Racing Master Extreme Tier List (Season 4)
With the arrival of the Bugatti Centodieci, there are now a total of 22 Extreme-class cars available in Racing Master Season 4. Below is the complete tier list for each rarity, ranked based on average best lap times.
Legendary

S Tier


A Tier

C Tier

The Extreme category in Racing Master Season 4 continues to be dominated by top-tier powerhouses like the Pagani Huayra, Bugatti Chiron, Koenigsegg Agera, and the newly added Bugatti Centodieci.
Prioritize upgrading SS and S-tier cars first before focusing on mid and lower-tier Legendary cars. These top-tier vehicles are the ones that can boost your rank more effectively and much faster.

C Tier
Taycan, Exige, and Corvette C8 stand as the top-tier Rare Extreme cars in Season 4. With at least ECU 3, these top-tier Rare cars can even go head-to-head with the current top-tier Legendary cars. They are the most worthwhile Rare Extreme cars to upgrade.
Normal
SS Tier
S Tier
A Tier
B Tier
C Tier

There is only one Normal rarity car in the Extreme category, and it's far from impressive. Even with ECU 5 and a full 25/25 upgrade, the E-Tron struggles to compete against mid-tier Legendary or top-tier Rare cars.
Note that this tier list is based on the average best lap times, as well as the overall speed and control of the cars. This does not mean that SS-Tier cars will always win races. Ultimately, the results depend on your mastery of the cars and their upgrade levels.
Now that you know which cars to prioritize, make sure to fine-tune them using the best Extreme tuning setups to fully maximize their performance.
