1959 Cooper T51: Tiny British Team That Humiliated Ferrari and Changed F1 Forever

Hinzugefügt: 2026-05-11

[00:00:00]In 1959, a car showed up to the Formula 1 World Championship that looked like it had been built in someone's garage. That is because it had the Kooper to 51 cost less than £1,000, had a four cylinder engine where every rival had a six or more, and carried that engine bolted behind the driver at a time when every serious team in the world put theirs in the front. The establishment laughed at it. Then it won everything. [music] Number 10. The Kooper car company did not start with some grand engineering vision. It started with a motorcycle engine and a problem. Charles Kooper was a racing mechanic between the wars and his son John wanted to go racing. They could not afford a proper car. So in 1946 they welded two front ends of a Fiat chassis together and dropped a 500cc motorcycle engine behind the driver. The engine went in the back for one practical [music] reason. It was chain driven and chain drive works best when the engine sits near the rear wheels. Nobody at Kooper was running aerodynamic calculations or [music] theorizing about weight distribution. It was just a father and a son making do with what they had in a small workshop in Serbetton Surrey.

[00:01:25]That car raced in hill climbs through 1946.

[00:01:29]And when the first ever 500cc circuit race in Britain was held at Granddon Lodge airfield in 1947, Eric Brandon won it in a Kooper. Orders started flooding in. Kooper kept building rear engineed cars after that because it was cheap and it kept winning.

[00:01:50]Number nine. While Cooper was quietly climbing through the lower racing formula, Enzo Ferrari watched from Marinelo with open contempt. He called Kooper and the other small British teams garages, garage owners, assemblers. The full Italian phrase was garajist [music] assemblator and it was meant to sting.

[00:02:13]In Ferrari's world, a real racing team designed and manufactured its own [music] engines, its own gear boxes, its own everything. These little British operations were buying Coventry Climax engines off the shelf, bolting them into lightweight frames they had welded together in a shed, and showing up to race against teams with decades of tradition and factory infrastructure behind them.

[00:02:35]Ferrari saw it as an insult to proper engineering. What he did not see was that these so-called grease monkeys were about to make his entire approach to car design obsolete.

[00:02:47]Number eight, the Kooper T-51 was not just cheaper than a Ferrari. It was almost [music] absurdly cheap. When the Yman Credit Racing team purchased three T-51 chassis in October of 1959, they paid £980,5 shillings [music] and£10 each. That is under £1,000 for a rolling Formula 1 chassis capable of winning the World Championship. [music] Kooper was running a business, not a vanity project. By 1958, 19 Koopers of various types made up more than half the grid at the International Trophy Race at Silverstone. They were the largest manufacturer of racing cars in the post-war world. And they achieved that status by building cars that club racers and privateeer teams [music] could actually afford to buy and campaign without a factory budget behind them. In total, 38 different drivers would race T 51 chassis in Grand Prix events over the car's lifetime.

[00:03:46]Number seven. Under the rear bodywork sat a 2 and a half liter 4 cylinder engine [music] built by Coventry Climax producing 240 horsepower at 6,750 revolutions per minute. Ferrari's [music] Dynino 246 had a V6 producing closer to 290 horsepower. On paper, the Kooper should have been left behind on every straight. The difference was what the rear engine layout did [music] for the rest of the car. With the engine behind the driver instead of in front, the Kooper had a dramatically smaller frontal [music] area, which meant less aerodynamic drag at speed. It eliminated the need for a long propeller shaft running under the cockpit, saving [music] weight and complexity. The fuel tank sat on either side of the cockpit rather than at the rear, so the car handled consistently whether the tanks were full or nearly empty. a crucial advantage during races that could last up to three hours. Gordon Murray, the designer behind some of the greatest racing cars ever built at Brabom and McLaren, later called the Kooper T-51 the single most significant change in Grand Prix car design, [music] praising its fundamental rethinking of packaging, weight distribution, and frontal area.

[00:05:04]What the Kooper lost in raw horsepower on the straits, it clawed back in every braking zone and every change of direction.

[00:05:12]Number [music] six, the chassis itself broke almost every rule in the structural engineering textbook. Owen Maddock designed a space frame where nearly every tube was curved [music] rather than straight. Any structural engineer will tell you that curved tubes are weaker than straight ones underload.

[00:05:29][music] And at the time, plenty of engineers said exactly that. Maddock did it anyway. The overall geometry of the frame compensated [music] for the individual weakness of each member, and the result was a chassis that was light, reasonably [music] rigid, and fast to manufacture. Revs Institute preserves one of the original T-51 chassis [music] and describes the Koopers as having been likened to blacksmiths. The engineers who came after them, people like Colin Chapman at Lotus, took the brilliant idea and refined it. Cooper fired the first shot and others would finish the revolution, but that crude curved tube frame won the championship first.

[00:06:08][music] Number five, finding a gearbox for a rearengineed Formula 1 car in 1959 was a genuine engineering headache. So few rearengineed production cars existed at that time [music] that there was almost nothing available to purchase off the shelf.

