New TVR still under wraps!
Discussion
just made the switch from the hydraulic PAS to Saxo Electric PAS and to me its a big improvement.
Engine load= better
Steering Feel= better
overall assistance better
All IMO but the best thing for me was perhaps not doing an immediate back to back test as the difference may have been to sudden... however after at least a 4 month Cerb free time to getting car back it feels not to different weight wise to I remember however it just feels MUCH better!

You still have a hydraulic steering rack and manual column...Engine load= better

Has anyone else noticed the electric power steering module (column mounted)?
PS- Electric TVR has already happened- see Top Gear
PPS- aside from the above TG effort, electric cars are mega performance wise and can be very nice to drive.
F type was my first thought?PS- Electric TVR has already happened- see Top Gear

Not wrong there Iain, and soooo Aston, not surprising given LE's association with the marque and the GT racing connection... The renditions of new TVR I've seen all look Aston inspired to me... here's mine side on... (sorry, can't resist a pic opportunity...)

I doubt you'd mistake the new TVR for an Aston. For a start there's the...In fairness all front engined 2-seater hard-top fastback style cars are going to be pretty similar in silhouette. But in the same way you'd be hard pressed to mistake a Corvette for an Aston, I don't think you'd mistake the TVR for an Aston...or a Corvette for that matter.
And re the electric power steering comments also on the thread - the beauty of electric power steering is you can turn it off...assuming TVR offer an off-switch, and not too difficult if they don't if you really do want the ultimate in touchy-feely steering. My Tuscan does't have power steering and while it's a PITA at slow speeds, even on slicks it's unnecessary on track days. I was certainly plotting a switchable electric system for it.

And if you do that, you get all the downsides and no advantage at all!The issue is inertia. In order to meet the peak power requirements (parking (slow speed wheel scrub), and major limit handling wheel twirling) the electric motor has to spin fast (speed = power) and so requires a high gear ratio (lots of turns of the motor for a given movement of the rack). And that means the motor's inertia is referenced to the rack by that same ratio, so even a nice low inertia brushless motor adds significant inertia to the system.
The main reason early epas systems were criticised for a lack of feel is because of that inertia. Later systems have more powerful motors an faster control loops to allow the motor to negate it's own inertia, even if it isn't providing assistance. So if you "turn it off" you get horrible sticky, unresponsive steering.

Why isn't a viscous fluid coupling between the motor and the rack used? That way, small feedback movements won't be dulled by the motor inertia, so the complication of it having to be compensated for is negated, but large movements/high assistance levels will be handled as required.The issue is inertia.

Five weeks today, and the wait will be over. Starting to count the days??
Another good article in this week's Autocar, all looking very promising.
The ways prices are rising it seems that buying a new one might end up being the cheapest way into TVR Ownership.Another good article in this week's Autocar, all looking very promising.
Be a mate Nigel and see if you can get some inside info of the shades of RED that may be available please
Will you be taking the TVR Motor home ?

Ken, I hear that they will be offering a Slip-Stream red, especially for those at the back, a Tango Red for those that like to Tango, (sorry, your secrets out!) and Tutu pink for the Brave(Ken)Be a mate Nigel and see if you can get some inside info of the shades of RED that may be available please

Yes, going down in the MH, it could be the ultimate tow car

It's getting exciting now isn't it.
For all the so called neasayers everyone involved with a Tvr must be hoping they produce a Tvr worthy of the name, GM designer you couldn't really ask for a more British and world beating designer so so it all points to a brill car.
Prices of second hand Tivs will be higher come the reveal I'd imagine so maybe we all benifit in the end.
Rather selfishly maybe I'm really hoping the press jump allover it and remind the world we're still here and even more egotistically more people recognise and agnowledge Tvr as a great car.
Tvr sad demise but legacy and ongoing endearing love of these cars by committed Tvr folk has kept the mark in rude health considering.
If the new Tvr can capture all that's good about the older cars and add that modernism that many of us have actively added to our older cars bringing them right upto date and allowing for reliability as a norm would be just the car we need.
If it turns corners your on a winner and Gordon knows all about that.
Good times ahead could be just round the corner.

In a bizarre way, if the reveal car doesn't grab me it will be easier all round here, particularly with not having to continue fantasising and Mrs P asking why I'm staring into the middle distance all the bloody time!
We shall see.
Edit: I shall be taking a cheque book just in case the opposite happens. Plus tin helmet for the journey home.

It certainly is getting exciting! I'm in no position to afford the new car, but I hope to be going to Goodwood specifically to see the unveiling.

Kids even now still shout "That's a TVR!" when I drive past, the brand lives on, the future is there for the taking!
