STR - 400bhp limited top speed 155 mph. No one in their right mind would attemp to go faster (well, not me!).
However, i wonder what speed would potentially be possible without limitation. Has this ever been tried? Did Jaguar ever test this back in the day?
Just a thought 😎

I'm sure I recall Jaguar calculated that it might hit 193 mph. All this would be with a long enough road, which I'm sure includes no wind of any kind & being able to keep the front & rear ends on the ground.

I can confirm that mine didn't bother about being limited to 155, it romped right through that.
I did read that the limiter is a soft one that reduces power rather than cutting it at 155 and also I don't believe it applies in 5th gear anyway.

I've had 157mph GPS on mine, not sure if it is limited or not, being my 3.0 has a slightly different MAP and the limiter moved up so i can lock in 5th which helps with the top end.

That was on a section of the A9 near Munich ;)

Got from there to Lepzig in short time! :ROFLMAO:

cruising in silence happily at 135 :love:

wouldn't mind a go in the STR ;)

I've been told on good authority that the STR is drag-limited to around 175-180mph, but getting those last 15-20mph out of it takes a lot of road (Autobahn run). The trick was to have it in Sport + 5th gear
