Yeah I've wondered this as well. I don't know if Porsche's R&D budget is THAT much bigger than BMWs but what they make simply just works. I don't know why BMW seem to find this so hard, DCT vs PDK is not even a contest.
@sq86

I know just enough engineering to be dangerous, but it seems to me that EPS is essentially an algorithm, and either the algorithm isn't accurate enough , or there is not enough processing speed to provide faster response , or potentially both.

BMWs algorithm certainly lacked feel on center, and also the feedback upon return to center was originally non existent. They have been fine tuning it for a decade and making improvements that are recognized by enthusiasts, reviewers, and casual drivers.

in the domain of EPS it's Porsche that is the best , Honda second, (Beginning with S2000) and I'm not even sure there is an honorable mention.


Is Porsche EPS BETTER than manual hydraulic feel ? Would you prefer to have sport modes of EPS vs a hydraulic rack. ? I think the answer here for most is no.


In the domain of automated transmission, once again , Porsche PDK is best , BMW DKG is a fairly distant second ... ? I'm absolutely unqualified to rank DCT transmissions so I will let others chime in here. Is the DCT transmission better than manual ? In this case , certainly many say DCT is faster, however other drivers prefer more involvement with MT. One thing that is clear however is that there is not universal agreement that the electronic transmission is superior.

In the domain of drive by wire throttle, did it ever be come preferred by drivers, or simply accepted ?


I suppose magnetic and other electronic shock. Absorber systems is another domain.... is there universal agreement that magnetic systems are Better than hydraulic ?


As we move to electrohydraulic braking systems , once again ... as with EPS.. there will be adjustable modes , but will the feel be better than a system with a brake booster ? History already is telling us an answer.
Yeah I agree with everything that you said. The engineering behind the steering geometry is really interesting to me. Car and Driver had a great article on it and how it could be improved on EPS (pretty easy to find if you search for it).

I'm just amazed that a company that advertised "the ultimate driving machine" would offer up a subpar EPS. I realize it's never going to be as good as a hydraulic system but they should be able to get it close. It makes me think they don't care about it as much. Much of it is algorithms and geometry so it should be easily "fixable."

To be honest, the reason is that BMW and most other auto manufacturers long ago outsourced a ton of their component R&D to contractors like Bosch, Borg Warner, ZF, Getrag, GKN, etc.

This is why, most of the time, innovations appear across several manufacturers at once. The EPS is designed by Bosch. BMW can probably only tweak certain parameters. The firmware is probably written by Bosch employees to BMW requirements, just like the DME.

They are dealing with the limitations of the Bosch EPS system and what they were willing to pay for at the inception of the project. I'm not sure how Porsche does it better, but it's possible they just buy more expensive parts or have paid Bosch to do more work on the software.

I'd take the pricing with a grain of salt though as that would mean a 50,000-60,000 delta with the equivalent M5.

U.S pricing will start @ around US$ 140,000 for the base M8 Coupe & US$ 147,000 for the M8 Competition Coupe.

200,000 Euros? Are they mental?

Is there an ///M button to bring back steering feel, reduced chassis weight, and bespoke ///M engines?

Looks photoshopped though.

I would bitch about this car but why would I at this point? BMW's already lost me as a customer.

Those of you who like the car though - be patient, you'll be able to get these at steep discounts fairly soon after launch

How about less modes and electronic nannies and less weight and get back to making "The Ultimate Driving Machine"
I have come to appreciate the versatility in all the modes while also being able to program the M button to anything I want and ignoring all those settings when I can. Given that the F80 weighs less than the E90 and the G20 is said to weigh less than the F80, I don't think weight is a big issue. Dimensions are. The M3 is getting too big and the M8 looks huge.
