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: at 4,000 rpm and torque of 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. 0–97 km/h was now officially quoted by Rolls-Royce as "sub 6 seconds" along with a top speed of (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". The cosmetic revisions included fitting the same front seats as fitted to the convertible Azure, which were shared with the BMW 8 Series and trimmed by Rolls-Royce, featuring an integrated seat belt. Other revisions included small mesh vents below the headlights, laser-cut mesh radiator grille as standard, revised alloy wheels and minor changes to front and rear bumpers. 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 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. Models Continental S The Continental S was a limited-edition performance model introduced in 1994 and 1995 with a liquid cooled chargecooler added. Only thirty seven were produced
