Talk:Alpine A110 1600S '73/@comment-212.139.217.244-20171221115906

The information about the 1600 S is incorrect. The Alpine A110 "1600 S" was first shown at the Paris Salon of 1969 and was the homologation production base car for Alpine's then current competition cars. It was powered by a highly tuned 138 hp 1565cc engine breathing through two twin-choke Weber 45DCOE carburettors. It was fitted as standard with a 5-speed all synchromesh gearbox with a reinforced differential assembly. The car had double wishbone front suspension, swing axle rear suspension and was fitted with disc brakes all round and weighed 685 kg.

A 1596cc "Groupe 4 Usine" version incorporated all the necessary modifications for rallying with engine development by Marc Mignotet, larger wheels and brakes, wide wheel arches, perspex side windows and rear screen, Hewland LSD and a 98 litre flexible fuel tank mounted inside the cockpit.

The second series of the 1600 S appeared in spring 1973 and was mechanically the same as the first series apart from being fitted with a 138 hp 1605cc engine. The larger engine enabled Alpine to use a larger engine for the "1600 S Group 4 Usine" and a 1796cc engine was again developed by Marc Mignotet who raised the power output to about 180hp at 7000 rpm.

These changes enabled Alpine to field cars with sufficient power to win the inaugural World Rally Championship for Makes in 1973 with the 1796cc A110 1600 S.

Approximately 1600 examples in total of the 1565cc and 1605cc 1600 S were produced.

In 1974 the rear suspension of the 1600 S was changed from swing axles to double wishbone. The engine capacity remained at 1605cc and the car designation was changed to 1600 SC for cars with 140 hp engines fitted with Weber 45 DCOE carburettors and to 1600 SI for the cars with 145 hp engines fitted with Bosch electronic fuel injection intended for certain export markets. The cars had 5-speed all synchromesh gearboxes, disc brakes all round and the weight increased to 710kg.

A "Groupe 3 Usine" version was offered in 1975 based on the "SC" and "SI" with a 5-speed gearbox that had been suitably strengthened for rallying and on the "1600 SI" version the Bosch fuel injection was replaced by a Lucas competition system.

The total number of 1600 SC/SI produced is reported as from 481 to 588. Tim Moores ex-A110 Registrar, Club Alpine Renault UK
