The S320 has a unique place in Mercedes Benz's line-up of vehicles as it was built on the largest chassis Mercedes-Benz built at the time yet it was powered by a six-cylinder engine. The S320 sedan was on the W140 platform and was produced between model years 1993 and 1999.


The S320 was powered by a 3.2-litre V6 engine. This 24-valve, dual-overhead-cam motor had a 3.54-inch bore, a 3.30-inch stroke and a compression ratio of 10 to 1. Power output for this engine was 228 horsepower at 5,600rpm and 232ft.-lbs. of torque at 3,750rpm.

Exterior Dimensions

The S320 sedan was offered in both short-wheelbase and long-wheelbase variants. The short-wheelbase S320 rode on a 119.2-inch wheelbase and had an overall length of 201.3 inches. The long-wheelbase S320's wheelbase measured 123.6 inches; its body length was 205.2 inches. Both variants sat 58.5 inches tall with body width of 74.3 inches.

Interior Dimensions

The interior dimensions of the S320's cabin remained the same between short and long-wheelbase models for the driver and front passenger, but the rear part of the long-wheelbase cabin saw gains in space. Front headroom measured 38 inches and front legroom measured 41.3 inches. The shorter S320 model featured 37.8 inches of rear headroom and 36.1 inches of rear legroom. The long-wheelbase model gained 0.7 inch of rear headroom and 3.5 inches of rear legroom.
