Most Powerful Mulsanne Ever – The Mulsanne Speed is powered by a 6.75-liter twin-turbocharged V8, producing 530 hp (537 PS) and a massive 1,100 Nm (811 lb-ft) of torque, making it the most powerful version of the Mulsanne.
0-100 km/h in Just 4.9 Seconds – Despite its 2.7-ton weight, the Mulsanne Speed accelerates from 0-100 km/h (0-62 mph) in just 4.9 seconds, proving that luxury and performance can coexist.
Top Speed of 305 km/h (190 mph) – It is one of the fastest ultra-luxury sedans in the world, capable of reaching 305 km/h (190 mph), outperforming many sports cars.
One of the Last Hand-Built Bentleys – The Mulsanne Speed was handcrafted in Crewe, England, taking over 400 hours to build, ensuring the highest level of craftsmanship and attention to detail.
Exclusive ‘Sport’ Mode – Unlike the standard Mulsanne, the Speed model features a dedicated ‘Sport’ driving mode, sharpening throttle response, adjusting the 8-speed automatic gearbox, and stiffening the suspension for a more dynamic experience.
Unique Darkened Exterior Details – The Mulsanne Speed stands out with dark-tinted chrome accents, including the grille, headlights, and tailpipes, giving it a more aggressive, sophisticated look compared to the standard Mulsanne.
Luxurious, Customizable Interior – The interior features diamond-quilted leather seats, knurled metal switchgear, a hand-stitched steering wheel, and over 24 color options, ensuring each Mulsanne Speed is unique to its owner.
Longest Production V8 in Automotive History – The 6.75L V8 engine in the Mulsanne Speed traces its origins back to 1959, making it one of the longest-running continuously produced V8 engines in history.
Discontinued in 2020 – Bentley ended Mulsanne production in 2020, marking the end of Bentley’s flagship V8-powered luxury sedan, with no direct replacement announced.
Final Edition: Mulsanne 6.75 Edition by Mulliner – To commemorate the end of production, Bentley created the Mulsanne 6.75 Edition, featuring unique engine-numbered plaques, silver badging, and custom interior detailing, making it one of the rarest Mulsannes ever.

The Mulsanne Speed is the ultimate 12-cylinder luxury barge, combining a 6.75L twin-turbo V8 (537hp) with handcrafted Mulliner interiors and unmatched presence.
With production ended in 2020, it’s now a depreciation-proof collector’s piece.
