The SLR 722 takes only 3.6 seconds to reach the big six-oh, or two-tenths quicker than the standard SLR. Stiffer suspension, new 19-inch wheels, and brake rotors twenty millimeters larger are also part of the package. Top speed rises by one mile per hour to 209; a modified front spoiler and rear diffuser help keep things on the ground.
Yes, that's right, the SLR hasn't exactly been selling well. What's that, you say? You mean, if you had $452,750, you wouldn't go buy an automatic-transmission-equipped Mercedes---no matter how cool and pimpy and McLaren-built it was---either? Us too.
