Exhibited at the Paris Motor Show in October last year the 1973 A-110 models have lost the little side indicators which were located between the front wheel arch and the door. The smallest model is now called the "1300". In March the 1600 S received a larger 1605 cm³ engine and rear suspension adopted from the A-310. This new version is called "1600 SC". The "1600 S grupe IV" is only available to special order and it is intended for amateurs who want to participate in World Rally Championships.
The A-310 gained a wing mirror on the driver's door. In March at the Geneva Motor Show a new version 1600 SI was introduced with a fuel injection system instead of a carburettor fitted to the engine, but this is intended for export only.
The 1974 models were introduced in October at the show in Paris. The A-110 has new wheels from the A-310 and no door handles which have been replaced with push-buttons. The Bosch fuel injection on the A-310 becomes standard and the ventilation slots on the bonnet have been moved forward.

Despite great sports results, Alpine's financial situation continues to deteriorate.This is caused by the costly development of the new A-310, which is having a difficult start and falling sales of the ageing berlinettes. At the beginning of June 1973, this worrying situation led Jean Rédélé, the boss of Alpine, to sign an agreement with Renault. They would inject capital and become the principal shareholder of the Dieppe brand. From now on, the cars will be called Renault-Alpine.
