Third Time Lucky – McLaren Ford M7A

After the disappointments of the Ford Indy derived V8 and Serenissima V8 used in the 1966 McLaren M2B, the interim BRM V8 Formula 2 based McLaren M4B and BRM V12 powered M5A of 1967 Bruce Mclaren bought 5 Ford Cosworth DFV motors for the 1968 season which were used as in the integral structure of the McLaren M7A designed by Robin Herd, Gordon Coppuck and Bruce himself.

The M7A’s and 3 derivatives, M7B, M7C, and Alfa Romeo powered M7D were entered by the works team from 1968 to 1970. For 1968 the works Formula One McLaren’s were sponsored  by Shell while the McLaren Can Am Cars were sponsored by Gulf.

Reigning World Champion Denny Hulme left Brabham to join McLaren in 1968 and on the M7A’s debut at the non Championship Race of Champions at Brands Hatch Bruce came first and team mate Denny Third. The M7A’s came in first and second at the non Championship International Trophy at Silverstone with Denny Hulme came edging the team founder.

On their third championship appearance, after Spain and Monaco, Bruce McLaren became the second man to win a Grand Prix bearing his own name crossing the line first to win the 1968 Belgian Grand Prix. It would prove to be his forth and final Grand Prix victory.

Denny Hulme won the Italian and Canadian Grand Prix towards the end of the season and finished third in the World Drivers Championship behind Graham Hill and Jackie Stewart, Bruce finished fifth in points standings. McLaren finished second in the constructors Championship behind Lotus but ahead of the Ken Tyrrell entered Matra driven by Jackie Stewart all three constructors used Ford Cosworth DFV motors.

In 1969 Bruce only drove an M7A in South Africa where he finished fifth before focusing on the M7C, which will be the subject of a future blog, which featured a more substantial monocoque. Denny meanwhile continued driving the M7A throughout the 1969 season winning the season finale in Mexico. Denny finished the season 6th in points with Bruce 3rd, the Mclaren team finished 4th and last of the Ford Cosworth DFV powered teams in the constructors championship.

The M7B fitted with outrigged panier fuel tanks made only one works championship appearance at the 1969 South African Grand Prix where Bruce Mclaren finished 5th. He later sold the car to Colin Crabbe who’s Antique Automobiles team entered it in four races for Vic Elford who finished a best fifth in the 1969 Dutch Grand Prix.

In 1970 McLaren adapted an M7 to take a non stressed Alfa Romeo V8 which became known as the M7D the car recorded three DNQ’s, did not qualify, a not classified finish in France and a DNS, did not start, in the 1970 British Grand Prix. After the first four events Nanni Galli took over the M7D from Andrea de Adamich, recording the cars third DNQ at the Italian Grand Prix.

Privately entered M7A were driven in three races by Dan Gurney for All American Racers in 1968, best finish forth in the US Grand Prix, and Basil van Rooyen for Team Lawson in the 1969 South African Grand Prix where he retired with brake problems after completing 12 laps.

Thanks for joining me on this “Third Time Lucky” edition of ‘Gettin’ a lil’ psycho on tyres’ I hope you will join me again tomorrow. Don’t forget to come back now !

06/07/13 Errata as Tim has pointed out below Bruce finished the 1960 season second in the World Drivers Championship and so his 3rd place in points in 1969 did not equal his career best as originally stated. Apologies for any confusion.

Choice Of Champions – Lotus 49B #R10 & #R12

The story of the Lotus 49 in all of it’s guises is inextricably linked to the one component that was a decade ahead of it’s time the Ford DFV motor, which did not win it’s last race until 1983 and was still being used in 1985 running against turbocharged powered cars.

Lotus 49B, Goodwood, FoS

The Lotus 49 was originally built to compete in the 1967 Formula One season for drivers Jim Clark and Graham Hill. Colin Chapman had arranged for Ford to finance the building of the 3 litre / 183 cui Ford Cosworth V8 engine which like the BRM H16 Colin had used in 1966 was to be used as an integral component of the chassis, ie, if you take the motor out of the car the rear wheels would no longer be connected to the rest of the car sufficiently to be able to even push it.

Lotus 49B, Goodwood, FoS

The Lotus 49 design, credited to Maurice Phillipe, was based on the 1965 Indy winning Lotus 38 which Len Terry is credited with being responsible for. Jim Clark drove the Lotus 49 to a debut win in the 1967 Dutch Grand Prix. The Type 49 in all it’s guises won 12 Grand Prix in total the last a lucky last lap win at the 1970 Monaco Grand Prix with Jochen Rindt at the wheel.

These air ducts, introduced on the 49B in 1969, allowed air to pass through the radiator and escape over the top of the car, where as on the original car the air had passed through the nose cone and out the sides of the car ahead of the front suspension units.

