1964 configuration? As the original skins had AO baked into them they don't quite work, you can see that next to the rear window. Uses a CSP trick to create the Dedion rearend.
With the VAO patch that is AO on top of AO on top of AO and if you use one of the realtime AO shaders from CSP that equals 4xAO. That oughta keep at least one of my detractors happy.
version 20240629: Replaced blue carpet with plastic tarp. Blended the skins AO some, far from perfect.
version 20240710: COSMIC DeDion rear suspension with Camber and adjustable Toe.
As soon as the summary development of the TIPO 64 was completed, engineer Giulio Alfieri, responsible for the design of the racing cars, focused his attention on a new car, the 151, which was to mark the return to more classic concepts. Since a maximum displacement of 4 liters had been imposed, it was preferred to use the front engine solution, which was more congenial given the enormous power available.
ReplyDeleteThe chassis was made up of a trellis of large tubes with a mixed oval and circular section with independent front suspension and De Dion rear axle, a solution already used for the TYPE 64. As regards the engine, the initial idea of using a V12 was set aside in favor of a V8 derived from the Maserati 450S engine with a displacement reduced to just under 4000 cc. In consideration of the purpose of the car, destined above all for the 24 hours of Le Mans, a closed bodywork was used, resembling the fabulous 450 S by Zagato designed by Frank Costin which, naturally, took into account aerodynamic progress: truncated tail, imposing nose (with a conspicuous protuberance under which the air pipes of the carburettors were placed).
Due to a slight but fatal delay, the car missed the preliminary testing appointment for the 24 Hours but, shortly afterwards, the 151 was on the track in Modena with the American Walt Hansgen, who had already raced for Cunningham. In 1962 this same team entered two 151s (white with a blue central band), while a third example defended the colors of the Maserati-France team (red with a French tricolor band).
Respecting what was now consolidated practice for Maseratis, the three cars alternated a dazzling start with a disastrous retirement, due respectively to: broken piston, off-road, abnormal wear of the rear tyres. After this experience, Cunningham's machines carried out minor activity in the USA also with a 5.6 liter engine. One of them, with a 7-litre Ford engine, was destroyed at Daytona in 1963.
MASERATI 151/2
Maserati-France, which was aiming for European races, sent its 151 back to Modena to have it updated. The 151/2 was characterized, first of all, by the new 8-cylinder V engine of almost 5,000 cc. and the De Dion rear axle underwent some modifications to eliminate the tendency to deformation, a problem that also negatively affected the tires. Finally, the weight dropped further.
Although the car had much greater potential, the 1963 season was not much more positive than the previous one: retirement at Le Mans (after an excellent start to the race) with the only consolation of the class victory in the Auvergne Trophy.
MASERATI 151/3
Maserati did not lose hope and for 1964 a third version of the 151 was produced, the 151/3, with radical changes to all the mechanics and bodywork. The engine, positioned in a more rational way, allows the bonnet, the transmission and, consequently, the entire car to be lowered.
The tail, on the contrary, had become very imposing and high. The external dress, in particular, designed by Piero Drogo, made it resemble (and was the cause of its themed nickname) a real racing van.
Such aerodynamics, applied to such a fast car, created quite a few handling problems, which were averted in time for the 24 Hours of Le Mans: for 5 hours the 151/3 managed to fight on equal terms with Ford and Ferrari before withdraw due to breakdown of the electrical system. The same problems recurred at the 12 Hours of Sebring and the Mille Chilometri in Paris, confirming the insurmountable handicap suffered by the Maseratis entrusted to private teams and present in too few numbers.
ReplyDeleteMASERATI 151/4, THE MELANCHOLIC END
With an obstinacy worthy of a better cause, in 1965 Maserati's efforts led to a renewed 151, known as Progetto 154 or 151/4. The engine was further enlarged to 5,046 cc and was accompanied by further updates to the bodywork and chassis.
Once again entrusted to Maserati-France, the car was entered in the 24 hours of Le Mans. But during testing the only example available to the team, entrusted to Lloyd "Lucky" Casner, went off the track on the Mulsanne straight due to the wet asphalt. The car, uncontrollable, began a terrifying carambola with numerous rollovers that completely destroyed it. No hope for poor Casner.
The only surviving component, the 8-cylinder engine, was installed in the Maserati Tipo 65 two months later but, in the meantime, Maserati had decided to definitively say goodbye to the production of GT racing cars.

Neat, thank you. I think the body I modelled ran in 1964 at some time, although I also see photos with a window in the top as well as the back.
DeleteIt was the version they brought to scrutineering but they were told the window wasn't sufficient so go make it bigger.
DeleteI bow my head to your art, a real pleasure to drive this car.
ReplyDeleteThe big rear windowed (Trintignant) Version run in Le Mans. I edited your version with new AO+map inside + outside, made headlight glass, new inner blue fabric like the original and here is the link https://www.mediafire.com/file/1t2dmgfr1dd102h/maserati_tipo_151_drogoedit_mr.Hunt.rar/file please test it, if its fine and i wrote you at the planet
