Going after the Porsche 911 like Daimler has with the Mercedes-AMG GT has required not only a proliferation of variants, but a steady stream of updates. And that's just what it has rolled out at the LA Auto Show.

While the new GT R Pro has drawn the lion's share of attention, Mercedes also applied a smattering of other enhancements to the rest of the models in its flagship sports-car line. And while most of those are electronic, there are some subtle visual modifications as well. Like the new LED headlights drawn from those on the new four-door coupe variant.

The lighting elements are further set back into their housings, with a tri-functional arched light array that integrates the daytime running nights, navigation lights, and turn signals. The rear bumper has been restyled as well with a new diffuser design, and there's an array of new wheel options.

Inside Mercedes has also fitted a new flat-bottomed steering wheel, display buttons in a stylized V8 design on the center console, and a fully digital, 12.3-inch instrument display. There's new settings for the AMG Dynamics system as well, and a standard AMG Track Pace telematics system for logging lap times.

Gone for the 2020 model year, though, is the lower/mid-level GT S variant. That version has until now offered 515 horsepower and 495 lb-ft of torque to split the difference between the base AMG GT (with 469 hp and 465 lb-ft) and the AMG GT C (with 550 hp and 502 lb-ft), all below the GT R (with 577 hp and 516 lb-ft). But we doubt that version will be missed much, especially now that the GT R Pro has arrived with a stiffer suspension, more aggressive aero, and further use of carbon fiber.
