Nissan and Infiniti recall 1.2 million vehicles because backup camera might go blank

Nissan North America has issued a recall for more than 1.2 million vehicles due to the ability to change backup camera settings to the point where there is no image in the display. The recall, which was filed with NHTSA on Sept. 12, 2019, includes cars, trucks, crossovers, SUVs, vans, and coupes across both the Nissan and Infiniti lineups.  Reported by Automotive News, NHTSA recall No. 19V654000 affects a total of 1,228,830 vehicles across two brand lineups and more than two dozen models. It includes the 2018-2019 Nissan Altima, Frontier, Kicks, Leaf, Maxima, Murano, NV, NV200, Pathfinder, Rogue, Rogue Sport, Sentra, Titan, Versa Note, Versa sedan; and 2018-2019 Infiniti Q50, Q60, QX30 and QX80. It also lists the 2019 Nissan GT-R and Taxis, as well as the 2019 Infiniti QX50, QX60, Q70, and Q70L. According to the recall, it is possible to adjust the backup camera and display settings "such that the rearview image is no longer visible and the system will retain that setting the next time the vehicle is placed in reverse." Although this type of occurrence would be extremely rare and most likely a mistake made by the driver, its real possibility means all of these cars are technically breaking the law. Federal Motor Vehicle Safety Standard (FMVSS) No. 111, "Rear Visibility," says so. According to Automotive News, this recall is not limited to the United States and also affects vehicles in Canada, South Korea, and Israel. The recall begins Oct. 19, 2019, and Nissan will provide affected customers with a free software update to fix the issue.        

Nissan Juke to get higher-performance Nismo RC model

It's hard to find more giggles for your crossover dollar than the Juke - regardless of how you feel about the way it looks, the singularly styled nichemobile from Nissan is very entertaining to drive. Yet we've always felt that the platform had more in it, and evidently its Japanese parent agrees, having recently bracketed the googly-eyed turbocharged CUV with a new Nismo model and the barking mad built-to-order Juke R. At present, neither the Juke Nismo or the GT-R-powered Juke R are sold in North America, but the former has already been confirmed for sale here.
Even when it does reach our shores, there will still be a heck of a lot of whitespace between the mild performance upgrades of the standard Nismo and the half-mill R model, and to hear the UK's Car tell it, Nissan has plans to plug that gap, too. According to its report, the automaker will shortly offer a Juke Nismo RC that will have roughly 20 horsepower more than the basic Nismo (which itself has 197 hp, nine more than the base Juke). The RC will apparently feature a lower, stiffer suspension, upgraded brakes and a unique exhaust and intake for a snarlier soundtrack. Both front-and all-wheel drive models are planned, as are manual and CVT transmission choices.
No word yet on the RC's pricing or even North American availability, but the regular-strength Juke Nismo is expected to arrive shortly, and Nissan is also said to have big plans for its performance nameplate, so we wouldn't rule it out.

Infiniti's new VC-T changes the rules of small turbocharged engines

The upcoming Infiniti QX50 crossover does not get our pulse racing, no matter how shapely the QX Sport Inspiration concept that previews it may be. No midsize SUV does, to be fair. But it has something special under the hood – the world's first production variable-compression-ratio engine. That means the QX50's 2.0-liter turbo four, which makes 268 horsepower and 288 pound-feet of torque, will have up to 27 percent better fuel economy. Here's how it works. The trend of moving to smaller, turbocharged engines carries with it one big falsehood. Under low load when the turbo isn't needed, these engines are less efficient than an equivalent engine without a turbo because of the low compression ratio the turbo requires. That is, if you never need the extra power, you're wasting fuel. Turbocharged (and supercharged) engines use a lower compression ratio to prevent detonation. When you force extra air in a cylinder and mix it with fuel, it's more likely to prematurely go boom. Lowering the compression ratio prevents this problem, but it's less efficient. Infiniti's VC-T promises the best of both worlds, with a compression ratio that ranges from 8.0:1 for high-power turbo needs to a 14.0:1 ratio for fuel-sipping efficiency. At its heart the VC-T engine is a simple idea, but it's complicated to explain. Consider yourself warned. The photo below from Infiniti serves as a good visual overview. For the truly nerdy, this patent application covers the mechanical concept. Instead of having the pistons connected to the crankshaft, Infiniti's engine has a pivot arm with a connection on each end. One end connects to the piston, the other connects to a second lower shaft, which is controlled by an actuator arm. At any given time the engine's pistons move up and down according to the lobes on the crankshaft. But the actuator arm can change the angle of the pivot arm up and down. That is, the pistons still move in the same motion with the same stroke, but phase the entire stroke up or down. Move the pivot up and there's less room at the top, which means a higher compression ratio. Move the pivot down and the compression ratio goes down, too. As an added bonus, the lower shaft eliminates the need for counter-rotating balance shafts. Infiniti says this system works constantly and can vary the compression ratio to any number between 8:1 and 14:1. It also uses electronic variable valve timing on the intake valves to switch into Atkinson-cycle combustion for greater efficiency.
