At the present time we don't have a specific project on heavy trucks, but quite a number of our researchers do a great deal of work with the truck industry.
A good deal of the work of the diesel engine researcher at Windsor I mentioned earlier is funded by International Truck and Engine. There's a great deal of crossover between heavy trucks and light vehicles as well in diesel, and also in hybrid technologies and so on.
The heavy truck industry is quite different from the auto industry per se because of the size of the production runs--5,000 trucks is a lot of trucks, 5,000 cars is three days' production. It's peanuts. So it's not a complete match, but I expect we will be doing some work with the heavy truck industry in the coming years.
