Talk:BMW Hydrogen 7

Different car and engine
The engine shown in the smaller image doesn't belong to the car discussed in this article. The car here is an E68, the hydrogen driven version of BMW7 produced after the millennium. The V12 version of these cars were equipped with a N73 engine, and this had a modified version for hydrogen propulsion. These were denoted as E68 in the manufacturers nomenclature. However, the engine compartment shown is a photo is of an E38 built in 1999, and the engine is an M73.

I guess that the article is mixing up two different cars. As the hydrogen 7 made of E38 around the millennium and a later generation hydrogen 7 made around 2005. The best would be to either split the article into two or describe these separately in the same article. 2001:4C4C:1557:9900:4A0F:CFFF:FE35:FD64 (talk) 18:20, 12 November 2021 (UTC)

Not fuel cell
This is not a fuel cell car, this is a car where the internal combustion engine can run on hydrogen. Hektor 10:06, 13 November 2006 (UTC)

Honda FCX is not similar
Honda FCX is not similar car bicause it hasn't internal combustion engine like Hydrogen 7. —The preceding unsigned comment was added by 91.122.11.243 (talk) 11:17, 16 May 2007 (UTC).

Carbon dioxide emissions
The blurb from Technology Review and the Wall Street Journal DO NOT belong here. This is an article about the vehicle, not an argument about what automakers should be producing. The sentence claiming hydrogen cars are "simply flashy distractions produced by automakers" is an obvious abuse of the Wikipedia system. I propose to remove the related sections.

Done. Drnathanfurious 04:25, 11 June 2007 (UTC)

"Green"-Status of Hydrogen
The small blurb about Hydrogen not being a "green" fuel does not belong here. This article is about the Hydrogen 7, not about the consequences of producing a fuel that it runs on. Proposal to remove and instead hyperlink Hydrogen to a page on its use as a fuel. 66.82.9.59 (talk) 03:27, 1 September 2008 (UTC)

Production time: The Hydrogen 7 is not produced for a limited time only but was produced at actual point of time only with 100 units.Princess0210 14:17, 30 August 2007 (UTC)

importance of oxygen in combution
oxygen importantly affects on the combustion and exhausts. as in the presence of the oxygen the burning of hydrogen will produce water as its only product, as seen by the expression 2H2 + O2 &rarr; 2H2O but when is generally burned with the air it produces the nitrogen by products, so normally this car burns with the air still it has the least amount of the polluting products or hazardous products. it is restricted to use the air for the combustion process as it is not feasible to carry the oxygen cylinders in the car which may further add up into the total weight of the car.
