They are or were used in: the Volkswagen Beetle, some Porsche and Subaru cars, many BMW and Honda motorcycles, and aircraft engines ( for propeller driven aircraft ), etc.

To this day, no Porsche has ever used an EA827-based engine.

This design marked a major change in direction for Porsche ( started with the introduction of the Porsche 924 in 1976 ), whose cars had until then used only rear-or mid-mounted air-cooled flat engines with four or six cylinders.

Porsche Engineering Group also helped Harley-Davidson design the Revolution 60-degree v-twin water-cooled engine and gearbox that is used in their V-Rod motorcycle.

However, not all this work was wasted, as the chassis Porsche designed for the Tiger I was used as the base for the Elefant tank destroyer.

1952 Porsche 356 K / 9-1 Prototype In post-war Germany, parts were generally in short supply, so the 356 automobile used components from the Volkswagen Beetle, including its internal combustion engine, transmission, and suspension.

The two companies collaborated in 1969 to make the VW-Porsche 914 and 914-6, whereby the 914-6 had a Porsche engine, and the 914 had a Volkswagen engine, in 1976 with the Porsche 912E ( USA only ) and the Porsche 924, which used many Audi components, and was built at Audi's Neckarsulm factory.

Porsche 944s were also built there, although they used far fewer Volkswagen components.

The front-engine, rear wheel drive arrangement was normal for most other manufacturers, but it was unusual for Porsche having previously only used mid-or rear-mounted engines of a boxer configuration, all of which had been air-cooled.

In 1984 VW decided to stop manufacturing the engine blocks used in the 2. 0 924, leaving Porsche with a predicament.

Ferdinand Porsche used this setup in the early 20th century in racing cars, effectively inventing the series-hybrid arrangement.

The Porsche suspension were later used on a few of the later Jagdtiger tank hunters.

Porsche also used the VW engine in the early Porsche 356.

This engine was an evolution of the Porsche flat-8 boxer engine and used identical cylinders to those found on the 908, but differed in that it used a V12 type crankshaft.

This inline engine configuration is the most common in cars with a displacement up to 2. 4 L. The usual " practical " limit of the displacement of inline-four engines in a car is around 2. 7 L. However, Porsche used a 3. 0 L four in its 944 S2 and 968 sports cars, the International Harvester Scout was available with a 3. 2 L inline four from 1965 until 1980 and Rolls-Royce produced several inline-four engines of 2, 838 cc with basic cylinder dimensions of diameter and stroke ( Rolls-Royce B40 ).

The car's designers had intended that the headlights could be retracted, with the lenses facing skyward when not in use ; a similar arrangement was used many years later on the Porsche 928.

The Maus was designed from the start to use the " electric transmission " design which Ferdinand Porsche had used in his unsuccessful attempt to win the production contract for the Tiger.

Similar to designs of European cars such as Porsche, Volkswagen, Mercedes-Benz and others it used coil springs at all four wheels with independent rear suspension arms incorporated at the rear.

Journalist David E. Davis, in a 2009 article in Automobile Magazine, noted that despite Nader's claim that swing-axle rear suspension were dangerous, Porsche, Mercedes-Benz, and Volkswagen all used similar swing-axle concepts during that era.

Porsche substantially revised the suspension, replacing the rear torsion bars with coil springs and shock absorbers.

Stemming from the design of an integral ' roll bar ', it was still a new concept in the automotive industry, preceding the 1966 Porsche 911 Targa, which popularized it ( and established the name ).

Porsche supplied an 3, 1L engine with 750-800 hp at 1, 5 bar boost for 91 000 DM in total.

Well in his 50s, Asch has returned to the German Porsche Carrera Cup, where he raced until 2003, bar a one-off race during the 2004 season.

In addition, Porsche installed manually adjustable lightweight Recaro racing seats rather than the standard power-operated leather buckets ( also manufactured by Recaro ), a revised suspension system optimized and lowered by 20 mm for possible track use, 17-inch wheels ( also slightly wider to accommodate wider tyres ) rather than the 16-inch as found on the Coupe and wider tires, 225 front and 255 rears rather than 205 and 245 respectively.

With the no frills approach meaning less weight, as well as the optimising of the suspension, Porsche could focus media attention on the Club Sport variants fast road and track abilities.

While the 356's body was an original design by Porsche employee Erwin Komenda, its mechanicals ( including engine, suspension and chassis ) were derived from the Volkswagen.

Porsche already preferred the flat-four engine, and selected a swing axle rear suspension ( invented by Edmund Rumpler ), while Zündapp insisted on a water-cooled five-cylinder radial engine.

None of the issues Nader raised were problems among owners of the Porsche 911, which had the same layout and similar suspension, nor with the less powerful Volkswagen Type 1 Beetle.

The 718 was a development of the already successful Porsche 550A with improvements being made to the body work and suspension.

The Porsche 904 rode on coil springs ( the first Porsche not to use trailing arm front and swingaxle rear suspension ), with unequal-length A-arms in front.

Yet, Formula One used lighter 13-inch wheels, and Porsche had already used Team Lotus suspension parts in earlier years.

When developing the suspension system the facility of electro-hydraulic kinematics and compliance at Anthony Best Dynamics was employed to measure the performance of the suspension on a Jaguar XJR16, a Porsche 928S and a Honda NSX to use as references.

The Porsche Carrera GT's carbon-ceramic ( silicon carbide ) disc brakeNotable technology includes a pure carbon fiber monocoque and subframe, dry sump lubrication and inboard suspension.

The Weissach axle ( pronounced ' Vise -' as in ' advise ' and '- ach ' with guttural ' ch ') is a special rear suspension arrangement devised for the Porsche 928.

Toyota engineers ( including Dr Kumabe ) had visited Germany before World War II and had studied Porsche and Volkswagen designs ( independent suspension, aerodynamic bodies, backbone chassis, rear-mounted air-cooled engines, economical production cost ).

In circuit racing, the new car was very hard to master, though, due to the swing axle rear suspension design initially adopted by Porsche ( relatively advanced for its day, it is now utterly obsolete because of its many problems ).

The longest surviving flat-six-engined model, the Porsche 911, is a rear-engined sports car with acceptably compromised interior room and a long history of suspension development to utilize the characteristics of the drivetrain layout.

As a suspension or steering failure was suspected, the BMW team with Hubert Hahne and Dieter Quester withdrew from the race, as did Mitter's teammate at Porsche, Hans Herrmann.

These problems were evident on the Mercedes-Benz 190SL and 300SL, Porsche 356, Triumph Herald, Vitesse and Spitfire, Tatra T603, Renault Dauphine, Volkswagen Beetle ( until rear suspension modifications, c. 1967 ) and others.

Aftermarket roll-inducing springs from the likes of SCAT, also called camber compensators, are available for Porsche, VW and early Corvairs, which reduce oversteering tendencies at the cost of increasing suspension harshness.
