Is there a difference between the GB standard driving cycle range and NEDC?

nedc range differs from actual by 80%-90%. The following is an introduction about NEDC: Introduction: The full name of NEDC is: New-European-Driving-Cycle, which means "New European Driving Cycle" in Chinese. It can be seen that the current MIIT range standard used in China is actually the European standard. Testing: The NEDC range test mainly simulates urban and suburban environments, with a ratio of 4:1. Since actual road conditions involve many influencing factors, NEDC tests are basically conducted on test benches. Reference Value: The biggest criticism of NEDC is that such theoretically formulated data can sometimes be far from reality, and the reference value of NEDC standards in most countries is not high.

When I bought an electric car back then, I was completely confused by the range. The salesperson said it could go 500 kilometers under NEDC, but in winter, it was even hard to reach 350. Now, the China Light-Duty Vehicle Test Cycle (CLTC) is much better. It's a testing method specifically designed for Chinese road conditions, taking into account our frequent traffic jams and dense traffic lights. NEDC is a European standard, and their tests were conducted under smooth and consistent driving conditions, so the numbers looked good but weren't practical. I've noticed that the CLTC range figures for new cars, though sometimes higher, are actually closer to real-world usage. For example, my colleague's electric car, which is rated for 450 kilometers, can commute 50 kilometers daily for a week and still have 15% battery left, which matches the claim quite well. My advice is to ignore the old data and just look at the CLTC range—it's much more reliable.

As someone who frequently follows automotive data, I must say there's a noticeable difference between NEDC and China's national testing cycle. The NEDC testing procedure is overly idealized, primarily conducting constant-speed tests without considering real-world traffic congestion. China's national cycle adopts the CLTC-P standard, specifically simulating stop-and-go urban driving conditions in China, with a lower average speed setting. Having studied test reports, the same battery might show 600 km under NEDC testing but reach about 650 km under the national standard – but don't mistake this for technological improvement, it's purely a testing standard difference. In actual driving, you'll find the national standard data more realistic, especially when using air conditioning or highway driving, where the power consumption rate generally matches the dashboard display.

I drive for ride-hailing services and spend ten hours on the road every day, so I pay special attention to the accuracy of the range. The NEDC data is too unrealistic—a car advertised with a 500 km range can only run about 300 km with the air conditioning on in summer before needing a charge. The national standard driving cycle is much more reliable, as it considers real-world conditions like traffic congestion and energy consumption. Last month, I switched to a new car with a CLTC-rated range of 550 km, and now I can typically drive around 480 km per day while taking orders. This gap is acceptable to me. I recommend fellow ride-hailing drivers to pay more attention to the national standard driving cycle data—it’s far more practical than the old standards.
