Η Toyota έδωσε μερικές νέες πληροφορίες σχετικά με την επόμενη γενιά του Prius αλλά και για το αυτοκίνητο υδρογόνου που ετοιμάζει. Ο Satoshi Ogiso, Managing Officer της Toyota, μιλώντας σε συνέντευξη τύπου στο Michigan, δήλωσε πως:
Το νέο Prius θα φέρει μαζί του και μια νέα εποχή για ένα ευρύ φάσμα νέων οχημάτων της Toyota και της Lexus. Θα είναι το πρώτο αυτοκίνητο που θα διαθέτει τη νέα γενιά υβριδικών κινητήρων, οι οποίοι θα προσφέρουν σημαντικά βελτιωμένη οικονομία καυσίμου, σε ένα πιο συμπαγές πακέτο, το οποίο θα είναι ελαφρύτερο και θα κοστίζει λιγότερο στη κατασκευή του.
Παράλληλα οι κινητήρες θα είναι πιο αποδοτικοί, με καλύτερες επιδόσεις και θα διαθέτουν τη τελευταία λέξη της τεχνολογίας σε ότι αφορά τον ηλεκτροκινητήρα, τις μπαταρίες και τον βενζινοκινητήρα. Θα διαθέτει μικρότερο ηλεκτροκινητήρα, πιο αποδοτικό βενζινοκινητήρα και καλύτερες μπαταρίες που θα προσφέρουν υψηλότερη ενεργειακή πυκνότητα.
Το Prius θα κατασκευαστεί πάνω στη νέα αρθρωτή πλατφόρμα της Toyota, Toyota New Global Architecture (TNGA) η οποία προσφέρει χαμηλότερο κέντρο βάρους και αυξημένη δομική ακαμψία. Θα διαθέτει καλύτερη αεροδυναμική και πιο άνετο εσωτερικό, αφού όπως χαρακτηριστικά δήλωσε ο Ogiso:
Η νέα γενιά του Prius θα διαθέτει σημαντικές βελτιώσεις στον σχεδιασμό του εσωτερικού, τη διάταξη και την ευκολία χρήσης που θα προσφέρει.
Σε ότι αφορά το νέο Prius Plug-in Hybrid, αναπτύσσετε παράλληλα με το “απλό” Prius, με τον Ogiso να επιβεβαιώνει πως θα διαθέτει ένα επαγωγικό/ασύρματο σύστημα φόρτισης των μπαταριών, με την Toyota να αναζητά τρόπους ώστε να επεκτείνει την ηλεκτρική αυτονομία του αυτοκίνητου.
Τέλος ο Ogiso επιβεβαίωσε πως προχωρά κανονικά ο σχεδιασμός και η ανάπτυξη του οχήματος υδρογόνου που ετοιμάζουν, σε συνεργασία με την BMW, το οποίο θα βγει στην αγορά μέσα στο 2015. Πρόκειται για ένα μεσαίου μεγέθους τετράπορτο sedan, με το πρωτότυπο του να παρουσιάζεται στην έκθεση του Τόκιο τον προσεχή Νοέμβριο. Θα αποτελεί την έκδοση παραγωγή του FCV-R Concept το οποίο θα έχει κόστος κοντά στις £70.000 (€85.000) και αυτονομία κοντά στα 676 χλμ. Μάλιστα στην έκθεση της Φρανκφούρτης η Toyota θα παρουσιάσει και ένα νέο πρωτότυπο υδρογόνου που θα εξοπλίζει με 21 kW μπαταρίες και το Hybrid Synergy Drive σύστημα.
Toyota to Launch ‘New Era’ of High-MPG Hybrids, Expand Its Global Hybrid Rollout
- Early information on Next-Generation Prius
- VP Carter challenges industry: 5 million U.S. hybrid sales by end of 2016
- Global verification tests of new wireless/inductive charging system
- 2015 hydrogen fuel cell vehicle at Tokyo and CES shows
YPSILANTI, Mich., August 28, 2013 — Want to save money and gas? Toyota plans to help consumers do both.
