2012 Mercedes-Benz SLK55 AMG
How does it do it? With a familiar AMG recipe, adding more power, better handling, a dash of race-inspired design, and, of course, AMG exclusivity. Yet the SLK 55 remains the most "lifestyle" oriented vehicle in the range by AMG chief Ola Kallenius' own statement. How do these two personalities co-exist in one smallish roadster? Quite well, actually.
Disclaimer: Mercedes-AMG flew us out to San Francisco for a drive down the coast to Monterey where we drove yet another AMG product at Laguna Seca (look for that review shortly). Along the way, the Germans did their best to throw our blood sugar, cholesterol, and liver enzymes completely out of whack. Fortunately, they failed.
As we light off through downtown San Francisco toward our destination in Monterey, via fantastic winding roads that slice through verdant Redwood-lined vistas, it's immediately apparent that this AMG car is a bit different from the rest. Among the rest of the AMG range, even the CLS 63 AMG, there's a tendency for the softest "comfort" suspension setting to be a bit harsh for daily driving in cratered urban streets. Not so with the SLK 55.
There's still a sport-oriented firmness to the ride, but the dampers have been tuned to demand less from the driver and more from the car--a much better balance for top-down cruising. And that's how we set out despite the slightly damp November chill to the Bay Area air.
With the windows up and the climate control system set, the cabin is neither turbulent nor uncomfortably cold. A mesh divider between the seats helps to settle the wind. We cruise in comfort with the top down for over an hour, enjoying the sound of the 5.5-liter naturally-aspirated V-8 and its 415 horses reverberating from first the buildings, then later then trees, as we (rapidly) work our way to our destination.

In more restrained driving, the SLK 55 AMG shines in a surprising area: fuel efficiency. With cylinder deactivation tech that shuts down one bank of the V-8's cylinders, the SLK 55 can run on four cylinders in cruising mode from 800 to 3,600 rpm, yet transition back to eight-cylinder mode instantly and almost transparently, with only a brief burble and the tiniest vibration through the accelerator to indicate the switch. When flowing with traffic at 50-70 mph on mixed two-lane and freeway, we saw the fuel economy frequently tip up past 30 mpg. And with auto stop-start, we didn't see those figures fall far once we entered town and started the stoplight stutter-step.
Once you get back out on the fun roads, however, you'll find steering is precise, if muted in its feel and feedback, quick to turn and neither too light nor too heavy for quick changes in direction. Body roll is minimal, when in sport mode, and the transmission, Mercedes' 7-speed Speedshift clutched automatic, is a ready partner in either automatic or manual modes. The large paddles are easy to grab even when a shift is necessary while there's still some steering angle dialed in.

With the sun fully out and beginning to roast our tender, chained-to-a-desk skin, we decided it was time to put the top up. It's a simple and quick affair, just a button press away--though you do have to be at a full stop for it to operate, or at least we did. Once the top is up, the SLK is much more coupe-like; that is to say, quieter, more closed-in feeling.
Fortunately, there's the Magic Sky Control roof, which can be adjusted from nearly opaque to fully transparent, spanning almost the entirety of the main roof panel. Switch it to clear and the cabin opens back up, exposing the outdoors to your eyes, but preserving the rest of the coupe-like peace. It's a great combo.
Except that the improved serenity of the hardtop cabin reveals another issue: a squeaking sound from somewhere just behind me. Upon further investigation, it's the back of the seat rubbing against the bulkhead as the chassis flexes slightly. My passenger and I notice this because we're both over six feet in height--meaning our seats are back as far as they'll go. Those that sit a bit farther forward might not have the same issue.
