Toyota wraps up 3-year Strasbourg Prius PHV demo project; average 46% reduction in fuel consumption compared to gasoline ICE vehicles

Toyota Motor Corporation (TMC) has completed its three-year plug-in hybrid vehicle (PHV) demonstration project jointly carried out with Électricité de France (EDF) and the City and the Urban Community of Strasbourg in France.

The partners revealed the final conclusions collected from this large-scale demonstration, in which approximately 70 units of the Prius PHV were provided to Strasbourg. Data was accumulated by utilizing the 145 dedicated charging stations installed in the city by EDF to identify vehicles and exchange information. The vehicles travelled more than a total of 4 million kilometers (2.485 million miles) during the project. Among the findings were:

  • The plug-ins achieved an average 46% reduction in fuel consumption compared to conventional gasoline vehicle of similar size with an average charging frequency of 1.1 times a day.

  • A direct correlation between the recharging frequency and fuel consumption: higher charging frequency leads to lower fuel consumption.

    For example, Toyota said, take a user that recharges 1.6 times a day. While driving 40% in hybrid mode and 60% in electric mode, the user obtains levels of approximately 70% of reduction in fuel consumption compared to a conventional gasoline vehicle of similar size. This represents an estimated saving of €1,400 (US$1,800) on an annual basis, assuming that the car drives around 20,000 km (12,400 miles) a year.

  • 60% of the recharges are carried out at work and 37% at home. Public charging points are welcomed by users for supplementary charging. Scheduled charging leads to CO2 emissions reductions of 10% to 15%.

  • Average cost of recharge is around €0.30 (US$0.40) (all costs included).

  • Up to 61% of CO2 emissions can be reduced compared to conventional gasoline cars of similar size.

Thanks to the participation from the citizens of Strasbourg, Toyota was able to acquire valuable data for the further promotion of PHV technologies. Based on the results that were obtained from this demonstration project, we intend to offer technologies more accessible for widespread adoption.

Toyota launched the Prius Plug-in in Japan at the beginning of 2012, followed by introductions in North America and Europe. To date, around 31,100 plug-ins have been sold, equivalent to 1.5 times the number of Prius sold in a full year when launched in 2000. For Europe, the year-to-date figure amounts to 4,417 units, with sales starting only end of summer 2012.

EDF, with the support of its subsidiary Electricité de Strasbourg (ES group), incorporated innovative features into the charging infrastructure put in place for the project. One of these features automatically shifts vehicle charging time to off-peak period, benefiting from reduced power costs. In addition, an internet based monitoring service enabled users to verify that the average cost of a recharge did not exceed €0.30.

To make the system even more customer friendly, EDF and its subsidiary, Sodetrel, developed a smartphone application to geolocate charging points and check their availability.

The Urban Community of Strasbourg is now moving forward to engage in the cross border program CROME (Cross Border Mobility for Electric Vehicle). New outlets meeting European standards for electric vehicles have been installed, some allowing full charge of an electric vehicle within two hours. Both users of electric and plug-in hybrid vehicles will benefit from these new charging points.



More: Stable prices allow people time to adapt but quick change force hasty adaptions. Every $10 increase in the price of a barrel of crude represents a transfer equivalent to around 0.5 per cent of global income from oil consumers to oil producers but global GDP is actually constrained by less than that because oil producers will spend some of their windfall so a $10 rise in the oil price reduces global GDP only by about 0.2 per cent.

This year oil prices did rise by about $12 in just two months between early December and early February and this was sufficient to knock around 0.25 per cent from global GDP.

“EV motors are less expensive than 20% efficient ICE”

Of course there is no BEV even close in price to a similar car. I am interested in the whole car.

“as shown in study after study ”

This study talks about how much you can save on energy not mentioning what the initial cost is and what the pay back period.. Toyota would not leave out that information if it would help sell their cars.

“The EV advantage gets greater with every passing year. ”

So go buy one, tell us how it turns out.


I find it very entertaining that the very same people who usually rant about the externalities of nuclear power are prepared to drop all of their objections if a (manufacturer-sponsored) study shows that nuclear electricity can be cost-competitive with gasoline.

Let's not extrapolate these numbers too much. The study is specific to France, where the grid is predominantly nuclear and (arguably) taxpayer-subsidized, and gasoline is heavily taxed. The numbers don't work the same in most countries.


In 1973 oil was $3/barrel and the minimum wage $1.25/hour.

Oil prices went up over 33 TIMES. The US minimum wage - which most workers start at, which once fed young people, families, and even helped pay college tuition - went up ONLY SIX(6) TIMES.

The lower 80% of Americans, odds are that is YOU AND I, own less than 7% - NOT EVEN ONE TENTH OF AN HONEST AMERICAN WEALTH DISTRIBUTION.

