Arrested Development - McLaren M26/1

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.



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.



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.



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.



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.



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.



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.



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.



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 !§

Tribute to Ronnie - March 71B - 08

Resting in the entrance to Colin Bennett's CGA Engineering in Warrington a couple of Saturdays ago was this March 71B belonging to Katsu Kubota a 'gentleman driver' who admires one of my heroes Ronnie Peterson.



The car is painted in the colours used by Ronnie Peterson when he drove a similar car in 1971 to win the European Formula 2 Championship, a second tier open wheel series for cars powered by engines up to 1600 cc / 109.9 cui.



Ronnie frpm Almby in the vicinity of Örebro, Sweden, secured the championship with four wins at Rouen, Mantrop Park, Flugplatz Tulln-Langenlebarn, Vallelunga and took five pole positions. Ronnie also secured second place in the World Drivers Championship in 1971.



The ambitious March team took it's name from founders Max Mosley, Alan Rees, Graham Coaker and Robin Herd, in 1969 they built a Formula 3 third tier open wheeler and the following year decided to take the racing world by storm by manufacturing vehicles to compete in Formula 1, Formula 2, Formula 3, Formula Ford and Can-Am for customers to race, while also running factory teams in the Formula 1, Formula 2 and Formula 3 open wheel series. Jochen Rindt originally agreed to race the works Formula 1 car but backed out when he realised the scale of the March undertaking outside Formula 1.



This 71B was originally built to take part in Formula Atlantic races in 1971, Formula Atlantic also known as Formula B in the USA was a halfway house between Formula 3 and Formula 2 powered by 1600 cc / 109.9 cui motors that were not in such a high state of tune as either Formula 3 or Formula 2 and therefore much cheaper to run. The 71B chassis has many components that are interchangeable with the March 713 and 712 chassis built for Formula 3 and Formula 2 respectively.



At present I know nothing about the history of chassis 71B - 08 prior to Mr Kubota's ownership if you did please chime in below or send me an e-mail, my e-mail address can be found in my 'Blogger' profile.



I understand wooden gear stick knobs are popular in the racing community because they save weight, the Porsche 917 famously used a gear stick knob made of balsa wood.



The motor fitted to Mr Kubota's March is an out of period 1,975 cubic centimetres /120.5 cui Ford Cosworth BDG 4 cylinder unit with an aluminium cylinder block of a type that was sanctioned in Formula 2 from 1972.



Last year Mr Kubota became the first driver from Japan to win an FIA sanctioned Formula One race in the Historic Formula One series, this year he will also race the genuine March 761/06 as raced by Ronnie Peterson to victory in the 1976 Italian GP, a car that will appear in a future blog once I have seen it run later in the summer.

My thanks to Colin Bennett for having me and several members of The Nostalgia Forum visit his fascinating workshop and to Tony Gallagher for organising the trip.

Hope you have enjoyed today's Tribute to Ronnie Peterson edition of 'Gettin' a lil' psycho on tyres' and that you will join me again tomorrow. Don't forget to come back now !
