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 Panamera Turbo S vs Ariel Atom Supercharged in unlikely drag battle

David versus Goliath battles are always an enticing proposition, because they offer the chance to watch scrappy underdogs take on their bigger rivals. Evo has set up just such a battle with its latest drag race between the minimalist Ariel Atom 3.5 Supercharged (Ariel Atom 3 pictured below) and the plush Porsche Panamera Turbo S.
The two cars couldn't be more different. The Atom personifies Lotus founder Colin Chapman's well-known axiom: "Simplify, then add lightness." Most of the car doesn't even have a body; it's just an exposed frame with a 310 horsepower supercharged Honda four-cylinder mounted behind the driver. On the other side, there's the Panamera Turbo S. In the latest version, it packs 570 hp and 553 pound-feet from its 4.8-liter twin-turbo V8 and it features all-wheel drive. Of course, all of that comes with a significant weight penalty.
Off the line, the differences are even more apparent. The Atom doesn't have any of the Porsche's technological wizardry, so launching it challenges the driver to build the revs and let out the clutch just right. The car screams like a banshee as it goes, though. The Porsche is the exact opposite. Its launch control system lets the driver hold down the brake, get on the throttle and accelerate away in just the right way.

The Bearable Lightness Of Being
Start with a standard Porsche 911 Carrera and its 350-horsepower, 3.6-liter flat six-cylinder engine. Bore a crepe-thin slice of aluminum from each cylinder to get to 3.8 liters, add a wider track out back and two extra exhaust pipes and voila, you can append an S to the Carrera's name. Hang two sets of wet, multi-disc clutches along its spine and you can make that a 4, or a 4S. Bolt on two forced-induction compressors and piping, add two fender vents and comically wide rear tires and you've redeemed your ticket to a Turbo. Increase the boost pressure and swell the corral to 560 horses and you have the Turbo S, which is the Virginia Slims of the 911 line-up because it's come a long way, baby.
Or you can go in a different direction. At that second stop, grab the 3.8-liter and cart it over to the engineers at Porsche's development center in Weissach, Germany. If racing were meat, they would be among the alpha carnivores. The baseboards in their homes are probably painted with miniature billboards for motor oil and vintage cigarettes along the straights, red-and-white stripes around every corner.
