F10 BMW ///M5 rumored to produce 550bhp!

[Jason]

Artist Impression:

Work on the new BMW M5 is gathering pace, industry sources have revealed to Autocar. M division is collaborating closely with the team developing the next 5-series, and plans to take the supersaloon fight to Mercedes’s doorstep with an all-new, fifth-generation 550bhp M5 in 2011. Mercedes is currently working on a ground-up redesign of the E63 that will appear in 2009.

The new 5-series, due in 2010, will be an obvious evolution of today’s design, and the new M5 is expected to use the current V10, bored out to 5.5 litres. It is also likely to get a direct injection, turbocharged unit, to reduce emissions. The engines will be available with either the six-speed manual gearbox or the new seven-speed M DCT double-clutch transmission.

Further improvements in fuel economy would result from the use of the company’s stop-start technology. BMW has already emphasised that it wants to reduce the emissions of the new 5-series through the Efficient Dynamics programme and it’s unlikely that the M5 would sidestep this technology. The part-time alternator system, for example, which is branded as regenerative braking, boosts power and economy without in any way affecting performance. - http://www.autocar.co.uk/News/NewsAr...eries/232600/#

This is what I humbly predict....

No turbos but KER....

http://www.e90post.com/forums/showthread.php?t=137771

So we have had a lot of idle speculation on the future of M cars. Given our knowledge of BMW Corporate. I think that I can put forward a reasonable theory about the next generation of M cars. This thread is for discussion purposes.....

Assumptions

• Given the emissions and fuel economy rules, BMW will not be pursuing an outright power strategy. We shouldn't expect beasts like the Audi RS6 that try to compensate for weight by adding power. We should expect the same power output from the engines or a slight power bump (i.e. 5-10%)
• One of the areas that BMW M will focus on will be weight. Weight the universal evil....it affects acceleration, handling, economy etc.... I would expect the F10 / F12 to weigh less than today's E60 / E63
• BMW M and Formula 1 will be tied at the hips for the foreseeable future. For BMW to capitalize their investment in F1, the M cars will use as much of the technology of the F1 cars as possible. It appears F1 will NOT likely adopt turbo charging but will adopt Kinetic Energy Recovery systems as early as 2009. These KER technologies would be phased in from 2009 to 2013

T-Bone's prediction of the F10 M5 and F12 M6:


Weight:

• M5 - 3800 pounds / M6 - 3500 pounds

Power:

• 550 hp from a normally aspirated V10 (call it Mark II) with more "Efficient Dynamics" technologies from engines like the N54 and N64 (minus the turbos).... direct injection, electric water pumps and new ones like cylinder shut down

Transmission:

• I think the big areas of innovation for BMW M will be materials (to control weight) and the transmission. If you read the article below....F1 will be introducing KER technologies that will seek to recover kinetic and perhaps heat energy from braking. This hybrid type of system is much different than the hybrids we see today that convert kinetic energy to electricity and then store it in a heavy battery only to convert back to kinetic energy later.
• The KER systems have to be much more efficient. They would need to be in the 80-90% efficiency range. While F1 is quite open as to how it will allow manufacturers to implement these technologies, it would make sense for BMW to integrate KER technologies into the transmission / flywheel. There are KER technologies that can be implemented at the wheels....but this would increase overall weight and more importantly, unsprung weight.
• So I predict a MDCT type of transmissions with KER technologies that will add kinetic energy into the system during acceleration to bump effective power from 550 hp to over 600 hp. Also I would expect KER technologies to allow cylinder shutdown to be more effective to vastly improve fuel economy in city environments.
• It is rumored the F1 cars will have a "boost" button to increase torque on track out....but for roadcars, BMW would automate that...probably using the throttle position modulate the torque delivery
• So the new MDCT transmission we see in the M3s is already obsolscent.

If BMW puts together such a package, we should expect to see a car that outhandles and out-acceleraters today's M5 / M6 with a 25% improvement in fuel economy.

This is my theory......thoughts? Of course, this all gets translated in to the new M3

T-Bone

how do you know so much about this stuff?

are you involved in the industry, or just an enthusiast?

[dillon733]

i know this is slightly off topic so dont flame me but... how come there is no M7 i just thought it would be cool and would be good competition for a s63/65. Any plans that any of you know of for the future bodystyle being offered in an M.

Very interesting.

LOL... This looks like something you copied and pasted from a magazine.

Just a car nut. I am not involved in the automotive industry but I am completely familar with technology and how products are developed.

Are you accusing me of something?

[Sedan_Clan]

Interesting.

[BMWPower06]

Why would BMW bore out the current V10 to 5.5L then turbocharge it only to see a bump of 50hp. I call BS

[MrHarris]

Nice post T-Bone, if you are even close with the weight estimates of the new M5/M6, then wow new respects to BMW as they haven't reduced weight in god knows how long.

Yeah, I think your right on this one T-Bone, Though BMW might still stick some small turbos on her!

We will know if I was complete off base in a few years

B7

it will have twin turbos.

I like the new headlights in the rendering.

too early to tell.. i do think they will consider twin turbos

The B7 is the ugliest modded car I have EVER seen.

I'll take an Audi S8 over that anyday.

[sayemthree]

twin turbos and no more Edna Eyes! FTW!!!!

M5 woohoo. My next victim in 2010.

[rlgoldstein]

Can you tell me how to track where my new bmw is on this site. I was last told it was awaiting a ship and I could track it on this site but I cannot figure it out. rlgoldstein
