The all-new M3 and M4 are, reportedly, scheduled to launch in mid-2020 as 2021 models.
This means they will offer up the same 473 HP in standard guise, a full 48 HP more than their predecessors. The new models should also be available in Competition guise from launch with a hearty 503 hp, which is identical to what the twin-turbocharged 4.0-liter V8 of the Mercedes-AMG C63 delivers.
One key difference between how the M3/M4 and X3 M/X4 M perform is set to be how they send their power to the pavement. The new high-performance SUV models come with an all-wheel drive system just like the current M5 but cannot be driven in rear-wheel drive mode like they the M5. According to some reports, the M3 and M4 will be sold in base form with rear-wheel drive but, should customers wish to send power to the ground in an easier-to-control manner, all-wheel drive will be offered as an option.
The M3 and M4 should also differ from most other current BMW M models as they will arrive as standard with six-speed manual transmissions and a seven-speed dual-clutch automatic as an optional extra.
A key change is also set to be made for the new M4 Convertible: according to Car and Driver. it will ditch the heavy retractable hardtop in favor of a simpler, and much lighter, power-operated soft top.
