You guys don’t understand electric propulsion. You can’t compare it to ice engines.
While the EV is always efficient the ICE engines masks its huge inefficient use of fuel by dividing its power into gears - which is greatly reflected by the loss of acceleration. It is as though you know it is happening but you refuse to understand it after all these years of shifting gears. Maybe it’s because I drive a manual. Lol.
If you added gears to a Tesla for more range it would have zero impact other than the extra weight. A taller gear would simply add more resistance and cause more electricity to be used at a lower rpm.
Perhaps the biggest benefit for the Porsche is that drive line components are less stressed with the lower gear off the line. But if you think it help speed or mileage you need to seriously hit the text books.
Of course it takes longer to charge for now but it you travel less than 250 miles at a time you actually spend less time fueling or driving to a gas station. If you have electricity at home. Lol. Some still think that this electric stuff will not ever make it to the home.
Perhaps you are the one not understanding
Do you know what a torque output curve of a electric motor looks like and the efficiency curve? They goes down the higher the rpm, as electric motors aren't efficient at high rpm, different than a normal engine where engine output rises with rpm. Normal car engines can't rev as high as electric motors, hence why they have gearboxes to reach the higher speed.
Tesla forgo a gearbox doesn't mean it's the correct way or only way to do things. Tesla omit the gearbox simply because they want to save money. For their performance target, especially for the North American market, the rpm range of their electric motor is good enough, they have no need to tap the upper echelon of the performance scale with a gearbox.
Porsche added a gearbox to the Taycan because they want to maintain efficiency at autobahn speed. If they had copied Tesla and skipped the gearbox, the electric motors will be forced to rotate at a highly inefficient rpm range on the autobahn. This is one reason why the Taycan outperform Tesla so much in Germany.
Say what you want about range and efficiency numbers manufacturers published. But in the real world, there are plenty of proofs published on YouTube and websites that states that a Taycan with the 2 speed gearbox isn't that far behind a Tesla on the highway range, exceeding the government rating while the Tesla struggled to even match it's government rating.
