And the first thing i thought when seeing this: and thats why electric motor is the future.

It's so true, isn't it? But we've got a pretty long way to go.

Mazda, whose Z5 engine is being disassembled in the video is introducing a compression ignition gasoline engine in 2019 with claimed 20-30% efficiency benefits! We'll see how that actually holds up in practice.

Kudos for sticking with this project, which has not made you a ton of money overnight, since at least 2012.

I don't mean to underplay the work involved in programming and marketing this project, but just not giving up is perhaps the hardest part of things like this.

nice ad. however, the tech side doesn't seem to have received as much love. #1 PayPal returned me to an invalid URL after finishing the payment #2 I've paid & logged in, nevertheless the website still shows me links to "buy the course".

Sorry to hear this - when you say the website shows you links, do you mean the app? There is a bug that I'm aware of that is pending submission for approval to Apple. I will check the Paypal return right now. Feel free to email me - info@howacarworks.com but I'll find your order and get onto you right now.

I can't deduce your order from your HN name so please do email me.

As a hearing-impaired person, I just wanted to thank you for clearly mentioning that it's subtitled. That shows it's more than just an afterthought, and seals the deal for me!

I don't understand why everyone wouldn't subtitle their content. I used rev.com and it costs $1 per minute and the results are great. So to subtitle three hours cost $240. With many non-native English speakers as customers it is a no-brainer. It's good to hear this too, because the text in that box originally said 'Filmed in 4K' and I only changed it to 'Fully subtitled' at the last moment.

I used rev for transcriptions once and I had to have the file redone twice because the first two transcriptions were useless. Haven't bothered with it since. This was years ago so maybe they've improved.

Really nice work! I did have a slight giggle when the promo at the end says you explain everything about 'modern cars', while you are working on a car introduced 27 years ago. Of course I understand that disassembling a new car does not make financial sense, I'm not trying to be negative here.

I completely agree. This was basically the best choice of car that I could afford to buy and effectively sacrifice to the course (the steering rack, the wingmirror motors - it's all in pieces being modeled) I'd love to do it again with Harley!

Very cool. It's amazing how complex the combustion engine seems, especially compared to an electric motor. No wonder cars have a limited lifetime of typically some 150-200k miles. It's going to be really interesting to our purchasing and maintenance patterns for EVs.

Just re-commenting from above: my Mazda Protege (with the same engine shown in the video) has 233k and is still going strong, doesn't burn barely a drop of oil. Pretty amazing for a 20-year old car.

Any success, ever will have had a period of simply not giving up and continuing until it works. Overnight successes more often than not are years of hard work under the radar.

It took 2,500 photos and 4 days to shoot, followed by about 8 days of photoshopping & grading.

You could've cut filming time in half or doubled it if you had chosen a different engine.

That would have required picking a different car to start with.
