The Legacy of Cosworth: A Unique Chapter in Formula 1 History<\/p>\n

Cosworth is a name synonymous with success in the world of Formula 1, particularly during the late 1960s and 1970s. The company, initially a small engineering firm, revolutionized the sport with its DFV V8 engine, which dominated the racing scene for over a decade. However, what many fans may not know is that Cosworth also ventured into the realm of car design, creating its own unconventional F1 car that showcased innovative engineering and a bold vision for the future of racing.<\/p>\n

The Origins of Cosworth’s Ambition<\/p>\n

Founded by Mike Costin and Keith Duckworth, both of whom had backgrounds as engineers at Lotus, Cosworth’s rise to prominence began with the DFV engine, which was funded by Ford. This engine not only powered numerous championship-winning cars but also became a symbol of British engineering prowess. The story of Cosworth, however, is not just about engines; it also encompasses a daring attempt to design a race car that would challenge the norms of Formula 1.<\/p>\n

In July 1969, Cosworth unveiled its unnamed F1 car, which was the brainchild of Costin, Duckworth, and Robin Herd, a design engineer who had previously worked on the Concorde project. The car was described as \u201csomething entirely new in single-seater aerodynamics, structure, and the detail arrangement of the transmission.\u201d This ambitious project aimed to harness the power of four-wheel drive (4WD), a concept that had been explored in the sport but had yet to be fully realized.<\/p>\n

The Promise of Four-Wheel Drive<\/p>\n

The potential of 4WD in Formula 1 was not a new idea. As early as 1961, Stirling Moss had demonstrated the advantages of a 4WD system in a non-championship race, showcasing its ability to manage the immense power of F1 engines, which had surpassed 400 bhp. The introduction of 4WD was seen as a solution to the challenges of traction and control, particularly as cars became faster and more powerful.<\/p>\n

Lotus had made strides in this area, nearly winning the 1969 Indianapolis 500 with a gas-turbine 4WD car. Drivers like Jackie Stewart praised the benefits of 4WD, noting that it allowed for better balance and quicker cornering, ultimately leading to faster straight-line speeds. With such promising feedback, it was clear that 4WD could revolutionize the dynamics of racing.<\/p>\n

Cosworth’s Unique Approach to 4WD<\/p>\n

While other teams like BRM, Lotus, and Matra integrated existing 4WD systems into their designs, Cosworth took a different route. The company developed its own innovative system, which featured a two-shaft gearbox and a unique torque-split ratio of approximately 40:60 between the front and rear wheels. This design allowed for adjustments by changing the diameters of the front and rear wheels, providing a level of customization that was unprecedented at the time.<\/p>\n

The engineering behind the Cosworth 4WD car was intricate. The layout of the drive system was designed to eliminate unnecessary components, such as idler wheels, which were common in other designs. This streamlined approach not only reduced weight but also enhanced efficiency, showcasing Cosworth’s commitment to pushing the boundaries of automotive engineering.<\/p>\n

Challenges and Setbacks<\/p>\n

Despite its innovative design, the Cosworth 4WD car faced significant challenges on the track. Other teams experimenting with 4WD, such as Lotus and Matra, encountered difficulties that led to negative feedback from drivers. Jochen Rindt, a leading driver for Lotus, famously refused to race the 4WD 63 due to his discomfort with its handling. Similarly, Bruce McLaren described his experience with the M9A as akin to \u201csigning your name with someone pushing your hand along,\u201d highlighting the struggles drivers faced with these new technologies.<\/p>\n

Ultimately, the Cosworth 4WD contender never made it to a race grid. By August 1969, it was concluded that \u201c4WD in F1 has been something of an anti-climax.\u201d The complexities of integrating 4WD into the high-speed, high-stakes environment of Formula 1 proved too daunting, and the concept was largely abandoned, with only a single experimental appearance by Lotus in 1971.<\/p>\n

The Enduring Impact of Cosworth’s Vision<\/p>\n

While the Cosworth 4WD car never achieved the success its creators envisioned, its legacy endures as a testament to innovation and ambition in motorsport. The story of Cosworth reflects the spirit of engineering excellence that has characterized Formula 1 for decades. It serves as a reminder that the pursuit of technological advancement often involves risks and setbacks, but it is through these challenges that the sport continues to evolve.<\/p>\n

As we look back on this unique chapter in Formula 1 history, it is essential to recognize the contributions of Cosworth not only as an engine manufacturer but also as a pioneer in race car design. Their efforts to explore the potential of four-wheel drive may not have changed the course of racing, but they certainly added depth to the narrative of innovation in motorsport.<\/p>\n","protected":false},"excerpt":{"rendered":"

