Porsche reportedly working on new turbocharged flat-four boxer engine?

These days, we've seen just about every automaker dropping cylinders in an effort to appease tightening fuel economy and emission standards - and Porsche is no exception. Nearly three years after introducing an all-new V6 powerplant under the front hood of its Panamera sedan (launched with a range of V8 engines) comes word that Porsche is working on an all-new turbocharged flat-four boxer to replace the flat-six engines mid-mounted in its Cayman and Boxster models.
Specifics have yet to be learned, but reports say the engine is a derivative of the current 3.8-liter six (shown above) found under the rear decklid of the Carrera S, yet with two fewer cylinders. Fitted with a turbocharger, direct-injection and the automaker's VarioCam Plus, the new all-aluminum 2.5-liter flat-four will likely develop upwards of 350 horsepower and 360 pound-feet of torque. Redline should be about 7,500 rpm. Initial indications say that Porsche will only offer the new engine with its seven-speed PDK dual-clutch automatic, tuned to take advantage of the low-end torque, but a traditional six-speed manual gearbox has not been ruled out. Despite the loss of two cylinders, enthusiasts will likely embrace the new engine as it promises to be lighter, more fuel efficient and more powerful than the 2.7-liter and 3.4-liter sixes in the Cayman/Boxster today.
Even though Porsche has been using Volkswagen Group engines for years (e.g., Cayenne V6, Cayenne Diesel and upcoming Macan), all indications are that the new flat-four will not be shared. Instead, it will be kept in-house for the automaker's sports cars and possible future fitment in an entry-level 911.

Porsche considering X6-style Cayenne coupe

It was practically unthinkable when Porsche introduced the Cayenne in 2002. An SUV... from Porsche? Purists balked, but customers flocked, and the Cayenne propelled the its holding company into such profitability that it practically took over the entire Volkswagen Group. It's now been twelve years since the original Cayenne arrived as the first production Porsche with more than two doors, and Zuffenhausen has since followed up with the Panamera, the Macan and the second-generation Cayenne. But it isn't about to stop there.
The latest intel coming in from overseas suggests that Porsche is in the advanced stages of designing a slant-back, five-door Cayenne coupe to take on the likes of the BMW X6 and upcoming Mercedes-Benz MLC. Though the business case (however solid BMW may have already demonstrated it to be) is still being considered, if approved it would join the upcoming third-generation Cayenne on the production line in Leipzig as early as 2018 - a year after the new Cayenne itself is expected to arrive.
The Cayenne coupe would share much with the more conventional MkIII Cayenne (and for that matter the next Audi Q7 and VW Touareg as well as the Lamborghini Urus and Bentley Falcon) but differentiate itself with a more stylish (if less practical) roofline and an altogether sportier attitude. Autocar reports that the design calls for tauter sheetmetal and sportier cabin inspired by the 918 Spyder. Pricing would be positioned a good 15-20 percent higher than the regular Cayenne, and the "coupe" version would likely be offered with most, if not all of the engines available in the conventional version - including gasoline, diesel, turbo and possibly even hybrid options ranging all the way up to the 550-horsepower Turbo S.

The pre-race and first in-race report from Le Mans

The 2013, 90th anniversary edition of the 24 Hours of Le Mans has begun, tragedy marking the opening laps with the death of Allan Simonsen. We're at the track now as a guest of Audi and plan to stay through the evening, and even we haven't been able to find out what caused the accident - the only video is from just after the incident, and beyond the statement from ACO there's been no more news. The Aston Martin in the LM GTE Am class and its all-Danish drivers had taken pole in its class and was one of the favorites to win.
The pre-race report will come first, and even thought we can't spoil the race because we're only five hours into it at the time of writing, we'll put all of the news at the end in case you don't even want the updates.
