Even more sophisticated aerodynamic design. Even cleaner, swifter lines for front end, hood and fenders. New quad headlights. A newly engineered instrument panel. A tachometer. That's the new Citroen D series for 1971. There's new stability and performance and silent comfort in the 100 to 115 mph range. And great new cruise economy, as well—up to 29 mpg!
Four-cylinder, five-bearing hemi units from 1985 to 2175 cc. Your choice of four-speed, all-syncro transmission or Citromatic Drive depending on model. Then there's Hydropneumatic suspension with its constant-level ride. Adjustable road clearance. Power assisted rack-and-pinion steering. And of course, Front Wheel Drive. Interiors are more elegant than ever, too. Fully carpeted. Fully lined with fabric and padded vinyl. Leather throughout, if you like.
