2014 BMW 428i xDrive Convertible 0-60 MPH Test *Video*

Take the BMW 4-Series convertible, drop in the 2.0L TwinPower four-cylinder making 240 horsepower and 255 pound-feet of torque, and add BMW's xDrive all-wheel drive; what would you end up with? A convertible that you could drive all seasons. But we're wondering if the addition of all-wheel drive helps or hurts the 428i Convertible's time to 60 MPH. BMW quotes a 0-60 time of 6.2 seconds for both the rear drive and xDrive models. We put it to the test.
