About 20k Nissan Pathfinder, Infiniti JX models recalled for potentially faulty brakes

The National Highway Traffic Safety Administration has issued a recall for the 2013 Nissan Pathfinder and 2013 Infiniti JX due to a problem with the front brakes. The problem is a result of the brake torque member (a part that attaches the brake caliper to the front suspension), which was cast improperly with a structural weakness that could possibly lead to "reduced braking, increasing the risk of a crash," according to NHTSA. How, you ask? If the part breaks, the brake caliper could move position and possibly make contact with the wheel.
Around 20,000 of these sister crossovers are being recalled, but it doesn't sound like all were equipped with the faulty component. Dealers will inspect vehicles built between December 3, 2012 and January 29, 2013, and replace components from the defective batch. The recall goes into effect next month, but until then, the official recall notice is posted below with information for how owners can contact Nissan.

The Infiniti Q60 Black S gets an F1 KERS system

This is the Infiniti Q60 Black S that will be debuting at the Geneva Motor Show, sporting some intense bodywork and an F1-inspired powertrain. It exists to draw a closer parallel between the Renault F1 program and the Infiniti brand – a relationship that's surely easier to understand in Europe than it is here, but so be it. Other than the wild bodywork, which includes a heavily sculpted front fascia, bigger side sills, two howitzer-sized exhaust pipes, and a massive rear wing, there's the F1-inspired KERS system. Exactly what that will be is up in the air; the F1 system is complex and expensive. While Infiniti says they want to engineer a road-going solution that's as similar as possible to the F1 KERS system, it's likely it'll be watered down a bit for production. View 12 Photos All in all, the 3.0-liter, twin-turbo V6 and the KERS system should combine to produce about 500 horsepower. That's all well and good, if it makes it out of concept car purgatory. Remember the Q50 Eau Rouge, the last Infiniti that got car enthusiast's undivided attention? Well, it got canceled. We're not sure what the appeal of an F1 tie-in would be to American shoppers, so who knows if the Black S will emerge as a rest-of-world special, or at all. In any event, we should have more details around Geneva, so stay tuned.

F1-inspired, 563-horsepower Infiniti Q60 Project Black S details finally revealed

Despite being first revealed at the 2017 Geneva Motor Show, Infiniti has been quite coy concerning the details of its F1-inspired hybrid super coupe, the Q60 Black S. That ends at this year's Paris Motor Show, where the company has finally spilled specific information about the car. It's technologically fascinating, even if the on-paper performance doesn't sound all that shocking. Total power output of the concept, now called Q60 Project Black S, is 563 horsepower, with final torque figures yet to be announced. That power comes from a combination of the twin-turbocharged 3.0-liter V6 found in the Q60 Red Sport 400, along with a trio of motor-generator units that have similar functionality as those found in the Renault Sport F1 car's KERS (Kinetic Energy Recovery System). One large one is connected to the rear axle and generates electricity under deceleration like most hybrids, and it can deliver 160 horsepower under acceleration. The other two motor-generators are coupled to the turbochargers. They generate power under acceleration as the turbines spin. They also act as an electrical anti-lag system, spinning up the turbines when hitting the throttle again after it has been closed in order to provide maximum boost immediately. Power for and from these motor-generators is stored in a 4.4-kWh lithium-ion battery pack. All the powertrain's power goes through a seven-speed automatic transmission to the rear wheels via a mechanical limited-slip differential. The company claims it can hit 62 mph in under 4 seconds. One of the advantages of this powertrain is that electricity is generated both on acceleration and deceleration, which helps maintain battery charge so the motor assistance can be used more of the time. How aggressive the car is with the electrical boost is determined by which mode the vehicle is in, Road, Quali (for qualifying), or Race. Road is the most conservative, whereas Quali is the most aggressive. The reason for this is that if you're qualifying, you have to go the fastest you can in a short amount of time. A digital simulation of the car running a lap in Quali mode at Circuit de Catalunya estimated it would use 15 percent of the battery charge. That means it could do a little over six laps in that mode and maintain full use of its electrical assists. Race mode conserves battery life more, since you'll want that power over the course of the race. A downside to the Project Black S hybrid system is that it's really heavy.
