S65

S65 is a designation used in different contexts to refer to distinct products and terms. In safety labeling, it appears as an EU safety phrase; in automotive engineering, it designates two high-performance powertrains used in distinct models from BMW and Mercedes-Benz.

In European Union safety labeling, S65 is one of the S-phrases. The standard text for S65 is: If swallowed, seek medical advice immediately and show this container or label. These phrases are used on chemical product packaging to communicate urgent medical guidance and are part of a system intended to reduce risks from potentially harmful substances.

In automotive engineering, S65 refers to two notable power units. The BMW S65 is a high-revving 4.0-liter V8 engine developed by BMW M GmbH. It was used in the E9x M3 family from 2007 to 2013, succeeding the earlier V8 in the M3 lineage. The S65 is known for its high-rev performance, delivering roughly 414 horsepower and revving beyond 8,000 rpm, contributing to the M3’s distinctive sporting character.

The Mercedes-Benz S65 AMG is the high-performance variant of the S-Class produced by Mercedes-AMG. It employs a large 6.0-liter V12 twin-turbo engine and is configured to blend luxury with substantial straight-line acceleration. The S65 AMG models were introduced in the late 2000s and continued through the mid-2010s, serving as flagship performance sedans within the S-Class lineup during that period.

The term S65 thus has multiple meanings, depending on the domain, ranging from safety labeling to high-performance automotive engineering.
