Porsche engine wizard Wolfgang Hatz resigns

Wolfganag Hatz has resigned from his position as Member of the Porsche Executive Board with responsibility for Research and Development. He has held that title since 2011. Hatz's storied career came to an abrupt end in September when he was suspended pending investigation into the Volkswagen diesel scandal. Before the Porsche job, Hatz was the head of engine and powertrain development for the Volkswagen Group. It has been alleged that he is at the center of the investigation into the company cheating on emissions testing, but so far there has been no direct link made to him, according to Porsche's announcement today. Hatz has worked at a variety of European automakers, including Audi, BMW, Opel, and Fiat. He is considered the father of the BMW S14 engine, which powered the E30 M3, and also developed the Porsche 911 Carrera RS 3.8. He was also very involved in Porsche's motorsports efforts, including the recent return to the prototype class and a short-lived F1 V12 engine project. Ulrich Hackenberg, most recently VW's lead engineer and a board member at Audi, was also suspended at the same time as Hatz and resigned shortly thereafter. It's not clear why Hatz waited so long to do the same, but Porsche claims his resignation was voluntary. Michael Steiner has been named Hatz's replacement as head of Porsche R&D. Steiner has been with Porsche since 2002 and seems like a forward-thinking sort, having headed the innovation and concepts division, lead Panamera development, and, most recently, been in charge of complete vehicle engineering. Prior to his time at Porsche, Steiner held positions at Daimler. The change in leadership is effective immediately. Related Video:

2015 VW Beetle GRC packs 553 rallycrossing horsepower

In case you couldn't tell from all the wings and vents, this is not your average Volkswagen Beetle. It's the rally machine Tanner Foust and Scott Speed will be driving in the Global Rallycross Championship this year. Don't let the retro form fool you – it is an absolute beast. Last year's Beetle GRC packed a 1.6-liter turbo four good for an astonishing 544 horsepower and 387 pound-feet of torque, but the new one does one better: it now features a 2.0-liter turbo four good for 553 hp and 465 lb-ft. That's right – in a Beetle. It's also got ZF dampers, 9.5 inches of suspension travel, 14-inch front brake discs with four-piston calipers packed into 17-inch wheels and, of course, all-wheel drive. The result? 0-60 in – wait for it – two seconds flat (or thereabouts). It's geared low so it'll only top out at around 125 miles per hour, but that's all it needs for the short tracks on which it's designed to compete. Foust and Speed will be driving this beast for Andretti Autosport in the 2015 championship that kicks off at the end of May in Ft. Lauderdale. Both have quite the act to follow as Foust won back-to-back titles in 2011 and 2012, and former F1 driver Speed won three rounds last season to finish third in the standings.

In 2015, the team will be on the attack with two Beetle GRC race cars, which debuted in the final races of 2014. This rallycross car is the ultimate expression of the third-generation Beetle. Designed and engineered from the outset as a GRC car, it features a sequential six-speed transmission, with a fixed-ratio all-wheel-drive system that features multiplate limited-slip differentials at the front and rear. For the 2015 season, the team has chosen to change the engine specification from the car that ran in selected rounds of the 2014 series. In place of that car's 1.6-liter turbocharged and intercooled TSI® four-cylinder engine, there is now a 2.0-liter TSI engine that produces 553 horsepower and 465 pound-feet of torque, compared to 544 hp and 387 lb-ft for the 2014 car.

More automakers working to turn your smartphone into a shareable digital car key

The smartphone killed the phone book, audio player, the pocket digital camera, handheld GPS devices and voice recorders. Now that addictive, transistor-filled candy bar is coming for your car keys. The Car Connectivity Consortium (CCC) announced that it's unveiled Digital Key Release 1.0 Specification for its member companies, which is the first step in standardizing protocols. As of now, the potential is there for drivers to download a digital key that can lock and unlock the car, start it, and transfer the key to another operator in order to share the car. The CCC's aim is to save development costs, stave off a glut of similar-yet-competing technologies, and create keys that reflect the expanded use cases for cars, i.e., car-sharing services and to-your-car delivery. Next year's Release 2.0 Specification will standardize an authentication protocol between the phone and the vehicle — how a digital key is generated on a secure server and transmitted to the car and the device — and "promise more interoperability between cars and mobile devices." The CCC says that "NFC distance bounding and a direct link to the secure element of the device" will assure security. We take that to mean the phone will need to be in direct contact with the vehicle, at least to open the door. Carmakers and suppliers have been working on digital keys for years now, and the ecosystem for individual owners to open individual cars is growing. Audi showed off its Mobile Key at the 2015 Consumer Electronics Show, and now calls it Audi Connect Key, but we haven't seen much of it in the field. That same year, Volvo said it expected to sell cars with digital keys only by 2017, which clearly didn't happen. Last year, the head of sales at BMW asked, "Honestly, how many people really need [keys]? They never take it out of their pocket, so why do I need to carry it around?" Even though a digital key offers an owner more convenience and long-distance control over their vehicle, car sharing is the target — and that can even include traditional rental cars. In 2013, Continental began testing a digital key in France, aimed at integrating and simplifying the electric-car-sharing business; everything from finding a free vehicle to driving it and charging it could be done on a phone. A key could be programmed with the driver's information, so that any car the driver gets in will be automatically updated with that driver's preferences, say for audio or seating position.