Promising continued gains in fuel economy, Toyota Motor Corporation (TMC) Managing Officer Satoshi Ogiso outlined the launch of a new era in hybrid technology with the arrival of the next-generation Prius, while Toyota Motor Sales (TMS) Senior Vice President of Sales Bob Carter issued a challenge for the industry to significantly step up its commitment to hybrids as a core technology.
As a backdrop to these announcements, Toyota gathered in one place for the first time ever the entire Toyota and Lexus global hybrid line up. The company has sold more than 5 million Toyota and Lexus hybrids worldwide. The environmental effect has been an estimated 34 million ton reduction in C02 — the equivalent of taking 4.8 million vehicles off the road.
“I would like to see us — as an industry — accomplish the same thing in the U.S.,” said Carter. “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.”
Stressing Toyota’s further commitment to industry hybrid leadership, Ogiso announced that “when the next generation Prius arrives, it will begin a new era for a broad range of Toyota and Lexus vehicles” and will be “the first to introduce a substantially improved family of hybrid powertrains.”
Between now and the end of 2015, Toyota plans to introduce 15 new or redesigned hybrid vehicles globally. These new hybrid powertrains will deliver significantly improved fuel economy in a more compact package that is lighter in weight and lower in cost. Ogiso said the performance of this new generation of powertrains will reflect significant advances in battery, electric motor and gas engine technologies that are part of Toyota’s larger strategy towards the electrification of the automobile through hybrid, battery electric and fuel cell technologies.
Ogiso used the next-generation Prius as an example.
“The current Prius has held America’s fuel economy crown for many years,” said Ogiso. “In its three generations, Prius MPG has improved on average by about 10 percent, each generation. The challenge to continue to improve at this rate — to beat your own record — becomes very difficult, but makes it all the more motivating. We are very motivated to beat our record.”
The next Prius will feature improved batteries with higher energy density – the relationship between the battery’s output and dimensions. Toyota, already a leader in advanced drive battery technology, has stepped up its research, development and production capacity of both nickel-metal hydride and lithium-ion and will use these technologies where appropriate in its expanding focus on electrification of the automobile. Toyota has also ramped up development on new battery technologies like solid state and lithium air, as well as devoting resources focused on chemistries beyond lithium, such as magnesium and other low-valence materials.
The next Prius will also feature electric motors that will be smaller in size. He noted that the current Prius motors have four times the power density of the first model and that “the next will be even higher.”
In addition, the thermal efficiency of the gasoline engine in the current Prius is 38.5 percent. The next-generation will boost that level to more than 40 percent – a world best.
The next Prius will also utilize Toyota New Global Architecture (TNGA), featuring a lower center of gravity and increased structural rigidity, which will contribute to greatly improved driving dynamics.
Improved aerodynamics will contribute to an all-new exterior design. Ogiso promised a roomier interior and significant refinements in design, layout and ease of operation.
Ogiso also said the next-generation Prius Plug-in (PHV) is being developed in parallel with the standard Prius model.
“We have been listening very carefully to Prius PHV owners and are considering their requests for additional all-electric range. We have also heard from owners that they would like a more convenient charging operation,” Ogiso said. “In response, we are developing a new wireless/inductive charging system that produces resonance between an on-floor coil and an onboard coil to transmit power to the battery, providing charging without the fuss of a cable.” He said verification work on the system will be conducted in Japan, the U.S. and Europe in 2014.
Work is also progressing on Toyota’s first commercially available hydrogen fuel cell vehicle, a new mid-size four-door sedan whose concept will be unveiled at the Tokyo Motor Show in November. That vehicle will make its North American debut in January at the 2014 Consumer Electronics Show in Las Vegas, where Bob Carter will discuss the role of Toyota’s U.S.-based engineering team in its development, as well as preliminary plans for introduction into the U.S. market.
