Recharge Wrap-up: Porsche buys stake in carbon fiber partsmaker, Formula E runs on solar

The US Department of Energy is providing $35 million in new funding for fuel cell and hydrogen technologies. The money will fund projects to advance technology and speed up adoption of fuel cell applications like light-duty vehicles. Categories for possible projects include deployment of fuel-cell electric hybrid vehicles, mobile refueling and one called "Crosscutting: America's Climate Communities of Excellence." Other possible projects include research and development for hydrogen production, delivery and fuel cell manufacturing. Read more from the DOE. Porsche will buy a 25.1-percent stake in carbon fiber parts manufacturer Capricorn Composite GmbH. Capricorn has provided parts for Porsche's LMP1 racecar and 918 Spyder. The deal will give the automaker better access to the lightweight material going forward, and will "build on joint work over many years in the motor-sports industry and secure the future," according to Porsche. Porsche's parent company Volkswagen owns almost 10 percent of Capricorn's competitor SGL Carbon SE, but an expansion of that ownership could be thwarted by BMW, which controls more of SGL's stock.

Florida Power & Light (FPL) will provide the electricity the cars will be using for the race on March 14, and its Martin Next Generation Solar Energy Center provided the electricity the cars used during the announcement event. "Our partnership with Formula E and the Miami ePrix is another example of our commitment to advancing zero-emissions solar energy and the use of electric vehicles in Florida," says FPL President and CEO Eric Silagy. FPL currently operates two other solar plants, with plans to install 1 million solar panels at three more power plants by the end of next year. Read more at Domestic Fuel.

2015 Porsche Cayenne S Quick Spin

There are sporty SUVs, but until the Macan came along, the Porsche Cayenne was arguably the only pure definition of a 'sports SUV, a la sports car. The second-generation Cayenne is now five years old, but still looks fresh. It's handsome without obvious effort, especially with the optional 21-inch 911 Turbo wheels. The Cayenne S replaces the old, 400-horsepower, 4.8-liter V8 with the brand-new, Porsche-developed 3.6-liter twin-turbo V6. This engine is quickly proliferating through the range – it powers the current Panamera S and the Macan Turbo. That former 4.8-liter started life as a 4.5-liter with 350 horsepower way back in 2002, specifically developed for the Cayenne, and to the end it remained a potent engine. We tried the new forced-induction V6 with 420 hp earlier this year in the Panamera S, and other than a soggy exhaust note it maintained the character of the former V8 sport sedan, with lusty power and hasty delivery. So, how's it do in the Cayenne? Driving Notes The Cayenne S version of the TT V6 gets 420 hp and 406 pound-feet of torque. That means there's 37 more lb-ft than the previous V8, and 22 more lb-ft than in the new Panamera S. Yet the 607-pound difference in curb weight between the Panamera and Cayenne means the V6 has a heavier load to lift here. And it shows – the instant response is dulled. Stomping the right foot gets the eight-speed transmission rappelling through gears to provide a little kick, but real gumption doesn't come until the turbos kick in. We're maybe talking about a second of pause compared to the Panamera, but a noticeable second. Perhaps a small price to pay for slightly better fuel economy, if you really care about such in your 420-hp SUV. Part of why we notice that second is that the Cayenne S is so right-now everywhere else that any perceived hesitation gets extra attention. It offers a specific adjustability that many sports cars don't have, with one button adjusting the three-mode air suspension and a separate Sport button tweaking the steering, throttle, gear changes, and traction control. With Sport keeping all the horses at the ready and the optional Porsche Torque Vectoring holding things steady, you don't need to step up to the GTS trim to get immediate acceleration, crisp steering, flat cornering at very un-SUV-like speeds, and tremendous stopping power from a total of 20 brake pistons. That said, the exhaust note here could also use a shot of Bruce Banner's gamma rays.

The dream of the '90s is alive in Porsche 968 retro review

Only a month after Porsche confirmed that the next-generation Boxster and Cayman will get four-cylinder engines, it is apt that we have a MotorWeek retro review of the 1992 Porsche 968. Porsche hoped the 968 – nee 944 – and its naturally-aspirated, 3.0-liter, four-cylinder would revive sales of its entry-level line, but that didn't happen: going on sale in 1992, 1995 was its last year on the market. This was at a time when a stock 968 coupe cost $39,850, surpassing the out-the-door price of a loaded Chevrolet Corvette. The 968 convertible cost $51,000. That didn't stop MotorWeek's unanimous support of the 968, praising its design, the delivery of its 236 horsepower and 225 pound-feet of torque, and its handling - MotorWeek called it "Pure 90s performance," in spite of some fiddly switchgear and a noisy, firm ride. You can watch the review above. We have a feeling Porsche's four-cylinder fortunes will go much better this time around.
