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.

Ford Focus RS ready to make our hot hatch dreams real

Ford's current hot hatch siblings the Fiesta ST and Focus ST are already two pretty great entries into the segment, but there's always a desire for a little more. Thankfully, it looks like the Blue Oval is ready to satiate that need because it's continuing to test the even more powerful Focus RS around Europe. According to our spy shooters, these shots come from near the Nürburgring.
As with previous photos, Ford engineers continue to heavily camouflage the front end of the RS prototypes, but there's a big difference here. Unlike earlier ones, this example appears to have a closer-to-production-ready front bumper rather than just a horizontal strip for the license plate. That may point to development getting somewhat closer to wrapping up. Although, this one lacks the larger rear wing from prior testers, and the exhaust also appears to be a work in progress with the rear diffuser covered in mesh in these latest shots.
The RS is rumored to be using the 2.3-liter turbocharged four-cylinder from the 2015 Mustang, but power is reportedly turned up from 310 horsepower in the 'Stang to somewhere between 325 hp and 350 hp for the Focus. Routing all that just through the front wheels could be a recipe for serious torque steer, and all-wheel drive is potentially being used for better traction.

VW going turbo-only in 3 to 4 years

This really was a matter of when, rather than if. Volkswagen will apparently be the first manufacturer to phase out naturally aspirated engines in favor of turbocharging its full slate. VW is kind of responsible for ushering in this push towards small-displacement, turbocharged engines that's taken the industry by storm. When it dropped its direct-injection, 2.0-liter turbo in the 2005 GTI it demonstrated that strapping an iron long to an engine can enhance the powertrain as a whole. VW made fuel economy gains, while also giving a linear, non-laggy turbo experience that it has replicated, model-after-model, to this day.
Speaking with The Detroit News, Volkswagen's executive Vice President of Group Quality, Marc Trahan, told the paper that, "We only have one normally aspirated gas engine, and when we go to the next generation vehicle that it's in, it will be replaced. So three, four years maximum."
Really, it's hard to get teary-eyed about either of these engines going away. VW has access to smaller powerplants that could easily match the performance of the 2.5 five-cylinder and the 3.6 V6, while gobbling up less fuel and providing a better driving experience. What we are sad about is that a similar statement about the extinction of NA engines came from the Vice President of Powertrain Engineering at Ford, Joe Bakaj. We'd certainly get teary-eyed over a world without Ford's excellent 5.0-liter V8.
