2014 Porsche Panamera arrives with new E-Hybrid, long-wheelbase models

Porsche will officially unveil the refreshed 2014 Panamera at the Shanghai Motor Show later this month, and there's a whole lot in store for the updated model, far beyond the minimal styling tweaks you see here. Sure, there's a new fascia with more prominent LED lighting (including full LED headlamps) and the rump has been tweaked ever so slightly, but the big news for 2014 concerns what's underneath that rakish skin.
First up, Porsche will now offer a Panamera S E-Hybrid model - a plug-in hybrid that builds on the technology first introduced in the Panamera S Hybrid that we tested in 2011. For this new application, a more powerful electric motor and higher-performance battery have been fitted (official specs have not been released just yet), and Porsche says the battery can be recharged in just two and a half hours when the car is plugged in to a 240-volt outlet, and the charging (as well as other vehicle data) can be monitored via a new Porsche Car Connect app available for Android and iOS devices.
The E-Hybrid will have an all-electric driving range of "greater than 20 miles" and will be able to travel at speeds up to 84 miles per hour solely on electric power.

Porsche planning new 911 Speedster as 550 tribute

Some look at the emergence of a new Porsche 911 and see a car. But to Porsche engineers, it might as well be a reset button. Because every time a new 911 comes out, it sets off a tidal wave of new variants to follow, including convertibles, turbos, targas, GT3s... the works.
The next down the pipeline, though, could be one of the most desirable. That, according to German publication Auto Bild, will be a new 911 Speedster. When it arrives early in 2015, the special roadster will reportedly be limited to just 550 examples in tribute to the original 550 Spyder.
It'll reportedly have hidden door handles, a chopped-down windshield and a fabric top to be used only in case of emergency, manually disappearing below a carbon-fiber cowling. All of which makes it sounds as much like a bigger version of the Boxster Spyder as a successor to the last 911 Speedster (pictured above), and that's no bad thing at all.

Jay Leno puts carbon fiber wheels to the test on a Porsche 911 GT3 RS

Jay Leno's Garage usually focuses on looking at cars new and old, speaking to their owners and then Jay taking a drive to see what he thinks. However, Leno throws his usual shtick to the curb this week to do a full product test of the carbon fiber wheels from a company called Carbon Revolution. If you're not interested in hearing about wheels for 18 minutes, don't worry. They get mounted on a Porsche and are tested back-to-back with stock wheels, and Leno takes the 911 for a track test, too.
While carbon-fiber wheels aren't exactly a new idea, Carbon Revolution's goal is to create a lightweight, one-piece product that can be mass produced. The company even claims that it already has a deal with an OEM automaker to offer them on a vehicle in a few years. The key to the technology is that it doesn't need an expensive autoclave to be made.
In the meantime, the company's carbon fiber wheels are available as an aftermarket option for about $15,000 a set, according to the video. They weigh in at about 15.5 pounds each and offer OEM-levels of stiffness, so they could cut some unsprung mass off of a performance car. Watch here as Jay and his mechanic Bernard lap Willow Springs and give their feedback about what they think of this cutting-edge technology.
