1991 Bentley Turbo R

• The 1991 Bentley Turbo R features a 6.75-litre turbocharged V8 producing an estimated 340 PS (250 kW) and around 700 Nm (516 lb-ft) of torque, tailored for refined performance.

• Its chassis enhancements include a 50 % increase in roll stiffness, stiffer anti-roll bars (100% front, 60% rear) and cast alloy Ronal wheels with Pirelli P7 tyres — key steps in improved road-holding.

• Positioned as Bentley’s luxury saloon with sports capability, it bridged grand tourer comfort and higher speed handling, offering buyers a distinct alternative to other luxury marques.

Design and Exterior Presence

The 1991 Bentley Turbo R retains the long, elegant body of Bentley’s SZ-era architecture. With a length of 5,268 mm (207.4 in) and a width of 1,887 mm (74.3 in) the proportions remain stately yet purposeful. The wheelbase of 3,061 mm (120.5 in) provides a spacious cabin, while body surfaces kept the classic Bentley cues: crisp edges, tall greenhouse and subtle detailing.

Up front the radiator shell sits body-colour, with dual round headlamps and jet washers (introduced in 1989). The stance is improved over its predecessor. The lowered gradients, cast alloy wheels and wider track give the car a more planted posture than earlier Turbos. At the rear, the subtle spoiler beneath the front bumper and steel sill extensions accentuate the ‘road-keeping’ enhancements made when the “R” designation was applied.

Powertrain and Dynamics

The Bentley Turbo R uses Bentley’s long-serving 6.75-litre (6,750 cc) V8, here turbocharged and paired with a three-speed automatic (in the European market at that time). The published specification for 1991 indicates 250 kW (~340 PS) and 700 Nm torque. These figures resulted in 0-100 km/h times approximately 8 seconds — precise test figures vary.

What sets the 1991 Bentley Turbo R apart is the chassis re-engineering. Bentley’s engineers added anti-roll bars twice as stiff at the front, 60 % stiffer at the rear, and introduced firmer dampers and a laterally anchored rear sub-frame. The result was improved lateral stability and road-holding without sacrificing ride comfort. Contemporary reviewers noted that the car could keep up with luxury sports saloons despite its size and mass.

Interior and Luxury Features

Inside the 1991 Bentley Turbo R the comfort and materials uphold Bentley’s premium standards. Full leather upholstery, wood veneers, power seats and optional airbags feature in most markets. The instrumentation blends analog thrill with executive refinement: a large rev-counter and 170 mph speedometer sit alongside analog clock and temperature gauges. Additional standard equipment includes ABS brakes, and alloy wheels (Ronal) fitted with Pirelli P7 tyres helped reduce unsprung weight.

Visibility is generous, and while the interior is undeniably large, the driver-oriented layout and refined finishes give a sense of driver-car synergy. For a 1990s luxury saloon this was ahead of its time.
