The Grand Tour's first series achieved estimated viewing figures of 2.3 million in December, research has revealed.
Jeremy Clarkson, Richard Hammond and James May hosted the series, which streamed exclusively on Amazon Prime. The figures compare to 5.8 million who watched the trio's final episode of Top Gear on the BBC, and 8m who tuned in at that show's peak.
However, the numbers are not as bad as they seem. The Grand Tour has been a huge success for Amazon's streaming service, becoming its most popular show and attracting new subscribers.
After Clarkson's contract with the BBC ran out following controversy about a 'fracas' with a producer, Amazon stepped in with a massive budget to tempt all three presenters to make a show for its streaming service.
The numbers come from a survey of 2,500 viewers of streamed content by market analysts GfK, which also questioned viewers about their opinions on what they watched.
It found that viewer reception to the new show was good, with 55 per cent saying it was better than Top Gear, while 45 per cent said it was better than they were expecting.
Christopher Smith, senior research executive in GfK's brand and customer research division, said: "Our analysis proves that the high production costs for The Grand Tour are paying off, with viewers of the show agreeing that Amazon's investment has been worth it."
