2018 Fiat Spider Abarth vs. Mazda Miata RF Track Day Comparison - The Surprise Winner

This past week, Torque News had the opportunity to run the 2018 Fiat 124 Spider Abarth and the Mazda Miata RF back to back on the track at the beautiful Monticello Motor Club in New York State. MMC is one of the finest road courses in the Eastern United States and perfect for a comparison between these fun and capable track-worthy roadsters. Both were stick shifts and they even had similar paint. It was a fair fight and we aren't going to be wishy-washy about which was more fun to drive on that given day.

Fiat 124 Spider Abarth and the Mazda Miata RF - Engine & Transmission
The biggest difference between these two cars on-road is the engine and transmission. Both have their merits, but on-road I would pick the Miata every time. I love the way the Miata engine is linear from 900 RPM to redline. The dull spots in the Fiat's turbocharged engine just don't feel right in a roadster.

Despite the slight power advantage, the Miata is also quicker than the Fiat 124 Spider Abarth on public back roads, where acceleration past 60 MPH is really never going to happen. However, on-track one starts out with an aggressive launch and never sees low RPMs again until the time on the track is over. Here, the 124 Spider Abarth's turbo is not a disadvantage. In fact, the meatier mid-range torque means that if one chooses, one can skip a shift here and there compared to the Miata. I'd have to give the Spider Abarth the edge in terms of on-track engine response and performance.

Fiat 124 Spider Abarth and the Mazda Miata RF - Handling
The fanbase and motor press often say that the Fiat 124 Spider has less body roll than the Miata. I honestly don't care. The Miata's roll, and its up and down action are some of the things I love about the car. If I want a flat-handler I'll buy a Mini. No, I won't really, who wants a front wheel drive sports car? Still, they do feel different.

I've tracked the 124 Abarth twice now on different days and both times it slid around the track a lot. It was easy to make the car slide sideways and it is an easy car to oversteer with the throttle. This by comparison to the Miata, which feels more planted in corners. The Miata may well be a bit quicker in corners due to this, but I don't care. I want a track day car to be fun first and quick second. The 124 Spider Abarth is more fun because it is a car I can break loose easier. Advantage Spider.

Fiat 124 Spider Abarth and the Mazda Miata RF - Conclusion
My choice for the better track-day car is the Fiat 124 Spider Abarth. Not because it is a few clicks quicker on a stopwatch, but because I enjoy driving it more. So, for me, having tested both on track and having also had both cars for a full week of on-road testing, the 124 Spider Abarth is a more fun track-day car and the Miata RF is the more fun on-road car.

Post-script - For the record, Car and Driver's instrument testing confirms my opinion that the Miata is quicker on-road and the Fiat 124 Spider Abarth quicker on track.
