Porsche 919 Hybrid: Dress Rehearsal for Le Mans

M14_0626 The six-hour race in Spa-Francorchamps on May 3rd is only the second event for the new Porsche Team with the highly complex Porsche 919 Hybrid. But, at the same time, it is the last race before the season’s highlight at Le Mans on June 14th/15th. The challenging Spa-Francorchamps circuit in the Belgian Ardennes has several things in common with the Circuit de 24 Heures in Le Mans: a relatively long lap (7.004 kilometres) and impressive full throttle sections. However, the differences in elevation are significantly bigger than in Le Mans. Long uphill sections require the utmost power from the efficient hybrid cars. Every race driver has respect for Eau Rouge. When braking for the chicane after the high speed Blanchimont section, the G forces press the drivers back in their seats. To talk about the weather in Spa, often means touching on a serious topic. According to the FIA World Endurance Championship’s new regulations, the Porsche 919 Hybrid’s systems are allowed to produce (recuperate) 4.78 megajoules of electrical energy per lap in Spa, store it and use it to power the electrical engine on the front axle. 4.78 megajoules correlate to 1.33 kilowatt hours (kWh), which is the common unit of measurement for normal households. Calculating that the six-hour race will be run over 170 laps, each of the Porsche 919 Hybrid cars can produce 226.1 kWh. This is almost the amount of electrical energy a standard household in Germany uses during an entire month in summer. This indicates the new technology’s huge potential for future hybrid driven road cars. M14_0621 The Spa six hours will be green flagged on Saturday, May 3rd, at 14:30 hrs CEST and should finish at 20:30 hrs CEST. The final two hours of the race will be shown live on tv by Eurosport, as well as highlights from earlier on in the race. At the World Championship’s opening round in Silverstone the trio of drivers in car no. 20, Timo Bernhard (Germany), Brendon Hartley (New Zealand) and Mark Webber (Australia), finished third. The no. 14 sister car of Romain Dumas (France), Neel Jani (Switzerland) and Marc Lieb (Germany) failed to score points because of drivetrain problems. Quotes before the race: Fritz Enzinger, Vice President LMP1: “We can build on our Silverstone performance. Even with difficult weather conditions, the new Porsche Team has managed to have a very solid debut. Our drivers were outstanding, and in the pits we made the right calls. But we have to keep our feet on the ground, as there are countless more situations ahead during which we will find ourselves first timers. The second championship round is the dress rehearsal for Le Mans. Our main target for Spa is clearly to finish the race with both Porsche 919 Hybrids.” Romain Dumas (#14): “Spa is one of my favourite circuits. It has great high-speed sections, slow corners, differences in elevation and a great racing atmosphere with passionate fans. I have won quite a few races there – the 24 hours twice, a race in a LMP1 car two years ago and, earlier in my career, a Formula 3000 race. I think we had a good performance in Silverstone and in Spa we will be even better.“ Neel Jani (#14): “Our first entry as a team in Silverstone worked quite well and we have learnt a lot that should allow us to take the next step in Spa. In terms of aerodynamics, again we will only have a small amount of downforce, but we have a good top speed and this should count more in Spa than it did in England. In case it rains again, downforce doesn’t matter anyway. Being the last rehearsal for Le Mans makes the six hours of Spa even more exiting for all of us.” Marc Lieb (#14): “Spa is a downforce circuit and the LMP1 car has a lot more downforce than a GT car. I am very much looking forward to going through Eau Rouge for the first time with the 919 Hybrid. The question, whether you can take this corner flat out or not, is exciting. The circuit has a very beautiful flow to it and is always a challenge. One of the nicest memories of my career comes from Spa, where I won outright in my very first 24 hour race back in 2003.” Timo Bernhard (#20): “Spa is going to be nice. It is a great track, a drivers’ circuit and it has a long sports car tradition. I expect lots of fans there. Not only from Belgium, as it is also easy to get there for the Germans, the Brits, the French and the Dutch. For me it’s only 200 kilometres from home, which means my family will come along. The podium finish in Silverstone gave us an extra momentum to learn even quicker. Plus it gave us championship points. It’s a long time since I have raced for points, as in 2011 we didn’t have a drivers’ championship, so only manufacturers could score.” Brendon Hartley (#20): “I think every driver loves Spa and I do as well. It is one of the best tracks in the world. I have driven all sorts of cars there. In 2012 I made my debut in endurance racing there and finished on the podium. Spa should suit our car more than the Silverstone circuit did. The straights are not quite as long as in Le Mans, but we will see very impressive speeds there. The famous Eau Rouge corner requires a lot of respect and we will see whether we can take it at full throttle or not.“ Mark Webber (#20): “We were all so excited and keen to get the first race out of the way and pull off a clean weekend with qualifying and the race, which went better than we expected. So now going to Spa shortly after the first race is good for us to try and continue the momentum. The dialogue in the team between all the drivers, the engineers and Weissach has been phenomenal when looking for areas where we can keep improving, which is a no brainer as we’ve only done one race. There is a bit of excitement in the camp, but we have our feet on the ground. We haven’t had two cars finish yet, so we’d like to do that and get both the no. 14 and no. 20 home.” M14_0623 The Porsche 919 Hybrid: With two different energy recovery systems the Porsche 919 Hybrid is the most complex race car the sports car manufacturer has ever built, and serves as the fastest mobile research laboratory for future road cars. The lightweight prototype is trimmed for extreme performance and efficiency. Besides the kinetic energy recovery system (MGU-K) under braking, the 919 Hybrid recuperates thermal exhaust energy (MGU-H) when accelerating. The combination of these two systems means a step into unknown territory for Porsche and a unique feature in the entire WEC. When the driver recalls the stored energy from the liquid-cooled lithium-ion battery packs, an electric motor drives the two front wheels. This power adds to the combustion engine (downsizing 2.0 litres V4-cylinder, turbocharged with direct injection) and this way the two systems result in temporary all-wheel drive.   Source: Porsche