[00:06:27]Kooper's [snorts] solution was beautifully crude. They took a gearbox from a Citroen traction avant road car, turned it around backwards, and bolted it to the climax engine. The works team used these modified Citroen units fitted with close ratio gears manufactured by a French firm called Air. These gearboxes took a savage pounding from the 2 and a half liter engine, twisting them under load.

[00:06:51]And after every single race, the entire internals had to be stripped and replaced. Gears, selector forks, dog rings, all of it. Most of the oil would leak out of the breather during the race. [music] Anyway, Rob Walker's private team tried a different approach, sourcing bespoke gear boxes from Italian specialist Valerio Colotti. Those turned out to be even more fragile than the Citroen units. The whole gearbox shortage was so severe that it eventually created a market opportunity for a company called Huland, which went on to dominate racing gearbox supply for decades. But in 1959, nobody had that luxury. Kooper was racing with road car parts held together by hope and a weekend rebuild schedule.

At the 1958 Argentine Grand Prix, Moss drove a smaller Koopa T43 with a Climax engine bored out to just under 2 L against the full factory Ferrari team running 2.4 L V6s.

[00:08:29]He was outgunned on horsepower by a significant margin.

[00:08:34]Moss ran the entire race without making a [music] single pit stop, nursing a set of tires so worn that the canvas was showing on both rear wheels by the finish and won by less than 3 seconds.

[00:08:47]It was the first victory for a rear engine car in World Championship history.

[00:08:54]The warning signs were there for anyone [music] paying attention. Ferrari chose not to pay attention. Number three, Jack Brabbom was not just a fast driver. He was a trained mechanical engineer who had spent years working at the Kooper factory in Surrey. He originally started showing up to scrge spare parts and gradually became part of the operation.

[00:09:18]As John Cooper later put it, he did not so much start working for them as working with them. [music] He just began coming in more often and they got used to having him around. His most critical contribution beyond the cockpit was redesigning the T-51 gearboxes to make [music] them dramatically more reliable.

[00:09:37]Brabom corresponded with his Australian engineer friend Ron Terranac on the modifications and the improved units [music] went exclusively into the works Kooper cars.

[00:09:48]Every other team running a T-51, and there were more than 10 of them, were stuck with the standard fragile gearboxes that ate themselves after every race. Brabom's son David later explained that it was Jack's engineering ability more than anything else that won him the 1959 championship.

[00:10:06]Number two, the final race of 1959 was the United States Grand Prix at Sebring, Florida, held on a bumpy former bomber base surrounded by Orange Groves. Brabom arrived leading the championship with 31 points. Sterling Moss had 25 and a half and Ferrari's Tony Brooks sat on 23. All three could still win the title. Moss took pole position and sprinted into a 10-second lead within five laps, but his gearbox, one of the standard [music] unreliable Kooper units, failed on lap five. Brooks was rammed from behind by his own Ferrari teammate, Wolf Gang [music] von Trips at the first corner, forcing an unnecessary pit stop that ruined his race. Brabom led from there, nursing his car through the Florida heat for over two hours. Then on the final lap, 400 yds from the finish line, the climax engine sputtered and died.

[00:11:02]Out of fuel, Brabom climbed out of the cockpit, grabbed the car, and pushed.

[00:11:08]The rules required him to finish without outside assistance. [music] So he shoved the Kooper uphill toward the checkered flag while Bruce McLaren, Morris Trenting, and Tony Brooks all swept past him. He crossed the line in fourth place, collapsed from dehydration and exhaustion and needed a full [music] 15 minutes lying on the ground before he could even stand. Fourth was enough. He was the first Australian world champion and the Kooper T-51 was the first rear engineed car to win both the drivers and constructor's championships.

[00:11:43]McLaren at 22 years old became the youngest Grand Prix winner in history that day. He later said Brabbom had gifted him the win by holding back earlier in the race and letting the young Kiwi match his pace. Number one, the Kooper T-51 did not just win a championship.

[00:12:01]It killed an entire philosophy of car design practically overnight. In 1959, most of the grid was still front engineed. By 1960, Brabom won five consecutive races in the updated Koopa T-53, and Colin Chapman's Lotus 18, directly inspired by Kooper's layout, was winning races as well. By 1961, every single car on the Formula 1 grid had its engine behind the driver.

[00:12:28]Ferrari, the team that had mocked Cooper as garage owners, was the last to make the switch, building the rear engineed 156 for the 1961 season. After 1960, no front engine car ever won a World Championship race again. Every Formula 1 car, every Indie car, every Lemon prototype built in the decades since follows the layout that Charles and John Cooper stumbled into because they could not afford to put a motorcycle engine in the front of a Fiat [music] chassis.

[00:12:56]The most important car in racing history was designed by accident. Built on a shoestring [music] and driven to glory by a man who had to push it across the finish line.
