Alpine A110

Launched in 1961 the A110, like previous road-going Alpines, used many Renault parts, including engines. While its predecessor the A108 was designed around Dauphine components, the A110 was updated to use R8 parts. Unlike the A108, which was available first as a cabriolet and only later as a coupé, the A110 was available first as a Berlinette and then as a cabriolet. The most obvious external difference with the A108 coupé was restyled rear bodywork. Done to accommodate the A110's larger engine, this change gave the car a more aggressive look. Like the A108, the A110 featured a steel backbone chassis and a fiberglass body. The A110 was originally offered with 1.1 L R8 Major or R8 Gordini engines. The Gordini engine has a power output of 95 hp (71 kW) SAE at 6,500 rpm.

A110 GT4

The A110 achieved most of its fame in the early 1970s as a successful rally car. After winning several rallies in France in the late 1960s with the cast-iron R8 Gordini Cléon-Fonte engines the car was fitted with the aluminium-block Cléon-Alu from the Renault 16 TS. With two twin-venturi Weber 45 carburetors, the TS engine has a power output of 125 hp (93 kW) DIN at 6,000 rpm. This allowed the production 1600S to attain a top speed of 210 km/h (130 mph). The long-wheelbase Alpine A108 2+2 Coupé was replaced with the new, restyled 2+2 Coupé based on the A110 mechanicals called the A110 GT4.

The car achieved international fame during the 1970–1972 seasons competing in the newly created International Championship for Manufacturers, winning several events around Europe, earning a reputation as one of the strongest rally cars of its time. Notable performances included a victory in the 1971 Monte Carlo Rally with Swedish driver Ove Andersson.

With the buy-out of Alpine by Renault complete, the International Championship was replaced by the World Rally Championship for 1973, at which time Renault elected to compete with the A110. With a team featuring Bernard Darniche, Jean-Pierre Nicolas and Jean-Luc Thérier as permanent drivers and "guest stars" like Jean-Claude Andruet (who won the 1973 Monte Carlo Rally) the A110 won most of the races where the works team was entered, making Alpine the first World Rally Champion. Later competition-spec A110s received engines of up to 1.8 litres.

A110 1600SX

As well as being built at Alpine's own Dieppe factory, versions of the A110 were built under license by various other vehicle manufacturers around the world. From 1965 to 1974 the car was produced in Mexico under the name "Dinalpin" by Diesel Nacional (DINA), who also produced Renault vehicles. From 1967 to 1969, the A110 was also produced in Bulgaria under the name "Bulgaralpine" by a partnership formed between SPC Metalhim and ETO Bulet, whose collaboration also resulted in the production of the Bulgarrenault.

In Spain, Alpine A110 were produced by FASA in Valladolid between 1967 and 1978.[4] These were the only versions built outside France that were commercialised under the same names and to the same specifications as the French-built ones. FASA manufactured version A110 1100 (from 1967 to 1970) with 1108 cc engines, version A110 1300 (from 1971 to 1976) with 1289 cc engines, and version A110 1400 (from 1977 to 1978) with 1397 cc engines.

In 1974, the mid-engine Lancia Stratos which was the first car designed specifically for rally racing, was operational and homologated. At the same time it was obvious that the rear-engine A110 was nearing the limits of its development potential. The adoption of fuel injection brought no performance increase. On some cars, a DOHC 16-valve head was fitted to the engine, but it proved unreliable. Chassis modifications, such as the usage of the A310's double wishbone rear suspension, homologated with the A110 1600SC, also failed to increase performance. On the international stage the Stratos proved to be the "ultimate weapon", making the A110, as well as many other rally cars, soon obsolete. The A110 is still seen in events such as Rallye Monte-Carlo Historique.

In 2012, to mark the 50th anniversary of the A110, Renault produced a concept car called the A110-50. The modern version of the A110 was introduced by Renault in 2017.

The A110 was fitted with a variety of engines over its production life-span. Engines used on production cars included the following:

Unique characteristics:
Due to the rear-mounted engine there was no air-intake grille on the front of the body. Air was scooped from below the chassis and exhausted through near-horizontal openings on the rear fenders above and aft of the rear wheels for cooling.[8]
