Interesting article that touches on what makes Tesla so different from legacy brands...

"Even though Tesla’s 100-kWh battery pack is the biggest in the industry, it contains only as much energy as three gallons of gasoline."
I find this surprising.
And bare in mind a fully charged 100kWh Tesla pack can power an average UK house hold for 5 days solid!!I find this surprising.
Really shows you how much energy we are wasting burning petrol/diesel for personal transportation.
It's basically saying that Tesla cars are very efficient... But not as efficient as "legacy" manufacturers like Hyundai who hold the current title for most efficient EV. So basically it's BS.
Of course this efficiency comes at a price. The Model 3 is tiny, really really low like a 70s throwback where you have to swing right down to get in and out. That didn't really help Tesla's range performance though - Hyundai and Kia can make bigger, more comfortable cars that have better range just because they put a larger battery in, and they cost less too.

The Kona and Enero are also very slow with a low top speed, Tesla have no doubt made some compromises to make the model 3 bat st crazy fast Of course this efficiency comes at a price.

The EPA is also rating the M3 SR+ as the most efficient EV atm

I effectively DOUBLED my electricity consumption by getting the 100D.
I knew this beforehand, and was surprised at the amount of energy we actually use getting from A to B compared to powering our home. Puts "we need LED lights" in a new perspective.

A US gallon of gasoline contains the equivalent of 33.41 kwh of energy on average, so a 100 KWh battery indeed contains just about 3 (US) gallons' worth of energy...
Really points out just how efficient EV powertrains are, and how INefficient ICE powertrains are...
fair point - however 're-fueling' is one area where ICE power-trains have EV's lickedReally points out just how efficient EV powertrains are, and how INefficient ICE powertrains are...

That's the second time this particular BS has been posted here. Here are the actual facts, which show that even for a much less powerful vehicle H/K are far behind:

One thing I dont think many traditional car makers understand is that any even minor efficiency gains make a huge difference with EVs.
They understand the relationship very well, an EV drivetrain is easy to model compared to the more complex hybrid architectures most of the OEMs are already experts in. Where the casual observer's view of an OEM's apparent understanding is skewed, is in the subtleties of attribute trade-offs made by OEMs to make an all-round better** car at the expense of potential overall range or efficiency.- Better being hugely subjective of course. But the established OEMs all have decades of market data supporting their view of what "better" is and what attribute trade-offs customers typically like. This is where the early adopters skew things massively of course, as they are not typical customers.

a 100-watt light bulb operating for ten hours would use one kilowatt-hour so a 100kwh battery should power a 100w light bulb for 1000 hours 3 bulbs would be 333 hours or so.... so your not using less energy in your car than those three bulbs, your using a lot more.
300 watts for an hour is only 0.3 kWh

I used to have 3 100 watt lights in my living room before going LED, blows my mind that I can commute in and out of London with a peak speed of hmm 70mph down the mway and use less energy than those 3 light bulbs used !!!
Range of approx 300 miles, 75kwh battery, approx 17 kw average power at 70 mph? So 170 bulbs. Dave Hedgehog said:

I think you missed something in a calculation.A Tesla will usually do < 200Wh/km or take 300Wh/mi for easy calculation.
That means that your 3 light bulbs have to be on for an hour to travel 1 mile.
And that's in an EV with class leading economy.
