The Nissan X-Trail's e-POWER system is a different way of doing hybrid technology. The e-POWER system is different from conventional hybrids, which can have the gasoline engine directly drive the wheels; the e-POWER system uses the engine only to produce electricity for the electric motors that power the vehicle. The setup promises EV like driving experience with the convenience of a gasoline engine for charging. But the issue of whether this complicated system has any real advantage over conventional hybrids in terms of fuel efficiency, performance or long term reliability is up for debate. The smooth, instant torque raves some drivers, but others wonder if the benefits are worth the potential hassle of a newer, unproven technology.
