Toyota is reportedly trying to ensure a 10 percent improvement in fuel economy

Toyota’s Prius is the world’s best-selling hybrid — the company announced around this time last year that over 3 million Prii had been sold since its introduction. In the United States alone, the Prius, Prius c, and Prius v dominate the hybrid sales charts despite new competition.
 
When it comes to the fourth generation Prius (and its variants), Toyota wants to get things right the first time around. As a result, the company is delaying the next Prius by six months. So instead of production kicking off in spring 2015, it has been pushed back to December 2015. A plug-in version of the new Prius will follow nearly a year later in October 2016.
 
Although specific reasons for the delay have not officially revealed by Toyota, it is reported that efforts are being made to ensure that the new Prius provides at least a 10 percent boost in fuel economy compared to the third generation model.


2014 Toyota Prius
 
According to Satoshi Ogiso, chief engineer for the Prius, the next generation vehicle will showcase a new modular vehicle architecture (similar in concept to Volkswagen MQB efforts) and of course, a brand new hybrid system which is said to be lighter and more powerful.
 
If the new Prius does indeed feature a 10 percent improvement in fuel economy, it would have a combined (city/highway) EPA rating in the mid 50s. This figure is something that today’s most efficient gasoline engine-only vehicles can’t touch in the U.S. market. Although it’s been hinted that the vehicle would hit 60 mpg, that appears to be a pipedream at this point.

60 MPG

That might almost be worth the ugly looks. Oh and before the folks from the EU show up, you can't compare EU and US EPA mileage figures because of differing testing methodologies, not to mention the difference in EU and US gallons.

there are no gallons in Europe.

Also my country is not in the EU but the car tests and stuff are the same as in the rest of Europe.
This means you have not preempted my stupid comment: omg dailytech I want it in litres/100km, MPG is a meaningless number to me.

Yes there are gallons in Europe (UK is part of Europe is it not?) and yes people make these stupid comments in EVERY fuel economy thread (that's why I'm posting this). The point is you cannot compare US fuel economy to EU/UK/whatever fuel economy, period.

No, UK is not a real part of Europe even though its close.
UK and Europe are so different in every way that i would say that US and Europe are more similar than UK and Europe. UK is more like Japan.

what makes the most sense is to use km per liter(KPL). I can easily figure out how far I can go multiplying how many liters of gas I have left by KPL. l/100km just make things too complicated.

l/100km can be confusing as hell when the numbers get too small. A 50% improvement would barely move the numbers making it hard for some people to grasp the change.

L/100km, helps ppl truly understand better how the mileage really is. A old truck that got 13 mpg and get a new one at 26 mpg. Just doubled your mileage. But it doesn't "seem" like much. Get a car 30 mpg to 60 mpg, "seems" better as the numbers are bigger and I still doubled my mileage.

Truck, 13 mpg(7.6 gal/100mile), 26 mpg(3.8 gal/100mile). A 3.8 gallon savings.

Car, 30 mpg(3.3 gal/100mile), 60 mpg(1.6 gal/100mile). A 1.7 gallon savings.

Mpg can be misleading on the true gas savings of going up in mileage.

Simple, just do the conversion. It's relatively painless...

50 MPG equates to

21.257 km/l
4.7043 l/100 km

Doesn't account for the differences in EPA vs everyone elses test methods. I did mention that too. Again, the idiots just skip over that.

why won't they just move to diesel already? that would be 65-70MPG

diesel doesn't make a very efficient hybrid drivetrain. they can't run a miller-cycle combustion and constant start-stop is incredibly hard on them. i would also assume the stop-start cycle is pretty harsh.

there's a reason you don't see any production diesel hybrids. i know Volvo, VW and Mercedes have prototypes but basically the reviews are not positive, especially on the MPG's.

diesels have pretty bad cold-weather performance, so that eliminates much of the country. there are 15 states where you will need to use an engine block heater in the winter seasons or your engine wont even turn over. i had this problem in my SVT Focus (not a diesel) just because the starter couldn't fight the high compression + cold oil in the winter. fortunately the vehicle came standard with an engine block heater in most northern states or where sold with a winter package.

