A legend since its introduction in 1957, Mercedes-Benz's SL roadster has long been considered the standard by which other luxury convertibles are judged. Dynamic designs, advanced engine technology and exquisitely detailed interiors have made the SL
the convertible of choice for high-rolling business executives and Hollywood stars alike.
The redesigned 2003 model begins the fifth generation of this automotive icon, and if our short-lived stint behind the wheel is any indication, the SL mystique will live on for many years to come.
Although our final scoring calculations only show a narrow victory over the second-place Lexus, the SL was the clear winner in that most empirical of categories our hearts. When posed the question of which car they would want in their own garage, six of our eight editors picked the Mercedes with little hesitation (the other two held out for Porsche's 911).
Whether it was the growl of the torque-rich V8, the ultra-stiff and well-balanced chassis, the elegantly appointed interior, or the fully automatic hardtop, the SL rarely failed to overwhelm us with its technological and aesthetic supremacy. Sure, there are still elements of this Teutonic wonder that we could do without, but with all nit-picking aside, there's little doubt that this latest iteration of the Mercedes' flagship roadster is without equal. In the succinct words of our editor in chief, the SL500 is "simply the best luxury drop-top you can buy."
Slide yourself in the low stance and high door sills make for a bit of a tight squeeze and the SL's cabin impresses with a simple yet distinctive design. Nearly every surface is covered in fine leather, with straight stitching running along every crease and corner. Deep recesses render the elegant gauges readable in even the most sun-drenched conditions, and a low cowl affords an excellent view of the road ahead.
Despite the heavy dose of electronic gadgetry on board, the dashboard is free from excessive clutter. Even Mercedes' notoriously complex climate control system has been simplified to include just two dials and a handful of control buttons. We found its operation straightforward enough, although the dials themselves were loosely attached, one of the car's few lapses of perfection. The COMAND audio/navigation system continues to disappoint, with its frustrating interface, outdated CD-ROM technology and lack of an in-dash CD changer.
Driver and passenger comfort is attended to with 12-way-adjustable seats and standard bi-level heaters. Our particular test car also had the Comfort package, which includes active ventilation and pulsating lumbar support for the seats. There's more room to stretch out than in previous SLs, allowing even our tallest editors to find a comfortable driving position. In typical German fashion, the seats are well contoured and extremely supportive. But if you prefer couch-like accommodations, you might find the SL's seats a bit on the stiff side.
The in-seat ventilation is nice, but if you really need to cool off a little, there's no better respite than the fully automatic hardtop that folds itself away in just 21 seconds. Wind buffeting at speed is barely noticeable, and with the manually controlled windscreen in place, the SL is virtually gust-free at any speed. Even more impressive is the fact that even with the top down, there's still more trunk space than in previous models. There's even a button that raises the folded hardtop within the trunk for easier loading.
Whether you like the interior or not, any misgivings will quickly melt away at the first turn of the key, or press of the button, depending on how you go about it. One of the SL's unique options is a keyless ignition system that allows you to access and start the vehicle with nothing more than a credit card-sized transponder. Those who used it found it appealing, but we don't consider it much of an improvement over traditional keyless-entry systems.
The 5.0-liter V8 that powers the SL is largely a carryover from last year's model, although modifications to the exhaust system make it sound as if it might be all new. The refined note of the previous version has been uncorked a bit to deliver a more satisfying howl. Some might consider the sound a little too pervasive for a luxury car of this type. We couldn't get enough of it.
With 302 horsepower, the SL competes favorably in this class, but overwhelming power is not its forte. The wide torque band and smooth delivery make just about any type of drive a pleasant one, but occasionally we found ourselves wishing for just a bit more from under the hood. Should you feel the same way, wait a few months as AMG, Mercedes' in-house tuning arm, will release its version of the SL, complete with a supercharged V8 and nearly 500 horsepower.
We had no such reservations about the standard five-speed automatic transmission. Shifts were seamless and precisely timed. The Touchshift manual mode works well, but having to take our hands off the wheel to manipulate the lever is a step we could do without. Steering wheel-mounted buttons like those in the Porsche would be a welcome upgrade.
Previous versions of the SL were always competent, but rarely sporty. The '03 edition effectively ups the ante without sacrificing comfort or everyday drivability. The steering remains light under normal conditions and firms up nicely at speed for more road feel. Unlike the 911, which can be harsh on occasion, the SL rarely transmits any upsetting jolts to the cabin. The standard driver-selectable Active Body Control turns this cruiser into an incredibly capable partner when the road gets tight. Body roll is almost nil, and even with the top down, chassis flex is barely noticeable.
