Mercedes-Benz S-Class 1985–1991 car dimensions: 5020 mm long, 1820 mm wide and 1437 mm high. Unladen weight is 1,570 kg. Braked towing is 1,900 kg.
The cabin focuses on comfort with biomechanical seats that support long drives and reduce fatigue. Automatic climate control keeps the interior temperature steady with fresh air exchange every 20 seconds and multiple vents including for rear passengers. Electronic cruise control is easy to use and resumes speed after braking. Power seats with memory and heated options appear on higher models. Driver airbag and ABS became available or standard mid-generation for added safety. No modern electronics like screens or advanced alerts.
The boot holds 505 litres with a high lid and practical shape for luggage. Rear seats do not fold so space stays fixed.
Towing is possible with factory hitch options rated up to 1900 kg braked and 750 kg unbraked. Payload sits around 520 kg depending on model weight. Self-levelling rear suspension on some versions helps with loads but is not a heavy-duty setup for work.
Seats form a biomechanical support system with five padded layers over a steel spring core tuned to the suspension. This cradles the body and lessens fatigue on long trips. Front seats are electrically adjustable in most models via door-panel controls, with two-setting memory and power headrests on higher grades. Flagship models add power adjustment and heating to the rear seats. Automatic climate control holds a set temperature year-round and fully exchanges cabin air every 20 seconds through 13 outlets, including a rear console.
ABS standard on 1985 models
Driver airbag standard on flagship models from 1985 and across the range later
Passenger cell withstands offset crash to 55 km/h
Four-wheel power disc brakes with ventilated fronts
Seat-belt tensioners available
Engines use fuel injection. Alloy V8 blocks and turbo-diesel designs cut weight and improve efficiency over prior models while keeping strong output. Taller axle ratios on diesels further aid economy on the highway.
The car is built for durability with refined maintenance procedures. Independent suspension, dual-chamber gas shocks and progressive power steering keep the ride controlled. Owners report high mileage capability when fluids and timing components are kept current.
Safety centers on a rigid passenger cell, crumple zones and overlapping doors that stay operable after impact. ABS prevents lock-up and keeps the car steerable in hard stops. Airbags and belt tensioners add restraint protection on equipped cars.
Living with the car means quiet cabin sealing, automatic climate that also warms the door panels, and optional electric sunroof. Regular care of the climate system, brakes and suspension preserves the original comfort and control.
