Model year changes
Since its launch in 1991, the 6.75 L Garrett-turbocharged V8 engine from the Turbo R was chosen for use in the Continental R. In early cars (produced from 1991 to 1993) power output of 325 hp at 4,000 rpm and peak torque of 450 lbft at 2,000 rpm was available, although this was always estimated as at that time, Rolls-Royce still had a policy of not supplying official figures, preferring to describe power output simply as "sufficient".
The car used the new 4-speed GM 4L80-E automatic transmission which had been exhaustively tested by Rolls-Royce, over 1000000 mile, and modified by them to deliver very high levels of refinement.[11] The car featured self-levelling hydraulic suspension (with adaptive ride/Automatic Ride Control) and ventilated disc brakes at the front with twin calipers. Engine management was done via the MK-Motronic digital fuel injection with fully mapped ignition control system. At launch, advertised top speed was 145 mph, along with a acceleration time of 6.6 seconds. The Continental R was priced at US$271,780 in 1992 and £178,000 in the UK at its launch.
All cars were equipped with a centre console mounted electronic gear selector (the first time Rolls-Royce had made a car without the autobox selector on the steering column), with a Sport button to simultaneously adjust gearbox mapping and stiffen the suspension for more aggressive driving and handling. For such a large and heavy car, the Continental R was repeatedly acknowledged by road testers and journalists as displaying superb handling characteristics at high speeds.[12][13]
Prices of the Continental R in the UK rose to £180,120 in the 1994 model year. That year also saw a number of revisions to the engine, including revisions to the cylinder heads courtesy of Cosworth (another company within the Vickers group, alongside Rolls-Royce and Bentley). The alloy wheels were also increased in diameter to 17-inch and were of a completely new 7 spoke design. Power output of the engine was now estimated at 360 hp at 4,000 rpm and peak torque 500 lbft at 2,000 rpm. By the 1996 model year, the Continental R was priced at £187,354 in the UK. The year saw some of the most significant changes since the launch of the car, notably the inclusion of the liquid cooled chargecooler as standard, along with an improved Zytek EMS3 engine management system which meant improvement in throttle response and fuel efficiency along with a digitally controlled turbo over-boost. Power output of the engine was increased as a result, and a change in policy by Rolls-Royce: this was the first time performance figures were officially released by the manufacturer, departing from a long tradition of describing performance as "adequate" or "sufficient". Probably the reason for this is because the figures were very impressive: 385 hp at 4,000 rpm and torque of 550 lbft starting to be available at only 2,000 rpm, and available up to 4,000 rpm (according to UK brochure). No other production car in the world at the time delivered such levels of torque. This lead British publication Autocar to suggest, when road testing the 1996 Continental R in August 1995, that the gearbox would've been destroyed due to the enormous levels of low down torque available.[12] was now officially quoted by Rolls-Royce as "sub 6 seconds" along with a top speed of 155 mph, according to the UK brochure. The 1996 model year also saw revised 17-inch alloy wheels and steering wheel tilt adjustment for the first time. This was electrically adjustable and so could now be set as part of the seat and wing mirror memory positions. Electronic Traction Assistance System began to appear on the later 1996 model year cars. In the 1998 model year, the electronic traction assistance system was included as standard and some cosmetic changes were made. Power and torque of the engine remained the same as before, but 0–97 km/h acceleration time was now quoted as "6 seconds".
Between 1999 and the end of production in 2003, Bentley indulged customers in a variety of special customised cars under their Personal Commission programme with a number of cars fitted with the 420 hp engine including the Le Mans, Continental R, Continental R 420 and Millennium. A total of 194 Continental R cars had the 420 engine – some of which were also wide body cars.
