How many seconds does it take for the BMW 3 Series to accelerate from 0 to 100 km/h?

According to official data, the BMW 3 Series accelerates from 0 to 100 km/h in 9.1 seconds. Factors affecting a vehicle's 0-100 km/h acceleration time are as follows: Torque: Torque, in layman's terms, represents how much force is available. The greater the torque, the stronger the force pushing the vehicle, resulting in naturally faster acceleration. The BMW 7 Series 2.0T has a maximum torque of 400 Nm and accelerates from 0 to 100 km/h in 6.3 seconds. The BMW 3 Series has a torque of 400 Nm and accelerates from 0 to 100 km/h in 9.1 seconds. Transmission efficiency: The transmission is the medium for power delivery, inevitably involving power loss. The higher the transmission efficiency, the better the acceleration performance. Generally, transmission efficiency ranks as follows: manual transmission > dry dual-clutch transmission > wet dual-clutch transmission > AT transmission > CVT transmission. The BMW 3 Series is equipped with an 8-speed automatic manual transmission (AT). Power-to-weight ratio: The relationship between horsepower and vehicle weight is called the power-to-weight ratio (unit is Hp/T). The higher the power-to-weight ratio, the faster the acceleration. The BMW 7 Series 2.0T has a power-to-weight ratio of 121 Hp/T and accelerates from 0 to 100 km/h in 6.3 seconds. The BMW 3 Series has a power-to-weight ratio of 144.5 Hp/T and accelerates from 0 to 100 km/h in 9.1 seconds.
I just drove my friend's BMW 330i, which has an official 0-100km/h acceleration time of 5.9 seconds. The actual experience was that the kick-down acceleration was incredibly fierce, with the tachometer instantly hitting the red zone. However, such intense acceleration is hardly necessary for everyday city driving, though it's exceptionally crisp when overtaking on the highway. My model comes with xDrive all-wheel drive, providing more stable starts on slippery surfaces, but it adds over a hundred kilograms to the weight. Last year, I rented a 320i, which was noticeably slower, probably around 8 seconds, but the fuel consumption was significantly lower. For those seeking thrills, I've heard the M340i can hit under 4.4 seconds, though the price is almost on par with the M3. Overall, the 3 Series' power tuning feels very intelligent—smooth at low speeds and aggressive at high speeds.
Last week I tested the M340i on the track - the launch control felt like being kicked in the back! The instrument showed 0-100km/h in 4.4 seconds, 0.4s quicker than the previous 340i. The inline-six engine paired with ZF transmission responds insanely fast, with almost no shift lag. However, the regular 330i's 5.9s is perfectly adequate for daily driving, and the exhaust pops and bangs when you floor it. Note that summer heat affects acceleration - my test in 38°C weather was 0.3s slower than factory specs. For modifications, high-performance tires can improve by about 0.2s, but ECU tuning may void warranty.
