75-80 mph in second gear !?!

Morning Chaps,

Managed to take my Chimaera 4.0 out for a bit of a blat yesterday.

Once warm and happy, I had a bit of sport around the dual carriageways in Milton Keynes with a new F type jag, and at one point I looked down to see the speedo in between the 70 and 80 marker whilst I was in second gear.

After myself and the F Type were done I tried again to see if I had confused matters in my head, and lo and behold 70 was easily acheivable in 2nd gear, more if you wanted too.

I don't know if it's the gearing, or if the speedo is hugely out, but thought I would ask on here until I can get the oppertunity to try again with a tom tom in the car.

I borrowed the wifes Cayenne S to come to work this morning, and at 80 on the M1, i tried to shift down to see what sort of gear that would sit at 80 in, and by the time I'd put it in third it was getting very shouty (near 7000 rpm) and that's a 4.5 V8.

So, do these cars just have huge gear ratios, or is my speedo well out?

Thanks for the heads up, although for me 80 really is the limit for me in the Tiv on dual carriageways anyway.

Also given the nature of the beast, and the respect I have for the car, hoofing it in a bend or a roundabout is not on my agenda. Straight line drag I think if the torque would break the traction it would be fairly early on 1000-2500rpm, I'd have thought that by the time it was 4000 plus if the wheels weren't already spinning (lost traction) it's not likely too unless you hit ice or diesel etc.

I do understand that coming off the power in a bend can also induce balance issues as a result of hefty engine breaking, however once again, lifting off at high speeds for me is mostly done in a straight line.