Lotus 49B, Goodwood, FoS

Producing around 400 hp when it first became available, Colin Chapman had an advantage over every other car in the field with the light and reliable Cosworth DFV which had years of development ahead of it that would see it’s output reach just short of 500 hp in 1985. Unfortunately, for Colin Chapman, realising that they needed to be seen running against other competitive teams Ford renegade on it’s exclusive deal with Lotus at the end of 1967 and allowed Ken Tyrrells Matra team to use Ford engines as well in 1968. By the mid 1970’s only Ferrari and BRM were the only regular runners not using Cosworth DFV’s.

Lotus 49B, Donington Park Museum

In 1968 Brabham and Ferrari copied the high aerofoil concept first seen on the Chaparral 2E Can Am car in 1966 and on the 1967 Chaparral 2F in the World Prototype championship, a month later the Lotus 49B with new rear hubs to carry the 400 lbs of downforce generated by the rear wing appeared at the French Grand Prix.

Lotus 49B, Donington Park Museum

This photo shows clearly how big an issue rear grip was back in 1968 not only is their a rear wing but the Hewland gearbox is surrounded by a large oil tank in an effort to distribute as much weight to the rear of the car as possible to improve road holding.

Lotus 49B, Donington Park Museum

The inverted aeroplane wing shape and light construction of the rear wing can be seen here, in 1969 similar wings were attached to the front hubs as well, but two bad accidents caused by collapsing wings for Lotus Team mates Graham Hill and Jochen Rindt led to these devices being strictly controlled from the 1969 Monaco Grand Prix on.

Lotus 49B, Donington Park Museum

So far as I can tell the chassis seen here, in the first, second and forth photo’s, at Goodwood is #R10. Chassis R10 was probably the original 49 #R5 which for reasons that are not clear was renumbered.

While carrying the #R5 chassis plate the car was raced in his second world championship winning year by Graham Hill to win the 1968 Monaco Grand Prix, #R10 was subsequently used by 1978 World Champion Mario Andretti to win pole for his first Grand Prix start in the 1968 US Grand Prix at Watkins Glen.

Future 1970 champion Jochen Rindt was the first to use running with a 2.5 litre / 152.6 cui version of the Ford Cosworth DFV. Jochen won two Tasman Championship races in #R10.

Reigning 1968 World Champion Graham next used #R10 to win the 1969 Monaco Grand Prix. The following season Graham was driving the Lotus 49 #R7 for the privateer Rob Walker team which he crashed beyond immediate repair during practice at Monaco. Fortunately Lotus number 2 driver John Miles had failed to qualify for the race in #R10 and so it was hastily repainted in Rob Walkers colours the night before the race for Graham to drive. He finished 5th despite having broken his legs in the 1969 season ending US Grand Prix driving the same chassis just 7 months earlier !

1972 & 1974 double world champion Emerson Fittipaldi made his Grand Prix debut in Lotus Ford 49 #R10, at the British Grand Prix in 1970.

Finally the first race I ever recall seeing on TV was the 1968 British Grand Prix which was led by first Graham Hill, then his team mate Jackie Oliver before being won by Jo Siffert all three were driving Lotus 49 B’s Jo’s being the odd one out being entered by Rob Walker, who GALPOT regulars may recall had a lot of success running Stirling Moss in his Lotus 18 during the early 1960’s. Jo’s victory was the last to be recorded by a private entrant in a ‘customer’ non works customer car.

24 04 12 PS Tim Murray has kindly pointed out that I originally incorrectly attributed the design of the Lotus 49 to Len Terry when it should have been Maurice Phillipe, apologies for any confusion. If you see an error of fact anywhere in GALPOT blogs please do not hesitate to inform me in the comments box. Thanks to Tim for the correction.

03 08 12 Serious Errata further reading of Micheal Olivers “Lotus 49 the story of a Legend” has shown that the car which is seen in the 3rd, 5th, 6th and 7th photo’s above at the Donington Collection is actually chassis #R12 and not chassis #R10 as seen in the 1st, 2nd 4th photo’s above, there are several distinguishing features which should have made this obvious at the time I originally posted this blog including the black ‘Lotus Ford’ lettering on the nose various decals and the chrome exhaust at the rear !

Chassis R12 was built up as a show car, for the Ford Motor Company, using the floor from the Lotus 49B R6/1 which was crashed by Jackie Oliver at the 1968 French Grand Prix. Built as a non runner chassis #R12 is consequently the only Lotus 49 which has never been raced, it was donated to Tom Wheatcroft’s Donington Collection when Ford no longer had a use for it.

Sincerest apologies for this error.

