2017 Porsche Panamera: Technical details of the world's fastest luxury sedan

In anticipation of our upcoming first drive of the new Porsche Panamera, here's an in-depth look at Stuttgart's new sedan. We already know what it looks like, but now we have details on the powertrain, chassis, and electronics. Let's jump right in. Engines, Transmission, Platform The big news is the all-new twin-turbo 4.0-liter V8 in the Panamera Turbo. It adopts a "hot vee" layout with the turbochargers in the engine's valley. This setup allows for a short run from the exhaust manifold for minimal lag, which is further reduced by the twin-scroll turbos. With 18.8 psi of peak boost, the new V8 pumps out 550 horsepower and 567 pound-feet of torque. As we mentioned, that's just 20 hp behind the outgoing Turbo S. And the Panamera Turbo is quick - good for 0 to 60 mph in 3.4 seconds with the Sport Chrono pack. Yes, launch control looks awesome. This is also the first Porsche engine to adopt cylinder deactivation - in four-cylinder mode the engine can run up to 3,500 rpm with as much as 123 horsepower. To shut down four cylinders at a time, the camshaft on each bank slides to engage a dummy lobe on cylinders two, three, five, and eight. When running in V4 mode, the valves stay closed on the shut-down cylinders. Another nod to emissions and efficiency is a catalytic converter mounted close up near the vee, right behind the turbos. All that heat requires airflow, so there's a dedicated duct from the radiator that routes fresh air over the turbos and catalytic converter. There's an all-new twin-turbo 2.9-liter V6 as well, made with the same 90-degree angle as the V8 because it's based on modular architecture. The V6 lacks cylinder deactivation but keeps the hot vee and adds two-stage variable lift on the intake valve. It is not lacking for power, with 440 hp and 405 lb-ft of torque. Both engines (and the European-market twin-turbo 4.0-liter V8 diesel) mate up to a new eight-speed dual-clutch automatic made by ZF. The new design is 5.6 inches shorter than the seven-speed it replaces and allows for an upcoming hybrid powertrain to be integrated without adding any extra length. The top three gears are overdrive ratios, with the top speed from both engines coming in sixth. Along with leading the development of the new V8, the Panamera is also the first car on the new MSB platform. That's Modularer Standardantriebs-Baukasten for you AP German students; a near-literal translation is modular standard drive.

Nick Murray's problematic Porsche 911 shows the power of a viral video

When Nick Murray took delivery of his 2013 Porsche 911 Carrera S in June 2013, he had saved for it for the past five years. He didn't just pluck a random 911 off a dealer lot. He specially ordered his car with thousands of dollars in extras tailored just to him, and he captured all of the options on his YouTube channel. The love affair didn't last long. Eventually the channel became a place for Nick to air his growing list of grievances about his deteriorating 911. Eventually, his mix of righteous indignation and sarcasm went viral.
By late December, he had already had four warranty repairs done on the car. Things got much worse in March. The computers began resetting whenever Nick drove over large bumps. There was also an acrid, electrical smell that occasionally permeated the cabin. Murray filed for Lemon Law protection. Porsche Cars North America contacted him for the first time to fix the problem, but it didn't help.
Things culminated in April when Murray put up a new video that showed more troubles. He began arbitration with Porsche and asked for either his full purchase price back or an exact replacement. The company countered with a portion of what the car was worth, based on its mileage. Murray refused and turned to his YouTube watchers for help. He asked them to spread the word, and the video went viral with over 800,000 views as of this writing. Supporters posted it multiple times on Porsche's Facebook and Twitter sites.

Singer 911 gorgeousness explored and experienced by Chris Harris

Few things get us as cranked up as a Porsche 911. Generation after generation, this rear-engined oddity has exhilarated our senses, and the new 991 is the most capable iteration yet. Even so, there's a lot to be said for the older models, from their lighter weights and more modest dimensions to their air-cooled thrums.
That elemental vintage Porsche appeal hasn't been lost on Los Angeles-based Singer Vehicle Design, which has endeavored to take the best bits from every generation of 911 and combine them into one impossibly sexy rear-engined machine. Based on a 964 donor car, we knew that a lot of work would need to go into everything from the structure to the bodywork to realize the Singer's cohesive aesthetic and dynamic vision, but we didn't know just how much until we watched this Drive video featuring Chris Harris. The auto journo gets time with the 350-horsepower, Cosworth-motivated coupe on both mountain passes and at the track, but what could be the most interesting thing about the 27-minute-long video is his in-depth plant tour.
