From 2002 to 2015, Top Gear was hosted by the famous trinity: James May, Jeremy Clarkson and Richard Hammond. We all loved watching them go on trips, test cars and just have fun.

However, Clarkson had a fall out with the BBC and left the show. In a year, he, Hammond and May had reunited for The Grand Tour. Here are 10 cool facts we didn't know about The Grand Tour (and 5 things the hosts don't want us to know).

One of the coolest parts of the Grand Tour is the pack of flying jets. These are Aero L-39C Albatrosses operated by the Breitling Jet Team. The show looks impressive, but these jets cause lots of problems. Studio members say that many segments have to be reshot because of the Albatrosses.

Game of Thrones fans may have noticed that in episode 5 the hosts stopped by the set of GoT.

There are only 22 Maserati Bi-Turbos registered in the UK and only 6 of them are 430s. One of them is now in bits at the bottom of the English Channel. One of the seats from that Maserati in episode 11 was saved. It sits in the Grand Tour office as a smelly trophy.

Just like any other TV show, the Grand Tour has to make things seem faster than they really are. One striking example is a test track drive. You'd think it takes a few hours. However, it takes the whole day to film a race. Races should be shot more than once for the right angle.

The weather can often mess things up. In 2016, the trio had to film a Christmas special. They thought it'd be great to film in Finland and have a snowy background with pretty winter decorations. However, Finland was in a heatwave. The hosts had to wait for a winter storm.
