The 2021 Mercedes-Maybach GLS 600 Is the Most Expensive American-Made Factory SUV

If you want the most expensive things Mercedes-Benz has to offer, you turn to Maybach. Though up until now, the marque’s exclusivity was limited as much by its available models as its high prices. That’s because, for the past few years, it’s only had 2 S-Class-based sedans. Now, though, it has an SUV, the 2021 Mercedes-Maybach GLS 600. But it’s not just the most expensive vehicle the German automaker offers. It’s also the most expensive American-made SUV on sale today.

How is the 2021 Mercedes-Maybach GLS 600 the most expensive American-made SUV?

Like the AMG GLS 63, the Mercedes-Maybach GLS 600 has a mild-hybrid-equipped 4.0-liter twin-turbo V8, Motor1 reports. The Maybach model, though, is slightly detuned. Normally, it has ‘just’ 550 hp and 538 lb-ft, though the starter-generator adds up to 21 hp and 184 lb-ft during acceleration. Still, with standard AWD and a 9-speed automatic, this luxurious bus can go 0-60 mph in 4.8 seconds, Car and Driver reports.

The rear passengers get a 7” personal tablet and a wooden parcel shelf separating them from the rear cargo area. Speaking of wood, all the wood in the trim has been aged at least 10 years, The Drive reports. Buyers can choose between a 3-seat 2nd row or dual rear captain’s chairs, and spec a refrigerated storage compartment with champagne flute holders. There’s no 3rd-row option, though.

Besides powering the starter-generator, the 48-volt mild-hybrid system is also linked to the GLS 600’s ‘E-Active Body Control,’ Autoblog reports. The crossover scans the road ahead and adjusts the air suspension in preparation for bumps, imperfections, and oncoming corners. And it means that the Mercedes-Maybach GLS 600 can bounce. Plus, the air suspension automatically raises and lowers for easy entry and egress, further assisted by powered running boards.

What’s the competition like?

The 2021 Mercedes-Maybach GLS 600 should hit dealerships later in 2020. And when it does, it will have some rivals.
