Mezcal is the overall term for distilled agave spirits. As such, there are many types of mezcales, made in different regions in Mexico, using various cultivars or even different species of agave. Tequila is a specific type of mezcal made from blue agave. It also has denomination of origin, so additionally for it to be legally called tequila, it must be made in the state of Jalisco or the bordering municipalities (counties) of Michoacan, Guanajuato, and Tamaulipas.

In practice, people separate tequila from the rest of mezcales, much like people set apart champagne from "wine", despite how champagne is literally a specific type of sparkling wine, made in the French region of Champagne.

1. A lot of cars are just bigger than they were 15 years ago, comparing within the same segment of any type of vehicle.

2. Cars have way more airbags built in now compared to any time in the past

3. Most cars have way more electronics now, again compared to any time in the past. Cameras, blind spot sensors, tire pressure monitors, general “infotainment” systems

Safety requirements have risen. Cars are required to survive higher speed crashes with less injury to passengers which means more air bags and stronger construction. Then added tech plays a role, a rear camera by itself doesn't weigh a lot but add supporting bracketry, wire harnesses, and the computer power to render it and you get a few pounds multiply that over every new piece of tech and it adds up.

Dude specifically wrote "City cars" in his answer . . .

As pointed out they are, but the market will not really pay for them.

The manufacturers make more profit on large higher performance vehicles, and have had to sell their smaller high efficient vehicles at a loss for years to meet their fleet efficiency standards (CAFE requirements). It does not cost 3x as much to make a $90k car as a $30k one.

So the typical efficient car buyer is not really interested in paying for efficiency, they are buying on price.

I'm sorry you guys in North America don't have diesel options for most cars, not unusual to have a hatchback in Europe that can achieve 60+ mpg my 1.6l diesel 4x4 crv gets 55mpg. Not as many cool sounding v8s here tho 😄

If it’s heavier, you need more power for the same performance.

Nobody asked for more power though. Besides high schoolers, nobody is getting accords for power/speed . I want that more efficient engine in lighter weight body to maximize efficiency.

So, you've driven a Tata?

You're mistaking something having a definition by being axiomatic. Imaginary unit is a construct that's a consequence of first defining natural numbers using Peano's axioms and then (in layman's terms) further "creating" other, more complex structures based on your previous results.

I agree with your other statement - imaginary numbers are just an ordinary mathematical object and there's nothing special about them. I consider real numbers to be the really, really weird ones (transcendental numbers anyone?). Imaginary numbers are just a simple extension of that weirdness. And they are also very useful, so that's a big plus.

Those high efficiency numbers are in lab conditions at ideal operating parameters. A lot of these high efficiency numbers come from test engines that are years away from being in use or are so exotic that they will never be used in a production car.

In the real world, car engines hardly ever operate at their maximum efficiency point. Add in idling, engine warm up time and the inability of conventional gas cars to recapture energy from regenerative braking and the actual efficiency is much lower.

Nothing like chemistry and physics to put a damper on a good conspiracy theory

>Generally mathematicians are not concerned about whether there are physical applications.

They're not anti-applications, it's more that they spend time in abstract-land for a while investigating something before they look for applications of what they just created. It's their creative process.

Haha I realise it's a silly question, I was more asking how it powers them, not if it does or not. I know it's not plugged into mains

I think this guy answered his own question. Gas only vehicles can only be so efficient... Thus the hybrid.

Much of the weight is driven by federally mandated safety standards

and who wants to buy a tin can where there is no coffee/phone holder or help keep your butt warm, comfort adds weight

Safety. Airbags, crumple zones, ect.

Because it's a full sized car now. The civic is larger than accords from a couple of generations ago

Lol I'm not arguing, I understand that. It's not plugged into mains so it has to be the engine, I'm just asking how.

FWIW the electric motor isn’t powered by the engine directly. That would be less efficient than the motor driving the wheels directly which is what they do.

It’s used for regenerative braking and then the battery power is used to run the motor.

What else is powering them?

Why the heck is a Honda accord 1500kg, that's nuts.
