Where Is A Porsche Engine?

The 911’s silhouette and flat engine are frequently the first images that come to mind when someone thinks about Porsche. Every Porsche enthusiast holds these engines in the highest regard. But what makes this specific internal combustion engine design principle so unique?

Fans of this engine type have a soft spot in their hearts for air-cooled flat engines. But feelings only provide a partial picture. The flat engine has a number of intriguing qualities that give it the advantage from a design standpoint in addition to roaring its way into the hearts of many. Its beginnings can be traced back 122 years to Carl Benz’s invention of the flat engine in 1896. Because its two cylinders operated counter to one another, he termed it the contra engine. The original boxer engine was designed to have a displacement of more than 1.7 liters and produce 5 horsepower. The essential design guideline is that the cylinders should be positioned on either side of the crankshaft, level and slightly offset from one another.

The VW Beetle is the ancestor of the flat engines used in Porsche vehicles. Ferry Porsche placed its 26 kW (35 hp), 1.1-liter, four-cylinder engine in his 356-001. Up until the 911 Type 993, all ensuing engines were air-cooled. Without using a turbocharger, the 3.8-liter air-cooled flat engine in the top-of-the-line 911 Carrera RS produced 221 kW (300 horsepower). Performance was increased by two turbochargers to 331 kW. (450 hp).

Flat-six Porsche engine

The Porsche flat-six engine series is a line of mechanically comparable flat-sixboxer engines that have been produced by Porsche since 1963 for almost 60 years without interruption. The flat-fourboxer utilized in the first Volkswagen Beetle has been evolved into the current engine.

The 911 model, Porsche’s flagship rear-engined sports car that has only employed flat-six engines since 1963, is most frequently associated with the flat-six engine. Up until 1999, when Porsche began using water-cooled engines, the engines were air-cooled.

Porsche unveiled the third iteration of the 997 GT3 RS in April 2011 with a larger 4.0-liter engine that produces 500 PS (368 kW; 493 hp). With their 911 (997) GT3 RS 4.0, which debuted in 2011, they debuted the naturally aspirated 4.0-liter flat-six engine, the largest engine available in a street-legal 911. The engine itself makes use of an RSR crankshaft with larger stroke specifications (from 76.4 mm to 80.4 mm). A power-to-weight ratio of 365 horsepower per ton was achieved thanks to this modification, which increased the output to 500 PS (368 kW; 493 hp) at 8,250 rpm and 460 Nm (339 lbft) of torque at 5,750 rpm. There were just 600 automobiles made. The engine’s 493 horsepower (368 kW) and 123.25 horsepower (92 kW) per liter output make it one of the most potent six-cylinder naturally aspirated engines in a production vehicle.

The 1970–1972 Porsche 914/6 (mid-engine), the 1986–1993 Porsche 959 (rear-engine), and the 1996–2021 Porsche Boxster/Cayman are further Porsche models powered by flat–six engines (mid-engine).

What Justifies the Porsche 911’s Rear Engine Design?

Find out why Porsche is adamantly sticking with the 911’s rear-engine architecture.

The Porsche 911 has been renowned for its rear-engine design for many years. Since its beginnings more than 50 years ago, the classic German sports car has had its engine positioned behind the rear axle. This design was carried over from the 356 before it. There are a few exceptions, especially the current 911 RSR and the 911 GT1 from the late 1990s, both of which have mid-engine layouts. Even so, the 911’s rear-engine configuration is a key component of its design. However, is there a reason the company adamantly sticks with this choice?

After all, the location of the engine influences the interior space, functionality, acceleration, braking, weight distribution, and driving dynamics, making it one of the most important choices an automaker must make when building a car. Let Engineering Explained, a popular YouTube channel, and your instructor Jason Fenske educate you.

Fenske compares four scenarios between a rear- and front-engined automobile while explaining the advantages and disadvantages, and uses these comparisons to demonstrate Porsche’s engineering reasoning. The 911 benefits from improved weight transfer when braking with less weight on the front axle, but acceleration benefits from the extra weight at the rear axle. For the past 30 years, Porsche has been producing all-wheel drive 911s, which, according to Fenske, is the best configuration for a rear-engined sports vehicle since the rear-wheel bias keeps it tail-happy and frees the front wheels to handle braking and turning. Look no further than the rear-engined, 700 hp GT2 RS, which set a new lap record at the Nurburgring last year, if you’re still not convinced that this is the best arrangement.

The Purpose of Porsche Flat Engines

The fundamental essence of what distinguishes a Porsche are the recognizable flat-six engines.

People typically picture the classic 911’s silhouette when they think of Porsche, paired with a flat engine design. This design formula was first used in 1896, more than a century ago. But this ongoing practice isn’t just sustained by a sense of nostalgia.

