Characteristics and peculiarities

Backgrounds of this model
- The Bentley Mulsanne LWB (Long wheelbase) is the successor of the Bentley T2 LWB.
- The Bentley Mulsanne LWB was not available on the American, Canadian and Japanese markets until model year 1981, just like the Bentley Mulsanne.
- The Bentley Mulsanne LWB could already be bought in 1980 but no one did. The first car was sold in model year 1981.

Original characteristics
- The Bentley Mulsanne LWB has the same specifications as the Mulsanne but is lengthened by 4 inch (10 centimeter) compared to the Mulsanne.
- The Mulsanne LWB has Bentley-badges on the C-style and hub caps in Corniche-style.
- The extra length is completely available for the rear passengers. The rear doors are 4 inches longer.
- The Mulsanne LWB could be ordered with a division.
- The Mulsanne LWB has the same engine and gear box as the Bentley T2 LWB: a 6750 cc V8 engine without turbo with a three speed automatic gear box (GM400) and carburetters (Japanese cars fuel injection). The maximum power is 198,5 bhp at 3800 rpm.
- The Mulsanne LWB has a radiator grille with vanes of polished stainless steel.
- The grille is 1 inch lower and 2,5 inch wider than the one of the Bentley T2 LWB. The material is polished stainless steel.
- A curved and deeper front bumper as a result of the deeper Bentley grille. The curved appearance of the front bumper added 1.6 inches to the car's overall length.
- Opposite to the Bentley T2 LWB no winged B on the grille anymore, because it couldn't disappear in the radiator shell at impact. The winged B was loosely delivered.
- The bonnet of the Mulsanne LWB has the same pressing as the one of the Silver Spirit. That was not the case for the Silver Shadow and Bentley T.
- The Mulsanne LWB has rectangular head lamps with twin lamps.
- Until 1985 the head lamps were provided with a wash/wipe headlamps cleaning system.
- The back seats have a styling of two separate seats instead of a bench.
- Cars with a carburetter have two spread out exhaust pipes. Cars with an injection system (American market) have a single exhaust.
- The Mulsanne LWB has mineral fluid (HSMO, also called LHM) in the hydraulic system.
- The floor panel is the same as the basic floorpan of the Bentley T2 LWB.

Model year 1981
- The Mulsanne LWB was not available on the American, Canadian and Japanese markets until model year 1981. American models have separate twin rectangular sealed beam headlamps without cover. These lamps have no wash and wipe facility.
- American models have energy absorbing bumpers (which make the car a bit longer), no airdam and no fog lamps.
- American, Canadian and Japanese cars are provided with fuel injection.

Model year 1985
- The head lamp wipers are replaced by high pressure jet washers.
- Changes to the dashboard.

Model year 1986
- From 1980 up to and including 1985 the grille was inch higher than the bonnet. From model year 1986 that problem was settled.
- From model year 1986 the Mulsanne LWB gets new stainless steel wheel trims.
- The number plate is fitted on the bumper instead of below it.
- Standard with a cellphone housed within the front central arm rest.
- Australian cars are fitted with standard fuel injection.

Model year 1987, from number 20001 on
- Standard fuel injection.
- Restyled seats with increased lateral support and fully-adjustable head restraints inside the passengers compartment. Electrical operation of the seat squab.
- Electric front seat adjustment, linked to an electronic memory device with four preferred positions for both driver and passenger; mirror positions are logged in the memory system.
- Bosch anti-locking brakes on all cars except for the NA market.
- Hard suspension, like the Turbo R.
- One-piece airdam.
- Changes to the dashboard and centre console.
- From number 20240 on in model year 1987 the Mulsanne LWB was fitted with a catalyst, but could also be specified without it.
