Now that much tech specs for the F80 M3 / F82 M4 have been revealed, do you perceive the M3 any differently when seeing it in action?

We can finally be sure that what we are seeing and hearing is an M3 powered by its 3.0L bi-turbo inline 6 S55 engine outputting approximately 430 hp, far beyond 369 lb-ft, and to a redline just north of 7500 RPM.

Here is the F80 M3 prototype continuing some final testing on the Nurburgring ahead of its January debut at the Detroit auto show. Order banks should open in January-February 2014, followed by production in the Spring and deliveries by late Spring – early Summer.

We have both good and bad news on Active Sound technology in the M3/M4. For those unfamiliar, Active Sound technology was first introduced in the M5/M6 and has extended to other models such as the M135i. The system modulates existing frequencies, which are played over the stereo speakers at varying sound levels based on throttle input, speed, and engine revs, as well driving the mode (louder in Sport and Sport+ settings). See BMW’s original press release on this.

So, the bad news is yes, the M3/M4 does feature Active Sound.

But, the good news is that we’ve confirmed with BMW Germany that it’s a live amplification of the S55 engine’s natural sounds. There is no artificially generated sound or pre-recorded track being played. This sound amplification takes … CONTINUED

Now that the M3 M4 technology day has come and gone, with access being granted to the press for the first time, BMW has released a slew of official track video footage of the prototypes. And since these are officially released videos, they feature some of the best quality video and audio yet of the F80 M3 / F82 M4.

For all the videos that have come about from the recent M3/M4 technology day, check the Videos section of our Tech Guide thread.

We’ve now had confirmation of the s55 engine’s sightly above 7500 RPM redline via the official released specs, but seeing as how the tachometer and redline were ever elusive all these months and years of spy photos, we’re happy to finally share with you images of the M3/M4′s redline.

Though the actual redline starts at the 7500 mark, expect the rev limiter to kick in a bit after that.

You’ve already seen the M3/M4 technical presentation slides in our Official Tech Guide Thread. Now view the presentation as it was meant to be digested – in animated form.

Who doesn’t like fancy 360 degree rotating views and animated technical blow-ups… we definitely do.

Today’s tests at the Nurburgring were stopped by a BMW F80 M3 crash ten minutes before the end of the session. The accident occurred at a section called “Metzgesfeld” where the driver lost control and crashed into the right guide rail.

Fortunately, the test driver is OK and was only fitted with a neck collar. The F80 M3 prototype was transported back to the BMW technical center at the Ring.

Unfortunate that this happened, but it gives us more looks at the advanced M3 and M4 prototypes and a peek at what appears to one-piece sports seats, different than the ones in the prototype M3/M4 we rode in recently (compare).

Could these one-piece seats also possibly have carbon fiber backs as the ones which appeared in this earlier … CONTINUED

We’ve shared with you the M3/M4 official specs and our ride-along/workshop notes, now have an on board look as we ride with Bruno Spengler in the M4 prototype at BMW’s proving grounds near Munich.

Bruno shares his thoughts on the EPS (electric power steering), turbos, transmission and testing on the Nurburgring.

And if you’re wondering whether the in-cabin sounds you hear are artificially enhanced via Active Sound, we asked and were told by one of the BMW engineers that there was absolutely no artificial sound feature. But, other outlets have written that the M3/M4 will use the speakers to amplify the sound, so we have contradictory info. A request for clarification is in at BMW and we should have an answer soon.

BIMMERPOST correspondent Jens Meiners just spent a day at BMW’s testing center near Munich for the BMW M3/M4 workshops and ride-along. Here is our report:

Thanks, BMW, for the earth-hugging i3 and the i8, but what enthusiasts really care about is the next M3 – and its two-door variation, the M4. Production of the current one has ended in July, while the next models won’t go into production before Spring. Why the gap? We hear that BMW has essentially run out of parts to build them.

It means the end of an era: The E90 M3 was fitted with the last naturally aspirated BMW M engine – and it was also the last BMW M to use a dedicated M engine developed from scratch. No more. Despite … CONTINUED
