The Mercedes-Benz SLK is now in its third generation, and by the numbers, gen two and gen three are much more closely related. The 2012 model rides on a wheelbase of 95.7 inches, and measures 162.8 inches in all, which makes it nearly identical in size to the prior version.
It has grown a bit broader, but it's hard to gauge in shoulder room; it just doesn't seem meaningfully larger. Most passengers will fit fine, but our taller editors--basically, all of them--think the SLK could use an inch or two more leg room, and more seat travel. The sport seats themselves fit perfectly snugly, but you'll sit close to the dash. We've also noticed the passenger footwell doesn't have as much space, which can make very long drives a little tiring. Very tall passengers will have some geometry to figure out--how far back can I move the seat before I need to adjust the backrest more vertically than I would like?
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. 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.
