Lots of 20-30 year old designs were crazy reliable. Not always powerful.
My favorite is the Nissan VG30. It has basically been used in some form from the late 70s or early 80s to ~2005. The one in my pickup made 145HP and 163ftlbs in 1986. The one in a 300zx twin turbo made roughly 300HP. Even in the 145hp application it still has a burly crank cradle. They have been known to be dead reliable even as high as 700HP. I've heard of, but not seen, 900-1000HP builds. The later VG33 is basically the same engine with redesigned coolant passages for a larger displacement. Everything swaps over. I have VG30 headers and intake in a VG33. Even the cams swap over. |

Fuel economy and power wasn’t bad considering, but no where near what the ‘other’ Grand Cherokee V6 is capable of, especially with a flash tune:

Years ago i bought a toyota for reliability 94 4wd 3.0 v6 well it turned out everything but reliable burned valve at 60k and again at 100k.sold it bought an 89 3/4 ton burban square body took og engine to 245k replaced with a crate engine and upgrade cam ended up trading in a year later at most on my current 04 2500hd its at 264k and pretty solid just replaced typical wear items radiator at 240k waterpump 245k,knock sensor about same time,right side exhaust manifold 250k and ac last year.All these i could do myself. My inlaws think were crazy for having vehicles over 150k they still think like old days i can replace or rebuild an engine for less than 2-3 current car payments,can maintain our vehicles still and trust them.wifes xterra is 248k she only drives 10 miles a day for work.newer stuff is nice but too much electronics and fuel management stuff that kills them.New ls engines for example no way i would buy a 1500 truck with the afm lifters fail by 100k in alot of cases.I feel that the ls series i have is change of modern engine and the current is the same base with more add ons to fuck things up.Kinda like government simple it works fine try and ad more they fuck up LOL. My commuter since i go from phx to so cal twice a month is a 2002 lancer with 225k my son owned it bought a new car i got this from him he maintained it really good runs solid and smooth new waterpump,timing belt,ac fluids changed often,new struts,new front control arms,etc ill dirve it til wheels fall off but it gets 32-35 mpg compared to trucks best of 14 |

New cars are something alright.
Got a 9 year old BMW. Runs like a scalded dog. Over 300 hp. Still gets 36 to 38 mpg on the interstate/road trips. My first car, back in 1976 had about 80 hp and got 35 mpg on the highway. We just got a 2024 Toyota Rav4 hybrid. Took it to the mountains last weekend. Forty one mpg going uphill and almost 43 coming back down. Three adults and luggage/stuff stacked two high in parts of the luggage area. It goes from gas, gas/electric/electric and you sometimes don't notice it unless you notice the green EV light coming on/off in the IP. No gear shift feel with the CVT transmission which keeps the engine rpm constantly changing. |

There were some extreme outliers from the likes of Toyota and Honda that were bulletproof in the 2000s, but I'm not sure all cars on average were more reliable back then. Even if they were more reliable on average, the US wide vehicle fleet average MPG has gone from ~20 MPG in the mid 2000s to ~25 MPG today, and at $3/gal for gas, you can save $6k over 200k miles on fuel alone.

No. It did not peak at that. It is not even close. The last generation of WW2 era piston engine airplane engines that were in testing and getting ready for production are, IMO, still the most advanced piston engines that ever reached that stage. We have made some strides and materials nowadays can be better but regarding the whole package, no. We have too many restrictions by bureacracies and etc on our new engines. Those guys were even using the excess heat energy from the cooling systems to provide thrust; full water injection setups, superchargers combined with blow down style turbos that use the velocity energy of the exhaust to drive a gear putting power to the driveshaft, and had fuel injection systems that were pretty darn competent and legions more robust than what we get in production. Just one of the WW2 era chryco hemis pulled a bomber as fast as four of the old radials had, and that engine was in prototype phase. Rolls royce had an equally technologically impressive engine in prototype as well. Jets came in and made all that utterly irrelevant to the military and that hard push on piston engine development stopped cold. |

When marveling where we are it's good to see where things started .
 Buick OHV in-line eight engine family Even better than the inline or v8 ;  The Tiniest V8 Engine That Nearly Nobody Used Check out the lack of main bearings and low CR The aspect of smoothness arises from a similar situation as the inline-6 or vr6 , end rock countered in the other half segment . The inline-8 and vr8 are crossplanes . The 8 is smoother because it has more power pulses than the 6 in 720° . It can also have a lighter crank than the v8 because the forces are acting on the same plane as the rocking moment . Then there is one head , one exhaust manifold, and shorter , stiffer crank than a 6 . |

Quote HistoryOriginally Posted By Alien: It is pretty crazy. My 2014 V6 Xterra kicks the ever loving shit out of my old 2000 V6 Mustang and gets better gas mileage. Quote HistoryOriginally Posted By Alien: Originally Posted By Burnsy: I have made a thread or two about it in the past but...I am still amazed after upgrading from my 2006 Chevy Colorado to my 2020 Jeep Grand Cherokee. I am very aware of possible reliability issues with modern vehicles. All the features, the bells and whistles that are not needed and that everything costs insane amounts of money in parts and labor to repair. I am strictly talking in performance though. My GC is the poor people Laredo version with the little 3.6L V6. I am fully aware that it's a dog compared to any sort of actual performance car and even in comparison to the optional Hemi that can come in the same truck. I get that now, 300hp is in everything that is boring and bland and is not at all special. That is not my message. I am speaking in relativity to what a V6 would have or could have done 20 years ago. Holy fuck what a difference. That thing moves that big ass SUV. It is peppy and responsive in a way that I don't think big V8s even were back in the 80s and 90s. I can feel that it's not at all working hard most of the time. That it seems to have gobs of umph in reserve if you put the pedal down to jump into traffic or something. It also gets gas mileage that would have been crazy for the amount of power it can make...not all that long ago. Is it a sports car? Of course not. Is it fuckin impressive for it's weight and class of engine? Maybe I am easy to please but it really is! I feel like the proverbial cave man that has been time traveled into the modern age. The big thing is that compression ratios have gone to 10-12 vs 8.5-9.5 of twenty years ago ...and vvt ...better breathing heads ... * the 4.3 chevy LV1/3 ; 285hp -305ft/lb ....11:1 cr and vvt |

