This is convenient; I do not need to break to maintain a specific speed. My question for current i3 users, does the i3 cruise control function the same way? Is there any fluctuation when CC is engaged? Thanks.
I am still waiting for my i3 to get assigned a boat to bring it to me (hopefully today!), but I'll take a stab at answering. The BMW spec does clearly imply that regen is used if needed during cruise to keep speed correct even when going down hill. My guess is that your 335i will accelerate above your set speed on a steep enough downhill where engine compression cannot provide enough braking will above your set speed.
On the other hand, if you only use your cruise above 85 MPH where engine braking combined with wind resistance can handle any hill steepness, they you are probably correct.
