<br />
Both wear the standard hallmarks of BMW's M division. There's a subtle power dome in the hood, along with the requisite M3/4-branded strakes on the front fenders. The front and rear fascia are more aggressive than what we've seen in the 3/4 Series M Sport package, as well. Split-five-spoke wheels mean the neither car will stand out in the family portrait and those gold calipers, meanwhile, signify what has been rumored for some time - the M3 and M4 will be getting carbon-ceramic brakes.<br />
<br />
The cabin is home to the standard suite of M accoutrements, including a new steering wheel and more heavily bolstered seats. Special trim, including carbon fiber, will be available to further set these cars apart from the standard models.<br />
<br />
We reported on the <a href="http://www.autoblog.com/2013/09/25/bmw-m3-m4-430-hp-six-speed-manual-video/">M3 and M4's powertrains back in September</a>, but as a quick refresher, both cars will use a 430-horsepower, twin-turbocharged six-cylinder with the owner's choice of a six-speed manual or a dual-clutch transmission.<br />
<br />
According to the options sheet provided by <a href="http://www.bimmerboost.com/content.php?4125-The-2014-F80-M3-leaks-early-High-resolution-pictures-and-ordering-guide"><em>BimmerBoost</em></a>, an adaptive suspension, 19-inch wheels and a head-up display will be available as optional goodies, along with a range of more traditional luxury options like heated and powered seats, a parking assistant, side and top-view cameras and LED lighting.<br />
<br />
Finally, the color palette - both cars will be available in eight colors. The M3 you see above is in <a href="http://www.autoblog.com/2013/10/29/2015-bmw-m3-caught-by-helmet-cam-video/">Yas Marina Blue Metallic</a>, while we're guessing the M4 is Austin Yellow Metallic (which reminds more than one <em>Autoblog</em> editor of the <a href="http://www.bimmerboost.com/content.php?4125-The-2014-F80-M3-leaks-early-High-resolution-pictures-and-ordering-guide">E46's Phoenix Gold</a>).<br />
