THE previous-generation (E90 series) BMW M3 seemingly provided the proof that hydraulic steering is king when it comes to letting road feel flow up the steering column. The M3 (and the 335i) stuck with the old technology until 2013, even though much of the 3 Series line-up went EPS in 2004. It was the same in the second-gen Renaultsport Clio, which retained hydraulic steering when the regular versions adopted EPS in 2001. However, this was not because hydraulic steering was inherently better, just that engineers hadn’t optimised EPS for hi-po feedback levels yet.
The current M3 and M4 – and every Renaultsport Clio since – have had electro-steer.
