The S-Class full-size luxury sedan has long been the face of class, sophistication, and cutting-edge technology for Mercedes-Benz. In the latest S-Class, this tradition continues with a coddling interior, a new V8 with more power and efficiency than before and enough gadgetry to put technophiles into a state of utter bliss.
For the latest model year, the S550 ditches its old, naturally aspirated 5.5-liter V8 in favor of a 4.7-liter V8. Despite its smaller displacement, the engine boasts 429 horsepower and 516 lb-ft of torque - far better than the old motor's 382 ponies and 391 lb-ft of twist - thanks to a pair of turbochargers. Fuel economy also improves from 14/21 mpg to 15/23 mpg.
The pricier S600 retains its 510 horsepower V12, which consumes fuel at the rate of 11 mpg in the city and 17 mpg on the highway according to the EPA. With a staggering 612 lb-ft of torque, the S600 will sprint from zero-to-60 in just 4.5 seconds.
Those looking for a more fuel-efficient S-Class should look into the S400 Hybrid and the diesel-powered S350 4MATIC BlueTEC, while power junkies will be delighted by the S63 AMG and S65 AMG models.
All S-Class variants recently received a mild refresh, with more of the more noticeable changes being the addition of daytime LED running lights fitted to the outer edges of the bi-xenon lamp units. The rear end is also accented with a total of 52 distinctively arranged LEDs in the two taillights. Gone are the body-colored strips through the taillamps.
Mercedes-Benz also makes more use of light as a styling element in the interior via the standard ambient lighting, now with a choice between three lighting moods: solar (amber), neutral (white) and polar (ice-blue).
Another change at the front of the car is a more pronounced arrow-shaped grille, plus a new front bumper with a light-catching contour and a chrome strip below the cooling air intakes. Exhaust tailpipes of all S-Class variants are now visibly integrated into the rear bumper. Mercedes-Benz says its engineers have also implemented specific aerodynamic measures to reduce wind noise.
Camera and radar-based driver assistance systems include Adaptive Highbeam Assist, Lane Keeping Assist and the Pre-Safe brake system linked to the proximity regulating radar, which intervenes autonomously before an impending rear-end collision. Other highlights include the Attention Assist driver drowsiness monitor and Active Body Control with automatic crosswind stabilization.
Engineers also managed to improve the night-vision system with the introduction of Night View Assist PLUS, which is equipped a special pedestrian detection function. The Pre-Safe braking system has also been improved to reduce injuries in unavoidable crashes. Mercedes says the car can apply maximum braking pressure automatically around 0.6 seconds before what is recognized as an unavoidable accident. The system therefore acts as something like an "electronic crumple zone," Mercedes contends.
Inside, the S-Class is as luxurious as ever.
