Dynolicious run in allroad BiTdi

[ukgroucho]

Got my brother visiting from US, he has an S4 and thinks my allroad BiTdi feel 'different but as quick'... "faster in different areas". This is straight line performance obviously - the allroad is still a bit of a barge compared to the S4 so cornering is less precise.

Anyway we decided to do a test using the dynolicious app on hi iPhone. Using a convenient layby on a short stretch of dual carriageway near where I live we waited for no traffic and did some blasts to get a 0 - 60 figure. First couple of attempts I fluffed the launch and got high 5 second numbers, not bad bit not the claimed mid-5 seconds form Audi and also we both felt the pick-up off the line could be a lot sharper... So I decided to try the "turn the ESP off and hold revs at 2800 with the brake on" approach. Not something I would want or choose to do often (if ever) but for the sake of this exercise I did it.

Launch of the line was hugely improved and the dynolicious graphs showed the difference.

We used a drive train loss figure of 15%.. so the estimate of 317hp may be a little high, the 0 to 60 figure is likely to be accurate though and I was astonished

Fantastic, I'm looking forward to stretching my BiTdi when I've finished running her in. Not sure I'll do a launch start, but I can already feel she's begging for some spirited driving. I'm assuming you had yours in 'dynamic' but did you use paddles?

[ukgroucho]

Yes dynamic but used the auto changes rather than paddles.

Mine has done just over 5000 miles now so nicely loosened up.

[ukgroucho]

Oh and the BHP figure... when we though about it 15% drivetrain loss is probably 'low'... and a higher drivetrain loss would result in a the bhp estimate being HIGHER than 317 bhp rather than lower

sorry, but an allroad doesn't need to be as fast as that.
if you are ever in wales, take me for a spin in it

I reckon you should use the paddles and change at about 4600 with the BiTurbo, it just runs out of puff at the very end, but if you change too early you hit the turbo cross over point, so you want to be on the big turbo throughout if you see what I mean.

Cool app though, might give it a look
