The 2015 Mercedes-Benz S65 AMG made its debut at the 2013 LA Auto Show on Nov. 20.

The 2015 S65 AMG comes with a new seven-speed “AMG Speedshift Plus” automatic gearbox—an upgrade from the 2014 model’s five-speed transmission.  It will do 0-60 in 4.2 seconds and top out at 155 mph.

The inside is filled with luxury features like the diamond-quilted Nappa leather and IWC Schaffhausen clock built into the dashboard. Other features include a 24-speaker sound system, massage function, sunroof, and surround-view camera.

The 2015 S65 AMG will not go on sale until the second quarter of 2014. Pricing details are expected to be released closer to the launch date.
