Mercedes unveils buzzy long-range electric sedan

• And as CNN notes, that's also further than a Toyota Prius hybrid can travel on a full tank of gasoline.
• Mercedes revealed the Vision EQXX in a virtual presentation for the CES tech show in Las Vegas.

Yes, but: It's a concept, not a product. Mercedes calls it a "technology blueprint for series production." (Car and Driver calls it "production-viable, although not production-intended.")

The intrigue: Mercedes says the range is achieved not through brute force, but via efficiency gains that make the battery more energy-dense.

• The battery takes up 50% less space and weighs 30% less than batteries with "comparable capacity," they claim.
• It uses less than 10 kilowatt-hours per 62 miles of travel, Mercedes said, though it's citing digital simulations.

The big picture: It's part of Mercedes' wider push into EVs, with plans to invest over $45 billion through 2030.

• Motor Trend frames the Vision EQXX concept as a legacy automaker fighting the EV startups, noting "the establishment strikes back."
