Does my car have an engine cut-off at max speed/revs?

Hi guys, just a quickie to follow up on my trip back to Singapore last Thursday. On my way down, I was lucky to hit a lovely long stretch where I was able to really put my foot down. The speedo needle hit its max of 185 kph but I was still accelerating. Obviously the speedo was beyond its capability, but as I was then travelling at Warp 10, the engine suddenly cut itself off. Just for a second it felt like there was no power, (no bang, no jolt), which of course made me immediately take my foot off the accelerator and slow down.
I panicked a bit, and nervously scanned the dash for a warning light but there was nothing to see. The rest of the trip was pretty high speed, but as the traffic had picked up, I didn't open her up like I'd done earlier.
Actually, when I stopped for a coffee and a ciggy an hour or so later, I gingerly opened the bonnet to see if anything looked amiss, like oil sprayed everywhere or a piston stuck out of the rocker cover, but to my untrained eye, all looked okay.
She's run fine since, so this is why I'm asking if a 'cut-off' system actually exists.
If anyone of you gurus could let me know, I'd be grateful.
Thanks, Si.

Is your a JDM? They are limited at about 114mph, which is about 185kph.

Morning @Vtecmec, Yes sir, she's a JDM. Thanks for letting me know. Brilliant, I haven't broken it then.

lol yeah its a soft cut limiter

Yep, all's well and functioning as it should I always believed it was 112mph/180kmph.

Most kmph to mph converters can remove the limiter.

Surely even without the jdm limiter, the car would run out of power and not be able to exceed a certain speed/rpm before it blew up.
Either that, or it would hit the rev limiter in 5th hahaha.

As above, speed limiter or rev limiter hit.
Entirely normal.
And in answer to your question in thread title... Yes, the car has both of those!

Many thanks to you all for the fab feedback. As ever, it's much appreciated.
