CAR Magazine has posted their speculations on the next generation G80 M3. Here are the highlights:
S58 engine
Power output will equal the M4 GTS (493 HP / 442 LB-FT)
8 Speed automatic (no DCT)
If manual transmission survives, will only be for rear-drive models
Water injection system from the GTS
Optional on-demand all-wheel drive
48-volt mild hybrid system
Electrically spooled turbochargers
Coasting mode in eco setting
Start/stop system will cut engine earlier
Increased use of aluminum and composite materials
50:50 weight distribution
Improved torsional stiffness
Reduced weight
Three types of seats offered: carbon fiber buckets, conventional sports seats, fully adjustable comfort seats
*No* switchable anti-roll bars, air suspension, rear-wheel steering or active aerodynamics
Future G82 M4 GTS expected
G83 M4 convertible gets fabric top
iD7 iDrive system features three interactive displays
It's still early yet and the G82 M3 / G82 M4 isn't due for a few more years, so read current speculation with a grain of salt, and of course things are always subject to change even if true today. But, there's certainly enough things on this list which are more than likely to be included in the next gen M3 and M4.
