When asked if he was surprised other teams had not faced similar investigations, he said: "Yes. Because I think there have been so many issues with these sensors.
"I don't think any of them have been working 100 per cent reliably through the weekend. Even in the race, quite a few have acted incorrectly."
FIA AWARE OF CALIBRATION ISSUES
The FIA has been aware of accuracy issues in the fuel-flow sensors, which are provided by the British company Gill Sensors.
AUTOSPORT understands that calibration problems came to light during pre-season testing regarding their accuracy.
In promotional material on its own website, Gill Sensors claims that 52 per cent of its meters are with a 0.1 per cent accuracy reading, with 92 per cent within 0.25 per cent.
Teams and the FIA have found that some of the sensors are wildly out, however, which means they are unsuitable for use.
But with this characteristic having come to light during pre-season, the FIA is confident that it and the teams have learned how to achieve good accuracy.
When asked earlier in the Australian GP weekend about the situation, F1 race director Charlie Whiting said: "It is very apparent right from the beginning whether or not an individual sensor is going to work.
"It is either very, very good or a long way out, so you can identify whether or not that meter should be used.
"We monitor them all the way through the race and if we see a fault we have a fallback solution."
Max Verstappen’s star quality in Formula 1 is clear. Now equipped with a Red Bull car that is, right now, the world title favourite and the experience to support his talent, could 2021 be the Dutchman’s year to topple the dominant force of Lewis Hamilton and Mercedes?
For many, many years Formula 1 has strived to do and to be better on all fronts. With close competition, a growing fanbase, a stable political landscape and rules in place to encourage sustainability, 2021 is on course to provide an unexpected peak
The longer Red Bull can maintain a performance edge over Mercedes, the better the odds will be in the team’s favour against the defending world champions. But as the Bahrain Grand Prix showed, many more factors will be critical in the outcome of the 2021 Formula 1 World Championship
Nikita Mazepin’s Formula 1 debut at the Bahrain Grand Prix lasted mere corners before he wiped himself out in a shunt, but his financial backing affords him a full season. Back in 1993 though, Marco Apicella was an F1 driver for just 800m before a first corner fracas ended his career. Here’s the story of his very short time at motorsport’s pinnacle
Mercedes and Lewis Hamilton took victory at the Bahrain Grand Prix despite, for a change, not having the quickest car. But any hopes of developing its W12 to surpass Red Bull's RB16B in terms of outright speed could not have come at a worse time.
Kimi Raikkonen’s emergence as a Formula 1 star in his rookie campaign remains one of the legendary storylines from 2001, but his exploits had an unwanted impact on his Sauber team-mate’s own prospects. Twenty years on from his first F1 podium at the Brazilian GP, here’s how Nick Heidfeld’s career was chilled by the Iceman
