Tesla Is Starting a Certified Preowned Program
cartechboy writes Most luxury automakers have a Certified Previously Owned (CPO) program. Tesla isn't like a normal luxury automakers, in fact, it's not really like any automaker out there. It doesn't have franchises and it sells its own vehicles through its network of galleries. Now, it plans to create its own CPO program. There are a great deal of Model S sedans out there currently under lease contracts. When those cars are ready to come back, Tesla has guaranteed that it will purchase them for a figure that falls somewhere between 43 and 50 percent of the original purchase price. This is exactly how Tesla's going to create its CPO fleet. Tesla seems to do everything in an unconventional manner, so we'll have to see if its CPO program behaves like every other automaker's, or if it's different somehow as well.
Powerplants of every kind take a certain amount of mass, and as they rotate they induce a certain amount of vibration.
Wrong: a free spinning wheel creates no vibration.
Combustion engines create a lot of vibration by their very design with a crankshaft and four strokes pistons. Have you been on an electric car? the reduced vibration is notable. Other readers might have been on a dual diesel/electric train while traveling in Europe? One can tell when they switch to the diesel power plant on the station at the end of the electric line because of the increase in carriage vibration.
