After a week of driving the 2010 Toyota Prius, we got into it one morning to find the gas gauge only showing one little digital bar. But a quick check of the range showed we could go another 45 miles, which is what the Prius is all about. At a consistent 50 mpg in real-world driving, this car sips gas. Toyota made a few improvements to the cabin tech, as well, but we were left wanting more, as other companies have raised the bar quite high.