OFFICIAL: Boxster GTS & Cayman GTS

Cayman GTS

Porsche Introduces two new top models in the mid-engine lineup:

Boxster GTS and Cayman GTS

The two most powerful and fastest mid-engine sports models from Porsche are ready and raring to go: with uprated engines and excellent PASM chassis the Boxster GTS and Cayman GTS set new benchmarks for sportiness in their segment. The independent front and a modified rear end, blackened bi-xenon headlights – with the Porsche Dynamic Light System (PDLS) as standard – and exterior lettering in silky black gloss are subtle yet unmistakable features of the new top models. The name says it all: at Porsche “GTS” stands for Gran Turismo Sport and has promised outstanding Porsche performance ever since the legendary 904 Carrera GTS dating back to 1963. With the new two-seaters Porsche is renewing its commitment to authentic sports cars for both the racetrack and everyday use.

Boxster GTS

The six-cylinder boxer engines fitted in the new top models are based on the 3.4-litre engines from the Boxster S and Cayman S respectively. Thanks to optimized fine tuning they now deliver an additional 15 hp. This means that the Boxster GTS now has an output of 330 hp, whilst the Cayman GTS delivers 340 hp. Torque has been increased by 7 lb.-ft. in each model: 273 lb.-ft. in the Boxster GTS and 280 lb.-ft. in the Cayman GTS. What’s more, the Sport Chrono package is a standard feature in both mid-engine sports cars. This means that in conjunction with the optional Doppelkupplungsgetriebe (PDK) and the active Sport Plus button, the Boxster GTS sprints from 0-62Mph in 4.7 seconds, whilst the Cayman GTS is even a tenth of a second faster. Both vehicles therefore set new reference values.

Boxster GTS

The Boxster GTS and Cayman GTS combine top driving dynamics with the typical Porsche spread with undiminished ride comfort and exclusive features. For example, the combination of PASM and the Sport Chrono package as standard enables the driver to switch between progressive sportiness on the one hand and long-distance comfort on the other hand at the press of a button. The tyres measuring 235/35 at the front and 265/35 at the rear on 20-inch Carrera S-wheels provide the perfect setup for both. Both two-seaters come with sports seats and leather interiors as standard. Like other GTS models from Porsche they are refined with Alcantara elements.

