Again, EURO6d-TEMP is tested with real driving emissions (RDE) with PEMS, so I don't understand what off-cycle conditions could be. This twin injection is a little puzzling, no one mentioned that one of them is DI and nowhere is mentioned D4-S (Toyota's DI+PFI system). My guess is those two injectors are both in the intake port. Nissan has a similar solution and the say that "This reduces the diameter of the fuel droplets, resulting in smoother, more stable combustion. "
1. 61 MPG is achieved on WLTP, still way more optimistic than EPA 2. Aygo is really, really small car, it won't compete even with the smallest hybrids (Yaris, Honda Fit/Jazz), let alone mid size hybrids. 3. EURO 6d uses real driving emissions (RDE) test procedure, if they can achieve low PM & PN without GPF, that just means the combustion is clean enough because of PFI and possibly other tricks. It will be interesting to see if if Toyota D4-S (direct + indirect injectors) in some of their larger vehicles will need GPF for EURO 6d, I would guess they won't.
I think that more efficient transport of electrons (high conductivity) means higher power and charge rate (C rate). But I don't know what it means if it's 2 times better than Nafion.
The estimate based on NEDC is way out of reality. According to this study average diesel is emitting 117.9 g CO2/km, that means that average diesel in EU is consuming 4.5 l/100 km, what a joke. Manufacturers have been cheating NEDC more and more, every new car had lower consumption on paper but not in reality, but now before WLTP and RDE this game has stooped, because every one want to make the transition with as little diference as possible, so my guess is they stooped "tuning" NEDC 2 years ago, when dieselgate broke loose. Study based on NEDC new car data has nothing to do with reality.
@bhtooefr, Millerized 2.0 B-Cycle TSI engine is supposed to have BSFC of 220 g/kWh: http://www.greencarcongress.com/2017/06/20170627-tiguan.html I would think this 1.5 TSI is in the same ballpark.
@Lad, a hybrid that gets 50 MPG consumes around 40 kWh/100 km of energy from gasoline. Similar EV will consume 18 kWh/100 km. Agree? From this we can have this possibilities: - If EV is 50% efficient then Hybrid is 22% efficient - If EV is 60% efficient then Hybrid is 27% efficient - if EV is 70% efficient then Hybrid is 31% efficient - if EV is 80% efficient then Hybrid is 36% efficient ICEs will be with us for several more years, why not make the best of it? EVs may not need expensive development, but they need resources that we can't easily get for yearly production of 70+ million cars worldwide, that is the reality.
I think Toyota will be OK with their hybrid sales, no other manufacturer will be able to compete with them in the price department. Just give every hybrid a little bigger battery (4-8 kWh), a charger and a nice price tag and they will sell like hotcakes. Who's behind who ... we will see in the coming years, don't take these outlooks for facts.
As far as I understand, the first new battery packs were always made by Panasonic and after couple of years they are then mass produced by PrimeEarth. Prius Prime battery is still made by Panasonic. PrimeEarth was also a joint venture with Panasonic having 60% share, but with Panasonic purchasing Sanyo, they rather sold their stake, because they had too big share of world NiMh production (anti-trust problems). Now they are basically doing the same joint venture all over again, with focus on next generation safer, high-capacity prismatic batteries.
This doesn't seem like much effort to higher efficiency, this reads like "....driving performance...better torque.. mid-range response..." is top priority and fuel consumption is just minimally improved, we will have to wait and see but I doubt this is the right direction for conventional drivetrain. The future for normal gasser IMO is cheap simple efficient engine and aid of electricity for driving performance. You get rid of high pressure DI, turbo, complex exhaust sistem (DI engines will need DPF and some form of NOx treatment) and when you are at it get rid of complex EDC, DCT or DSG ... wait a minute that kind of drivetrain already exists, it's called Toyota HSD :D
Interesting project. The main question is efficiency, I doubt this Tri-Gen efficiency (electricity+hydrogen) is higher than generating only electricity in combined cycle gas turbine. Am I wrong?
