         The Rover SD1 models, see the difference....         

Dimensions and sizes compared to competition.

Length: 4.7m

With its length of 4.7m, the Rover is 8 cm longer than the Ford Granada and the Audi  100. More than half of the total length of the Rover is taken over by the wheelbase,  which results in a ratio wheelbase/length of 0.60.  A value which is equal to that of the  Granada and significantly better than that of the Audi. The inevitable advantage is more  comfort. The rear seats can now at or above the rear wheels are placed thus less shock  penetrate the interior while available seat width is not reduced by inwardly extending  fenders.

Legspace

In order to optimize comfort the passenger seats new cushions and backrests were given  to the new seats in 1981. The seat was supplied with a mechanical transport mechanism.  Knee space was improved for passengers in the backseat. And the backseat was lowered  so that there was more headroom in the back of the car. The legroom in the Rover is  evenly distributed between the front and rear so that there is sufficient space even when the seat is placed completely backwards. Compared to other cars like the Renaul 30, the  space available is beneficial.  

Rovers Aerodynamic design

The uncomplicated aerodynamic lines of the Rover with the front spoiler produce a body  shape with a lower air resistance. The drag coefficient is 0.40 and it is slightly above the  value in its class, and significantly lower than for example the BMW 520.  The shape of the front spoiler is an important factor which approves the stability of the  car in a straight line. The front spoiler acts as an air dam thereby preventing the  turbulence in front of the vehicle. This reduces the resistance. The lower portion of the  spoiler streamlines the air flow under the vehicle, making the front comes up less.  Another factor that contributes to the stability of the Rover is the crosswind pressure  point which lies in line with the center of gravity. Disturbance caused by side winds are  kept to a minimum. 

Improved stability

The form of the spoiler is an important factor which contributes to the stability-in-  straight-line there, at the front of the vehicle, there is a better airflow processing so  that both resistance as front elevator be reduced. A section of the tailgate spoiler Rover acts as an air dam that prevents the vehicle for  the turbulence occurs. This will reduce the resistance. The lower section of the tailgate  spoiler 'flow' aligns the air flow under the carriage causing the front less comes up.  Another factor which contributes to the stability of the Rover is the wind pressure point  that is in line with the center of gravity. Disturbance caused by side wind is limited to a  minimum since the wind pressure are performing power on the most stable part of the carriage. 

Less air noise

The total aerodynamic design of the Rover is enhanced by the careful design of details  such as the outside mirrors and the high production standards which both door and  window seals must comply. This ensures that the wind noise to a minimum which  contributes to the silent, comfortable interiors of the Rover.
