5 Series (G30) BMW 5 Series (G30/31/32) Spy Pics & Info Discussion

SKY · Jan 9, 2015

Georg Kacher is claiming at Car Magazine the G30 will lose 80 Kg from the F10. Next M5 will lose 180 and have the same engine the M5 30 jahre has with 600 PS. No V8 but inline 6 with up to 375 PS in the 540i and 400 PS in the 550d (quad turbo).

How can the next M5 be 180 kg lighter and the normal 5er only 80 kg?

Anyways, we're looking at a 600 hp M5 below 1800 kg. Sounds pretty nice!

Just like new 4er is 25kg lighter, and M4 is 100kg lighter. More carbon.

Carbon body panels will be used on the M5 , Roof , bonnet and boot-lid . Basically the whole top level of the car , the weight load bearing structure will be used on all 5ers which is Carbon as is certain areas of the drive train and roof structure. Then combined with the standard 5er mix of aluminium , magnesium and hot pressed steel.

After having seen the G11 7er totally undisguished, this is what I expect from the G30 5er:

- Complete evolutionary design.
- Same side profile than the F10 with new door handles, thicker hoff kink, softened shoulder line where it meets the rearlights. More chrome on the lower side profile.
- More squared front end, basically I expect 90% the front end of the Autobild render.
- Thinner realights, bigger exhaust and more chrome on the rear end. I would expect Autobild rear end of the car to be 90% accurate as well.
- Same interior than the 7er, same air vents, same radio/AC controls, probably with no chrome.
- Less complex central tunnel, maybe a link between it and the central console, less trim on the door panels.

The new 7er is not what it should be. The 5er has always been the most balanced design in the BMW line up IMO. I expect this car to be better looking than the 7er, but the G11 is the car that sets the new design theme, and I have the feeling this "new" design theme won´t be as good as the current one.

The 5er begins the transition if you will of the angular edged language previewed with the Vision Future Luxury. Both the headlights and the rear lights are more squared off than rounded.
You will see something soon that is a variation of the new 5er but a preview of the more chiseled features that will be highlighted in both cars.

The X7 is full transition , there is little sculpture apart from a lower flank character-line with 7er-esque air breather in the shape of a "7" And more 7er high belt line the additional metalwork although featureless is very flared.
Although it is minimal. It is entire appropriate for the car as its outline is more of a big Touring with its sportier lower roof line at the rear.

Here you can see why the 5er is going to be a great looking car.

Nice line, as a square, I like that, but I will be cross if you are not being straight, but you hardly are.

So what you're saying is the X7 will be Vanilla #2?

I hope you don't get too bent out of shape. You have to draw the line somewhere.

Totally agree with you I don't believe they can take out so much weight out of the new car compared to the old model unless the base model has to have a similar amount of weight reduction and maybe BMW M totally engineer certain areas of the car to be much lighter than before. Changing the roof, bonnet and bootlid panels alone to CFRP won't bring a big reduction in weight compared to aluminium panels, the big weight saving will only come it they change the actual skeleton structure that attaches the panels to the body work underneath as well as the actual body on white, seat frames, suspension towers and crash structures front and back to CFRP, but that will be too expensive. They would have to design body in white to use lighter yet more stronger steels or alloys. Then the other heavy parts are engine and gearbox (can be lighter by going down to a six cylinder engine and lighter gears and internals) suspension (especially the rear suspension as it is normally mounted on a multiple welded steel sub-frame). Then design the electronic modules to be smaller and lighter, reduce the amount of wiring harnesses and connections. The problem with new cars is safety laws are making them exceedingly heavy and high, one day the car industry will have to question this necessity for over engineering of the cars structure as speed is probably the main cause for serious accidents. With increase traffic levels world wide and lower speed limits then is it really necessary to over design the cars body (massive increase in weight) for safety sakes when the assistance systems and now autonomous driving will reduce the number of accidents world wide?

Like Rolf said, I don't believe that.

If the base 5er is 80 kg lighter, there is no way the M5 will be 180 kg lighter. It doesn't work that way. You can't loose 100 kg with some body panels. Body panels don't weigh much at all. It has to be structural, and if it's structural, the regular car is just as much lighter.

170 kg for the G11, 80 kg for the G30 and 180 kg for the G30 M5? I will see it when I see it.
In the current generation F10 5er is MUCH MORE obese than F01 (relatively). G30 needs much more weight saving measurements.

Mind 7er is more expensive, they can afford to use more CFBR. 80 Kg sounds about good for any new model. It is 170 the number that is a big surprise.

Body panels is not just the core of additional weight , there will be Carbon and other lightweight materials used within the drivetrain and suspension. The majority of weight loss from the 7er comes from the weight load bearing structure in the central chassis being completely CFRP. Combine this with all fabrication of lightweight engineering and the additional body panels it adds up to around 180KG.
