Out of interest, I just checked the stats on my 125Kw 2009 Superb Elegance 2.0 TDI Auto, and it says 0-100 in 10.2 and top speed of 205kmh, but when I've had it on the autobahn, I've easily reached 220kmh!

The speedo can't be that far out, surely?

yes it can

Speedos on most modern cars are about 10% optimistic, so the faster you go the bigger the error.

According to the Skoda UK Site, your initial Figures are incorrect to start with..

... a 125kw (170ps) DSG gets to 62MPH (100km/h) in 8.9 seconds, and tops out at 216.

This is more in line with your real-life 220 top end...

The figures you have listed in your original post, look more like they are for a 140 BHP car....

Also the 170 CR engine doesnt produce 170 hp i've had my totally stock 25,000 mile car on the dyno and it produced bang on 200hp /268.4ft lbs of torque

In line with the PD VRS 170 engine which instead of 170 made 198hp and 283ft lbs with just an aftermarket filter

My E Class diesel with a factory figure of 198hp produced 200hp on the same dyno so its not at all optimistic

Sorry for asking but which filter do you mean?

Use a sat nav to record speed.

Sorry for asking but which filter do you mean?

Air filter for the octy I'm currently using a k&n

We removed the air filter from the Superb and did a dyno pull without one in there at all (on the basis that nothing can flow better than that) ....it lost 2 hp

Speedo is likely to be up to 10% out

They are never accurate they can never be accurate if you think about it ie tyres and other components wear , Sat navs are also not accurate they are sometimes but not always better than speedometers depending on how good the satellite reception is

I once bought a motorbike that was incredibly fast and I was very very impressed with it until I noticed that all the cars and even the odd truck were overtaking me at over 100 mph on the motorway. I had fallen for the least expensive tuning trick in the book - doctor the speedo.

Yes, most cars have optimistic speedos and since the law allows 10% error then they are keeping within the law to make them read high. Like, I suspect, most people I use a tom tom and calibrate the speedo of the car (my SEAT reads 75mph at 70 for example). The Superb had the most accurate speedo I have come across, being only a few percent optimistic .

But top speed is so easily influenced by external factors such as wind speed, slight slope of the road etc I would not too excited about what I saw on the spedometer. There is a reason, afterall, that for a land speed record to stand you have to record an average speed going both ways.

Oops! Yes, it is the 170bhp engine, I got confused with kw/ps/bhp mix... :-(