Mercedes calls its stability control system ESP (Electronic Stability Program). After pushing the SL through a 600-foot slalom course at high speed, we couldn't help but consider the name most appropriate. Unlike some systems that intervene at the slightest hint of slide, the SL has a near-perfect sense of what the driver is intending, intervening only at the last second to restore control.
An electrohydraulic braking system, the first of its kind in a production car, is another of the SL's newest technological features. This system effectively replaces the traditional mechanical connection between the brake pedal and the brakes with electronic circuitry. The goal is more immediate application in panic situations along with less overall complexity. The system proved its worth at the test track, as the SL came to a stop from 60 miles per hour in just 109 feet one of the shortest distances we've ever recorded. As effective as the new system is in emergency situations, it's still not completely refined, as more than one editor complained of poor brake feel in day-to-day driving.
So it's not perfect, but no car ever will be. It is, however, about as close to perfect as you can get when it comes to luxury roadsters. Beautiful to look at, comfortable and fun to ride in, intoxicating to listen to the SL blends all the things that make driving pleasurable into one expertly crafted package. Now if Mercedes could just work on lowering that price a little, we would
really be sold.
SECOND OPINIONSRoad Test Editor John DiPietro says:This car has the goods to satisfy on nearly all fronts. Performance? Got that covered. I was skeptical before I took the wheel, thinking that all those electronic acronyms would make for a drive that would feel artificial. Such was not the case. Apart from the "by-wire" brakes that felt a bit touchy at first, the new SL offered a sense of the road that the older models lacked. The net effect was that the car felt smaller than its considerable heft. Comfortable? Yep, thanks to a compliant ride and great seats. Style? Dandy except for the cut lines for the trunk that disrupt the profile (a necessary evil to allow the top to drop into the trunk). Of course, I would've liked more power (geez, isn't 302 horsepower enough?). Oh, that's right, the near-500-horse SL55 is just over the horizon. Is this the golden age of the automobile or what?
Senior Editor Christian Wardlaw says:Money sometimes is not an object. If you find yourself thinking this way when considering the four convertibles in this test, then the Mercedes-Benz SL500 is the right car for you. It is a gorgeous piece of work, from the tight yet expressive styling to the engineering marvel that is its folding hardtop to the comfortable and functional interior to the refined and powerful drivetrain, the SL500 does it all...but for a price.
Is it a touring car or a sports car? The answer is that it is both, equally capable idling in rush hour traffic as it is blasting along a favorite coastal road at supra-legal speeds.
Unflappable is the word that describes the SL500 best. Officially, there is no reason to accept a Porsche 911's rearward weight bias, darty steering and buckboard ride to own a vehicle that can perform. The Mercedes is every bit as capable at the limit and doesn't punish its driver during the daily grind.
Two complaints can be made with regard to the SL, and both are associated with the interior. First, and this is a gripe I've made with all Mercedes-Benz products since the launch of the current-generation S-Class, many of the interior plastics are of sub-par quality for a vehicle that can cost nearly $100,000. For example, the rearview mirror feels loose and creaks when adjusted; I've felt more substantial mirrors on many cars that cost less that 20 grand. Second, the fussy COMAND system makes channel surfing and operating the stereo a chore, and keeps Mercedes from offering a proper six-disc in-dash CD changer.
Otherwise, the car is a pleasure to drive. It's easy to load and unload luggage from the trunk even when the top is folded, the seats offer myriad adjustments for optimal comfort, the sound system sounds terrific with the top up or down, and this is a true four-season drop-top.
Money is not an object? This is your next ride.
Road Test Editor Erin Riches says:If money isn't a concern (our test car was closing in on six digits), the SL500 is close to perfect as a touring roadster. The V8 effortlessly reaches cruising speed, and when left in regular D mode, the automanual transmission shifts quickly. As you're enjoying coastal vistas at a leisurely pace, the suspension delivers the requisite smooth ride; later, when you're ready for more serious driving, the SL and its ABC are ready for flat, confident cornering. Inside, the cabin has a traditional Mercedes look to it, which is to say, handsome but cluttered I counted seven unused "dummy" buttons (presumably for options the test car didn't have) on the center console alone. For the most part, designers used high-quality soft-touch materials, though I didn't like the hard plastic cover on the gauge bezel or the vinyl sunvisors and headliner. In addition, build quality wasn't as good as I thought it should have been the trunklid, hood and driver-side mirror were misaligned, and the sunvisors had rough edges on them. Am I coming down hard on the SL? Sure I am, but for this kind of money, everything should be flawless. If you buy this roadster, I doubt you'll be disappointed, though for myself, fun trumps comfort and I'd take the 911 instead.
