Mercedes-Benz and Porsche are two of the top luxury automakers in the world, consistently outselling and outperforming the competition at a high level. It only seems right to put them in a side-by-side comparison in this 2020 Mercedes-Benz SL Roadster vs 2020 Porsche 911 Carrera matchup. They are both excellent choices for open road adventures, but which one is the better choice? We’ll let you be the judge!

Both models are sure to turn heads in the streets, but there’s one notable difference where the SL Roadster shines ahead of the 911 Carrera: it has a standard nine-speed automatic transmission that allows for more seamless gear changes, better top-end fuel efficiency, and quicker acceleration than the seven-speed manual that comes standard in the 911 Carrera.
