So what are the differences between the EFFICIENT, SPORT and SPORT PLUS modes?
In the SPORT and SPORT PLUS modes, the waste gates remain closed under partial load and the mass flow is routed through the turbines, to ensure that the turbo chargers are already rotating at a higher base speed even in standby. Moreover, certain special engine control functions are brought into play that accelerate activation of the turbo chargers. This means that the car responds more closely to the accelerator in SPORT and SPORT PLUS modes. Another important point is that we normally have to take the drive train into consideration when it comes to building up torque. As a rule, the engine is able to build up torque at a speed that is much faster than that with which the drive train can cope. You can imagine that the drive train then begins to behave like a torsion spring, which is first stretched out and then vibrates, resulting in juddering. To prevent such judders, it is necessary to dampen the engine's build up of momentum to allow a harmonic progression of its response characteristics. The rigid drive train of the new BMW M3 and BMW M4 is, however, optimised for a fast build-up of momentum, similar to a racing car, with a carbon fibre drive shaft, rear axle rigidly bolted to the body, suitably dimensioned drive shafts, etc. This means that the rigid drive train is also an important factor of the spontaneous entrance of the new BMW M3 and BMW M4. In EFFICIENT mode, everything is more levelled out, with a high orientation towards comfort. In stark contrast is the SPORT PLUS mode, which pays absolutely no attention to any comfort factors. In SPORT PLUS, all filter functions are deactivated and the engine responds directly to movements of the accelerator pedal – but this also requires someone behind the wheel who really knows what he is doing. In SPORT PLUS, everything is transmitted as sharply as a knife, in terms of what the engineering can do to facilitate fast lap times – whether in the engine, transmission, chassis or control systems. |

To answer your thread title - No.

In general terms, warmer engine operating temperatures are better for fuel efficiency, while cooler operating temperatures are better for producing maximum power.

Had my F80Z 6MT for 3 days now and while I'm still getting to know the different throttle modes I can already see that Sport+ is pretty much going to be my default 100% of the time.
Why? Two reasons: 1 - The motor's part throttle response is fantastic, especially above 3k rpm. Very direct, very NA-ish. Also - the transition from part to full throttle seems to minimize lag the most in this mode 2 - I don't like the auto rev match downshifts in the other modes. It's unnatural and awkward although it works very well. Both my wife and I agree that it actually gets in the way. We bought a manual to be in control so let us be in control |

Yep, that's why I bought my M3...for the gas mileage.

Both my wife and I hate the sport+ mode. Way to jerky for normal street driving. I've got it programmed for the m2. Occasionally use it for highway merge / hooligan mode. The its back to m1 sport setting or if its a highway trip we will use the efficient mode.

All jokes about mileage and breaking it and what these cars are capable of aside, the posts linking the BMW engineers describing what happens in each engine mode and why have changed me from DDing in Sport+ to Sport.
Efficient was boring and laggy IMHO, and I was really enjoying Sport+ but every now and again I was experiencing rough movement at lights and jerkiness here and there. I took a really spirited drive a few weeks ago in S transmission mode and found that D had adapted accordingly to be much more sporty/responsive than in the past but jerkiness off the line or at low speed issues were even worse. I tried keeping it in Sport and now the quality of my DDing is much better than in Sport+. Whether I use the paddle shifters or not. |

Plus, efficient mode is slow and hugely laggy, at least in the manual so I can't even enjoy the car like that unless I'm just cruising. To be fair, I haven't used sport much. |

I run Sport 99% of the time. The thing about Sport+ is that it sucks gas dry. I suppose that's ok if you don't mind making a lot of trips to the gas station but I think performance in regular sport mode is excellent for when driving to and from work. Efficient mode just doesn't cut it for me...
