2021 Mercedes-Benz S-Class S450 Auto 4MATIC

2021 Mercedes-Benz S-Class S450.

The 2021 Mercedes-Benz S450 is a large luxury sedan built around quietness, composure and a high level of cabin technology. As part of the W223-generation S-Class, it combines a 3.0-litre turbocharged petrol engine with an electric compressor and 48-volt mild-hybrid assistance, delivering a sophisticated powertrain matched to a nine-speed sports automatic transmission and 4MATIC all-wheel drive.

Its long, formal sedan profile is finished in Graphite Grey metallic paint and enhanced by AMG Line exterior styling, 20-inch AMG multi-spoke alloy wheels, privacy glass and a panoramic sliding sunroof. The sunroof brings additional light into the cabin while its power blind provides control over glare, and the dark-tinted rear glass adds a greater sense of separation for passengers. Practical touches include hands-free access to the boot, convenience boot-lid closing and a protective chrome loading sill.

Inside, the S450 uses a black leather interior with electrically adjustable front seats, memory settings, heating, ventilation and lumbar support. These features give the front occupants a broad range of adjustment for longer journeys, while the premium ambient lighting and black headliner contribute to a restrained, carefully finished atmosphere. Slate fine-grained poplar wood trim and AMG floor mats provide further distinction without overwhelming the cabin.

The technology suite is centred on Mercedes-Benz's MBUX system, with premium navigation, augmented-reality head-up display, a 3D digital instrument cluster and a large central screen. Smartphone integration includes Apple CarPlay and Android Auto, while wireless phone charging, digital radio and a premium sound system support everyday connectivity and entertainment. Gesture control, a fingerprint scanner and Mercedes-Benz connected services add alternative ways to interact with the vehicle's functions.

Ride comfort is supported by AIRMATIC semi-active air suspension, while rear-axle steering is designed to improve manoeuvrability at lower speeds and stability when travelling faster. The combination of air suspension, all-wheel drive and the 48-volt electrical system gives the S450 a technically advanced foundation suited to a flagship sedan. The vehicle also includes an AMG sport brake system and start-stop technology.

Driver assistance equipment is extensive. The listed Driving Assistance Package includes adaptive cruise control, active lane-keeping assistance, active lane-change assistance and road-sign recognition. Active Brake Assist, pedestrian protection, a 360-degree camera, active parking assistance and parking sensors provide additional support around traffic, manoeuvring and tight parking spaces. Keyless-GO access, automatic climate control, rear window roller blinds and a through-loading rear-seat system add convenience to the daily experience.
