N ot makes you inventive. And the need was great. After the Peugeot group had to leave the LMP1 prototype sport Knall auf Fall after five years due to a dramatic financial emergency in January 2012, the sports department in Vélizy was radically shrunk to health. But less than six months later the board members complained: Why is the sports department no longer producing any image-promoting successes?

Do something, but it shouldn't cost anything

According to the motto “Do something, but it shouldn't cost anything”, brains Peugeot sports director Bruno Famin about an image-enhancing but at the same time cost-effective solution. The result was Pikes Peak, the legendary hill climb in the US state of Colorado.

There were three reasons for using it on Pikes Peak: First, Ari Vatanen had already conquered the mountain in 1988 with a brilliant Peugeot, so there is one History. Secondly, the top class is technically unlimited, which means that the engineers can let off steam without worrying too much about difficult regulations. And thirdly, you could continue to use parts from the LMP1 program in this way - and thus also save money on spending.

A monster stuck together

At the end of June, the Peugeot 208 T16 proved on Pikes Peak that the bill also works. Under the project management of Jean Christophe Pallier, a two-meter-wide poison cube was created, some of the components of which come from the attic or the cellar dungeon.
The 3.2-liter V6 biturbo engine, for example, last rattled in 2003 in Le Mans, in a Pescarolo C60 . After ten years of hibernation, the engine was revived with modern turbo technology from Garrett. Now the biturbo, which is allowed to run on Pikes Peak without restrictors, has an output of 875 hp. This means that the power-to-weight ratio is almost exactly one kilo per hp.
Originally, a second use of the LMP1 diesel engine in the Peugeot 208 T16 was even considered, “but firstly, the lead time for an adaptation to the chassis would have been too short, and secondly We dealt with problems with weight and packaging, ”reports project manager Pallier.
When rummaging through the basement, the technicians found the suspensions and brakes from the LMP1 car, and the rear wing and the air snorkel for the engine also fitlike a glove. The original modular principle also provided for the use of the LMP1 hybrid drive, but unfortunately the spare parts could no longer be found in full. This is a shame, because using hybrid technology would have made sense from a technical point of view: the power output of electric machines does not suffer from the altitude, unlike internal combustion engines.

130 HP less at the destination

'For every 100 meters of altitude, the engine loses one percent of power,' calculates Bruno Famin before. We continue to calculate: The start of the mountain test is at 2-865 meters, the finish at 4-301 meters. Ergo, the 875 hp V6 engine in the valley loses a good 15 percent or 130 little horses by the way to the finish line.
At some point, the picking up of parts will come to an end, then resourceful mechanics and engineers have to lend a hand. A newly manufactured tubular frame chassis houses the engine, driver and suspensions. Because the 208 T16 has all-wheel drive, the six-speed Xtrac transmission from the LMP1 Peugeot could not be adopted. When it comes to tires, on the other hand, Peugeot doesn't have to dig into the past, but can even anticipate the future.
The 208 T16 uses Michelin LMP1 tires, which will only be used in Le Mans in 2014. Just a reminder: When Ari Vatanen and Walter Röhrl once climbed this mountain with madness, it was a gravel pass road, but since 2012 the 19.9 kilometer special stage has been completely paved.

How do I suspect aerodynamics?

Since the beginning of 2013, the mountain cube has been in test operation, as you can hear quite successfully. But Monsieur Pallier has one tiny concern: “During the mountain test on Pikes Peak, the car has to cover a speed range of 50 to 240 km /h, and above 100 km /h aerodynamics play a decisive role. We are actually well prepared because we generate over half of the total downforce from the underbody. ”But? 'In order to create an exact route profile, we sent a delegation to the USA, but they came back empty-handed - because the upper section of the route was completely snowed in.'
What Pallier wants to say: Peugeot Sport still doesn't know exactly what exactly awaits you on this mountain. Therefore, the factory team will travel to Colorado at the beginning of June - to finally collect real data.

In an emergency the devil also eats flies

Incidentally, when choosing a driver, Peugeot also implemented the principle of secondary recycling: originally Romain Dumas should have chased the monster from France onto the American mountain, but when Red Bull pulled out the thick checkbook, it was obvious, nine times as much Rallying world champion Sébastien Loeb in front of the cart - because Citroën and Peugeot both belong to thePSA group, so are brothers. Or let's put it this way: In an emergency the devil also eats flies.

At the Pikes Peak International Hill Climb 2013 Loeb set a new record .
