The Mercedes-Benz SLK was hardly in need of improvement in the styling department so when it came time for a midlife facelift developers didn’t muck around too much with the look of the car. Instead they chose to modify it where it matters the most – under the bonnet. For the 2009 model year, engineers managed to add more power and torque while decreasing emissions for the entire engine lineup, including four, six and eight cylinder powerplants. In addition to the new performance upgrades, Mercedes has also launched a new accessory line for the SLK, which you can see in our full gallery after the jump.
