All of the 2015 F1 steering wheels

Most Formula One steering wheels were given a major overhaul last year with the introduction of bigger LCD screens that display hundreds of data and suit better the complex technology of the new hybrid-powered cars. 

Following the FIA’s clampdown on radio conversations, several teams that still had a small screen (Red Bull, Williams, and Lotus) decided to switch to the larger PCU-8D model for 2015. This forced them to redesign their steering wheels in order to accommodate this new device

While some settings feature on all steering wheels, others are specific to each team as you are about to find out.
