My favorite so far is easily my customer's E39 M5 that I've been restoring for the last year. We had a high output engine built by Partee Racing mated to a diffsonline race prepped transmission. We recently got it dialed in on the Dyno and the thing is a riot. As far as current gen cars go, the new i4 M50 is an amazing car, as is the new i7. The i4 is just stupid fast and nimble, whereas the i7 is a big luxury boat with more tech squeezed into it than you could imagine. The new M cars are cool, but they don't do a whole lot for me. They feel too numb for what they're supposed to be. At least with the i cars, being electric, I expect them to be more numb and reserved feeling, which they are. But it doesn't take away from the fun of driving them. The only newer M car that I really enjoy is the M2 comp. It's a much more analog feeling car. I'd love to take one around a track one day.

I daily an E39 540i. Mid 90s to early 00s was peak BMW. Also, as a BMW tech, if I made a chart like this, it would be 90% BMWs, and I'm kind of regretting not keeping track over the years. But it would probably be a couple thousand cars 😅

So. It makes perfect sense really. Think about an ice cold water bottle on a hot day. Picture it. Is the exterior of the bottle wet, or dry? Wet. Because when hot, damp air touches a cold, dry object, it condenses into water droplets on the object. Now imagine the bottle is your egg, and the hot summer day is the inside of the egg cooker. The steam from the boiling water in the bottom of the cooker condenses and forms water droplets on the egg. Once the droplets get big enough, gravity takes hold, pulling them down. Down, back into the bottom of the cooker, to be boiled and start the cycle again

When you have a lot of eggs filling the chamber, you have a lot of surface area for water to condense onto, which means a lot of water droplets making their way back down to the bottom. Conversely, when you have one egg, there is less cold area for water to condense onto, so most of the steam goes out of the top of the cooker, which means less droplets make it back into the water. Therefore, you need more water, since a larger percent of that water is escaping, to produce the same firmness of egg and the same cooking time as multiple eggs.

The way the timer works is a bit more technical and I haven't taken one apart yet to find out which of the two mechanisms I'm thinking of is used, so can't tell you for sure HOW it works, but I can tell you WHY it works. Water boils when heat is transferred to it, we know that much. There's a heating element under the metal bowl at the bottom of the cooker, which transfers heat through the bowl, into the water. But we can also think about it as the water cooling down the bowl, and thus the heating element, because that is also happening at the same time. As long as the water is cooler than the heating element, which it is all the way up until it turns to steam and is no longer touching the bowl, it is stealing heat from the element and keeping it at a steady temperature. Once all the water boils off, the heating element can no longer stay cool, and rapidly heats up. That's when the cooker decides to turn off and voila! Perfectly cooked eggs.

The great thing about how they work is that the whole process is very easily reproducible, allowing for perfect eggs every time as long as you put the proper amount of water into it.

Hope that helps!

That's 90% of the sound difference. The rest comes down to cylinder head design, camshaft lobe shape/timing, and the obvious one, exhaust. Which is why two different flat plane engines, with the same displacement, even with identical exhausts, will still sound very different. But cross vs flat plane is definitely the biggest defining factor.

I'm a technician at a dealership that has had EV and hybrid models for years. We don't replace the whole battery pack, only the cell module that's faulty. And when we do, they get shipped back to the manufacturer to be recycled. Every manufacturer that makes EVs does the same as the infrastructure for recycling is already in place. We're not out here taking out entire battery units and throwing them in the dumpster out back lmao. And you can say it's not environmentally friendly all you want, but the math has already been done and proven otherwise. Through the entire life of the vehicle, with lithium mining and manufacturing emissions included, EVs are more environmentally friendly than ICE cars.
