What engine is used in the CS15?
4 Answers
CS15 is equipped with an EA15 high-performance engine independently developed by Changan Automobile, with a maximum power of 78.5kW, maximum power speed of 5500rpm, and maximum torque of 145Nm. The CS15 is a compact SUV under Changan Automobile, inheriting the brand's unique design language. Its original and sharp front grille highlights an unconventional and rugged temperament, seamlessly integrated with the dynamic and poised body design. The CS15 includes four new models: 1.5MT Comfort Edition, 1.5MT Fashion Edition, 1.5MT Luxury Edition, and 1.5MT Premium Edition.
As a seasoned car enthusiast who frequently researches vehicles, I'm quite familiar with the CS15's powertrain combination. Changan employs its in-house Blue Core 1.5L naturally aspirated engine (model JL473QF), whose four-cylinder design delivers smooth operation. With 107 horsepower and 145 N·m of torque, it's adequately powered for daily commuting, paired with either a 5-speed manual or wet dual-clutch transmission. Particularly noteworthy is its DVVT technology - the dual variable valve timing system effectively controls fuel consumption, achieving around 7L/100km in urban driving. Having driven a friend's automatic variant, I noticed occasional hesitation during low-speed gear shifts, but the engine noise is well-contained, remaining tolerable even when revving up to 4,000 RPM.
Last time I helped my cousin who just got his driver's license choose a car, I researched the CS15's engine. The car comes standard with Changan's self-developed 1.5L engine, which is an economical and practical type. The combination of cast iron cylinder block and aluminum cylinder head makes it durable yet lightweight, with a compression ratio of 10:1 suitable for 92-octane regular fuel. During the test drive, I found the torque output most comfortable around 2000 rpm. When overtaking, the engine speed climbs quickly with a deep press of the accelerator, but acceleration becomes a bit sluggish after exceeding 100 km/h on the highway. The maintenance interval is every 5000 kilometers, and a full synthetic oil change plus three filters costs just over 300 yuan, making it easy to maintain and suitable for young people.
During the Changan technology exchange session, engineers explained the engine design of the CS15. This EA15 model adopts a reverse layout with the intake at the front and exhaust at the rear, paired with a long intake manifold to enhance low-end torque performance. When examining the disassembled model, I noticed it uses a silent chain drive, which is over 100,000 kilometers more durable than a belt. The manufacturer stated it underwent 300 hours of full-load testing, and the piston rings feature DLC coating to reduce friction. One notable detail is the integrated exhaust manifold and cylinder head design, which allows for quicker warm-up during cold starts and better fuel efficiency in winter. Tests showed it starts reliably at -15°C with just three turns of the key.
