We already have had a chance to get behind the wheel in our 2010 Honda Insight review and we've already done a design dissection of the 2010 Toyota Prius, we haven't yet seen how the two stack up against each other. For starters, it's difficult to make this comparison as neither automaker's released full specs yet. However, we're still able to make some initial observations and in cases where we don't have all the details, we've tried to provide some good guesstimates.
Price: In both cars' cases, we're waiting on price. It's rumored the Insight will retail for $18,500 while the current Prius goes for $22,000. The new one is larger, has a bigger engine and fancier technology. Will it cost more money? Advantage: Insight.
Size: The Insight is and entry-level vehicle, the Prius a mid-size. While the Insight is noticeably smaller, there's less difference once you're inside than you'd think. Nearly the same space in a smaller package? Advantage: Insight.
"Fun" Factor: Neither of these cars is going to drive like a Lotus Exige, but, believe it or not, the Insight is actually kind of fun and rewarding. We haven't driven the 2010 Prius, but "fun to drive" is hardly a hallmark of Toyota's current range. Advantage: Insight.
Fuel Economy: The Prius kills the Insight dead in estimated EPA fuel economy numbers, returning 50 MPG combined to the Honda's 41 combined. Since both are estimates, we wouldn't be surprised to see one or both of the cars rise or fall by a MPG or two when they're officially certified. Advantage: Prius.
Just for fun, we've put together a chart to walk through all the salient details between the two "green" machines. We've also tossed in some other putatively green competitors — the Ford Fusion Hybrid and the 2009 VW Jetta TDI.
