The BMW Z4 Final Edition is the very last of its kind | Evo

Production of the third-generation BMW Z4 is coming to a close, and this is the final version you’ll be able to buy

Seen a few post appearing about this. I know the G29 is a bit marmite, but still a sad day . . .

Maybe they'll come back with a ZEV5 once they figure out where to put 400miles worth of batteries.

Toyota are likely working on their hydrogen Fuel Cell rather than a ton of batteries. IMO hydrogen is our future. It's the most common element in the universe.

They seem to have been working on those for decades now. I wonder if the volatility is the major hurdle they have?
There was talk of adding hydrogen to the street gas in the mains network. I know that boiler maunfacturers' new products are now able to burn hydrogen but there has been no word of if and when the network will do this. Knowing the UK there are probably far too many major leaks for it to be deemed as safe.

Nitrogen is the most common for us, though!

They do have some hydrogen vehicles in their product range. But nowhere to fill up. I suppose it's OK for a company fleet that can fill up at their own base.

Hydrogen is all around us. It just takes so much energy (ie money) to extract it fom the "all around us" and get it into a bottle.

It is certainly more volatile. A spark to ignite hydrogen can be 10 times weaker than one required to ignite petrol.

On the other hand the handling and storage of hydrogen is modern. Super strong containers etc whereas petrol containers haven't been rethunk for a 100 years. Also in the event of a leak, ie a trafic accident, petrol vapour is heavier than air so sits there abovr the puddle around the passengers. Modern hydrogen tank is unlikley to be damaged but, in the event it did leak it leaks as a gas that's lighter than air so immediately.heads for the sky.

The problem is currently cost. Cost to produce it. It can't compete on cost with petrol or battery. Yet.
