AVUS and TELESTO: Limited editions of the BMW M3 and M4 for Belgium and Luxembourg

With three strictly limited special models based on the BMW M3 and M4, dealers in Belgium and Luxembourg attract new customers to BMW’s car dealerships. Three special cars are being offered, in the form of the BMW M3 Telesto Edition, the BMW M4 Telesto Edition and the BMW M4 Avus Edition, named after their respective individual livery. While the BMW M4 is available in both Grigio Telesto and Avus Blue, the M3 sedan is the only gray to choose from.

As the pictures from BMW Belux show, the models of the coupe are already variants of the 2017 BMW M4 Facelift. While the Telesto edition of M3 and M4 is built 20 times each, the BMW M4 Avus Edition will only be delivered to 10 customers.

As connoisseurs already recognize, the wheel are in the design star spoke 666, and all the special models are equipped with the optional Competition Package. As a result, the power of the six-turbo straight-six cylinder increases to 450 hp, but just as important are the extensive modifications to chassis, steering, electronic tuning and exhaust system.

In addition to the special individual paint finishes, the vehicles carry some tuning components from the BMW M Performance accessories range and the interior has also been thoroughly upgraded. In addition to the color matching contrast seams, an engraving in the carbon interior trim highlights the exclusivity of those models.

I absolutely love these rims!

CFRP driveshaft in the BMW M3/M4 replaced with steel

From November 2017 onwards, the CFRP driveshaft in the BMW M3 Sedan, BMW M4 Coupe and BMW M4 Convertible will be gradually replaced by an M specific driveshaft made of steel. BMW says this measure will create the necessary technical basis for meeting future statutory emissions requirements. At a later point in time, a petrol particulate filter (PPF) will be incorporated into the existing installation space in these models in major markets.

“The newly developed steel driveshaft has been designed to ensure the superlative performance and handling qualities of the BMW M3/M4 high-performance sports cars remain unaffected,” BMW says in a press release.

For production-related reasons, this pre-enabling needs to be carried out universally for the BMW M3 Sedan, BMW M4 Coupe and BMW M4 Convertible. This measure does not apply to the BMW M4 CS and BMW M4 GTS special-edition models.

So why do they replace the CFRP driveshaft with steel ones?

But then why will they leave the CFRP driveshaft for the CS? Maybe it will be out of production when the time for the PPF comes

 

[SCOTT27]

The M3 exits next year and the M4 in early 2020. So the M4 is still required to offset emissions regulation.

Oh please.

What does the driveshaft have to do with the emissions?

If anything, the lighter CFRP one helps reduce emissions!

 

[DjordjeC63]

Actually it reduces emissions...of money.

 

[CrunchSlaughtered]

Maybe the steel one is with smaller diameter, so more space is ensured (just supposing)

I meant that the CS will be out of production, not the M4

Yep, lower drivershaft mass, less parasitic losses, less emission. I have no idea what they are talking about

 

[Matski]

Packaging, or so it seems.

The CFRP shaft is one long straight piece with a uniform diameter. The shaft in a 440i (for example) is a two piece, smaller overall girth in places, and has a UJ in the middle which surely allows for better packaging options. Add to that, that the CFRP driveshaft apparently has additional metal cladding to protect it's weave from road debris, which must take up some additional space.

If they need to fit a PPF in the existing transmission tunnel, I'm sure moving back to a two piece steel shaft gives them more room to play with.

It does appear to be an odd move to make the change without actually having the PPF installed though - it seems they've decided the ability to offer a relatively quick and easy PPF retrofit is perhaps quite important.

I can understand the need for more space.

Everything else sounds like cheap excuses dressed with nice words.

 

[manuelf]

Matski is spot on! Have you ever had a look under the chassis of an F8x? With the exhaust system and the huge diameter cfk driveshaft, there is literally no place left to fit a particle filter to the exhaust system. And be sure: Reengineering to a steel driveshaft costs much more than simply producing the cfrp driveshaft for the remaining lifetime... but as legislative here is going frenzy right now regarding emissions, there is no way out for BMW but coming up with this ugly compromise ... (I'm so happy, that mine has come still with cfrp driveshaft )

Be careful out on the streets. It's unfortunate that these often end up in the hands of uncapable drivers.

In the NYC area, lots of wealthy kids get M3s/M4s as their first car... and they tend to drive like they're possessed, which means a high amount of M3/M4 accidents.

That is a big hit, hope the passengers survived.

 

[Zafiro]

Same problem with young people and their first motorcycle. They just dont have the skills yet.

 

[Laurent T]

Ouch, "lateral pole" style impact. That's bad...
