Hybrids Cars a simple Idea
This document provides an overview of hybrid vehicles. It discusses that a hybrid uses both an internal combustion engine and an electric motor powered by batteries. It describes the different levels of hybrids from full to mild and the basic components. It also outlines the different types of hybrids including series, parallel, and series-parallel hybrids. The document discusses maintenance considerations and battery lifespan for hybrids. It addresses common questions around safety, submersion, and performance of electric vehicles. Finally, it provides pros and cons of owning a hybrid vehicle compared to a regular vehicle.

- 18. ALL ELECTRIC VEHICLEPERFORMANCE Speeds range from 25-90+ mph Distances per charge range from 25-250 miles Equivalent mileages @ $4.00/gal gas: • Cars 100-200 mpg • Motorcycles 200-400 mpg Considerably less maintenance/complexity • No fluids, muffler, water pump, oil, belts, starter • Longer life brakes (regen), less heat degradation • No stops at gas station or oil changes, starts in winter, fewer places to pay bills (home electric bill) 18
- 19. ADVANTAGES DISADVANTAGES Better mileage Improved acceleration (most of the time) Less dependence on fossil fuels Lower emissions Some states provide incentives for driving a hybrid Great driving experience Little highway mileage increase High initial cost Needs high fuel cost to be worthwhile Could cost more to repair Extra maintenance items Some hybrids need special tires HYBRID VEHICLE VS REGULAR VEHICLE 19
