Electric power steering
Ok so from this pic
http://i223.photobucket.com/albums/d...n/e63e7a4a.jpg we can see that the FT will have EPS. my immediate reaction is :thumbdown: , of course, but then... https://docs.google.com/viewer?pid=b...mber=17&w=2000 it turns out the LF-A has column mounted electric power steering! conventionally, column mounted has the worst feel over pinion mounted and rack mounted, but the LF-A has great steering feel!!! THIS is why you have a halo car. THIS is why the LF-A costs so much. they've managed to make electric power steering great. so all those hours spent tuning the steering? it trickles down into $20k cars like the FT, hopefully :thumbup: so what does all this mean? it means toyota knows how to make EPS great. sure a corolla or yaris isnt going to have similar steering feel/EPS tuning, but the FT was made with the same sporting intentions as the LF-A. it's supposed to be a bac to basics kinda car with as little intervention as possible. what better steering system to emulate? it would not surprise me if the steering of this car turns out to be LF-A good. and for an EPS system? that is HIGH praise... |
The column mounted EPS was also one of my main concerns about this car.
I've never realized that the LFA also uses the same type of EPS system, but if Toyota can do it then lets hope they also do the same with the FT86. :clap: |
Are you sure the power steering is done by toyota? Subaru also makes an EAPS system.

My RX8 has electric power steering, it feels great.. This is different to drive by wire ;)

As long as we're talking about the steering system, this is a patent that was published last week assigned to Fuji Heavy Industries (Subaru.) As with many patents, it tends to be rather vague as to what vehicle it goes to. That in mind, it describes a system for mechanical steering.
Quote from the first page: "Moreover, since the steering gear ratio can be changed mechanically without performing motor control, the occurrence of control delay can be prevented, thereby reliably preventing deterioration of the driver's operational feel" So whatever car this system is going on, it seems like they really want road feedback and driver experience to be key. Which, seems to be what they've been saying all along for the FR-S/BRZ/Whatever. |

And here's another patent from Fuji Heavy Industries describing an electric power steering unit published back in July.

As long as the variable steering is quick for all but the very extremes of wheel angles (yes I'd prefer non variable as well, but in this world of EPS systems I'd love ANY mech system instead!) then I think it'll be great to have the system that patent is for... and it does seem like a potentially good sign that the patent seems focused on driver involvement, exactly what Toyota and Subaru say this car was designed for. |

But, on the other hand, I don't want the system to be so mechanically stupid as to be almost impossible to turn the wheel when the car is stationary. It was a workout to wrestle with the wheel in my old Toyota pickup. |

The difference is that the steering is power assisted with electric motors instead of using hydraulic pumps. All in all this is encouraging news. :) |
