Hybrid Synergy Drive (HSD), also known as Toyota Hybrid System II, is the brand name of Toyota Motor Corporation for the hybrid car drive train technology used in vehicles with the Toyota and Lexus marques. First introduced on the Prius, the technology is an option on several other Toyota and Lexus vehicles and has been adapted for the electric drive system of the hydrogen-powered Mirai, and for a plug-in hybrid version of the Prius. Previously, Toyota also licensed its HSD technology to Nissan for use in its Nissan Altima Hybrid. Its parts supplier Aisin offers similar hybrid transmissions to other car companies.

The Toyota Camry is an automobile sold internationally by the Japanese auto manufacturer Toyota since 1982, spanning multiple generations. Originally compact in size (narrow-body), the Camry has grown since the 1990s to fit the mid-size classification (wide-body)—although the two widths co-existed in that decade. Since the release of the wide-bodied versions, Camry has been extolled by Toyota as the firm's second "world car" after the Corolla. As of 2022, the Camry is positioned above the Corolla and below the Avalon or Crown in several markets.
