The Bentley Turbo R, produced from 1985 to 1997, marked a pivotal moment in the brand’s history by fusing extravagant comfort with genuine sporting prowess. This Mk1 model transformed the perception of Bentley from a staid cruiser into a dynamic grand tourer capable of thrilling drives while cocooning passengers in unparalleled luxury.
Origins and Development of a Legend
Bentley launched the Turbo R as an evolution of the Mulsanne Turbo, introducing the ‘R’ designation to emphasize enhanced roadholding. Debuting in 1985, it addressed criticisms of earlier models being too soft and underpowered for modern tastes. Engineers retuned the venerable 6.75-liter V8 with turbocharging, paired it with wider tires on alloy wheels—a Bentley first—and stiffened the suspension for better composure.
From 1987 onward, fuel injection boosted torque further, making it even more responsive. Production totaled around 7,230 units, with the model paving the way for later variants until 1999. Motor Trend’s 1989 review hailed it as “the first Bentley in decades deserving of the famous name,” underscoring its revival of the marque’s performance heritage.
Engineering Marvel Under the Hood
At the heart lies Bentley’s iconic 6.75-liter pushrod V8, turbocharged for explosive output. Power estimates ranged from 315 to 350 horsepower, backed by massive torque around 553 lb-ft, propelling the 2.45-tonne behemoth with authority.
Early models used a three-speed GM Hydramatic automatic transmission, upgraded to four speeds from 1992 for smoother shifts and better efficiency. Rear-wheel drive was standard, with an electronic limiter capping top speed at 150 mph. Despite its thirst—expect 15 mpg urban, up to 20 on highways—the engine’s low-rev torque (cruising at 2,000 rpm at 70 mph) delivered effortless overtaking.
| Specification | Details (1985-1991) | Details (1992-1997) |
|---|---|---|
| Engine | 6.75L Turbo V8, Carbureted | 6.75L Turbo V8, Fuel-Injected |
| Power | ~315-330 hp | ~350 hp |
| Torque | ~500 lb-ft | 553 lb-ft |
| Transmission | 3-speed Auto | 4-speed Auto |
| Weight | 2,450 kg | 2,450 kg |
| Top Speed | 150 mph (limited) | 150 mph (limited) |
This table highlights key evolutions, showcasing Bentley’s commitment to refining an already potent formula.
Chassis and Handling Innovations
The Turbo R’s suspension was a revelation: self-leveling rear hydraulics shared with brakes ensured a level stance under load, while revised spring rates and dampers tamed body roll. From 1990, Active Ride Control used sensors from throttle, brakes, and accelerometers to adjust damping dynamically, firming up for spirited driving.
Wider alloy wheels and low-profile tires improved grip, making it handle more like a sports saloon than a traditional roller. Owners praised its wafting silence at speed, yet it could surge forward with poise, silencing doubters who saw Bentley as outdated.
Luxury and Interior Opulence
Step inside, and the Turbo R enveloped occupants in leather-trimmed splendor. Vast switchgear, wooden veneers, and Connolly hides created a hunting lodge ambiance. Rear space accommodated six-footers easily, with picnic tables and reclining seats for true grand touring.
- Seating: Power-adjustable front seats with heating; limo-like rear bench.
- Features: Analog gauges, climate control, premium stereo.
- Build Quality: Hand-assembled panels, double-glazed windows for hush.
- Customization: Mulliner options for bespoke touches.
At 2.5 tonnes, it felt substantial yet balanced, with acceleration belying its mass—0-60 mph in under 6 seconds.
Driving Dynamics: Power Meets Poise
Owners describe it as an “absolute joy,” with wonderful acceleration and near-silent cruising. The turbo V8’s lazy nature majors on low-end grunt, ideal for autobahns or British B-roads. Gear changes were smooth, though the early three-speed felt dated by 1990s standards.
Steering provided decent feedback, and brakes—hydraulically assisted—hauled it down confidently. It excelled as a long-distance express, immune to fatigue, yet playful when provoked. Fuel economy demanded deep pockets, but the experience justified it.
Production Variants and Legacy
The Mk1 Turbo R ran until 1997, spawning long-wheelbase (LWB) versions for extra rear legroom. It succeeded by the Turbo RT, but the original set benchmarks. Total output reflected steady demand among those seeking understated power.
Today, it symbolizes 1980s excess refined: a car where opulence met engineering ambition, influencing Bentley’s modern resurgence.
Buying and Ownership Guide
Purchasing a Turbo R rewards diligence. Values hover lower than Rolls-Royce peers, offering value for classics under £30,000 in good condition.