Cayman GTS

With the new models Porsche is now extending the GTS principle to the Boxster and Cayman. Like the Cayenne GTS and Panamera GTS, these are extremely sporty top models that stand for superior driving dynamics in their segment. The combination of letters originates from the 904 Carrera GTS, a race car dating back to 1963 that could also be registered for use on public roads. In the 1980s and 1990s the 924 GTS and 928 GTS cultivated this principle. It was reborn in 2007 in the form of the Cayenne GTS, and was subsequently also implemented in the 911 series and the Panamera.

The Boxster GTS is priced from $73,500 and the Cayman GTS is priced from $75,200, excluding destination charges of $995. Both models will be available for delivery this summer.

Porsche Replacing Engines in the 911 GT3

After numerous weeks of uncertainty, Porsche has come up with a solution to the issue regarding the new 991 Series GT3: Replace the engine. This is the corrective action derived from intensive internal analyses that were initiated in response to two engine fires. Recently, its latest high-priced sports car, the 911 GT3, was recalled due to risk of engine fires. According to the report, the fires were found to have been caused by a loose fastener on the connecting rod. The loosened connecting rod then could damage the crankcase, which cause oil to leak. The leaking oil can cause the fire. 911 GT3 Porsche said Tuesday that it will be replacing the engines of all 2014 model year 911 GT3s. Although there were no crashes or injuries due to the issue, it was considered so serious that Porsche told owners in February to park their cars and don’t drive them until it came up with solution. Porsche is not saying how much its expensive recall will cost, but to date, 785 vehicles worldwide are included in the recall. About 400 are in the U.S., but only half of them have been delivered to customers. The rest are on dealers lots or in the supply chain. The new engines will come with improved, more secure fasteners. Porsche points out that no other 911 models or other model series are affected by this action.   Source: Porsche

Porsche Captures Both GT Classes in Classic Sebring Win

Tudor United SportsCar Championship, Round 2: 12 Hours of Sebring, USA

Factory drivers Patrick Long (USA), Michael Christensen (Denmark) and Joerg Bergmeister (Germany) have won the 62nd Annual Mobil 1 Twelve Hours of Sebring GT Le Mans (GTLM) class in the No. 912 Porsche North America Porsche 911 RSR.

M14_0182The victory gives the new Porsche works program wins in both of North America’s premier two sports car racing events; the Rolex 24 At Daytona in January and today’s 12 Hours of Sebring. The No. 912 held off a field of factory efforts from the class pole position. However, the race came down to a final 20-minute sprint after a late race caution flag packed the field for a last push to the checkered flag in the second event of the Tudor United SportsCar Championship season. Bergmeister, behind the wheel for the final stint, out-distanced the field to give new Porsche’s 911 RSR victories at the three legendary racetracks of Sebring International Raceway, Daytona International Speedway and at the 24 Hours of Le Mans.

M14_0172The victory is Bergmeister’s fourth at Sebring and Long’s second. It was a first for Christensen who also scored his first career pole position as a Porsche factory driver this weekend.

The story for the No. 911 Porsche North America Porsche 911 RSR was set early in the race. The car raced by Richard Lietz (Austria), Nick Tandy (Great Britain) and Patrick Pilet (France) was involved in a second-hour incident that damaged the nose of the Rolex 24 At Daytona-winning entry. Repairs dropped the car six laps back at the time and to last in the GTLM class. Once back on track the team fought to the close of the 12 hours finishing ninth, four laps behind their race-winning teammates.

M14_0170Team Falken Tire debuted the first customer Porsche 911 RSR competing in the world with a strong performance. Factory drivers Wolf Henzler (Germany) and Marco Holzer (Germany), joined with Bryan Sellers (USA), ran to fifth in class from their starting position of ninth.

