Rumor: BMW M3 to Receive Six Cylinder Turbo - 1 Series M is a go

 Rumor: BMW M3 to Receive Six Cylinder Turbo - 1 Series M is a go
Bimmerfest East 2003 - E30 M3

It has been confirmed that BMW will be using a smaller turbo engine for the 2013 M3. Motor Trend says it spoke to BMW's M Division CEO Ludwig Willisch and he confirmed the upcoming ditching of the current V8 format. The naturally-aspirated 4.0-litre V8 produces 309kW (420hp) and 400Nm of torque. Previous generation M3s used four and six-cylinder motors.

The report states that a new six-cylinder will be employed but it won't be the same 3.0-litre twin turbo that is used in the 135i and 335i models. What might miff M traditionalists is not a forcefed M3, but the fact that BMW is toying with the idea of a V6 for the M3. A V6 would be more compact as opposed to the traditional inline six BMW is known to strictly use. The new engine might not even be more powerful than the V8 but the car itself would be light in order to counter this power handicap.

The segment will get very interesting as Mercedes-Benz also prepares a new 3.5-litre twin turbo V6 for some of its AMGs and Audi is rumoured to have already forcefed the upcoming RS4 and RS5.

More news on the M front is that a 1 Series-based high-performance car was also confirmed. Thought to be developed by the M guys, BMW will probably not call it an M1. It will also have a compact four-cylinder petrol engine with well over 300hp (221kW).

Finally speculation is that the M5 is about to get its cylinders cut too in order to meet stringent emissions laws and fuel economy standards. The M5 and M6 may end up with a twin turbo V8 motor displacing less than 5.0-litres.

WOW!!! All these cut backs on engine sizes. The beginning of the end for the automotive performance sector is upon us.

good for them!!! lighter cars with probably the same if not better hp to weight ratios amen BMW is the best

i agree tootall, everyone is downsizing but not everyone, mass car manufacturers. apparently all expensive car sales are still healthy but i presume those cars are being used less. i also feel probably the m3 is feeling the pinch from the gt-r and it will be too expensive to compete with an NA engine although an NA engine is much more provocatively sensual to drive on a similar output.

"The report states that a new six-cylinder will be employed but it is not the same 3.0-litre twin turbo that is used in the 135i and 335i ranges. Two turbos are likely to be fitted instead of just one." The current 3.0 liter turbo of BMW (135i, 335i etc) is actually a twin-turbo. http://www.worldcarfans.com/2060705.006/4

Sorry, missed the "twin-turbo" part in the article. I think BMW will most likely give the M twin-turbos. I believe this is also one of the reasons why their new "standard" turbo engines have minimal or no turbo-lag.

Don't worry AG4, it's still a horribly framed sequence of sentences. WCF needs a subeditor - I'd be happy to oblige. ;)

A V-6 in a BMW?! TRAGIC! Stick with the inline 6 configuation!

i doubt the v6 part but i think the new X5/X6 M engine that boasts 550+hp will be reused or similar setup but a v6.

I think to focus on lighter cars is the way forward, v8s are sweet and so are iron blocked straight sixes, but the weight of performance cars now (AMGs and Ms) affect the ride quality resulting in super stiff suspension, its about time people get comfort, speed and economy from the top models. Modern trannies will also make up for the power deficit big time.

thats nothing new. There are informations on the net that all of the M engines will in future be based on the regular BMW enginges, but will be equipped with different setups (like turbos and so on).

Very sad news. I hope the twin-turbo setup will move from parallel twin-turbo used in current x35i to the "variable" twin-turbo already in use on the x35d (small + big sequential twin-turbo). It won't make them M engines though: M doesn't mean as powerful as possible but exciting with high-revving N/A engines.

I don't see why this is sad news. We all know how special BMW motors are, but tradition cannot stop forward thinking about design and engineering. Traditionally I am a Mercedes guy, but I love BMW's philosophy (as well as Porsche) of making smaller displacement engines that rev like crazy and achieve 100hp/liter and higher. The only thing they will have to contend with from Mercedes is the torque figures, which Mercedes usually stomps everyone with. I look forward to BMW's and Mercedes' motors born from their new philosophy. Give them both a few years and I bet we will see some astonishing performance figures.

If they put a turbo setup into the M3 i would guess it wouldn't be Twin-turbo but bi-turbo instead. Even with variable flow turbos they have a limited range, if they want 20-25psi without lag it would have to be 2 different size variable turbos. There are people out there that have turbo M3s with the Inline 6 running 32psi of boost and hitting 730whp, there is lots of room for power out of the old 3.2L I6.

It would be nice to go back to the traditional Inlin6 with an iron block single VNT turbo w/decent compression (10.5:1cr), run full dry-sump, & Cylinder head with Direct injection. And add dual VANOS with variable lift..ala Porsche Variocam plus.

If (my beloved) BMW even does the R&D on a V-6 engine, I will officially cancel my lifetime fan-status, I've stuck with you through all the changes, BMW, but a V-6 would be absolutely, totally, unforgivable. What's next, front-wheel drive? It'd probably be a sweet V-6 though.
