Based on the same CLAR platform as the 5- and-7-series and measuring 5 091 mm in overall length with a wheelbase of 3 070 mm, height of 1 538 mm and width of 1 902 mm, the 6-series GT is both longer and lower than the model it replaces, yet weighs in at 150 kg less thanks to extensive use of aluminium and high strength steel.
The gain in length has translated into a 110-litre increase in boot space with BMW claiming a total luggage capacity of 600-litres with the rear seat up, and 1 800-litres with the rear bench folded down, 100-litres up on the 5-series GT. Available as an option, the rear backrest can also be lowered electronically.
Underneath the skin, the 6-series GT comes fitted with self-levelling rear air suspension as standard, although BMW's Adaptive setup, which adds Dynamic Damper Control, can be had as an option. Inside, the interior takes after the 5-series with the familiar 10.25-inch iDrive infotainment display featuring Gesture Control and BMW Connected Drive, while a new colour Heads-Up Display with better resolution can be specified.
In terms of driver assistance systems, the 6-series GT features a revised version of BMW's Active Cruise Control system now incorporating Stop & Go, Lane Change Assist, Remote Control Parking, Lane Departure Warning and Lane Change Warning.
Up front, the 6-series GT will available with a choice of two 3.0-litre six-cylinder engines, which in 640i guise develops 250 kW and 450 Nm of torque, and 195 kW and 620 Nm in 630d form. A ZF-sourced eight-speed Steptronic gearbox is standard on both models, although in the case of the petrol, power is routed to all four wheels via BMW's xDrive all-wheel drive system. While no top speed figures were provided, the 640i xDrive will complete the 0-100 km/h dash in 5.3 seconds and the 630d in 6.1 seconds.
Pricing starts at R1 081 300 for the 630d sans options, while the 640i xDrive retails for R1 114 800.
