The greatest German engines ever made

The 200km/h (124mph) target speed was beaten during a successful Land Speed Record attempt in 1909. A later 142mph run did not take place under LSR regulations, but driver Bob Burman (1884-1916) had unofficially reached the highest speed achieved to date by any vehicle, including aeroplanes.

BMW M20

BMW is renowned for its smooth-running straight-six engines. A classic example of the type is the M20, introduced to the 3 Series and 5 Series ranges in 1977 as a 2.0-litre. It subsequently appeared with capacities of up to 2.7 litres before being discontinued in the early 1990s.The M20 was mostly fitted to saloon cars, but also powered the radical BMW M1 roadster in 2.5-litre form. In 2.0-litre form, it was noticeably smoother than four-cylinder rivals, as this famous advert from the ‘80s emphasises.

BMW S14

The S14 was a high-revving four-cylinder engine used in the first-generation BMW M3. For road cars, it appeared first in 2.3-litre form and was later expanded to 2.5 litres. For motorsport, it was often reduced to 2.0 litres to meet championship regulations.

The scream of a tuned S14 made the M3 a very dramatic rally car, but it was even more successful in circuit racing, winning the Australian, British, German, Italian, European and World Touring Car Championships.

BMW N74

The N74 is a twin-turbo V12 which has been available in various capacities from 6.0 to 6.75 litres. Power outputs have ranged from nearly 540bhp to over 620bhp, but the engine is not intended for use in sporting cars.

The only BMWs fitted with it have been upscale members of the 7 Series family like the M760Li xDrive pictured. Since 2010, it has also been used in models produced by Rolls-Royce, which BMW currently owns.

Bugatti W16

Although Bugatti is a French brand, it is owned by Volkswagen, and uses a great deal of German technology. This includes a formidable quad-turbo 8.0-litre W16 engine, whose unique layout was created (more or less) by mounting two narrow-angle 4.0-litre V8s on a shared crankcase.

The engine had already appeared in the Audi Rosemeyer and Bentley Hunaudieres concept cars before reaching production in the 2005 Bugatti Veyron (pictured). In most Veyrons, the W16 produced 987bhp, but its output was raised to 1479bhp for the Bugatti Chiron, which replaced the Veyron in 2016.

Daimler DB603

The DB603 was one of the most remarkable engines developed in Germany or anywhere else for use in a car. The car in question was the Mercedes T80, which was designed for an attempt on the Land Speed Record. The 44.5-litre V12 produced around 3000bhp, which seemed like enough when the project began in the mid 1930s.

The Second World War diverted everyone's attention from record breaking. By the time Mercedes was in a position to think about it again, the record had been raised to 394mph. Since that was 21mph above the target speed for the T80, the project was abandoned.

DKW two-stroke

By acquiring a patent for a system called loop scavenging, using it well and setting the lawyers on anyone who came close to it, DKW became the world's leading manufacturer of two-stroke cars and motorcycles. It was so successful that it could afford to buy Audi in 1928.

DKW finally developed the four-stroke F103 in the 1960s. Its then owner, Volkswagen, resurrected the by now long-dormant Audi name rather then persevere with one associated with noisy, smelly engines. Audi would therefore now be almost forgotten if it hadn’t been for the two-strokes which killed the brand that made them.

MAN B&W 11G95ME-C9.5

Although this article is mostly about cars, we can't write about German engines without mentioning the incredible marine unit produced by MAN (part of Volkswagen) and used in the gigantic 400-metre long, 19,000 container-carrying MSC Jade.

The 11-cylinder two-stroke produces around 103,000bhp at a positively relaxed 80rpm. Its 26,977-litre capacity is approximately 1677 litres greater than that of the Finnish Wärtsilä-Sulzer RTA96-C, which is often (but wrongly) described as the world's largest internal combustion engine.

Mercedes M139

The M139 is a two-litre turbocharged four-cylinder engine fitted to the Mercedes-AMG A 45 hatchback, the CLA 45 fastback and the GLA 45 crossover. It's available with outputs of either 382bhp or 416bhp. In the latter form, it’s said to be the most powerful four-cylinder engine fitted to a production car.

In fact, Mitsubishi developed a 440bhp engine of similar size and layout for a version of the Evo X sold in the UK, but only 40 examples were ever built. Depending on your definition of a production car, the Evo might therefore not qualify, whereas the Mercedes models unquestionably do.

Mercedes M156

The M156 is historically significant because it was the first engine designed from scratch by Mercedes subsidiary AMG, rather than by Mercedes itself. Although the V8 unit measures almost exactly 6.2 litres, the various models fitted with it all had 63 in their titles, including the E 63 AMG (pictured) and, rather improbably, the high-performance version of the R-Class MPV.

The M156 was produced from 2006 to 2011, with outputs of up to 518bhp. The even more powerful M159 derivative was used in the Mercedes SLS AMG sports car.

Mercedes M196

Mercedes created the 2.5-litre straight-eight M196 engine for its W196 Grand Prix car, and enlarged it to 2.9 litres for the 300 SLR sports racer. Technical highlights included direct fuel injection and desmodromic valves, which were pushed shut rather than allowed to return to their closed position by the release of a spring.

In the two years before Mercedes made one of its periodic withdrawals from motorsport, Juan Manuel Fangio (1911-1995) became F1 World Champion in both 1954 and 1955 driving the W196, while Stirling Moss (1929-2020, pictured at the wheel) famously won the 1955 Mille Miglia in the 300 SLR.

Opel CIH

The Opel Cam In Head engine's name is derived from the fact that its camshaft was mounted in the cylinder head rather than the block, but between the valves rather than above them as in a conventional overhead-camshaft layout.

Remarkable for its longevity, the CIH was first used exclusively in Opel models, and later in equivalent vehicles sold by Vauxhall. It made its debut in the Opel Rekord of 1965, and was still being used three decades later in the Isuzu off-roader sold in Europe as the Frontera.

Porsche flat-six

Porsche designed air-cooled flat-four engines for the original Volkswagen, and for its own 356 and 912 models. For the 911, the company added two more cylinders to the design, and thereby created what is widely regarded as one of the world's greatest engines.

Although there were many detail changes - including turbocharging - over the years, the most significant development was the introduction of water cooling in 1997, 30 years after the 911 first went on sale.

Volkswagen EA827

Although the EA827 is now regarded as a Volkswagen Group engine, it actually made its debut in the 1972 Audi 80. It was available for several decades in sizes ranging from 1.3 to 2.0 litres, and used in a great many VWs and Audis, and later SEATs and Skodas.

Most significantly, it powered the first-generation VW Golf GTI (pictured), regarded by some (probably wrongly) as the first hot hatch. Later developments included supercharging (for models wearing the G60 badge) and the fitment of a 16-valve cylinder head.

Volkswagen Type 1

The Type 1 was used for the entire life of the original Volkswagen (nicknamed, but never officially called, the Beetle) from 1938 to 2003, and is one of the world's longest-lived production engines. As well as the Beetle, it was fitted to the Type 2 commercial vehicles (including the Transporter), the Type 3 saloon, the Karmann Ghia sports car and a great many light aircraft.

In those models, its capacity ranged from 985cc to 1.6 litres. A larger derivative, ranging in size from 1.7 to 2.0 litres, was used in the Volkswagen 411 and 412 and the Porsche 914.
