Shelby GT500 laps N"urburgring in under 7:40?

A couple of weeks ago we brought you footage and official times of the new Chevy Camaro Z/28 lapping the Nürburgring. With a 7:37.47 lap time, the Z/28 emerged as the fastest muscle car ever to lap the circuit. But what was missing from that picture was how fast the king of all Mustangs, the Shelby GT500, could manage to lap the Nordschleife.
Ford never released any information or footage of the GT500 on the Nürburgring that we were aware of - that is, until the guys at SVTPerformance.com put in a request for Mustang videos. Among the clips they received was never-seen, in-car footage of the Shelby GT500 lapping the circuit. And boy did it hustle.
Although not quite official, the video seems to show the GT500 lapped the venerated German track in a touch under 7:40. That would make it a tick or two faster than the Camaro ZL1 - but what of the Z/28? By Chevy's quoted time, the Z/28 is still faster than the GT500, but SVTPerformance suggests GM may have fudged the numbers a bit and scrubbed half a second or so off their lap time.

GM being sued over imploding Bosch fuel pumps in Duramax diesel trucks

Texas-based law firm Hilliard Martinez Gonzalez (HMG) this week filed a class-action lawsuit against General Motors over an alleged issue with Bosch CP4 fuel pumps. The suit claims Bosch designed the CP4 pump to work with European diesel fuel, which is thicker than U.S. diesel. When GM installed that pump in the 6.6-liter Duramax engine used from the 2011 to 2016 model years, the lawsuit claims the thinner U.S. fuel didn't provide enough lubrication, allowing air pockets to form in the fuel pump. That, in turn, allegedly let metal rub against metal inside the pump, causing the pump to eventually disintegrate and "send thousands of metal shards into the fuel injection system and every part of the engine." The Detroit News reported on the most recent lawsuit filed in Michigan's Eastern District Court, but the case is another piece of nationwide legal maneuvering going on since at least last September. Every U.S. truck maker used the Bosch CP4 fuel pump, and HMG originally went after all of them, as well as Bosch. On September 30, 2018, HMG filed a class-action suit in Texas on behalf of eight plaintiffs. The law firm wanted to prosecute the affair under RICO — the Racketeer Influenced and Corrupt Organizations Act — and named 10 defendants: FCA US LLC, FCA North America Holdings, LLC, F/K/A Chrysler Group, Fiat Chrysler Automobiles, N.V., Ford Motor Company, General Motors LLC, Robert Bosch GmbH, Robert Bosch LLC, VM North America, Inc., and VM Motori S.P.A.  The firm filed another suit in Florida on Nov. 2, 2018, against the same 10 defendants, again under the RICO statute, this time on behalf of more than 30 plaintiffs. We don't know how many other suits might have been filed, but the two suits mentioned apparently didn't have legs — the courts dismissed both quickly. So HMG shifted its strategy away from the RICO angle, and focused its efforts on GM, filing suit in California on Nov. 20, 2018. Instead of trying to catch 10 fish with a small net, HMG wants to score one fish with a big net. The results have borne more promise for the plaintiffs. In July this year, a judge in California denied GM's motion to dismiss, noting "the alleged defect is central to the vehicleÂ’s function." This latest suit filed on Aug. 6 in Detroit singles out GM again.  The Bosch CP4 is known to be problematic, however.

EPA says fuel economy test for hybrids is accurate

The EPA says it stands behind its fuel economy test for hybrid vehicles following controversy about the testing process after Ford C-Max Hybrid customers and automotive journalists alike struggled to achieve 47 miles per gallon, the advertised mpg number, Automotive News reports. Ford responded to the issue almost two weeks ago by claiming that a 1970s-era EPA general label rule was responsible for the inaccurate mileage numbers, rerating the C-Max Hybrid's mpg numbers and offering customers rebates. Ford later said it didn't overstate the C-Max Hybrid's fuel economy and that it was surprised by the low numbers.
Ford technically didn't do anything wrong because it was following the general label rule, but agency regulator Christopher Grundler says the automaker was exploiting a loophole when it came up with the hybrid C-Max numbers, and that the testing process remains accurate. The general label rule allows vehicles that use the same engine and transmission and are in the same weight class to share fuel economy numbers, but it doesn't take into account other factors such as aerodynamic efficiency, which affects hybrids more drastically than non-hybrid vehicles. Ford originally used the Fusion Hybrid economy figures for the C-Max Hybrid and claimed the engineers didn't realize that its aerodynamic efficiency would affect fuel economy as much as it did.
