Motley Fool has assembled this chart, which shows projected Tesla annual sales volume worldwide.

As the chart clearly shows, Tesla sales will explode once Gen 3 hits the market.  Few dispute this looming sales explosion.

What we're not so sure of is the timeline.  We predict Gen 3 won't launch until late 2017 or early 2018.  Gen 3 derivatives (convertible, crossover, sports car) likely won't arrive until the Tesla Model S gets its redesign.  Missing from the chart in the second-generation Tesla Roadster, which we think will arrive in 2022.

The specifics of the chart don't matter all that much.  We're inclined to agree that as long as Gen 3 arrives by 2018 or so at the price point that's been promised ($40,000-ish), then 500,000 units sold in 2020 seems achievable to us.  Sure, it's a lofty mark and a long ways off, but if anyone can do it, it's Tesla who will get it done.
