Yep. Thats the problem. A fraction of a second can make the numbers skewed.Just timed it several times watching his video and using a stopwatch app on my phone. It's showing a time of 7.5 seconds 0 to 60. I think there's a slight lag before his phone realises he's moving.
Good point. Is the Speedo GPS value or mechanically connected?Yep. Thats the problem. A fraction of a second can make the numbers skewed.
Even if you stopwatch it your speedo is probably reading 2-3 mph high anyway….
Indeed, a 1970's Porsche 911 S 2.2 would do it in 7.8 secondsFor everyday driving with instant torque, this is more than fast enough IMO.
In years gone by that was hot hatch territory and that was considered fast.
Speedos by law have to meet an accuracy spec. They are not allowed to read underspeed AT ALL but can read something silly like 20% over.
So as a result manufacturers deliberately make them to read at least a couple mph high as if you could make it bang on accurate it allows no allowance for manufacturing variations or drift.
Your speedo is almost certainly optimistic.
On my Peugeot based 2021 motorhome compared with the satnav an indicated 70 is 65mph
Typical overreads are 5-7% for most manufacturers. This means 75 is actually 70.They’re allowed to overread by a maximum of 10% (but must never underread)
20% would be way too much, that would mean someone at an indicated 70mph actually potentially only doing 58mph.
I measure speedo accuracy in every car, I’ve not seen a typical figure really.Typical overreads are 5-7% for most manufacturers. This means 75 is actually 70.

Well not parked at the dealership it wont…..I measure speedo accuracy in every car, I’ve not seen a typical figure really.
Our Evoque is dead on at 70mph, a golf we had was right on the 10% limit.
Not measured the 4 at 70mph because mine won’t do 70mph….
You say that but a few years ago a Ferrari was taken to an authorised garage for a service a few miles south of me and managed to close the dual carriageway a few miles north when it caught fireWell not parked at the dealership it wont…..
My Mk1 ZS EV and my current pre-facelift 5 also match speedo to GPS.As I said earlier, my MG4 shows 70 in both the car and on a GPS app on my phone. My previous Insignia showed 75 in the car when the app showed 70.
I'd rather have an EV:You say that but a few years ago a Ferrari was taken to an authorised garage for a service a few miles south of me and managed to close the dual carriageway a few miles north when it caught fire![]()
