Mercedes-Benz GLE gains power, efficiency in wider model range (pictures)

Mercedes-Benz enacted a name change for many of its models last year, updating its old ML five passenger SUV with a GLE name plate.

At the New York auto show, Mercedes-Benz showed more than just a name change, giving the newly christened GLE new drivetrains and performance technology.

The Mercedes-AMG GLE63 is a new high-performance version in the GLE line.

As per Mercedes-AMG styling, this model gets a single-bar grille.

Mercedes-Benz's 4Matic all-wheel-drive system comes standard on the GLE63.

An air suspension can increase ground clearance, but can also stiffen the suspension for better handling.

Mercedes-AMG fits the GLE63 with a 5.5-liter V-8 engine using twin turbochargers, one for each bank of cylinders.

Output from the GLE63's twin turbo V-8 is rated at 550 horsepower and 516 pound-feet of torque, while a GLE63 S version increases output to 577 horsepower and 561 pound-feet or torque.

A system called Active Curve uses the GLE63's stabilizer bars to counteract roll in the turns and keep the tires in full contact with the pavement.

An LED headlight system will be available.

The 21-inch wheels suit the proportions of the GLE63.

In the cabin, the Mercedes-Benz Comand interface includes this ergonomic touch controller for navigation, stereo and phone systems.

A dial next to the Comand controller lets you choose drive settings, affecting suspension and engine response.

As a high-trim model, the cabin features many material options, such as leather, carbon fiber and aluminum.

Sport seats feature the AMG logo.

The speedometer goes up to 200 mph.

Rear-seat passengers can enjoy individual entertainment screens.

Carbon fiber trim surrounds Mercedes-Benz's traditional door-mounted seat controls.

A flat-bottom steering wheel emphasizes the GL63's sport focus.

The Mercedes-AMG GLE63 joins a very small set of high-performance SUVs when it hits the market.

As another option in Mercedes-Benz's GLE lineup, the GLE550e provides a sweet spot of power and efficiency.

The GLE550e is a plug-in hybrid, adding electric propulsion to its twin turbocharged 3-liter V-6.

Mercedes-Benz rates the output from the GLE550e's drivetrain at 436 horsepower and 479 pound-feet of torque. The GLE550e is also capable of driving under electric power alone, with a stated range of 18.6 miles.

The GLE550e comes standard with all-wheel drive, called 4Matic by Mercedes-Benz. The gasoline filler sits at its usual place on the right rear fender, while a charging port for the batter is mounted on the left corner of the bumper.

Wood trim and quilted upholstery adorn the cabin, emphasizing Mercedes-Benz's luxury side.

Mercedes-Benz's cabin electronics include the center screen with navigation, app integration, stereo and hands-free phone system.

The center screen can show a power flow animation, a real-time schematic of engine and battery output.

The driver can choose Comfort, Sport and Snow settings with this center dial.

An 8.5-kilowatt lithium ion battery pack intrudes into the cargo area, raising the load floor by about 6 inches.
