When the Renault RS01 first rolled onto the grid at the British GP in 1977, most of F1 paddock laughted.
The car looked unusual, sounded strange and under the engine cover was something almost no one in the sport believed could work, a tiny 1.5-litre turbocharged V6.
In an era when every front runner was powered by the trusty 3.0-litre engine, Renault gamble looked foolish.
The paddock mocked it and they gave the car a cruel nickname “the Yellow teapot” because it often broke down in a cloud of smoke.
But Renault had other plans, they planed a seed that would grow into one of the most dominant eras the sport had ever seen.
The Bold Experiment
Formula 1’s regulations allowed two types of engines:
- 3.0-litre naturally aspirated engines (what nearly everyone used), or
- 1.5-litre turbocharged engines (a loophole no one had dared to exploit).
They decided to bet everything on the second option, on paper, the theory was simple, a turbo could force more air into the cylinders, creating huge power from a much smaller engine.
In practice, though, no one had ever made a turbo survive the brutal demands of F1 racing.
The RS01’s debut in 1977, frankly, a disaster.
The car was overweight, overheating constantly and suffered from turbo lag so extreme that drivers compared it to an on-off switch.
Corner exists were sluggish, followed by a violent kick of power that made the car hard to control.
Reliability was not there, most races ended with the engine blowing.
Yet Renault insisted, they knew good days will come.
Faster where it mattered
Even in those early, painful years, there were glimpses of what the future held.
When the turbo started to work, the RS01 had staeggering straight line speed, the Cosworth powered cars could match Renault in corners thanks to their lighter, more balanced handling but once the Renault hit a long straight, the little 1.5-litre V6 engine pulled harder.
By 1978, the RS01 was producing around 520 bhp, slightly more than others on the grid 480-500 bhp.
It was enough to frighten rivals, not because Renault was winning, but because everyone could see what was coming if the French team ever solved its reliability problems.
The Breakthrough in 1979
Finally, two years of trial, error, it was paid off in 1979, Renault introduced the RS10, a lighter chassis and twin turbochargers that reduced lag and boosted power.
At their home GP, at Dijon, Jabouille delivered Rrenault’s first ever F1 victory, and the first turbocharged win in the history of the sport.
That same race is remembered even more for the battle of Arnoux vs Villeneuve, the fact that Renault was able to fight Ferrari showed that the revolution had truly begun.
How It Changed F1 Forever
So Renault forced the entire grid to rethink the future, Ferrari joined the turbo movement in 1981 with the 126C, and by 1983 every serious team had abandoned naturally aspirated engines.
Transformation was rapid, power levels jumped from around 500 bhp to more than 700 bhp in races and beyond 1,000 bhp in quali.
Straight line speed soared, drivers spoke of monstrous and acceleration, almost violent, with cars rocketing down the straights faster than anyone thought possible.
By the mid-1980s, the once-dominant Cosworth DFV was obsolete. The turbo era had arrived in full force, all because Renault had dared to look foolish in 1977.
So why we remember ‘The Yellow Teapot;
The RS01 never won a race. It broke down more often than it finished. But its influence on Formula 1 was enormous. What started as a laughingstock reshaped the sport, ushering in a decade where turbos reigned supreme until their eventual ban after the 1988 season.
Renault’s gamble was the ultimate example of innovation through persistence. They took the risk, endured the mockery, and in the end, changed Formula 1 forever.
