Here's what the UAW will be angling for in next year's contract negotiations

The United Auto Workers union is about to enter a new round of negotiations with the Detroit Three automakers, and this time, the focus is on the end of the two-tier wage system. Introduced in 2007, the two-tier wage system was enacted to allow General Motors, Ford and Chrysler to categorize its hourly employees under two categories: Tier 1 for veteran employees with full rights and benefits, and Tier 2 for short-term or entry-level employees compensated under a different schedule. The idea was that the system would permit the automakers to invest more in their plants and hire new employees as part of their respective recovery plans without being saddled with all the costs associated with hiring full-time employees. Now that the automakers are (more or less) back on their proverbial feet, however, the UAW wants to see an end to the two-tier system, and will likely make that a center-point of its negotiations next year to replace the current arrangement that is scheduled to end in September 2015. Not all members of the UAW will necessarily be interested in ending the two-tier system, however. According to The Detroit News, some Tier 1 workers may be more interested in negotiating a raise in their hourly rate – something which they haven't received in almost a decade. Tier 2 workers, meanwhile, may be more motivated to keep the tiered system in place, as their arrangement includes provisions for profit-sharing payments that have seen the automakers pay out billions to so-called short-term employees in lump-sum payments. Reconciling the two competing demands from two categories of union members and presenting a united front in negotiations may prove the biggest challenge for the UAW's new president, Dennis Williams. And with the right to strike – something which was suspended during the last round of negotiations in 2011 – the union has a bigger bargaining chip in its pocket.

Did a US automaker blow the whistle on Hyundai, Kia fuel economy issue?

In all of the most hotly contested mainstream segments of the motoring universe, the difference of one mile per gallon averaged on a widow sticker can mean the difference between a sale and a walk-off - to say nothing of two or three mpg. So, when Hyundai and Kia were forced to reveal that many of their 40-mpg ratings were actually 38s and 37s, well, it made for big news.
It also, conceivably, made for a competitive disadvantage immediately, when the Korean automakers' products were being shopped versus the guys down the block. And it's that disadvantage that makes a recent story from Automotive News so juicy.
AN is reporting that Margo Oge, former head of the Environmental Protection Agency's Office of Transportation and Air Quality, got a tip in 2010 that Hyundai/Kia were "cheating" to get its impressive fuel economy numbers. The tip, said Oge (who retired from the EPA this past September), came from a senior vice president from a domestic automaker. The source was credible enough for Oge to launch an audit of the Hyundai figures, which ultimately lead to the debacle that we reported on a few months ago, and that the Korean company has been trying to bounce back from ever since.

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.
