Myth Busted: Mile-High Test of Mazda Miata vs. Turbo Fiat 124 Spider Abarth Disproves Turbo Advantage
The Mazda Miata and Fiat Spider are built from many of the same components on the same production line by the same workers. However, there are key differences and the engine and transmissions are the biggest two things that set these vehicles apart from one another. Although the Fiat 124 Spider Abarth has more peak power, 164 hp vs. the Miata's 155 hp, it is almost a second slower in the sprint from 0-60 MPH. Many enthusiasts prefer a normally aspirated roadster, but more power is always welcome, as long as comes with an advantage.
One advantage some turbo fans have pointed to is "power at elevation." The idea is that an engine with a built-in compressor will retain more of its usable power in the mountains, or anywhere above sea level. The theory goes that since the air is thinner, and since the turbocharger compresses the air, the turbo will do better. A new test by The Fast Lane Car (TFL Car) has just debunked that myth.
The publication tested two Miata trims vs. the 124 Spider Abarth. What makes the test interesting is that it was done at just under a one-mile elevation in Dacono Colorado. Would the Spider Abarth's turbocharger give it the extra advantage at this elevation? Not according to the runs the publication made. The Abarth was beaten by both the Miata Club and also the Miata Grand Touring. As the top of page image shows, the approximately one-second advantage the Miata has proven to have in prior tests closer to sea level holds at over 5,000 feet.
The group also timed the cars around the racetrack.Would the turbo have an advantage in that scenario? You will have to watch the video to find out. We aren't going to spoil this good story by TFL Cars.
