Does anyone know the correct top speed for the Tuscan. The latest evo mag has got my thoughts going. Is it more 185, does it struggle to 180..... or over 190?? Anyone who''s maxed one thoughts please

hmmm unless anyone else has fitted a gps system to theirs, then its rather dodgy to rely on the speedo reading... Indicated and actual are generally pretty different...

What about all these other cars? I'm sure it's not just TVR. Such as the RS4 which a magazine had up to 170 something on the speedo - I wonder what that really is.

Surely most (German) cars have ECU speed restrictors. Thus max speed *is* 155Mph. Waiting for the flames..... Sparks

Given that, roughly, 3500 revs = 90 in 5th gear (non close-ratio box) and it is fair, I believe, to assume that (real) speed is proportional to revs, then 7k revs ought to equal 180mph Anyone had the red light on in 5th yet?

I've had all three change up lights in 5th gear on the Autobahn on a number of occassions, with a best of 72(00) rpm showing. (Somebody always pulls out half a mile or so in front of you, so you have to lift). My speedo stops working at circa 130-140 mph, so I don't know how fast, although if I were good at maths I could work it out. I've sent an email to Evo, reference their (non) article and asked them to do it again, properly this time.

1000rpm is approx. 40km/h.

And what happened when Evo tried to go really fast? It broke. Well, I'm shocked.

no flames, but not quite right. There is a sort of gentleman's agreement to limit the top speed to 250 km/h (= ca. 155 mph). But this is not law. Porsche, for instance, does not adhere to it. Rgds, WalterU

I couldn't agree more. What's more - you stupid can they get?!? The english are very cosmopolitan, nearly every englishman I have ever spoken to knows someone who lives in Germany - at least temporarily. I am sure the EVO people could have found someone to ask, and that everyone could have told them that the Dortmund to Kassel autobahn is one of the busiest and therefore stupidest choices for such a test.

Could you enlighten us on a better stretch of road for safe high speed driving? [I don't happen to know anyone in germany myself, though I have a fair few swiss connections, but they couldn't tell me anything useful. Still they all seem to drive 4x4s...]

A couple of places on autobahns in Germany that seemed fairly traffic-free were the ones going north out of Hamburg towards the Danish border and towards Puttgarden, along with another that goes towards Luxembourg south from Koln (Cologne) and which also goes past the Nurburgring. I pretty much maxed my V8S a few years back coming back from Denmark to catch a ferry from Hamburg, and then early last year bottled-out in a Griff at c160mph uphill & still pulling on the other one.

first rule is - do it in the height of summer, at 4am in the morning (it gets light then). Possibly the best motorway is the A31 from Bottrop to Emden. Forget any motorway in single figures such as the A1, A2, A7 The Hamburg-Puttgarden route has speed limits north of Lübeck. Don't break speed limits in Germany - the german police are even worse than the brits. Rgds, WalterU

My max mph on the digital now reads 182mph in
the S, this appeared at aprox 7k rpm with all
three lights on. The analogue was somewhere
around the same mark no more than 10mph over.

as max power is at 7k how is it supposed to
hit 195mph?

It was still pulling but it is difficult to find
a clear enough stretch of road, often have 170
though.

The car is incredibly stable actually had my other
half with me who was not at all nervous whereas lesser
speeds in the previous tuscans and chim500
had a somewhat different effect. We were actually
paying Christof a visit and was very impressed
with what he has done to his 4.5, it is one quick
car with much less nervous steering at speed than
the tuscan.

I also got a max of 182mph on the digital speedo at Elvington airfield trackday earlier this year in my Tuscan RR. I think I was on about 6700 rpm and it was still pulling like a school boy, but I had to brake for the corner...

Very stable at that speed, mind you it was a nice flat airfield, feels a little less stable on the road.(lower speeds of course!)

Must get a longer airfield next time !

6.7rpm sounds more like it, I'm a bit concerned about
the gearing, is there different final drive options?

What speed do you get on the digital readout in 5th
for some fixed number of revs so I can compare.

I wonder if the rev counter is a bit out?

If the power available is enough to counteract the drag then speed will still increase until power is equal to drag (or you run out of revs).

If 1,000rpm = 40kmh then at 7,200 rpm =288kph=180mph.

So what is it re the evo article...Does this mean that Tuscan owners can no longer brag about doing 200 mph, as they are probably only nudging 160 etc. etc.
Funny how a few years ago it used to be TVR owners who's inferiority complex made them snipe at Porsche how times change eh? R...

I had a blast in a Tuscan S and bottled it at 140 the car was all over the place, still had alot more in it though, have TVR done any proper test for top speed etc... the only article I saw was a Tuscan S v a GT2, the GT2 pulled away from the Tuscan at around 110 mark but no top speed figures.
