Mercedes-Benz freshened SL-class roadster hides new driving dynamics tech (pictures)

LOS ANGELES -- The SL-class is Mercedes-Benz's top-of-the-line roadster, a two-seater with a retractable hard top.

The SL550 model comes with a 4.6-liter V-8, using twin turbochargers to produce 449 horsepower, while the new SL450 version will come with a 3-liter turbocharged V-6, good for 362 horsepower.

As one of Mercedes-Benz's sport models, the SL-class gets a single bar grille. New for 2017 are LED headlights.

An adaptive suspension includes five settings, ranging from sport to comfort, changing the ride quality at the touch of a button in this rear-wheel-drive car.

Mercedes-Benz's Active Body Control actually tilts the car laterally in a turn, producing a banked effect to keep passengers comfortable where inertial forces might push them to the sides.

Mercedes-Benz has been a pioneer in driver-assistance features, and offers the new SL-class with its adaptive cruise control, capable of managing braking and speed in stop-and-go traffic, and Traffic Jam Assist, which can control steering in low-speed situations.

The SL-class' retractable top automatically folds into the trunk, yet leaves space for a couple of small suitcases.

Mercedes-Benz Air Scarf blows warm air from the headrests onto occupant's necks.

The cabin electronics seemed to have missed an upgrade in this new SL-class, but this system will support Apple CarPlay, giving iPhone users solid connected features.

A Bang & Olufsen audio system includes these acoustic lenses positioned at the A-pillars, improving frequency response.

As one of Mercedes-Benz's sport models, the drive selector for its nine-speed automatic transmission sits on the console, rather than being a stalk on the steering wheel.
