Feature Showdown
Both come with modern infotainment systems.
The BMW M3 stands out with wireless Apple CarPlay/Android Auto, panoramic roof, ventilated seats, power tailgate, Harman Kardon audio and ambient lighting — features our data doesn't list for the Citroen C6. Which feature set matters more depends on your daily routine and priorities.
Drivetrain
The BMW M3 uses a Petrol producing 353kW and 550Nm of torque, sent through a manual to a RWD layout. It covers the 0-100km/h sprint in 4.2 seconds.
The Citroen C6 responds with a 3.0i V6 Petrol making 160kW and 290Nm, paired to a six speed automatic. It gets to 100km/h in 9.4 seconds.
The BMW M3 has the clear power advantage at 353kW vs 160kW. In the 0-100 sprint (manufacturer-claimed), the BMW M3 is 5.2s quicker. For most buyers, the way each car feels day-to-day matters more than outright acceleration.
Space & Comfort
The BMW M3 measures 4,801mm long on a 2,857mm wheelbase, 107mm shorter than the Citroen C6 at 4,908mm (2,900mm wheelbase). The longer wheelbase on the Citroen C6 generally means more rear legroom.

For towing, the BMW M3 leads with a 1,800kg braked capacity vs 1,400kg. That 400kg difference matters if you regularly hitch up.
