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:

Lexus tops JD Power Vehicle Dependability Study again, Buick bests Toyota

It shouldn't surprise anyone, but Lexus has once again taken the top spot in JD Power's Vehicle Dependability Study. That'd be the Japanese luxury brand's fourth straight year at the top of table. The big news, though, is the rise of Buick. General Motor's near-premium brand beat out Toyota to take second place, with 110 problems per 100 vehicles compared to Toyota's 111 problems. Lexus owners only reported 89 problems per 100 vehicles. Besides Buick's three-position jump, Scion enjoyed a major improvement, jumping 13 positions from 2014. Ram and Mitsubishi made big gains, as well, moving up 11 and 10 positions, respectively. In terms of individual segments, GM and Toyota both excelled, taking home seven segment awards each. The study wasn't good news for all involved, though. A number of popular automakers finished below the industry average of 147 problems per 100 vehicles, including Subaru, (157PP100), Volkswagen (165PP100), Ford/Hyundai (188PP100 each) and Mini (193PP100). The biggest losers (by a tremendous margin, we might add) were Land Rover and Fiat, recording 258 and 273 problems per 100 vehicles. The next closest brand was Jeep, with 197PP100. While the Vehicle Dependability Study uses the same measurement system as the Initial Quality Survey, the two metrics analyze very different things. The VDS looks at problems experienced by original owners of model year 2012 vehicles over the past 12 months, while the oft-quoted IQS focuses on problems in the first 90 days of new-vehicle ownership. Like the IQS, though, the VDS has a rather broad definition of what a problem is. Because of that, a low score from JD Power is no guarantee of extreme unreliability, so much as just poor design. In this most recent study, the two most reported problems focused on Bluetooth connectivity and the voice-command systems. The former leaves plenty of room for user error due to poor design (particularly true of the Bluetooth systems on the low-scoring Fords, Volkswagens and Subarus), while the second is something JD Power has already confirmed as being universally terrible. That makes means that while these studies are important, they shouldn't be taken as gospel when it comes to automotive reliability.

ACEEE strips away VW's green car scores

The American Council for an Energy-Efficient Economy (ACEEE) is confirming that the Volkswagen diesel-emissions scandal has put a black mark on its green ratings. As a result, the group is pulling VW diesel vehicles off of its "Green Scores" list because it was recently revealed that VW diesels might be emitting as much as 40 times the nitrogen oxide (NOx) emissions during normal driving as the official test results show. The ACEEE added that other German makers of diesel vehicles' "Green Scores" are safe, for now. Diesels from VW and the company's Audi division didn't exacatly top the ACEEE's list of greenest vehicles for 2015. That honor went to electric vehicles like the Smart ForTwo ED, Chevrolet Spark EV and Fiat 500E. The Toyota Prius C hybrid snuck in at number 4, while the Nissan Leaf battery-electric took the fifth spot. That said, the VW diesels did perform pretty well, according to the group. "These scores are no longer reasonable estimations of the environmental impact of the Volkswagen diesels. Volkswagen's diesel cars have performed well on ACEEE's annual rankings since 2009, hovering just below our list of the top twelve "Greenest" vehicles with Green Scores in the high 40s," wrote Shruti Vaidyanathan, senior transportation researcher at the ACEEE. "However, a 40-fold increase in on-road NOx would mean that these vehicles did not deserve those high Green Scores." For those curious, the Ram 2500 pickup topped the ACEEE's "Meanest" vehicle of 2015, followed by the Chevrolet G2500 Express/GMC Savana. No diesels showed up on that list of environmentally-damaging vehicles. You can read the ACEEE's statement on VW below. Why we are suspending Volkswagen diesel Green Scores on greenercars.org by Shruti Vaidyanathan, Senior Transportation Researcher On September 18th, the Environmental Protection Agency (EPA) slapped the Volkswagen Group with a notice of violation (link is external) of the Clean Air Act for circumventing EPA emission standards for nitrogen oxides (NOx). Volkswagen has now acknowledged using so-called "defeat devices" on its diesel cars that turn on full emissions control technologies while in testing mode but allow the vehicles to emit nitrogen oxide levels up to 40 times the certified level during normal operation.
