Simultaneous front wheel failure is highly unlikely?

“That’s completely false.”

“So for a discussion about efficiency, whether you’re in a place that uses more coal or uses more NG does not make a huge difference to the fact that BEVs have a huge efficiency advantage over conventional vehicles. Instead of being 4.5 times more efficient, it’s maybe *only* around 4 times more efficient.”

Correct, and that’s where it gets a bit confusing too. When talking about the VE for a FI engine, there are a couple ways to look at it. This first is looking strictly at the displaced volume vs trapped mass. For a FI engine running 1 atm of boost, this VE could be up to 200% because the boost is forcing twice the…

YEah, I should have used sarcasm font on the LS swap comment haha. But an electric e21 sounds really interesting so I say go for it!

Volumetric efficiency. Although engines have a very specific and easily measurable displacement, that doesn’t mean that volume of air can be ingested into the cylinder on every intake stroke. Restrictions in the intake system and through the valves reduce volumetric efficiency (VE), and valve timing has a strong…

That’s why I said they weren’t that much more efficient yet. When more electricity comes from renewable resources, electric vehicles have the potential to be orders of magnitude more efficient than ICE cars.

I already conceded that driving to a gas station will cause gas powered cars to drive out of their way, even if only slightly, but driving one mile out of the way with a 300 mile range car is only affecting efficiency by 0.3%. Yes that is a nonzero amount, but I’d consider it to be basically negligible.

I’m aware that gas doesn’t arrive at the pump with 100% efficiency, but neither does electricity arrive at your house. I’ll admit that I haven’t looked into the energy requirements for drilling/transporting/refining gasoline, but as I mentioned, 67% of US electricity comes from fossil fuels (mostly coal and natural…

“I believe driving an electric car and charging it on renewably generated electricity is better for the environment”

That number assumes that the electricity is generated with 100% efficiency...67% of electricity in the US comes from fossil fuels (https://www.eia.gov/tools/faqs/faq…), which are converted to electrical power with an efficiency of 35-40% (https://www.eia.gov/tools/faqs/faq…).

I actually did the math a while back on the model S and found that when you take into account the weighted average power generation efficiency for the U.S. grid, (from here: https://www.eia.gov/tools/faqs/faq… and https://www.eia.gov/tools/faqs/faq…) you get around 40-45 MPGe. That’s pretty good for a big, heavy, safe…

It actually doesn’t...

If you read the article it states that the driver took over manual control of the steering wheel and pressed the accelerator 10 seconds before the crash. 100% operator fault

Regarding the both videos (and the fatal accident as well), I think one of the main issues is that people don’t understand the purpose and capabilities of the sensors. Tesla states that Autopilot is not designed to be used with cross traffic. This makes me think that the range on the front radar sensor cannot detect…

Using “baja de” would change the meaning to “below/under California” instead of “lower California”

Sorry but the dynamic coefficient of friction is lower than the static coefficient of friction for tires on pavement. Locking the brakes will never stop the car faster than braking at the threshold of grip. The ABS computer doesn’t look at deceleration rate, it just looks at wheel speed sensors and tries to apply max…

Got pulled over wearing my “Led Footed” t-shirt a couple weeks ago...can confirm that it was not a good idea

I think the writers are really doing a huge injustice to Sabine, but I’m not sure your plan would come off any better. To me she seems like she’s actually a really funny person with interesting opinions that I’d like to hear about. In the old TG episode where she takes the van around the Nurburgring she’s witty,…

I’m pretty sure the road wasn’t clear, seeing as a Tesla managed to come by shortly after the truck began its turn...
