Because a truck is typically 1) heavier, 2) less aerodynamic, 3) has lower gear ratios (to better pull/haul a load), and 4) they don't *have* to get good mileage - Federal CAFE standards don't apply to most trucks
I hate it when people pull a bunch of random nonsense out of their A** trying to sound smart. CAFE Standards as of 2007 apply to all vehicles under 10000lbs GVWR sold in The United States of America and the new CAFE standards that are going to apply to model years 2012-2017 are going to be even worse.
Yes, diesel trucks generally get much better gas mileage than regular gas trucks. They even sometimes get better gas mileage than hybrid trucks.
yes trucks are better than because cars you can do a lot more with a truck than you can with cars
They don't. Diesels get better mileage and last longer.
sometimes
Since motorcycles normally get better mileage than cars/trucks, I would think it's obvious that the demand for them increases.
Compared to cars, pickup trucks get bad gas mileage. However, if you can find a hybrid or especially fuel-efficient model of truck (for example, Ford trucks tend to be slightly more fuel efficient than Toyota trucks) you may be able to get good gas mileage.
Newer cars are geared towards being more fuel efficient than older cars. Cars made in 2012, depending on engine size, will likely get much better gas mileage than your 1993 Buick. These older cars were geared more towards comfort and power and less towards improved gas mileage.
Ford trucks are usually worse than other makes when comparing gas mileage. Brands like Toyota and Mazda are better.
Probably not
There are many reasons why hybrid cars are better than regular cars. One reason is that hybrid cars get better gas mileage than regular vehicles. Another reason is that hybrid cars help protect the environment.
Bicycles give you more gas mileage.
Hybrid cars have substantially lower exhaust emissions than normal cars and are better for the environment. Hybrid cars of all types get much better mileage per gallon of gas than normal cars.
