Tesla's lackluster second-quarter sales may fuel some bearish arguments about its uniqueness, but the electric carmaker still has a clear advantage over its competitors, an analyst told CNBC on Tuesday.

James Albertine, senior automotive analyst at Consumer Edge Research, told CNBC's "Squawk Box" that over the next six months, Tesla has the potential to reap big rewards as the first of the highly anticipated Model 3 sedans begin to roll out.

He explained that Tesla's future demand was relatively solid, while other manufacturers were facing more uncertainties over who will be buying their vehicles in the near term. Last month auto sales fell 3 percent despite low unemployment, lower gas prices and higher consumer confidence.

"We're more optimistic. We think the Model 3, when you think about it, 400,000-plus standing orders for vehicles, and manufacturers all across the country (are) wondering who's in line for their vehicles," he said, adding, "(It's) Tesla with the clear advantage, in our view."

Last year, reports said Tesla received 400,000 pre-orders for Model 3, and the very first unit for delivery was set to be built later this week. It will be delivered with 29 others at the end of July. The vehicle is selling for $35,000, according to Tesla's website, which suggests a potential future sales value of about $14 billion.

But Albertine said there could still be some risk associated with the car-maker and its ability to meet deliveries, including those of the Model 3.
