IL Track Tested: 2009 Mercedes S550 vs. 2000 BMW 750Li

dear god, look at the miracle ABC (active body control) does on that S class. when it goes through the skid pad, it looks completely flat.

Vehicle: 2009 BMW 750Li
Odometer: 1,968
Date: 04/07/09
Driver: Chris Walton
Price: $89,825
Specifications:
Drive Type: rear wheel drive
Transmission Type: 6-speed automatic
Engine Type: V8
Displacement (cc / cu-in): 4,395cc (268 cu-in)
Redline (rpm): 6,500
Horsepower (hp @ rpm): 400 @ 5,500
Torque (lb-ft @ rpm): 450 @ 1,800
Brake Type (front): Ventilated disc
Brake Type (rear): Ventilated disc
Steering System: Speed-proportional power steering
Suspension Type (front): Double wishbone
Suspension Type (rear): Multilink
Tire Size (front): 245/45R19
Tire Size (rear): 275/40R19
Tire Brand: Goodyear
Tire Model: Excellence
Tire Type: All-season
Wheel Size: 19-by-8.5 inches front -- 19-by-9.5 inches rear
Wheel Material (front/rear): Alloy
As tested Curb Weight (lb): 4,607
Acceleration Comments: I tried so many combinations (Sport, Sport w/Dynamic Traction, Sport w/DSC off, etc.) that I can't say with certainty which one was quickest. I think Sport +, DSC off, manual shift (but still auto upshift) was the winner. Zero wheelspin was definitely the best and geez is this thing a rocket. Shift were fast, bordering on harsh, and the power felt limitless.
Braking Comments: At a loss to explain diverse stopping distances (perhaps a hop in the pavement), but the brakes always felt strong and fade-free. Huge initial bite, then a superfast ABS cycle with zero drama. More dive than expected, even in the Sport chassis setting.
Handling Comments: Benign understeer at the limit with DSC off that was diminished greatly with DSC on -- which proved to be the quicker way around the skid pad. Steering gets much heavier as speed increases. (Slalom) Amazingly "buttery" steering feel, good turn-in, but there's no doubt this is a long-wheelbase car. Good balance, but even in sport chassis mode there's more roll than I expected, plus understeer at the limit. Also noticed that the seatbelts snug up when you start tossing this car around.

Tire Type: Performance
Wheel Size: 19-by-8.5 inches front -- 19-by-9.5 inches rear
Wheel Material (front/rear): Alloy
As tested Curb Weight (lb): 4,630
Acceleration Comments: Responds well to brake torque, but not wheelspin. Smooth linear power delivery with aggressive exhaust note. Shifts are buttery smooth, but not very quick.
Braking Comments: Crazy powerful brakes that don't fade a bit. Very little dive, but pedal is always a little soft. Belt cinches tightly when ABS engages.
Handling Comments: (Skid pad) In both skid pad and slalom tests, I couldn't detect any difference between ESP on and ESP off. Also the Active Body Control (ABC) is very strange, but works amazing well -- keeping all four tires firmly planted. Delivers zero body roll, which makes it easy to keep on line with only minor corrections. (Slalom) Through the slalom, ABC leans the car into the turn like a skier! Very strange. In the end, ABC and ESP made every run easily repeatable. Same speed with ESP on or off.

Nice review, these are two heavy vehicles and regardless of strut braces and beefed up struts, their will always be sacrifice in slalom. Should not effect sales though (lol).

Thanks for posting!I like the look of both car but in my opinion, their looks are not greater than LS460 is. Also, Do you guy notice that the rear left light on the BMW 750 Li in this review already went out (check the review clip at 1:34). This is something i found interesting

I dont think cars like this should be weighted to heavily on their track prowess. Its all about seat comfort, low decibel cabins at 150 mph, heated back massage, and night vision.

Active Roll Stabilization is an "active" suspension control system design to reduce body roll in cornering, resulting in improved handling. Whenever entering a corner, "lateral acceleration" is generated. Sensors read the level of body roll and communicate with the ECU or central "brain" which then processes this signal and coordinates various systems to respond. As a result, ARS actively generates resistance to body roll by twisting the front and rear anti-roll bars appropriate to the situation.
