Just as a thought exercise – if you had to pick a new – modern sports car that had proper hydraulic, rather than electric, power steering what would it be?
Just walked past about a 7 year old Audi R8, hence the question. I’m sure the last generation Cayman would have be on the short list... |

..that had proper hydraulic, rather than electric, power steering I don't get it. What are the advantages of hydraulic over electric? I can only see advantages for electric (lighter, infinitely adjustable from the cockpit, no leaks or fluid to check, no burst hoses). There is a big after market biz converting hydraulic to electric. None going the other way. |

What in the world are you comparing to as the baseline for a "good" hydraulic steering sytem? A manual rack is the benchmark for feel, feedback, communication what ever terms you want to call it by. Most modern cars have simply gotten too heavy for a unassisted steering system to be feasible. Hydraulic and Electronic Power Assist Steering (EPAS) are all over the map from OEM to OEM as well as within trim series so I don't know that I'd buy into a generalization hydrualic steering has better feel but I do concede that it is all about personal preference. In either Hydraulic or EPAS, it is all about how the system was tuned. Torsion bar (steering torsion bar - called a T-bar) sizing in either case has a lot to do with feel. Hydraulic has added complexities & tolerances associated to the assist valve griding, hydraulic hose compliances, and even hose routing. I don't miss the days of tuning hydraulic steering systems at all. (IMG:style_emoticons/default/dry.gif) Feel is just as influenced by steering geometry particularly caster but also scrub radius, tire mu, tire tread patterns and sidewall stiffness just to name a few. Steering feel is really a systems engineering thing. No one thing makes or breaks a sytem including whether it is hydraulic or EPAS. I'll still take EPAS for a host of other reasons not the least of which is lack of steering moan (NVH issues) and pump wear issues over time. Let's not even discuss leaks and/or the number of engine fires that have occurred over the years from ruptured hoses that atomized power steering fluid and had it get on hot manifolds. (IMG:style_emoticons/default/yikes.gif) Yup. Don't miss hydraulic one bit. |
