Zack Spencer has been on Television for many years now starting out as a weatherman!. Currently hosting the car rating show. Cars are changing so rapidly now with the new technology. The price of oil is going up and Ottawa has just signed an agreement with Washington to set the same standards for across the border. All car manufacturers will be required to have an average fleet gas milage of 42 MPG. That's an average! That's amazing. So you will see electric and other fuels being offered just to get the average up as that has to include the commercial vehicles for delivery etc. This all has to be achieved in just one model away in just 6 years time. No one meets that target today.
 
The most famous Hybrid car on the road today is the Prious but the Camry out sells it. You will see many more models offering a Diesel option. 50% of all passenger cars sold in Europe today are the modern Diesels. Many manufactures offer a Hybrid car today. Even racing cars are using electric engines to boost their performance for better acceleration. Hybrids do cost more and you can expect to see prices go up $3,000 to $5,000 per vehicle. Disels do get better milage by 20 to 30 percent. 8 litres per 100 km. for a big vehicle is acceptable. This is clean diesel with little soot. To achieve this they have a heat exchanger in the exhaust system that traps the soot them burns it off. Like a self cleaning oven. Soon we will see plug in Hybrids that can charge off household current. http://en.wikipedia.org/wiki/Fisker_Karma There are other ways to save gas. Take the bus. Even once a week will help. A car with a gas powered generator to generate electricity for an electric car. Buy the most fuel efficient car you can for your use.
