A new comparison of the Mazda Miata with its lower-power normally aspirated engine vs. the higher power turbocharged Fiat 124 Spider Abarth counters the idea that turbos are better at altitude.
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.
