The secret? A new steering
A new steering system was developed by engineer Franck Schweickhardt and his team. It's been improved to feature a variable rack ratio, which adjusts in line with the steering angle, increasing sharply as soon as it reaches five degrees. All of which means that, compared to a steering system with a constant ratio, the driver does not have to turn the steering wheel as much when cornering. When dealing with anything beyond 90-degree corners, the car amazes with its ability to grab a hold of the road despite its commanding size. You'll go from lock to lock only when parking the SL or making a U-turn.

Prestige or pleasure
Both apply to the new 2009 Mercedes-Benz SL550 and SL600. While pricing has yet to be announced, expect it to be under the 2008 models' ($135,000 and $181,000, respectively). These cars will easily rival every other premium grand tourer on the market. They bring lots of comfort and prestige to the table but also true driving pleasure.
