BMW moves to 2 specific Architecture for future models.
And 1 jointly developed architecture with Toyota.
FWD Architecture Modular - UKL BMW-MINI (Available with All-Wheel Drive)
RWD Architecture Modular - BMW - Rolls-Royce (Available with All-Wheel Drive)
BMW-Toyota jointly developed RWD Architecture - BMW-Toyota-Lexus (Available with All-Wheel Drive)
The Architecture used for the next generation BMW 3er , 5er , ,7er , X models and the Rolls-Royce Ghost is modular , the Architecture is the central piece and then depending on which model the remaining sections are modular and then applied to distinguish each model whether in SAV or extended wheelbase models.
Its an intelligent approach to a shared architecture. It is in fact similar to what is used in the current 5er , 6er , 7er , X5 etc and that is why we have extended model variation in the BMW 5er Gran Turismo , BMW 6er Gran Coupe and the China only BMW 5er Li.
The intelligent part is really the introduction of the Carbon Age for core BMW models beginning with the all new 7er. On top of this architecture brings an intelligent mix of material technology which combines aluminium , magnesium and CFRP to each models structure.
The weight advantages over existing architecture is outstanding. There is a BMW i8 video you should watch because it essentially gives the game away to how BMW will bring Cost effective not Cost cutting changes to each new model , less is most definitely more especially in achieving overall weight reduction.
Upcoming Technical innovation will also be shared across each model - Advanced Head-Up Display with incorporated surround augmented reality and passenger entertainment , social facility , Autonomous driving and Self-Park, BMWs new ride refinement control and Laser Headlights to name a few.
This will be possible on even the 3er because of the single architecture.
Then there will be a shared architecture in collaboration with Toyota for a range of sportier models including the next 6er and Z models.
Again this is scalable and modular to be utilised on a range of jointly developed models between BMW and Toyota/Lexus.
The key part to this significance will be all resources will be able to be contributed between both brands and you are looking at possibly a first a full Carbon fibre tub structure in a mid-entry Roadster. This is strategically and an important area of innovation. No competitor will be able to match that in a volume product like a Z3.
Of course the cost savings will be there , but it will also allow BMW to challenge future legislation and rising costs but still develop new niches as well as extending individual model portfolios to appeal to new and existing customers.
It also brings BMW at the forefront of engineering innovation.
The first look at an exciting new future will be celebrated in the form of a new Luxury Concept car that will be unveiled in April ahead of the Auto China in Beijing.
There will be further developments with BMWi but at the moment all current concentration is on the first two BMWi models the i3 and i8 which have gone from concept to production. There will be another BMWi concept soon that will show potentially further progress and again it will be reaction that will determine its future.
The M cars are going to be in the greatest position of all. The M3 and M4 shows what was available at that time. But progress by 2016/2017 when the G30 based M5 arrives in 2017 that progress in CFRP will be much further along.
The G30 will use CFRP in its structure but M5 will follow the M3 and M4 and use it in key areas of the engineering and for the first time on the body panels.
The same follows true for the joint BMW/Toyota cars which will include the next generation BMW M6.
The joint development means that Toyota who are also an in-house producing CFRP manufacturer can combine material resources therefore allowing a range of specific models to use an intelligent material mix reserved for high end sports cars.
BMW is now the worlds largest manufacturer in producing Carbon Fibre based cars and this is due to the significant investment to build facilities and develop the process. The benefit is that it becomes entirely cost effective and allows BMW to spread the material across their whole portfolio as it becomes produced in more volume and becomes even more cost-effective.