then take into account diesel engines, at least in the united states, are ruined by emissions regulations. if you want a diesel, a non-hybrid is "good enough" for decent MPG's, but you will pay for it in overhead maintenance and cost-of-entry (diesel cars, on average, are $5000 more than unleaded models, meaning it takes a few years just to break even.)

i get above 50mpg in my car now (last mark 3-4 1.3D turbo punto, best car i have ever had) for a car that is £15k-£20k compared to £5k-8k (new) £1k-2k old

the car properly makes more emissions when its been made (Toyta)

Eh, you can get 40mpg's from non hybrid cars now.

Of course, you don't really buy a car as a mode of transportation, you are buying pride to impress people you know and those you don't know. A superficially ugly vehicle such as the Prius could never gather as much attention as a muscle car.

Yet the ugly Prius outsells every muscle car on the market.

Most people (at least adults) buy cars to get from point A to point B, not to over compensate for their inferiority feelings.

I don't find the Prius ugly. Most sports cars look like cheap Walmart sneakers, imo.

All cars make statements, with plus and minus perceptions for each type. Driving a muscle car doesn't make a good first impression universally any more than a green car a negative impression universally.

Yep, could really care less what the car looks like as long as its fun to drive and I can walk away from a crash. Everything else is secondary, as long as the price is within reason.

I think many people just have to make sure their car doesn't look bad. Then, after that point anything goes. 10+year cost-to-own and safety are top at my list of priorities too.

"60 MPG - That might almost be worth the ugly looks."

Not sure what you mean by that. The difference in savings, both fuel and dollars, between 50 mpg and 60 mpg is miniscule.


The move to Lithium Ion

From what I have read I believe the 4th gen Prius will make the jump to a Lithium Ion battery instead of a NiCd battery.

They've pretty much hit the limit of what they can get out of a regular hybrid. Even adding a larger battery and stronger motors isn't going to increase the mileage much.
Notice that they are talking 55mpg, only a 10% improvement.

They need to start producing more plug-in Hybrid, even if they only have a short 15-20 mile range. That would cover some peoples entire commute and trips to the store.

Plug-in operation requires a far more powerful motor and battery though. The base hybrid-system is generally only capable of electric assist and low speed cruising (not accelerating). Toyota's hybrid popularity has been due to a design that balanced more on price and reliability than what is cutting edge. Would I like to see lower priced plug-ins, definitely, but for the moment the cost is still too high.

its not a Honda (engine always running the electric motors help the engine) the Toyta car is the other way round under 29mph the engine helps the electric motors when needed (unless you floor it then full power kicks in form both)

the engine will try stop as well if your under 29mph and do not need power for battery's yet (there is a EV button as well that will try its best to Only use the electric motors think it can do 50 miles in EV mode before the engine kicks in below 29mph, but quite sure the engine still must be running above 29mph but its idling just for electrical power unless you floor it then it auto ignores EV mode and full power happens, engine+electric)

under 10mph it tries its best to Not use the engine at all unless you floor it then both will power the drive at the same time (most emissions are under 10mph when pulling away or in stop start traffic),the car is Perfect for London as it avoids the congestion charge as well witch is nice that alone will pay for it self in the first year alone (no road TAX as well as its under 95-100 emissions)

it can pull away just on the electric motors alone

this is why the Prius can only Ever be an full automatic car as well as it Prefers the electric motors over the engine (it be a lot harder to control the power in an Manuel due to the engine stopping), in the Honda Hybrid just treat the electric motor as a Turbo but powered by a electric motor (i think this is how most Hybrids works apart from the Prius)

the Honda comes in Manuel as well but that's due to the Engine always runs, it probably has auto stop and start when your not moving, but to just move just a bit forward the engine will start soon as you put your foot on the clutch

Don't confuse NiCd (Nickel-Cadmium) with NiMh (Nickel-Metal-Hydride) batteries. NiCd is ancient technology never used in the Prius.
The 4th gen Prius is going to have several enhancements (more lightweight body, smaller but more powerful and more efficient drivetrain, ...etc) not just battery chemistry change.
