Mercedes-Benz
SLR McLaren 722 Edition (Coupé)

Why it matters

The 722 Edition was the sportier SLR McLaren coupé, named after the number carried by Stirling Moss and Denis Jenkinson's 300 SLR in the 1955 Mille Miglia (start time 7:22 a.m.). The factory archive lists it as a limited series of 150, with more power, more speed and quicker acceleration than the standard SLR.

How rare is it?

Six separate kinds of rarity – never combined into one number.

Each kind of rarity is rated separately and never combined.

Production

Every figure says what it counts.

Independent counts (e.g. engine and colour) are never combined into a calculated figure. Surviving examples are never presented as original production.

History

The archive gives the production period of the 722 Edition as August 2006 to June 2008 and list prices of EUR 464,000 (July 2006) and EUR 476,000 (January 2007). Its 5439 cc supercharged M 155 V8 is rated at 478 kW / 650 hp and 820 Nm, against 460 kW / 626 hp and 780 Nm for the standard SLR, and the archive quotes 337 km/h and 3.6 s to 100 km/h.

RM Sotheby's says more than 300 components were modified: ride height was lowered by 10 mm, new 19-inch wheels were designed to fit larger carbon-ceramic brakes, and a carbon-fibre front splitter increased front downforce. RM adds that only about 25 of the 150 cars are believed to have gone to North America. The auction houses quote 641 bhp or 650 bhp for the same engine; the archive figure is 650 hp.

Identification guide

How to tell an original from a replica or later conversion.

Auction catalogues list the following 722 Edition features: red "722" badging, black-tinted headlamps and tail lights, a revised front air dam with carbon-fibre splitter, a rear diffuser, 19-inch wheels with 390 mm carbon-ceramic brakes, a lowered ride height, and a carbon-fibre, black leather and Alcantara interior. Artcurial adds red-background dials with a "722 Edition" badge. Per the archive the car carries the same type number as the standard SLR coupé (199.376) and the same design name, C 199 E 55 ML, so the 722 features rather than the VIN are the marker. Chassis numbers in the cached lots begin WDD1993761M or, for the US car, WDDAJ76F27M.
