NHTSA closes Ford F-150 EcoBoost acceleration probe

Typically when we report on the findings of an investigation from the National Highway Traffic Safety Administration, it's because the government body has discovered a safety issue and prescribed a recall. In this case, however, NHTSA has closed an investigation into a reported performance deficit without ever getting to the recall stage.
The issue revolves around the Ford F-150 - specifically those equipped with the 3.5-liter EcoBoost engine - of which some 360,000 were built in the 2011, 2012 and 2013 model years. After receiving an initial 95 complaints, NHTSA opened an investigation last May - almost a year ago - into the reported issue of reduced engine power under hard acceleration. The agency has since received a total of 525 such complaints, and Ford itself reported receiving over 4,000.
Together, NHTSA and Ford determined that the problem resulted from cylinders misfiring, an issue itself stemming from water getting into the charge air cooler (CAC) mated to the turbochargers. In particularly humid or rainy conditions, water was found to get into the CAC, causing some of the cylinders to misfire, which in turn triggered the ECU to disable those cylinders in order to protect the catalytic converter from damage.

1994 McLaren F1 LM-Specification fetches $19.8M at Monterey

The botched sale of that World War II-era 1939 Porsche Type 64 may have somewhat overshadowed the RM Sotheby’s auction last weekend at Monterey, but the event wasnÂ’t without its highlights. Exhibit A: The one-of-two 1994 McLaren F1 LM-Specification supercar that we told you about a month ago netted a whopping $19.8 million at the RM SothebyÂ’s auction last weekend in Monterey, and an almost equally rare 1965 Ford GT40 Roadster Prototype also netted seven figures.  The F1 is one of 106 examples ever built and one of just two in LM-Specification (the LM stands for “Le Mans”). McLaren upgraded the standard F1 at the factory post-production, adding a 680-horsepower GTR engine, an extra-high downforce coachwork kit highlighted by the massive rear wing, race-spec dampers, two more radiators and so forth. It also gained a more comfortable interior and creature comforts, with an upgraded air conditioning, radio, new headlights and a different steering wheel. Finally, the exterior was given a coat of silver paint, replacing the factory blue. Four bidders spent four-and-a-half minutes trying to outbid one another for the car, which eventually went to an unidentified American private collector. Also successfully auctioned on Friday: the 1965 Ford GT40 Roadster Prototype for $7.65 million, which fell right in line with expectations of between $7 million and $9 million. It helped pave the way for the Mark IV race cars that won the 24 Hours of Le Mans. As a reminder, it was the first of five GT40 Roadster Prototypes ever built, with seven hardtop versions also built, and it underwent a full restoration in 1983 and a mechanical overhaul in 2003. And it sure is pretty to look at.

Meet the Greenest and Meanest vehicles of 2016

If you've been keeping track, you won't be surprised with the number one entry in this year's list of greenest cars from the American Council for an Energy-Efficient Economy (ACEEE). In fact, the top three spots on the 2016 list are all the same as they were in 2015. After that, things get interesting. For one thing, this is the first Greenest list that doesn't have any purely internal combustion engine powertrain on it. Hybrids, yes, but if you want to be one of the top 12 greenest cars this year, you'd better have some sort of electric angle. ACEEE says that the conventional, gas-powered Smart Fortwo and Chevrolet Spark just missed the cut. In a statement, ACEEE lead vehicle analyst Shruti Vaidyanathan said, "The 2016 scores are in, and plug-in electric vehicles are outpacing all other vehicle offerings in terms of environmental friendliness." Like last year, one of the noticeable vehicles missing from the green list is the Tesla Model S. One reason? ACEEE takes curb weight into account (lighter is better), and the Model S is a heavy beast. The ACEEE doesn't just look at the clean side of the ledger. It also puts out a "meanest" list. These are the vehicles that pollute the most, not only from their tailpipes, but also any pollution created during the entire manufacturing process, from mining the raw materials to the energy used to produce the vehicle at the factory. The entire list, from greenest to meanest, is done using a "cradle to grave" analysis.
