In 2004, Toyota launched a hybrid car: Prius. The principle of this car is the addition of an electric motor to the traditional petrol engine. The objective is to request the electric motor with starting and low speed and to request the petrol engine at higher speeds. The goal of this technology is to decrease the fuel consumption (economy of money) and thus to decrease the greenhouse gas' emissions. The report is this one: the profit in consumption is not significant compared to an equivalent car using a diesel engine. The development of this technology has a real impact on the purchase price of the car. Indeed, according to tariff grids' of the current market, the recourse to hybrid technology involves a rising of prices of sale from approximately 20%. This additional cost is not negligible because a non-hybrid car is already a significant investment. French PSA automotive group (Peugeot/Citröen) decided to adapt this technology to a diesel engine to obtain a significant gain in consumption and to have a really ecological car.
[...] When: Now for a launch in 2 years Where: in France How: Ad hoc survey There are 2 types of descriptive research: longitudinal (panel data) and cross sectional (sample surveys) . We don't need to have an overview of behaviour evolution (use of panel data). That's why we decided to carry out a cross-sectional analysis. As we wish, the cross-sectional method aims to categorize people. Here we need to collect primary data by selecting a representative sample of the population through the use of a questionnaire. [...]
[...] The short duration of the questionnaire can also represent a disadvantage Self administrated The questionnaire is filled by the respondent himself. There are several methods: mail, fax, magazines and internet. E-mail is a not expensive method but the response rate is very low such as fax. Mail can be used to provide an anonymous side which is not useful for in our questionnaire Interview The most important advantage is the clarification that the interviewer can brought. The researcher is assured that the responses are provided by the right person. [...]
[...] 3. Who is the family's member, which is more implied in the decision of purchase of your car? 4. What is the model? 5. Unleaded or diesel? 6. Do you know what a hybrid engine is? The hybrid diesel engine is a new engine, which combines 2 energies: diesel and electricity. The performance of these vehicles marks a significant breakthrough in terms of fuel consumption and greenhouse gas emissions. These results go hand-in-hand with improved driveability during [...]
