Here's your 40-50 MPG lightweight commuter. Still now word on the exact powertrain, initially it was to be the Ecotec 2.4L but there have been some rumors about using the EcoBoost 1.0L, or the RZR 900 motor. 150-200 horsepower and 1200Ibs would be insane. NHTSA safety ratings be damned, this is a motorcycle!

Anyone heard anything specific lately?
