I imagine that a majority of my blog readers are unlikely to be submitting an order for this racing variant of Mazda’s N platform, since Abarth is advertising to sell them for around $175,000 USD (plus a bunch of taxes), but I’ve been motivated today by Peter T. (owner of the ABARTH 124 GT discussed in an earlier article), to learn more about the ABARTH 124 RALLY, which has already won the FIA R-GT World Championships for 2017 & 2018!
I am now presenting a compilation of the specs and observations I’ve gathered thus far (updated as I become aware of changes/corrections) …
ABARTH 124 RALLY ~ GENERAL INFORMATION
Body Style: Coupe (removable hardtop only; no soft top installed)
Platform: 4th generation of N platform developed under Mazda/FCA joint partnership
Assembly Plant(s): Hiroshima, Japan (partial build) and finished up in Turin, Italy
Drivetrain: Front-midship engine, rear wheel drive (RWD)
Intended Use: Not certified street legal; turnkey race car built to FIA R-GT specifications.
Here’s the FIA release (the same group governing Formula 1) on the new R-GT Cup. Full R-Gran Turismo class rules are here, but the short version is two doors, two wheel drive, naturally aspirated or turbocharged or supercharged, no limit on engine size (though larger engine does mean higher minimum weight), must be a production car with at least 200 road models built per year, and must have a trunk of at least 2.65 cu ft (no Zonda R’s). So it’s open to all kinds of sports car / Gran Turismo car insanity.

Curb Weight*, pounds (kg): 2,315 (1,050) (vs. 2,516 (1,141) for AT Abarth 124 Spider)
Weight Distribution: 49% Front / 51% Rear (vs. 53% Front / 47% Rear for 124 Spider)
“Passport” Weight: curb weight + weight of spare wheel(s) and other options for race
* North American Curb Weight is defined as the weight of a vehicle in running order, unoccupied and unladen, with all fluid reservoirs filled to nominal capacity (full) including fuel, and with all standard equipment fitted (options and accessories are not included).
Fiat claims the ABARTH 124 RALLY empty weight is 2,205 pounds, but after subtracting 95 pounds of fuel (11.9 U.S. gallons), 15 pounds remain unaccounted for. I’m going to assume one spare wheel is standard equipment, has been included in curb weight, but has been subtracted for the empty weight figure.
