How do cars work? It's a simple question, without a simple answer. That's what this channel is for! You could search the web endlessly for consumable information, or you can watch my simple to understand videos. I'm a graduated mechanical engineer with a passion for cars, and my goal is to help other people passionate about cars learn how they work. Hope you find my videos enjoyable; feel free to ask questions!

New videos every Wednesday.

    If I was to buy a SUV with cross country/off road capability, the 2DR Bronco in a very basic trim and powertrain would be my choice. Totally not into the Jeep/Fiat units.

    One question I have Jason, which might be something you can cover in a future video is how power distribution works on an electic car. Would an 800bhp rwd car have two 400bhp motors at the rear, and if they made an AWD version, would they just stick 4x 200bhp motors on each wheel? Keep up the great work.

    this is pretty typical of a US company , we just bought the new mustang GT and it has poor panel fit even compared to our 20 year old japanese car , also the dash had bubbles in it and the vents didnt fit right , the good news is ford fixed it all under warranty but this did make me think that they use lack of quality control as part of their process , ie if the customer complains they will fix it . when we buy HVAC out of the usa it also looks like garbage compared to the japanese stuff

    "pam pul moose y"? Freakin' injunears...I swear. It's "pom pleh moose eh", which is short for "grapefruit" in Franch. Well, at least you didn't say "le croyX". // Regarding weight, why didn't you compare the full weight of the engine/transaxle/gas tank/lines/fuel/radiator/coolant, etc. vs the batteries/motors/trans? I believe that EVs will win that comparison. // Lifetime cost for an EV is far less than an ICE vehicle, too. Lowered fuel and maintenance costs make the ROI on EVs much sweeter. For the Globular Swarming folks, EVs are better than ICE by far. Once density goes up 4x or more, the main argument against an EV will disappear: range anxiety. (Retired auto mechanic here, so I love both venues. So far, I can't afford an EV, so I'm considering making one.)

    8:30 While people buy cars for lots of reasons, the best selling car modes are (historically) boring, cost efficient A-B transports. Camry, Accord, Civic, Corolla etc. Recently that's shifted to CRVs and RAV4s, but the idea still the same. Passenger vehicles, yea I know full size pickups technically lead the list.

    Moral of the story is if you like the 86, buy a 86. If you like the supra, buy a supra. Basically, buy these types of cars (in manual if avail) so manufacturers keep building them.

    I'm not sure why weight is an issue for a car unless it is costing more to drive it. Further more in your weight analysis you assumed that all of the energy of the gas was was being used for locomotion. It's my understanding that gas engines are only able to use about 35% of the energy for locomotion the remainder is wasted as heat. Whereas an electric car is able to covert 90% of its energy to locomotion. So the weight comparison isn't really fair. Also, the maintenance of gas cars is vastly higher than electric cars so when comparing cost that needs to be addressed more. Yes, long trips are still an issue; nobody want to wait hours for recharging. There are other solutions like a complete battery pack change out, but it will take years to get that kind of infrastructure in place. Finally, gas engine cars are not dead but the first nails in their coffin have been made.

    EVs IMHO are more expensive because big manufacturers want to sell ICE cars. I miss the efficiency aspect in your science section. ICE cars are about 20% effective. So 80% of the gas is turned into heat.

    You should also focus on the safety aspect of lithium batteries in cars when in accidents. Police, fire departments and even tow truck/storage companies are worried about batteries shorting and causing a fire even hours after an accident. Batteries can become very unstable when damaged and their fires are difficult to put out.

    you mention thermodynamic efficency of a higher compression ratio. compression ratio is a factor of the fuel octane number and is limited by preignition and detonation, the higher tie octane number the higher the allowable compression ratio and therefore the higher the efficency of the engine. the lowering of the compression ratio from 12 to 10 to 1 negates any savings and advantages made by going to atkinson cycle, however... by using atkinson cycle and ensuring the compression ratio stays at 12 to 1 by reducing combustion chamber volume accordingly will give all the adavntages the atkinson cycle engine can offer and by having a variable timed intake valve in tandem with a knock sensor the compression ratio can be varied to maximum efficency to suit what ever octane fuel is being used at the time.

    Honestly, I would up the ante of oil viscosity on those 0w20 and 0w16 applications a bit regardless of what the manufacturer recommends. The engineers have to make compromises and taking 50,000 miles off of an engine's life so it can meet emissions regulations seems reasonable to me. When they smog check cars, they aren't testing oil viscosity.

  • Paul Standaert

    Some engines' oil recommendation went from the conventional 5w30 oil to 5w20 oil with no engine changes... Such as the Ford Vulcan V6 in the early 2000s. Ram pickups have a water cooled rear differential to decrease rolling resistance by using a thinner oil back there. Keep the thinner oil cool and it works just as well as the thicker oil when it is hot. It is all about trying to gain another half MPG.

    The EV world is still in development and will get more efficient over time just like the IC engine has. There are elctric version in most race diciplines such as Formula E, touring cars, drag racing and rally. That EV that Ken Block throws around is impressive. All these teams are helping the industry test and develop electric vehicles. I read an article that the EU wants all cars electric by 2050 and a lot of manufacturers have stated they will have all electric fleets by 2035. With regards to charging I would say that in the furure new homes will come standard with a power bank that is charged from solar so there would be less drain on the grid. Lambourgini have an electric model in the pipeline and I'm sure other high performance manufacturers will also. The more we focus on the environment and cleaner modes of transport and pass that on toyounger generations the faster the EV market will start to dominate. In Sweden younger generations are choosing to travel around Europe by train as opposed to flying. I think Greta might have had something to do with that. I know the US has along way to go in high speed rail infrastructure but it will happen one day. Connecting long distances using rail networks then EV's for getting around locally seem a perfect match.

    Well hang on! You haven’t discussed availability. That energy stored in the chemical bonds in the gasoline is not immediately available. It has to go through a combustion process to release the energy, transform it into kinetic energy in a reciprocating engine and all the associate losses. The battery energy by contrast is available immediately at high availability with very little friction losses.

    the only thing i can think of is that if this becomes mainstream, you wont just need a string of 10 chrgers, you may have entire parking lots filled with charging spaces and these would likely be called "charging stations" and would also likely be connected to a gas station as im sure gas stations are the most likely to wanna do this. its just gonna mean that a 5 min trip to get gas becomes 10-30 min. im sure alotof people with EVs for just city driving who cant charge at home will go to a station and only charge at the fastest chargers and also only charge upto like 70% since thats the fastest part of the battery to charge. this would probably take the charge times for them down to 10-20 min depending. thats not alot of time. likely you can plug in, smoke (if you smoke) go into the gas station and by the time your done shopping for a snack it should be almost done if not done. even if you sit in the car it doesnt seem so bad to just listen to the radio for 10 min
