Given the Sprint's apparent mid 180's 400 metre end speed potential, I'd expect a 12.50 to 12.60 second 400 metre time to come from a 4.50 second 0-100 km/h time.
For example a GTF Auto (which should have a similar performance profile) was tested in the July 2014 issue of Wheels, and under good 17 degree conditions it achieved an apparently fuss free 4.68 time to 100 km/h, and the 400 metre time was exactly 8 seconds more at 12.68 seconds (with a speed of 186.7 km/h).
Welcome aboard and thankyou for your thoughts.

In regards to the auto GT-F run of 0-100 4.68 sec to 100kph and 12.68 400m if there was wheelspin in that 4.68 0-100 and it recovers well the "8 second" might apply. Otherwise i'm more leaning towards 8.2 as well.

The biggest issue as i know you've encountered when comparing 400m times is the impact of rollout and timing methods.

People are still struggling to compare apples V apples with 400m times and as you know there can be a 3 tenths difference for identical runs depending on timing method.

So for example because the Strip doesnt give you 0-100 times if you mix a VBox timed 0-100 with strip timed 400m for the same run there's every chance you'll get say a 4.5 sec 0-100 and 12.5 second 400m i.e 8 seconds.

The reality is though the 400m time on a VBox is 12.8, so that gives you 8.3 seconds spread.

The other question id like to pose to you is what impact do you think the 30 extra TOB KW that a Sprint 8 has over a Sprint 6 has would impact 1) That 8 second theory and 2) terminal speeds?
