Clearing out Berlingo (1.9D) in prep for moving holiday campsite tomorrow I clocked fact that speedo goes to 130!!

That's a good 50mph more than I've ever got out of it.

What's your car's 'optimism gap'?
 Speedo - Max and Reality - ....
You're forgetting the Berlingo 3.0 VTRGTXGTi which does 200mph with a jet engine in the back.

My car has a 160mph speedo and a limited top speed of an indicated 137mph, 130mph GPS actual. Red line is at 4600 rpm and will not physically go passed that which is the indicated 137mph.

I had a FIAT Coupe 20v turbo which indicated a 160mph max and the speedo would wind past that. The car did have 343PS against a standard 220PS which was good for an indicated 155mph.

* All above speeds were on unrestricted Autobahn before SPEED and anyone else goes into meltdown. I would never attempt these speeds in the UK as the dozy, idiot proof UK test ensures anyone with a pulse gets a licence and the bonus of extra taxes.

To the speed kills people, Germany and it's unrestricted Autobahnen is a figment of your enemies imagination it does not really exist. 71mph and you WILL fall off the planet.

Just to add my bike doesn't have an indicated max, just a digital readout of what you are supposedly doing.
The only constant is the rev counter which goes all the way to 16000rpm or 14250rpm if you're being sensible.

Just to add those dealership add on waxes may not be such a bad idea knowing how leather behaves at 165mph compared to the materials which have you physically shifting this way and that through drag. Leather's the future...

160 mph on the 3 Series, not coghin' nuffink, 140 on the GS - probably in excess of a 110. 120 on the Scoot - probably about 80, Digital speedo on the Street Triple - no more than 70 (yet)....

You know if you fancy a proper blast on the 'Ring you're both more than welcome. Just not in August as we're off to Imola with the D5, wife thinks it's a motoring holiday....so more track stickers for Humph on my return...

My best was about 4mph past the end of the speedo on someone else's F-reg 328i many moons ago (calibrated to 150) on the German A6 Barton-le-Clayhof bypass, and the same +4mph in a Fiat Panda 1000S (max 100) on the equally Teutonic A1 south of Langfordstein. That actually felt faster..

Saw an indicated 122 in a 1.8 Escort with dials showing up to 140, 3am on the M1 autobahn near Nottinghamstrasse on a maternity run. Also seen 130 in a Mondeo with similar 140mph dials on the M1 early one summer evening past Northamptonstadt.

I drove an S-Max Powershift auto TDCi today, I thought the speedo calibration to 160mph was somewhat optimistic, it was gutless to say the least. I'd be surprised if it would crack the ton. On the flipside I took out a Jag XKR-S last week, its dials went up to 220mph and from the way it went I daresay the car would readily poke that indicated figure in the ribs.

LSEC will do an indicated 120mph now it's had new tyres, but I won't really stretch it until it's been serviced.

Funny you should mention that, a certain VauxhallOpel Vectra heading to StahlStadt managed 122mph whatever that is in kph on the Autobahn Eins when a lot of other cars were restricted to 112kph. Baby due, nurse was misses at the time.

Dunno what I was doing, but hit the rev limiter in top in a formula first at Silverstone.

Ford Kent engine in what was basically a long go-kart clad in fibreglass.

Neighbour arrived home tonight on his Street Triple while I was unloading the boot.

When he switched off it gave three beeps. What's that?
 Speedo - Max and Reality - R.P.
Ours does that - there's a sort of electronic clicking and then the three beeps. Asked the question myself and no answer has been forthcoming !

The quoted maximum speed of my car is 138 mph, and the markings on the speedometer go up to 150 mph. However, if the speedometer reads 10% fast, the theoretical maximum reading will be 151.8 mph. And what about if the car is going downhill with a following wind?
On the banked circuit at MIRA I've saw the needle of a 1950s Mk1 3.4 litre Jaguar point vertically downwards, which was known as "going past the maker's name".

thats the maximum 138.
 Speedo - Max and Reality - Mike Hannon
The XJS speedometer reads to 165mph and the handbook says maximum speed is 161mph.
I'll never know (although I have, just once as an experiment, seen an indicated 125mph).
 Speedo - Max and Reality - R.P.
The original XJS was tested by Autocar to a 153 mph - I was an anorak in those days

Downhill with a following wind my brothers mini could do Full mph, think the speedo only went up to 90mph.