Carter said that the hydrogen fuel cell will utilize core hybrid technology and will be a primary element of Toyota’s future mobility strategy.
“Toyota currently accounts for more than 60 percent of U.S. hybrid sales and 70 percent of the nearly 3 million hybrids on U.S. roads today,” said Carter.
“Over the past 5 years, the percentage of hybrid sales at Toyota has grown from 10 to 16 percent of our total sales mix. Honda is less than 2% and Ford is less than 3%. And while hybrid as a percentage of the total market is just under 4 percent, we believe that it can…and must grow.”
TOYOTA GIVES SNEAK PREVIEW OF ITS HYBRID FUTURE
Next generation Prius to lead new era of hybrid technology
- Lighter, more compact and more efficient Toyota hybrid powertrain to debut in next generation Prius
- Toyota advances in battery, electric motor and petrol engine technology will secure better fuel economy, reduced emissions and lower costs from a small, lighter and more efficient system
- Powertrain design will be adopted by a wide range of future Toyota and Lexus hybrids
- Next Prius will also adopt the Toyota New Global Architecture, with a lower centre of gravity and stronger structure delivering improved dynamic performance
- Next generation Prius Plug-in developed in parallel with standard Prius
Toyota will spearhead a new era in hybrid technology with its next generation Prius, promising further gains in fuel economy and reduced emissions. As part of its focus on its hybrid leadership and achievements at the Frankfurt motor show, Toyota has provided a sneak preview of the technical advances that will underpin future Toyota and Lexus hybrid models.
Emphasising Toyota’s continued commitment to auto industry leadership in hybrid, the next generation Prius will be the first in a broad range of Toyota and Lexus vehicles that will make use of a substantially improved family of hybrid powertrains.
These new powertrains will deliver significant improvements in fuel economy from a more compact package that is lighter in weight and lower in cost.
Their performance will reflect the significant advances Toyota is making in battery, electric motor and petrol engine development in its wider strategy to deliver electric vehicle power through hybrid, battery electric and fuel cell technologies.
In each of its three generations, Prius has delivered an average reduction of 10 per cent in its CO2emissions. Toyota’s challenge is to continue to improve at this rate.
The next Prius will feature improved batteries with higher energy density, which means greater energy storage capacity within a smaller unit. Toyota, already a leader in advanced battery technology, has stepped up its research, development and production capacity for both nickel metal-hydride and lithium-ion, and will use each technology where appropriate in it expanding focus on vehicle electrification. It has also ramped up development of new battery technologies such as solid state and lithium-air, and devoted resources to chemistries beyond lithium, such as magnesium and other low-valence materials.
The next Prius will use smaller electric motors, but with a higher power density. The motors in the current model have four times the power density of those used by the original Prius back in 1999, and the improvement will be higher still in the next generation car.
The thermal efficiency of the petrol engine will improve, too, from 38.5 per cent currently to a world-best of more than 40 per cent.
The next Prius will be constructed according to the Toyota New Global Architecture, bringing a lower centre of gravity and greater structural rigidity, contributing to greatly improved driving dynamics.
A focus on raising aerodynamic performance will deliver an all-new exterior styling, with a larger interior and refinements in design, layout and ease of use.
The next generation Prius Plug-in is being developed in parallel with the standard Prius model. Toyota has learned from current Prius Plug-in customers that they would like a greater all-electric driving range and a more convenient charging solution. In response, Toyota is working on a new wireless/inductive charging system that produces resonance between an on-floor coil and an on-board coil to transmit power to the battery – simply put, this provides charging without the fuss of connecting a cable. Verification work on this system will be carried out in Japan, the USA and Europe during 2014.
