Electric vehicle (EV): A vehicle powered by an electric motor that draws power from a battery.43. Hybrid electric vehicle (HEV): A vehicle that combines an internal combustion engine with an electric motor and battery to improve fuel efficiency.44. Plug-in hybrid electric vehicle (PHEV): A hybrid vehicle that can be plugged in to an external power source to recharge the battery.45. Fuel cell vehicle (FCV): A vehicle powered by a fuel cell that generates electricity from hydrogen and oxygen.

Glossary for Car Enthusiasts

46. Apex: The ideal point on a corner where a vehicle should be positioned for optimal cornering speed.47. Camber: The angle of the wheel in relation to the ground, as viewed from the front or rear.48. Caster: The angle of the steering axis in relation to the vertical, as viewed from the side.49.
