2015 Toyota Prius to be lighter, more fuel efficient

 2015 Toyota Prius to be lighter, more fuel efficient
2012 Toyota Prius - 19.9.2011

Tires will play a key roll

The Toyota Prius started its life as an ugly little hybrid, but that quickly changed with the introduction of the second- and third-generation model. Now, new details are starting to emerge about the fourth-generation model which is expected to be launched in 2015.

According to Inside Line, the car will feature lightweight materials, improved aerodynamic styling and specially-designed tires that have an extremely low-rolling resistance. The tires are seen as critical, since engineers have identified them as a key area where fuel efficiency gains can be made.

It remains unclear how much can be done to boost the car's mechanical efficiency, but the current model is rated at 51 mpg city / 48 mpg (US).

Toyota has to significantly improve the interior plastics used in this car. Feels like you're sitting in a $10k car. Thus IMO a Avalon Hybrid would be better.

The Prius, like any other hybrid, is a stepping stone in the right direction to all electric vehicles. Sorry guys, but ICEs are history. Give it another 20 years, and gasoline engines will be a novelty.

How different from this can it look? It don't think it will be much different. I like the philosophi from japanese car makers that normally aspirated engines are more reliable, but since the engine in this isn't used that much, why put a 1.8L in it?

U get the same consumption from bigger diesel engines, Prius has become a social status, look at me am green and care about the environment. Instead of regulating auto industry they have to regulate the birth rate, with 7 billion humans who will become 9 billions by 2050 our planet is doomed anyway so let us enjoy our cars

My guess is that the 2015 Prius will look almost the same as the current Gen III model, but with switch to a new generation of dry-electrode lithium-ion batteries so the gasoline engine runs even less. In short, 60+ mpg average based on the EPA 2008 test may be within reach.

I think it was in Gen II that they talked about LiON for Gen III (mumble, mumble, re-tweak). I wonder if there is any hope of that for Gen IV.
