What to do if your 505-horsepower, 184-mph, 6.75-liter V-8 Bentley Mulsanne just doesn't seem quite sporty enough, despite hurtling the mass of the moon to 60 mph in a scant 5.1 seconds? Why, get a Mulsanne Mulliner Specification instead.

The new package, set to debut at the 2012 Geneva Motor Show, promises a sportier sensibility, coach-built luxury, and a few unique add-ons.

Two-piece, bright-finished aluminum alloy 21-inch wheels with race-derived titanium fasteners, 265/40 ZR21 tires, and a new Sport setting on the Drive Dynamics Control system all add up to enhanced performance as well as looks. The Sport setting improves body control without reducing ride comfort, according to Bentley. Other exterior tweaks include a pair of fender vents of polished stainless steel in the Flying B motif, engraved with Mulliner script, over a black matrix grille.

Inside the cabin, the Mulliner Driving Specification includes a bespoke diamond-quilted perforated leather pattern, indented leather headliner, knurled controls on door handles and air vent controls, a baseball-stitch leather gear lever, polished drilled alloy pedals, and Mulliner sill plates.

As with all Mulsannes, the Mulliner can be customized with a nearly limitless array of paint and upholstery colors, veneers, and leather types.

Along with the Mulliner, Bentley is introducing two new features available on all Mulsannes: a bottle cooler and a sunroof.

The bottle cooler is located in the rear, and includes a storage area for two full-size champagne bottles, plus three hand-blown, hand-cut lead-crystal champagne flutes from the bench of designer David Redman. The flutes are cut to mirror the Mulsanne's 21-inch five-spoke sport wheel.

There are even bespoke chrome flute holders in the center seat cushion should you need to rest your champagne momentarily. Perhaps to open the sunroof.

The sunroof offers standard tilt/sliding functionality, with its large opening and tinted glass offering a range of exposures. A color-matched blind--made of Alcantara--seals the sunroof off to provide complete shade when desired.
