Models equipped: The 4a91t engine is widely used in models such as the Southeast Lingyue, Mazda 2, Dongfeng Fengxing Jingyi, Zotye Z300, and Zhonghua FRV. 2. Performance: The 4a91t engine has a maximum torque of 215N.M and a power output of 115kw. The MIVEC technology used in this engine not only optimizes the valve opening timing phase but also changes the valve opening stroke to increase air intake.

I've driven many car models, including those with the 4A91T engine, and high fuel consumption is indeed common, especially in city traffic jams. There are quite a few reasons: this engine is turbocharged, and at low speeds, the turbo response is slow, fuel efficiency is low, and it tends to consume more oil. Poor maintenance is also a big issue—for example, a clogged air filter or aging spark plugs can lead to incomplete combustion and wasted gasoline. Driving habits have a significant impact; sudden acceleration and hard braking can cause fuel consumption to skyrocket. I've tried driving more smoothly and saved quite a bit. Low tire pressure and an overloaded car also add to the burden. I recommend regular maintenance, changing the engine oil and air filter every 5,000 kilometers, and starting smoothly—this can reduce fuel consumption by about 10%. In the long run, saving fuel means saving money, and you'll spend less time waiting in line at gas stations, saving time and peace of mind. Remember, prevention is better than dealing with headaches when the car breaks down.

Powertrain: The Wraith is equipped with a 6.6-liter twin-turbocharged V12 engine, delivering 632 horsepower and a maximum torque of 820 Nm. This engine reaches its peak power at 5600 rpm and its maximum torque between 1500 to 5500 rpm. It features direct fuel injection technology and uses an aluminum alloy cylinder head and block. Paired with this engine is an 8-speed automatic transmission (8AT), which enhances gear shift smoothness and fuel efficiency. Moreover, the 8AT transmission offers better reliability and durability compared to dual-clutch transmissions. 2. Suspension: The Rolls-Royce Wraith employs a double-wishbone independent suspension at the front and a multi-link independent suspension at the rear. The double-wishbone suspension helps reduce body roll, thereby minimizing brake dive. It consists of upper and lower wishbones with an additional linkage between them. The multi-link suspension is an evolution of the double-wishbone design, where each wishbone is replaced by individual linkages. This setup improves the tire's contact with the road surface.
