Winterkorn kept diesel scandal secret, letter claims

Former Volkswagen Group CEO Martin Winterkorn allegedly kept quiet for two weeks about emissions defeat devices in the company's models. US officials eventually made the automaker's deception public on September 18th. "In the conversation on 03.09.2015 with the regulator CARB (California Air Resources Board), the defeat device was admitted," an employee told Winterkorn on September 4, according to Reuters citing Germany's Bild am Sonntag. Based on this information, Winterkorn had plenty of time to admit the problem. Evidence like this letter continues to suggest top figures knew about the emissions problem. In addition, a separate Bild am Sonntag report recently claimed that an employee emailed Winterkorn in May 2014 to tell him US regulators could discover the cheating. In the lower echelons of the company, the deception was allegedly an open secret among engineers as early as 2006, and people kept quiet even after workers tried to admit what was happening. This culture of secrecy seems to go even deeper than just the diesel emissions scandal. For example, engineers admitted that they cheated on CO2 tests to meet the company's strict standards. According to Green Car Reports, these problems also affected the US. In 2004, an Audi worker in America allegedly discovered an issue with the exhaust gas temperature sensor in some vehicles, but a German executive said not to admit the problem to US regulators. It's not clear whether any high level employees tried to fix the diesel emissions issue or if they simply kept the problem hidden. The company's internal report, which is due in the latter half of April, might address that concern. So far, the VW Group has said only a small group of people caused the scandal. However, these many allegations to the contrary make that claim difficult to believe. Related Video:

The 2018 Audi SQ5 looks mean and switches to turbo power

Audi's huge Q8 wasn't the only crossover introduced by the German automaker at this year's Detroit Auto Show. Right alongside it came the 2018 SQ5, the brand's high-performance midsize crossover. This newest version ditches the previous generation's supercharger in favor of a turbo for its 3.0-liter V6. The powertrain is similar to the one used in the latest S4 and S5. Horsepower remains unchanged compared to the last SQ5 at 354, but torque sees a healthy increase to 369 pound-feet, and it's available anywhere from 1,370 to 4,500 rpm. The car itself weighs about 77 pounds less, too. It's a combination that should make the SQ5 pretty entertaining off the line. Coupled to the turbo engine is an eight-speed automatic and standard all-wheel drive. Power delivery and handling can be enhanced with a Quattro sport rear differential that can shuffle power left and right to aid cornering. Audi says the torque vectoring system can send almost all rearward power to one wheel as necessary. The differential is available as part of the S sport package, which comes with other upgrades including air suspension. The suspension gives the crossover a lower ride height by default. Both height and firmness can be adjusted, and it offers an "offroad" position that raises the car for maximum ground clearance. Inside, the SQ5 comes with a sportier interior than its Q5 counterpart. It comes with prerequisites such as a flat-bottomed steering wheel and more-bolstered seats. Audi also provides a Bang & Olufsen sound system and standard Apple CarPlay and Android Auto. The cabin experience can be further augmented with Audi's Virtual Cockpit LCD instrument panel, as well as driving assists such as a variable-ratio steering rack and adaptive cruise control that can handle stop-and-go traffic from 0 to 40 mph. Audi will begin selling the new 2018 SQ5 here in spring of 2017. Pricing for it and the Q5 has not yet been released. Related Video:

Audi exec denies plans for turbo R8

Sometimes smoke doesn't lead to fire. Rumors indicated Audi might drop a turbocharged engine into the latest R8, but now a top executive is throwing a bucket of cold water onto the burning speculation. "The performance potential of this current engine means we don't need to even look at turbocharging at this point," Jurgen Konigstedt, Audi development boss for V6, V8, and V10 engines, said to CarAdvice. He also said sticking with natural aspiration offered a better sound and sharper throttle response than going with forced induction. "There is less emotion with a turbocharged engine," he said. Konigstedt admitted there was a serious discussion about turbocharging the R8. The argument just didn't win out. "If we feel that people absolutely want a turbocharged engine, then we will have to consider it," he said to CarAdvice. Audi just launched a new generation of the supercar. The 2017 R8's 5.2-liter V10 will be available in two tunes: with 540 horsepower in the standard coupe or 610 hp in the Plus. Rumors have persisted about a smaller, forced induction powerplant at the bottom of the range. Some reports suggested a twin-turbo V6 behind the driver, but others said the electrically supercharged 2.5-liter inline five was a candidate. The reason for the entry-level addition was tied to lowering the taxes on the R8 in markets like China. Related Video:
