For my company, Ursula AG, Here’s a typical layout for naming models for the vehicles from the brand:
Models
Most models are named like F* where * denotes a number, often odd numbers (eg. F3, F5, F7). For the numbers, the larger the number, the larger the model.
There are some exceptions, ofc.
If it’s an SUV then FX(number) is used rather than F(number).
If it’s an van then FP(number) is used instead.
Most sports cars uses the G(number) layout. With the exception of the R1/V7 GTs ofc.
EVs will start from the eV prefix.
Trim levels
Often it will be a 3 digit number like 200/300/400 all the way up to 800 in most cases. Most of the time it’s just denoting the level of trim, engines are not used on most cases.
Some suffixes were used for some cases:
d: diesel
e: hybrid
ed: diesel-hybrid
X: all-wheel drive
S: sport model, similar to Audi’s S models
W: luxury model
RS/RS-R: high-performance models, with RS as a lower-tier model and RS-R for the higher end ones. Kinda like Audi’s S/RS models, except both are on RS-territory with the RS-R models has higher performance.
WX: high-end luxury models, not often used in most vehicles. Think Mercedes-Maybach for this.
Engines
The usual engine format for all vehicles are like this:
XX-YY/Z-A
XX - Engine code, usually 2 alphabets.
YY - Engine size,
Z - Engine cylinders
A - Variant
