The new Denza N8 and N8L had their numbers revealed by the Chinese Ministry of Industry and Information Technology (MIIT). The Chinese automaker continues to impress, leaving much of the competition at charging stations.The claimed range of the Denza N8 is up to 623 miles (1,003 km) from a 130.15 kWh battery. A lower variant is available with a 105.792 kWh battery, which still delivers at least 497 miles of range (claimed CLTC).AdvertisementAdvertisementA larger variant of the luxury EV is also available: the Denza N8L is a long-wheelbase version that gets the 130.15 kWh battery pack as standard, and with that cell in play, it gets up to 596 miles of range (claimed CLTC).The thing is, Denza's been on a roll with their far-reaching range estimates, even once claiming to have the longest EV range in the world with its 1,000 horsepower Z9 GT, but there is a catch (again).Denza N8DenzaDenza vs AmericaOn paper, and based on the CLTC claimed range, the Denza N8 produces PHEV numbers on pure battery power alone. If the numbers were airtight, it would absolutely put other EVs to shame in terms of sheer range. Car News China covered this story and wrote that the CLTC electric-only range of the N8 (with its bigger battery) "is already comparable to the hybrid performance of three years ago."Let's also not forget that Denza's focus is on luxury, so it will come with a whole host of features and amenities, as well as a single- or triple-motor option. With the triple-motor setup, we're getting a total of 1,193 horsepower, while the single motor gets "only" up to 497 horsepower.AdvertisementAdvertisementWe have yet to see a BYD, Denza, or any Chinese EV in the United States, so putting that CLTC figure to the test might take a while, or never happen. BYD also stated that "they don't need the U.S.," so don't hold your breath. However, there is a catch to the CLTC-claimed range, and it's one that you should raise an eyebrow at.DenzaCLTC vs EPAI'll admit the headline might be misleading, but claimed ranges often are, with some being better than others. The MIIT figures for the Denza N8 and N8L look promising, but considering the CLTC testing standard, the claim is a bit optimistic. China's CLTC range tests are conducted in a low-speed environment with stop-and-go city traffic, which is a stark contrast to how the EPA and even the WLTP tests are conducted.Meanwhile, America's EPA range estimates account for highway driving, highway speeds, and fast acceleration. EPA estimates usually yield more realistic and often lower-distance results. Compared to CLTC, you might see about a 30% drop or more between it and the EPA estimate.Driving at higher speeds during EPA tests increases drag, slowing the car and reducing its range. Meanwhile, the CLTC is more optimistic because it puts the car in a very slow-driving scenario, with stop-and-go traffic, to help it recover battery power.Denza N8LDenzaVersus America's Longest Range EVsCar and Driver's list of EVs with the longest driving ranges puts the Lucid Air Grand Touring in the number-one spot. The EPA range of this vehicle is up to 516 miles. However, Car and Driver's own testing yielded 410 miles of "real-world" range. The EPA estimate seems a little far from Car and Driver's result, which is still something to consider when talking about claimed ranges.AdvertisementAdvertisementTo estimate the possible EPA range, let's take 30% off the top. Considering it's an SUV, it's likely not going to beat the Lucid Air Grand Touring, right? Plugging the numbers in – what do you know? We get 436 miles, but let's give the Denza N8 another shot.Now, let's go down the list of Car and Driver and pit the next luxury SUV up against the Denza. Scrolling down, we get the Cadillac Escalade IQ with an EPA estimate of 460 miles, which is still more than the Denza, based on a very speculative estimate (of an estimate).It's important to note that the American cars were tested in America, which has a completely different set of driving conditions from those in China. Range will vary depending on your driving environment, and it's extremely apparent here. Knowing this, will the Denza N8 put all other EVs in America to shame? Probably not, but we can only speculate until the EPA conducts actual testing on this car.Lucid Air Grand TouringLucidThis story was originally published by Autoblog on Aug 14, 2026, where it first appeared in the News section.
