Mercedes updates the S-Class flagship sedan

Mercedes has given the S‑Class a broad mid-cycle refresh that replaces or upgrades roughly 2,700 parts and introduces a revised 4.0‑liter V8 with mild‑hybrid support. The update also adds expanded rear-seat amenities and an updated MBUX voice assistant with short‑term memory.

Mercedes-Benz has issued a broad mid-cycle refresh for its flagship S‑Class as the company marks 140 years since Karl Benz's early patent. The update aims to advance performance, refinement, and in-car technology while preparing the model to remain central to Mercedes’ lineup through the decade. Changes touch many areas of the car, from powertrains and chassis hardware to interior comfort and digital services. The refresh is part of a wider product programme that includes dozens of new or updated models through 2027. Notable updates: - About 2,700 parts are reported as replaced or upgraded across technology, equipment, chassis, and powertrains. - The S 580 4Matic’s 4.0‑liter twin‑turbo V8 now uses a 48‑volt mild‑hybrid system and is quoted at 530 horsepower and 553 lb‑ft of torque, with a low‑4‑second 0–62 mph time in some specifications. - The six‑cylinder S 500 remains around 442 horsepower with higher torque and a short‑term over‑torque function; the S 580 e plug‑in hybrid is noted in some markets at about 100 km (around 62 miles) of electric range and roughly 576 horsepower combined. - Rear-seat appointments are expanded with larger 13.1‑inch displays, smartphone‑style remotes, fast wireless charging, a refrigerator, heated/cooled cupholders, HD cameras for video calls, and fold‑out tables. - Chassis and driving aids include suspension pre‑conditioning using road‑surface data shared via the cloud and rear‑wheel steering that is standard up to 4.5 degrees or optional up to 10 degrees to reduce the turning circle. - Exterior and lighting changes include a 20 percent larger grille with illuminated three‑dimensional stars, a lighting hood emblem, and new microLED headlights with an extended high beam reach. - The updated MBUX system adds an AI assistant that can draw on ChatGPT‑4o and other search/assistant services in some markets, with improved conversational memory; Mercedes has also restored more physical controls on the steering wheel. Summary: The refresh aims to keep the S‑Class competitive by blending mechanical updates, enhanced rear‑seat luxury, and more capable in‑car software. Mercedes expects a next‑generation S‑Class later this decade and plans roughly three dozen new or updated models through the end of 2027 as part of its broader product rollout.
