Porsche 919 Hybrid revives Porsche's factory Le Mans efforts

After months of teasing with camouflaged testers, Porsche has finally unveiled its prototype entry for the 2014 World Endurance Championship, the 919 Hybrid. Porsche, you may recall, hasn't had campaigned a factory team at Le Mans in years, so the 919 is nothing less than their recommitment to endurance racing.
Combining a 2.0-liter V4 (yes, a V4) that revs to 9,000 rpm, the 919 produces around 500 horsepower with a pair of energy recovery systems. The first system recovers the heat energy from exhaust gasses as they pass through an electrical generator, while the second system is a bit more familiar. Using a setup similar to what is found on the production 918 Spyder, a generator on the front axle recovers kinetic energy from the brakes, which is subsequently stored in a battery system. That power can then be sent to the front wheels at the driver's command, effectively turning the 919 into an all-wheel-drive racecar.
Despite these various forms of motivation, Porsche doesn't claim to be seeking outright power supremacy, with Chairman Matthias Müller saying, "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."

UPDATE: Porsche could raise its stake in Rimac, and Rimac weighs in

CLARIFICATION: An earlier version of this Reuters story said Porsche could raise its stake in Rimac to nearly 50%, but Rimac reached out to Autoblog to say that's not so. Here is a statement from Mate Rimac: "We have a very strong partnership with Porsche that is key for Rimac Automobili. Porsche is a shareholder in Rimac since 2018 with 15.5% ownership currently, accumulated over several rounds of investment. While it is true that we are discussing further expansion of this collaboration that will lead to increase of Porsche's stake in Rimac Automobili, some media have mistakenly reported that Porsche would take over 50% or nearly 50% of the company.   We are very happy that the partnership with Porsche will strengthen even further, but it is in the interest of both Rimac and Porsche that Rimac is a fully independent company. We are working with many car companies that are not our shareholders and there is a clear separation between shareholding and projects. It is very important to us that our industry customers have the peace of mind that Rimac is independent and that there is an "Information Firewall" between projects and shareholders (not only Porsche, but also Hyundai and others) - and this will not change. Confidentiality is very valued in the industry and one of the basics for collaboration between companies. Our shareholders are happy with such an arrangement and expect the same level of professional behaviour and confidentiality for their projects and customer projects.   So, the point is: Porsche's stake will increase but nowhere near to 50% and Rimac will remain independent with many industry customers that are not our shareholders/investors." The original story, with the 50% reference removed, appears below.   FRANKFURT — Volkswagen unit Porsche is participating in a financing round of Rimac Automobili that will see the electric supercar maker raise 130 million-150 million euros ($157 million-$181 million), its owner Mate Rimac told weekly Automobilwoche. The fundraising should be completed in two to three months and another round is planned at the end of the year, Rimac told the trade journal. Porsche owns a 15.5% stake in Rimac Automobili and could raise its stake in a deal that would also include the transfer of Volkswagen's supercar brand Bugatti to Rimac, Automobilwoche said. Volkswagen and Rimac were not immediately available for comment on Sunday.

New info on how VW, Porsche, Audi V6 TDI engine cheat works

The German newspaper Bild am Sonntag is reporting that US investigators have found three pieces of software that work in concert to turn off the emissions control equipment in certain diesel models after a set period of time. The engine in question, the 3.0-liter TDI turbodiesel, was found in certain Volkswagen Touareg, Audi Q7, and Porsche Cayenne models – the sale of which was suspended in the US late last year. Since most emissions compliance testing takes around 20 minutes, the software in the three VW Group models shuts off the emissions control equipment after 22 minutes, a straightforward end run around the testing. Remember that the 3.0-liter TDI engines aren't included in the big buyback and recall program announced for the smaller 2.0-liter, four-cylinder TDI engines. The 3.0-liter engines will likely get their own program, but we don't know when to expect it or exactly what it will look like. Last month, California rejected a proposed fix for the larger TDI engines, and VW went back to the drawing board. Since the company is unlikely to create two fixes, one for California and one for the rest of the nation, the company can't really proceed until they figure out a solution California will accept. The EPA hasn't officially commented on the report, and we don't know how Bild am Sonntag came across the information, but we'll be closely watching what emerges after this report. Related Video:
