Just an idle question really, has anyone taken the GR86 up to V-Max where it stops accelerating and stays at it's 'top' speed?

(obviously on an unrestricted road, so Germany really)

Official figures says that 140 mph (225kph)
 
It's 228 km/h on 6th gear.

The tachometer is dead center at 6K RPM I believe? I've read somewhere, that in Germany, tuner was able to lift it and overall car is capable going beyond 250 although it's very slow at this point. Gearing itself is set to around 275 km/h on 6th gear but car is nowhere capable of achieving this speeds in stock form.

It's electronically limited to 140mph isn't it? With 230bhp and the gearing in 6th surely over 150mph should be achievable.

Even my 140bhp Audi A3 managed 140 on the autobahn.

I managed 136mph with the car fully loaded on a windy Autobahn. Still passed by old Passat estates and Merc Sprinter vans. Also, the SUVs on the after school run

Got 138 mph on the autobahn today, pretty confident it would have been 140 if I didn’t come onto a hill! 😂 It gets up to this speed pretty well and as mentioned above the tacho was just shy of 6k for me.

The German M340d in front definitely hit 140, in fact he probably ran into his 155 limiter! 😂 Was joined later by an i5 touring and RSQ5, all of the above in black so it was bit like a vip convoy with me tagging along! 😂

Allegedly (discovered by German tuner mentioned earlier) on 6th gear above 200 km/h, car throttle opens only up to 80% even with gas pedal fully depressed. That might account for additional lower acceleration above that speeds.

I have no doubt in the 140mph top speed. I havent been on an autobahn with the turbo kit. Tuning developments said they hadn't intentionaly removed the limiter but i guess it may have been removed as part of the reflash. If i ever find out I'll let you all know.

Yes, 141 yesterday and it just held there. Had the space and time for it to increase and even a slight decline in the road but it just held steady.

The GT86 was limited to 140mph via the throttle map (reduced throttle % to limit speed). Our cars with the extra power should sail past 140, so assume limited in the same way.

A 2.7 boxster with similar power/weight, 0-60 time would hit closer to 160mph, so assume we’d see similar with the limiter removed.
