driver to know the side lights were functioning. Overdrive was made an option. These amendments were announced on 11 September 1956. Rover 60 The Rover 60 was announced on 24 September 1953 to add a more economical four-cylinder engine to Rover's range though leaving trim and equipment the same as the 75 and the new Rover 90 announced at the same time. Rover's idiosyncratic central gear change lever designed to allow three-abreast seating in front was used for this new car. Its 2.0 L (1997 cc/121 in³) engine had been used in the early Land Rover though it now had modifications including an SU carburettor. As the block was shorter than that of the 6-cylinder engine, it sat further back in the frame, and this is sometimes held to have resulted in better handling and compensated for the lack of power. The Rover 60 shared with the Rover 75 and Rover 90 the October 1954 modifications: a bigger boot, wide rear window and flashing directions indicators all announced at the Paris Motor Show. Independently adjustable separate front seats were made available at extra cost from September 1955. In the same way Rover 60 buyers were given the choice of a different style of front seat, two individual seats independently adjustable, available at extra cost from September 1955. Similarly in September 1956 the shape of the front mudguards was rearranged with the side lamps and flashing indicators in different positions. A small chrome reflector on the headlamp rim allowed the driver to know the side lights were functioning. Overdrive was made an option. In their test of the Sixty in 1954 The Motor magazine recorded a top speed of and acceleration from 0– of 26.5 seconds. A fuel consumption of was recorded. The test car cost £1162 including taxes. The Rover 60 was replaced by the Rover 80 which used an updated version of the overhead-valve 2286 cc (138 in³) four used in the Land Rover of that time. The Rover 80 was announced on 24 October 1959. Rover 90 The top-end Rover 90 appeared with a much larger more powerful inline-six at the same time, 24 September 1953 as the four-cylinder Rover 60 was introduced. Rover's idiosyncratic central gear change lever designed to allow three-abreast seating in front was used for this new car. This engine produced 90 hp (67 kW) and could propel the car to reach 90 mph
