The 2008 Toyota Prius was given a very good reception during its release — rating one of the top green cars. The only challenge for the 2009 model is whether it can surpass its predecessor.

But that would barely be a question since Toyota is on a mission for the 2009 Prius to: drive the economy ratings skyward, and cut the associated costs by 20-30 percent.

Shocked by the news that Honda is lowering the price for the Fit Hybrid for 2008 with the price differential just 200,000 yen (some $1,700) more than the regular gasoline version, Toyota is planning to slash R&D costs and halve its current hybrid differential of 500,000 yen (some $4,240) to compete.

Sources say the next Prius will also be able to run longer and faster in pure electric mode, up to a sustained 30 mph, which will significantly extend its zero-emissions range.

The current model is hitting North America at present. So, what more if the 2009 version will be released with better economy and value?
