It was back in February when Lewis Hamilton raised concerns about the sounds emitted from Formula One cars.
"I've said time and time again that I think it's terrible,” Hamilton said when asked about the lack of engine noise, per Eurosport. “Most people are like 'oh, it's not that bad'. But my opinion is that I think it is.
"When I first went to a grand prix at Spa in 1996, got into the paddock and Michael [Schumacher] came past in the V10 [Ferrari] and it literally rumbled my ribcage.
"I was hooked even more than I was when I'd watched it on TV. It was like a fighter jet - I was like 'what the hell?'
"It's not the only thing the fans love, but it's an addition to smell, to the roar of awesomeness that Formula 1 is.
"Take that away and, jeez, it's just sad to see the cars come by now, sound-wise."
Hamilton, who secured his fourth world title last Sunday, will be pleased to know that the next generation of Formula 1 engines are in a conceptual phase - and there’s a desire for them to be louder and offer more power.
Per The Drive, who quote Motorsport Magazine, F1 engines at the moment rarely reach 13,000 RPM.
But with an increased fuel flow limit, engines in the future should rev to the mid-14,000 range, where they could make around 1,200 horsepower.
How F1 cars could sound in 2021
A YouTube video produced a show what F1 cars could sound like in 2021 makes for interesting viewing.
The video features clips sourced from the 2017 season, with on-board footage from pre-season testing in Barcelona and the United States Grand Prix weekend.
Have you ever heard anything like that Force India?!
It’s just a simulation, of course, and more tests will be carried out in the future.
Ferrari aren't pleased with proposed changes
Formula One’s new owners, Liberty Media, are planning new changes to the sport that don’t sit entirely well with Ferrari.
Their chairman, Sergio Marchionne, said Ferrari could quit F1 if it is taken in a completely new direction.
"It (Formula One) has been part of our DNA since the day we were born," Marchionne said, per the Independent.
"But if we change the sandbox to the point where it becomes an unrecognisable sandbox, I don't want to play anymore."
