Last New 4.5 Litre – OSCA 4500G

Ten years after selling the company bearing their name to Adolfo Orsi in 1937, and remaining for those ten years as employees of the company, the Maserati brothers founded Officine Specializzate Costruzioni Automobili – Fratelli Maserati SpA better known as O.S.C.A in 1947.

Towards the beginning of the 1951 Grand Prix season Prince Bira had one of his three year old Maserati 4CLT/48’s fitted with a new 4.5 litre OSCA 60º V12 motor that produced 330hp to replace the regular 1.5 litre 4 cylinder supercharged motor.

The Prince recorded a debut win with the new motor in the Richmond Trophy at Goodwood and raced with it on at least four further occasions scoring a best 4th in the 1951 Bordeaux Grand Prix concluding his season with a retirement from the 1951 World Drivers Championship Spanish Grand Prix after completing just 1 lap with engine failure.

A little over a month before the Spanish Grand Prix O.S.C.A turned out with their own Formula One challenger, today’s featured 4500G powered by the same type of alloy block V12 as they had supplied to Bira.

Franco Rol qualified 18th of the 21 starters for the 1951 Italian Grand Prix and completed all but 13 laps of the full distance to be the last classified finisher, in a career high, 9th place.

In the absence of sufficient commitment from manufacturers to continue with the 1.5 litre / 91.5 cui / supercharged / 4.5 / 274.5 cui litre normally aspirated Formula One powered cars, the 1952 and ’53 World Drivers Championships were decided by running the series for 2 litre / 122 cui Formula Two cars.

Consequently the last all new type to appear in the 1951 Formula One championship season and the only car built specifically to compete in Formula One races by the Maserati brothers remains the OSCA 4500G seen in these photographs at last years Silverstone Classic being driven by Stephan Rettenmaier.

Five F1 Classics – Silverstone Classic

In the last of this series celebrating the Silverstone Classic Silver Jubilee this edition of “Gettin’ a li’l psycho on tyres” looks at five decades of Formula One cars.

OSCA G4500, Stephan Rettenmaier, Silverstone Classic,

Last year one of the highlights of the Maserati Centenary Trophy was seeing Stephan Rettenmaier exercising the 1951 V12 OSCA G4500, the only purpose built Formula One car built by the Maserati brothers, as opposed to the company bearing their name.

Lotus 25, Silverstone Classic,

Above Bob Dance far right is seen above fettling Andy Middlehurst’s #25 Lotus 25 chassis #R4, just as he did for Jim Clark over 50 (fifty) years ago.

March 2-4-0, Jeremy Smith, Silverstone Classic,

The March 761 was never raced in 2-4-0 configuration as seen above driven above by Jeremy Smith, but it probably helped nurture the interest of many a Scalextric racer into fully fledged Formula One fan.

Williams FW 08, Richard Eyre, Silverstone Classic,

In my humble opinion a Ferrari driver should have won, a Renault driver could have one drivers championship but a well deserving Williams driver Keke Rosberg did win the 1982 Formula One Drivers championship, driving an FW08 like the one seen with Richard Eyre at the wheel above, a six wheel version of the FW08 was also tested in 1981.

Benetton B192, Silverstone Classic,

Finally this year will see the appearance of Legends of Modern Formula One demonstrations featuring cars from the 3.5 litre Formula One era like Lorina McLaughlin’s ex Micheal Schumacher championship winning Benetton B192 seen above at the Silver Jubilee Silverstone Classic Press Day.

Entry to Silverstone Classic is by pre booked tickets only which are available from the website linked here.

Thanks for joining me on this “Five F1 Classics” Edition of “Gettin’ a li’l psycho on tyres” I hope you will join me again tomorrow. Don’t forget to come back now.

Maserati Racers – Silverstone Classic

Last weekends Silverstone Classic included a centenary celebration of the Maserati marque and here are six of the racing cars that were part of the event.

Maserati 250S, Bond, Silverstone Classic

I understand only 3 cars were built by Maserati to 250S specification and that the car seen here driven by Stephen Bond may be the prototype the only one of the three to have started life as a Maserati 200S before being fitted with the larger displacement 2.5 litre / 152 cui motor.

Maserati 300S, Silverstone Classic

I’m fairly certain the vehicle above is a Maserati 300S but which one of the 26 built and who is in it I have yet to find out since it appears to have been a late entry, if you happen to know which car this is please do not hesitate to chime in below.

Maserati 250F, Silverstone Classic

One of the most interesting vehicles at Silverstone was the white Maserati 250F chassis 2521, seen above, which is as it appeared in the 1959 German film “Ein Engel auf Erden” An Angel On Earth also known as Highway to Heaven which I have never heard of before but from this youtube clip appears to be a romantic comedy set in the Cote d’Azur with Romy Schneider in the role of an angel.

Cooper Maserati T51, Wilson, Silverstone Classic

Christopher Wilson was driving one of two 1959 Cooper Maserati T51’s entered in the Jack Brabham Memorial Trophy for pre 1966 Grand Prix cars.

