigo and 007?
Our model pages show the Dongfeng Vigo at 471 km on the CLTC cycle. The Dongfeng 007 Premium is up to 650 km on CLTC and 530 km on WLTP, and the 007 Prime is 565 km on CLTC and 389 km on WLTP. These are the manufacturer figures as listed on our model pages, not our own measurements. We show a CLTC figure for the Vigo and no WLTP figure, so do not compare the Vigo number with a WLTP number for another car.
How do I compare range fairly?
Compare like with like: a CLTC figure with another CLTC figure, and a WLTP figure with another WLTP figure. Always ask which test and which variant a number belongs to. We do not convert between the two, because there is no single fixed ratio that fits every car. Here is what to ask:
- Which test is this range figure from, CLTC or WLTP?
- Which variant does the figure belong to?
- What does the car's trip display estimate for my usual route?
- How much does the estimate change with air-con and highway speed?
- Is my daily distance comfortably inside the range?
What range will I get in daily driving in Johor?
Less than the lab figure in most cases, and it varies. Highway speed, air-con use, passengers and luggage, tyre pressure, hot weather and how you drive all change it. We make no promise for any car. A better method is to add up your usual daily distance and see how comfortably it sits inside the range. Our guide on whether an EV is practical for daily driving in Johor shows how.

Questions
Which is more realistic, CLTC or WLTP?
WLTP figures are generally lower than CLTC for the same car and are often closer to everyday driving, but neither is a promise. Your own result depends on how and where you drive.
Can I convert a CLTC figure into WLTP?
Not reliably. There is no single ratio that fits every car, so we do not convert. Ask for the figure under the test you want to compare.
Why are the range figures on your model pages labelled CLTC?
Because CLTC is the test behind the range figure we list for the Vigo and 007. Where Dongfeng also gives a WLTP figure for the 007, we show it too.
Where can I see how the car behaves on my own route?
On a test drive. WhatsApp us the model and a time that suits you, and we will have the car charged and ready.