With fast charging and cheaper batteries the only real solution to fast charge them is to have batteries in the charging station. Otherwise forget it, 350 kW will be max for a very long time and also good enough for most users. I mean 1 minute, 5 minutes or 10 minutes, not a big deal.
Those are many roadblocks listed there and then the quote: "Fisker says that its scientists are addressing these technical bottlenecks" To me this reads like they haven't solved those problems. There are many players in the solid-state battery, Dyson/Sakti3, Goodenough team, Toyota, Koreans... I wonder who will come up with the first production line, my bet is on Toyota.
Current standard allows 800V (maybe more?), first stations are already build in Europe. With cheaper and more powerful batteries every house will also get batteries as a buffer, so when you charge the car it will be quick and then the buffer battery will charge at a lot slower rate from the grid. You will also benefit a cheaper electricity when "unpredictable" renewable sources will take larger part of electricity mix. Also take note that even you have 150 kWh you must charge over night only what you have used during that day and typical daily drives of average person are really very short. For longer trips we will have to rely on fast charging stations.
The investment is 10 million yen, that is $88,790, is this a joke or am I doing the conversion wrong? http://newsroom.toyota.co.jp/en/detail/18840443/
I wonder if they will run into supply issues with the new Leaf, hope not.
"220 kW of energy in just three minutes." kW is not a measure of energy but power, kWh is energy.
There are many shades of autonomy, for some situations eg. traffic jams, autonomy is a blessing and fairly easy achievable. For other situations it may never be achieved because it would be too risky and driver must take the risk if he want's too drive in the conditions. It's for those long boring drives on the highway where these systems will really shine.
TMC did have working prototype in 2014, they published a breakthrough using sulfide superionic conductors in 2016 (nature.com article), going into production in 2022 does not mean worldwide scale of millions EVs, but something like we have seen with Prius in 1997 only available in small numbers in Japan. The original article in Chunichi paper stated: "Toyota has decided to sell the new model in Japan as early as 2022" In that article there is also this: "Toyota is reportedly planning to begin mass-producing EVs in China, the world's biggest auto market, as early as in 2019, although that model would be based on the existing C-HR sport utility vehicle and use lithium-ion batteries." We can suspect that Toyota will roll out their EVs in 2019, but my guess is they won't go large scale until they have solid-state battery fully tested and ready for mass production (Around 2025?).
Bullshit, e-note is no better than Prius, you are mixing Japan JC08 test cycle with EPA. Prius gets 94 MPG on JC08. Japanese may have more problems with charging at home or don't want't to be stranded on power outages in case of another tsunami.
Where is Toyota TS050 article? :)
Bankrupting business and individuals? 7 year old EURO5 petrol car will get you CRIT'air 1 sticker, only EVs get better green sticker. If ICCT will test individual models, they will have a lot of work to do, what will happen with older models not tested? Who will test Prius from 2005? Will older Prius be baned because of this?
Do I read this correctly? Route is 11 km (small one 6 km) long an bus made only 3 (small one 4) round trips per day? That is what? 66 km (44 km) per day? Not exactly usable is it?
In the end, Hybrid is just a gasoline car that consumes less gas and with prices of gas where they are, people are buying pick-ups and SUVs. IMO, Toyota did a good job in Making Ever-better Cars, so buying a hybrid is not only question of fuel consumption, but a question of better car. Europe is seeing a better sales figures because people are already used to buy better drive for more money. With diesel issues and prices, people in EU obviously like what Toyota has to offer. There are a lot of people that won't just go out and buy EV if they don't have or don't want home charging Installation. EV market is big and has potential to grow, but it will face sales issues at some point, just like hybrids do now.
In the end it comes down to price, I don't know what equipment you get in the "diesel" package, but $24,670 for a Cruise is a hefty price. This is Prius territory. Diesel engine it self may be long term durable, but all around it is not (DPF, EGR, SCR, Turbine, high pressure fuel sistem ...)
And we need study for this NOW? Why not 10 years ago?
