Much like how all squares are rectangles but not all rectangles are squares, all boxers are flat engines but not all flat engines are boxers.
Hey the inline engine is the same one as in takumis 86

The R8 never had a W engine layout. They have V8s and V10s. Newer R8s don’t even have the V8 option anymore.

What exactly is the difference between a flat and an inline? how does a flat 6 differ from an inline 6
Benihana (10 months ago)
An inline 6 has all 6 cylinder heads on the same side (i.e. upwards) while a flat 6 has 3 cylinder heads on one side (i.e. passenger) and 3 cylinder heads on the other (i.e. driver's).

One question. Are inline 6 cylinder engines better balanced than V6 engine? Thank you.
macduggles (1 year ago)
Siddhant Dwivedy As a boy, I always wondered why all the Diesel engines were always straight sixes, and then one day I found out.
Siddhant Dwivedy (1 year ago)
Yes. Exactly. That why BMW is using bulky inline 6.. and JLR is also switching to Inline 6 from V6 for their SUVs.
macduggles (1 year ago)
Siddhant Dwivedy You can imagine it this way, if you don't have a working example or model to look at, for every part, piston for instance, moving in one direction, there is another corresponding part moving in the opposite direction.
Siddhant Dwivedy (1 year ago)
macduggles yes. thanks I knew the same thing about the inline 6 engines. Mixed comments online had kept me confused a bit.
macduggles (1 year ago)
Siddhant Dwivedy Yes! V6 engines are inherently unstable and must use counterbalances of some sort or another. Same with V8's and L4's.

Clit Commander transmission takes the rotation of the crank and send it to the drive shaft and then to the differential to turn the wheels and it also has different gear sizes to control engine rpm at higher speeds hence why you see 4 -6 speed cars a ton

Actually, the V4 used in the Saab 96 was made by Ford but was used by Saab. only engine they did make was the 3 cyl two stroke which was showing it's age and was more or less fell out of usage. even though it was quite... the piece of engineering itself. had automatic oil injection and whatnot.

guys... idc how much time goes by. theres nothing better than an old push rod OHV v8. nothing fancy, simple design one camshaft. less parts to wear out. they run FOREVER and thats what matters. can i get a hell yeah please?
rami attia (2 years ago)
thanks for that valuable vid keep it up
Flat engines and boxers are not exactly the same, flat engine is basically a V engine with a 180 degree separation between thecylinder banks. What this means is that in a boxer engine two opposing pistons will always be going the opposite way at the same time while in flat V engine they will move the same way. This gives the boxer layout a better balance. However flat V is usually used with high number of pistons like in the Testarossa so different banks of cylinders will be trying to balance each other out so it does not matter that much.
Phil Parr (2 years ago)
mmmm Mazda didn't invent the Wankel , they bought the idea and the engine from NSU before it became part of vw/audi, I have a friens with an NSU Ro80  that is powered by a 2 rotor wankel engine, you can also see where the audi body style came from and was developed thereon....

Subzero Arctics Porsche and Subaru exclusively use flat or boxer engines :) My Toyota 86 which uses a Subaru engine, is a 2 liter boxer 4 cylinder.
rafaelrp07 (11 months ago)
BMW also uses boxer engines in some motorcycles! Porsche is the premium brand with "know-how" by keeping manufacturing boxer engines for decades (specially in their main model- 911) and Subaru is "normal" brand that has this know-how also. The VW Beetle had boxer engines because Hitler demanded Ferdinand Porsche to design it. Many solutions and engineering in this car became part of Porsche philosophy...some of heritage you still can see today.

2:40 There is no such a thing as a W8 in the R8 and there has never been one. There is however a W12 engine in the A8.
Darius Davis (2 years ago)
+riemjann1 Very right. Volkswagen did have a 4.0 W8 in the VW Passat a while back.
OMG Darian D (2 years ago)
This will definitely get some newcomers confused showing a Audi R8 V8 as a ”W“ engine.
Aristos Christodoulou (2 years ago)
Their is a small but BIG difference between FLAT and BOXER engine.. In the FLAT engine(correct term is "V-FLAT") the pistons move at the same direction while in the BOXER the pistons move in contrast..
Adam Henrickson (2 years ago)

Subie (2 years ago)
+Glenn Ang Thanks for the information 🙂
Glenn Ang (2 years ago)
+Mathew M John The course I am currently studying in focuses more on math than on physics. Physics plays a larger role in civil engineering as they have to build structures that are capable of withstanding the natural forces (wind, rain, snow etc) therefore, just a basic understanding of physics will do.
Mathew M John (2 years ago)
+Glenn Ang  What about Physics? I've heard many people saying that in Engineering they just higher level of Physics that we study in 12th grade.
YES10 (2 years ago)
flat engines, of any cylinders, 4,6,8 whatever and inline 6 are the most reliable designs. My theory is that it has to do with perfect balance. They are using nature to remove any shocks and vibration, which makes the parts stay in the perfect spot the longest. Look at Subaru flat 4. No piston skirt at all. No counterweights on the crank, at all. All the parts are using gravity to stay in place. pistons are laying flat resting on the cylinder wall. Doesn't take much to get them moving side to side. Inline 6 uses physics and rotational angles to make it run smooth and thus very long.

WRONG the Ferrari Testarossa has NO boxer engine, but a flat (180 degree) V12. Look at the firing order!
Simon Coles (3 years ago)
Technically the Ferrari Testarossa engine is a 180 degree V12 because each opposed pair of pistons shares a crank pin as like with any other V-engine design. Porsche 911 6 cylinder boxer engines (and all "true" boxer engines) have each opposed pair of pistons on its own crank pin like in any standard inline engine. A Porsche flat-6 engine isn't appreciably shorter than an inline-6. In the case of the Porsche engine the flat configuration's low centre of gravity and ability be to air-cooled was the more important concern than was minimizing engine length.
