F30 / F31 / F32 / F33 / F34 / F36 (2012 - current)
I'm in the market for a used touring/wagon 2016 or newer, and I'm debating between the 335d touring and the 340i touring. The 340i will obviously have a slight advantage with power & speed, and the 335d will be more fuel efficient. Can anyone tell me more about the engines specifically, though...
