For the first time Karl Benz publicly drove the car on July 3, 1886, in Mannheim at a top speed of 16 km/h (10 mph). [10] Benz later made more models of the Motorwagen: model number 2 had 1.1 kW (1.5 hp) engine, and model number 3 had 1.5 kW (2 hp) engine, allowing the vehicle to reach a maximum speed of approximately 16 km/h (10 mph).

Two common definitions used today are the imperial horsepower as in "hp" or "bhp" which is about 745.7 watts, and the metric horsepower as in "cv" or "PS" which is approximately 735.5 watts. The electric horsepower "hpE" is exactly 746 watts, while the boiler horsepower is 9809.5 or 9811 watts, depending on the exact year.
However, cars with front-wheel drive were made several years earlier in road cars produced by Alvis and Cord as well as in racing cars by Miller (and may have appeared as early as 1897). In the same vein, the independent suspension was initially developed by Amédée Bollée in 1873, but not put in production until the low-volume Mercedes-Benz ...

From 1894 to 1902, Benz produced over 1,200 of what some consider the first mass-produced car, the Velocipede, later known as the Benz Velo. [20] The early Velo had a 1L 1.5-metric-horsepower (1.5 hp; 1.1 kW) engine, and later a 3-metric-horsepower (3 hp; 2 kW) engine. giving a top speed of 19 km/h (12 mph).
All 1959 Pontiacs were equipped with a 389 cu in (6.4 L) V8 engine with horsepower ratings from 215 hp (160 kW; 218 PS) to a 345 hp (257 kW; 350 PS) "Tri-power" carbureted version. All automatics were four-speed Super-Hydra-Matics or, as the Hydramatic Division that designed and built them called them, "Controlled coupling HydraMatic".
