Top Formula 1 drivers have reacted coolly to the unveiling of the sport's new logo.
Although the full F1 rebranding will not be launched until the start of next season, the world got a peek at the new logo on the podium of the 2017 finale in Abu Dhabi.
"We wanted to present it now in order to help our partners look into how they will use it," F1 commercial boss Sean Bratches is quoted as saying by La Gazzetta dello Sport.
Sebastian Vettel, referring to the iconic 'flying 1' logo that was introduced in the Bernie Ecclestone era in 1993, said: "I liked the old one better."
Liberty Media's new F1 trademark is a stylised F and 1, similar to the red ESPN logo.
"It feels like the new owners want to prove themselves by abandoning what was done before," Igor Yermilin, a Russian motor racing official, told Sportbox.
"But the new logo is incomprehensible, uninteresting, cheap and primitive."
Abu Dhabi winner Valtteri Bottas added: "What was wrong with the old one?"
World champion Lewis Hamilton said: "I think the one we had already was iconic. Just imagine Ferrari or Mercedes changing their logos."
F1 commercial boss Sean Bratches explains: "Many people never realised that there was an invisible 1 between the F and the 1 in the old logo. The new logo is clearer.
"It was also difficult to embroider the impression of speed in the old logo on shirts, etc.
"In the digital era, big brands like Starbucks and Coca-Cola have simplified their logos for clarity, and that's the case for us as well."
As for the criticism, Bratches said: "Every time a brand is changed, and especially a brand that arouses so much passion, you have to expect these reactions.
"It's normal that people do not like change, but I think that's good because it shows that people care about the brand."
FIA president Jean Todt said that the sport's governing body approves of the new logo.
"It's up to the rights holders to introduce a new logo if they want to," he said in Abu Dhabi.
"People should be positive about change. The people at Liberty are very talented and have proven their qualities in other sports. I trust their judgement."
The 'flying 1' logo had been in place since 1987.
