  2. Basically a 4 pot engine cannot by definition be balanced as well as a V6. The firing on a 4 is every 180 degrees but a V6 is every 120 degrees. As far as I am concerned a V6 wins every time.

  3. Scotty: i really like your video on engines. I see that you are a big fan of inline 4 over V6. My question is: I'm getting a ford mustang (if i can afford it i want a GT (V8) so no problems there BUT if I can't afford it then do you like the inline 4 TURBO over the V6 engine in a Mustang?? I'm mostly driving it to run errands and about town..not really taking it highway driving . Which would you think suits my needs better?

    thanks for any and all help.

  4. My main mileage placed on my car in the last 6yrs has been Hi way miles I like somewhat of a slightly larger car for safety many deers out in the counties I travel thru I like to cruise 80-85mph and I just do not feel comfortable with a 4 cylinder engine at those speeds if my main mileage was in the city I would definitely go with a 4 cylinder engine.

  5. Both of the subarus i have have nearly 300k miles. One has 290k the other has 260k. The 290k one is a 02 wrx, original engine, had first hg done at 150k and having a modded 207 being built for this summer. Pretty satisfied with subaru at this point.

  6. As far as v6 vs i4 for new car purchases, I'd say ignore reliability and repair costs if you will own it before warranty expires, if your like me and drive 20k+ a year on avg, get a cheaper car and smaller engine. Each of our wallets speak different languages though.

  7. Scottys probably right but my 3.8 litre buick runs and starts everyday . Coming up to 600,000 kms ! Course it leaks oil and is falling apart which is partially my fault. I see lots of them in better shape but we havnt put any money into it for years. Just waiting for it to die but it wont.

  8. Why didn't you mention Mercedes Benz invented the first car. Oh, that's rught, YOU DONT LIKE THEM! Stop desecrating the Mercedes brand. It's distasteful and insulting to a company that actually puts thought process behind their vehivkrd. Not like the mimicking copy cats that you put on a pedestal,Toyota

  9. lol Scotty, sincerely twin turbo V6 is better than any I4, the vibration with I4 gets worse as the car ages and even in high speed ( greater than 80km/hr) for new ones, the I4 is just a boxer engine with some turbo tweaks

  10. Ford failed twice with Triton he's right about trannies and rear ends but gm makes the best truck engines 350 TBI and the ls were amazing the best truck engines in fords were the 300 straight and where did thoughs go

  11. Yeah…inline 4s always sound like a bag of hamsters being shaken up. I can't stand it. A V6 isn't amazing either but it's better. And then there's the fact that my V6 makes power and torque figures that start with 4. 300ish horsepower is merely adequate, and 200ish? Pedestrian. Don't even talk to me about under 200hp, I might cry and hand you a bus pass.

  12. I have a 2002 Nissan Cefiro, 2-litre V6 (VQ20DE) with 214k miles. Only minor oil leaks coming from timing cover but everything still runs fine and smooth. Driving on a steep road like climbing a hill is great though! I could rev up to 4500 RPM without the engine making any noise. It's butter smooth damn! No major probs so far. Probably because I don't do abusive driving lol. Anyway the whole car condition is just like factory condition, except the very small oil leaks 😛

  13. I think the problem with the modern 4 cylinder is that they are pressured up with a turbo and likely will not last as long as a V6. (Also, I have never had very good luck with 4 cylinders that I have owned so am a little biased).

  14. Of course japanese make the best v6 engines, my old toyota with the 3.5 v6 was very torquey and smooth. Got rid of that car, wanted a manual and went for a subaru.

  15. Camara has a5cilynder turbo using 305 hp. Ford svt 4s are r the highest producing hpnew technology has increased in line performance I saw an in line 6 produce 500 hp. The bigger the engine no longer mean more hp.
    Old days cars had huge engines that created only 185 hp like the 60 dodge chargers and. First corvette came out with a 250ci in line 6.

  16. After going from a four cylinder to a V6 Accord, I can only say that, given the choice, I would NEVER go back to a four cylinder, at least in a car of the size and weight class of the Accord. Sorry, but this video is just incorrect on SO many fronts. A V6 is just better in pretty much every way:

    1. Power. As if this really needed to be brought up. The V6 just accelerates and climbs hills effortlessly compared to the four cylinder. The four cylinder by comparison just feels like it shouldn’t be in a car that big. It seems like it has to work hard at anything other than cruising on level ground. Also, while the V6 can stay in a given gear, the four cylinder requires a whole lot more shifting to handle such things as passing and climbing hills.

    2. Gas mileage. Honestly, I have not seen a difference. Maybe this is due to the fact that the four cylinder Accord was automatic and the V6 a six speed manual. But I can’t see transmission choice amounting to more than a few MPG. But even if the V6 does a little worse on gas with a particular car, it never seems to be more than a few MPG worse. In other words, with a four cylinder, you give up LOTS of power to get a fairly tiny improvement in MPG. Unless you just flat-out don’t care about power, it’s not worth it.

    3. NVH. The V6 is naturally a better balanced engine than a four cylinder. Consequently, it is much smoother and quieter. A V6 is also smoother and quieter due to the fact that it has to work a whole lot less hard to propel the car.

    4. Reliability. Contrary to what this guy says, I have NOT found four cylinder engines to be reliable. Quite the contrary. The most unreliable engine is an overworked engine – one that has to work REALLY hard just to get a car moving. Sound familiar? Yes, a V6 may have more moving parts. But if these parts are less stressed, they are less likely to fail. It should also be noted that, compared to a four cylinder engine, V6 engines tend to have shorter strokes and longer rods. Both of these factors reduce internal stresses, which improve reliability.

    5. Sound. This may be a silly one. But it can be important to many. Let’s face it. A V6 just has a MUCH nicer sound than a four cylinder engine. While the sound of a four cylinder engine is often described as sounding like a sewing machine, a V6 sounds MUCH more musical.

  17. V6 engines Do Have vibrations!That's because it is actually 2 three cylinder(odd) engines in one. Three cylinders are unbalanced engines. 4 cylinder engines are very smooth. Inline 4 engines Have vibration over of 2L. V4 have less vibrations and Flat 4 is an ultimate vibration free configuration of an engine!

  18. The old VW air-cooled, 4-cyl, 53 hp boxers took me hundreds of thousands of miles with only one engine failure. Of course, it was in our camper van (which VW called a station wagon, and weighed more than the Bug ). And we were trying to drive across the Sonoran Desert in the daytime (100+ degrees F). The bus had a perfect right to blow its engine. We hitchhiked into Zachetecas, Mexico, where we found a cheat who rebuilt the engine. It limped out of Mexico (the Federales demanded we remove it) on two or three
    cylinders. But it left under its own power. Conclusion: Who needs 3 cylinders?

  19. You forgot to mention the inline 6 engines.

    Also, recommanding a Ford I4 Ecoboost is probably a bit of a mistake. Yes you can service it bettter, but damn are you going to service it a lot. Don't know if they corrected the problems of this ominous engine for the Mustang though.

    And you didn't mentionned the Lexus V6, that are generally foolproof until the death of the owner. I would prefere that to an Audi I4T any day.

  20. Having owned inline 4 and 5, v6 and v8 cars i have to agree with scotty. More cylinders=more maintenance costs and double problems. Sure they sound nice and have nice torque and hp but the downsides are increased fuel consumption and decreased reliability. And from my own experience i can say that a simple japanese inline 4 will probably outrun any american v8 more than 3 times. American cars have a high comfort to value ratio but very poor price to quality ratio in comparision with the japanese. And then the german wonders. Poor quality and expensive parts and repairs. They are good brand new but total junk after 60k miles really…
