How Automobiles Work


– On the last few new car shows we got our hands on some
pretty cool new cars. This time, I got to drive a car so new that it’s not even technically made yet. That’s right my babies, daddy drove a prototype. – Aah. Fu– – On the outside, its just
a flat black Mazda three. On the inside, lives
one of the most advanced combustion engines ever. I want you guys to do me a
little favor really quick, forget everything you know
about combustion engines. This one goes: Suck. Squirt. Vortex. Compress. Tons of weird stuff; Squirt again. Lean out. Press. Bang I wanna point out that I didn’t say spark. Today we’re talking about Mazdas, Skyactiv- X. The future of the eternal
combustion engine. Zoom zoom muchachos. (techno music) First things first, this is by far the most expensive car I have every driven, or probably will ever drive. – Aah – It is a ten million dollar car, which they told me after
I drove it around Newport for about three hours. I could have wrecked this whole thing. It’s literally worth more than Donut. I could have put fifteen
people out of work. That’s like at least seven kids who aren’t getting Christmas this year. – Haha – Cause Mazda let Uncle James
drive a ten million dollar car and he bottomed it out on a speed bump. (car wheels spinning) The amazing thing about the prototype isn’t how fast it goes. It isn’t an amazing
rumbling from the exhaust, the craziest thing about
this ten million dollar car is that it feels normal. Must be nice. Feeling normal. It felt a lot like the
current Mazda three, which is exactly what the
engineers set out to do. They wanted to make an engine that was super efficient in any revering. You get great mileage, even when you’re ringing it out. That means you don’t have
to drive like your grandma to get the EPA claimed MPG. You can drive like my grandma. Zoom. Zoom. Mazda is sorta an outlier in the environmentally friendly high MPG, low MPG low emissions game. While most companies are focusing on hybrid and electric technologies, Mazda has decided to
make the most efficient internal combustion engine possible. I mean, what do you expect? These are the same guys who said hey, we should power a
car with a magic triangle. (cartoon music) Okay, so how doe this
ding-dong thing work? Disclaimer, I’m about to
use a lot of words I don’t know the definition of. At times it might seem a little technical or that I might be speaking outside of my
realm of understanding. – A laser. – But pay attention, because I promise it’s very, very interesting. Now you might now that diesel
engines are more efficient because it takes less
fuel to make the boom. The compression is so
high that it actually ignites the fuel without a spark plug. The thing is, their emissions suck. They shoot a ton of crap out in the air that causes cancer and kills
all the trees and stuff. The freaking glaciers all melting and suddenly I got a beach front property. Boom. Boom. Raise the rent. Raise the rent. Mazda set their sights
on diesel like efficiency from a much cleaner
burning gasoline engine with a thing called High compression combustion ignition, or HCCI. Basically a gas engine with no spark. Fudge. Until now, this was
impossible because gasoline is less stable at these
higher compressions. We couldn’t control when
the boom was gonna happen. Boom go too soon your engine goes kabloom. (engine combusting) It’s called ping. Pre-ignition. Bad news for baby. The engines the baby. – Haha – HCCI has a limited range of application. Its only dependable when the pistons are moving really quickly. Because the load
requirements are much lower. For things like idling or
accelerating from a stop, it doesn’t work. Kabloom. Nigh night baby. Mazda realized they could correct this using a thing called
variable spark ignition. Think vtech but with spark plugs. Sometimes there’s a spark, sometimes there isn’t. Sometimes there’s a spark, but it doesn’t ignite all the fuel. It just sets off a tiny explosion that pushed the pressure in
the west of the cyllinder past the spontaneous ignition threshold. Then, all of the rest of the gas ignites because of compression,
not because of the spark. Well, because of the spark, but not directly because of the spark. More in like a butterfly
effect sort of way. – Aaah. – When you’re driving, you might accelerate with spark ignition, normal car boom. Then spark control compression ignition and then cruise at the
super lean sparkless HCCI. So many big words, man I don’t know these words. So this is basically the gist. I think that most of it is correct. There is like ten million
other things they did to make all this work. Some of it they wouldn’t share with us, some of it I forgot, and the rest of it I didn’t understand. We were listening to the engineers talk for about three hours. I felt like I had to raise my hand to go to the bathroom. Turns out I didn’t. Jesse was super
embarrassed and I was like: hey, if you can’t handle me at my worst, you don’t deserve me at my best. And Jesse’s all: Dude, what are you doing? We’re not boyfriend and boyfriend and you’re yelling in the
middle of this press thing. Anyway, all of the tech that went
into this weird engine is truly mind boggling. The most impressive thing
is that it feels normal. It’s not the fastest thing on the road, not even close. But the fact that it’s so forward thinking and based on the idea of
having an efficient car that’s super fun to drive, that’s absolutely exciting. Yo, thanks for watching the new car show Hit that subscribe button.