But kp feels everything is just hunky dory. Over $12.2 BILLION TOTALLY wasted on Hanford nuclear waste cleanup and NOTHING cleaned of lethal radioactivity in seventy years of polluting the US northwest.

The reactor power outputs and weapons outputs a total waste now being disassembled - for further dozens of times earth overkill nuclear weapons.

Major plant/construction financial decisions are calculated into the tenths of a percent through decades.

When 75 percent of all nuclear plants AVERAGE 307% of the contracted construction/maintenance price - the only way for a utility to avoid bankruptcy is to up the rates and CHEAT THE CUSTOMER as many times as the monopoly decides and bribes.

EVs, wind, and solar dampen and threaten the oil/coal/nuclear/energy gouging monopoly with just the EXISTENCE of a personal transportation/energy alternative - besides the economic fact that distributed alternative energy already costs less than the aging utility overruns in MANY COUNTRIES and less than ~all "full impact" total fossil fuel costs.


If EVs are the answer, then we would expect millions of people to buy them. If new nuclear designs are so horrible, then we should expect China to implode. What happens when China creates Gen IV reactors then prospers with abundant, affordable and clean power while we still scorn those as "horrible"?

“polluting the US northwest ”

Not so much. Lived in North Richland (as close as you can get to Hanford) for thirteen years and it certainly not the least bit polluted. Go back every year to visit our son who still lives there. We plant to retire there if we are lucky enough.

It is a great place to raise kids. Many times we rode out bikes down to the river to go swimming.

No lethal radiation.

“$12.2 BILLION TOTALLY wasted on Hanford nuclear waste cleanup ”

This project is is to turn waste from making weapons into glass for long term storage in a geological repository. It is not a project for clean up Hanford most of that has already been done.

If you live in Richland you get used to rhetoric from people who do not live there and have no concept about the place. It goes like this. There is a terrible problem, the government is not spending enough money. Followed by the government is wasting too much money.

“But kp feels everything is just hunky dory. ”

let me list some of the things that I would call better than when I was a young sailor.

We have stopped building nuclear weapons
We are using the weapons material to make power
Nuke plants are economically producing 20% of our power
Money has been set aside from the production of power to cover the cost of dismantling nuke plant
Nuke plants will run for many years after paying for the cost of construction providing value to the customers
and my favorite, we are designing new nuke plants and building them.

I really like the last one because I get paid to do it.

“I find it very entertaining ”

So Bernard it sounds like you have not heard of Kelly harbor freight PV panels to charge the batteries on a electric bike?


@kelly your comments about the price of EV's getting cheaper is worng. There are several studies been done that show People assume that since Electronics get cheaper that EV's will get cheaper
Electronics get cheaper because you can stuff more into the little space. Batteries are chemical the same size fits all so until someone comes up with a totally different kind of battery or discovers an new chemical that no one knew existed (maybe dark matter)


and so is my spelling


How many $trillion dollar nuclear damages and cleanups will it take to admit it's not worth it?


@danschl, power electronics/systems improvements alone made the 2013 Leaf EV 15% cheaper and longer charge ranged in just 2 years.

Li-ion batteries are over 4 times more powerful than lead-acid in volume, and improving - without dark matter..


Thanks Kit P for being the perfect set up man for all the good points made in the other comments. I assume that was your intent, because if not, you should consider altering your approach. Or, just continue to supply the needed starting point for someone else to make a good point, it works for me.


@kp, at different times, you've referred to Hanford, WA as a 'paradise' and a 'desert'(on the Columbia River?) - depending on your argument needs.

There are a 150 million ebikes, besides EVs, on world roads and my $200 solar system provides over 6,000 miles of ebike charge annually(or $200 in nuclear cost overruns).

Roger Pham

If you followed the price trend in Lithium batteries, you would have seen major drop in prices: 4 folds in about 6-8 years. 6 yrs ago, a pack of LiPo battery 2.2 Ah 11.1 V 10-15C cost $60, now, a much higher quality battery of 25C of same Ah and Voltage costs about $15. If you have to replace batteries for cell phone or camera, you will see the same trend. A camera Li-ion battery used to cost $30, now costs about $8-10.

The prices of subsequent generations of Prius have declined, though not as fast as a 4-fold decline, but if you just isolate the cost of the electrical components only, then you would see a sharper decline, even though the US dollar has lost value a lot in comparison to gold. Auto makers can lower the prices for ICEV's more than EV, because they sell more parts for ICEV's that break down more often. The high reliability of EV means less profits from parts sales due to fewer subsequent parts sales.


" Auto makers can lower the prices for ICEV's more than EV, because they sell more parts for ICEV's that break down more often. The high reliability of EV means less profits from parts sales due to fewer subsequent parts sales."

