For whatever reason, you always hear about electric vehicles. You hear about fuel cells, because it's all about flavour of the month, but it's been the flavour of the last couple of decades.
There will be electric vehicles and there will be fuel-cell vehicles, but the guts of our economy are still the reciprocating engine. There has been a lot of movement in technology for that system. Jeff mentioned types of fuelling systems. There have been other things, such as on-board computer diagnostics, that drive efficiency. I used to do my own engine maintenance; I don't go near it now, because I need a computer to do so. It's a very high-technology piece of equipment.
I'll give an example on the lightweighting aspect. People think about lightweighting in terms of the vehicle body, but they're wrong. The engine block is a big chunk of metal, and it's very heavy, as anybody who has ever lifted an engine can tell you. How do we use aluminum as an engine block? That's some of the research we are doing at the moment. How do you make aluminum into a lightweight engine block?
There is a lot of internal combustion engine research going on. There are new cycles of reciprocating engines coming out every day. Part of it is testing. There are some great labs in Canada. Jeff has some, and I have some. There are industry labs. Ford has a major engine lab in Windsor. It has 12 of the best test cells you will ever see, and it's in our own back garden. There is a lot of innovation, and I think there's still—pun intended—a lot of mileage in research on internal combustion engines.
