"…We believe that there can be continuous improvements to internal combustion engines. One way that we stand out as somewhat different is that we will continue to develop diesel engines, and we think they will play a role in the future. But also gasoline engines will have a lot of improvements; we are on the pathway to direct injection, downsizing and turbo charging as well, and also improvements in transmission technology as well as the overall vehicle. Moving on from that we think there will be increased hybridization and also pure battery-electric vehicles."