  1. What SPCCI( spark controlled compress ignition )and HCCI (homogenous charge compress ignition ) are same things ?

  2. Mazda just announced The 2.0 liter Skyactiv-X Mazda3 delivers 43.6 mpg on the new European WLTP drive cycle test. No EPA ratings yet but they could be near the 50 MPG mark.

  3. So they're basically going to make the stroke faster and with making the air vortex so that all the friction in there creates a boom or combustion?

    Cool. Why not.

  4. When you come back to this video after mazda implied Americans don't care about the MPGs and they are not going to release the skyactive X in America initially. But I was super hype, I wanted to supercharged marvel.

  5. I liked the video but i think this video fits reaaally good to Bart from science garage. I miss him

  6. WOW the most advanced internal combustion engine, just in time to be totally irrelevant. So complicated. If only we could make an engine with only one moving part and mad reliable. Forward thinking?

  7. Is it really that revolutionary? Seems like more of a minor improvement to me. What is the actual fuel efficiency gain?

  8. Yep, sooner, or later, Mazda is going to suprpass German engineering, one way, or another !! G' by superior German Tech…Also, because of skyactiv, Toyota has teamed up w/ Mazda, to learn how it's done, in exchange in Hybrid Tech…

  9. So I read through allot of comments and noone said it so here I go….$10,000,000.00 car that's designed to be fuel efficient…like there's so much wrong with that picture

  10. Incredible, first person I ever thought did a Chris Farley impression well, and then they compared it to dr. Evil….ehhh
    , but most definitely sounded like Chris Farley SNL days. God bless you Chris king of comedy no matter what…

  11. Anything is better than electric, but can they please make a powerful, efficient, reliable rotary that I can affordably swap into my fc3s. One can dream.

  12. Ugh.. stupid video meant to hook stupid people. The prototype represents $10mm in sunk costs, but that's not it's value or even it's actual production cost. It's $10MM of R&D which gets capitalized as an intangible like goodwill, not as a physical asset. As for all the OMG game changer, variable spark timing has been done and done forever. This sounds just like the natural extension of variable spark timing that says, yeah, this time no spark. That's an impressive feat of engineering calculus and design, but it's going to be very limited to the particular application. For example, the numbers would all change if they tried to use this engine in a heavier, bigger car (or even a lighter car). So my question is how will it work when the car is being driven by an 80lb teenage girl, vs. when it's being driven by 250 lb. Bubba and his posse of 6'4" guys?

  13. Electric vehicles will never take over unless the depopulation gestapo enforce it. Rising sea levels is a bs theory and we haven't seen any. The whole climate change argument is a deception.

  14. @2.47 while you are right…, the efficacy gain with diesel is due to its engine RPM being controlled by the injection of fuel. Most Gas engines RPM is controlled by a butterfly controlling the volume of air. This creates Vacuum in the intake system witch is a pumping loss in its self. A diesel has no vacuum so it gains VE.

  15. Aaaaaaand THIS IS WHAT HAPPENS WHEN A CAR COMPANY DOESN'T HAVE ENOUGH MONEY TO KEEP UP WITH THE CURRENT OR FUTURE OF ELECTRIFICATION! Unless they move forward, this will be one of the companies that don't exist in the future.

  16. Ok so you can get something close to that by deleting your egr and a couple other sensors and tuning for high air to fuel combo. With a ls3 you can get up to 40mpg and small cars can hit up to 60. ICE no Prius bs

  17. ONE IMPORTANT QUESTIONS SINCE WE KNOW IT DOESN'T NEED SPARK PLUG. HOW MUCH TORQUE DOES THAT ENGINE PRODUCE AND IS IT FUEL EFFICIENT AS DIESEL TOO JAMES?

  18. My girlfriend owns a Mazda Skyactiv and I can honestly say it's an awesome drive. The engine feels refreshing and robust. There's enough power when i need it. Mazda is saving the N/A engine

  19. He didn't really or explain or go into any depth at all about the advantages of this new hcci thing.. So what was entirety the whole point of this video?
