Bimmerpost published an early ordering guide for the pair. The list of options will reportedly be sent to dealers so they can order demo cars, so there aren't any prices. but it does provide a preview of how the cars' various options will be packaged.
Options we were already expecting to see on the M3 and M4 include M Adaptive Suspension, carbon-ceramic brakes, and the choice of a manual transmission or M Double-Clutch unit.
Proving that M has come a long way from the race-bred E30 M3, the 2014 M3 and M4 will also be offered with a suite of electronic driver aids, including Lane Departure Warning with Collision Mitigation.
M fans who can't wait for the cars' on-sale date can also start thinking about color choices. While there are two shades of white available, the gold Aurum Dust hue from the M4 concept isn't an option, and neither is any shade of red.
Regardless of what color they are, all BMW M3s and M4s will be powered by a turbocharged inline-six, producing approximately 430 horsepower and 369 pound-feet of torque. That means it will be more powerful than the previous M3's V-8 and, according to BMW, more fuel-efficient.
The new cars should also be lighter than their predecessors. BMW says the 2014 M4 will weigh roughly 175 pounds less than a comparably-equipped E92 M3 coupe.
