Under the hood of vehicles like the Civic Hybrid and Prelude, the e:HEV powertrain primarily operates as a series hybrid: the 2.0-liter Atkinson-cycle gas engine drives a generator, which feeds electricity to an electric traction motor driving the front wheels. There are no actual physical gears or gearboxes.  S+ Shift is an advanced evolution of Honda's previous Linear Shift Control, using software algorithms to mimic an 8-speed dual-clutch transmission. #honda #civic
