Nissan Rogue, Pathfinder and Infiniti QX60 recalled for loose lug nuts

Nissan has announced a small recall affecting 334 vehicles built just a few months back. 2014 Nissan Rogue and Pathfinder and 2014 Infiniti QX60 CUVs built between March 7 and March 10, 2014 could be susceptible to a loose lug nut on the passenger side wheels.
We shouldn't have to explain why a loose lug is a bit of an issue. Thankfully, it's also a ridiculously easy fix. Nissan obviously recommends reporting to your local dealer - and it will begin notifying owners of affected vehicles - but this is one of those rare recalls that has an easy DIY element to it.
Take a look below for a brief bulletin from the National Highway Traffic Safety Administration.

Formula One speeds towards radical thousand-horsepower shakeup

The teams, the drivers, the fans, the circuits... few, if any, were satisfied with how Formula One has shaped up since the current regulations took hold last year. But that doesn't mean they aren't working on it. At a recent meeting of the F1 Strategy Group, the leading parties in the sport outlined a new framework that would radically shake up the cars themselves while keeping costs in check. And the biggest change could see the engines producing around 1,000 horsepower. Although a proposal put forth by Ferrari to ditch the current V6 hybrid engines in favor of new twin-turbocharged units was rejected by Honda and Mercedes, the members of the group approved in principal to increase the fuel flow in the existing engines to dramatically boost output. As it stands, the current 1.6-liter turbocharged V6 engines develop around 600 horsepower, with an additional 160 or so kicked in by the electric Energy Recovery System, for a combined output of about 760 hp. What's not clear at the moment is whether the increased fuel flow would necessitate either the return of mid-race refueling (currently banned) or the installation of larger fuel tanks. Red Bull and McLaren also submitted proposals to radically redesign the shape of the cars as well, however a more evolutionary approach was adopted instead. Though far from finalized, the new design would keep the same basic form of the current chassis, but with adjustments to make them more aesthetically pleasing while producing more downforce. Wider tires are also said to be part of the mix. With more power and more grip from the tires and aero, the resulting cars would most certainly end up going much faster than the current ones, which are already starting to nudge the lap records at some of the circuits, many of which were set during the V10 era. The F1 Strategy Group is made up of representatives of the FIA, Formula One Management and six leading teams. The next step will be for the teams' technical directors to iron out how to implement what their bosses have agreed to. If they settle the details fast enough, the revised regulations could be pushed through in time for next season.

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.
