That's MSO, as in McLaren Special Operations.
McLaren has been quite vocal with its intentions to launch a new or updated car every year for the foreseeable future. It's a bold plan, and one that's only in its infancy. True to its word, for this year's Goodwood Festival of Speed, the UK supercar builder has revealed a bespoke version of its new 650S. With the help of McLaren Special Operations, the 650S MSO will be available as both a coupe and spider, of which just 50 examples will be built. So what makes it different from the base car?
The changes are entirely cosmetic, and were personally overseen by McLaren's chief designer, Frank Stephenson. The cars' exterior features additional carbon fiber styling and enhanced side blades. The rear bumper is now a three-piece unit with incorporated carbon fiber and there's a more aggressive diffuser. Just three exterior colors will be available: Papaya Spark, Agrigan Black, and Sarigan Quartz. All cars feature ten-spoke lightweight alloy wheels, which McLaren says saves almost nine pounds over the standard alloys. Deliveries will begin before the end of the year.
