Tesla is a very good example of making good PR without anything specific new. They say, that they offer a performance package for an old model. But what is the real truth behind? 1. Improved battery performance: Everybody knows that batteries degrade over time. Batteries have to be replaced after some time. Batteries have a memory effect including Lithium Ion, even when the industry wants to tell a different story. Tesla is still offering replacement batteries for the Roadster. Because, if they would not, they would have a marketing problem. Tesla now decided to source the new cells in those battery packs. Which is a normal business decision, because the original battery pack was engineered at 2005/2006. That is almost 10 years ago. As such it is a normal business decision to source the new cells instead of sourcing the old cells with lower demand (increased prices). Reminder: any carmaker supports their car models >10 years. 2. Improved tires: Tires are improving year by year. The tires are not from Tesla. They are sourced from Godyear, Pirelli, Conti, or alike. I have to replace my tires every 3 to 4 years as they are loosing their condition and are not fit for the roads anymore. Of course, I always choose the latest the version with the latest technology. That is a thing of ongoing business. 3. improved body (CW): That is something you normally buy from some third party supplier, like AMG or Brabus for Mercedes, Alpine for BMW, … There is no such thing for Tesla, so Tesla made it himself.
