MERCEDES-AMG is extending its product line-up with the addition of a potent new GLC 43 4MATIC Coupe.

The newcomer to the range has all the advantages of an SUV in terms of seating position, interior flexibility and also traction for the odd trip off the beaten track.

Its performance is impressive, and the GLC 43 4MATIC Coupe accelerates from rest to 62mph in just 4.9seconds and its speed is electronically governed 155mph.

It comes with a 9G-TRONIC automatic transmission, which Mercedes-AMG developers have specially configured for the new GLC to reduce shift times through the nine speed box

Power comes from the 3.0-litre V6 biturbo engine as used in other AMG Performance models. It delivers a maximum output of367bhp plus maximum torque of 520Nm.

For added agility, more neutral cornering behaviour and higher traction even when driving at speed, Mercedes engineers have designed a dedicated sports suspension on the basis of the AIR BODY CONTROL full-support multi-chamber air suspension system.

Mercedes says that during sudden changes, fast cornering, heavy acceleration or hard braking, the spring rate is automatically made harder on the front or rear axle. This effectively reduces roll and pitching while stabilising of load the vehicle.

Stand-out features of the new Coupe include a diamond style radiator grille with chrome pins and a louvre in high-gloss black with insert in high-gloss chrome and AMG lettering in high-gloss chrome.

The sporty air intakes in the AMG front apron feature fins in silver chrome and a silver chrome front splitter to direct air to the cooling modules.

No price has yet been set for the new AMG which will go on sale in December. The current GLC Coupe range costs from £40,450.
