Yes, a Drifting SUV Is Real Now

There is something inherently absurd about a five-thousand-pound luxury SUV sliding sideways through a corner with smoke pouring from its rear tires. Mercedes-AMG knows this. The engineers in Affalterbach know this. And yet they have built exactly that capability into the latest AMG GLE 63 S, complete with a dedicated drift mode accessible through the drive mode selector. After spending a day with the system on a closed circuit, the most surprising revelation is not that it exists but that it actually works brilliantly.

The drift mode feature is part of a broader dynamics update to the 2026 AMG GLE 63 S, which also includes recalibrated adaptive dampers, a revised rear-axle steering system, and updated software for the AMG Performance 4MATIC+ all-wheel-drive system. But the drift mode is the headline feature, and Mercedes knows it will generate conversation, which is precisely the point.

How the System Works

Activating drift mode requires a deliberate sequence of inputs that prevents accidental engagement. The driver must first select Race mode through the AMG Dynamic Select controller, then press and hold the ESP button for three seconds, and finally confirm the selection through a prompt on the central infotainment display. Once activated, the system fundamentally reconfigures the vehicle's powertrain and chassis behavior.

In drift mode, the AMG Performance 4MATIC+ system decouples the front axle entirely, sending 100 percent of the engine's output to the rear wheels through the electronically controlled limited-slip differential. The stability control system does not switch off completely. Instead, it moves to a highly permissive setting that allows sustained oversteer while maintaining a safety net that prevents the car from spinning completely.

The Technical Details

  • Power delivery: The twin-turbocharged 4.0-liter V8 produces 603 horsepower and 627 pound-feet of torque, all routed to the rear axle in drift mode.
  • Differential behavior: The electronic limited-slip differential locks aggressively to maintain rotation during sustained slides, distributing torque between the left and right rear wheels based on steering angle and yaw rate.
  • Throttle mapping: The throttle response is recalibrated for more linear delivery, making it easier to modulate power mid-drift rather than dealing with an aggressive on-off characteristic.
  • Steering calibration: The rear-axle steering system locks in a neutral position to provide more predictable rotation characteristics during oversteer conditions.