RP explained why automakers battle EVs so much. They know EVs are better for customers - worse for auto profits.

Then, in 5 model years, Tesla comes along showing how much ICE retarded personal transportation for decades.


@kp, when you write about solar/electric power, it's like a 10 year old explaining cars, which he can't operate and never owned.

When's the last time you installed a solar panel or even used a scope?

Even the lowly Harbor Freight system needs a site, cabling, battery selection, inverter for AC, voltage measurements, ..

For a just couple hundred bucks, people can produce their own electric power and learn clearly why your nuclear/utility party line is just a monopoly hustle.


Electronics getting cheaper:
There are several effects here: moore's law and mass production/product maturity.

Things that use information, like computers and to an extent LCD TVs are subject to Moore's law where the number of transistors / area doubles every 2 or so years.
Thus, computers, smartphones and most digital electronics get spectacularly cheaper and better.

Things that are power based, like EVs and solar cells etc are subject to the normal laws of mass production and product development. They get better over time, but say 10% per year, not 100% / 18 months.
The solar panel price decline has also been due to a huge glut of supply which has seen manufacturers slash prices.
Once equilibrium has been established in the market, the price will stabilise, and improvements will continue, but at a lower rate.

To recap, information can get really small, and is subject to Moore's law (for now), power based applications (like Evs and PV cells) isn't, and is subject to more normal laws of supply and demand and mass production.

“at different times, you've referred to Hanford, WA as a 'paradise' and a 'desert'(on the Columbia River?)”

The Columbia River is considered is considered semi-arid. The Manhattan Project selected the the Hanford Engineer Works because of the remote location and abundant supplies of electricity from newly finished dams. In 1944, it was not a very nice place to live. Dust storms were common and the term 'resignation winds' was coined to describe the effect on the 50,000 construction workers and families living in a tent city.

In 1993, Richland was a very nice place to raise children dispute what Kelly Claims.

“to admit it's not worth it? ”

Kelly is does not know that we stopped making nuclear weapons many years ago.

“when China creates Gen IV reactors ”

China is busy cloning three loop Westinghouse three loop reactors designed in the 60s.

If you are looking for the first country to have a million BEV charged with a new generation of nuke plants watch South Korea.

Kit P


Things like wind turbines, PV, and EV are subject to being really bad engineering ideas. It really does not matter how cheap you make things that to not meet the needs of consumers and do not work very well.

Kit P

“When's the last time you installed a solar panel ”

Just last summer. I got my second solar battery charger for my boat. Also got some new solar PV LED path lights. My bike runs on Kit power.


@kp, do you understand ebikes are pedal-able('Kit power')? All those hundreds of millions of ebikes, including some escooters, ..?

If even you can use solar, stop fighting it.

The wasted nuclear $trillions "not worth it" reference also includes Chernobyl radiation losses, Fukushima Daiichi losses, the 207% billions per reactor cost overrun losses, and incalculable additional unknown nuclear waste losses our children will pay, which have stopped new nuclear construction permits in numerous free countries etc.



Who is paying KP to post so much retrograde biased nonsense?


" Auto makers can lower the prices for ICEV's more than EV, because they sell more parts for ICEV's that break down more often. The high reliability of EV means less profits from parts sales due to fewer subsequent parts sales."

Modern cars rarely if ever have engine problems. If you think that the auto industry is fuelled by the profits from 4 spark plugs every 100,000 miles, you need to think again.

Parts sales are mostly made-up of brakes, suspension, tires, electronics. 15 years of Prius experience have conclusively shown that hybrid cars are no easier on any of these components than non-hybrid cars. There is no reason to believe that all-electric cars will be any different (other than naive optimism, of course).

If anything, manufacturers love full electrics because of the unavoidable failure of the battery. Take care of a gasoline car and it can last a lifetime. Take care of an electric car, and the battery will be worthless within a dozen years, forcing you to purchase a new car.

This will effectively kill the used car market. Nobody will spend a dime on used electrics when they know that the $15,000 battery pack is nearly worn-out.

From Av's link
“added 44MW ”

No not exactly jar dropping. Since 1990, performance improvements at nuke plants have been ben the equivalent to adding 24 new large nuke plants.

In March, just one 'old' nuke added more to the grid than all the 'new' solar. This new source of power will have no ghg emissions, have a capacity factor greater than 90% and not be affected by lake effect snow. The lesson is that we do not have to build ;new' solar plants we can just improve nuke plants.

No new solar!

“stop fighting it ”

I am not fighting solar, I just saying solar does not work very well as a replacement for how the industry produces power.

I have said many times that we should keep building wind turbines and solar as fast as we can. I suspect that generation will return to zero when the PTC ends. I think it is one of the better incentives because it lowers the demand for fossil fuel.
