Nissan provided flights from Washington, DC, to Santa Barbara, California, and accommodation so Ars could drive the Rogue Hybrid. Ars does not accept paid editorial content. Nissan has a new version of its best-selling Rogue SUV, and it’s launching the model here with the latest version of its e-Power hybrid system, which Ars tested back in February. Most of the hybrid cars you can buy today are parallel hybrids, which means that they have an internal combustion engine and an electric motor, both of which drive some or all of the wheels—everything works in parallel. But there’s another approach. Instead of connecting the engine to the wheels via a transmission, it can act as a generator and charge the traction battery, which in turn powers the electric motor. Since the engine and motor work in series, this is known as a series hybrid.
