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
We share with you the first official specs and technical details of the 2014 BMW M3 (F80) and M4 (F82)!

The F82 M4 coupe and F83 M4 convertible continue testing and we continue sharing pics with you.
Once it’s fully revealed, we will see an M4 convertible which shares the M4 coupe’s styling (and mechanicals), save for the roofline and trunkline. To give you an idea for how the M4 convertible will look once all the camo comes off, check out our production M4 renders below.
The one clear difference is that the M4 convertible features a different roof — in the form of a non-carbon fiber folding hardtop. It will operate and fold in the same manner we’re used to seeing on the E93 M3 convertible.
As for the M4 coupe, we have all effectively seen the production M4 in the form of the M4 Concept (minus … CONTINUED
Last year, Mr. Ludwig Willisch, President and CEO of BMW of North America, confirmed to us an inline 6 cylinder engine for the upcoming M3/M4, and we showed you spy photos of the engine. Despite these confirmations, stubborn rumors pop up periodically regarding a potential V6 configuration for the upcoming s55 engine.
If you needed any further convincing, now hear it from the BMW NA CEO himself (again). Speaking at an event that we are currently attending for the launch of the new X5 and 4 Series, Mr. Willisch references an inline engine for the M4 (and hence, M3), confirming he’s really happy that “it is going to be a car that has the cylinders in one line.” How would Mr. Willisch know? He was formerly … CONTINUED
Don’t possess X-ray vision to see past all that camouflage which remains on the F83 M4 convertible prototype? No worries, we give you this digital preview.
As the spy photos and our renders show, the M4 convertible will generally share the M4 coupe and M3 sedan’s styling, and of course powerplant/drivetrain.
The biggest difference will be the M4 cabrio’s folding hardtop. Unlike the M4 and M3′s carbon fiber double-hump roof, the M4 convertible will be metal and operate and fold in the same manner we’re used to seeing on the E93 M3 convertible. We stitched together earlier spy photos for a preview video (reposted below).
The M4 convertible will debut later in 2014, after the the M4 coupe and M3 sedan have their world debuts at the Detroit … CONTINUED
We’ve heard the upcoming M3/M4 at high speeds on the Nurburgring, but haven’t had many chances to hear it accelerating from a stop. Well, here’s a good listen, as this F80 M3 prototype was spotted by BIMMERPOST member KKM3 on the Pacific Coast Highway last night.
The M3 here doesn’t accelerate to redline nor at wide open throttle, and the clip is short, but we nonetheless get a good sound preview of the car’s inline 6 cylinder S55 engine and exhaust.
Here is KKM3′s reaction to witnessing this M3 in person:
I spotted this car last night around 9pm driving north on Pacific Coast Highway in Malibu, California. I knew right away it was the new M3 and I was determined to get a good clip or … CONTINUED
So, how do you current M3 owners feel about the upcoming M4 coupe? Let us know inside.
This F83 M4 convertible spotted yesterday completes the M3/M4 trifecta … until the M4 Gran Coupe comes along that is.
As one can see, the F83 M4 will generally share the M4 coupe and M3 sedan’s aero parts (and mechanicals). Even the trunk, which is of the automatically opening variety (to store the hardtop), appears to feature a similar CSL style curve. Parts such as the front/rear bumpers and mirrors may appear different than the M4 coupe, but that’s due to the heavier camouflage which the M4 convertible still retains.
The one clear difference is that the M4 convertible features a different roof — in the form of a non-carbon fiber folding hardtop. It will operate and fold in the same manner we’re used to seeing … CONTINUED
Following the reveal of the BMW M4 Concept, testing continues on the production M4 Coupe and here we have our best look yet at the production bound F82 M4.
Spotted in Germany, this prototype looks nearly the same as the concept. The only significant differences are the absence of the concept’s carbon fiber front lip, rear diffuser fins, carbon fiber exhaust tips and black kidney grilles, which may all become available as part of the M Performance Parts catalog for the M4.
Everything else is virtually identical – the bumpers, sideskirts, mirrors, roof, rear diffuser, CSL style trunk and the hood bump. Seems like those of you who were impressed by the M4 Concept will not any letdown with the production M4 model.
Technical specs have not yet … CONTINUED
