Safety will again take center stage as the 2007 S-Class will be the first Mercedes to offer its second-generation Presafe system featuring BrakeAssist Plus. The system uses radar to sense vehicles ahead and will sound an alarm if cars get too close. When the system senses an impending impact, BrakeAssist Plus can calculate the brakeforce needed to stop the car safely and apply it as soon as the driver presses the brake pedal.
Like the current lineup, the 2007 Mercedes S-Class is expected to be offered with two V8 engine options, both slightly larger and more powerful than the current 4.3-liter and 5.0-liter power plants.
Mercedes introduced high performance variable-valve-timing quad-cam 4-valve V8 in the 1990 SL500 and continued through 1998. Chrysler era cost reductions replaced these engines with lower performance 3-valve V8s in the 1999 - 2006 SL500s, including the V8 offerings in every other 2006 model. The 3-valve engines offer the same EPA fuel economy with less power and less torque compared to the 1990 - 1998 4-valve engines. Of course marketers promoted this downgrade as some sort of benefit. Even the six-cylinder models stepped back to simpler technology and lower performance.
