Edmunds test drives the new Prius

Toyota is just now finally getting some stiff competition in the hybrid market after holding on to the "High MPG Crown" for quite some time. On the lower end, the Prius is being assaulted by Honda's relatively affordable second generation Insight which starts below $20,000. That vehicle is rated at 40 MPG/43 MPG (city/highway).

On the other end of the spectrum, Ford's $27,270 Fusion Hybrid brings more conventional styling to the table and a vastly improved driving experience compared to the appliance-like Prius. In addition, the Fusion Hybrid still manages to maintain EPA ratings of 41 MPG/36 MPG (city/highway), although Autoblog editors were able to extract 43 MPG combined from their test vehicle.

With the stakes in the hybrid market getting higher, Toyota is ready to dazzle with its third-generation Prius. We first got a glimpse of the new model back in mid-October and the Toyota official announced the new Prius at the Detroit Auto Show in early January. Now, Edmunds has gotten a chance to fully track test the model ahead of its scheduled rollout for American consumers.

First and foremost, Toyota should be able to consolidate costs a bit with the new Prius as it no longer rides on its own platform. Instead, the vehicle is based on the current MC platform that underpins the Toyota Corolla, Matrix, and Scion xB -- presumably, the MC platform will also be used for the upcoming Lexus HS 250h hybrid sedan.

Toyota also addressed both power and NVH (noise, vibration, and harshness) with the upgrade to a larger 1.8-liter four-cylinder engine (up from the 1.5-liter unit used in the previous model). The new engine not only allowed Toyota to improve the Prius' acceleration and increase fuel economy, but it also reduces the cacophony inside the cabin when the gasoline engine is running.

Other improvements include a smoother ride, more natural steering and brake feel, and an even more advanced set of features and options. The Prius can now be equipped with such features as solar panels on the roof to power the A/C system and a self-parking system for those that either can't be bothered with or are inept at parallel parking.

Most importantly, the new Prius definitely puts up impressive numbers when it comes to fuel economy. The new vehicle is rated a 50 MPG combined (city + highway). However, Edmunds was able to achieve 52.2 MPG combined during 115 miles of driving with 60% weighted towards highway miles. Edmunds figures that the numbers would creep up a few more MPG if the percentages were reversed seeing as how the Prius excels in around town situations where the electric motor can handle more of the propulsion duties.

Toyota hasn't yet announced pricing for its third-generation Prius, but expect the new vehicle's base price to hover around or slightly higher than the current $22,000.

Updated 3/25/2009
Autoblog's road test of the 2010 Prius shows that the vehicle is capable of much more than just 52.2 MPG:

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.

That is completely backwards. There is not 100% regeneration efficiency, it takes more power to speed up and slow down continually, MUCH more even if braking recaptures some. Coasting, or rolling without power input regenerates nothing, that would be a constant drag causing even more power loss due to higher engine duty cycle.

Perhaps what you meant was they suffer less fuel economy loss in city driving than ICE counter products, but they all get much better MPG when "there is one very - continuous drain on the battery", running at a constant speed without speeding up or slowing down, so long as that speed isn't excessively high.