Aluminum heads and iron block always made that a tricky deal . * the Ford 3.8 was initially planned to have an aluminum block too ** and while not an inline they still had pretty good potential being cross-flow |

Straight 8 car engines had short lives because of torsion twisting of that long crankshaft. There probably were some harmonics involved in this too.
Car engines have to operate over a wide range of rpm and this is a problem for straight 8 engines. |

Quote HistoryOriginally Posted By M1A4ME: New cars are something alright. Got a 9 year old BMW. Runs like a scalded dog. Over 300 hp. Still gets 36 to 38 mpg on the interstate/road trips. My first car, back in 1976 had about 80 hp and got 35 mpg on the highway. We just got a 2024 Toyota Rav4 hybrid. Took it to the mountains last weekend. Forty one mpg going uphill and almost 43 coming back down. Three adults and luggage/stuff stacked two high in parts of the luggage area. It goes from gas, gas/electric/electric and you sometimes don't notice it unless you notice the green EV light coming on/off in the IP. No gear shift feel with the CVT transmission which keeps the engine rpm constantly changing. You have an eCVT, not a true CVT. Its a planetary gearset powered by an electrical motor. A CVT uses pulleys, they are fine (until they aren't) with low to moderate torque. Pain to work on. |

A fuel injected minivan will outrun most of the 70's stock vettes and other cars of that era.
I love the classics but a stock GT mustang can be had that runs on crappy pump gas just under 500HP , Shelby is 750 HP and has AC and a nice stereo with a warranty. My 1991 Chevy 3/4 ton truck had a 350 and was around 200 HP and sucked gas. 2016 F150 4X4 3.5 V6 NON-Turbo stock is just under 300 HP and averages 22 MPG. Tech comes at a cost , I just changed #3 coil pack on my daughters Escape. Tech costs more to build and maintain than a rotor , cap , plugs , points , condenser , wires , etc. |

Gasoline Engine technology PEAKED, utterly Dominated with the LQ9, 6.0 liter LS around 2003 with 10.0 compression. that motor, totally STOCK can stand 20 pounds of boost, will push 900 horsepower until you run out of money for TIRES. I think you meant the 6.2L LS3, but still the same family. |

Quote HistoryOriginally Posted By JKH62: Tech comes at a cost , I just changed #3 coil pack on my daughters Escape. Tech costs more to build and maintain than a rotor , cap , plugs , points , condenser , wires , etc. Changed the starter on a '71 Pontiac once in below zero weather, all I needed to do it was 11/32 nut driver for one nut, 5/8 socket for the battery cable on the solenoid and a 9/16 socket for the 2 bolts to hold the starter itself. After disconnecting the battery of course. A 5 minute job, even in below zero weather. I just changed the starter on a N52 BMW, have to pull the intake. Miserable job even in 50 degree weather not to mention below zero weather. |

Quote HistoryOriginally Posted By 72Harley: I bought my 2021 CX5 GTR in October of 2021. The following June I took it out to Yellowstone and touring around Wyoming and South Dakota. Put 6k miles on it in two weeks without a problem. That car was made for road trips. I gave my '19 CX5 to my son and got a CX50 with the turbo. I am a huge fan of Mazda products. My dad just go a 24 CX5 and love it. He came over from a Chevy Equinox which is a dog POS. The 2.5 Turbo engine is a great one. I normally have 89-93 in it and it only gets 87 if my wife puts gas in it. I like the added HP when I drive it. The metric for a performance motor has always been 100hp per liter. The 2.5T gets that. |

Quote HistoryOriginally Posted By JHMC79: The 4.0L Toyota V6 in the 4Runner and Tacoma, which was released about the same time, is absolutely bullet proof. It's been phased out of the Tacoma for years now and is about to be replaced in the 4Runner with a turbo 4cyl. The 5.7L V8s in the Tundra and Sequoia have now been replaced with a turbo V6. The list is endless. The 1GR-FE was pretty solid once the head gasket redesign came in. Prior to 2008, failure before 100k wasn't uncommon. For a number of years people shat all over this engine, tho the failures were never universal, it was poorly designed. Otherwise beyond the air injection pump issues and the knocking problems that could lead to damage (eventually fixed by a ECU revision detuning), it's better than most. FWIW I've had less issues with the 2GR-FKS I've also owned - tho fuel pumps seemed an issue during one run. The 3UR-FE - your cam tower seals are gonna leak and they'll need to be fixed. With oil consumption makes it important to check oil level regularly. PCV has some issues as well. It isn't uncommon for the water pump to take a dump, often within warranty period. I've had a fair number of both, and have experienced all prior to cycling them out @200-250k. My guys normally get good service from them for a good time after, many still have them. So they'll do well if you take care of them. Overall I've had the best luck with 2UR-FE 4.7L. Maybe it's the dimness of recollection/randomness favoring, but I don't recall any major issues. The ones I've driven personally have gone well past 200k w/o much beyond normal maintenance. Tho I did water pumps every t-belt service and starters every other. Also have a very good management program which I think maintains the vehicles to higher level than many. Sell the vehicles to the drivers for a nominal fee net, as a reward for employment longevity and keeping the trucks in good condition. If guys know they will get the truck, they take better care, mostly. |
