Mario Kart 8 Deluxe
London Loop returns in Mario Kart 8 Deluxe as part of the third wave of the Booster Course Pass. It is the first course of the Rock Cup. The course has received significant visual upgrades, and is now set in cloudy weather. Various details on the top of Big Ben have been removed, such as windows and spires. The now moves, unlike its Tour counterpart. The various Barrels and Crates on the course have been removed. The minimap is rotated 90 degrees clockwise and features multiple paths that are unused in Mario Kart Tour at the time of the course's addition in Mario Kart 8 Deluxe, such as one to the right of Leadenhall Market, and the one going beneath the Admiralty Arch. This makes London Loop the second/third Tour city course to include roads that were unused at the time of their appearance in the Booster Course Pass, after Sydney Sprint and alongside Berlin Byways.

The first lap is based on the first London Loop route. Racers begin on, facing Big Ben. An arrow field immediately directs them to turn right and drive through. Unlike in Tour, racers can perform tricks off of the center of the roundabout. They can also drive the long way around the roundabout, though there is no benefit to doing so. Either way, players then drive around the front of and come to. They can still drive through it, but there is now also the option to drive on a straighter path to its right unused in any Tour route. From there, they drive through a right curve past a Chain Chomp chained outside the Tower of London, across, and back to the starting line taking the route past.

The second lap is based on London Loop 2. As such, racers go straight and enter. There is another Chain Chomp there, and an additional one chained near the left side of the gate. After leaving the park, an arrow field directs racers left through a long road, with exits with a ramp pointed toward the front door of the Bush House. Players then drive across before taking two right turns to pass the starting line again.

The third lap is a combination of London Loop 2 again and London Loop 3R, making this the third Mario Kart Tour city course to feature a section based on an R variant from its original appearance, after and. Players once again drive through St. James's Park. However, the Chain Chomp has broken loose and is now roaming around, occasionally crossing onto the road. The Chain Chomp outside the park's gate has also freed itself and gone through the to circle the Charing Cross. Racers follow it and drive straight toward the (where an Unchained Chomp is swimming, of no consequence to the player). Players drive along the Thames and under the Waterloo Bridge before taking the right turn near the Tower of London again, whose Chain Chomp has also broken loose. They drive over the Tower Bridge again, turn right to drive on the other side of the Thames, and then head for the finish line to end the race.

This course being positioned in the Rock Cup may be a reference to the course's music, which is based on British rock music from the 1960s and 1970s. It is also one of two courses in the third wave to utilize rock music for its theme, alongside. Both of these courses are in the Rock Cup. Also, during the beginning of this course's music, a second guitar plays a few notes, panned to the left. This guitar is absent in all subsequent loops of the song.

London Loop is one of three Mario Kart Tour courses in the wave overall, alongside and Merry Mountain.

Trivia

 * Unlike other courses using arrow fields in the Booster Course Pass aside from, London Loop can be driven in reverse from the beginning without Lakitu picking up the player. However, this bizarrely loads the third lap layout with the unchained Chain Chomps, meaning that if the player turns back around and resumes following the course normally, the Chain Chomps will rechain themselves, only to be unchained again once Lap 3 is triggered properly.