\"Cosworth<\/a><\/p>\n

Cosworth’s engines dominated F1 in the 60s and 70s \u2013 but it also made its own unconventional race car<\/p>\n

\n

Cosworth became famous the world over in the late 1960s as its Ford<\/a>-funded \u2018DFV\u2019 V8 engine totally dominated Formula 1 <\/a>\u2013 something it would continue to do throughout the 1970s.<\/p>\n

In fact, its final grand prix win didn\u2019t come until 1983. It\u2019s one of the most admirable of the many \u2018blokes in a shed beat all the car industry giants\u2019 stories Britain produced in the last century. It\u2019s not well known, though, that Cosworth <\/a>at this time created not only its own F1 engine but its own F1 car \u2013 and a highly unconventional one at that.<\/p>\n

This unnamed racer was dreamed up by Cosworth co-founders Mike Costin and Keith Duckworth, both former Lotus <\/a>engineers, and Robin Herd, who started his career as a design engineer on Concorde,\u00a0and then designed McLaren\u2019s<\/a>\u00a0first-ever grand prix winner.<\/p>\n

\u201cIt is something entirely new in single-seater aerodynamics, structure and the detail arrangement of the transmission,\u201d we reported on its July\u00a01969 unveiling.<\/p>\n

The Cosworth was far from alone in using four-wheel drive. The potential of a 4WD system had been shown as long ago as 1961, when Stirling Moss had won a non-championship race in an F1 car created by British tractor company Ferguson (which had then in 1966 contributed the first 4WD system for a road car, the Jensen FF), and it was an obvious solution when F1 engines became so powerful (with more than 400bhp) that cars started to struggle to put it all down.<\/p>\n

\"\"<\/p>\n

Lotus had seemed to prove the theory by almost winning the 1969 Indianapolis 500 with a gas-turbine 4WD car, and Matra\u2019s Jackie Stewart told us: \u201cThere isn\u2019t a tail slide and there isn\u2019t a lot of understeer; you can balance the car much better and therefore you can get out of corners quicker, and if you do that, you get down the straights quicker.\u201d<\/p>\n

Working on 4WD were Cosworth, BRM, Lotus, Matra, McLaren and Ferrari<\/a>. Most integrated Ferguson\u2019s proven system into existing chassis, but Northampton went its own way.<\/p>\n

We reported: \u201cDrive is taken from the engine, which is installed with the flywheel end forward, to a two-shaft gearbox with Hewland gears to give a wide choice of ratios.<\/p>\n

An extra gear, mounted on the end of the second motion shaft, takes the drive sideways to an angled bevel differential from which it is taken\u00a0to the front and rear final drives. The torque-split ratio is likely to be about 40:60 front to rear,\u00a0with further adjustment possible by altering front\u00a0and rear wheel diameters.<\/p>\n

\u201cThe rear drive passes under the right-hand cylinder bank of the engine and is\u00a0then taken sideways across the back of the engine by a\u00a0pair of spur wheels, suitably cased, to the rear differential.<\/p>\n

\u201cThe front driveshaft \u2013which, like the rear, is a solid shaft with Hooke joints \u2013 is taken through a guard tube directly to the front differential, side-step gears being unnecessary [here].<\/p>\n

\"\"<\/p>\n

\u201cTwo points in the layout of this drive stand out. One is that by arranging the fore-and-aft drive lines on the right-hand side of the car (Lotus and McLaren have theirs on the left), it has been possible to eliminate an idler wheel between the gearbox and the centre differential. This is necessary in the other designs to match the rotation of the engine and transmission.\u00a0<\/p>\n

The other is that it is believed that free differentials, without anti-spin mechanisms, are used in the front and rear final drives as well as\u00a0in the centre differential.\u201d Lotus entered its 4WD 63 at Zandvoort \u2013 but not with its lead driver Jochen Rindt at the wheel,\u00a0as he hated it so much in testing\u00a0that he refused to race it! Also in that race was Matra\u2019s 4WD MS80, later labelled by a driver simply as \u201cundrivable\u201d.<\/p>\n

And after racing his own team\u2019s 4WD M9A at Silverstone, Bruce McLaren apparently said it was like \u201csigning your name with someone pushing your hand along\u201d. Little wonder, then, that Cosworth\u2019s 4WD contender never graced a grid.<\/p>\n

\u201c4WD in F1 has been something of an anti-climax,\u201d we concluded in August 1969, and bar a single 1971 appearance of an experimental Lotus powered by a gas turbine,\u00a0it has never again been tried.<\/p>\n
