Porsche 5 Series fighter may be electric

We know that Porsche is developing a seventh model range for its lineup thanks to the March announcement from company boss Matthias Muller. The actual identity of this future vehicle remains a mystery, though. Autocar is coming down firmly on the side of the smaller Panamera, codenamed the Pajun, and speculates the new entry might be available in battery electric and hydrogen fuel cell versions based on recent patent filings. Porsche is famous for sticking with the rear-engine layout on the 911 for decades, even as the company moves the powertrain forward in other models. According to Autocar, the EV version of the Pajun might mark a return to these roots. The German brand is reportedly preparing a modified version of Volkswagen Group's MSB platform for the new vehicle. Called eMSB, the setup puts the batteries and electric motors at the back, and each rear wheel would receive power separately to allow for torque vectoring. The system is estimated to generate 420 horsepower, which is on par with the all-wheel-drive Tesla Model S 85D. The fuel cell Pajun would join the lineup later. The Pajun is rumored to take on the likes of the BMW 5 Series and Mercedes-Benz E-Class, but any luxury EV of that size must count the Tesla Model S as a competitor, too. According to Autocar, the styling takes cues from the Panamera Sport Turismo concept (pictured above) and could launch around 2018. Rumors of Porsche's Tesla-fighter were swirling for months before Muller's announcement, and talk of the Pajun has gone on even longer. Previous reports have suggested the possibility of a 300-mile range and an all-wheel-drive layout with 600 hp. While the actual design has remained ambiguous beyond the potential link to the Panamera, the model was possibly spied last year at the Porsche Design Tower in Florida.

NHTSA closes probe into 2011 Porsche 911 coolant leaks

The National Highway Traffic Safety Administration has announced that it will end its investigation into rapid coolant loss in 24,635 Porsche 911s built between 2001 and 2011. The models affected included the standard 911, GT2, GT3 and Turbo, as well as their variants (GT2 RS, GT3 RS and Turbo S).
NHTSA was investigating for "rapid coolant loss caused by coolant pipe-fitting failure, allegedly resulting in vehicle disablement and/or loss of vehicle control due to reduced traction for the affected vehicle or following traffic," according to the regulators website. "Most of the leak complaints did not appear to involve complete separation of the fittings and many were detected when the vehicle was parked," said NHTSA's statement.
There were 63 complaints and 336 warranty claims, although the investigation was initiated after ten complaints from customers. There have been no reports of crashes or injuries attributed to rapid coolant loss.

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.
