2014 Infiniti Q50's novel drive-by-wire steering system recalled

The gradual replacement of mechanical components in automobiles with electronic systems brings with it definite advantages, but also poses certain potential dangers. Just think of the inevitable problems you've encountered with the computer on which you're reading these words and you'll know what we mean. But a computer crashing isn't as problematic as your car going on the fritz when its electronic systems fail.
That's what Infiniti is being reminded of with its new drive-by-wire electronic steering system. The Japanese automaker developed and installed the Direct Adaptive Steering System in its new Q50 sedan, but a small number of those cars on the road are now being recalled due to that system.
According to the National Highway Traffic Safety Administration, on a small number of examples, the Q50's optional by-wire system may fail if the temperature in the engine compartment drops below freezing. There's a backup mechanical setup in place should the electronic system fail, but NHTSA says that the backup system may also fail to engage in time to avoid a crash.

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.

Infiniti expanding lineup by 60% over next five years

Johan de Nysschen had only been at the helm of Infiniti for two years when he left for a position atop Cadillac. But in that time, he indeed left his mark on the brand. Most visibly, there was the drastic Q-ification of the company's vehicle naming strategy, but beyond that were big plans to beef up the Infiniti brand with the goal of making it a fully competitive luxury automaker.
Autoblog spoke with Michael Bartsch, vice president of Infiniti Americas, during Monterey Car Week, and he confirms Infiniti's brand direction is "still exactly as Johan presented it." Over the next five years, the company's portfolio will expand by 60 percent, and that will be aided with additional engine and transmission plants, most notably the recent collaboration with Daimler to build 2.0-liter turbocharged four-cylinder engines.
Infiniti's lineup will grow to include eight sedans/coupes and five crossovers/SUVs.
