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's production hell seems to be only getting worse than better. Various issues at their Freemont plant has caused the automaker to push back their goal of producing 5,000 Model 3s from late last year to June of this year. This, in turn, has caused some holders of Model 3 reservations to have their order pushed back to 2019.
      “As we work hard to meet demand, we wanted to let you know that your estimated delivery timing has been adjusted to a slightly later window,” Tesla said in an email to customers.
      According to Bloomberg, the new date depends on when the reservation was placed and what model was chosen. Tesla is trying to get the more expensive long-range battery model out first before starting production of the cheaper standard battery model. This has buyers of the latter model worried as they might not get the full $7,500 tax credit. The credit begins to phase out once an automaker has built 200,000, something Tesla expects to hit sometime this year.
      The move has caused some reservation holders to take to various forums and Twitter to complain. Others are deciding to jump ship and buy a Chevrolet Bolt. Reuters reports that Chevrolet dealers in California are seeing a noticeable increase of Tesla shoppers interested in the Bolt.
      “We’re getting the Tesla people who wanted their Model 3. We ask them, ‘What other cars are you interested in?’ They’re mostly Tesla. But they want the car now. They don’t want to wait,” said Yev Kaplinskiy of Stewart Chevrolet.
      Kaplinskiy said they sold 15 Bolts last weekend.
      Chevrolet is taking advantage of the delay by emailing some prospective buyers this week with the message of, “Bolt EV: Now available.”

      Tesla Wagon production has begun in UK.

      Start with a Model S P90 and deconstruct the rear, add a carbon fiber rear addition and lift gate and you have the Tesla Wagon that went from a 26.3 cubic feet of interior space to an SUV-like 33.7 cubic feet, that is 7.4 additional cubic feet of space. This enhanced Wagon added a total of 26 pounds to the finished weight and is still faster than the Mercedes-benz AMG E63 wagon.
      This whole project came about by a guy who got his Tesla S and then realized his Four legged friends could not be in the far back comfortably. What you end up with is a new company called QWESTNORFOLK and they are now taking real orders for people who want a feature rich EV 4 door wagon.
      According to the interview that was done by Hybrid Cars, (web site) This was all done use established auto part suppliers in Europe meaning that
      there glass, rear window wiper, electrical bits, etc. can be easily obtained.
      Everyone is writting about it this week but the auto is here is functional now. 
      Wonder how many will actually get built? Europe does like their wagons and EVs and this is both.
