Top Gear is the most popular car show of all time, with countless episodes that are both entertaining and educational, promoting the latest cars, discussing news, and bringing in celebrity guests. The show really does have it all.

The highlight of the show each week is always the challenge that the hosts end up having, whether it be finding the cheapest car possible to do the furthest distance or a simple race across the country, they are always fantastic.

Of course, as with any television show, Top Gear has its great episodes and its weaker episodes, and within this article, we will be taking a look at the five highest and five lowest-rated episodes, according to IMDb.

10 Worst: #23.4 (2016)

Kickstarting the list is season 23 (get used to that), with the fourth episode of the season which earned a 2.3 rating from IMDb as the episode clearly did not go down well, despite BBC throwing plenty at it.

Within the episode, the hosts buy cheap second-hand cars and set off for Venice with the aim being to prove that road travel is more luxurious than taking the train, which seems like a fairly fun challenge but it didn't transpire that way.

As well as that, Rory Reid went to New York and tried out the Tesla Model X in what should have been a solid episode of the show, but things just never clicked.

9 Greatest: Africa Special, Part 2 (2013)

Kickstarting the greatest episode portion of this list we have the Africa Special, Part 2, which earned a stellar 9.2 rating on IMDb and it was certainly deserving of that as this is a hilarious episode of Top Gear.

Within this episode, Jeremy Clarkson, Richard Hammond, and James May continue their African journey and things do not get easier as their estate cars are pushed to the brink by all manner of problems.

As you can see by the image above, the cars are rafted across the water at one stage, which leads to some brilliant arguments between the presenters on an episode packed with challenges that they must overcome.

8 Worst: #23.2 (2016)

Once again, Season 23 is brought into question by IMDb, who gave the second episode of the season a low rating of 2.3 out of 10, pretty much confirming that it isn't worth your time to dig out and watch.

During this episode, the hosts take various music talents such as Seasick Steve and Tinie Tempah on a wild SUV test in South Africa, but that fails to capture the magic that past Top Gear overseas trips have brought.

Even bringing F1 legend, Jenson Button onto the show, a legitimate top driver, didn't save this episode from being complained about by fans and critics.

7 Greatest: Burma Special: Part 2 (2014)

Another popular 'Part 2' in Top Gear history comes from the Burma Special, with the second part of the journey being one of the highest-rated episodes in Top Gear history on IMDb, with a score of 9.2.

The presenters were continuing their journey through the Shan regions of Burma in this episode in their old trucks, but if that wasn't funny enough, what the hosts didn't realise is there was another challenge waiting for them.

When they arrived at the River Kwai they were informed about the fact they needed to then build a bridge over it, which is why they had been in the big trucks in the first place.

6 Worst: #23.5 (2016)

Another episode from season 23 that failed to connect with audiences critics alike came from the fifth episode, with IMDb giving it a rating of just 2.2 out of a possible 10, despite having some fantastic cars on display.

Chris Harris tried out the new BMW M2, while Matt LeBlanc traveled to Ireland to see the latest car from Rolls-Royce and even Paul Hollywood stopped by to discuss his latest cookbook.

However, the main part of the show saw Rory Reid go back in time in a journey against the clock, recreating the journey of Jaguar's former test driver, Norman Dewis as Reid tries to get the Jaguar F-Type SVR Convertible to the Geneva Motor Show on time.

5 Greatest: Bolivia Special (2009)

Another one of Top Gear's highest-rated episodes (9.4 on IMDb) and it is another one of the special episodes, this time with the boys travelling to Bolivia where they commence a 1000-mile journey from the Amazon Rainforest to the Pacific Ocean.

Of course, there is always a twist with the show and that twist came in the fact they had to buy cars that are four-wheel drive and had to be found in the Bolivian second-hand classifieds, just to make it even trickier.

The episode featured some hilarious moments with the best being when they had to get their cars onto a boat, slowly using the wooden planks without submerging themselves into the water.

4 Worst: Episode #23.6 (2016)

Another incredibly poor episode of Top Gear saw Matt LeBlanc get his hands on the brand new Porsche 911 R, while Chris Evans drove the MGB Roadster, discovering the old-fashioned vehicle.

Rory Reid drivers a right-hand-drive Ford Mustang and Greg Davies drives around the track trying to set a top time, but that all of that didn't stop IMDb giving it a low rating of 2.1 out of a possible 10.

It is clear that IMDb did not find the 23rd season of Top Gear to be a good one, with many of the worst-rated episodes coming from that season, with the new hosts not quite clicking the way BBC had hoped.

3 Greatest: Episode #22.8 (2015)

With a rating of 9.4 on IMDb, the #22.8 episode of Top Gear is rated the second-best of the show in history with the trio having to acquire traditional classic convertibles for their adventure.

As well as that the hosts are challenged to each buy a high-mileage but also a low-quality SUV costing no more than £250. The challenges involved indoor ski slopes, caravans, and a whole lot of mud to see which would perform the best.

Interestingly, this was also the last episode of Top Gear that featured Jeremy Clarkson and was the first and last time the show was hosted by James May and Richard Hammond only.

2 Worst: #23.1 (2018)

So here we are, the official worst-rated episode in Top Gear history (to date), with a dreadful IMDb score of 2.1 and it was actually the first episode with the change of hosts following the departure of Jeremy Clarkson, James May, and Richard Hammond.

Whether it was because of that change in hosts or simply that the new format didn't click, this is the worst-rated episode in Top Gear history with Chris Evans and Matt LeBlanc starting a road trip to...Blackpool.

The two men spend their time focusing on UK vs USA challenges, and the show certainly pulled out all the stops with the guests of Jesse Eisenberg and Gordon Ramsey, but that still didn't save the episode from being a disaster.

1 Greatest: Vietnam Special (2008)

The Vietnam Special episode of Top Gear from 2008 is currently considered to be the greatest in the history of the show according to IMDb, with a rating of 9.5, the episode almost earned a perfect score.

Obviously, the hosts travel to Vietnam for this episode where they commence an epic road trip across the country which leads to some incredible comedic moments dealing with the environment and the entire situation.

Each man is given 15 million dong which is around $1000 to spend on some wheels as they must then go about things on their own in what is an incredibly entertaining episode of the show.
