Owners of the company’s plug-in hybrids aren’t bothering to charge their electrified sportscars, according to CarExpert. The revelation was made during a launch event for the 849 Testarossa earlier this month in Spain. The same data showed the automaker that its customers rarely use the eManettino setting it has developed to allow them to take advantage of the plug-in hybrid technology in its cars. The 849 Testarossa, like other plug-in hybrid Prancing Horses, features four modes: eDrive, Hybrid, Performance, and Qualifying. Click here to see more photos of Ferrari’s plug-in hybrid models.
