The old in gear argument, 30-70 and diesel torque bla bla bla.
At the end of the day, there is a lot more to comparing two cars than magazine number tests from speed a to speed b.
Take a Leon Cupra TFSi vs a remapped Leon TFSi. 0-60mph is gonna be all but identical due to less grip on the remapped car, but more go when traction becomes available. After 60mph, the remapped car is gonna be off like a scalded cat.
The old Civic Type R vs 150PD argument always pops up now and again as well with in gear times. The thing is though you dont use low revs in a VTEC car so the mag tests are no good. Just because 30-50 or whatever is faster in a specific gear in a 150PD than a CTR, its not to say the CTR is slower as they would be 2 gears down using VTEC.
One thing I have noticed in my time is that ultimately, power dictates the big boys from the wee boys. Normally it takes high speeds in gear 3 and higher to see what is actually faster rather than opportune blasts off the line or in traffic.
The only way you can compare striaght line performance legally and safely is at the likes of a 1/4 mile strip. Then you know the other car is trying, and times to a set distance and speed at that time really does show which is quicker.
