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.

Mysterious Porsche 911 Cabriolet spied, could be GTS

While Porsche's designers can jokingly be accused of being some of the laziest in the industry due to the incremental changes to the 911's iconic design, no such charge can be leveled against the engineers and product planning folks. That's because it seems like each week arrives with news of a new variation of the marque's iconic rear-engined sports car. So, for this week, we've brought you images of what we think is the new 911 GTS Cabriolet, undergoing testing in a thawing winter wonderland.
Now, what is it that gives this 911 away, compared to standard convertible? Well, the big thing is the new offset, center-mounted exhausts. Borrowing a page from the last Volkswagen R32, these exhaust tips are unlike anything we've seen from Porsche. Only the GT3 wears center pipes, and unlike these spy photos, the twin pipes on the track-minded 911 are stacked neatly alongside each other. The other change spotted by our spies is the set of active-aerodynamic flaps in the front bumper, which can automatically channel air toward the brakes for increased cooling, or close off to reduce drag, as needed.
Those exhausts are a pretty big design detail, and so far as we can tell is the only differentiator between the other 911s in this car's posse. Our spies speculate that this could be a 911 Speedster, but point out that both the canvas roof and windshield remain unchanged - the rumored Speedster model would almost certainly feature a different roof assembly along with a steeply raked windshield.

Stock Miata beats bunch of high-powered cars in wet 1/4-mile drag race

When is a stock, 167-horsepower Mazda MX-5 Miata quicker than a Chevrolet Corvette, Ford Mustang, Lamborghini Gallardo, Lotus Elise and a Porsche 911? When it's raining. Sort of.
Mazda Canada arranged a unique drag race to show off the fact that the Miata's optional power retractable folding hardtop can go from top-down to top-up in just 12 seconds flat. In this video, all six cars line up for a drag race, and it starts to rain (well, sort of - but you'll have to watch the video all the way to the end to see what we mean). The green flag is waved, and the timer starts as soon as the convertibles begin to put their tops up. But because the Miata's roof mechanism gets the car's roof back up a full 5.1 seconds quicker than the second-place car, the Mazda gets a serious advantage off the line for the actual drag race.
It's a fun video. And while we've spoiled the results (come on, the video was uploaded by Mazda, you knew the Miata was going to win), be sure to see how it all unfolds, below.
