2020 Ford Explorer nabs IIHS Top Safety Pick+ rating after updates

The 2020 Ford Explorer has been named a Top Safety Pick+ by the Insurance Institute for Highway Safety, the agency's best rating. The redesigned Explorer initially fell short of that mark, however, only making the grade after Ford introduced a running change to the vehicle's design starting in May 2020 — a change made to the 2020 Lincoln Aviator as well. To achieve a Top Safety Pick+ award, a vehicle must have a Good performance rating in all six of the agency's crash tests. It also must have Acceptable or better ratings for all of its available headlamps and must earn Advanced or Superior ratings for its automated collision avoidance systems in tests of their performance against pedestrians and other vehicles. The 2020 Explorer initially achieved only an Acceptable performance in the IIHS's driver's-side small-overlap crash test, as the agency found a risk of injury to the driver's left foot due to intrusion into the footwell. Ford subsequently modified the design of the front subframe in a running change to Explorers and to Lincoln Aviators built after May 2020. The modified Explorer was re-tested, and this time the model achieved a Good performance in the driver's small-overlap test. That, combined with a Superior performance in both tests of the standard collision-avoidance system plus Acceptable ratings for both headlight systems, pushed the 2020 Explorer over the goal line to Top Safety Pick+. The Aviator, which shares the Explorer's platform, has received the same modification and achieves the same crashworthiness ratings. However, its standard headlights are judged Marginal, and therefore the 2020 Aviator achieves only the Top Safety Pick rating (even though its optional curve-adaptive LED headlights are judged Good).

A cool boost to turbocharger performance

Since the advent of the forced-induction engine, we have been looking for ways to get every drop of performance we can. There are many approaches to getting additional power using better intercooling, water injection, or even adding nitrous oxide. One take on a short instant burst of power is being researched by Mahle and involves providing supercooled air to an engine, which allows it to burn a leaner fuel mixture and produce more power. The supercooling idea is not new and was examined by Ford in 1993 on the Mustang Mach III concept car, then brought up again in 2003 with the SVT F-150 Lightning concept. Ford called its system the SuperCooler; it was designed to work with any turbocharged or supercharged engine equipped with a water-to-air intercooler. The system on the Lightning concept used a small tank of antifreeze that was hooked up to the truck air conditioning compressor. The air conditioning compressor cooled the antifreeze down to about 30 degrees. The other side of the tank was hooked up to the air-to-water intercooler, which usually had a temperature over 100 degrees. Once the antifreeze was circulated from the tank into the intercooler, it would lower the intercooler temperature and provide for a cooler, denser air charge into the engine; the result was around 50 extra horsepower for a burst of about 30 seconds to a minute, depending on the size of the tank. The system for the Lightning was to be offered as a $750 option and would have been targeted towards drag racers and the like, as it could be used for a run down the drag strip and then re-cooled by the time the truck was back in line. The system was fairly non-intrusive – it only weighed about 25 pounds and did not require a new compressor or intercooler. But as with many concepts, it was ultimately scrapped. The technology was always stuck in the back of my mind, but with larger and more powerful engines being produced it could not find its place. With the advent of new fuel economy standards, we have seen small-displacement turbocharged engines pop up and they seem like the perfect candidate for this type of technology. Ford's EcoBoost 1.0-liter three-cylinder turbocharged engine, as used in the Fiesta and Focus, is one such candidate for this technology. It would add a negligent amount of weight but could provide a boost of 10 to 20 horsepower when needed, like merging onto the highway or catching up to traffic.

Ford considering return to Le Mans with new EcoBoost LMP2

If you want to see a Ford racing prototype, you need look no further than the United SportsCar Championship, where the Blue Oval fields two Daytona Prototypes powered by an EcoBoost-branded 3.0-liter twin-turbo V6. But according to the latest rumors, that may not be enough for Ford, which has as much brand to promote overseas as it does back home.
That could be why Racer magazine is reporting that Ford may be poised to return to Le Mans in the coming years. As we all know, Ford competed at Le Mans in the mid-through-late '60s, bringing home four consecutive overall wins with the legendary GT40. The new program would not, according to Racer, seek to relive those glory days, but would instead compete for class wins in the LMP2 category.
Currently, LMP2 regulations are somewhat split between the United SportsCar Championship in North America on the one hand and ACO-sanctioned series like the European Le Mans Series, Asian Le Mans Series and FIA World Endurance Championship on the other, but plans are underway for the regulations to be unified in time for the 2017 season. That could be when Ford is targeting its return, allowing it to compete on both sides of the Atlantic to maximize its exposure.
