By March 23, 2017, KKR officially completed the tender offer for Calsonic Kansei. On October 22, 2018, Calsonic Kansei announced that it would be merged with components manufacturer Magneti Marelli from Fiat Chrysler Automobiles (FCA), acquired by the parent fund KKR for $7.1 billion (€6.2 billion). The news was mostly wrongly reported by the press as Calsonic Kansei purchasing Magneti Marelli, while the transaction happened between KKR and FCA. The company's previous bid of nearly $5.9 billion was deemed too low by FCA. By May 2019, Calsonic Kansei and Magneti Marelli united under one brand name, Marelli, as part of its strategy to compete on a global scale. Calsonic Kansei is primarily associated with Kazuyoshi Hoshino's Impul racing team in Japan, sponsoring them as Calsonic since 1982 as a title sponsor. By 2016, Calsonic Kansei is the longest-running title sponsor of a motor sports team in the world. On March 9, 2016, Formula One racing team McLaren announced a multi-year partnership with Calsonic Kansei. Calsonic is also the official radiator cooling supplier for Scuderia Toro Rosso since 2007.
