2018 Porsche 911 vs. 2018 Mercedes Benz SL Class

The 2018 Jaguar XF may be a popular choice among car buyers, but the 2018 Porsche 911 steals the show with high-performance engine options. If you are looking to pick one, this comparison will give you a good idea as to why Porsche is a preferred choice.

Design & Style

The 2018 Mercedes Benz SL Class is a 2-seater vehicle with ample legroom and headroom on offer, making it easy for the passengers to take a ride. The cabin does not look as modern as other rivals, but it is quite upscale with top-quality materials.

For the Porsche 911 model, it is a 4-seater, while the GT3 version seats two. It’s better to leave the rear seats folded down to accommodate extra cargo space. The front seats are quite supportive and roomy, with plenty of head and leg space. The styling looks amazing with high-quality materials throughout the cabin with leather upholstery. Given the attention to detail Porsche pays, even small trim pieces have a great appearance.

Technology & Safety

Technology and safety are important factors to consider when looking to purchase a car. Some of the standard features in the SL Class includes COMAND infotainment system with features like satellite radio, two USB ports, Bluetooth, Android Auto, Apple CarPlay and navigation system. The infotainment system is not quite user-friendly as some rivals, as the screen is small and the interface is hard to master. Some of the active safety features include Mercedes Pre-Safe, driver drowsiness monitoring and a rearview camera.

On the other hand, Porsche 911 has standard features including infotainment system, satellite radio, Apple CarPlay, Wi-Fi hotspot and Bluetooth. The infotainment system is quite intuitive and you will find it easy to navigate through the menus. For safety, we have features like parking assist and a rearview camera.


Each Mercedes Benz SL trim has its own engine, ranging from the V6 362-HP powertrain to the 621-HP V12 powertrain. The base engine has enough power from a practical standpoint. This is where Porsche 911 is a winner with a higher number of performance variants. For the base 911, it can crank power in the range of 380-450 HP, and there is sufficient output for driving in any condition. Go for 911 Turbo and 911 GT3, if you are considering higher trims.

The Bottom Line

There’s tough competition for both the models, given the set of excellent attributes they have got to offer. But Porsche 911 has an edge with plenty of engine options and smooth handling, along with top-notch technology, design and performance.
