How quick is the 2021 BMW X3 M from 0-60MPH?
The BMW X3 M is incredibly fast considering it to be an SUV of its size. Paddle shifters are located behind the steering which eases the way of shifting gears. While smooth gear shifting acts as an advantage, the car jumps into triple-digit speeds in no time. There is space for 5 people to sit inside the cabin of the BMW. However, the middle occupant on the rear seat is the one who has to compromise the comfort level to some extent because of the underlying transmission tunnel. The 2021 BMW X3 M is an acceleration hustler and takes just 4.1 secs to jump from zero to sixty. It is not the best as the Mercedes AMG GLC 63 does it in a much shorter time frame of just 3.8 secs.
