1976/1983 Ferrari 308GTB Group B Michelotto
Chassis no. 18869
Engine no. 00385
Introduced at the Paris Salon in 1975, the stunningly beautiful 308GTB – Ferrari's second V8-engined road car - marked a welcome return to Pininfarina styling following the Bertone-designed Dino 308GT4. Badged as a 'proper' Ferrari rather than a Dino, the newcomer had changed little mechanically apart from a reduction in wheelbase, retaining its predecessor's underpinnings and transversely mounted 3-litre V8 engine that now featured dry-sump lubrication. In road tune this superbly engineered power unit produced 255bhp, an output good enough to propel the 308 to a top speed of 150mph. Produced initially with glassfibre bodywork - the first time this material had been used for a production Ferrari - the Scaglietti-built 308GTB used steel exclusively after April 1977. The first steel bodied cars were manufactured in 1976, the change bringing with it a considerable weight penalty (of around 150kg) and consequent reduction in performance. Naturally, anyone wanting to race a 308GTB started out with the glassfibre version if they could.

For 1983, the FIA governing body of international motor sport introduced its new Group B regulations for major-league rallying, prompting the specialist Italian conversion and preparation company Michelotto develop a Group B variant of Ferrari's very popular and highly successful 308GTB. Since production of the required 25 highly modified GTB Evoluzione cars was effectively out of the question, the specification of these Michelotto Group B machines was changed little from that of the standard road car, while still providing clients with rally-winning potential. Michelotto's most significant departure from its previous Group 4-converted cars was selection of the Quattrovalvole (four-valves-per-cylinder) engine. Even so, Michelotto's first 308GTB emerged with the conventional and proven 'two-valve' engine rather then the latest 'QV' power unit employed in the following three cars.

Offered here, Ferrari 308GTB chassis number '18869' was the first of four Group B cars built by Michelotto from a total of 15 combined Group B and Group 4 cars that the company modified in period. It was completed in February 1983 for the Pro Motor Sport team in Italy.

It is understood that during the subsequent 1983 rally season, this car won many Italian national events, including the Valli Imperiesi Rally with Cambiaghi/Di Gennaro as driver and navigator; followed by the Sciacca Terme, Mari e Monti, 12 Hours of Campobello, Neborid and Proserpina events crewed by Bronson/Di Prima. The car's successful career continued into 1984 as Zanini and Autet campaigned it in the Spanish Championship and won another six times: in the Criterium Guilleres, Sierra Morena, San Agustin, Luis de Baveria, Oviedo and Vasco Navarro Rallies.

These remarkably successful though relatively little known competition Ferraris featured Rose-jointed suspension and up-rated Brembo brakes all round, new Canonica wheels and Pirelli tyres as standard although parts were routinely changed and updated during their competitive careers. The forced substitution of Campagnolo wheels for the narrower, more standard looking five-spoke Canonicas reduced track 
width compared to the sister Group 4 circuit-racing cars.

Three of Michelotto's Group B 308s were fitted with QV 32-valve engines producing 310bhp at 8,000rpm after this prototype (chassis '18869') had had been completed with the 288bhp two-valve motor. While the Group 4 variants used Kugelfischer mechanical fuel injection, the Group B rally cars employed the Bosch K-Jetronic electronic system. These Group B variants weighed around 30kg heavier than their racing counterparts since they had to retain their stock glassfibre and steel body panelling.

Since acquisition by the current vendor the gearbox has been overhauled and the rear boot area rebuilt. The car now comes with a French Carte Grise and Ferrari Classiche Certification has been applied for.

As the first - and one of the most successful - of this rare quartet of Michelotto-built Ferrari 308GTBs, this is a particular interesting and significant example of the Ferrari Berlinetta Competizione breed. As a past participant in the 'Tour Auto', the car represents a fast and stunning entry ticket into suchlike prestigious events and is worthy of the closest inspection and consideration.

La Ferrari 308GTB châssis numéro 18869 proposée ici était la première de quatre Groupe B construites par Michelotto sur un total de 15 voitures, comprenant des Groupe B et des Groupe 4, que la société a modifiées à l'époque. Elle a été achevée en février 1983 pour l'écurie Motor Sport en Italie.

On sait qu'au cours de la saison de rallye suivante en 1983, cette voiture a remporté de nombreuses épreuves italiennes dont le Valli Imperiesi Rally avec Cambiaghi/Di Gennaro comme pilote et co-pilote, puis la Proserpina avec l'équipage Bronson/Di Prima. La carrière de la voiture s'est prolongée avec succès en 1984 avec Zanini et Autet au championnat espagnol et a gagné à six reprises, le Critérium Guilleres, les rallyes de Sierra Morena, San Agustin, Luis de Baveria, Oviedo et Vasco Navarro.

Ces Ferrari de compétition endurantes et à la brillante carrière, bien que relativement peu connues, étaient équipées de suspensions à rotules et de frein à disque améliorés, de roues Canonica avec pneus Pirelli en série, leurs pièces étant régulièrement changées et mises à niveau au cours de leur carrière en compétition. La substitution obligatoire des jantes Campagnolo par des Canonica à cinq branches, plus étroites et à l'aspect plus banal, réduisaient la voie par rapport aux voitures de Groupe 4 réservées au circuit.

Trois des 308 Groupe B Michelotto reçurent un moteur QV à 32 soupapes délivrant 310 ch à 8 000 tr/min après que ce prototype (châssis n° 18869) ait été achevé avec un moteur à deux soupapes par cylindre de 288 ch. Alors que les versions Groupe 4 recevaient une injection mécanique Kugelfisher, les voitures de rallye du Groupe B utilisaient le système d'injection électronique Bosch K-Jetronic. Ces versions Groupe B pesaient environ 30 kg de plus que les variantes circuit, car elles conservaient leurs panneaux de carrosserie en fibre de verre et acier de série.

Depuis l'achat par son actuel propriétaire., la boîte a été révisée et le plancher de coffre refait. Elle est vendue avec une carte grise française et une demande de certificat Ferrari Classiche est en cours de réalisation.

Première – et l'une des plus brillantes – de ce rare carré de Ferrari 308GTB construites par Michelotto, il s'agit d'un exemplaire particulièrement intéressant et emblématique de la race des Berlinetta Competizione Ferrari. Ancienne participante au Tour Auto, la voiture est un ticket d'entrée direct et rapide dans les prestigieuses épreuves de cet ordre et mérite qu'on la considère avec intérêt.
