Bentley has unveiled three customized models that were specially commissioned to celebrate the 25th anniversary of one of their dealerships.

Dubbed the Silver Sisters, the cars are based on the Bentayga, Continental GT and Continental GT Convertible.

Created by the Mulliner coachbuilding and bespoking division, the cars are all equipped with a unique Stratos Silver paint color that has been patented by the dealership and only used on three previous occasions.

Besides the special paint job, the vehicles have an aerodynamic package which includes a front splitter, side skirt extensions and a carbon fiber rear diffuser. Other highlights include black chrome trim and 22-inch hand-polished wheels that cover gloss-black brake calipers.

The unique styling continues in the cabin as all three models have Beluga leather upholstery with contrasting Stratos Silver accents and stitching. Elsewhere, there are “25” logos on the headrests, door sill plates and Grand Black veneers.

Bentley didn’t mention performance specifications, but the Continental GT can be equipped with a twin-turbo 4.0-liter V8 or a 6.0-liter W12 engine. The former produces 542 hp (405 kW / 550 PS) and 568 lb-ft (770 Nm) of torque, while the latter develops 626 hp (467 kW / 635 PS) and 664 lb-ft (900 Nm) of torque.

The Bentayga is available with both aforementioned engines as well as a diesel and a plug-in hybrid powertrain. The latter allows the crossover to travel over 31 miles (50 km) on electricity alone.

In a statement, Bentley’s UK Regional Director said “We are delighted that Bentley Manchester is celebrating its 25th birthday with such a beautiful trio of bespoke cars, especially in the same year that Bentley celebrates its centenary.”
