Бентли Turbo R: Жоғары өнімділік және эволюциясы

The Bentley Turbo R is a high performance automobile which was produced by Bentley Motors Limited from 1985 to 1999. The "R" stood for "roadholding", to set it apart from its predecessor. It initially inherited the turbocharged engine from the Mulsanne Turbo and also sported a retuned suspension and wider tyres on aluminium alloy wheels, a first for a Bentley. From the 1987 model year (20,000 series chassis numbers), however, the Turbo R's V8 engine was retuned with fuel injection for added torque. Motor Trend called the Turbo R "the first Bentley in decades deserving of the famous name" in their review of the car on its introduction to the United States in 1989.

The suspension changes, though seemingly subtle, transformed the soft and less than well controlled ride of the Mulsanne Turbo into that of a real performer. Development on improving handling had already begun when Mike Dunn was appointed engineering director in Crewe in February 1983, but instead of the proposed ten per cent increase in roll stiffness, he demanded 50%. This goal was met by upping the anti roll bar rates by 100 per cent in front and 60 per cent in the rear, and by increasing the damping. A panhard rod to anchor the rear sub frame was also introduced, reducing side to side movement in corners. Around the turn of the year between 1991 and 1992, GM's 4L80 E four speed automatic transmission replaced the long running three speed Turbo Hydramatic 400 throughout the Bentley/Rolls Royce lineup, including the Turbo R.

A "New" Turbo R model was introduced in 1993 for the 1994 model year. Changes included Zytek fuel injection and appearance modifications. There was also a special version for the German market, the "Turbo R Sport", which featured the Continental T's sporty alloys and carbon fibre, rather than walnut, panels inside.

In 1995, the Bentley Turbo S was announced as a strictly limited model, with envisaged production as fewer than 100 units. Effectively a stop gap model before the introduction of the Bentley Arnage, just 60 units were produced making it the rarest of the Bentley SZ Series of cars, distributed across selected European, Middle Eastern and Asian markets and customers only. The engine termed a Blackpool version used Bosch Motronic fuel injection and digital ignition derived from Formula 1 technology, and with a larger exhaust driven Garrett AirResearch turbocharger with intercooler. It had a power output of The Blackpool engine was also fitted to twelve Bentley Continental S, and to three special build Rolls Royce Silver Spirit S. The car was fitted with a viscous differential, and with both new 255/55WR17 tyres and traction control fitted, permitted a top speed of
In 1996 production of the short wheelbase Turbo R ended, leaving only the model hitherto sold as the Turbo RL now known simply as the Turbo R. For 1998, the Turbo R was replaced by the sportier yet Turbo RT. The Bentley Turbo RT Mulliner: The Mulliner version, available only by special order for the 1998 model year, was even more exclusive and expensive. It boasts a engine with a torque output of 634 lbft (861 Nm): this was achieved by developing a new compressor for the turbocharger, remapping the engine management system, and modifying the air intake system. Visually, Mulliners have more aerodynamic, rounded bumpers with prominent venting and often foglamps, as well as flared wings to accommodate the wider track and larger 18 inch alloy wheels, sitting on low profile 255/55 tyres. Each car was built to individual specifications, with many sporting side and bonnet vents and also the smaller Mulliner rear windscreen. One popular feature in Mulliners is a prominent speedometer for the rear passengers. Just 56 Mulliner editions were built (all in 1998), of which 17 are right hand drive. Seven of the Mulliner editions built are to standard wheelbase specifications, and 49 are on the lengthened wheelbase.
