Heavy Vehicles Hybrid and Electric Trainer
When we think about the future of our planet the development and production of vehicles equipped with hybrid drives is a logical and necessary step. Lower emissions and less fuel consumption are benchmarks for future generations of modern automobiles. Such measures ensure that the fundamentals necessary for life are sustained while quality of life improves. Hybrid motor vehicles and electric cars are not just a future consideration, but in fact the auto industry has already made them available on the market. The only rational diagnostic strategy available for these vehicles presupposes the necessary system understanding.
