The caur wis available frae launch as a three-door hatchback wi 1.0, 1.1 an 1.4-litre TU-series belt driven OHC ingines. Shortly afterwards, a five-door model an a 1.4 diesel wur introduced; the latter wis later replaced bi a 1.5-litre unit. It haed fully independent lang travel suspension. It wis initially backed bi a memorable TV advertisin campaign filmed in Cheenae, starrin actress Janet Mas an an elderly gentleman, whose character wis simply kent as Mr Wong.
The caur wis vera economical, lairgely acause o excellent aerodynamics for its class o caur (drag coefficient of 0.31) an a vera licht weight o 640 kg (1,411 lb) for the basic version. This wis due tae the extensive uise o plastic panels in non-load bearin auries an varyin the thicknesses o steel in the bodyshell tae be the minimum needit tae take required loads. It an aa optionally uised self coloured plastic bumpers. This technology came frae the PSA Peugeot-Citroën / Renault / French government ECO 2000 project. The production version wis muckle mair conservative than the oreeginal 'ane box' design prototype, that wis closer tae the Eco 2000 stylin efter negative reactions in focus groups. The 'ane box' supermini eventually came tae market wi the early '90s Renault Twingo. In 1989 a naturally aspirated diesel AX, uisin the 1360 cc aw aluminium alloy TUD ingine, managed a figure o 2.7 litres per 100 kilometres (100 mpg-imp; 87 mpg-US), totallin ower 1,000 miles (1,609 km) frae Dover tae Barcelona. This wis the langest iver distance travelled on 10 imp gal (45.5 L; 12.0 US gal) o fuel an earned it a place in the Guinnes Warld RecordsGuinness Beuk o Records as the maist economical production caur. An aa available wis a 4x4 variant, but wi limited success when compared tae the rival Fiat Panda 4x4. This wis no sauld in the UK.
The first performance version wis the limitit-run AX Sport frae 1987, wi a 1.3 ingine an twin carburettors producin 95 bhp (71 kW; 96 PS), wearin iconic white steel wheels (5,5" x 14") which resembled those on its brither, the Peugeot 205 Rallye. The AX Sport uised Solex ADDHE 40 carburettors till 1990 an wis then replaced wi Weber DCOM 40s, juist like the 205 Rallye 1,3. The AX Sport haed a shorter inlet manifauld than the 205 Rallye, tae save room in the smawer ingine compartment. Later on the sport wis lichtlie revised, available in ither colours an wi optional GT wheels. Later, the AX 14GT, wi a single-carburettor 85 bhp (63 kW; 86 PS) 1.4 ingine an aa foond in the Peugeot 205 XS, wis introduced. Frae 1991, this model utilised fuel injection tae coincide wi the revamp o the entire range an tae coincide wi tougher 1992 EU emission regulations that introduced exhaust catalytic converters.
Late 1991 saw the range revised, wi a hivily face liftit tailgate an interior being the maist notable chynges. The follaein year saw the introduction o the maist pouerful AX variant, the 100 bhp (75 kW; 101 PS) GTi. The GT wis sauld alangside the GTi for a few months, but wis eventually phased oot. New models wur introduced such as the Forte, Spree, Elation an Dimension
The range wis slimmed-doun in 1996, follaein the introduction o the Saxo, wi production o the AX endin in 1998 efter a 12 year production run.
In Januar 1995 the Citroen AX Echo wis creatit, reachin a top speed o 110 mph (180 km/h). Its competitor at the time, the Peugeot 106 Ski, wis lackin interest on buyers in Europe whilst the Citroen AX's sales wur sky hie.
The Peugeot 106 an Citroën Saxo wur baith developments o the AX. They follaed the '90s trend for hivier, mair solid an 'safer' feelin caurs that continues today. The AX wis designed for lichtness, wi a 'less is mair' philosophy, but wi mair conventional stylin than previous Citroëns.
AX derivatives 
The Citroën AX BB Cabrio wis a smaw roadster derived frae the AX (1988). In Portugal, Citroen dealership Benjamin Barral creatit an unoffeecial convertible version, cawed the BB Cabrio, oreeginally pouered bi the twin-choke carb AX GT 1.4 L ingine, but later available wi ony type o ingine that equipped the 3 door AX. Considered vera handsome, due tae the lack o the uisual roll bar that convertible normally require, these caurs are nou collector's items an command a hivy premium ower the normal models they are based upon. This model wis no sauld in the UK.
At ane stage, parent firm PSA Peugeot Citroën haed planned tae launch a Talbot Samba replacement as a version o the AX wi a different grille an a Talbot badge, but this plan wis cancelled, as the entire Talbot marque wis axed in the same year the AX wis launched.
Aixam Mega at ane time built an AX derivative cawed Mega Club. It wis somewha inspired bi the Méhari, wi a plastic bodywirk an an optional convertible version, wi 2 wheel drive or fower wheel drive. It wis discontinued in 1998. A competition version o the Mega Club wi a tubeframe chassis raced in the Andros Trophy in the early 1990, but pouered bi Ford an Honda ingines.
