I'd rather see an aluminum hood. Every Mazda Miata has had one since 1989 and they're cheap cars (and newer MX5s have an aluminum trunk lid, too)! Aluminum fenders ala Mitsu Evo are pretty impressive, too, but probably don't match up with BMW's standard for durability. Aluminum isn't as bling but it sure is cheap! JD |

The majority of people on these forums really don't know the first thing about cars and it's very off-putting. The fact that people assume all BMW could do is "tune the engine with software" is sickening. They've forgotten what real mods are because like I said, they can just do a simple software tune and be done with the car. |

Yes, and to my point is an even older wording, "caveat emptor".

^ You say it ... I'd like to see what they do to make the engine hold power and torque to the red-line and achieve a fast throttle response. Whether they call it "tuned N54" or "N54/N55 hybrid" or even "S55" is of no value to me

Cars are rarely, if ever, tuned (and by this I mean ecu managed processes, A/F ratios, timing, etc) right off the showroom floor for their absolute best performance, because doing so normally puts a nice ding in MPG or smog testing. If this wasn't the case, the aftermarket would yield very unimpressive results for the dollar. |

Off the top of my head, I can't think of any motors that actually make their peak right AT redline. Even in the world of motorcycles. |

Since the objective is to keep the motor as close to peak hp as possible for as long as possible while accelerating, extending the redline a bit beyond that point allows more time near peak hp (upshifting past peak will put you a bit below peak in the next gear - but not as far below peak as if you were to shift right at peak, and on average your car will stay closer to peak power on the track). I often hear people say to shift at peak torque or peak hp, but this is incorrect. With anything but a CVT transmission (where you can continue accelerating right at peak hp without shifting), shifting well above peak hp (if it can be done safely) is the way to go for maximum performance.

The GT3 3.8-liter makes peak power of 435 hp at 7660 rpm and redlines at 8500 rpm. This is an idea situation assuming the hp stays near peak all the way to redline allowing one to stay in a near peak hp powerband. There is a reason why the best motors are designed this way as the viability of a powerband is the area under the curve, not the peak.

I think BMW does a better job with its DCT gearing, IIRC.

Do any of you really think ///M is going to put out a half assed effort and have to deal with what happened with the S52B32? The US market is the market that makes or breaks ///M sales figures and allows these cars to be built.
Quit all the fortune telling and wait for solid information. It will be a real ///M engine with the ///Magic touch. T |

if this car goes up to $50k range with very basic creature comforts.... my money goes to a slightly used Cayman S. If you want real heritage, there we go P-cars, they didn't let down yet.

Look at the X5M or X6M--these are indications of things to come.... I am sure BMW will be in the 7-7.5K redline range for the 1M, but as another poster said, if they can extend the N54 power band, and not have it drop off like an anvil at 5K RPM, they are going to have a winner on their hands.

I will definitely look at the Cayman while shopping the 1M.....that is a good point....

It doesn't need to have a CF roof, or quad exhausts, or an 8K redline - I'm sure the engineers at ///M are smart enough to not limit themselves by enforcing self-imposed and arbitrary design parameters that never change.
