Notes

    Mercedes substantially revised the S-Class for 2003, changing every model in some form or another. The sedans were facelifted with a new, bolder look that incorporated larger clear-lens headlights, and all models except the S55 AMG gained new tires. The interior was also refreshed, and the cassette deck was removed from the stereo system. To improve sales in the Snowbelt states, where rear-drive cars were still considered somewhat suspect, Mercedes unveiled all-wheel-drive variants of the S-Class: the S430 and S500 4Matic models. The AWD system used an open center differential with a 40/60 front/rear torque split. The S500 Guard edition was purged from the lineup. The real change for 2003, though, was the unexpected power boost for the top-of-the-line models. The tuners at AMG fitted a supercharger to the handbuilt 5.4L eight-cylinder, increasing power by 138 bhp. And, saving the best for last, Mercedes dropped the Maybach engine, with slightly reduced turbo pressure, into the S600 to produce one of the most powerful sedans ever produced. Like the S55, it produced 493 horsepower, but at lower revs, and it belted out nearly 600 pound-feet of torque. More than a second was cut from its 0-60 time, but in exchange, fuel economy got even worse. A reinforced 5-speed automatic gearbox kept the two juggernaughts from shredding their drivetrains. A new option for 2003 was the PreSafe system, which used sensors to detect an impending collision (based on yaw momentum and other factors) to trigger automatic safety responses. The seatbelts were cinched tightly, the sunroof was closed, and the seats would reconfigure themselves to the optimal angles for airbag deployment. It was a remarkable system, and the first of its kind, although not for long. And, finally, Mercedes made a heated steering wheel available on the S-Class, one of the few luxury touches that its flagship sedan had lacked.
