Understanding Tesla View of HP and Torque

 

Most people today understand when a person mentions Horsepower or Torque they relate it to how well a petro powered auto might perform. Faster, stronger, driving machines that compete for your hard earned dollars while giving you an in the gut experience to make one grin from ear to ear or puke depending on your own personal constitution.

 

With today's EV auto's, people are still looking to relate the EV to the horsepower and torque or HP / lb-ft that they are used to and no fully understanding that in the EV world the motors are dealing with Kilowatts and Megawatts which is the common terms used for electric motors converting electricity into motion.

 

In reviewing Tesla's Blog, I came across a posting by JB Straubel, Chief Technical Officer for Tesla. He wrote a blog titled "Tesla All Wheel Drive (Dual Motor) Power and Torque Specifications" in which he covers Electrical Horsepower, Dual versus single motor, and all wheel drive 85D and 70D covering the differences between the two.

 

One thing that I learned was that while we all know that petro auto's loose HP/Torque in higher elevations, all auto's have reduced air resistance, yet EV motors actually get faster. It is an insightful read especially about the ability to adjust their power between front and rear motor both going uphill and downhill where regenerative power capture takes place.

 

Take a look and sound off on what your thoughts are on his blog post.

You have to play to your strengths and instant Torque is it for Tesla. You have to give what you have as so many people consider about the things you don't have like the ability to refuel in a couple mins on the fly etc. 

 

EV cars have to be marketed differently no matter the brand because they are different. 

I think people are learning that performance is no longer golf cart like so they will have to come up with other ways to show advantages till they come with improved batteries and even faster charging. 

 

GM will market the Bolt unlike any other car they have had even the Volt.

      Tesla Semi starting off with a Bang, Can Tesla Deliver?
      Tesla in the last week has gone from zero to hero in regards to helping companies that have fleets of semi trucks potentially reduce their carbon footprint. 
      Anheuser-Busch started off with pre-ordering 40 of the Semi's. This was then followed by Sysco ordering 50 themselves. This week we now hear that PepsiCo has placed an order for 100 EV Semi's. Story is all the same, reduce costs of maintenance and fuel plus adding silence into their night / early morning deliveries. 
      Sysco being one of the largest food delivery companies along with Bud's order places it at $13.5 million in semi value. PepsiCo adds another $15 million so a total of $28.5 million. Then Wal-Mart places an order for 15 of the trucks for testing with a price of $2.25 million. DHL has also ordered 10 of the Semi's for testing in the US market so another $1.5 . J.B. Hunt and Ryder truck hauling lease companies have also placed large orders they say but have declined to say how many at this time for EV Semis. This brings in the last 2 weeks since the semi's introduction about 200 pre-orders of the trucks or about $30 million book value with an unknown amount from two of the biggest leasing truck companies.
      PepsiCo has 10,000 semi's alone on the roads of North America and has a goal to reduce greenhouse gas production on the road by 30% by 2030. Seems it could be even more trucks to be ordered to help them achieve this number. Over all, Tesla has had some game changing ideas, yet with the Tesla 3 mess of building the cars, one does have to wonder if Tesla can deliver and get these trucks to market by 2019.
      It seems that this has been good for Tesla stock as the more truck orders being placed has continued to push up the stock price.

      More than 90 percent of Tesla Model S and X models that roll off the assembly line require fixes before they are shipped. This figure comes from nine former and current Tesla employees that spoke to Reuters this week citing data from the company's internal tracking system.
      At Tesla “so much goes into rework after the car is done ... that’s where their money is being spent,” said a former supervisor.
      Industry experts say it is critical for an automaker to get the quality right before initial production as repairs waste time and money. Other automakers such as Toyota only have an average of "fewer than 10 percent of their cars" requiring some sort of fix.
      Some of this can be attributed to Tesla's pressure to keep the production line moving, even when there was some sort of issue. This caused certain batches of vehicles to not have various parts such as windshields or bumpers. The understanding according to the workers is they would be fixed later.
      Other issues such as doors not closing or missing trim pieces show Tesla is still struggling with getting the basics right.
      Defects included “doors not closing, material trim, missing parts, all kinds of stuff. Loose objects, water leaks, you name it,” another former supervisor said. “We’ve been building a Model S since 2012. How do we still have water leaks?”
      Tesla calls models with quality issues “kickbacks” and are either fixed on the production line or head to one of Tesla’s outdoor parking lots for repair. According to the workers, one of the lots "has exceeded 2,000 vehicles at times".
      “Our goal is to produce perfect cars for every customer. Therefore, we review every vehicle for even the smallest refinement. Most customers would never notice the work that is done post production, but we care about even a fraction of a millimeter body gap difference or a slight paint gloss texture. We then feed these improvements back to production in a pursuit of perfection,” Tesla said in a statement to Reuters.
      The company declined to provide any post-assembly defect rates and denied those repair lots exist.

      Tesla is known for building quick vehicles, but they're also known for burning through a lot of cash. Bloomberg recently crunched some numbers on how fast Tesla goes through money and the amount is quite shocking.
      According to their data, Tesla has been burning through $8,000 per minute (about $480,000 in an hour) for the past 12 months. At this rate, Bloomberg predicts that Tesla could run out of money by next August.
      Tesla spending money like it is going out of style is not all that surprising. The automaker is trying to ramp up production of the Model 3 along with dealing with various issues. Still, the $8,000 per minute figure gives us an idea of how far Tesla still has to go before exiting what it calls 'production hell'.
      Investors still are bullish on the electric car builder, with a share price of $317.81 at the close of trading yesterday. Tesla also has a market capitalization of more than $53 billion, beating the likes of Ford ($48 billion). The difference being is that Ford is able to consistently make a profit.
      Tesla says they have enough cash to meet its target of building 5,000 Model 3 sedans per week by the end of March, and expects to “generate significant cash flows from operating activities” afterward. The company is also reservations on their Roadster due in 2020* to help raise funds. Buyers will need to plop down $50,000 for the standard model or $250,000 for the Founders Edition. Tesla will only produce 1,000 models of the Founders Edition, meaning they could possibly produce $250 million in income. 
      “Whether they can last another 10 months or a year, he needs money, and quickly,” said Kevin Tynan, senior analyst with Bloomberg Intelligence. Tynan estimates that Tesla needs to raise $2 billion or more in capital by mid-2018 to stay afloat.
