What will they cost?
Running costs won’t be cheap, whichever car you choose, but again the M4 has the advantage, because it holds onto more of its value over three years, offers better real-world fuel economy and is cheaper to insure.
The M4’s more favourable CO2 emissions mean it’s also the cheaper of the two for Benefit-in-Kind tax, although few people will be permitted to run either of these coupés as their company car.
Standard equipment is as generous as you’d expect. Both cars get alloy wheels, climate control, electric windows, heated and electrically adjustable leather seats, front and rear parking sensors, satellite-navigation, a DAB radio, xenon headlights and Bluetooth as standard.
Safety and security kit is reasonable, with a tyre pressure-monitoring system, an alarm and engine immobiliser standard on both cars. The RC-F has more airbags (eight vs six), but isn’t available with autonomous emergency braking, whereas you can add this important safety feature to the M4.
