Alpine A110
The Alpine A110 is a  sports car produced by French automobile manufacturer Alpine from 1963 to 1977. The car was styled as a "berlinette", which in the post-WWII era refers to a small enclosed two-door berline, better-known as a coupé. The Alpine A110 succeeded the earlier A108. The car was powered by a succession of Renault engines. A car also named Alpine A110 was introduced in 2017.

The Alpine A110 experienced a remarkable evolution in terms of power output throughout its production years. Initially, the A110 had an output of just 51 horsepower, which was adequate for a car weighing only 620 kilograms. However, by the end of the A110's production run, its power output had increased to 180 horsepower. This impressive increase in power contributed to the car's success on the rally stages of Europe. The A110's crowning achievements included 1-2-3 finishes at both the 1971 and 1973 Monte Carlo rallies, and it used Renault 16 engines at the time. In 1973, Alpine won the inaugural manufacturer's World Rally Championship, defeating competitors such as Lancia, Porsche, and Ford. However, by 1974, advances in rally competition led to a significant shift in the landscape of the sport, and the Alpine A110, which had become outdated, struggled to keep up with its rivals. As a result, sales of the A110 declined, prompting Renault to step in and purchase the company outright in an effort to save it. Despite being surpassed by newer rally cars, the A110's legacy as a successful and iconic rally car remains, and its victories in the early 1970s solidified its place in motorsport history.

History
Alpine was founded by Jean Rédélé, a Frenchman based in Dieppe, who was an enthusiastic participant in rallying during the post-WWII era. Redele used Renault 4CVs and modified them for improved performance, including replacing the original three-speed gearbox with a five-speed manual transmission—a significant upgrade at the time. He also constructed new, lighter bodies to fit over the chassis and entered his modified vehicles in endurance races, including Le Mans and Sebring. Redele's success in rallying and continued improvement of Renault vehicles eventually gained the attention of Renault, leading to factory financial support. He formally established the Societe Anonyme des Automobiles Alpine and named the company "Alpine" as a tribute to his previous successes rallying in the Alps.

Launched in 1963, 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 departure from the A108 coupé was a restyling of the 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. 
Alpine was a pioneer in the use of glass-fibre body panel construction, which was valued for its lightweight properties and malleability. This innovation allowed the company to produce its first proprietary body, the A106, which was placed on top of the old Renault 4CV chassis. The reduced weight of the body contributed to the car's success in rallying. Later, a cabriolet version was introduced, based on a stiff, tubular backbone chassis design that would become the foundation for all Alpines until the final production of the A610 in 1995.

The A110 was originally offered with 1.1 L R8 Major or R8 Gordini engines. The Gordini engine has a power output of  SAE at 6,500 rpm.

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  DIN at 6,000 rpm. This allowed the production 1600S to attain a top speed of . The long-wheelbase Alpine A108 2+2 coupé was replaced with a 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 events throughout Europe, and 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.
Alpine played a key role in Renault's entry into Formula One. During the 1970s, Alpine had been involved in Formula Three and Formula Two track-racing series and ultimately persuaded Renault to enter Formula One. Alpine had built a Formula One testing mule by 1976, leading to Renault's full-scale entry into the prestigious global motorsport category. This involvement marked one of Alpine's enduring legacies, as Renault continues to be active in Formula One to this day.

After Alpine's acquisition by Renault in 1971, 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.

In addition to 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), which 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, the Alpine A110 was produced by FASA in Valladolid from 1967 to 1978. 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", soon making the A110, as well as many other rally cars, obsolete. The A110 remains a staple of vintage racing events such as the Rallye Monte-Carlo Historique.

The Dieppe factory that served as the base for Jean Redele and Alpine continues to operate and produce cars. Notably, the legendary Renault 5 Turbo was built at the Dieppe factory. In more recent years, the factory became the headquarters of Renault Sport, where renowned performance cars such as the Clio 172, 182, Trophy, and the Megane R26.R and 275 Trophy R were designed and developed. This legacy of performance car development can be traced back to Dieppe and ultimately to the influence of Alpine and Jean Redele.

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

Engines
The A110 was fitted with a variety of engines between 1963 and 1977. The Alpine A110, driven by Jean-Luc Therier, became the first vehicle ever to win an international rally with a turbocharger when it secured victory at the 1972 Criterium des Cevennes rally. This achievement predated the introduction of Audi's turbocharged Ur-Quattro by eight years Engines used on production cars included the following:
