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.

Overnight action from the 24 Hours of Le Mans

We won't go into a recap here, but there are still leading positions being fought for in all classes - it's so close that leads are changing when a car goes into the pits. We'll let the recap wait until the end of the race, so for now enjoy some shots from last night's action at the 24 Hours of Le Mans.

2014 Porsche Panamera Diesel is something to torque about

Porsche has been in the business of slaying sacred cows for the better part of a decade, from venturing into the SUV space with the Cayenne to the four-door realm with its Panamera hatchback. And if those vehicles didn't leave brand purists apoplectic enough, Porsche has been adding diesel and hybrid power to its portfolio, thought to this point, neither alt-fuel motivator has made its way into the brand's sports car lineup.
Today's Frankfurt Motor Show effectively marks the second-generation of diesel power in the Panamera, and this updated 3.0-liter V6 features 300 horsepower (50 ponies more than last year) and a whopping 479 pound-feet of torque, available from 2,500 rpm. That power is achieved with a new higher-pressure, water-cooled turbo and redesigned engine internals that include a new crankshaft and pistons. The newfound increase is said to raise top speed to 161 miles per hour from 152, and drop the car's 0-62 mph time from 6.8 seconds down to 6.0. It also figures to be a better handler, with a new torque-vectoring rear differential borrowed from its gas-powered brethren and a reworked transmission for crisper shifts. The suspension has also been retuned, along with the updated 2014 visuals first revealed at April's Shanghai Motor Show.
No word yet on the North American sales prospects of this diesel Panamera, but we imagine that depends in part on how well the Cayenne diesel is selling.
