The NCC Autocross program uses a BMW-centric customized classing structure which pits your BMW or MINI against similar performance models in 3 levels of trim: Showroom, Tuner, and Modified. There is also a simple classing structure for non-BMW competitors. You can check out the full details at www.nccautocross.com.

Non-BMW Classing

There are five non-BMW classes, X1, X2, X3, X4 and X5. Class X5 is reserved for all non-BMWs with R-Compound tires (defined as having a treadwear rating less than 200). The remaining classes are based on vehicle displacement and modified according to the rules below.

X1 = 5.0 Liters and up and all electric vehicles (Non-BMW 1)

X2 = 3.7 - 4.9 Liters (Non-BMW 2)

X3 = 2.6 - 3.6 Liters (Non-BMW 3)

X4 = 2.5 Liters or less (Non-BMW 4)

X5 = R-Compound Tire Cars Only (no matter engine size) (Non-BMW 5)

After the base group is determined from the above table, move up one group as follows:

Increase one group if engine uses forced induction (either factory or aftermarket).
Increase one group if engine is rotary.

X5 is specifically reserved for cars with competition tires no matter what engine the car is equipped with.

Examples:

A 2018 Mazda Miata (2.0) would be in X4. However, a 2018 Fiat 124 Spyder (1.4) which is essentially the same car would be in X3 due to the turbocharger.
A 2010 Subaru WRX STI (2.5L) moves up from X4 to X3 because it has forced induction. Even factory forced induction, such as in this case, causes a car to move up 1 Group.
A 2010 Chevy Camaro V6 (3.6) would be in X3. A V8 (6.2) would be in X1 no matter the trim (LT, LS, SS, ZL1, etc.). The same car with R-Compound tires would complete in X5 no matter the engine size.
A 2008 Mazda RX-8 (1.3L) would be in X4, but is an X3 car because of its rotary engine. If the same RX-8 competes with R-Compound tires, it is in X5.
