The Mercedes-Benz W125 was a Grand Prix racing car produced by German auto manufacturer Mercedes-Benz to race during the 1937 Grand Prix season. Designed by head designer Rudolf Uhlenhaut, the car was used by Rudolf Caracciola to win the 1937 European Championship and W125 drivers also finished in the second, third and fourth positions in the championship.

The W125 was powered by a supercharged double overhead camshaft 5,663 cc (345.6 cu in) capacity 94 mm × 102 mm (3.70 in × 4.02 in) inline 8 which produced 595 horse power (444 kW) in race trim. Its highest test bed power measured was 637 BHP (646 PS) at 5,800 rpm, with 245 BHP (248 PS) developed at a mere 2,000 rpm. In 1938, the engine capacity of supercharged Grand Prix cars was limited to 3000cc, and the W125 was replaced by the Mercedes-Benz W154.

The W125 was considered the most powerful road racing car ever for three decades until large capacity American-built V8 engines in CanAm sportcars reached similar power in the late 1960s. In Grand Prix racing itself, the figure was not exceeded until the early 1980s (when Grand Prix racing had become known as Formula One), with the appearance of turbo-charged engines.

The W125 reached race speeds of well over 300 km/h (190 mph) in 1937, especially on the AVUS in Berlin, equipped with a streamlined body.

In land speed record runs, a Mercedes-Benz W125 Rekordwagen was clocked at 432.7 km/h (268.9 mph) over a mile and a kilometre. This car was fitted with a DAB V12 engine (82 x 88 mm) of 5,576.75 cc (5.6L, 340.31 CID) with a power of 726 hp (736 PS) at 5,800 rpm. The weight of this engine caused the car to weigh over the 750 kg maximum limit, so it never appeared in Grand Prix.
