The Alfa Romeo Dauphine preserved the classic three-box, four-door body configuration, with an overhanging
rear-mounted engine and rear-wheel drive. The engine employed was the well-known inline four-cylinder
water-cooled block called "Ventoux", with an 845 cc displacement, which had its origins tied to the old
Renault 4CV. At the rear, the vehicle utilized a swing-axle pendular suspension, a mechanical solution
praised for its comfort in absorbing ground irregularities and for optimizing the interior space of the
passenger compartment thanks to the absence of a central transmission tunnel.
The model's technical and market evolution occurred through gradual mechanical modifications and the
introduction of new trim levels. At its launch in 1959, the 845 cc engine came equipped with a single-barrel
Solex 28 IBT carburetor, generating a maximum output of 26.5 horsepower. This setup worked connected to a
three-speed manual transmission, with an unsynchronized first gear. The three-speed gearbox and the lack of
power on climbs were met with reservations by Italian buyers, accustomed to the country's mountainous
terrain.
Alfa Romeo acted quickly and, in May 1960, began installing the four-speed manual transmission (originally
used in the French Gordini version). This more elastic gearbox became standard factory equipment at the end
of that same year, significantly improving the utilization of engine power. In October 1960, to expand its
market presence, the manufacturer launched the Ondine Alfa Romeo (Type R1090A), a luxury version of the
sedan. The Ondine was distinguished by its superior finish, featuring a greater number of chrome trims on
the sides, perforated steel wheels, rubber overriders on the rear bumpers, a fully carpet-lined front trunk,
and a cabin with improved acoustic insulation and premium fabrics. To make the sale of the Ondine viable at
845,000 lire, Alfa Romeo reduced the sticker price of the entry-level Dauphine to 795,000 lire in December
1960.
New evolutions emerged at the end of 1961, when the four-speed transmission received full synchronization for
first gear. Simultaneously, the powerplant adopted the Solex 28 IDT carburetor, which raised the maximum
working power to 32 horsepower. Historical records also point out that Alfa Romeo made available a
high-performance version in a limited series of 2,200 units between 1961 and 1962, dubbed the Dauphine
Rallye 1093 (Type R1093). This version featured a tuned 845 cc engine fed by a twin-choke Solex PAIA-3
carburetor and a higher compression ratio, generating 49 horsepower. The sporty model came with a complete
instrument panel, sporty decorations, and, sporadically, was offered in a low-run convertible body style.
In September 1962, the luxurious Ondine version was discontinued at Portello after an estimated production of
about 2,000 examples. From that point on, manufacturing operations focused solely on the base berlina. For
the 1964 model year, Alfa Romeo carried out the only and discreet facelift in the model's trajectory,
updating details of the instrument panel and applying new exterior chrome trims. Mechanically, the engine
received the Solex 28 IFT carburetor, maintaining the 32 horsepower, but optimizing fuel consumption. The
great technical innovation of this final facelift was the installation of disc brakes on all four wheels as
standard, a significant engineering advancement compared to the drum brakes common in the category,
guaranteeing the Dauphine much safer and more stable braking.
