A new batch of cars has arrived in Racing Master 26S1 SEA, and one of the highlights is the Koenigsegg One:1 in the Extreme category. To help you decide which high-performance machine is worth your time and resources, here’s a tier list ranking all Extreme cars from best to worst.
*This page will be continuously updated with every season update.
Racing Master Extreme Tier List (26S1)
With the arrival of Koenigsegg One:1, there are now a total of 28 Extreme-class cars available in Racing Master 26S1. Below is the complete tier list for each rarity, ranked based on average best lap times.
Legendary
SS Tier







S Tier







A Tier



B Tier


C Tier

This season introduces the second Koenigsegg in the game, the Koenigsegg One:1. As expected from the brand, the One:1 sits at the very top of the tier, effectively replacing the Agera RS in that position.
The best Extreme cars are still LaFerrari, Centodieci, Chiron, P1, and Huayra, but with the right handling and the same ECU setup, the One:1 can go head-to-head with them and even come out on top.
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.
Rare
SS Tier


S Tier

A Tier

B Tier



C Tier
Taycan, Exige, and Corvette C8 stand as the top-tier Rare Extreme cars. 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

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.
