Apple is rumored to be targeting 2020 to start production of the rumored Apple Car. That timeline, if at all accurate, could place the company in direct competition with aggressive electric car offerings from industry leaders GM and Tesla. Bloomberg cites unnamed sources:

The timeframe -- automakers typically spend five to seven years developing a car -- underscores the project's aggressive goals and could set the stage for a battle for customers with Tesla Motors Inc. and General Motors Co., both of which are targeting a 2017 release of an electric vehicle that can go more than 200 miles on a single charge and cost less than $40,000.

Recent reports indicate the company's team includes former executives from Ford, Tesla, and Mercedes-Benz.

Whether or not Apple is merely exploring the idea of automotive or is actively prototyping cars, one thing is clear — there'll be no lack of rumors for the next... 5 years.
