Amazon Prime apparently spent $380m signing up the trio, making it Amazon's biggest single investment in original content to date. With 36 episodes in the pipeline, each individual episode will have a reported $10m budget.
In contrast, the budget for Top Gear was just over $2.3m, including the presenter costs.
Founder and Amazon CEO Jeff Bezos admitted the deal had been "very, very, very expensive".
The announcement of the new show ended months of speculation about the trio's future after numerous broadcasters and online streaming services, including Netflix, had tried to snare the presenters.
All three, as well as Wilman, left the BBC in March following the incident at a hotel in North Yorkshire, which took place after a day of filming. According to an internal BBC probe, Clarkson attacked a producer, Oisin Tymon.
Wilman, widely regarded as the brains behind Top Gear, revealed it was the budget, plus autonomy over the show, which secured the team.
Because Amazon is a US-owned internet brand, the deal gets round a ban on Clarkson doing a car show with any UK broadcaster until 2017.
Amazon Prime is one of the new rash of international companies offering access to TV shows and movies online for a monthly subscription.
