When people think of Porsche, the first thing that comes to mind is often the silhouette of the 911 – and the flat engine. These engines are very close to every Porsche devotee’s heart. But what is so special about this particular design principle for an internal combustion engine?
The air-cooled flat engine has a special place in the hearts of its fans. But emotions only tell half the story. As well as revving its way into the affections of many, the flat engine has many interesting features that give it the edge from a design point of view. Its history dates back 122 years to 1896, when Carl Benz invented the flat engine. He called it the contra engine because its two cylinders worked in opposition to one another. This first boxer engine was intended to have a displacement of over 1.7 litres and deliver 5 hp. Its underlying design principle – both then and now – is that the cylinders should lie flat and slightly offset to each other, on opposite sides of the crankshaft.
The Porsche family tree of flat engines can be traced back to the VW Beetle. Its 1.1-litre, four-cylinder engine delivering 26 kW (35 hp) was installed by Ferry Porsche in his 356-001. Further engines followed, all of which were air-cooled until the 911 Type 993. In the top-of-the-range 911 Carrera RS, the 3.8-litre air-cooled flat engine achieved 221 kW (300 hp) without turbocharging. Two turbochargers boosted performance to 331 kW (450 hp).
The ideal choice for sports cars
The air-cooled flat engine is lightweight and flat, making it the ideal choice for sports cars, and particularly low designs are possible as the cylinders are lying flat. This lowers the centre of gravity, allowing for a sportier and more dynamic style of driving – and not just when cornering. If the flat engine is installed at the rear as in Porsche vehicles, traction is improved because the weight of the engine rests on the drive axle. Until all-wheel drive vehicles conquered the roads, Beetle and Porsche drivers agreed that a car with a rear-mounted engine was by far the best choice for winter conditions. The opposite is also true: When braking, the weight of a rear-mounted engine allows more braking force to be transferred to the rear wheels.
The flat engine – and especially its six-cylinder variant – is particularly smooth-running, with no free moments or free forces. The crank mechanism is ideally balanced, allowing short-stroke sports engines to cruise along at high speeds without excessive strain.
The 3.8-litre six-cylinder twin-turbo boxer engine of the 911 GT2 RS
One of the most characteristic features of the Porsche six-cylinder flat engines is the drop in fuel consumption as engine power increases. The concept underlying the flat engine involves a consistent lightweight construction, a low centre of gravity, outstanding revving ability and a high specific output thanks to advantageous charge cycles. All 911 engines need to be sporty as well as suitable for everyday use.
As a basic rule, it takes more effort to manufacture a flat engine than an in-line engine because a greater number of parts are needed. The flat engine needs two banks of cylinders with a valve train, plus cooling or injection. The flat engine is a particularly good candidate for air cooling because the individual cylinders are located far apart from each other and can therefore benefit from a direct flow of cooling air. The fact that the 911 flat engines have been water-cooled since the 996 model series is primarily a result of the four-valve technology. Four valves are a prerequisite for cutting fuel consumption and exhaust emissions while also boosting performance.
But this is only a point of interest for fans of water-cooled flat engines. No club with this name exists yet, but it surely will one day, when these engines stop being the latest technology and become part of history.
Real-time remote assistance improves efficiency and can reduce service resolution time by up to 40 percent. Use of augmented reality in technical services for an even better service quality and customer experience
Atlanta, Georgia. Porsche Cars North America, Inc. (PCNA) today announced the introduction of "Tech Live Look," an Augmented Reality (AR) technology designed to improve technical services at Porsche dealerships in the United States.
"Tech Live Look" uses the AiR Enterprise™ software platform from Atheer, Inc., a leading provider of AR solutions, in conjunction with lightweight smart glasses. These high-tech spectacles feature the latest in projection technology and come equipped with a high-resolution, auto focus camera that shows even fine details such as threading on screws. The glasses include a powerful LED to illuminate dark spaces in the engine compartment or under the car.
How does this technology work? When a service technician at a dealership in Los Angeles dons this specialized eyewear and connects through the software with the Atlanta-based Porsche technical support team 2,200 miles away, it allows the support team to see exactly what he is seeing, in real time. This "see what I see" video-conferencing capability with instant access to remote experts allows both parties to quickly identify and resolve technical issues. It can also help decrease service resolution time by up to 40 percent, based on the findings of a pilot program undertaken in July 2017 at eight Porsche dealerships in California, Florida, Indiana, New Jersey, and Washington, along with one in Canada.
