Spinning Your Wheels: Here's Why Dyno Results Are Incomplete and Useless

The release of the Civic Type R has created a lot of buzz. The recent media launch generated plenty of opinions as to its performance, including some reviewers who believe Honda has underrated the CTR in the same manner it has done with the Accord V6 in the past.

Their speculation seemed to be proven true as a video released from a shop in Puerto Rico showed the car making 301 wheel horsepower. Many outlets reported on the dyno test and, while some showed the data with a little skepticism thrown in, others went all in and told us that the CTR has hidden horsepower.

The real truth behind the dyno test is that it is valueless. We do not have any data on its calibration or the weather, and the dyno operator could have applied any correction factor on the data to boost the results. This is not an isolated case in reporting sketchy dyno results, as I see it multiple times per month from various outlets and, in just about every case, the data and reporting are meaningless.

Because they are not being aggressively invested in and because the government is pushing EV, which are far worse than any other vehicles on the road, it’s clear the push to EVs has nothing to do with the environment.
