What’s better, M340i or M340i xDrive?
The m340i vs m340i xdrive — a question of performance the xdrive’s awd hits nearly 4 seconds flat in 0–60-mph tests (even faster with the right wheel upgrades). With about 200 fewer pounds and rwd, the m340i steps off the line a little easier, but slower, and it had slightly longer quarter-mile times as well. With nearly 400 horsepower and a 0–100 km/h time of 4. Drive system, the m340i is a proper sleeper.
