Many automotive journalists do not so we are not singling them out but right off the bat there is a massive flaw. It is called traction dependent results. What this means is the result will be different based on who gets the best launch.
The Alfa Romeo gets the best launch and wins the drag race with an 11.9 second pass. The F80 M3 trails it at 12.3 seconds with the Mercedes-AMG C63 S bringing up the rear at 12.6 seconds.
Where are the trap speeds? Why were they not recorded? We would easily be able to tell which car is the fastest and which is simply traction limited with that data. Why is this constantly omitted by so many so-called journalists in so many so-called tests? What is so hard to understand?
Consider for a moment if the C63 S is outfitted with drag rubber. Does it suddenly become the fastest car there? The same goes for the M3. With proper rubber is it suddenly the fastest car? All this drag race shows the viewer is that the Alfa got the best launch which can vary greatly on street rubber and based on driver input.
If Carwow is not interested in properly displaying what the cars are capable of in the 1/4 mile then they should include trap speed data or run them from a roll where the traction variable is mitigated. That way this would actually be a useful comparison.
Fortunately, they do run them from a roll so this is not a total disaster. The Alfa Romeo pulls all three cars although the Mercedes-AMG looks to get a poor start. It certainly lends credence to the Alfa Romeo's tested 119.8 1/4 mile trap speed.
Overall, the Alfa Romeo Giulia Quadrifoglio is a very strong entry in the segment and that is a wonderful thing.
