I compared 3.0T vs TDI in 4 different performance comparisons - here are results
Recently I logged both a Q5 3.0T and my TDI on the same strip of flat, straight road, in comparable temperature, etc. Every test I did 2 passes in each car to ensure results were repeatable. Here are the tests I performed and the results below. Enjoy! :D
1.) 0-100 in "S", ESP off (w/kickdown) > Scenario: Fastest off the line (eg 0-60) 2.) 45-100 in "S" (w/kickdown) > Scenario: Similar to a common B5S4 testing range. Fastest possible from that starting point. Street-racer type comparison. 3.) 60-100 in "D" (w/o kickdown) > Scenario: Highway passing; quickest in civilized (no "S" or kickdown) manner (ie wife in car) 4.) 60-80 in "M8" (w/o kickdown) > Scenario: Top gear comparison. Here are the details for each... I posted the most relevant graphs for each but there are a few others at the links in each section. Click on those and scroll down until you see populated graphs. This is a template I've used in the past and only used it this time for time/RPM/Speed data. 1.) 0-100 in "S", ESP off (w/kickdown) > Scenario: Fastest off the line (eg 0-60) Here we see 3.0T about 1/2 second faster than TDI,which matches specs roughly. Absolute values are a little slower, but that could be due to various factors. At least relatively, they are as expected: http://ctny.audiworld.com/mark/q5/mi...ph_summary.png I then decided to try applying some brake-torque in my TDI (I didn't try with 3.0T), and got the revs to ~2500 RPMs before letting loose. That gives a more sensational/responsive launch and results in a best-result of 6.13s 0-60 (added Green data): http://ctny.audiworld.com/mark/q5/mi...ph_summary.png and here is full 0-100mph (well 98): http://ctny.audiworld.com/mark/q5/mi...ph_summary.png I only ran the brake-torque pass out to 88mph, and somewhere around 70mph the 3.0T caught up and then surpassed. If the 3.0T had also brake-torque from the beginning, it may have been better throughout - maybe. All data here: http://ctny.audiworld.com/mark/q5/mi..._vs_30t_0-100/ and with brake torque here: http://ctny.audiworld.com/mark/q5/mi..._vs_30t_0-100/ 2.) 45-100 in "S" (w/kickdown) > Scenario: Similar to a common B5S4 testing range. Fastest possible from that starting point. Street-racer type comparison. > Note: I screwed up and didn't go into kickdown with TDI. I'll redo this test again. I confirmed last night that at 45mph in "S", flooring it w/o kickdown goes into 4th at 3000 RPMs, while with kickdown goes into 3rd at 3600 RPMs, confirming my logs are w/o kickdown. TDI gets the jump and is quicker to about 70mph and then the 3.0T is quicker after that: http://ctny.audiworld.com/mark/q5/mi...ph_summary.png Here you can see the early acceleration jump the TDI gets: http://ctny.audiworld.com/mark/q5/mi...3_image027.png All data here: http://ctny.audiworld.com/mark/q5/mi...vs_30t_45-100/ 3.) 60-100 in "D" (w/o kickdown) > Scenario: Highway passing; quickest in civilized (no "S" or kickdown) manner (ie wife in car) Basically even from 60-75 and then the 3.0T starts to pull away: http://ctny.audiworld.com/mark/q5/mi...ph_summary.png All data here: http://ctny.audiworld.com/mark/q5/mi...vs_30t_60-100/ 4.) 60-80 in "M8" (w/o kickdown) > Scenario: Top gear comparison. No question, all TDI :D http://ctny.audiworld.com/mark/q5/mi...ph_summary.png All data here: http://ctny.audiworld.com/mark/q5/mi..._30t_60-80_M8/ |
All hail the 3.0T :D
Nice data Mark. Thanks. Also, "brake-tourquing" the 3.0T would have helped with the times, like it did with the TDI. |
Interesting info!
The 8 speed actually has launch control documented in the Q5 manual (or it does in mine at least). It basically extreme torque braking and caries a warning about not doing it too often. The procedure is pretty much common sense; 1. If you have ADS put it in dynamic, otherwise just box in S 2. ESP in off road mode 3. Brake hard 4. Mash throttle until revs settle (about 3k on mine) 5. Release brake First time I did it I was genuinely shocked at how fast 2 tonnes can get moving!!! I have done it with the box in M as well, and it shifts harder than S, but not sure if it makes much difference to the 0-60 time. Note that I have found going to M from S makes it shifter harder than going to M from D - I can't work out if this is just in my head yet though! Would be interesting to see the 0-60 graph with full LC ;) |

Mark,
Could you explain for us novices how you capture the data (speed, rpms, time). Is it via the ODB port using a data capture device? Very interesting work. Dennis |

I have yet to read my manual but this was taught to me by my audi specialist when I picked it up and he was training me on all the features. Haven't done it yet but I will log some data with torque for android. I have less than 750 miles; I was going to wait until I hit 1k, but that could take another month or two. I have the 2.0T so I'd be happy with hitting the published 0-60 times.

Yes, using VAG-COM, go to "Engine" then "Adv. Measure Blocks", then select items of interest and log. It saves it as a .csv file in the install/logs area, which you can then open in excel to graph, etc.
