The Cost of Fuel Economy in the Indian Passenger Vehicle Market

Large animals have a much better fuel economy than small ones, both when they rest and when they run. At rest, each gram of tissue of the largest land animal, the African elephant, consumes metabolic energy at 1/20 the rate of a mouse; using existing allometric relationships, we calculate that it should be able to carry 1 g of its tissue (or a load) for 1 km at 1/40 the cost for a mouse. These relationships between energetics and size are so consistent that they have been characterized as biological laws. The elephant has massive legs and lumbers along awkwardly, suggesting that it might expend more energy to move about than other animals. We find, however, that its energetic cost of locomotion is predicted remarkably well by the allometric relationships and is the lowest recorded for any living land animal.

Vehicle Market

A number of studies revealed that the role of women both as influencer and independent decision-maker is becoming increasingly important in the buying decision involving the purchase of a passenger vehicle. In today's highly competitive South-African motor vehicle market it is becoming vital that motor manufacturers pay greater attention to market needs - specially with regard to important market segments. This study analyses certain aspects of the market segment consisting of women. The null-hypothesis this study tested was that there are no differences between male and female consumers pertaining to the relative importance of evaluation criteria, when purchasing a passenger vehicle. By means of analysis of variance it was established that there are significant differences (P0,01) between men and women with regard to 15 of the 65 evaluation criteria. It was also found that there are 50 insignificant differences between the two groups. The hypothesis, as formulated is thus rejected, with regard to 15 of the evaluation criteria, in favour of the alternate hypothesis.

Policy Simulations

Exploiting a rich dataset of passenger vehicle registrations in 20 US MSAs from 1997 to 2005, we examine the effects of gasoline prices on the automotive fleet's composition. We find that high gasoline prices affect fleet fuel economy through two channels: shifting new auto purchases towards more fuel-efficient vehicles, and speeding the scrappage of older, less fuel-efficient used vehicles. Policy simulations suggest that a 10 percent increase in gasoline prices from 2005 levels will generate a 0.22 percent increase in fleet fuel economy in the short run and a 2.04 percent increase in the long run.

This article reviews the use of the electric car around town, and save gas and short-trip abuse to gasoline-powered mainframe. With gasoline so cheap, making the case for CNG vehicles and home filling is difficult based on economics alone. A person would have to log quite a few natural gas miles before he would have recovered the cost of the home fueling station. Engineers seeing the big picture on the hydrogen economy know that hydrogen has to be made, generally either by electrolyzing water or reforming hydrocarbons. Most of the time, that will mean burning coal or natural gas to produce the electricity needed for electrolyzing water—or reforming natural gas. Natural gas with home refilling makes better sense for daily commuting. Use of an alternative fuel vehicle rewards the choice with a waiver for a single-occupant vehicle to ride in the HOV lanes. Plug-in hybrids can double fuel economy in city and highway cycles operating solely in the gasoline-sustaining mode. Trips made on batteries alone are, of course, pure EV allies. Plug-in hybrids remain experimental.

The Impact

Increasing governmental fuel economy requirements drives automakers to increase the fuel economy of their fleets. One of the methods for improving fuel economy is lightweighting vehicles through the use of materials with high strength to weight ratios. Some of these new metals entering the automotive sector are difficult to machine and cause drastically reduced tool life and increase machining cost. It has been shown that electricity has the ability to reduce cutting force during orthogonal cutting and turning. In this research, a design of experiments study on an electrically assisted drilling operation is conducted to determine the impact and interaction between the following input parameters: applied electric current, feedrate, spindle speed, and number of holes cut. These variables used to determine impact and interaction on the following output variables: flank wear, axial cutting force, and temperature evolution. A 2D finite volume method model is used to predict drilling temperature during the process, and is used to aid in predicting axial force. It is found that electric current can reduce cutting force by 10% for 1008 steel at the cost of increased temperature, however, arcing at initial contact causes increased tool wear at higher current inputs.
