It's new TNGA platform will also allow for 20 percent less vehicle weight

Toyota Motor Corp. is shedding more light on the upcoming fourth-generation Toyota Prius, including a whole new design and at least an 8 percent gain in fuel economy. 
 
According to Automotive News, Toyota is looking to make some major changes in design, manufacturing and technology for the next Prius, which is due to be released in a year.
 
For starters, the next-gen Prius will be the first (or one of the first) Toyota vehicles based on the automaker's latest platform, "Toyota New Global Architecture" (TNGA). TNGA aims to improved engineering and low-cost as well as flexible manufacturing. 
 
This platform will call for a major redesign of the Prius' looks. TNGA means lower-slung vehicles with a more planted stance and lower center of gravity, which should improve handling and offer a sportier look.


One possible design direction for the next generation Prius -- the FT-Bh concept
 
Chris Hostetter, Toyota's vice president for strategic planning in the U.S., has said that the Prius could use a new look. 
 
"There's an undercurrent among most people that they're ready for a new Prius look," said Hostetter. "Maybe our architecture has been a little bit similar for the last two generations."
 
The Prius, which was first launched in Japan in 1997 and the U.S. in 2000, had an exterior design that was altered from Toyota's Yaris sedan. The second-generation Prius was released in 2003, and it received the raked hood and windshield. From 2003 to 2004, Prius sales increased dramatically from 43,162 to 125,742. Toyota is likely hoping to do the same with a completely redesigned fourth-generation Prius. 
 
Aside from design, the new Prius is getting a makeover under the hood. Its new ultra-efficient gasoline engine will achieve thermal efficiency rates above 40 percent, which is a nice boost from 38.5 percent in the current Prius. 
 
Toyota also talked batteries in its latest Prius revelations. It’s deciding whether to use lithium ion batteries for its fourth-generation Prius, or to offer some models with lithium ion and others with nickel-metal hydride batteries. While Toyota likes the power and energy performance of lithium ion, it worries about the cost compared to nickel-metal hydride batteries. 


Another possible avenue -- the NS4 concept
 
Satoshi Ogiso, managing officer in charge of global product planning at Toyota, said the automaker is pushing for at least an 8 percent improvement in fuel economy, which is slightly less than the 10 percent gains each Prius before it has received. 
 
"Generally speaking, hybrid powertrains are more mature than before. So, the general tendency is that when a technology matures, the improvement ratio is saturating, dropping," said Ogiso. "We will do our best effort to keep that pace."
 
But the fact that TNGA models will cut vehicle weight will be helpful. It was reported that Toyota should be able to cut overall vehicle weight by up to 20 percent on TNGA models, which includes the new Prius. 
 
Toyota mentioned lighter components, such as its new one-size-fits-all heating and air-conditioning unit that 20 percent smaller than the previous Prius generation's. 
 
Jonny Lieberman, senior features editor at Motor Trend, recently spoke with his sources at Toyota and shared a bit of secret info about the next Prius. Lieberman hinted that the next Prius would have a fuel economy rating of 60 mpg. This shouldn't be too hard to achieve assuming a lighter vehicle weight, more powerful electric motor, and a possible switch from NiMH to lithium-ion batteries.

"Fourth-Generation Prius: New Engine, New Design, More Fuel Efficient"

... and just as douchy as ever. Smug liberal idiots will still buy them, drive 52 mph in the left lane, and be convinced that they're saving mother earth. Yuck, no thanks.

Not really, at the price level and mileage rating people could be buying them as a budgeting issue.

Considering I own a Prius let me correct you: I got 7 in the left. And I get ~45-50ish MPG to boot.

Gas is going to go up again; $3.50/gal isn't going to hold, and anyone who thinks it so is kidding themselves.

Excluding light trucks and SUVs, hybrids/EVs are 7% of US car sales in 2013.

In Europe, 20% of Toyota's sales are hybrids, up from 12% in 2012:

That's not "hardly anyone".

Way to massage the numbers lol. 20% of Toyota sales being hybrids is FAR different than saying 20% of all EU auto sales are hybrids. So yes, as a whole, hardly anyone in the US and EU are buying hybrids.

Facts are facts, sorry. At this point in time I would expect to see at least a 25% total hybrid adoption rate, if everything you people say is true.

Unless less than 10% of something is a big deal in your book.

"You get a few more MPG than us...."

You sound like a complete lunatic with your "us vs. them" mentality. There's nothing "smug" about saving thousands of dollars on fuel every year. And it's not a "few more MPG". Compared to your average 30mpg all-motor car, it's more like 20mpg savings and compared to your average 15-20 mpg truck or SUV it's more like 30-40mpg. It's several thousands of dollars a year in savings for a lot of people. And the financial impact is compounded when gas prices go back up during the summer.

I have a 15-25mpg 420hp gas burner in the garage that I take out on the weekends. I used to take it out every day for a very short period but I quickly wised up and realized I was flushing my money down the toilet every weekday going to-and-from work on the same congested roads where the vehicle you drive is irrelevant. Ugly? Who cares!

Every time I've decide to take my sports car to work instead of my Prius, I always end up in the same old stop-and-go pattern and I always tell myself, "This miserable crawl is no-more and no-less enjoyable than in my Prius and I just spent $5 on fuel instead of my usual $1". The amount of money I save on gas every month covers 85% of the Prius monthly payment. This allows me to use both cars with hardly any discernible extra out-of-pocket expenses and the miles and depreciation (resale value) of my nicer car stays high. It's a complete win-win situation.

The only thing your bias is doing to you is hurting your checkbook. Good luck with that.

Buy whatever you want.

If you want an economical car, then a Prius makes rational sense. If you want a luxury car, then a BMW makes rational sense. I think that's the point being made...

Those smug liberal idiots will laugh all the way to the bank while you keep shoveling your money as fast as you can into Exxon pockets.

Very true. Hardly anyone wants to admit just where all the things they use come from.

People want to trash talk the petroleum industry then turn around and refuse to wear any leather or wool clothing because it harms the little animals while wearing cloths made of polyester, nylon and rubber, all of which come from petroleum. The only way to avoid using petroleum would be to live as people did in the 1700s, and not many want to do that.

You again. You seem to have a judgmental chip on your shoulder.

The people I know who have a Prius are conservative Asians who want to save money on gas. They are not smug, nor liberal, nor do they drive 52 in the fast lane unless stuck in LA traffic. They did not pick a car to try to save the planet but if the money saved via fuel economy is better for the environment, that's a bonus.