From a performance standpoint, the flat engine combines the greatest features of Porsche’s rear-engine and rear-wheel-drive vehicles. Additionally, the flat layout improves handling, cornering, weight distribution, and engine balance. However, the retirement of this famous Porsche engine is unavoidable given the all-electric future.

August 2022 update: More details on the recognizable flat engines that make Porsche the most sought-after sports car manufacturer have been added to this article. With the advent of electrification, we have also provided a look into the future and potential destruction of these legendary engines.

Where does the engine of a Porsche Cayman reside?

The Sports Car with a Mid-Engine The 718 Cayman obtains dynamic cornering characteristics thanks to its low and central center of gravity, which is achieved with an engine placed no more than 12 inches behind the driver.

Where is the Porsche 911’s engine?

The 911’s twin-turbo 3.0-liter flat-six cylinder engine is located in the back of the vehicle. The standard Carrera produces 379 horsepower; the S produces 443; and the GTS produces 473. While a tremendously quick-shifting eight-speed automatic transmission is standard on every model, a sweet seven-speed manual transmission is also available, but you’ll have to spend more money for a S or GTS to obtain it. Although the coupe and cabriolet come standard with rear-wheel drive, all-wheel drive is an option for four-season, high-performance driving. Only the Targa has all-wheel drive. Testing of the original Carrera as well as several iterations of the more potent Carrera S demonstrated both the car’s prowess on the racetrack and its exceptional grip in challenging driving conditions. Every 911 has incredible acceleration, regardless of the application, especially when the joyously effective launch control is used. When equipped with the eight-speed automatic transmission at our test track, the GTS model accelerated to 60 mph in just 2.8 seconds; when fitted with the seven-speed manual transmission, the 911 GTS achieved a slightly slower time of 3.2 seconds. Porsche’s optional sport exhaust system adds a richer engine note, further enhancing the experience. The 911 is still comfy and better to drive than ever, which is the best part. The coupe and convertible offer more cornering grip and stability, and the steering is communicative and beautifully straight. Despite the 911’s incredible body control, which enables drivers to easily switch between leisurely drives and exhilarating romps, the ride quality is nevertheless surprisingly supple.

Why is the Porsche’s engine in the back?

Rear-engine vehicles appear to be absurd. A lot of careful engineering is needed to prevent a car from becoming harder to turn in and more likely to enter oversteer when it has so much weight behind the rear axle. Even so, the Porsche 911 continues to rank among the best-driving automobiles ever produced. How come? It turns out that rear-engine vehicles offer a number of noteworthy benefits.

The distribution of weight is the key to everything. In a 911, the rear-driven axle carries more weight than in a typical sports car, which increases the strain on the rear tires and increases traction under acceleration. Since it won’t have to pass via a driveshaft, that power will also be able to reach the ground more quickly.

Also, rear-engine vehicles benefit from better brakes. Braking performance is determined by how evenly the braking force is spread across all four tires, as opposed to acceleration, which prioritizes as much weight over the driven axle as feasible. A front-engine car will transmit the majority of its weight to the front because that is where the most of the weight is already, but a rear-engine car will distribute its weight more evenly front-to-rear.

But they are only a few advantages of a rear-engine design. Let Engineering Explained’s Jason Fenske outline all the benefits of placing the engine behind the rear axle.

Which Porsches have front-engine designs?

Front-engined water-cooled Porsches from 1977 to 1989 are essentially the only deals that can be found on an entry level, attend-college-and-have-a-job budget. the 924, 924 Turbo, 924S, 944, and 944S in particular

Do all Porsches have back-mounted engines?

The engines are not always located in the back of Porsche automobiles. The rear engine configuration is one of the most identifiable aspects of the Porsche design philosophy. Better traction, simpler steering, and superior handling are all made possible by the design.

Although some of Porsche’s most well-known models, including the 911, have rear engines, not all Porsche cars have.

Records indicate that the engines of early racecar versions, including the Porsche 550 Spyder, Porsche 718, and Porsche 904 Carrera GTS, were mounted in the center of the vehicle.

Mid-engine designs are common in contemporary sports vehicles like the Porsche Cayman GT4 and Porsche Carrera GT.

The modern SUVs and sedans are the only other Porsche models without rear engines (Cayenne, Macan, and Panamera).

Do Porsche cars have front or rear engines?

The axiom at Zuffenhausen hasn’t always been that the only authentic Porsche is a rear-engined, air-cooled Porsche. In actuality, several of Porsche’s illustrious sports racers, like the 550 Spyder and 718 RSK, as well as the first Porsche ever constructed in 1948 were mid-engine designs.

Is the Porsche mid-engine or rear?

Porsche introduced the mid-engine to series production with the 914 fifty years ago. The Porsche 718 Cayman GT4 and the 718 Boxster Spyder are two of the most recent models with the engine in front of the rear axle.
