Eh, range is not eff. Range is range, a 8.2 MPG 454 gets good range with a 60 gal dual tank setup.

 

In an EV efficiency = range. Its not like a gas car.

 

Weight is the enemy of range and efficiency regardless of propulsion type. Should be obvious.

 

No it is exactly the same, just make the pack bigger. Issue is that batteries have pathetic energy density and scaling

 

LOL, it doesn't work like that. Adding size to the pack dramatically increases vehicle size, cost, weight and time to charge. Its not like just increasing the size of a gas tank.

Thats why yes, people who spend $100k on an EV care about efficiency because that gives them the longest range and the shortest charge times.

Size of the gas tank also has a point where it can't get any bigger. In my S580 for instance I love the 30 MPG on the highway not for the cost savings but for the 600 miles of range.

 

True, energy density of gasoline is many factors beyond batteries which obviously means they don't scale the same.

 

As SW said, it doesn't work like that with EV'S. If you want to get better range, you need better efficiency. Using the Cyber Truck as an example, it has a smaller battery pack, yet gets better range. 125 kWh vs 200 kWh battery pack for the Hummer. The goal is to make them more efficient, without losing performance so you don't need such a big battery pack.

As far as the Hummer goes, my brother in law wouldn't be using for travel anyways. It would be his big *** toy

 

Hummer EV just continued the tradition of being the least efficient vehicle you could buy.

 

Well, increasing the size of a gas tank also adds weight, although not by a huge amount. The tank itself weighs more, and the extra gas that goes into it weighs about six pounds per gallon.

 

It definitely wasn't built for the average Joe 🤣

 

That's because gasoline is more energy dense than batteries. One gallon is equal to 33.7 kWh. On one gallon of gas both my Tesla's can go about 120 miles

 

Yep, thats really what Tesla shines at, the engineering is unmatched when it comes to weight vs range.

Its not as dramatic a difference though. A gallon of gas increases weight 6 lbs but an equivalent size battery increase probably increases weight 30 lbs.

 

That means if a Tesla S Plaid replaced the battery with a gas tank it would have 3,000 hp and go 0-60 in 0.9 seconds
/bad math

 

I think both the Cybertruck and Hummer EV are rated at over 300 miles of range.

If I'm reading correctly, the Cybertruck has a battery capacity of 123 kWh whereas the Hummer EV has 170 kWh or 205 kWh.

So I do read that to be that the Hummer achieves similar range as the Cybertruck but via a huge battery, rather than efficiency.

 

Yes, Hummer does it with a bigger battery pack. The goal is smaller battery packs and less weight.

But like the Honey badger, Hummer doesn't give a s h i t about efficiency
