, previously known as Calsonic Kansei Corporation, is a global automotive parts supplier headquartered in Japan, operating 58 production facilities across regions including the United States, European Union, South Korea, Mexico, Thailand, South Africa, India, China, and Malaysia.
The enterprise originated in 2000 through the consolidation of Calsonic Corp., which specialized in air conditioning systems and heat exchangers, with the instrument panel manufacturer Kansei Corp.. In January 2005, Nissan boosted its shareholding from 27.6% to 41.7%. Later, in November 2016, Nissan declared its intention to divest its shares to the American private equity firm Kohlberg Kravis Roberts (KKR), which completed full acquisition by February 2017.
In early 2019, Calsonic Kansei combined operations with auto component producer Magneti Marelli, purchased by KKR from Fiat Chrysler Automobiles for €6.2 billion, resulting in the creation of the consolidated Marelli brand.
History
The origins of Calsonic trace back to August 25, 1938, when it was established as Nihon Radiator Manufacturing Company, Ltd., initially manufacturing radiators. The company’s inaugural president was Nagao Gentaro. It adopted the name Nihon Radiator Company in 1952. In April 1954, Nissan Motor acquired a majority stake of 60% to ensure a steady radiator supply. That same year marked the expansion into producing mufflers, followed by the introduction of automotive heaters in 1955.
The "Calsonic" brand was introduced in 1976 when Nihon Radiator launched its first overseas facility in California. The name blends "California" with "sonic," representing swift development. By 1988, coinciding with its 50th anniversary, the company officially adopted the Calsonic Corporation name.
Founded on October 25, 1956, Kansei Corp. began as Kanto Seiki Company, Ltd., a spin-off from Nissan focused on manufacturing instrument clusters. In 1960, Kansei moved its headquarters and production plant to Saitama City.
On April 1, 2000, the merger of Calsonic and Kansei resulted in the formation of Calsonic Kansei. Nissan further increased its stake from 27.6% to 41.7% in January 2005.
On November 22, 2016, American private equity firm KKR & Co. reached an agreement to acquire Calsonic Kansei for $4.5 billion, targeting growth beyond Japan’s contracting market. The acquisition was finalized by March 23, 2017.
On October 22, 2018, Calsonic Kansei revealed plans to merge with components manufacturer Magneti Marelli from Fiat Chrysler Automobiles (FCA), which KKR had acquired for $7.1 billion (€6.2 billion). Contrary to press reports suggesting a direct purchase by Calsonic Kansei, the deal was conducted between KKR and FCA. FCA initially rejected a $5.9 billion bid. By May 2019, the merged company adopted the Marelli name to enhance global market presence.
On June 7, 2025, Marelli Holdings indicated it might seek Chapter 11 bankruptcy protection in the United States. Subsequently, on June 11, 2025, Marelli officially filed for Chapter 11 to reorganize its debts and pursue new ownership opportunities.
