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.

Meet the new Porsche 718 Boxster and Boxster S

The rumors were mostly true. Porsche had already confirmed that the Boxster and Caymans would receive a "718" appended to their badges, in honor of their famous mid-engined racecar of the 1950s and '60s, but the mechanical details were left up in the air. We were almost certain both would be powered by turbocharged flat-fours of a couple of displacements and outputs, and now we can confirm that this is the case. Porsche has revealed the official specs for the 718 Boxster, which will go on sale in Europe this April. The biggest news concerns the flat-fours. The regular 718 Boxster will get a 2.0-liter, turbocharged flat-four producing 300 hp. The 718 Boxster S will get an extra half-liter of displacement and a variable-geometry turbocharger to produce a total of 350 hp. This represents a 35 hp gain over the current Boxster and Boxster S, respectively. Porsche also claims the turbo fours improve fuel economy by around 13 percent. By the NEDC European test cycle, the 2.0-liter gets roughly 34 mpg and the 2.5 gets 32 mpg, although rest assured that EPA test results will yield different numbers than the optimistic European test. Torque gains with the new boxer fours are significant. The 2.0-liter gains 74 lb-ft of torque for a total of 280 lb-ft from 1,950 to 4,500 RPM. The 2.5 gains less, 43 lb-ft, for a total of 309 lb-ft over the same rev range. The extra torque and wide torque band make the 718 Boxster quicker to 60 mph, at least when equipped with the PDK gearbox and the Sport Chrono Package. The 2.0-liter car does the deed in 4.5 seconds, a 0.7-second improvement, and the 2.5-liter car is claimed to hit 60 mph in 4.0 seconds, a 0.5-second improvement. 2016 Porsche 718 Boxster View 11 Photos Inside, a new dash houses the latest Porsche Communication Management infotainment system with a touchscreen, included on all 718 Boxsters as standard – although nav is an optional extra. The buttonless, capacitive-touch center stack we just spied on the next Panamera does not make it inside the 718 Boxster, which makes do with a very similar button layout to the current car. Both cars will come with a six-speed manual as standard, which is great news, and a PDK will be optional for both. Porsche also claims to have made the electrically-assisted steering more direct, and retuned the suspension. An optional PASM package lowers the car by 0.4 inches while providing the benefits of active dampers. From a styling standpoint, this is an evolution of the current theme.

Porsche to only build next Panamera in Leipzig?

Manufacture of the next-generation Porsche Panamera could be moving, if a report from Reuters is true. The current-generation Panamera range has its bodies welded together and painted at a Volkswagen facility in Hanover before being shipped to Leipzig where final assembly takes place.
According to Reuters, Porsche is looking to cut VW out of the equation and focus production of the Panamera in Leipzig. While this could cost 800 of the 14,300 workers at Hanover their jobs, it's not entirely clear what Porsche stands to gain by the move. It recently invested 50- million euros (about $680 million at today's rates) on a paint and body shop for its Leipzig factory, ostensibly so the facility could have Macan production underway by that car's spring 2014 on-sale date. If the facility was also designed with next-generation Panamera production in mind, then Porsche's decision to put all of its eggs in one basket could make a lot of sense. It currently ships the semi-completed Panameras from Hanover to Leipzig, a distance of around 160 miles by road, and presumably it's a costly and time-consuming process.
The Leipzig factory produced 27,000 Panameras last year, although it's unclear just what its production capacity really is. Besides the Panamera and the upcoming Macan, the factory also builds the Porsche Cayenne.
