Tesla is outselling the competition by miles. This chart shows how much catching up other automakers need to do.

• Tesla's competitors have a long way to go to catch up to Elon Musk's success. 
• Other electric car makers aren't selling nearly as many vehicles as Tesla. 
• Tesla has delivered the Model Y at several times the pace of rivals' EVs, says Motor Intelligence. 

Tesla has delivered the Model Y at several times the pace of rival automakers' electric vehicles — a sign these competitors have a long way to go to catch up to Tesla's success.

Tesla sold well over 200,000 Model Ys and more than 112,000 Model 3 EVs in the first half of the year, outpacing the next best-selling electric car, the Chevrolet Bolt, by over three times, according to data and estimates provided by Motor Intelligence. (Tesla numbers and others are estimates given some companies do not report each of their vehicles' individual sales numbers.)

Here's a look at the other top-selling EVs that Tesla has beat since the start of the year:

Even with these impressive numbers, Tesla has had an interesting several months. The automaker has been navigating a unique supply-and-demand issue and responding to it with a series of price cuts to its popular models. 

Tesla just blew delivery numbers out of the water for another consecutive quarter, but some still worry the EV market leader will have to make further moves to get inventory in the hands of customers. Many in the industry have also been anxiously awaiting a Tesla model refresh that's been a long time coming.

Still, Tesla's furthering its lead by taking a profit hit in pursuit of sales and signing deals with its competitors to allow their customers to charge at Tesla charging sites. Companies like Ford, GM, Rivian, and more have signed on in the hopes of giving their EV buyers a better ownership experience by using Elon Musk's network.

Meanwhile, those other automakers are racing to catch up on the production side. The legacy car companies have faced their own difficulties as they pour billions of dollars into electrifying their lineups, with inventory of some of their newest EVs stacking up amid high prices and high interest rates.

EV adoption in the US is growing, but there are still many challenges in the way for automakers, investors, and customers.
