Kaizen-san Posted September 20, 2006 Posted September 20, 2006 I don't know if anyone has seen this race car before, but I found it very attractive on a website. (Unfortunately, Lexus might not race it even though they have already built couple of them...) 1
Lexus-CT Posted January 30 Posted January 30 2006 is not that long ago. Here is something that is in the future for the most challenging 24 hour race: https://au.motorsport.com/lemans/news/how-le-mans-is-using-grape-residues-and-hydrogen-to-drive-a-sustainable-future/10479840/ Toyota has a car that could have been ready this year, but rules have changed and hydrogen may not be used in the long race before 2026 -27, but still will be evolved by TotalEnergies and probably will be racing this year in shorter races. It is really well explained why batteries is not future for delivering power to cars. I still hope to last long enough to get a hydrogen car. https://www.designboom.com/technology/toyota-gr-super-sport-concept-15-01-2018/ 2
Lexus Owners Club Posted January 31 Posted January 31 Saw them running Hydrogen cars around the circuit last year, a bit like Garage 56 which is when they trial new technology on the circuit Was funny seeing it leaving a huge trail of water along the length of the circuit .... not sure thats good for the others running slicks 🙂 1
Lexus-CT Posted January 31 Posted January 31 That could be one of the reasons they have postponed to 2026. The more power you want an engine to deliver the more fuel it will need and for hydrogen that will mean more water. Toyota is refining both combustion and fuel cell and only the combustion is sounding like a race car. Do not think the Mirai is pouring out much water when driving https://www.toyota.com/mirai/ but only people living in California have filling stations so it would be worth driving one. No filling stations no hydrogen cars. Still think that even stupid politicians sooner or later will find out why all the electric cars they are pressing people to buy are not helping getting pollution down when the cars are charged with electricity from more than 50% not green power and the power used to make the batteries is many places coming from coal. Sure the electric cars do pollute so much where they drive, but making them just moved the pollution to another place and pollution need no visa to move. Here we had 48 degrees Celsius for a first time on the south side of the island; yes weather is getting more extreme everywhere. 2

No filling stations no hydrogen cars. I drove the Mirai a few years ago at a Toyota press event and one of the questions I had for the technical chaps was to enquire about the H2O button on the dash. They said it is to release the stored water generated as a by-product of the hydrogen conversion. Apparently, it is advisable to release the water prior to parking in your garage. I then also asked whether it was pure water or any other contaminants. They replied it was indeed pure water and although you could probably drink it maybe it wasn't the best source to get a drink. However, if it converted to Beer, then I am definitely putting my name down for a Mirai 🙂 1

Do you know how much water is stored before it must be let out? Was it like driving an electric car, where charging is as fast as filling a gasoline car instead of needing it charging for hours? And more comfortable than the RX? A limousine should be nicer to drive than a SUV.
Lexus Owners Club Posted February 2 Posted February 2 Not sure about the water storage capacity but I do know that when we returned from a drive of about 10 miles it released a considerable amount of water when the button was pressed. However, not sure how far it had been driven beforehand so cannot really say how much is produced over a time/distance and how if differs with demands such as speed or temperature, etc. It is essentially the same as driving an electric car and where it differs is that the energy is provided by a hydrogen fuel cell that delivers current directly to the batteries (which are much smaller in size, weight and capacity than a normal electric car as there is no need to run on stored energy as it is constantly being produced from the fuel cell on demand). All round, it is a superb car (albeit costly to purchase) and has huge interior space and comfort (but not RX level), and have to say I think it is definitely the way forward. The only downside is the lack of available refilling points in the UK (around 12 in total when the car was tested) and mostly around airports for some reason. When there is more investment in the infrastructure then it will become a more viable and attractive option. As a footnote, there is a post in this forum from a few years ago about hydrogen shortage in the US due to cold temperatures, storage and transportation issues, etc.....worth a read I reckon. 2

