The old S-Class interior was luxurious, functional, comfortable, yet cold and forbidding, like the home of a rich widowed aunt where children are firmly reminded to remain on their best behavior. The 2000 S500's cabin is warmer and more inviting. There's an almost Mediterranean influence in the way Mercedes designers have melded wood, metal and leather. You feel like you could stretch your feet out and relax on the sofa.
The new S500 has a cockpit-like feel and a formidable array of electronic features.
The most notable is the Distronic Active Cruise Control system. Set your desired speed, and it uses a radar system to scan the road ahead. If you come upon slower traffic, or someone unexpectedly pulls into your lane, Distronic will back off the throttle, downshift, even apply up to 20 percent of the car's braking force in order to maintain a safe distance. You can set a following distance of between 1 to 2 seconds behind the car ahead. The idea of handing control of your car over to a computer might seem a little bit disconcerting, but we found Distronic a near-miracle on wheels, requiring us to touch the pedals only once while driving a crowded, 30-mile stretch of Autobahn outside Zurich. The setting you choose for Distronic can be displayed on a neat little video display mounted just below the car's speedometer.
The read-out is also used for other features, including navigation. Like other mapping systems now on the market, the S-Class will plot the best route to your destination using a small display below the speedometer, a larger monitor in the center of the instrument panel or it will speak to you in a pleasant voice.
Even the seats in the S500 have gone high-tech. Heated seats are standard fare in many cars these days, but S-Class seats are fitted with 10 small fans that blow cool air through the upholstery, onto the driver's body. An optional massaging seat is equipped with air bladders in the lower back and shoulder areas that automatically inflate and deflate as you're driving to reduce stress on long journeys.
Another system, called Parktronic, uses sonar to help you park in tight places without playing bumper cars. When you're down to the last few inches from an obstacle ahead or behind, it flashes a warning and sounds an alert. There's also a new key card ignition system coming that will replace the traditional car key with a credit card-sized transmitter you can stick in your wallet.
Bigger-is-better" seems to be the automotive mantra in the age of the full-size sport-utility vehicle. The old S-Class proved the fallacy of that logic. The new S500 is just big enough, and the result is a modestly downsized sedan that's markedly more nimble and aggressive, as we discovered driving a looping route through the foothills of the Swiss Alps.
The 2000 S500 is powered by a 5.0-liter V8 pumping out 302 horsepower. That's slightly less muscle than the old car, but you're not likely to notice. Stomp on the accelerator, and you feel an extra kick, the most immediate payoff of trimming the car's weight. And it's more than just throttle feel. Steering is more precise, with far more road feel than the last-generation S-Class, a car that seemed numb by comparison. The suspension is firmer, but certainly not harsh. Setting the transmission into S, or Sports, mode, yielded crisp, aggressive shifts, and there's a new Tiptronic-style mode. In manual mode, you tip the shift lever left or right to downshift or upshift, or simply leave it in "D" for fully automatic operation.
The old S-Class was always a chore to drive in Europe, especially on the hills and lake country roads we roamed outside Zurich. The new car is still quite imposing, and more than a few times we found oncoming traffic meekly yielding to us as we raced down a narrow lane. Yet this car feels surprisingly agile for its size. Give some credit to the AIRmatic suspension, which replaces the usual steel coil springs in the suspension with air-filled rubber bellows. At speeds over 68 mph, it lowers the car a half-inch. There's also an Adaptive Damping System, or ADS, which automatically adjusts shock-absorber settings to match the moment's driving conditions.
