The story
History
The design was German. Egon Brütsch of Stuttgart built small cars whose bodies were two egg-shaped fibreglass shells, joined round the middle by a strip of rubber, and he sold the right to make them across Europe.source 1 His Brütsch 200 prototype was shown at the Paris Salon of 1954.source 2 The story of Brütsch is mostly a story of licences, and the Avolette is one of the cars built under licence from him.source 3source 2source 4
He was more successful at licensing his concept to various European firms than he was at building them himself.
The French licence went to the Société Air Tourist, headed by Jean Avot, which was the French agent for Cessna aircraft.source 1source 2source 5 The cars were assembled in a hangar on the former military airfield of Toussus-le-Noble, about 16 km (10 miles) west of Paris.source 6source 2 Air Tourist sold aeroplanes rather than building them, which makes the Avolette a cousin of the aircraft makers’ microcars rather than one of them. The English Wikipedia says Air Tourist also built Brütsch’s Zwerg under licence, in single- and two-seat forms.source 7
From Brütsch-Avolette to L’Avolette
At the Paris Salon of October 1955 the car was shown as the Brütsch-Avolette, and it was in essence a Brütsch 200, still wearing the German chrome script on its nose. It had twin faired-in headlamps, an Avolette decal under the bumper, portholes in the tail, a fixed steering column, Brütsch’s single T-tube frame, and a 175 cc Ydral engine in place of the Sachs.source 2 Avot was not happy with that frame and, the Weiner museum says, designed his own tubular backbone.source 1 The production car’s frame, as RM describes it, kept the T-tube but stiffened it with two D-shaped hoops ahead of and behind the cockpit, joined under the cockpit rail to make a cage.source 2
By the October 1956 Salon it had become L’Avolette, and it had changed a great deal, though it was still a three-wheeler with its single wheel at the back.source 2source 4 A single “Cyclops” headlamp ran the length of the bonnet. Polished cast-aluminium wing guards doubled as step plates, a proper chrome-framed windscreen stood up front, and vertical air slits appeared in the rear flanks. It was steered by Bowden cable, and sprung by Neidhart rubber-in-torsion units at the front and Niemann rubber rings at the rear.source 2 The coupé on the stand had a near-spherical top that slid back. Production coupés had something simpler: a tube-framed top with Plexiglas sides and a fabric roof, which tipped forward over the windscreen to let the occupants climb in, since no Avolette had doors.source 2source 1source 6
Five versions, one hangar
There were five versions, and the code on each said what it was: the number gave the engine size, the letter Y, S or M named Ydral, Sachs or Maico, and C or D marked a coupé or a décapotable, a convertible.source 1 The basic Normale, with a 125 cc Ydral, was started by hand and could be driven without a licence, one of the post-war 125 cc licence-free cars.source 3source 2 The Tourisme had a 175 cc Ydral, a top and a heater. The Tourisme de Luxe had the 191 cc Sachs of the Messerschmitt KR200.source 2source 6
The fastest, the Record de Luxe, was the odd one out: it ran on four wheels, two of them close together at the back, and used the 250 cc Maico engine of the Maicoletta scooter, with a rocking starter that RM likened to a washing machine’s. It was claimed to reach 110 km/h (68 mph).source 1source 2 Both of the Weiner museum’s cars had four gears forward and four in reverse.source 1source 6 A Compétition de Luxe with a differently styled body was dropped from the brochures early on.source 3source 6source 2
The Weiner museum dates production from the autumn of 1956 to the summer of 1957; the German and English Wikipedias end it in 1958.source 1source 6source 4source 8 How busy the hangar was is suggested by a journalist, never named, who came to the airfield to road-test a car and, RM reports, found the large hangar full of vehicles in various states of assembly.source 2 In 1957 a softer-shaped “New Avolette” with a Lambretta engine of 125 or 150 cc was shown at the Cycle Salon; RM thinks it may have been the Compétition rebodied, and says it came to nothing.source 3source 2 Brütsch’s last design then found another French maker, the V2N below.source 3source 6
