Audi debuts all-new R18 E-Tron Quattro with novel secondary hybrid system

This is the new Audi R18. It looks like the Bond villain of race cars (it has red running lamps), and if Audi's past is any indication, it'll prove difficult to beat in the LMP1 class of the 2014 World Endurance Championship.
The car's full name is the Audi R18 E-Tron Quattro, just like last year's car. Also like last year's car, the new R18 draws its power from a V6 turbodiesel, which powers its rear wheels, and Audi's E-Tron hybrid system, which runs its front axle. Unlike last year's car, though, this R18 has a secondary hybrid system. Audi has fitted the V6 with an electric turbocharger and figured out how to capture waste heat generated when the engine reaches its boost limit. That power can then be stored and fed back into either the turbo or the front axle's hybrid system under acceleration.
There are a number of changes to the body on the new car, forced in large part by series regulation changes. The car is narrower, particularly at the front, but it's also taller. The front end is set off by a new wing, as part of a new WEC regulation. Audi seems quite pleased about this, citing an improvement in front-end downforce and a reduction in cost. Like Formula One, the WEC contenders now have to contend with a ban on the so-called blown diffuser, which forced exhaust gases over the diffuser, creating downforce. That's necessitated some changes from Audi, although as we have no rear shots of the car, we can't tell you what it looks like.

Audi buys Ballard fuel cell patents for $80 million

While some auto companies (e.g., Toyota and Hyundai) are giving away some hydrogen fuel cell patents, others are paying a pretty penny to gain access to the H2 tech. Audi announced today that it has purchased a suite of fuel-cell patent from Ballard Power Systems. The deal between Volkswagen Group and the Canadian fuel cell pioneer is worth over $80 million US. Unsurprisingly, the value of Ballard's stock shot up about a dollar (to $2.61 as of this writing) on the announcement. VW and Ballard will also extend their development agreement, originally scheduled to end in 2017, to March 2019, and possibly another two years after that. Thus far, the deal – which revolves around the "design and manufacture of next-generation fuel cell stacks" for VW's H2 demonstration program – and Ballard says it is a leader in "critical areas of fuel cell product design – including the membrane electrode assembly (MEA), plate and stack components – along with certain testing and integration work." At the LA Auto Show last fall, VW showed off a Golf SportWagen and a Passat with a hydrogen hybrid HyMotion powertrain as well as a Audi A7 Sportback H-Tron Quattro. Audi buys fuel-cell patents from Ballard Power Systems Development agreement with Ballard extended until 2019 Audi's Head of Development Prof. Hackenberg: "The entire VW Group will use these patents." Ingolstadt/Burnaby, February 11, 2015 – AUDI AG has acquired a package of patents relating to fuel-cell technology from Ballard Power Systems Inc. In addition, the Volkswagen Group has extended its cooperation with the Canadian clean energy company until 2019. The purchase of these patents will provide new impetus for the development of fuel-cell drive systems at Audi, VW and the Volkswagen Group. As explained by Prof. Dr. Ulrich Hackenberg, Member of the Board of Management for Technical Development at AUDI AG and responsible for the steering of the development departments of all brands in the VW Group: "Audi is acquiring these strategically important patents for the entire group and will make them available to all the brands. In this way, we are securing crucial expertise that will provide new impetus for the further development of this technology." Ballard Power Systems Inc. is based in Burnaby, Canada, and is one of the world's leading companies in the technology of proton exchange membrane fuel cells.

2017 Audi A5 First Drive

It might not look it, but behind the 2017 Audi A5's evolutionary styling update there's a new platform and a host of mechanical and technological upgrades that make it the most advanced offering in its class. We got to sample the new A5 on the windy roads outside of Porto, Portugal, which gave us an in-depth look at the car underneath the unremarkable exterior. The A5 may no longer be the haute couture choice in this segment Í­– that title goes to the Mercedes-Benz C-Class Coupe – but there isn't a bad line on the new car, and it's more creased and toned than before. Given the bulging hood and chunky C-pillar, we'd say its gym membership is paying off. This might look more like a mid-cycle update, but what's underneath is new: a scalable architecture known internally at VW Group as MLB Evo, an optional seven-speed dual-clutch gearbox, and the third-generation EA888 2.0-liter, four-cylinder turbocharged gasoline engine. This engine debuted in the A6 and is rated at 252 horsepower and 273 pound-feet of torque. That's a healthy 32 hp and 15 lb-ft more than the 2016 A5's 2.0-liter offered, and it showed on our spirited drive through Portugal's grape-growing region. A handful of A5s will leave the factory with six-speed manuals, but most buyers will find a new seven-speed dual-clutch transmission in place of last year's eight-speed conventional automatic. Audi worked hard to improve initial throttle response to eliminate the clunkiness endemic to torque-converter-free transmissions. In urban slogging, the gearbox does a very convincing impression of a traditional automatic. In sport mode, the transmission livens up and delivers the rapid-fire shifts we expect from this type of gearbox. We did not have the opportunity to sample the stick. Our test car had Audi's Euro-spec version of this engine, which utilizes both direct and port fuel injection. American models will forgo the latter. Brisk acceleration is matched by a subtle growl piped in from under the hood at higher rpm – about the only noise you'll hear. The A5 is astonishingly quiet. In fact, it was that quietness that encouraged us to leave the coupe in the Drive Select's comfort setting for much of our drive. Drive Select tweaks the car's steering, throttle response, and, on cars so equipped, the optional adaptive suspension. Truth be told, Comfort rides a little too plush and Dynamic a little too firm.