Maserati A6GCM, de Baldanza, Silverstone Classic

I looked at Julia de Baldanza’s fabulous Maserati A6GCM last week.

OSCA G4500, Rettenmaier, Silverstone Classic

In 1947 the Maserati brothers founded Officine Specializzate Costruzioni Automobili – Fratelli Maserati SpA better known as O.S.C.A and this is their 1951 G4500 formula one challenger which is known to have raced at least once in the 1951 Italian Grand Prix where Franco Rol was classified 9th 13 laps down after starting 18th, Stephan Rettenmaier is seen at the wheel here.

Thanks for joining me on this “Maserati Racers” edition of “Gettin’ a li’l psycho on tyres” I hope you will join me again tomorrow when I’ll be looking at some of the French Cars at Silverstone Classic. Don’t forget to come back now !

OSCA MT4 2AD, Ironstone Winery Concours d'Elegance

Neighbours Shadows – Ironstone Concours d’Elegance.

Today’s blog comes courtesy of Geoffrey Horton who took part in the Ironstone Concours d’Elegance back in September.

OSCA MT4 2AD, Ironstone Winery Concours d'Elegance

Among the cars saw was this 1955 OSCA MT4, built by the Maserati brothers once they were free of obligations to the company bearing their own name, said to have been raced on the West Coast from 1955 to 1957.

Ferrari Dino 196 S Recreation, Ironstone Winery Concours d'Elegance

Just over two years ago I learned about a mystery batch of recreations of Ferrari 196 S V6 powered sports cars, it appears the Dino V6 seen here might belong to another car from that mystery batch.

Shadow Chevrolet Mk II, Ironstone Winery Concours d'Elegance

At Ironstone Geoffrey was pleasantly surprised to learn that Dennis Losher who restored this wonderful 1971 Shadow Mk II I looked at last summer is a near neighbour.

Losher & Horton, Ironside Winery Concours d'Elegance

Dennis on the left above and Geoffrey right appear to have become friends.

Shadow Dodge DN6, Ironstone Winery Concours d'Elegance

Above another car restored by Dennis is the 3rd of 3 Dodge powered Shadow Formula 5000 open wheel cars that raced in the USA from 1975 to 1976. This car #DN6-3A is said to have been raced by the legendary Welshman Tom Pryce in the inaugural 1975 Long Beach Grand Prix and at Riverside by future 1979 World Champion Jody Scheckter, from South Africa, races from which both drivers retired with gearbox and engine problems respectively.

My thanks as always to Geoffrey for sharing his photographs.

Thanks for joining me on this “Neighbours Shadows” edition of “Gettin’ a li’l psycho on tyres”, I hope you will join me again tomorrow.

Sister doing it for her self – OSCA Tipo S-187

Today we return to Lime Rock in 1959 courtesy of Ed Arnaudin for a look at this OSCA Tipo S-187 belonging to Briggs Cunningham.

Officine Specializzate Costruzioni Automobili – Fratelli Maserati SpA was set up by the three racing mad Maserati brothers Ernesto, Ettore and Bindo after their involvement with the company bearing their own name had concluded with it’s sale to Adolfo Orsi in 1937 and the expiry of their subsequent 10 year consulting contracts in 1947.

The brothers focused on building extremely successful sports cars primarily with engines of 750 cc / 45 cui to 1500 cc / 91.5 cui. Cunningham’s car seen here appears to be one of 17 Tipo S-187’s built from 1956 – 1960 with a 70 hp 749 cc / 45 cui twin cam engine with a, for the time, high 9:1 compression ratio.

The real story behind the #23 OSCA on this day in 1959 however is the driver who took the car to victory lane, one D McCluggage from Kansas, who is well known for breaking down discriminating and prejudicial barriers in journalism and at the race track, simply D stands for Denise.

As well as regularly whooping all the boys on the race track she is a seasoned motor sports journalist who was famously sent to Indianapolis by The Herald Tribune only to find she was barred from the press box, pit lane AND garage area, unperturbed she got her story from elsewhere round the track and published anyway.

Phil Hill later described the prevailing attitude at the time “It’s a bit embarrassing to me, given today’s enlightened attitudes, to admit that in the late 50s I was a bit disturbed by the idea of this woman driver. It wasn’t a matter of feeling threatened, but like many men in that period, I had trouble understanding what kind of statement Denise might be making with her driving efforts. The fact is, gender stereotypes aside, she was holding her own on the track.”

All Denise wanted to do was win and she did often, after her career as a professional driver was over she became a founding light at AutoWeek where her accomplishments are still scene as an example for others to follow.

Denise recently became the only Journalist to ever be inducted into the Automotive Hall of fame and at over 70 she still writes her ‘Drive, She Said’ column syndicated in over 90 newspapers across the US and Canada.

Hat’s off to Denise gentleman, for waking us up to our equals !

Thanks to Steve and Ed Arnaudin for the photograph, and to Terry O’Neil for the race day information.

Hope you have enjoyed today’s prejudice free edition of ‘Gettin’ a lil’ psycho on tyres’ and that you’ll join me tomorrow for a look at a splendid vintage Triumph Dolomite. Don’t forget to come back now !
