Both models feature BMW's 4.4-litre V8 engine with a power output of 245kW and it has 450Nm of torque.
The 6 Series range comes with three transmission options - a six-speed manual, a six-speed auto with Steptronic and BMW's specialised Sequential Manual Gearbox (SMG).
Like the 7 and 5 Series models the 6 Series is also equipped with BMW's much-criticised iDrive system.
