Formula One star David Coulthard and German racing driver Sabine Schmitz could be joining Top Gear's presenting line-up, it has been reported.
Motoring journalist Chris Harris will also be joining the show, according to The Sun.
On Tuesday it was revealed that the show's executive producer, Lisa Clark, was leaving the show after five months.
Clark, who had previously worked with Top Gear host Chris Evans on Don't Forget Your Toothbrush, said in a statement she was "moving on to new projects".
She added: "I'd like to wish production all the very best with the show."
The BBC issued a statement thanking Clark for her "incredible work for the last five months readying new Top Gear for its busy filming schedule in 2016 and planned return in May".
So far Evans has been tight-lipped about the format of the show.
Appearing as a guest on BBC One's Saturday Kitchen recently, he did reveal the first episode would air on Sunday May 8.
The BBC said it would not comment on any speculation regarding the line-up for the new show.
Why are you making commenting on The Herald only available to subscribers?
It should have been a safe space for informed debate, somewhere for readers to discuss issues around the biggest stories of the day, but all too often the below the line comments on most websites have become bogged down by off-topic discussions and abuse.
heraldscotland.com is tackling this problem by allowing only subscribers to comment.
We are doing this to improve the experience for our loyal readers and we believe it will reduce the ability of trolls and troublemakers, who occasionally find their way onto our site, to abuse our journalists and readers. We also hope it will help the comments section fulfil its promise as a part of Scotland's conversation with itself.
We are lucky at The Herald. We are read by an informed, educated readership who can add their knowledge and insights to our stories.
That is invaluable.
We are making the subscriber-only change to support our valued readers, who tell us they don't want the site cluttered up with irrelevant comments, untruths and abuse.
In the past, the journalist’s job was to collect and distribute information to the audience. Technology means that readers can shape a discussion. We look forward to hearing from you on heraldscotland.com
