Hybrids have a long history that goes back to 1901 with Ferdinand Porsche's Loehner-Porsche "Mixte." However, it wasn’t until the 1990s that the technology gained traction, fueled by the launch of the original Prius. Most hybrids have gas engines but some from Mercedes use diesels. Peugeot was the first to introduce a mass-produced diesel hybrid in 2012. After Kia's liquified petroleum gas (LPG) hybrid, here comes Fiat's ethanol hybrid in Brazil.
