2018 Porsche 718 Cayman vs. 2018 Mercedes-Benz SLC 300

For decades, both Porsche and Mercedes have remained at the top of the auto world, producing outstanding vehicles which provide drivers with a one of a kind experience. They continue this tradition in 2018 with the release of the Porsche 718 Cayman and SLC 300 respectively, both of which are so highly esteemed that it will be difficult for prospective buyers to choose, but below is a comprehensive analysis.

Design & Style

Both these vehicles are immaculate in terms of appearance. Anyone who is seen driving in either will instantly convey sophistication, style, and extraordinary wealth. The Mercedes SLC 300 is slightly more angular than the Porsche, but compared to past Mercedes models is curvier.

Technology & Safety

The Mercedes SLC 300 has more airbags than the Porsche 718, at 9 versus only 7. The Porsche however has slightly better infotainment, with a higher screen size than you’ll get in the Benz. Both feature a keyless start and the Mercedes comes equipped with a filter for pollen and dust, along with a compass that is integrated, memorized power seats, and a bunch of other amenities. In terms of fuel economy, the Mercedes beats the Porsche, at 25 mpg versus only 21 mpg.


The Porsche offers vastly more horsepower than the Mercedes at 300 hp versus a paltry 241 hp for the SLC 300. While it takes the Porsche 4.9 seconds to go from zero to sixty miles per hour, with the Mercedes you’ll have to wait 5.8 seconds. The Porsche has slightly more torque, at 280 Ib versus 273 Ib for the SLC 300. Both vehicles have the same drivetrain, but the Porsche uses a six-speed automatic transmission while the Mercedes uses a nine-speed automatic. Although the Porsche has a decisive edge in overall performance, the Mercedes does surpass it when it comes to the number of gears it utilizes. The nine-speed automatic transmission means that the Benz will have gear changes which are much smoother.

The Bottom Line

While these two cars are similar in many respects, the Porsche is slightly more expensive, at $55,000 versus just over $48,000 for the Porsche. But in exchange for paying the extra cash, you’re getting a vehicle that performs substantially better. When designing the SLC 300 it is obvious that Mercedes prioritized luxury amenities over power and acceleration, which is understandable to a certain degree. But for those who are looking for maximum performance, and don’t mind paying a little extra for it, the Porsche 718 Cayman wins this contest hands down.
