Many BMW enthusiasts cringed when the automaker announced it will be making an X4. Now that it has proved itself through high sales enough for BMW to create a new variant, BMW definitely made the right decision.
The BMW X4 M40i gets some more aggressive styling, a sportier interior and a much more powerful engine. A 3.0 liter turbocharged, 355 hp inline-six engine powers the X4 M40i and that allows it to get from 0-60 mph in 4.9 seconds, which is blistering for an SUV like the X4.
