Changan CS55 Plus HEV. China's New Fuel-Sipping SUV Launches August 18, 2026
If you're in the market for a small SUV that's easy on the gas and not a pain to charge every night, Changan has good news for you. On August 18, 2026, the company will unveil an improved hybrid version of its popular CS55 Plus, which uses an engine with a thermal efficiency that would make any gasoline enthusiast weep with joy.
Changan has made some significant upgrades and improvements over the existing model, including new BlueCore hybrid powertrains, a much-needed exterior overhaul, and a number of other tweaks to appeal to everyday buyers. Here's everything we know about the upcoming launch of the CS55 Plus HEV.
A Hybrid Engine With a Thermal Efficiency That Would Make Gasoline Car Enthusiasts Cry
When it comes to engines, thermal efficiency is a metric that determines how well the potential energy in gasoline is converted into mechanical energy by the engine and not lost as waste heat. Put another way, it's a measurement of how much fuel goes into making the car move rather than just being lost as waste. For a regular gasoline engine, thermal efficiency hovers around 35 to 38 percent for most vehicles. But Changan's new 1.5-liter turbo engine has a peak thermal efficiency of 44.28 percent and an average of 40.9 percent in everyday driving.

Changan has engineered the 1.5-liter turbo engine to generate 110 kW of power on its own, with a combined 180 kW from the front electric motor. Additionally, the motor can utilize a battery that can release electricity at an incredible 50C rate, which provides enough power for the front motor to deliver strong surges of acceleration when needed. With the combined power of the hybrid powertrain, the CS55 Plus HEV should have enough oomph to tackle everyday driving, highway cruising, and acceleration from any traffic jam with ease.
The fuel economy figures for the CS55 Plus HEV are equally impressive.
While Changan hasn't officially released any numbers for the CS55 Plus HEV, the same BlueCore hybrid powertrain is used in the larger CS75 Plus HEV, and the figures for that model give us a good baseline to estimate the fuel economy for the CS55 Plus HEV. In the case of the CS75 Plus HEV, it records a city fuel consumption of 3.54 L/100km or 66.5 mpg, and 4.67 L/100km or 50.4 mpg on the highway. Changan claims that its BlueCore hybrid technology can reduce the city fuel consumption of SUVs to as low as 3L/100km or 78 mpg for the CS55 Plus HEV, putting it right at the top in terms of fuel economy if the figures turn out to be accurate. If the fuel economy figures for the CS55 Plus HEV turn out to be anywhere near the top end of Changan's estimates, it would be one of the most fuel-efficient compact SUVs sold in China.
A New Exterior Inspired by the Changan CS75
While Changan has made huge improvements to the CS55 Plus HEV's thermal efficiency and overall powertrain, it wasn't enough for the company, so it set about redesigning the CS55 Plus's front end. The new CS55 Plus HEV features a V-shaped front grille that makes it look more premium than the standard CS55 Plus. New aerodynamic wheels also add to the premium look and feel of the CS55 Plus HEV while reducing drag, which in turn reduces fuel consumption even further.
The rest of the exterior changes are relatively minor, as most of the bodywork remains similar to the standard CS55 Plus. The most noticeable change is the blue "HEV" badge on the rear bumper, which is a subtle way of indicating the hybrid powertrain used in the CS55 Plus HEV. In keeping with the self-charging nature of the CS55 Plus HEV, it only has a fuel filler door on the left-hand rear quarter. There are no charging ports anywhere on the CS55 Plus HEV, as the car utilizes the fuel engine to keep the battery charged at all times.
Dimensions and Chassis
According to the filing with China's Ministry of Industry and Information Technology, the CS55 Plus HEV measures 4,550 mm from end to end, 1,868 mm from side to side, and 1,675 mm tall. From front to rear, the CS55 Plus HEV has a 2,656 mm wheelbase, and it fits squarely in the segment of compact SUVs. With that said, the CS55 Plus HEV should be big enough to seat a family of four without feeling too cramped, while also being easy to maneuver in confined spaces.
The CS55 Plus HEV employs independent front and rear suspensions, with McPherson struts on the front and a multi-link setup on the rear. On the whole, it's a pretty standard formula for an SUV, and it offers a blend of comfort, performance, and control on the road.
An Estimated Starting Price Around RMB 95,000 or USD 14,000
Changan hasn't announced any official pricing for the CS55 Plus HEV, but the company has a history of being fairly transparent about the costs of its vehicles. Right now, the petrol-powered CS55 Plus has an estimated starting price of RMB 92,900 (USD 13,800) and goes up to RMB 109,900 (USD 16,300). Industry insiders are expecting the CS55 Plus HEV's starting price to be around RMB 95,000 (USD 14,000) or just a tad over the starting price of the petrol-powered CS55 Plus.
That's the beauty of the CS55 Plus HEV - it doesn't make buyers pay extra for a hybrid powertrain that doesn't require plugging in their cars every night. As such, it should compete directly with petrol counterparts while also managing to undercut the competition on fuel economy. For perspective, the related CS75 Plus HEV, which utilizes the same hybrid powertrain, starts at RMB 109,900 (USD 16,180). Meanwhile, Changan's smaller Eado HEV sedan only costs around RMB 79,900 (USD 11,760) on promotional pricing.
Why This Launch Matters
The Chinese automotive market for compact SUVs is becoming increasingly competitive by the day, with buyers constantly seeking better fuel economy. A hybrid powertrain is the most viable alternative for most buyers who don't have the luxury of home charging, especially in apartment complexes and other places where private parking is unavailable. As such, a hybrid powertrain is an excellent middle ground for fuel-conscious buyers who want something with better fuel economy than a standard petrol SUV but don't have the means to charge their cars at home.
Additionally, this new launch is rather important for Changan as a company itself, as it looks to regain its ground in the Chinese automotive market. Sales figures for the CS55 Plus have been quite erratic over the past year, peaking at over 7,000 units sold in a single month before dipping steadily to more stable but lower numbers in recent months. As such, the CS55 Plus HEV has the potential to do well in the market if it can appeal to buyers who are looking to buy an everyday hybrid SUV.
Final Thoughts
The new Changan CS55 Plus HEV looks set to become a big hit in China this year, as it offers incredible thermal efficiency, a self-charging hybrid powertrain, and a price that's right around the petrol models for everyday buyers. More details about the CS55 Plus HEV, including its fuel economy figures and final pricing, will be available when Changan officially launches the car on August 18, 2026.
