Former Ferrari F1 chief could be new Lamborghini CEO

The word on the street in Bologna is that Lamborghini is in for a changing of the guard. Current CEO Stephan Winkelmann is tipped to step down after 14 years at the helm in Sant'Agata, likely to move to another role at Audi. And in his place, the German automaker is anticipated to appoint Stefano Domenicali. Domenicali was formerly the head of Scuderia Ferrari, rising through the ranks at Maranello to succeed Jean Todt as team principal in 2008. He resigned in 2014 to be replaced first by Ferrari US chief Marco Mattiacci and then by Marlboro man Maurizio Arrivabene as the team has struggled to find its form again. Shortly after leaving Maranello, Domenicali took up a new position at Audi, where he was rumored to be working on the company's anticipated foray into Formula One with Red Bull. But after that program was shut down in the wake of the diesel emissions scandal, Domenicali is now tipped to move back to Italy to take over the supercar business. Stefano would be the second Domenicali to head an Italian performance brand under the VW/Audi umbrella, joining Ducati CEO Claudio Domenicali (they not believed to be related). The move would also be a particularly emphatic gesture to Sergio Marchionne. The Fiat Chrysler Automobiles chief has previously lost top lieutenants to Volkswagen, most notably Luca de Meo, who headed up VW brand's passenger car marketing department before taking over at Seat. While previous Ferrari chiefs Todt and Montezemolo came up through the racing department, Marchionne assumed the chairmanship in Maranello and brought in outside talent instead. Meanwhile Winkelmann has been in charge of Lamborghini since 2005, when he was appointed by Audi to run the company it had just acquired a few years prior. Under the tenure of the German-Italian executive, Lamborghini sales have risen from 1,600 units per year to over 2,500 last year. The introduction of the forthcoming Urus crossover, birthed under Winkelmann's leadership, is expected to more than double that overall figure. Given his success in transforming Lamborghini, it isn't likely that the Volkswagen Group will simply show Winkelmann the door. Word has it that he'll receive another posting at Audi, potentially taking over the growing Quattro GmbH division in Neckarsulm. The division is responsible for all of Audi's RS models as well as the R8 – the latter of which Audi sells as many units as the entire Lamborghini division does in a year.

VW fix would have cost $335 per vehicle

Since the Volkswagen diesel kerfuffle began, Bosch, the world's largest auto supplier, has been hooked up to a bullhorn trying to make sure everyone knows its side of the story. Bosch supplied VW with the engine management testing software, including delivery and metering modules, that VW then used to skirt emissions laws in the US. Bosch told VW in 2007 that it was illegal to use the software in cars it planned to sell yet VW did it anyway, according to reports coming out in German newspapers Bild am Sonntag and Frankfurter Allgemeine Zeitung. That first warning came two years after VW started developing the small-displacement diesel, around the time that the two men pushing its development, then-brand chief Wolfgang Bernhard and engineer Rudolf Krebs, were telling their superiors that the engine needed AdBlue urea injection to pass US emissions. VW cost controllers wouldn't approve the AdBlue solution because it would add 300 euros ($335 US) to the cost of the vehicle. Bernhard and Krebs left the same year that Bosch advised VW about the software, two years before the engine went into production. That's when things get cloudy. A report in Automotive News says that when Martin Winterkorn took over in 2007 as head of the VW Group and brand, he asked Ulrich Hackenberg and Wolfgang Hatz to keep working on the engine, and "[the] engine then ended up in VW Group diesels" with that problematic software still intact. No one has yet pointed any fingers at this latter chain of command, but like a game of Clue, right now they're the professors in the library holding the candlesticks. Warnings didn't only come from the supplier: Frankfurter says VW's initial investigation has found that an engineer issued the same caution to the company in 2011. Neither Bosch nor VW would comment on the reports.

To solve diesel problem, VW might need two fixes

Volkswagen says that a fix is on the way for its 11 million vehicles around the globe that are equipped with diesel engine software that can evade emissions tests. The problem might be far more complicated than simply creating a single solution for all of them, though. According to Automotive News citing Reuters, two remedies to cover different NOx-reducing systems could be necessary, and both potentially affect performance. Earlier examples of the EA 189 diesel engine used a lean NOx trap to reduce the harmful material coming from the tailpipe. According to experts in the Automotive News report, a software update might allow the engines to achieve compliance, but that could affect fuel economy. VW already tried this route once before the scandal came to light, but tests by the California Air Resources Board still showed the figures were too high. Later, some of the 2.0 TDI engines began using Selective Catalytic Reduction that reduced NOx by injecting a urea solution into the exhaust stream. According to Automotive News, a software update for this equipment might increase the amount of the substance used. Not only would that mean topping up the fluid more often, but there still could be some reduction in fuel economy. But, since the 2-liter, 4-cylinder TDI engine that sits inside the diesel vehicles first mentioned as being affected by the issue in the US don't have a urea treatment system, VW would need to install them into these cars. VW still hasn't officially outlined its solution (or solutions) to the emissions issue but is expected to soon. The automaker's long-term evasion of regulations with these diesel engines pumped vast quantities of additional NOx into the air. The substance is known to be linked with smog and acid rain. The US Department of Justice is already beginning an investigation into the company, and politicians are pushing for harsh punishments.
