The story
History
Guillem Tachó of Manresa, in the province of Barcelona, built one-off cars of his own first: “La Ballena”, the whale, in 1950, and “El Coca” in 1953. The second gave him the idea of a microcar in series.source 1source 2 On 4 May 1956 he and his brother Antoni founded Automóviles Utilitarios, S.A., AUSA for short, with Maurici Perramon and Josep Vila, and the car took its name from three of the surnames: Perramon, Tachó, Vila.source 1source 2 The Spanish sources write the founders’ names in Castilian, as Guillermo, Antonio and Mauricio Perramón; the Catalan ones use the forms here.
The car took about two years to develop. The prototype of 1956 had AUSA’s own 250 cc engine, with an alloy piston and cylinder head.source 3 In production it was a 247 cc two-stroke single of 11 CV, mounted across the tail and driving the rear wheels, under an open steel body on a tubular frame, with or without doors.source 1source 2 At 2,950 mm (9 ft 8 in) it was only just shorter than a Fiat Nuova 500, the car this site measures every microcar against.source 1source 2 It was shown on a stand at the Barcelona trade fair, the Feria de Muestras, and it cost 44,500 to 55,000 pesetas.source 1source 2
A step above the Biscúter
Doors, two-tone paint, chrome and 12-inch wheels aimed the PTV at buyers who wanted more than a Biscúter. The Weiner museum notes that with independent front suspension, big wheels and an enclosed body, the PTV even allowed some talk of comfort, which a Biscúter did not.source 3 It is remembered as the best-looking of Spain’s home-grown microcars, especially in two-tone paint.source 1source 2 It sold across Spain, and Spanish Wikipedia counts the exports: 18 cars to Portugal, one to the United States and one to an Arab sheikh.source 1 Bumpers and other extras were added over the years.source 3
AUSA also built 45 commercial vehicles on the 250 between 1959 and 1961, though with the engine at the back there was little room for a load. A van prototype with its engine at the front stayed a one-off, and AUSA used it as a works vehicle for years.source 1source 2 In 1960 came the PTV 400, longer, with a supercharged two-stroke twin of 396.83 cc and 19 CV for 110 km/h (68 mph). It stayed a prototype: it was ready just as the SEAT 600 arrived.source 1source 2 A 350 cc engine was also planned, but it never went into production.source 3
The micro-killer
The SEAT 600, known in Spain as the micro-killer, overwhelmed it.source 1source 2source 3 Production stopped in 1961. By the Weiner museum’s reckoning the PTV had been Spain’s second-biggest-selling microcar, after the Biscúter; the Spanish sources put it fourth, behind the Biscúter, the Spanish Goggomobil and the Spanish Isetta.source 3source 1source 2 Both can be true, if it was second among cars designed in Spain and fourth once licence-built foreign designs are counted; that reading is ours. Its smaller countrymen are on the page of Spanish microcars.
AUSA did not close. Around 1961 it built a tipping tricycle, which led to its famous Dumper, and it became a world leader in site dumpers and forklifts under three tonnes.source 1source 2source 3