Arrested Development – McLaren M26/1

McLaren M26, Silverstone

The McLaren M23 was already a four year old design when Gordon Coppucks successor the lower and lighter McLaren M26 was launched in the summer of 1976.

McLaren M26, Silverstone

Unfortunately the development of the M26 was almost immediately stifled as James Hunt in his M23 and the team were waging one of the fiercest championship battles in the history of the World Divers Championship to that point in time.

McLaren M26, Silverstone

The M26 did race at the Dutch Grand Prix driven by Jochen Mass in 1976 but it was quickly decided that the design needed serious development that was best postponed until the end of the season.

McLaren M26, Silverstone

James subsequently won the 1976 World Drivers Championship. I am not sure why the M26 was not ready for the start of the 1977 championship but the older M23 was pressed into a fifth season of competition and it was not until the 10th round of the 17 race Grand Prix schedule that both front line McLaren drivers James Hunt and Jochen Mass had the M26 available to race.

McLaren M26, Silverstone

Nearly a year after it was launched, now featuring a radiator mounted in the nose, the car was competitive and at the British Grand Prix in 1977 James recorded the first of three victories driving the M26 model, not enough to defend his World Drivers championship but a respectable achievement none the less.

McLaren M26, Silverstone

James was not known for his testing skills in the same way as the much vaunted Niki Lauda and so it is perhaps no surprise that for the following 1978 season the development of the M26 did not significantly improve performance.

McLaren M26, Silverstone

In 1978 the M26 was, like most of the opposition, simply outclassed by the dominant Lotus 79 design which introduced hitherto unimaginably superior handling to Grand Prix racing thanks to the venturi in it’s side pods. Hunt left the McLaren Team to rejoin former Hesketh designer Dr Harvey Postlethwaite at Wolf Racing for the 1979 season.

McLaren M26, Silverstone

The car featured in these photographs is thought to be chassis M26/1 which was first raced by Jochen Mass in Holland in 1976. The best result for M26/1 was fourth place scored by Jochen Mass behind winner James Hunts similar model at the 1977 British Grand Prix.

McLaren M26, Silverstone

The vehicle is seen here being driven by owner Frank Lyons is expected to take part in this weekends Silverstone Classic race for Formula One cars on Sunday.

My thanks to NZALPA, VINCE H, David Lawson, Tim, Murray, Tony Gallagher, Alan Cox, Pink Snail, David Lawson, hipperson and Geoff Butcher at The Nostalgia Forum for their help identifying the chassis number and driver.

Hope you have enjoyed the Arrested Development edition of ‘Gettin’ a lil psycho on tyres’ and that you’ll join me again for a look at a Fittipaldi in Wolf clothing tomorrow. Don’t forget to come back now !

Caution Wide Vehicle – McLaren M23 M23/6

McLaren M23, Donington

The Ford Cosworth DFV powered McLaren M23 was designed by Gordon Cuppock, based on the lessons learned from the successful McLaren M16 Indy car. The M23 driven by Denny Hulme burst onto the Grand Prix scene in 1973 with a pole position on its debut in South Africa. Denny scored the first win for the model in Sweden and Peter Revson followed that with wins in Great Britain and Canada in 1973.

For 1974 Denny who won his last race in an M23 in the season opening Argentinian GP was joined in the McLaren team by 1972 World Champion Emerson Fittipaldi who won in Brazil, Belgium, and Canada on his way to becoming the 1974 World Champion. McLaren also won the World Constructors title in 1974.

Jochen Mass joined Emerson in the McLaren team in 1975 winning the shortened Spanish GP while Emerson won in Argentina and Great Britain to finish 2nd in the World Drivers Championship.

1976 would prove to be the chassis most successful year in terms of wins with James Hunt, who replaced Emerson in the team crossing the line first in Spain, France, Great Britain, Germany, The Netherlands, Canada and the United States.

However 1976 was a year of high drama and comedy in Formula One first James was disqualified from the Spanish Grand Prix because his car was 1.8cm less than an inch too wide. In 1975 the McLaren had been used as a base model too set the dimensions for the 1976 Formula regulations.

McLaren successfully argued that when the tyres on the car were moving they were taller as a result of the centrifugal force taking up the slack on the side walls of the tyres and that this accounted for the discrepancy. The governing F.I.A. accepted this argument and the win was reinstated with a $3,000 fine, when the M23’s next appeared they had a slightly narrower rear track.

On the first corner, Paddock Bend, of the opening lap of the British Grand Prix James Hunt was the innocent victim in a crash with Ferrari’s Clay Reggazoni. The race was stopped and James who’s car was severely damaged took a short cut to get back to the pits when the race was stopped.

