Bentley on Thursday said the Beluga specification gives the Flying Spur a "more athletic stance."
Details include 20-inch Black and Bright machined alloy wheels, a glass black radiator matrix and a body-colored lower grille bar.
The cabin gets piano-black veneer trim, knurled gearshift paddles, contrast stitching on the seats and steering wheel, and deep-pile floor mats.
A Bentley spokesman did not respond immediately to a query from Edmunds asking about pricing.
A Beluga is a small, white-toothed whale and also a type of caviar obtained from the Beluga sturgeon.
Edmunds says: Bentley adds a new options package to the Flying Spur that will give the luxury sedan even more visual appeal.
