Weight wise, I don't think it will be that simple. Virtually everything is carbon fiber in F1 cars except for the engine and the drivetrain, maybe they can shave off about 10kg without minimum weight regulation but any significant weight saving would require ground up chassis design, without assurance of added pace. Doubt any racing team is going to ditch RWD design they have perfected over decades to try and see AWD chassis would work better. These cars have so much downforce, any advantage offered by AWD would likely be offset by clever aerodynamics with much less weight. We are talking about Ferrari guys complaining they lack top speed at 310kph vs. Mercedes W11, doubt the AWD helps much in this department either. I suppose it could work if AWD can corner 10kph higher than the rest of the group and negate parasitic loss in straights without reliability issues.

2013 is 642kg with 2.4L V8 engine, which is much lighter without MGU-H and MGU-K. 2014 is the year with V6 1.8, and the minimum weight was 691kg. From that point on, FIA regulated weight each year due to technical advancements (yes, 2020 car is faster than 2014) such as hybrid gear, tire and chassis width, addition of halo, etc.

However, none of the constructors in F1 during the Mercedes dominance brought this forth; regulations as you may know constantly change towards benefiting teams that are the least competitive. If any of the teams thought that AWD would bring significant performance gain at a given minimum weight and close the gap with the top teams, they would have brought forth the discussion. They haven't.

Suggested gaps are stock rubber for all, so PS2 for E9X, PSS for F8X, Cup 2 for GTS. Comparing stock E9X to F8X, PS2 to PSS alone >1.5 seconds. 2 seconds per track mile would be 4.4 seconds back base F8X with PSS to stock track spec GTS. There was definitely more there stock GTS, but Cup 2 gave way. Proper lap for a full stock F8X to be just 4.4 back of (even) my mark, but possible I suppose. That would put a stock F8X only about 1.5 seconds back of a Z/28 here, for example. Different tracks will yield different results, of course. And equal track tires for all changes the equation substantially.

6 piston front brakes + front brake ducts are a pretty big improvement despite all of the other weird decisions with this car

The G80 reviews are hitting all the youtube channels right about now. I am horrified by the ugly wheels of BMW M cars. Every single one of them including the F80 generation wheels are ugly as hell. Straight up butt ugly - the colors, pattern, everything.
Why BMW, why?????? Why can't you design decent looking wheels. |

Have watched quite a number of reviews of the new M3 and M4, including the one from Chris Harris of course. Most journalists seem to praise the increase traction (and predictability) on the rear axle and the handling as a whole. That is even with the heavier weight of the new car.
How do you guys think the G8x will perform on track / lapping days? Will the heavier weight finally hinder the longevity? Of course, these can be speculations only. We can only find out later when a fast driver gets to lap 2 comparatively equipped F8x and G8x at the same track under the same conditions.

As far as track capability, just a hot lap doesn't count. Somebody needs to flog it for 5 20~30mins sessions. That will begin to show the true colors of the car as a track toy.

Apparent major gains in rear traction could encourage a return to standard square track setup, a la E9X 275 square. 305/30-19 square on the G8X, if they can be squeezed in. That would offset some of the costs of tracking a staggered setup with a heavier car. Add bbk, camber plates. Same stuff you have to do to an F8X and every other gen. 11.6 quarter mile, looks sub-8 seconds 100-200 kph. (Possibly faster than a GTS on the roll.) F8X was over 9 seconds? So G8X puts 1+ second on the F8X on most straights. After F8X, have zero concerns over engine cooling. Lifespan of consumables will be cut according to increased weight and pace, but it's not like F8X is a Miata. Kept hearing about the improved front axle pre-release, guess I was not expecting much improved rear traction. That changes things in terms of track potential imo. If properly equipped with the usual mods, looks like a track monster to me.

Also........
The increased track widths and improved overall platform stability should work to offset the tire wear one would typically associate with added weight, especially at novice or intermediate pace. Driving feedback suggests G8X is not just an F8X + 200 lbs. It's 10/10ths pace that's going to create a tire wear/consumables problem, but the same can be said of almost everything.

It will be an issue for the tiny amount of people within the tiny subset of trackers who really push the envelope. This is like 3 people on any given platform. For those people the additional weight is an issue for consumables. Having seen the car in person, I think it will fit something ridiculous in terms of wheels, like 11.5 square. So that will take care of the tire consumable problem, but not of the brakes. |

Pretty shocked by the rear traction they were apparently able to build in. Not what I expected. You going for it? Comp?

I love how the believers (cough SYT and Formula above cough) will fill-in the blanks and make up for a lack of facts with optimistic conclusive statements like "this wont be a problem, tire wear will be manageable, I can stuff a 425 tire in there, that will be great, etc." You have no idea till you get your hands on a car AND have at least a dozen track days on it, so chill a bit would you?
I also love how the haters (cough existing F80 owners who cannot afford to upgrade right away cough) will proclaim negative conclusions. I'm right in the middle. I will wait till regular people like me to get their hands on the car in significant enough numbers and have enough seat time around a track to see how it behaves. That is the only reliable data. Other than known universal laws of physics such as weight is bad when going around corners. You don't see too many M5s as track day cars. There is a blindingly obvious reason why.
