What is the time difference between online/offline lap times?

It's a common fact that online lap times are slower than offline lap times in GT5, but question is: how much slower are online laps in average?

Also, after the 2.07 update, it has been said that online/offline physics are much more similar. Is it true? Can I test a car offline for online racing, or should I only test online?

Short answer: it varies.
 
If you are planning to drive the car online there is little point in testing or tuning offline. The physics are different enough that online will typically require a tweak to your tune anyway. Tune/test online only and save yourself time.

If you want to run the car both offline and online then you might need to test in both situations and use the saved settings to create specific tunes for each. That's what we end up doing in the GTP_WRS (Weekly Race Series). We typically run a time trial offline for a week and develop offline tunes and then tweak those tunes the next week for the online races. In some cases we throw out the offline tune all together and create an online tune from scratch, in other cases a simple change of ride height is all that's required to make an offline tune work well online.

Offline is faster and the difference varies quite a bit based on the car and track and the settings you use are also a major factor: fuel consumption/tire wear, grip reduction, etc. Having said all that, for a car/track where you are running a 1'45 lap time offline, it wouldn't be surprising to run 1'46-1'47 online with similar settings, so 1-1.5 seconds, but that is just a rough gap to give you an idea.

Agree with all of this, in particular saving online tunes and offline tunes separately. In my experience you get a bit more oversteer and wheelspin when driving online.
 
I sometimes practice off line with the ghost in time trial leading up to events. Depending on the track and car/tyres the times can be up to a second difference. Like WRP said once online the tune more often than not needs some tweaks.
 
To throw some real world times in the mix. Here's one data point from one of the fastest drivers in the world who takes part in our events (Twissy -- you may recognize him from the leaderboards in GTA).

Twissy won our time trial a few weeks ago at Monaco running a 1'37.464 lap (results).
The next week in the online race his qualification lap was 1'38.746 and best race lap was 1'38.863. (results).

I think the quali lap is a bit more comparable as during the race he would have been in traffic or saving tires and draft was not much of a factor in this event.

Note that the the WRS offline events do not use the tire wear / fuel consumption option where that option is forced on for the online races which contributes to the fairly large difference in times. Add to that drivers have a week to run their best lap for the time trial whereas only 2 hot laps laps to qualify so there are quite a few other factors in play here.

And yes, the ghost is one very good reason to run offline and find out where you may be losing time and trying out different lines.
 
Agreed. The fact that Twissy got about 1.3 off his actual TT time is very good. That's why those guys are number 1! lol

Once tyre degradation and fuel is switch on for offline, the times and feel of the cars is a little closer.
