Here are the main differences between the Moza R12 V1 and the R12 V2 with regard to your request:

- Force feedback accuracy (FFB): The R12 V2 uses a high-power 12Nm servo motor with a low-cog offset pole design and Moza's NexGen 4.0 algorithm, which improves FFB accuracy and smoothness compared to the V1 version.

- Track feel and FFB power: The R12 V2 delivers a stable and realistic torque of 12 Nm with a peak power of 216 W, offering a more powerful and immersive force feedback, thanks in particular to improved vibration and rumble effects, which improve track feel compared with the V1.

- Compatibility with Moza steering wheels: The R12 V2 extends compatibility to the entire current range of Moza steering wheels, with the exception of certain older models such as the RS V1, GS V1 and CS V1. All other steering wheels, including updated versions, are compatible with the V2. This compatibility is broader than that of the V1.

- Other differences: The R12 V2 is built from aerospace-grade aluminium alloy with an active cooling system and full software integration, improving reliability and durability. The design is very similar to the V1, with a shorter, slimmer steering column, and slightly more weight due to the more powerful engine.

In short, the R12 V2 offers greater force feedback accuracy and power, a more immersive feel, greater compatibility with current Moza steering wheels, and improved construction, beyond the price difference.
