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 hybrids come up short at Le Mans

Two cars, one finish, zero victories. That's a brief synopsis of Porsche's hybrid-vehicle performance in the 24 Hours of Le Mans race in France. There's always next year. Porsche entered two 919 Hybrid vehicles in the race. The No. 14 car essentially limped to the finish line after encountering drivetrain problems. The other Porsche hybrid, No. 20, was driven by Germany's Timo Bernhard, New Zealand's Brendon Hartley and Australia's Mark Webber. That car ran for more than 22 hours before its own powertrain issues did that racing team in for good. Both vehicles ran towards the front of the pack at times during the race, and the No. 20 car actually led the race after about 20 hours. Still, both teams said they were disappointed in the results. Porsche sister company Audi came up big for the 13th time in the race's long and storied history. One Audi R18 E-Tron Quattro won the race, while another finished second. The Toyota that had pole-position and was winning much of the race shut down after 15 hours of racing because of electrical issues and Nissan had trouble with is ZEOD RC.

After a strong performance by both Porsche 919 Hybrids, the Porsche Team was left empty-handed after a dramatic final stage of the race. Following more than 22 hours, car No. 20 driven by Timo Bernhard (Germany), Brendon Hartley (New Zealand) and Mark Webber (Australia) suffered a powertrain problem at the world's most famous endurance race, the 24 Hours of Le Mans. Earlier in the race the LMP1 class car was leading overall for a significant period of time. The second innovative and highly complex prototype – in the hands of Romain Dumas (France), Neel Jani (Switzerland) and Marc Lieb (Germany) – likewise proved to be very competitive, but was hampered by a drivetrain problem. However, their No. 14 car crossed the finish line under its own power. After a thrilling start to the race with changing weather conditions, numerous accidents and a relatively calm night, Bernhard took the overall lead in the No. 20. The longtime Porsche factory driver returned to the top spot after 20 of the 24 hours. At 12:36 (CET) on Sunday, he handed the leading car over to Webber. Less than 20 minutes later the Australian was forced to slow down and drove solely on electric power back to pit lane.

Modded budget Mazda Miata takes on new Porsche Boxster in more challenges

Earlier this month, our friends across the pond at Auto Express released the first in a two-video series that would see them try and build up a second-generation Mazda MX-5 Miata that could best a standard Porsche Boxster around the track. While that first video detailed the mods to the MX-5 - a supercharger, some suspension upgrades and a new set of super-sticky rubber being chief among them - and set baseline lap times for the stock car, today, we have the results of the 5,000-pound ($8,200) upgrade job.
Of course, we aren't going to spoil those for you. You'll need to watch the full video, which recaps the upgrades before digging into a comparison of both straight-line-speed differences between the 2.7-liter Porsche Boxster and blown Miata, as well as their behavior and lap times on the track.
