The engine model used in the Inspire is L15BR, with a maximum horsepower of 194 hp, maximum power of 143 KW, maximum power speed of 5500 rpm, and maximum torque of 260 Nm. The Inspire's engine is a Honda-branded engine, produced by Dongfeng Honda in Huangpu District, Guangzhou. For daily maintenance of the Inspire's engine, the following methods can be used: Use lubricating oil of appropriate quality grade. For gasoline engines, choose SD--SF grade gasoline engine oil based on the additional devices in the intake and exhaust systems and usage conditions; for diesel engines, choose CB--CD grade diesel engine oil based on mechanical load, with the selection standard not lower than the manufacturer's requirements; Regularly change the oil and filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, performance deteriorates, leading to various engine problems. To avoid malfunctions, change the oil regularly based on usage conditions and maintain an appropriate oil level; When oil passes through the fine holes of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter is clogged and oil cannot pass through, it may rupture the filter or open the safety valve, allowing oil to bypass the filter and carry contaminants back to the lubrication areas, accelerating engine wear and increasing internal pollution; Regularly clean the crankcase. During engine operation, high-pressure unburned gases, acids, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls, mixing with metal powder from part wear to form sludge. Small amounts remain suspended in the oil, while large amounts precipitate, clogging filters and oil passages, making engine lubrication difficult and causing wear; Regularly use a radiator cleaner to clean the radiator. Removing rust and scale not only ensures normal engine operation but also extends the overall lifespan of the radiator and engine.

I've been driving the Inspire for three years. The engine models vary by model year. The older 2.0L naturally aspirated version used Honda's K24 series, but the current domestic models all switched to turbocharged engines. The latest model on the road now uses the L15BR 1.5T engine, the same as the Accord, with 194 horsepower paired with a CVT. The hybrid version features a 2.0L naturally aspirated LFB11 engine combined with an electric motor, delivering a combined output of 215 horsepower. Pay special attention to the third letter in the hybrid engine code: 'K' indicates an imported engine, while 'F' denotes a domestically produced one. During my last maintenance, I saw a 2022 hybrid model being repaired in the next bay—the engine cover label read LFB11-H5, and the mechanic mentioned that the third-generation i-MMD system has been tuned for smoother performance after localization.

I've seen too many cases at the 4S shop's after-sales service. The gasoline-powered Inspire exclusively uses the L15B series 1.5T engines, with different letters at the end of the model number to distinguish tuning. The 2025 model, which started selling this year, has been upgraded to the L15C8, with maximum torque increased to 260 N·m. The hybrid version is more special, as it started using the newly developed LEC1 model last year, with a thermal efficiency exceeding 40%. If you see an engine nameplate starting with LFB, it's basically an early model. Remind everyone to pay attention to the engine belt when looking at used hybrid models, as early models are prone to abnormal noises at 60,000 kilometers.

From a technical enthusiast's perspective, the evolution of the Inspire's engine is fascinating. The first generation used the now-discontinued K24W series naturally aspirated engine. The 2018 facelift introduced the L15B Earth Dreams turbocharged engine with VTEC technology but a simplified structure. The highlight is the LFB series hybrid, achieving 41% thermal efficiency through Atkinson cycle paired with EGR exhaust gas recirculation system. The latest L15C engine features improved cylinder head design and more wear-resistant piston coating. Owners are advised to wait until the tachometer drops to 800 rpm during cold winter starts before driving to protect the turbocharger.

When choosing a car, the salesperson explained the model differences to me. Just look at the rear badge—the 260TURBO badge corresponds to the L15BR engine, while the e:HEV badge indicates the fourth-generation i-MMD hybrid system. Open the hood and look for the red emblem on the engine cover; the fuel version has a regular silver nameplate. The hybrid version will forcefully start the engine for warming up at -15°C, and the clicking sound is normal—no need to panic. To check the specific model, refer to the first five digits of the engine number on the vehicle license. For example, last year when I helped my best friend pick up her car, hers read L15CN.
