How many models does Changan Blue Whale engine have?
3 Answers
Changan's Blue Whale engine has two models. One is the 1.5-liter turbocharged engine used in CS75 and CS75 Plus, which is the first-generation Blue Whale engine. The other is the second-generation Blue Whale engine, which has not yet been widely applied. The details about the Blue Whale engine are as follows: 1. The 1.5-liter turbocharged engine in CS75 has 178 horsepower and a maximum torque of 265 Nm. The maximum torque speed of this engine is 1450 to 4500 rpm, and the maximum power speed is 5500 rpm. This engine is equipped with direct fuel injection technology and uses an aluminum alloy cylinder head and block. 2. The Blue Whale engine is independently developed by Changan. The Blue Whale engine is not just one engine, but a series of engines.
Currently, there are mainly three generations of Blue Whale engines used in mass-produced vehicles. The first generation is the 1.4T model, initially equipped on the Eado, delivering 135 horsepower with notable durability. The second-generation 1.5T has become the mainstream, powering popular models like the CS75 PLUS and UNI-T, offering 188 horsepower with variable valve technology and available in both high and low power versions. The third-generation 2.0T serves as the performance flagship, delivering 233 horsepower in the UNI-K and CS95, with torque reaching 390 Nm. There's also a newly introduced 1.5T hybrid-specific version, achieving 44% thermal efficiency paired with the iDD hybrid system. Essentially, the Blue Whale family features a modular design at its core, combining cast iron cylinder blocks with aluminum alloy cylinder heads, though combustion optimization technologies are upgraded with each generation.
I drive a CS55 equipped with the JL476ZQCF 1.5T engine, which belongs to the second-generation product of the Blue Whale NE platform. My friend who drives a UNI-V has the JL473ZQ7 1.5T engine—same displacement but with more aggressive tuning. If you're after power, you might want to check out the JL486ZQ5 2.0T engine; when I test-drove the UNI-K last year, the acceleration and push-back feeling were particularly noticeable with a hard press on the throttle. The recently launched Deepal SL03 hybrid uses the JL469ZQ6, a dedicated hybrid engine with some pretty advanced fuel-saving technology. These engines all share platform technologies like the dual-outlet IEM integrated exhaust manifold and fully variable oil pump, but the turbo and ECU programming are adjusted to match different vehicle models.