My vintage car speedo goes up to 80, and it was supposed to be able to do it. I've not been past 60.
 Speedo - Max and Reality - Mike Hannon
>>The original XJS was tested by Autocar to a 153 mph - I was an anorak in those days<<

Mine is one of the very last 6 litre cars. It's apparently a very different (Ford re-engineered) motor. Jaguar says 164mph for the coupe.

As I said, I'll never find out.

And the original one was a carb breathing monster....so maybe a bit wheezy ! Still want one though..

4 x Stromberg, used to take me all morning to tune a V12, few and far between though, fortunately!

My '86 Camaro speedo maxed out at 85mph, got it round to about 40mph on the second sweep, haven't a clue what speed.

'86 (good year that) MAN F90 artic tachograph maxed out at 75/80mph, calculated on rev counter lorry would actaully cruise at 95, tacho records its set max..;)
 Speedo - Max and Reality - Zero
Mine is marked to 130, I have had the needle 15 shy of that

When I was a wee lad a neighbour had a BSA Bantam with clip-ons! The speedo maxed at 55mph if my brain isn't failing me. I remember being mighty impressed.

LandRover speedo goes up to 70.
It's possible to get the needle on the end stop downhill with a good wind.
 Speedo - Max and Reality - -
That takes courage Cliff, my series 2A LWB ex WD would run up to about 75 but keeing it on your own side of the road got progressively more difficult as the speed shaking vibration and noise got to crescendo levels.
Ex hot service too, full canvas no heater...brrrr.

300ZX had a speedo max of 180mph. Top speed IIRC was around 130mph.

I remember back in the day a Series I Cortina 1500 estate, hired and almost new, that went very well indeed. But over Salisbury Plain, driven flat out for miles, the actual road speed varying by very little, the speedometer needle oscillated wildly between 90 and 120mph. I reckoned the true speed was well over a genuine ton anyway.

Terrific gearbox too, learned clutchless gearchanging in muddy lanes without breaking it.
 Speedo - Max and Reality - Slidingpillar
Ford gearboxes of the period had a superb reputation. 2000E box, solid lever and a quick shift kit and you'd have to spend a serious wedge to better it. Plus the 2000E box was pre the silly German caravan rule, so you got a sensible set of ratios.
The Germans required a hill start with a laden caravan up a specified slope and as a result, silly low first gears and yawning gaps resulted.

>> LandRover speedo goes up to 70.

I have memories of an early LR speedo which went up to 65. ISTR going down the recently opened M62 towards Leeds with the needle down the bottom somewhere near either the oil warning or main beam light.

That kind of noise is probably a contributory factor for my tinnitus :-(

Contrasted with a basic 1.2 HTP Fabia which would probably manage just over 100 mph, but the speedo goes to 160mph.

You and gb must be better men than I.

My series 3 made your ears bleed and shook fillings out at 50, but that wasn't the limiting factor. It just felt frighteningly dangerous, and I had never cured the tendency for the rear wheels to lock under braking which also concentrated the mind, so I never went any faster. The Kingpin remoulds might have been a factor.

It had parabolics on it when I got it, the pal I bought it from said the ride was positively luxurious compared with it before the swap from the original type springs.

Mine was an 88" pickup, short wheelbase and usually no weight in the back. I did drive a 109 hard top, which was nowhere near as scary, but wouldn't go faster than 60.

The LR in question was the best of the bunch belonging to a broadcaster in Manchester.

As I recall it was a petrol 108" series 2 with no synchro on first or second (by design). Quite why it went so well compared to the others of a similar age and specification was a mystery to the Transport Manager/mechanic but everyone who had to drive one knew it went well, and fortunately it would stop too.
It was unbelievably noisy though.

There were also a pair of petrol 88" versions which were little pigs that wouldn't go in a straight line for love nor money. One of which did 12 mpg, the other did about 25mpg.

(the "driving test" before you were allowed to use one of the LR's was conducted by the TM and involved keeping one of the SWB's on the left hand side of the road somewhere around Longsight/Belle View in Manchester: if you managed, you passed, provided you hadn't broken the gearbox.)

All a while ago - probably circa 1974.

The MX5 speedo is indexed to 150. The red line is at 7000rpm, and 70mph comes at 3500 in top.

So clearly the top speed is 140 ;)

I think the claimed top speed was actually 130, but I'm not testing it. It's far more fun at 40 or 50 around twisty bits.

Not necessarily. When does the rev limiter cut in?

I haven't experimented with that, in case the rev limiter turns out to be a valve spring or the belt!

Mazda B series engine, same as in my old Kia Pride and I saw over 7K on the rev counter in that quite often - carb and dizzy so no ECU to run out of parameters.