Come the restart the organisers initially refused to allow James to line up on the grid because the team had worked to repair his car while the mess was being cleared up. However people power intervened and fearing a riot from the partisan crowd the organisers relented, James took the win, he and the partisan crowd partied long and hard into the night and later the F.I.A. disqualified both Hunt and Clay Regazzoni from the event for having failed to complete the opening lap.

Up until this point reigning Champion Niki Lauda had dominated the 1976 Championship with four wins three seconds, the last of which became 1st after Hunt’s disqualification from the British GP and a third. The next race was the ill feted German Grand Prix in which Niki was eliminated in an accident that triggered an inferno from which he was lucky to escape with his life.

James won the German Grand Prix and the Dutch GP while Niki recuperated and 39 days after the inferno at the Nurburgring Niki and James met again at the Italian GP. At the end of practice for the Italian GP James and Mclaren team mate Jochen Mass and John Watson at Penske were found to be running with a fuel octane rating that was too high and had their Saturday times disallowed.

Since it had been raining during the first practice sessions on the Friday Hunt, Mass and Watson had effectively failed to qualify, however the 13 second plus off pace Otto Stuppacher was already on his way home to Austria when the announcement and the Marlboro sponsored Art Mezario withdrew as did Englishman Guy Edwards allowing Hunt, Mass and Watson to start.

Hunt crashed trying to make time and was applauded for doing so by the Tifosi and Lauda came home a remarkable 4th in his first race back.

James won both the Canadian and US Grand Prix while the brave Niki could only amass a further three championship points. Going into he last race of the season the Japanese GP Niki had a 3 point lead over James.

For the race James qualified 2nd behind Andretti with Niki just one place further back. I remember getting up at some unholy hour to watch this race live on TV in the UK and remember the disappointment when I saw the monsoon that unfolded on the track.

After much debate amongst the driver the race started and Niki who had lost his eyelids in the German inferno and yet to have them replaced through plastic surgery had little choice but to retire in the near zero visibility conditions. James took an early lead in the race but as the rain stopped and the track started to dry Hunt started losing ground dropping to 5th after a pit stop to replace a punctured tyre with just a few laps to go.

James charged back into the race managing to regain two positions which left him in third position when the flag came out for Mario Andretti to win by just over a lap from Patrick Depailler, with James Hunt, who had no idea what his position was in the race, right on his tail.

Hunt only learned that he had become champion after he got out of the car and stopped shouting at team manager Teddy Meyer for a less than perfect pit stop.

Hunt won the 1976 World Drivers title by just one point and Great Britain had it’s first World Champion since Jackie Stewart had won his last crown in 1973.

The McLaren M23 was pressed into service again in 1977 but its competitiveness was on the wane James winning a non championship race before committing fully to the M26 successor which had gone through a troublesome one year gestation period before coming on song.

The works M23 had a final swan song when it introduced Gilles Villeneuve to the world of Grand Prix racing in Great Britain and Bruno Jack’O’Malley in Italy towards the end of the 1977.

I have done my best to find out exactly which of the 13 M23 chassis this is, The Donington Museum blurb identified this car as McLaren M23/8 and said it was used to win the ’76 Spanish and US GP’s however M23/8 was destroyed in 1975. The car was then given a new tub with the chassis number M23/8-2 and the old tub was apparently eventually repaired to 1975 tall airbox spec and now resides in the United States.

M23/8-2 went on to become one of the stars of the 1976 season being used to win the controversial Spanish GP along with those in Canada and the US GP. M23/8-2 is said to belong to BCE the man responsible for running the the whole Formula Show since 1981.

It is said that the vehicle in my photograph appeared at the 60th Anniversary celebrations of the World Grand Prix Drivers Championship in Bahrain last year, it is also suggested that the M23 which appeared at Bahrain belongs to the brave octogenarian who started a modelling career with Hublot earlier this year however I have no firm evidence of the ownership of the vehicle in the photograph at the top of this post
at this time.

Most likely the vehicle above seen at the Donington Park Museum is M23/6 which seems to meet many of the criteria hinted at on various threads of The Nostalgia Forum and who’s whereabouts is listed as unknown by the respected Old Racing Car site.

M23/6 was used by Denny Hulme to win the Agentine Grand Prix in 1974 then in 1976 James Hunt drove it to win the French Grand Prix, cross the line first in Great Britain only to be disqualified .

At the next race the German Grand Prix I saw James win in this chassis which became one of a rare set of vehicles that crossed the line first in three consecutive races, though it was disqualified from one of them.

In 1977 Emilio de Villota drove M23/6 with little success in Grand Prix events, 2 starts three DNQ’s, but did win two rounds of a British series open to all single seat racing cars.
