The Fiat 500e (project 332), also known as the 500 elettrica or New 500 is a hybrid or battery-electric car by Italian manufacturer Fiat as the third generation of its 500 city cars, following the original 500 (1957–1975) and second-generation 500 (2007–2024). The third-generation 500e is manufactured at the Mirafiori plant in Turin, Italy, starting in 2020, and was sold alongside the second-generation 500, which was manufactured in Tychy, Poland until 2024. It was scheduled to be launched at the Geneva Motor Show but that event was canceled due to the COVID-19 pandemic; it was launched on 4 March 2020 in Milan.

The 500e has a 320 km (199 mi) range on the European WLTP combined test cycle, and achieves 400 km (249 mi) on that test's urban cycle, which is generally favourable toward electric vehicles (EVs). Most versions of the car are powered by an 87 kW (117 hp) electric traction motor, fed by a 42 kWh lithium-ion battery pack.

Previously, FCA had assembled a different model, also named the 500e, from December 2012 to June 2019 at its Toluca Car Assembly plant in Mexico; this earlier 500e was a BEV derived from the second-generation 2007 Fiat 500 and was sold exclusively in a limited number of states within the United States market.

Sergio Marchionne called for FCA to pivot towards electric and hybrid automobiles starting in 2018, including an all-new electric 500e by 2020. FCA showed the Fiat Centoventi concept at the Geneva Motor Show in March 2019; the Centoventi concept previewed what automotive industry believed to be a future BEV version of the Fiat Panda, which in turn was expected to form the basis for the next electric Fiat 500e. The concept Centoventi showcased a modular battery concept, allowing an extended range using dealer-installed battery packs.

In July 2019, FCA announced plans to invest €700 million in its Mirafiori plant to build a new production line devoted to its first BEV marketed in Europe, tentatively named the 500 BEV, with production to start in the second quarter of 2020. The new line was planned to have an annual production capacity of 80,000 500 BEVs. FCA invested another €50 million to build a battery production line at Mirafiori in October 2019. Camouflaged prototypes of the third-generation 500 BEV were photographed while undergoing tests in December 2019.

The public unveiling amid the COVID-19 pandemic on 4 March 2020, previously scheduled for Geneva, was led by FCA Chief Marketing Officer Olivier François, who said they held the event in Milan "to show that FCA stands close to Milan and to Italy." The 500e sits on a totally new platform and is slightly bigger than the second-generation model, which was introduced in 2007. Compared to the second-generation 500, the third-generation 500e is 60 mm (2.4 in) longer, 60 mm (2.4 in) wider, and 40 mm (1.6 in) taller, with a 20 mm (0.79 in) increase in wheelbase. The older, second-generation 500 (2007) is equipped with an internal-combustion engine or a mild hybrid drivetrain and remained in production until 2024.

A variant of the third-generation 500e, fitted with the mild hybrid drivetrain from the second-generation 500, will be sold as the 500 Ibrida starting in early 2026. It will be assembled alongside the 500e at Mirafiori.

Initially, the 500e was available exclusively as a two-door cabriolet four-seater in the La Prima trimline, with production limited to 500 examples per country. Before any local incentives, the La Prima launch editions have a retail price of €37,900 in Italy. La Prima was available in one of three colours: Mineral Grey, Ocean Green, and Celestial Blue, designed to be reminiscent of the earth, sea, and sky, respectively; the soft top was finished with an exclusive monogram logo.
