1967 McLaren M4B news, pictures, and information | ||
| Tweet | ||
The McLaren M4A Formula 2 car was designed by Robin Herd and announced in early 1967. It was to be built by Lambretta-Trojan. The M4B was the Trojan production car for the American Formula B racing series. Between 1967 and 1968, there were twenty-five examples of the M4 built.
The M4B had a ten gallon fuel tank on either side of the cockpit with an additional 5 gallons in a seat back tank. The car had a bathtub monocoque formed from aluminum paneling which was attached to four steel bulkheads. The nose and cockpit were clothed in fiberglass. At all four corners were McLaren Elva cast magnesium wheels that measured thirteen inches high and seven-inches wide.
M4B F1
The McLaren M4B was designed by Robin Herd and developed from one of the M4A cars. It was McLaren's second F1 championship contender and it contested two world championship races. It also raced at several other events. Powering the M4B was a 2.1-liter BRM V8, which helped it score three points in its short-lived competition career. All of the points were scored at the second championship race at Monaco.
The M4B was an improved version of the M4A Formula Two car with a larger engine and fuel tanks. It made its racing debut in the 1967 Race of Champions at Brand Hatch. The car showed tremendous promise, but after missing a gear while shifting, Bruce had to retire prematurely from the race due to engine failure. At the Spring Trophy at Oulton Park, McLaren finished in fifth place in both heats of the race. He scored another fifth in the International Trophy at Silverstone.
The cars Grand Prix racing debut was at the Monaco Grand Prix where Bruce may have finished in either second or third had it not been a problem with the batter that caused him to pit for a new one. This cost him two places; he finished fourth.
At the next event, the Dutch Grand Prix, the M4B was outclassed by a field that was powered by a new Cosworth DFV engine. Bruce finished 14th in qualifying. One the second lap of the race, Bruce crashed out, ruining the only M4B. The car was later repaired, but it caught fire during a test at Goodwood and was written off.
For the 1967 season, McLaren introduced their next F1 contender, the M5A.

| 1970 Monaco Grand Prix: A Reversal of Fortunes | |
 | In gambling and sports there is one word that seems to be absolutely foundational to both—luck. Heading into the 1970 season Jack Brabham had had his share of luck. Jochen Rindt, on the other hand, seemed to have none of it. This would all change on the 10th of May, 1970. Jochen Rindt had come into Formula One during the mid-1960s and was certainly fast straight-away. Often one of the quickest drivers on the circuit, Rindt would find his choice of teams to be his biggest letdown as the reliab...[Read more...] |
| 2013: CELEBRATING 50 YEARS OF McLAREN | |
 | 'Life is measured in achievement, not in years alone.' When a 27-year-old Bruce McLaren penned those words in 1964, his new company, Bruce McLaren Motor Racing Ltd, was less than a year old. In those days, Bruce's vision was shared by fewer than half a dozen loyal souls, who slogged across the world to race his self-made cars. Nowadays, the McLaren Group employs more than 2000 people, all of whom still share Bruce's ideals of combining sportsmanship with solid engineering practice ...[Read more...] |
| 1967 Can-Am Road America: The Beginning of the 'Bruce and Denny Show' | |
 | While Formula One will be forever considered the pinnacle of motorsport, from a period between 1966 and 1986 there existed a series that would likely be the closest to 'anything goes' as any motor racing series could truly get. Based upon the FIA Group 7 cars but allowed to showcase unlimited engine sizes and unfettered aerodynamics, the Can-Am cars would have to be considered the pinnacle of motorsport technology and power of their era. And for more than a couple of years there would be one tea...[Read more...] |
| 1968 Belgian Grand Prix: A First for McLaren | |
 | McLaren and Formula One are truly synonymous. Over the course of its history, McLaren has completed 714 races and have garnered no less than 178 victories. But while McLaren and victory in Formula One are an almost certainty, the very first would be anything but a complete surprise. In December of 1959, Jack Brabham would be leading the way in his Cooper T51 with Bruce McLaren following along not all that far behind. The final lap of the United States Grand Prix held at Sebring, Florida has j...[Read more...] |
| 1962 Monaco Grand Prix: McLaren Carries the Cooper Flag back to the Top | |
 | By the beginning of the 1962 Formula One season Jack Brabham had left Cooper to form his own racing team. It seemed the glories days of the double World Championship were well and truly behind them. However, left in Brabham's stead would be a man very akin to the Australian in so many ways. And in Bruce McLaren, Cooper had a driver and competitor more than apt to help carry the team forward into the future. The first race of the 1962 season, the Grand Prix of the Netherlands, certainly didn't...[Read more...] |
