The G8X oem PS4S's are 2 seconds quicker (70 sec lap) compared to same sized generic PS4S That performance comes at the expense of 50% less tyre life (I've used that oem tyre). How will the G87 compare to F87 with both on generic PS4S's? When guys start tracking their G87's I think there will be not only a lot less life in their tw200 tyres but the window for a hot lap will be smaller, all because of weight. Will have to wait & see. |

But... do you think G87 is going to be slower because it's heavier? If you do, you're nuts. BMW will never let the G87 be slower than an F87 Comp, nevermind the N55 car. They will just lie as usual on the power numbers. The base G87 will probably be just as fast as the outgoing M2 CS in a straight line. |

I don't know what you're after here, but I can simply say that if you go to the dealer and buy a G87 and compare it with a stock F87 comp, it's going to be faster in all ways. This has always been the case. So yeah, it's heavier, but it's compensated for. You don't have to like it, and subjectively it may fall short, but arguing that because the car is 3800 lbs it can't be higher performance is absurd. Your same logic would dictate that the M2 is already a poor performance car because it's 3500-3600 lbs. We should all be driving Miatas or Lotuses. |

No all I've said is that additional weight will hurt performance. How they negate that will generally result in compromises elsewhere, trade-offs the term you used. Likely tyre wear & maybe brake wear will be the G87's main compromises. I am intrigued though, why would the N55 (as compared to S55) make it less likely that someone could feel the affects of having a passenger in the car? |

Why would you feel it more on the N55? Because it’s got less power. It’s always more noticeable with less power. I say it mainly because that was my experience in South Carolina when I drove both with a passenger. I thought I felt it on the top end. It’s not an instrumented test so could easily be placebo and I wasn’t driving solo back-to-back. |

After seeing the G87 in person, I know it's not the right car for me. But quite frankly, I didn't buy my F87C for purely performance metrics. I think it's a great balance of power and fun. The fact that the car has a playful personality (at the expense of performance) is why I own this car.

it's ugly, heavier, and too tech savvy now. only thing that's better is the S58 engine but I'm already making 200whp more than a stock G87. guess I'll be keeping my OG M2

I got the last new F87 06/21 production and was very close to just waiting for the G87. I'm glad I went with the F87. Some things I like more about the F87 are
-a handbrake which means multi piston rear calipers -7700rpm rev limit vs 7200 on the G87 -250 lbs lighter -looks MUCH better than the G87. Don't tell me "wait till you see it in person it'll grow on you" I didn't have to wait to see the F87 the second it was unveiled I wanted one. I'm not paying $60k+ for a car that has to grow on me -made in Germany vs one in Mexico with a German price tag -I love the f87 interior. Does the g87 have more tech? Sure but I can guarantee all those touch screens will age terribly compared to the f87's real buttons and tachs plus having my climate control in the nav would drive me nuts. -the g87 is also on a modular CLAR platform where 2/3/4 fwd/rwd/awd diesel/gas/electric all share the same platforms which explains the massive weight gain that likely isn't due to structural rigidity increasing.

I track a little but more enjoy the twisty roads in our alpine & surrounding region. Carrying roughly another 200kg (440lb) through corners especially when there is a lot of left/right turning with virtually no straight bits in between would be less enjoyable, slower and wear tyres/brakes much quicker. Did some searching and found the BMW Germany pdf spec docs for each M2 model on release so excludes option variations for different markets, weights (kg) given unladen (ready to drive 90% fuel) & DIN (add 75kg for passenger/luggage), all for 6MT: M2 1495/1570 M2C 1550/1625 M2CS 1550/1625 G87 1700/1775 In the accompanying G87 press doc they say the carbon roof option saves 6kg and the M Carbon buckets save 10.8kg. It will be interesting to see if the G87 after release runs in the annual Bathurst 6hr. It's been won by BMW's for several years now, last year an M2C won up against previous winning F80 & F82 cars. Across the mountain it was quite a bit faster. Though it's a series production race the rules allowed them to fit all the M Performance parts (carbon roof/front guards/bonnet/boot lid) and I believe run the M2CS tune, so on the control tyre it had a good weight advantage with slightly less power of the F80/82. Can't see how the G87 can be competitive with all that weight on a control tyre. |

Beyond that G87 has a huge power advantage but the dynamics simply go away with added weight

With +150 lbs in lightest spec? I think there is plenty of room for improvement over a stock F87 that isn't fully negated by 150 or 200 lbs. Maybe not if you track prepped your F87 and run Ohlins etc.

You all can believe whatever you want to believe to feel better. I own an F87 but I prefer to remain objective. The G87 is going to thrash the old car in any measurable way and that's always how it is. It's going to accelerate faster, stop better, ride better, and turn better. We know this because the base G80 already does and it's made with the same components. Last edited by chris719; 10-25-2022 at 02:13 PM.. |

Lightness is lightness. There's no doubt the G87 will excel well in all areas, including eating tires. It's unfortunate the CLAR platform happens to be so damn heavy.

This might be true for stock cars, but I'd wager that anyone with an S55 car shod with the standard mods will kill the G87 being both lighter, and more powerful for at least a few years.
