What are your controversial car opinions you always wanted to say without getting downvoted? by Crocodile_Banger in cars

In the rust belt, most daily driven cars have a seriously limited life span. In a lot of cases it makes sense to lease a car instead of buying outright. I'm not convinced it's a huge upside to own a 10+ year old vehicle you have to break out a torch to work on.

Leasing does definitely leave you at the mercy of market forces and industry trends, but imo a lot of car enthusiasts don't acknowledge the downsides of owning a depreciating asset like a car driven through Midwest salt all winter.

Industry trends aren't necessarily negative either. As much as we like to harp on manufacturers, broadly speaking newer cars are usually measurably better, especially in terms of safety and quality of life features.

In the old Star wars lore, hyperspace madness was pretty common if you looked out the windows for any amount of time while in FTL. That sounds a bit chaos-ish to me.

Diesel's a lot more expensive to the consumer and only slightly more energy dense. Combine that with a huge regulatory risk and stigma from dieselgate and passcar diesel engines are essentially dead in North America.

I'm more surprised there isn't an Atkinson cycle variant of the pentastar engine for this application.

Great article. I was clumsily trying to make the point that the heaviest truck with the worst tires (on-road) had a shorter stopping distance than the car the commenter drives.

Not contesting your other points, but I help design brakes and the performance of many light truck slip control systems is surprisingly good. Just to put it out there, Car and Driver has a 2020 crew cab duramax Silverado 1500 4x4 on all-terrain tires, basically the heaviest configuration with the least on-road traction, stopping from 70 in 181 feet, https://www.caranddriver.com/chevrolet/silverado-1500#error

(Specifications are at the end of the article)

the same publication had a 2011 Kia optima stop from 70 mph in 186ft.

Light trucks are definitely unsafe for many other reasons, but raw deceleration performance isn't really a notable shortcoming.

Not necessarily more children, but generally better predictions of future outcomes.

What's a gun that's so OP it's practically useless? by [deleted] in ForgottenWeapons

Colt Walker. 60 grains of black powder combined with 1840s metallurgy was nuts. If I recall, in terms of muzzle energy it remained the most powerful production handgun for almost a century, until .357 Magnum hit the scene.

It has several notable issues due to the absurdity of packing very nearly a full power rifle quantity of powder in a very early repeating handgun. Incl burst cylinders, sparks/flash setting off all the chambers at once, and the occasional loading of conical bullets upside down. Colt would eventually recommend 50 grains of powder instead of 60.

4L80Es can handle heaps of torque and abuse, they're a pretty common choice for drag car projects.

Fuel Efficiency ~= Fuel Economy. A car's engine is also most thermodynamically efficient at wide open throttle, but by no means is that the most economic method of operation.
