  1. okleydokley Around 5 years. And maybe not capacity exactly but definitely range. Practically each new generational model of an EV car seems to double its range. So stretch that to 7 years for some maybe maybe, and quite often, automakers are one-upping each other on effective range every 8 months or so. The Hyundai Ioniq was a class leader very briefly at 130 miles.

  4. I do remember hearing that a cyclist on a day's diet of mostly beef will effectively emit 1000g/km of CO2.

  5. I want to see this rotary hybrid cheaper, lighter, cleaner and in every plugin hybrid possible

  6. The gap tolerances must be extremely tight to keep the H2 where it's needed

  9. Oh absolutely, and it's not just because they deliberately didn't invest in PHEVs & EVs. But let's be honest, any automaker that makes most of its profits on Crossovers will not be spared. Profits begets inflation. Inflation reduces the value of profits, so profit margins must grow, quarterly profits must grow by the demand of investors. Therefore inflation. Eventually buyers will be alienated by the market defined by poor value for money and poor variety. I think this is what the kids nowadays call economic rent. Something that landlords and silicon valley companies are guilty of. And it will eventually implode the global-western economy😮

  11. Yikes If you mean "secondary emissions" like photo chemicals that form smog, then you'd be right. A 45 mpg diesel from the late 90s would emit far more damaging emissions than a 45 gas (or hybrid) car from 2010. Because emissions regulations also evolve

  12.  @helojoeywala6622  hope we can dissect what causes those needs in this fast paced world we're trying to get back to.

  13. Would this be anything like the Napier Diesel Deltics? They had power density? Sure. Awe and wonder? Definitely. Reliability , uhh... But in this world now it's quite near impossible to improve real world economy with an engine only, unless weight is shed, which every crossover is doing. I'd be interested to see the compression ratio (and emissions) that characterize these. And I'd love to see this arrive in the EU at the least. If opposing pistons have been used in locomotives for their high torque output, what would be better to see these in passenger vans and mini buses? Or as a perfectly capable generator engine for a phev commercial vehicle.

  14. That's some hard core EV ownership there, do you live in Canada? Anyways, a rule of thumb for EVs is that whrn nights drop below freezing or even 10C, one should always leave it plugged in (and charged above 80% but not 100%) all night, even a 120v trickle charge is enough to keep the battery warm above ambient. This is mainly due the separator or gel electrolyte used in Li-ions. They're gell based and can deform at extreme sustained temperatires most car manuals would not advise at all to store the batteries at -25C for 24-48 hours (or+50C). In particular, electrified vehicles like the Volt or any plug in with heat managed batteries will actually use battery capacity to maintain optimal temperature or longevity sake - so keep it plugged in. Cars like the LEAF almost exclusively don't and plugging in is the only way to keep its battery warm in harsh winter nights. Evidently, if you ever see a new Prius (not a Prime) with Li-ion cells, be skeptical. Hybrid batteries themselves are miniscule, they can't retain heat. It's known for those cars to completely rely on the engine for up to 20 minutes to avoid stress damaging its frozen battery pack. NiMH is far better for durability.

  19. Y'know the best way to eliminate turbo lag? Slap a big electro-motor or two to it and make it a proper hybrid. This is a mild hybrid to some degree.

  20. Comparing the weight of a battery pack to the weight of an equivalent amount of fuel is a bit disingenuous. The battery is an integral part of an EV. An engine, its fuel talk, cooling system etc cannot work without 67lbs of fuel and visa versa. Internal combustion engine components are also heavy, especially when they're in an executive sedan.

  21. Cool. But Mazda should really just be focussing on electric cars with fixed-rpm rotary range extenders