Lexus Owners Club Posted February 2 Posted February 2 to be fair, I am struggling to find the original post and although I don't think i dreamt it, I'm not sure where it is posted. I seem to recall that it is somewhere in the States and the original poster was discussing the shortage. I asked why there was a shortage and he replied it was to do with the storage and transportation in adversely cold conditions.
Lexus-CT Posted February 3 Posted February 3 There should not be any need for transporting hydrogen long distance as all needed to make it is water and electricity. Mid size plants could supply a gas station with 2 or 3 filling points. A favourable place to make hydrogen would be near coasts where water is abundant and electricity could be made from waves and tide. Would like a Corolla sized hydrogen car, here parking places on streets are made in Fiat 500 size. Do not expect Lexus cars are still made when hydrogen will be available. Cheaper to have only one brand. Nissan - Infinity. Honda - Acura
Lexus-CT Posted February 28 Posted February 28 If latest info from BMW, Honda, Mercedes, Toyota (alphabetically mentioned) are correct I may still have a chance to get a hydrogen car, combustion or fuel cell, as long as I do not have to be in a battery powered car it is fine with me. Toyota will change automotive forever: its hydrogen combustion engine will retire EVs: by La Grada - 02/26/2024 14:00 Mercedes has realized the fraud of EVs. That is why they are once again betting on combustion cars Pininfarina Enigma GT debuts at Geneva Motor Show with hydrogen powered V6 Honda Reveals 2025 Honda CR-V e:FCEV BMW and Mercedes are in talk about finding a way to get hydrogen rolled out in the EU and if they can get Honda, KIA and Toyota on the wagon there may be money enough to get governments interested in helping and it could possibly happen. Supposedly Honda would want to get markedshare and they have 1 car ready and 1 more is to be ready for sale in 2027 so they could be interested in participating and Toyota was very slow to start EV cars for reasons they have not informed, but selling cars that have a limited possible lifespan was not what Toyota has been doing so far. I know I shall not believe all I read - and I do not - but Mercedes has publicly informed that they will continue gasoline car production after 2030 and their market-share immediately went 6% up. 1
Lexus-CT Posted June 16 Posted June 16 Le Mans finished today. Toyota did not win: Ferrari: Hydrogen cars were promoted and expected to race no later than 2027: June 15 was a milestone for the H24, the first electric hydrogen racing car in the MissionH24 program run by the Automobile Club de l’Ouest and H24Project. The H24 opened an unprecedented hydrogen parade, before welcoming the official visit of starter Zinédine Zidane to the starting grid for a legendary photo, and completing its final lap of honor at the Le Mans 24 Hours. A historic day for hydrogen at Le Mans on June 15. Shortly after 9 a.m., the tuk tuk H2 from start-up Systemics completed a range test on the Alain Prost karting circuit. This particular vehicle completed 24 hours of driving, using 2 kilograms of hydrogen and covering a total of over 700 km. Shortly after midday, an unprecedented demonstration took place on the main circuit of the 24 Heures du Mans, with 4 hydrogen prototypes: the H24 from MissionH24, the Ligier Bosch JS2 RH2, the Foenix from Solution F, a subsidiary of GCK, and the Alpenglow Hy4 from Alpine. The latter carried a special passenger, Zinédine Zidane. The parade demonstrated the concrete deployment of hydrogen in endurance racing. All these cars are now on display in the Village Hydrogène. Finally, a few minutes before the start of the 92nd edition of the Manche classic, the H24, with Stéphane Richelmi at the wheel, completed a lap of honor, equipped with the latest evolution of Michelin 71% tires (these tires are made from 71% sustainable materials). This lap of honor was like a bow to the world. What shows efficiency of H2 is the micro delivery van: It is this equation with several unknowns that the French start-up Systemics will attempt to resolve during the week of the 24 Hours of Le Mans 2024. A specialist in soft mobility, the entity wishes to validate this autonomy: driving for 24 hours, with 2 kg of ‘H2 (hydrogen) in the tanks of a tuk tuk. The start will be given in 24 hours, Sunday June 9, at 8 p.m. The unique initiative aims to promote hydrogen as an energy vector for more environmentally friendly mobility. Systemics, a French start-up initiated by Antoine Abou, is taking on this challenge: driving for 24 hours with a full tank of 2 kg of Hydrogen in the tanks of its vehicle, a tuk tuk. The chosen location is symbolic: Le Mans, the Alain Prost karting circuit; The date as well, since this attempt will take place as part of the 24 Hours of Le Mans week. Indeed, the experience will take place in two stages, June 9 and June 14, in 12-hour sequences, on the famous Le Mans karting track. On June 9, meet at 8 p.m. for the launch of this pioneering experience. On June 10, shortly after 8 a.m., the tuk tuk will stop to reach the H2 village, within the 24 Hours of Le Mans circuit, to be exposed to spectators. The team will thus be able to share the lessons learned from this first part of the challenge. Friday June 14, from 9 p.m., she will return to the Alain Prost karting track to complete her challenge, with success she hopes, on Saturday at 9 a.m., a few hours before the start of the 92nd edition of the 24 Hours of Le Mans. Among the drivers in the tuk tuk cabin, we could recognize the pilots of MissionH24, a collaborative program between the ACO and H24Project for the creation of an H2 category in endurance, or even elements of the Sarthe Departmental Fire and Safety Service, concerned by the deployment of hydrogen. 1
Lexus Owners Club Posted June 19 Posted June 19 I was there to watch the race and although the safety car was out for extended periods (bit of an understatement) the race had moments of being quite dramatic, especially at the end when the Ferrari was down to just 2% of virtual power on the last lap. Very nice to see a Lexus participating in this years Le Mans 24 Hours, although the overall performance was slightly dwarfed by the opposition, the reliability was certainly in place Good race but hampered by poor weather 1

Did not stay to see it though. Later we went to Estoril and the hotel there invited us to see the training, when we asked from where the engine noise was coming. Not smart that Toyota number 7 bumps into the Lexus GT3 https://www.youtube.com/watch?v=FOSkcMLg_Gc This Toyota is maybe the 2026 Lexus for Le Mans: https://www.lexus.eu/discover-lexus/experience-amazing/performance/motorsport 1