"Tech Live Look" can do much more than just provide real-time video capability. It allows the technical support team to take screen shots or send technical bulletins and instructions onto the projection surface of the glasses while the service technician is working on the vehicle. This type of information exchange is far more efficient than sending emails and photos or explaining complex technical issues over the phone.
"Our main goal is to provide a better overall experience for our customers. Tech Live Look allows us to be more efficient and helps get vehicles back in the hands of our customers faster, all while still delivering exceptional service quality" explained Klaus Zellmer, President and CEO of PCNA.
"Tech Live Look" will officially launch in dealerships in North America in 2018.

Atlanta, Georgia. The new 2018 911 Turbo S Exclusive Series Coupe from Porsche is the most powerful 911 Turbo S ever. The Coupe makes 607 horsepower and is limited to 500 units worldwide. In addition to an increase of 27 horsepower, the 911 Turbo S Exclusive Series distinguishes itself from other 911 Turbo S models with its unique design, specialty materials, and luxurious details. The sports car is being meticulously finished by hand in the new Porsche Exclusive Manufaktur at Porsche AG's headquarters in Stuttgart-Zuffenhausen. Previously known as "Porsche Exclusive," the in-house workshop specializes in customization and is responsible for limited-edition vehicles. For the first time ever, Porsche customers can have the optional matching chronograph from Porsche Design configured in the same specification as their car.
Increased power and performance
The 3.8-liter, twin-turbo flat-six engine with a power kit delivers a maximum torque of 553 lb.-ft. between 2,250 and 4,000 rpm. This results in the 911 Turbo S Exclusive Series Coupe accelerating from 0 to 60 mph in 2.8 seconds, and it takes 9.6 seconds to cross 124 mph making it 0.3 seconds faster than the standard 911 Turbo S. The top track speed is 205 mph. The 911 Turbo S Exclusive Series comes standard with 20-inch center-lock wheels painted in black, with highlights carefully finished in Golden Yellow Metallic using a new laser technology. For the first time, the brake calipers for the Porsche Ceramic Composite Brake (PCCB) system are available in black with the Porsche logo in Golden Yellow Metallic. The active sports chassis with Porsche Active Suspension Management (PASM) and the Sport Chrono package are included as standard. Rear-axle steering and Porsche Dynamic Chassis Control (PDCC) further enhance handling and stability.
What makes the 911 Turbo S Exclusive Series Coupe so distinctive is the exclusive Golden Yellow Metallic paint finish and various carbon fiber components, including the front trunk lid, roof, and side skirts. The two carbon-weave strips that contour the roof and front trunk lid accentuate the sporty look of the car. The rear view is characterized by the rear wing of the Turbo Aerokit, a new rear fascia, and the exhaust system with twin tailpipes which are finished in black. The fenders are decorated with Porsche Exclusive Manufaktur plates. In addition to Golden Yellow Metallic, the vehicle is offered in other select exterior colors.
The interior is both elegant and unique. The 18-way adjustable sports seats are covered in perforated leather. The inside layer has two stripes in Golden Yellow, creating a unique effect. The seams and the Turbo S lettering stitched into the headrests are also finished in Golden Yellow, and the roof lining is made of Alcantara with a Golden Yellow double-stripe look. Fine copper thread is integrated into the trim strips of the carbon fiber interior package. The plate featuring the limited-edition number on the passenger's side underlines the car's exclusivity. The door sill guards, also finished in carbon fiber, include illuminated Exclusive Series lettering.
For more than 30 years, Porsche customers have been able to enjoy extensively customized individual components. With the introduction of this new limited production vehicle, Porsche is beginning a new chapter: Porsche Exclusive will now be presented across the globe with the new "Porsche Exclusive Manufaktur" brand. This in-house workshop specializes in custom Porsche modifications. The range of services available also includes customer consultation, developing special equipment options for each model range, and producing limited production cars.
Exclusive Chronograph from Porsche Design to match the vehicle
The Porsche Design Chronograph 911 Turbo S Exclusive Series represents the first occasion where Porsche Design has released a Chronograph for limited production car customers with design features corresponding to those used in the vehicle. The exclusive Chronograph combines the characteristic features of Porsche Design watches with the character of the 911 Turbo S Exclusive Series Coupe.
