Qualitative Testing.

Auto – journalism is almost 100 percent qualitative research. Most of what the field is revolves around it primarily in test drives, interviews, and event coverage. This week I will be referencing a test done by www.insideline.com. They took two competitive cars and tested them on the Dyno, a machine that is used to record horsepower, top speed, and torque curves.

If you’re a car enthusiast who loves to drive but doesn’t want to spend over 30,000 you know about the Volkswagen GTI and the Mazdaspeed 3, and the rivalry they have that could run deeper than that of the Red Sox and Yankees. There’s the GTI, the iconic hot hatch that started it all rated at 200 horsepower and then the new kid on the block Mazdaspeed with 263 horsepower. What inside line wanted to find out is which car has the better power curve. Its understood that the Mazda makes more power and is faster, but its engine be able to perform as smoothly as the GTI’s?

The answer is no, the dyno recorded that the GTI built up power progressively low in its rev range and built almost until redline before power would slowly diminish. The Mazda on the other hand had less low end power and had an immediate power drop well before it’s redline.
