The highway is the perfect place for car's acceleration. I was really enjoyed testing my BMW X5 SUV 2012 with amazing power of 300 kW or 407 hp . This BMW X5 E70 50i has amazing acceleration 0-100 km/h and 0-200 km/h was with 2 persons in the car + 160kg . The BMW X5 50i E70 was with really nice exhaust sound inside and outside of the car, creates a feeling that you are driving BMW X5 M serie sport car ! As soon you press the kick down the 8-speed automatic gearbox shifts immediately!
