From 1961 until 1971, Mercedes-Benz built the two-door cabriolet known as the W111 convertible. Its soft-top roof folded into a compartment behind the back seat and was based on the W111 saloon. The Mercedes-Benz W111 220SEb convertible featured a 2.2L inline six engine with 120 horsepower DIN/134 hp SAE gross (88/100 kW) and 127 lb-ft of torque available as an option (172 Nm). The 2.5L inline six engine in a later Mercedes-Benz W111 250SE convertible produced 150 PS (148 bhp – 110 kW) and 162 lb-ft of torque (220 Nm).
The 3.5L V8 engine in the Mercedes-Benz W111 280SE 3.5 convertible produced 200 PS (197 bhp – 147 kW) and 211 lb-ft of torque (286 Nm). The W111 convertible is now regarded as a classic vehicle and has received praise for its sophisticated styling, plush interior, and comfortable ride.
