Dear Readers,

Curiosity certainly got the better of ourengineers, for example, when they devel-oped the condensation test stand forADA. Porsche Engineering made a sig-nificant contribution to environmentalprotection here, which will benefit all theautomotive manufacturers involved. Natu-rally, environmental protection is a parti -cu larly important factor in our day-to-daydevelopment work.

In the second last issue of the Engineer-ing Magazine, we told you all about thehistoric Lohner Porsche with its Porschehybrid technology from the year 1900.And because the Porsche developershave been hard at work since then, wecan now present the current Cayennehybrid in this issue.

The question in relation to the new 911series was: Is it possible to improve onan already perfect sports car? Thisappeared to be a real challenge for thedevelopers in Weissach. They set to work.What they came up with is being greetedenthusiastically by international technicalpublications. Read on to find out why the

Complete vehicle development – something entirely different

The engineers at Porsche Engineering cannot conceal their origins, even when it comes

to industrial developments – including speed counters. A search for development

parallels for a somewhat unusual “vehicle”.

Admittedly, the development of a “grillcar” is somewhat of an exception forPorsche Engineering. With the result thatthis grill has little in common with itscommercially available cousins and farmore in common with a Porsche car,because colleagues from Porsche Designhad a hand in designing it. And whatabout the mechanics? They came fromPorsche Engineering. When we weredone, even we had a little respect. Notonly does the new outdoor kitchen offer

beauty, style and excellent functionality,which you expect from Porsche DesignStudio, it also features the Crossray®

burner technology developed and pa t -ented by Grandhall. The resulting “grillcar” is a masterpiece – highly functionaland stylistically pure.

Parallels with the sports car

And since this is Porsche, we specificallylooked for parallels with the sports car

for our development project. And wefound them. Even the first sketches byPorsche Design opened up a new era forthe Grandhall outdoor kitchen. Whenyou’re the Porsche of barbecues, youneed the mechanics of the sports carmaker too. Our engineers from PorscheEngineering used a slim stainless-steelbody as the bodyshell. The modular-designed system means that the kitchentrolley can be used both as a mobilecooking station and a mini-kitchen.

New framework structure forgreater hold

With a new inner framework structure,we have given it a secure hold – stabil-ity for guaranteed roadholding. The eyeis drawn straight to the domed sheet-metal sliding roof giving rise to an imme-diate open-top feeling. After all it is, infact, still summer. The perfect time forour outdoor kitchen. The lever mecha-nism of the “cabriolet hood” reminds usof something. It opens smoothly, quietly,almost silently. It is a succinct lesson inelementary physics. The calculation ofspring strength and paths, friction cal-culations and materials all combined toproduce a perfect, force-optimised sys-tem for opening the top. Under the sliding roof, we see a grill – we ask our-selves: how long does our steak have tosit still here until it is perfect? Tempera-tures had to be taken for this and theengineers pushed the small mobilekitchen to its limits time and time again.Once satisfied, we nod in approval: a jobwell done!

Speed range – including display

We play with the centre console and aredelighted with the simple, elegant knobs.The switch panel shows which speedrange is currently active – in otherwords: whether or not the burners are intop form. There’s also a clock for thecook. Time to chance looking at theside: surprisingly, our Grandhall has a“trailer hitch” on both sides. Just like ourExclusive/Tequipment range, there’salso a wide choice of attachment optionshere. The gleam of silver stainless steelshines on all components, be it the cook-ing drawer or other details. Fine, blackstone elements further highlight thePorsche Design trademark. Almoststraightaway, the stone look reminds usof a freshly asphalted section of race-track. And we wouldn’t be Porsche if weweren’t fond of “stepping on the gas”here at least. And look there, under thegrill, we find the engine, the heart of thenew master grill. The heart is behind asliding door. It beats faster and hotterand you wonder a little why these burn-

ers don’t need cooler grills. With theCrossray® infrared burner technologypatented by Grandhall, the outdoorkitchen boasts the most sophisticatedsystem available today – darting flamesand choking smoke are a thing of thepast. Unlike traditional burners, which liedirectly under the cooking zone, theinfrared burners at the sides heat thecomplete grill area evenly. Outdoor cook-ing is now child’s play for everyone!

Efficient processes for more added value

We look down under the Grandhall. Wesee small wheels fitted with the finestbrakes. The Porsche engineer had mobil-ity in mind here. Freedom of movement– even for a kitchen. Certainly, it is a com-pact kitchen, but because of this, thepassion for detail was particularly im -portant. The wheels are break-proof andweather-resistant. And that ends ourcomparison with Porsche development,where engineers work passionately everyday developing something new for you.

with.” Our conclusion: With its finely pol-ished granite surfaces and electronicinstruments, the new outdoor kitchen isan utterly elegant and functional innova-tion, which is as much at home in thefinest gardens of the world as it is a largeroof terrace. The developers at PorscheEngineering are very happy.

And now? We’re hungry and have justcalled our Porsche colleague ReginaSchaan, two-time German master griller,who has the following recipe for you:

Hold on! One more thing: As at Porsche,our outdoor kitchen was optimised forproduction, which makes the fitters atGrandhall Production happy becausethey now have less to do thanks to leaner,more efficient pro cesses. Wilbert Kroes,Sales Manager at Grandhall Europe:“Working together with Porsche DesignStudio and Porsche Engineering was animmensely inspiring experience for us. Itwas exciting to see how perfect designand engineering skills were combined toform one product that we are so familiar

It’s what’s inside that counts

Is it actually possible to make a seemingly perfect sports car even better? The new 911

generation – with technical highlights designed specifically for greater power using less

fuel. Improved efficiency for a superior look.

The new Porsche 911 taps into the longtradition of the 911 model series. Itsdesign has been carefully enhanced, with-out changing the classic shape. It reflectsthe quality of the further technologicaldevelopment of the drive system. The

slightly larger, outer air intakes give the911 a superior look and highlight the highperformance potential of the new genera-tion. Its looks will certainly catch youreye. And the technology? It makes our engineers’ heart beat faster and leaves

nothing to be desired. What’s new, forexample, is the unique Porsche Doppel -kupplung (PDK). Another highlight: thecompletely redesigned engines withdirect fuel injection enable a significantimprovement in performance while at
