BMW E82 1 Series M Coupe weighs in at 3,351 pounds with a full tank of gasThe guys at Axis of Oversteer weighed a 1M Coupe with a full tank of gas. The result? 3,351 pounds. This is pretty impressive and lighter than an E92 M3 by about 200 pounds. BMW USA lists the curb weight for the 2011 135i at 3373 so the 1M undercuts it slightly. It is nice to see the parts off the M3 did not come with considerable weight gain.
