Toyota Prius  (Source: wikimedia.org)
It will also show off its hydrogen fuel cell vehicle at the 2014 Consumer Electronics Show in Las Vegas

Toyota isn't messing around when it comes to green vehicles, and the automaker is further proving that with 15 new hybrids due by 2015, early specs for its next Prius and even a hydrogen fuel cell vehicle in the works. 

Toyota announced this week that it would unveil 15 new or redesigned hybrids globally with new powertrains that allow for lighter and more affordable vehicles. The lighter weight allows for greater fuel economy, and performance will also get a boost from enhanced electric motor, battery and gas engine technologies. 

But there's one hybrid in particular that Toyota favors: the Prius. According to the automaker, the next-generation Prius will have better batteries with higher energy density. The company said it's using nickel-metal hydride and lithium-ion where necessary and even upped its research on new battery technologies like solid state and lithium air as well as magnesium. 

The next Prius will also feature smaller electric motors; thermal efficiency of the gasoline engine will be boosted from 38.5 percent in current models to 40 percent in the next-generation; the use of Toyota New Global Architecture (TNGA) will allow for a lower center of gravity and increased structural rigidity, and better aerodynamics will offer an all-new exterior design.

Toyota will also create the next-generation Prius Plug-in (PHV) alongside the next-gen Prius. 

To top it all off, Toyota is working on its first commercially available hydrogen fuel cell vehicle It will be a mid-size four-door sedan, which will make its way to the Tokyo Motor Show in November.  That vehicle will also make an appearance in North America come January at the 2014 Consumer Electronics Show in Las Vegas.

“I would like to see us -- as an industry -- accomplish the same thing in the U.S.,” said Bob Carter, Toyota Motor Sales (TMS) Senior Vice President of Sales.  “That is…5 million hybrids, cumulatively, in the U.S. by close of business 2016.  That results in 3 billion gallons of gasoline saved, which is more than enough gas for the entire population of the United States to drive from San Francisco to Los Angeles in a Prius. It’s do-able. And I think we will do it.”

The Prius doesn't save you that much money. You're being misled by the MPG because it's the inverse of fuel consumption. High MPG means less fuel savings for a given improvement.

Your WRX STI is rated for about 21 MPG. If you drive 15,000 miles in a year, you'll burn 714 gallons.

The Prius is rated for 50 MPG. If you drive 15,000 miles in a year burning 300 gallons. Wow! You saved 414 gallons! Right?

Hold on. What if you got a car rated at an MPG right in between those two? 35.5 MPG. At 15,000 miles per year, you'd burn 422 gallons, or a savings of 292 gallons.

So:
21 -> 35.5 MPG (14.5 MPG improvement) = 292 gallon savings.
35.5 -> 50 MPG (14.5 MPG improvement) = 123 gallon savings.

292/123 = 2.38. The first 50% of MPG improvement saves you almost two and a half times as much fuel of the second 50%!

See what's going on? The higher the MPG gets, the less savings you get from each MPG gained. A car which "only" got 35.5 MPG would get you over 70% the fuel savings of the Prius (over the STI), even though its MPG rating represents half the improvement of the Prius.

Don't be misled by high MPG. The real number you want to look at if you want something proportional to money saved is 1/MPG.

All of your math may be correct but it still doesn't invalidate what the poster said.

STI to Prius 414 gallons annually=$1449 per year($120 per month)

35.5MPG car v Prius=$430 per year ($35 per month)

Even with the "misleading" 35.5 to 50 mpg upgrade, over 10 + years, we're talking more than $4k in savings. I don't feel like factoring in inflation but gas prices will be rising at least as fast as inflation I'm sure so it'll probably balance itself out.

Your scenario of buying a 35.5 car doesn't even fit the situation. He already has access to a 50mpg car so if he shifts his driving to that he will save a significant amount in fuel. Why would buying another car even enter the equation?

Who cares? Only an idiot compares an STI to a goddamn Prius. They aren't even in the same class.

Nobody buys an STI for fuel savings. I own two Imprezas, one an '05 STI. I thank the automotive gods that in this age of boring hybrids and family wagons cars like the Impreza even exists. Cut the mileage in half, I would still drive it everyday.

You're also forgetting to point out that the op probably saves a considerable amount of money in insurance as well. I have a 350Z and spent close to $3,000 in gas in 2012 alone (just commuting). I had my Prius 2 months short of 2 years, driven over 20k miles, road trip all over the place and spent a collective $1,700 in gas...in TWO years.

Let's not even start with insurance. I pay $2,400 a year to insure the Z. I pay only $750 a year to insure the Prius with much better coverage than the Z.

Yeah, the two cars are different class, yeah we get that the Prius is an eco car and the Z is a driver's car, yeah all the sh!t you Prius and hybrid haters love to regurgitate I've already heard -- but hey, if you want to talk figure and savings, might as well lay all the variables on the table.

In a year alone, I save over $5,000 in gas and insurance, driving the Prius and garaging the Z. Both cars are paid off, so car payment isn't even entered into the equation.

You are forgetting one very important bit here:

STI runs on premium gas (91 octane required) 12.6 (22) / 8.8 (32)

Prius runs on regular gas (87 octane) MPG: 3.7 (76) / 4.0 (71) (city / hwy -- liters/100km - imperial mpg in brackets)

when you factor in the gas grade requirement into the value of each the cost of running that STI jumps to well over double using the same amount of fuel.

Except you are using the combined highway/city numbers which does not apply to a lot of people.

I drive 95% city, most during heavy rush hour traffic, so a hybrid makes a huge difference in my mileage.

If I drove 95% highway, assuming it wasn’t all rush hour stop & go traffic, I'd seriously consider a diesel.

This is still a mostly free country, so you can drive whatever you want. For me it’s reliability, and good mileage at a reasonable cost that’s important, so I bought a Toyota hybrid (but not a Prius). I do like being able to go over a month between fill-ups.