TOYOTA PREPARES FOR 2015 PRODUCTION FUEL CELL HYBRID VEHICLE LAUNCH
Technical presentation at Frankfurt motor show
- Toyota on course to launch its first hydrogen fuel cell vehicle in 2015
- Technology builds on Toyota’s world-leading hybrid powertrain expertise to capture the zero-emissions potential of hydrogen-electric system
- FCV-R concept signposts Toyota’s progress towards developing an affordable four-door saloon model for production, with no compromise in interior space and a cruising range of more than 300 miles
- FCV-R powered by a Toyota fuel cell stack with world-leading power density of 3.0kW per litre
Toyota believes the Fuel Cell Hybrid Vehicle offers the best solution to the challenges of energy sources and emissions, with hydrogen as an ideal, ultra-clean fuel. At the 2013 Frankfurt motor show (from 10 September) it will demonstrate how it has overcome some of the historic barriers to developing a marketable fuel cell vehicle and how it is closing in on its goal of achieving a driving range and performance comparable to conventional petrol and diesel engines, but with no harmful tailpipe emissions.
Toyota applied its successful Hybrid Synergy Drive technology – the power system used by Prius and its other full hybrid production models – in its FCHV development, replacing the petrol engine with a fuel cell and the conventional fuel tank with high-pressure hydrogen tanks. The FCHV uses the same electrical components as a full hybrid powertrain, as well as a 21kW battery to store energy recovered by its regenerative braking system.
Having first unveiled its FCV-R concept at the 2011 Tokyo motor show, Toyota has continued to make progress towards its planned introduction of an affordable FCHV saloon model in Japan, the USA and Europe by 2015. Development of the production model has seen a focus on significant cost reduction, durability, reliability and improvements in well-to-wheel CO2 emissions.
The FCV-R concept is 4,745mm long – 35mm longer than an Avensis saloon – 1,510mm high and 1,790mm wide. Tested by Toyota (in line with official Japanese JC08 criteria) it has achieved a maximum driving range of about 420 miles, producing no CO2, NOx or particulate matter emissions. The only by-product of the hydrogen fuel cell when driving is water vapour.
Creating a car that’s a practical proposition for today’s motorists has required particular attention to the design of the fuel cell and the hydrogen fuel tank. Toyota has succeeded in downsizing the fuel cell stack by achieving the highest fuel cell power density yet – 3.0kW per litre. A marked increase in the fuel cell stack’s energy efficiency has allowed for the size of the vehicle’s fuel tank to be reduced, so that the latest design features two tanks rather than the four originally envisaged. This also allows different materials to be used, which has a positive impact on overall costs.
The twin fuel tanks and the fuel cell stack are located beneath the vehicle floor, which means there is no impact on the cabin and load space.
Toyota expects FCHVs to reach full mass-market commercialisation during the 2020s, by when it aims to be selling tens of thousands of vehicles annually. This market growth will be supported by the wider roll-out of fuel cell vehicle technology; the development of hydrogen refuelling infrastructure that will bring filling stations within easy reach of greater numbers of people; and cost reductions that go hand-in-hand with a maturing technology.
Toyota’s fuel cell stack technology has consistently enjoyed performance leadership, the company having launched its R&D programme in 1992. Since then it has secured significant improvements in every aspect of FCHV operation.
As mentioned above, the fuel cell to be used in Toyota’s production FCHV currently achieves the world’s highest power output density at 3kW per litre. Compared to the fuel stack Toyota deployed in its 2008 FCHV-adv model, the new unit has twice the power density while being half the weight and half the size.
The progress made in energy efficiency is also revealed in the vehicle’s range, which, according to Toyota test data (in line with the official Japanese 10-15 test cycle), has improved from about 205 miles to more than 350 miles. At the same time, the fuel cell has a greater operating range, with the use of new materials in its construction making cold start possible at temperatures as low as -30°C.
Cost issues have also been tackled, with the current fuel cell system, including the stack and high-pressure hydrogen tank, one-tenth the cost of that used in the FCHV-adv. Toyota aims ultimately to reduce this by a further 50 per cent. Currently a vehicle price tag of less than £70,000 is thought attainable, but Toyota is working to reduce costs even further before bringing its first model to market.
