OEM Strategies for Passenger Vehicle Engine Downsizing in Western Europe
Frost & Sullivan, May 2010, Pages: 73
Automotive original equipment manufacturers (OEMs) in Europe are now facing the challenge of reducing CO2 emission from cars apart from the Euro norms. Apart from emission reduction measures such as hybridisation and using all-electric powertrains, engine downsizing has gained momentum and has proved to be the most cost-efficient method to reduce tailpipe CO2 emissions. OEMs face several challenges in developing downsized engines such as overcoming the loss of power. This study analyses the engine downsizing (reduction in engine displacement) trends in the Western European automotive market. This study also analyses the various powertrain trends of OEMs in Europe.
This Frost & Sullivan research service titled OEM Strategies for Passenger Vehicle Engine Downsizing in Western Europe provides an overview of the engine downsizing trends in the European passenger vehicle market. This research service also analyses the future market shares of different engine displacement ranges for original equipment manufacturers (OEMs) in Europe. In this research, Frost & Sullivan's expert analysts thoroughly examine the following technologies: engine downsizing and engine boosting.
Engine Downsizing Gets a Boost, as Stringent Emission Norms in the European Automotive Market Step-up the Demand for Engines with Low Carbon Dioxide Emissions
Engine downsizing implies reducing the cubic capacity of an engine without hampering its performance. In the European automotive market, this is driven by the carbon dioxide (CO2) emission norms that are expected to come into effect in 2012. The capability of OEMs to deliver fuel-efficient and affordable engines with low CO2 emissions will be the key success factor for participants in this market. “The most important factors for the increasing trend towards downsizing engines in the European automotive market are the strict limits on tailpipe emissions from cars coupled with greater end-consumer awareness towards cleaner and greener vehicles,” says the analyst of this research. “The limit on CO2 emission from cars, starting 2012, will further boost the drive towards smaller engines.”
Taxes based on bands of CO2 emissions will lead to hefty sums of money being paid for cars with high CO2 emissions. It results in a situation where the demand for low CO2-emitting models from end consumers will witness a steep rise. This trend is already seen in several markets within Europe and is likely to gain momentum over the next 3-4 years. End-consumer preference towards cars with low CO2 emissions is expected to increase the penetration of engines with small displacements. More than 50 per cent of gasoline engines are anticipated to have displacements lower than 1,400cc by 2016. The shift towards smaller engines will also result in significant growth of gasoline engine turbochargers.
Vehicle Manufacturers to Focus on Developing Efficient and Low CO2-emitting Engines
Although downsizing of engines is considered one of the most cost-effective methods to reduce tailpipe emissions, the development and boosting technologies involved in these engines do not reduce the cost of powertrain. Furthermore, controlling the specific load in diesel engines is a challenge. Downsizing also results in lower power output from the engine, which, in turn, reduces the low-end torque, and the need for improvement in transient response arises. “Higher specific load leads to greater nitrogen oxide (NOx) emissions – a concern for Euro 6 compliance,” explains the analyst. “This high emission of NOx due to downsizing is likely to be a challenge for diesel engines.”
Diesel engines have witnessed significant downsizing in the last 6-7 years. Further downsizing could be limited due to issues pertaining to specific loads on engines. Instead, improving the efficiency and promoting ‘clean diesel’ technologies will be the key focus. Gasoline engines too are anticipated to witness a trend similar to that of diesel engines. Hence, vehicle manufacturers should focus on developing efficient and low CO2-emitting engines.
