The Prius' chief engineer, Akihiko Otsuka, drove a 33-mile route in and around Napa and averaged 62.9 mpg. During the drive week, he levied a Beat-The-Chief challenge to anyone who wanted to take him on. AutoblogGreen was able to get the in-dash display to read in the mid- to low-70s for most of the route, but the last ten miles on a busy 55-mph road dropped that to 64.5 mpg. Not bad, but only good for a standing near the absolute bottom of the rankings among other journalists. Overall, the best score was 94.6 mpg, although that involved some less-than-real-world driving behaviors and conditions. The best "honest" score was 75.3 mpg. In all, about half of the journalists were able to get over 70 mpg, while the rest, save two, were able to get more than 66 mpg.Increased fuel economy is one of many ways the 2010 Prius has evolved, but the driving experience is similar to the last generation. Despite a slightly longer wheelbase, wider track and new low-rolling resistance tires, you don't notice any serious changes from the driver's seat. The front MacPherson struts and improved body rigidity keep the ride smooth around town and on the highway. Overall, it's the same commuter-friendly conveyance you'd expect and, thankfully, rearward visibility is vastly improved over the outgoing model.However, one small change we did notice was the absence of that infernal beeping when the car is shifted into Reverse that plagued the outgoing model. After asking Otsuka about the change, we were told that the pre-production models we were testing had the feature removed, but when the production model goes on sale, the beep will return. The good news? Otsuka said dealers can turn off the sound at the customer's request.Speaking of current Prius owners, the automaker is convinced they'll trade up. In fact, Toyota's Bob Carter said the company expects 20-25 percent of third-generation Prius sales will be repeat buyers. So where will the other 80-85 percent come from? It's clear there's a hybrid sales fight brewing between Toyota and Honda , and Toyota needs to convince buyers that paying a few thousand dollars more for the Prius over the new Honda Insight is worth it.The Insight , which starts at $20,470 , is smaller and has fewer features than the Prius, but it's obviously a direct competitor. Based purely on aerodynamics, the Prius beats the Insight (0.25 versus 0.28 Cd). Honda was understandably proud of its "world-leading coefficient" number when the Insight was announced earlier this year , but Toyota has clearly bested its Japanese rival in this department. Does it matter? The Insight is a fun drive that won't attack your wallet at the pump or its point of purchase, while the Prius gets better mileage, is larger and comes with a cache of green cred that would fill the Grand Canyon Throw in the new 2010 Ford Fusion Hybrid , which is even larger and starts at $27,270 , and 2009 is shaping up to be a good year for potential hybrid owners. With plug-in vehicles supposedly coming in 2010 (and pure electric vehicles not long after) and the poor economy, all bets are off on which hybrid will come out on top. Still, Toyota polled current Prius owners and 90% said their next car will be a Prius. The automaker wanted to offer these repeat buyers some upgraded technology, so it has included two new features on the 2010 Prius: Lane Keep Assist and Intelligent Parking Assist.Lane Keep Assist (LKA) is triggered by pressing a steering wheel-mounted button that turns on the Lane Departure Warning system. The system looks for yellow and white lines on the pavement and lets the driver know if he or she starts to leave the lane. Lane Keep Assist is used in conjunction with the Prius' Dynamic Cruise Control, but it won't drive for you. The system knows if you let go of the wheel and using a turn signal will disengage LKA entirely.Another fancy feature is Intelligent Parking Assist (IPA), which makes quick work of parallel parking. When pulling up to an available parking spot, you push a button above the driver's right knee to activate a sensor that can see where parked cars are sitting. When the system finishes its calculations , the rear-view camera turns on and displays a grid that estimates the intended parking position. If the grid is correct, the driver presses "OK" and then the system takes over. From this point, all the driver does is control the speed of the car using the brake pedal. If the driver takes his or her foot off of the brake pedal, IPA will shut down when it reaches its speed threshold. As smart as the new Prius is, however, it's not smart enough to know if a person suddenly appears in the designated parking spot. We were able to test IPA, and it works as advertised . Both LKA and IPA are available as part of the 2010 Prius' Advanced Technology Package (pricing TBD).
