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.

Motorweek goes retro with '80s hot hatch shootout

Motorweek's decades of history on television make it the perfect medium to look back into the automotive past and see how things are different now. It recently added old road test videos to its YouTube channel of the Acura NSX and Toyota Supra, as well as the Ferrari F40. For one of its newest flashback clips, Motorweek has exhumed an affordable five-car challenge of 1986's premiere hot hatches.
By today's standards, this is an eclectic field that features fondly remembered classics like the Volkswagen GTI 16-valve and Acura Integra. However, it also throws in some nearly forgotten contenders like the Dodge Colt Turbo and Ford Escort GT. The angular Toyota Corolla FX16 GT-S rounds out the group.
It's fascinating to watch Motorweek run the quintet through the slalom, down the drag strip and on various roads. What's most striking in this clip is the difference in the definition of a performance car between then and now. With its 16-valve, 1.8-liter four-cylinder, the GTI is the burliest of the contenders with 123 horsepower, but it still takes 8.8 seconds to reach 60 miles per hour. By today's standards, that would make it a plain-jane economy car, and not even a particularly quick one.

Ford finds flex-fuel engine design plays big role in emissions output

How bad is ethanol for your engine? There's been a lot of debate on this issue as the US considers upping the biofuel content in the national gasoline supply from 10 percent (E10) to 15 percent (E15). The ethanol industry and some scientists say higher ethanol blends show no "meaningful differences" in new engines while the oil industry says ethanol creates health risks. Researchers working at the Ford Research and Innovation Center decided to take a closer look at how a wide range of gas-ethanol blends - E0, E10, E20, E30, E40, E55 and E80 - affected the emissions coming out of a flex-fuel 2006 Mercury Grand Marquis. To see the full report, printed in the journal Environmental Science & Technology, requires payment, but there is an abstract and Green Car Congress has some more details. The gist is that, "with increasing ethanol content in the fuel, the tailpipe emissions of ethanol, acetaldehyde, formaldehyde, methane, and ammonia increased." At least NOx and NMHC emissions decreased. The researchers say that the effects are due to the fuel and "are expected for all FFVs," but that the way that a manufacturer calibrates the engine will affect NOx, THC, and NMOG emissions. It's this last bit that's important, since the researchers found, "Higher ethanol content in gasoline affects several fundamental fuel properties that can impact emissions. ... These changes can have positive or negative effects that can depend on engine design, hardware, and control strategy. In addition to direct emissions impacts, higher ethanol content fuel can also provide more efficient combustion and overall engine operation under part-load conditions and under knock-limited higher-load conditions." So, as we head towards more ethanol in our fuel supply (maybe), manufacturers are going to need to learn how to burn it most efficiently.
