Hybrid Electric Vehicles - Technology Evolution and Experience with Brazilian Gasolines E25 2010-01-1442

Due to worldwide concern regarding greenhouse gases emission, mainly CO₂, automakers are developing new technologies to reduce vehicles' fuel consumption. One of the most promising technologies, growing fast in USA, Japan and Europe is the Hybrid Electric Vehicles (HEVs).
In the Brazilian Market, HEVs availability is still absent, which causes uncertainties about possible impacts caused by the introduction of this new vehicle technology in the big cities. However, as requirements of non-pollutant technologies arise, HEVs are expected to be available in Brazilian Market in the next years. Within this scenario, in 2002, aiming to evaluate the adequacy of Brazilian Gasolines blended with up to 25% v/v of Ethanol in HEV technology, Petrobras Research and Development Center (CENPES) purchased from USA a 2002 Toyota Prius and a 2002 Honda Insight. Since then, both HEVs are being tested at CENPES's Vehicle Test Laboratory (LEV).
This paper will present topics related to HEV technology evolution, future trends, governmental benefits offered for these vehicles in some countries. Additionally, noticeable advantages and disadvantages of this technology in the world market are highlighted. It will also present CENPES experience with HEVs, including the methodology evolution required for laboratory tests with HEVs and the preliminary emission and fuel economy test results obtained with Brazilian Super Premium Gasoline - less than 30 ppm of Sulfur content - blended with 25% v/v of Ethanol in a 2002 Toyota Prius and a 2002 Honda Insight HEVs.
