Porsche would have entered F1 if Audi had blocked its Le Mans program

Go back a few years and you may have heard rumors of Porsche heading into Formula One. That never came to pass - or at least, it hasn't yet - but that doesn't mean that it wasn't close to happening. That's how committed to returning to top-level motorsport competition Porsche has become recently.
Autosport reports that just as Porsche was merging fully into the Volkswagen Group, Zuffenhausen was weighing its options for a factory racing program. Le Mans was its favorite, which makes sense, as it remains far and away the most successful constructor in the history of the famous endurance race. But the strategists at Porsche were worried that its new corporate overlords at Volkswagen wouldn't support two LMP1 programs and would favor Audi, which has positively dominated the modern era of endurance racing, coming second only to Porsche in the number of Le Mans victories it has scored to date.
Porsche's Plan B was reportedly to head into Formula One, although it isn't clear if the German automaker was intent on starting its own team, buying an existing one or merely providing engines to other teams. Porsche fielded its own cars in F1 in the late 1950s and early 60s, and returned as an engine supplier with TAG to power McLaren in the 1980s, powering Niki Lauda and Alain Prost to the World Championship in 1984 and 1985.

2015 Audi A8 rises to meet the challenge [w/video]

It's turnover time in the extra large premium sedan segment. With Mercedes having stuffed HAL 9000 in its new S-Class, other luxury marques are quickly updating their own super sleds to keep up with this persistent march of technology. While far from a full redesign, the Audi A8 has changed enough for 2015 in terms of styling, powertrains and new technology to keep it in the conversation.
For starters, the A8's exterior design has been redone, with the most noticeable changes happening up front. The trademark 'gaping maw' grille is a little less gaping, while the headlights now feature a straight lower edge of LEDs, excising the old model's droopy-eyed look. Speaking of headlights, Audi now offers optional Matrix LEDs, the latest in headlight tech, with 25 individual elements per side that can be turned on or off and dimmed as the situation demands. The rear of the A8 has also been resculpted and looks very much inspired by the derrière of the A7, with a single chrome strip connecting the new LED taillights.
The A8's full suite of powertrains has also been upgraded, with the supercharged 3.0-liter V6 now producing 310 horsepower (up 20 according to Audi, though down 23 compared to the US-spec 2013 model). The twin-turbo 4.0-liter V8 is now rated at 435 hp, a solid 20-horse increase that lowers the car's 0-62 time to just 4.5 seconds. That's within spitting distance of the 520-hp S8's time of 4.1 seconds. That aforementioned super sport sedan's engine remains unchanged, as does the 6.3-liter 12-cylinder powerplant in the A8 L W12, but Audi's two diesel engines have both improved, with the 3.0-liter V6 producing an extra eight horsepower (256 total) and the 4.2-liter V8 gaining an extra 34 hp (385 hp) to go along with its more-than-adequate, though unchanged, 626.93 foot-pounds of torque.

Audi rumored to ditch Le Mans, DTM for F1

If you've been scratching your head wondering how - between Audi and Porsche - the Volkswagen Group could possibly support two rival top-tier LMP1 programs at Le Mans and the FIA World Endurance Championship, but stay out of Formula One entirely, you're not alone. In fact, Porsche was said to have been eying an F1 entry if Audi had internally blocked aspirations to return to Le Mans. But according to the latest rumors, it's Audi that's now preparing to shift away from endurance racing and onto the grand prix circuit.
Word has it that, following internal pressures from within the VW Group, Audi is finally gearing up for a full assault on F1. It's said to be developing a new six-cylinder turbo hybrid power unit - potentially at its new racing headquarters in Neuburg - and, in an expanded partnership with Red Bull, either take Renault's and Infiniti's places with the Red Bull Racing team or take over the Toro Rosso team entirely.
Although Ingolstadt has not campaigned in grand prix racing since the pre-war days of the Silver Arrows, it was said to have been the impetus for the FIA's push a couple of years ago for new four-cylinder engine regulations until Audi bailed on the idea altogether and F1 went for six-cylinder engines instead.
