Diesel vehicles have always had a competitive edge over their petrol counterparts in their performance over long haul journeys, eating up motorways and A-roads alike. But most importantly for company cars and fleet vehicle directors it is the more efficient mpg and the government's emissions tax regime which has always had diesel preferred over petrol engines.
In light of the VW emissions scandal in September there has been a shift in demand from consumers from diesel to petrol engines. Manufacturers have taken note of this and have been stepping back in future development of diesel vehicles.
Demand for VW's was down 14% in Germany, VW's home.
Traditionally diesel vehicles have needed turbo boosted engines to match petrol engines as they lack in torque but make it back up in power. But there is now a growing trend of turbo fitted engines finding their way into petrol vehicles; the end result being petrol engines that offer greater fuel efficiency and reduced emissions. Furthermore, a small turbo boosted petrol engine can now match the output a larger regular petrol engine vehicle.
The recent Paris Climate Conference highlighted the need to reduce emissions and has also set new targets for countries to reduce or limit their output of greenhouse gases in the future. The UK government already has a tax initiative in place to charge more polluting cars greater than 'cleaner' engine vehicles. With the growth of smaller sized vehicles with turbo engines the result will be increased demand from fleet operators and consumers alike, as well as lower emissions from vehicles in the future.
Honeywell, a leading turbo manufacturer with 34 percent share of the global market, has had great success in redesigning turbo chargers to increase their efficiency and also to reduce their size to fit smaller vehicles. By 2018, Honeywell predicts that in Europe more than two thirds of new light vehicles will be fitted with turbo engines and in China the market for turbo fitted engines will more than double.
“Consumers in all regions expect performance and fuel economy, and are rapidly switching to turbocharged vehicles. Honeywell continues to develop its worldwide engineering and manufacturing presence to help our customers handle the complexity of global launches. We are building in added flexibility and responsiveness to customer needs through application of the Honeywell User Experience which informs the way we make all our products easier to install, use and maintain.” Peter Hill, Honeywell Transportation Systems VP Marketing and Product Management.
