NHTSA closes rollaway investigation into 1.56M Ford SUVs

It's taken four years of study, but the National Highway Traffic Safety Administration has finally closed the books on its investigation into rollaway accusations surrounding 1.56-million Ford SUV models.
The probe, which centered on the 2002-2005 Ford Explorer, 2002-2005 Mercury Mountaineer and 2003-2005 Lincoln Aviator, ends without the federal agency calling for a recall. According to The Detroit News, the investigation was closed due to a "low number of complaints" - NHTSA documented 180 such complaints that resulted in 14 crashes and six minor injuries, but the number of incidents have been slowing. The suspected defect rate for the trucks' automatic transmissions was found to be 4.4 per 100,000 units, and the brake-shift interlock mechanism failure rate was judged to be even lower at 3.4 per 100k.

2019 BMW X7 vs luxury SUV rivals: Comparing specs and photos

Today we get our first-ever look at the first-ever 2019 BMW X7 crossover. We've actually already had our first-ever drive in an X7 Prototype. And so, we thought it appropriate to follow that up today with the first-ever X7 comparison of specs between BMW's first-ever three-row crossover with legitimate room for seven and its many high-dollar competitors. On paper, the 2019 X7 definitely seems to most closely align with the Mercedes-Benz GLS-Class. Their similar dimensions, interior space, engine choices and price would certainly imply where BMW placed the target when developing X7. We used those same elements to determine three-row vehicles likely to be cross-shopped or that should be cross-shopped. These include the Audi Q7, Land Rover Discovery, Volvo XC90 and Lincoln Navigator. Yes, the latter is a truck-based SUV as opposed to a crossover, but tell that to all the people lining out the door at the local Lincoln emporium. They do not care, and neither shall we. We also included the 2019 BMW X5, which was completely redesigned for this year and therefore not the first-ever. That makes it less appealing? Either way, lining the new X5 up with the SUV that leapfrogs it atop BMW's SUV hierarchy should provide a good idea of just how much more you get by going up a model number. Engines and model lineup Again, the X7 aligns closest with the GLS, offering a base six-cylinder in its xDrive40i model and an upgrade turbo V8 in the xDrive50i. The Mercedes engines have greater output, but the GLS still accelerates slower than the BMW. As the 2019 X5 offers the exact same engines, we would also expect the X7's fuel economy to be superior to the GLS once its estimates are announced. It should be noted, though, that the GLS offers a high-powered AMG model whereas we anticipate the X7 to offer a plug-in hybrid model comparable to the X5 upcoming xDrive45e model. The other luxury SUVs diverge in their engine choices and model lineup. The Audi Q7 offers a base turbocharged four-cylinder, as does the Volvo XC90 in its T5 model, which we left out of the above chart entirely for space reasons. That the Q7 3.0 TFSI supercharged V6 gets the same fuel economy estimates as the four-cylinder is proof positive that engine is purely around for its lower base price.

Hennessey’s 600-hp Lincoln Navigator is here

The tuners at Hennessey have begun deliveries of the 2018 Lincoln Navigator HPE600, a full-size SUV that boosts the Navigator's normal 450-horsepower output to 600 hp, announcing its arrival with a video showing the performance 'ute riding a dynamometer. Hennessey said it was a natural decision to turn to the Navigator because it has mostly the same 3.5-liter twin-turbo V6 engine as the F-150 Raptor, which it converted last year to the 602-hp 6x6 VelociRaptor. So it added engine management computer software upgrades, a stainless steel exhaust system, high-flow air induction and large front-mounted intercooler with blow-off valve. Dyno results in the video show the Navigator topping out at around 500 hp and 500 pound-feet of torque at around 3,800 rpm at the wheels; Hennessey says the 600 hp comes at 6000 rpm. The upgrades are good to take the nearly three-ton SUV from 0-60 mph in 4.8 seconds, about 0.7 seconds quicker than the standard Navigator, and run the quarter mile in 12.9 seconds at 107 mph. The tuning package will set you back $19,950, including installation. Additional options include 22-inch forged monoblock wheels, lowered suspension and Brembo brakes with six-piston calipers and 15.1-inch brake rotors. There are also HPE600 badges on the front door jambs and tailgate, and embroidered headrests. It comes with a three-year, 36,000-mile warranty. Just 200 are planned for the 2018 model. You can order it now through Hennessey or any authorized Hennessey Lincoln dealer. Related Video: Image Credit: Hennessey Lincoln SUV Luxury Performance Hennessey tuner lincoln navigator tuning
