During our drive, we were able to experience a well-equipped EQE SUV 350 4Matic and a 500 4Matic. Acceleration in both, like most EVs, is instantaneous and should satisfy most drivers. Mercedes estimates the 350 4Matic will accelerate from 0 to 60 mph in 6.2 seconds and the 500 4Matic in 4.6 seconds. While neither figure is slow, the EQE SUV 350 4Matic would be almost a second behind a gas-powered GLE 450. The 500 4Matic will be closest to keeping up with the BMW's iX xDrive50, which in our testing zipped from 0 to 60 mph in 4.2 seconds.
What impressed us more was the manner in which the EQE SUV decelerates. Utilizing the paddles behind the steering wheel, you can engage three levels of brake regeneration (where the vehicle uses the motors to charge the battery when decelerating) and easily find one to suit your preference. Normal regeneration mode is good for a majority of the populace, while Aggressive regeneration will feel more natural for EV drivers who desire a one-pedal-drive sensation.
The third regeneration mode — Intelligent — is eye-opening. It utilizes a combination of map and sensor data to calculate when and where to use an appropriate amount of brake regeneration to slow the vehicle automatically. We've only driven the EQE SUV briefly but found there were instances in this mode where it began to brake early to charge the battery and slow the vehicle naturally. We highly recommend that you still brake naturally to assist it. It was just impressive in the way that it approached the regeneration process.
One efficiency breakthrough Mercedes has added to the EQE SUV relates to the 4Matic (all-wheel-drive) system when in Comfort or Eco drive mode. Upon initial acceleration, both front and rear electric motors engage to propel the vehicle forward. Then at some point when you're cruising along at highway speeds, the front motor decouples (disengages from the front driveshaft) and the 4Matic EQE SUV becomes a rear-wheel-drive vehicle to maximize the range. By disengaging the front motor, it removes the parasitic draw on range that would occur in a typical all-wheel-drive system. Once you start slowing down, or have a need for more power, the system will automatically re-engage the front motor.
The EQE SUV's ride is smooth like butter thanks to the available adjustable air suspension. It's also a capable handler. While it's a midsize EV SUV, its agility makes it feel more like a compact SUV. It will please sporty drivers in the way that it navigates through curvy roads — especially on models equipped with the rear-wheel steering system that can turn the rear wheels up to 10 degrees. That system also makes U-turns a breeze.
