Teana engine is imported, imported from Japan. The Teana is a mid-size 4-door 5-seater sedan with body dimensions of: length 4901mm, width 1850mm, height 1450mm, wheelbase 2825mm, and fuel tank capacity of 61.3 liters. The Teana is equipped with a 2.0L naturally aspirated engine and a CVT continuously variable transmission, with a maximum power of 115 kilowatts, maximum power speed of 6000 revolutions per minute, maximum torque of 197 Newton meters, maximum torque speed of 4400 revolutions per minute. Its drive system is front-engine front-wheel drive, with front suspension using MacPherson strut independent suspension and rear suspension using trapezoidal control arm multi-link independent suspension.

Regarding the issue with the Teana's engine, I need to start by discussing its historical changes. In the early years when the Teana first entered the Chinese market, its engines were indeed imported. Nissan shipped complete engines from Japan for installation, ensuring higher quality and performance. However, over the past decade or so, Dongfeng Nissan has localized production, with domestic factories manufacturing the QR25 and VQ series engines themselves. This has reduced costs and made the engines more suited to local conditions. Nowadays, the new Teana models you purchase are almost exclusively equipped with domestically produced engines, unless you opt for special versions like the early flagship models or imported vehicles. After localization, maintenance and repairs have become more convenient, with faster and cheaper parts replacement. However, it's advisable to regularly check the engine's condition during maintenance to prevent durability issues caused by aging. After all, while the quality control of domestic production is relatively stable, it may not match the meticulous craftsmanship of the original imported engines in terms of details.

As a technician who frequently works on Nissan vehicles, I've encountered many Teana owners inquiring about engine origins. Simply put, most engines nowadays are domestically produced. Dongfeng Nissan assembles engines in their Wuhan and Huadu plants with decent reliability and easy maintenance. However, older V6 models or certain modified versions might use imported core components. If engine issues arise, domestic replacement parts are cheaper and quicker to obtain, while imported parts require waiting for allocation. I advise new car buyers to inquire about engine batches at 4S stores - domestically produced engines make vehicles more affordable, but pay attention to manufacturing dates to avoid potential inventory issues. Key regular maintenance includes oil changes and cooling system upkeep to prolong engine lifespan.

I've researched the QR series engines used in the Teana on automotive forums, and most of them are now domestically produced. Nissan is promoting local supply chains to reduce costs. Early imported engines were common, but after 2010, production basically shifted to domestic manufacturing unless it's a high-performance model with some imported components. The core engine design still originates from Nissan's technology, and domestic production doesn't affect quality—the key lies in maintenance. The daily driving experience doesn't differ much, but when buying a used car, it's best to check the engine nameplate to confirm its origin. Simply put, domestically produced engines are sufficient and easier to maintain.

When purchasing the Teana, I was quite concerned about the engine. After consulting experts, I found that the mainstream models are all domestically produced. Dongfeng Nissan's localized engine production makes the price more friendly. However, when buying a new car, I carefully check the manual to confirm the batch. Domestic engines are reliable, but regular oil and filter changes can prevent minor issues. If the engine has problems, the repair costs are lower than for imported ones. Some high-end versions like the VQ35 might have imported parts, so it's recommended to buy from an official 4S dealership with warranty records. During maintenance, pay extra attention to the cooling system to avoid overheating.