Porsche Unveils 919 Livery For 2014 LeMans

At the Geneva International Motor Show, the new Porsche 919 Hybrid is celebrating its world premiere for the top category of the 2014 World Endurance Championships (WEC). The innovative hybrid prototype will be joined by the Porsche 911 RSR at the Porsche exhibition area in Geneva as well as at all eight races of the WEC series, whose season highlight will certainly be the 24 hours of Le Mans. 919 Hybrid Porsche 919 Hybrid: Cutting-edge technology benefits production cars Matthias Müller, Chairman of Porsche AG: “Crucial in the development of the Le Mans prototype were the newly created and revolutionary racing rules for this class as they relate to energy efficiency. In 2014, it will not be the fastest car that wins the World Endurance Championship series and the 24 hours of Le Mans, rather it will be the car that goes the furthest with a defined amount of energy. And it is precisely this challenge that carmakers must overcome. The 919 Hybrid is our fastest mobile research laboratory and the most complex race car that Porsche has ever built.” The exceptional efficiency of the Porsche 919 Hybrid is the result of a carefully balanced overall concept. The sum of all of its individual components forms an effective unit: from the combustion engine to the energy recovery systems, chassis and running gear, aerodynamics and driver ergonomics. The combustion engine is a compact V four-cylinder petrol engine that also serves as a load-bearing member in the chassis. It is a frontrunner of the future-oriented downsizing philosophy features two litres of engine displacement, direct fuel injection and mono-turbocharging, the engine that turns at speeds up to 9000 rpm. The compact engine outputs around 500 hp. In addition, the Le Mans prototype has two energy recovery systems. Fundamentally new here is a system that recovers thermal energy from exhaust gases via an electric generator driven by the exhaust gas stream. The second hybrid system has the functionality familiar from the 918 Spyder. Here, a generator on the front axle utilises braking phases to convert kinetic energy into electric energy. Lithium-ion batteries serve as the energy storage medium. When the driver needs this energy, an electric motor drives the front axle. This makes the 919 Hybrid an all-wheel drive vehicle temporarily. 919 Hybrid A new Porsche team of over 200 employees was formed to develop and implement the Le Mans prototypes at the development centre in Weissach. Friedrich Enzinger, Head of LMP1: “Within two and one half years we built the infrastructure, assembled our team and put this highly complex race car on wheels. We have the greatest respect for the lead our competitors have in racing experience. Our objective in the first year is simple: to finish races and be competitive.” Romain Dumas (France), Neel Jani (Switzerland) and Marc Lieb (Germany) will share driving duties in the Porsche 919 Hybrid with starting number 14. Car number 20 will be driven by Timo Bernhard (Germany), Brendon Hartley (New Zealand) and Mark Webber (Australia). Porsche 911 RSR: Race track icon benefits production cars At Porsche, the pursuit of maximum sporty performance with maximum energy efficiency is condensed into the core brand trait “Intelligent Performance” – it is written in bold letters on both the 919 Hybrid and 911 RSR. This prototype is not the only innovative car on the road. The 911 icon, which has successfully been reinvented in the seventh generation of the car, consistently benefits directly from motorsport developments. The rear-wheel drive 911 RSR, for example, exhibits intelligent lightweight design and refined aerodynamics. These two traits not only result in better lap times but also better fuel efficiency. 911 RSR The 911 RSR, which outputs 470 hp, was first introduced in 2013. Last year, this car finished first and second in its class at the 24 hours of Le Mans, and in January 2014 Porsche celebrated a class victory at the American 24-hour classic in Daytona. The second Porsche factory team, Porsche Team Manthey, will compete with two 911 RSR race cars in the World Endurance Championship series which begins in April. Drivers Jörg Bergmeister (Germany), Marco Holzer (Germany), Frédéric Makowiecki (France) and Patrick Pilet (France) will compete in seven world championship events with each race lasting six hours. Richard Lietz (Austria) and Nick Tandy (Great Britain) will join them for the marathon in Le Mans. Hartmut Kristen, Head of Motorsports, and responsible for Porsche GT Motorsport and all customer sport programmes, explains: Porsche is kicking off 2014 with the most extensive motorsport programme in the company’s history: We have a total of 20 factory drivers now. Along with the factory teams in the WEC, there are two more factory 911 race cars that are being used by the Porsche Cars North America team in the new Tudor United Sports Car Championship series.” Kristen adds: “We have also put the RSR in the hands of customer teams for the first time.” The most prominent international customer is without a doubt the US actor Patrick Dempsey of Team Dempsey Racing Proton. He will be at the starting line in Le Mans for the third time this year.   Source: Porsche
