We spoke very recently at length to a trusty source within BMW who is familiar with the development of the upcoming F80 M3 sedan / F82 M4 coupe and we were able to learn the following bits of news:

HORSEPOWER / TORQUE

Regarding power output, the previously estimated 450HP figure is an overestimate. Instead, expect the horsepower output to be in ballpark of the current E90/E92 M3.

What will be increased greatly however, is the torque figure. The F80/F82’s multi turbo inline 6 cylinder engine [recently exposed] will add approximately 100 lb-ft more torque over the current M3 (which outputs 295 lb-ft torque). This would put the new M3/M4 in the range of 395 lb-ft torque. There’s nothing like forced induction for thrust!

We were also glad to learn that … CONTINUED

We have been reporting and referring to the upcoming F32 and F82 models as the 4 Series Coupe and M4 Coupe for months now, and Automobile now comes in with their ruminations on what the M4 and 4 series lineup will bring. Although much of this is not new information, it provides a good review of what to expect for the upcoming 4 Series and M4:

4 Series Coupe (F32), 4 Series Convertible (F33), and Gran Coupe (F36)

• Coupe variant of F30 3 Series to be called 4 Series (positioned and priced in lineup just as the 6 Series Coupe is positioned in the 5/6 Series lineup)

• Four door “coupe” styled variant to be called 4 Series Gran Coupe … CONTINUED

Back in May we first confirmed that the F80 M3 and F82 M4 would be powered by an inline 6 cylinder turbo engine and indeed we’ve just received these first photos of the next gen M3/M4 engine, with visual proof of the inline cylinder setup.

The F80 M3 / F82 M4 will have some good cooling of the the heated air pumping from its turbos, via components such as the air-to-water/liquid intercooler unit (to the right of the engine cover) feeding the cylinders with cooled air. If this setup is anything like in the M5/M6 S63Tu engine, the air is cooled by this unit right before it reaches the cylinders. There appears to be twin intake boxes and the oil cooler bracket looks to be the same … CONTINUED

Some updated F82 M4 coupe renders from Jerry Alvarez. The white M4 coupe render now incorporates the M6/1M styled front bumper with air curtain vents recently spied on the F80 M3 sedan. Not reflected in the renders however, is an expected sleeker front fascia and headlights (compared to the F30 3 series). The F82 M4 coupe is also expected to feature a carbon fiber roof.

The F80 M3 / F82 M4 will not be constructed extensively from carbon fiber (CFRP) as some earlier reports had speculated. Because this next generation M3/M4 began development two years ago, it’s said to have been too early to take advantage of BMW’s CFRP developments with the later introduction of the BMW i cars/project. The first model (besides the i cars) … CONTINUED

Resident digital artist Jerry Alvarez has put together this speculative side render of the F82 M4 coupe.

Although not visible in these renders, you can expect the F82 M4 coupe to receive the same (or very similar) hood lip/bulge that we recently spotted for the first time on the F80 M3 sedan.

Also not reflected in the renders is an expected sleeker front fascia and headlights (compared to the F30 3 series). The F82 M4 coupe is also expected to feature a carbon fiber roof.

We have added more photos of the first F82 M4 Coupe prototype spotted last week. Full gallery inside.

It’s not official until it’s official (BMW announces it publicly), but further confirming clues that the F32 coupe will be badged as the 4 Series Coupe comes from a list of a list of forthcoming miniature scale models that BMW AG has released internally in Germany, according to BMW insider Scott26.

In addition to the new M6 models and 6 Series Gran Coupe, they identify the F34 3 Series Gran Turismo and the F32 “4 Series” Coupe as the upcoming BMW miniatures to be released.

If true, with the F32 coupe badged as a 4 Series, expect the M version to be named the M4 coupe, as per tradition for M models. The only reason this doesn’t happen is if the BMW board decides to break with BMW’s … CONTINUED

Here are some renders put together by site member E92Alpine328i (Jerry).

Our analysis:

M4 COUPE (F82)

The F82 M4 coupe render will prove to be the more accurate of the two. Most accurate is the M6 style bumper, which BMW insider Scott26 has recently said (and sketched) to be the styling to expect for the M4 coupe. The F32 4 Series coupe and F82 M4 coupe are expected to feature similar headlights to the F30 3 series, but should be sleeker/slimmer. Their kidney grilles will be also be sleeker than those seen on the render, as the recently exposed 4 Series coupe grille spy photos show.

No spy photos have yet to show a hood bulge, and the anticipated inline 6 turbo engine should fit under the bonnet without … CONTINUED

We brought you the first photos of the 2015 M4 Coupe prototype earlier today, now have a first live look and listen at the prototype in action on the Nurburgring.

What you’re seeing and hearing is the F80 M3 / F82 M4’s anticipated inline 6 cylinder engine with multiple turbochargers, pushing approximately 450 horsepowers. The engine has been rumored to be an extensively reworked and reinforced N55 6-cylinder engine with a strengthened aluminium block with a heavily modified cylinder head. The Induction technology is said to be completely new as will be the latest bi-vanos variable valve timing. But, we also think that there may be a possibility that the engine turns out to be a reworked/enhanced version of a successor engine to the N55 (which has … CONTINUED
