Mercedes unveils luxury electrical vehicle for U.S. market

What we don't know: The price. I guess we know it won't be cheap. Here's the Associated Press...

• "The EQS is the sibling to the company’s S-Class large internal-combustion sedan, the luxury brands flagship model that sells for $110,000 and up."
• "The two cars aim at the same upper end of the market, though the EQS is set apart by being [built] on the company’s electric-vehicle architecture, or EVA."

How it works: "Sporting what the automaker claims is the world's lowest drag coefficient (0.20) and the world's largest in-car screen (56 inches), and making as much as 516 horsepower, the EQS ... aims to put the Mercedes stamp on the electric-vehicle segment by starting at the top," Car and Driver reports.

What we're watching: The EPA-estimated range of the models sold in the U.S.

• That's still unknown, but The Verge's detailed and photo-rich coverage points out that European testing shows 478 miles, though that will "most likely drop" in EPA tests.
