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.

      A fresh stack of spy photos of the upcoming Hyundai Veloster N have made their way on to the web this week. The photos show the mule losing some of the camo that we have seen in previous spy shots and are able to pull some new details. The most apparent item is a new rear wing mounted the roof. We can also make out a set of large tailpipes and the front grille extending towards the bottom of the bumper, possibly hinting that there is an intercooler hiding behind it.
      We also got an idea of what is in store for the standard Veloster. Hyundai has decided to drop the split-window liftgate of the current model and go for a regular hatchback. We also note there is coupe-like styling for the roofline.
      The Veloster N will be the second model from Hyundai's new N performance lineup and the first N model to arrive in the U.S. It is expected that the Veloster N will share the powertrain found in the i30 N - a turbocharged 2.0L four-cylinder 246 horsepower. A performance package bumps power to 270.

      When Tesla finally revealed the Model 3 a couple weeks, we learned about a number of items such as max range (220 or 310 if you opt for the larger battery), how fast they hit 60 mph, and what will come standard. What wasn't talked about was how big the battery was and power figures. Thanks to some EPA documents, we have some idea on both.
      InsideEVs found some preliminary documents dealing with the long-range Model 3 and figured out that has an 80.5-kilowatt-hour battery pack - the document says it is a 230 Ah battery pack with 350 V nominal voltage. We should note that CEO Elon Musk has said previously that the Model 3 could not take anything larger than a 75-kWh battery. But, InsideEVs says Musk could have been referring to useable, not the max capacity of the pack.
      We also have learned that the long-range Model 3 produces 258 horsepower. Sadly, no torque figure was given in the documents.

      Tesla CEO Elon Musk made a surprise announcement earlier this year with the upcoming Model Y crossover using a new platform and not the one used for the Model 3. Musk has changed his tune, however.
      “Upon the council of my executive team . . . who reeled me back from the cliffs of insanity—much appreciated—the Model Y will in fact be using substantial carryover from Model 3 in order to bring it to market faster,” said Musk during the second quarter earnings call yesterday.
      How much faster? Previously, Musk said the Model Y (if that is the final name) could arrive by 2019. But during this call, Musk did not give a date - possibly a wise idea.
