The spy shots suggest the styling tweaks for the facelifted car will be subtle, with a revised grille and air intakes. Black cladding partially obscures the new LED headlights, while the redesigned fascia creates a smoother overall shape, with particular focus paid to the front wings.
The bluff rear of the Mulsanne’s bootlid has also been made smoother, with minimal changes to the rear lights and bumper. The most noticeable alterations for the long-wheelbase version are the elongated rear doors and extended glasshouse.
The twin-turbocharged 6.75-litre V8 engine, which was completely refreshed for the Mulsanne when it was launched in 2010, is expected to remain unchanged, with 505bhp and 752lb ft of torque. Bentley remains tight-lipped on details about the facelift, but with a hybrid Bentayga SUV already confirmed for production, a hybrid powertrain is likely to appear in the Mulsanne too, as previewed in 2014 in the Mulsanne-based Bentley Hybrid Concept.
The facelifted Mulsanne range is tipped to be followed by revised versions of the Brooklands coupé and Azure convertible, along with a production version of the Bentley Grand Convertible concept revealed at last year’s Los Angeles motor show.
