Feature Showdown
Both come with modern infotainment systems.
The BMW M3 counters with wireless Apple CarPlay/Android Auto, panoramic roof, ventilated seats, power tailgate, Harman Kardon audio and ambient lighting. Which feature set matters more depends on your daily routine and priorities.
Drivetrain
The Citroen C6 uses a 3.0i V6 Petrol producing 160kW and 290Nm of torque, sent through a six speed automatic to the wheels. It covers the 0-100km/h sprint in 9.4 seconds.
The BMW M3 responds with a Petrol making 353kW and 550Nm, paired to a manual driving the rear wheels. It gets to 100km/h in 4.2 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 Citroen C6 measures 4,908mm long on a 2,900mm wheelbase, 107mm longer than the BMW M3 at 4,801mm (2,857mm wheelbase). The longer wheelbase on the Citroen C6 generally means more rear legroom.
Boot space is 488L in the Citroen C6 and 480L in the BMW M3, giving the Citroen C6 a 8L advantage.
For towing, the BMW M3 leads with a 1,800kg braked capacity vs 1,400kg. That 400kg difference matters if you regularly hitch up.
