Does the roadster have power steering?

    I did a search, and found a post that implied the roadster did not have power steering, but it wasn't very explicit.

    I drive an MR2 Spyder, which absolutely does not need power steering, but has it anyway...and so I was wondering - did they juice the roadster's steering rack?

    No power steering. But I drove it and it really did not need it - even for a U-turn.

    On my drive I never noticed that it didn't have power steering. I did like the road feel. I consider the lack of power steering a positive, but I'm a bit of a sports car performance purist.

    The non-powered steering in the Roadster actually feels quite good on the road. The lack of power is mostly noticeable at very low speeds moving in and out of a parking space - but even that is not horrible.

    Awesome - thanks for the responses. I prefer manual steering as well as most of you, and have been planning to convert the MR2 to manual steering.

    I assume the S will have power steering (holy $#!* those wheels are gigantic) - wonder how much that will hurt mileage...

    I think the low speed steering might take a little more effort if you get the sport tires.

    I've got the sport tires, and getting around the parking lot is a bit of an arm workout - getting used to it, though. But I absolutely love that there is no power steering! I, too, am a purist.

    SByer,

    question to the performance tires: is it true that there is a manufacturer suggestion not to go faster than 80km/h with them in the wet? Did Tesla mention anything in that way when they handed out your car?

    Heh, no mention of that, but yeah, looking at them, I wouldn't take them over 80 in heavy rain. They may not be racing slicks, but there isn't a whole lot of depth to the pattern, they look like they'll plane really well.

    They did, however, do just fine on wet mountain roads.

    It's something I can inquire further about when I go back in when my black wheels come in.

    isn't 80 kph more like 40 mph or do I have my conversions backwards ?!?!?! :eek:

    80 kph = 49.7 mph

    You're right, didn't notice that. I don't think they're that bad - I don't think I'll worry about getting up to 65mph with them in the rain. I figured I'd just take the typical light sports car, wide tires and rain precautions.[​IMG]

    Just remember that higher pressure in the tires helps reduce hydroplaning by creating a smaller patch on the road. For the rainy day, I would take the pressures up a little over the recommended range pressures of 30 PSI front/40 PSI rear.

    After the temperature rise from driving, if the pressure goes over 50 PSI, the warning screens are pretty annoying. To avoid this and to stay safe, I would not put more than 45 PSI in the tires when cold.
