Ya it was sort of associated with a 335tii article...but I think it is WAY too early to be speculating on the new 3 series....and I thought it looked more along the lines as some of the other 5 series renderings so I posted it here.

woah that PS looks stunning! I think it's time that German cars make steps forward like this soon... the overall shape have been pretty consistent over the last 2 generations... it's time to use the CS lines on production!

That Illustration although not exact is closer to the F10 5er than it is to the still a work-in-progress 3er.
The Air Intakes and the angle of the headlights - a similar appearance to today's 5er headlights are surrounded by a squarer -CS Konzept twin kidney grille and not as great height as the 7er grille.

That photoshop rendering looks class. BMW take note.

New M5 according to Autocar
Autocar - New BMW M5 in 2011

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.

So a re-cap of what this thing might end up looking like:

some combination of these images?

I expect a desing similar to the autocar one, with that front end, and a more prominent and squarish kidney grille than the F01 one.

AutoCar or the Ignition PS will be a perfect replacement for my 3 series.

Some of those chops are too weird. I think we already know that we should rule out a totally new design because the new 5er will be evolutionary rather than revolutionary in design.

Yes, doubt they will carry all those design cues from the CS, i just don't realise they will do anything that radical... as can see with the F01 7series, it got pretty much nothing from the CS apart from those bigger grilles and perhaps the tail light graphics, judging by that, i think the MotorAuthority (blue car) chop might probably be the most accurate, even I hope they do something like the Autocar chop.
