2015 Roush Mustang lineup officially revealed

Just last week, Saleen revealed initial details of its tuning program for the new Ford Mustang. And now Roush is following suit.
Available in three stages - based on the V6 (RS), EcoBoost (RS1) and V8 (RS2) models - the 2015 Roush Mustangs all feature the venerable Ford tuner's latest R7 aero kit complete with remodeled fascia, five-blade grille, gaping air dam with integrated driving lamps and splitter. Around back there's a one-piece deck spoiler and "race-inspired lower aero-valance."

2020 Ford Explorer, Lincoln Aviator reportedly facing numerous QC issues

A lengthy report in the Detroit Free Press delves into a range of quality control issues confronting the 2020 Ford Explorer and its luxury platform sibling, the 2020 Lincoln Aviator. Freep says it's been following the issue for two months, tapping various unnamed sources for information on the automaker's unorthodox route to resolution. Seems the problem is Explorers and Aviators leaving the production line at the Chicago Assembly Plant with flaws in areas like the chassis, transmission and suspension, said vehicles trucked to Ford's Flat Rock Assembly Plant (FRAP) outside of Detroit for repair. The estimates range from 10,000 to 18,000 vehicles affected, numbers so high that Ford has sought help from Roush Engineering in nearby Allen Park, and brought workers and managers from other plants in the Midwest to FRAP to get vehicles repaired and shipped to dealers. Ford hasn't shared the nature of the problems with anyone outside the company, including dealers and customers. Freep's sources are said to include workers who have provided photos of certain vehicles and of tents used to house parts at the FRAP repair site. The Explorer chassis allegedly has an unidentified problem that engineers are using X-rays to diagnose, and the transmission is having problems sensing when it's in park or going into park. Both the Explorer and Aviator have come off the line with HVAC units that only blow hot air. And the Aviator's height-adjustable suspension enters failure mode for unknown reasons. These come on top of quotidian mishaps common to every new vehicle, but that are meant to be sorted in pre-production, like missing emblems and trim pieces. They also come on top of a recall in early August issued for the Explorer and Aviator concerning the instrument cluster and parking brake, and another at the end of August over rear seatbacks that could collapse in a crash. An automaker spokesperson told Freep, "Making updates to preproduction models based on all-new platforms as they roll off the assembly line – is standard industry practice." Except these aren't pre-production, these are early production vehicles that paying customers and dealers are waiting for, and some of the affected vehicles have been pulled off dealer lots. Dealers say they are fine waiting for the trucks to get sorted out, and they'd rather have Ford fix the problems before the SUVs go to customers.

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.
