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.

  • Fred I had a 2009 S-line mine was chipped but otherwise stock. I still say it was the best "new" car I ever had. I wanted to get the new A3, but it was too expensive, didn't come with a hatch and no manual.

  • W Conrad I'd gladly get an EV, but I can't even afford anything close to a new car right now. No doubt if EV's get more affordable more people will be buying them. It is a shame so many are stuck in their old ways with ICE vehicles. I realize EV's still have some use cases that don't work, but for many people they would work just fine with a slightly altered mindset.
  • Master Baiter There are plenty of affordable EVs--in China where they make all the batteries. Tesla is the only auto maker with a reasonably coherent strategy involving manufacturing their own cells in the United States. Tesla's problem now is I think they've run out of customers willing to put up with their goofy ergonomics to have a nice drive train.
