MPG COMPARISONS: When traveling the same distance, what would save more fuel -- improving the fuel efficiency of Vehicle A from 8 miles per gallon to 10, or improving the fuel efficiency of Vehicle B from 25 mpg to 50? Surprisingly, the answer is that Vehicle A saves more gas. Over the course of 100 miles, Vehicle A uses 12.5 gallons of gas at 8 mpg, and 10 gallons at 10 mpg, a savings of 2.5 gallons. Vehicle B would use 4 gallons of gas at 25 mpg, and 2 gallons of gas at 50 mpg, a savings of just 2 gallons. Although driving a vehicle that uses the least gas is the optimum situation in terms of emissions and cost, this example highlights the way small improvements in mileage can add up to savings for the trucking industry.

WHAT IS CAD: A computer-aided design system combines hardware and software to enable the user to design everything from furniture to cars and airplanes. The user can view a design from any angle and zoom in or out for close-up or long-distance views. CAD systems typically rely on a combination of a keyboard and conventional mouse to control what's on the screen.
