Stellantis Heritage has unveiled the Abarth Classiche 500 Record Monza '58, a one-of-a-kind creation based on a '70 Fiat 500.

The vehicle was built to celebrate the 100th anniversary of Monza Circuit, the world's third-oldest motor racing track. This delightful little gem was inspired by the work of Carlo Abarth, who, in 1958, shattered six records at Monza in Abarth's first-ever tuned 500.

As such, the recreation sports green paintwork is similar to the hue on the record-breaking original. An extra set of lights have been fitted to the front end - along with an Abarth grille and badging - while the bumpers have been removed. On the front and side, you'll note the red "Fiat 500 Abarth" decals. The rear-quarter panel boasts "Record Monza" badging.

There are a few subtle differences between the recreation and the original vehicle. The restomod, based upon a later model, has larger taillights and conventional front-hinged doors. The '58 500, however, is equipped with suicide doors, smaller rear light clusters, and stands taller than the replica.

It's not only visual changes that have been made. The two-cylinder engine has been tuned, with displacement increased to 595 cc thanks to the Abarth Classiche 595 Tuning Kit. The company says this is inspired by the original kit offered by Abarth in the sixties.

No mention of performance is made, but we're guessing the figures are comparable to Abarth's original car, which was tuned to produce 26 horsepower, enough for a top speed of 73 mph.

Inside, you'll find the interior also pays tribute to the original vehicle. The cream-colored door trim and the single racing seat - another nod to the original - have been trimmed in a light cream upholstery that features contrast stitching. An elegant wooden steering wheel and Jaeger dials dominate the dashboard and add a touch of class to the otherwise austere cabin.

Other motorsport-inspired changes include a solid roof (it replaces the factory-fitted soft top) and bare floors.

The unique specimen was displayed next to the original record-breaking example at the Milan AutoClassica show this past weekend, along with the newly-revealed Abarth Classiche 1000 SP sports car.

Based on the now-defunct Alfa-Romeo 4C, the 1000 SP is limited to just five units, and the company says there's just one left.

One would think the reproduction 500 Abarth would be relegated to a museum or heritage fleet, but no. The car will be sold and should prove to be a special piece for any Fiat collector. Perhaps the lucky buyer will snag both the final 1000 SP and this one-of-one recreation.

Abarth is going through somewhat of a revolution, and it will soon embrace the world of electrification. Its first all-electric model, the 500 EV, leaked last week and it looks pretty incredible. We'll know more about the new Abarth when it debuts on November 22.

Elsewhere, Fiat's local lineup is poised for growth. The aging 500X may soon gain a new stablemate in the form of the new 500e, which was recently teased for North America.
