Infiniti Vision Qe concept will preview the brand's first EV

Infiniti released a dark preview image to give us an early look at its next concept. Called Qe, the design study will make its debut in October 2023 and provide a glimpse at what the Japanese brand's first series-produced electric car will look like when it lands later in the 2020s. Details about the Qe concept are few and far between, and the dark picture published by Infiniti leaves a lot to the imagination. It shows light reflecting on what looks like a fastback-like silhouette, so we know we're not looking at a convertible or at a big, burly SUV like the QX80. We think we see four doors, but the bottom part of the car is obscured so it's too early to tell whether this is a low-slung sedan or a crossover. Out back, a rear light bar is seemingly integrated into a spoiler that's positioned above backlit "INFINITI" lettering. We'll need to be patient to find out more, but an earlier report casts a little bit of light on what to expect from the Qe. Although unofficial, it details four new Infiniti models due out in the coming years, and two are electric. The first is a replacement for the Q70. It will reportedly land by the end of 2026 as the brand's first electric car, and it will feature shorter overhangs as well as a longer wheelbase than its predecessor, which retired in 2019. The second was described by insiders as "a midsize crossover." That's all we know, but odds are the Qe previews one of these two EVs. Infiniti will fully unveil the Qe on October 24, 2023. It also pledged to announce "several stunning new models" at the unveiling event. We're notably expecting to learn more about the next-generation QX80, which was previewed by the QX Monograph concept in August 2023.

Chrysler, Nissan looking into claim that their cars are industry's most hackable

A pair of cyber security experts have awarded the ignominious title of most hackable vehicles on American roads to the 2014 Jeep Cherokee, 2014 Infiniti Q50 and 2015 Cadillac Escalade.
Charlie Miller and Chris Valasek are set to release a report at the Black Hat hacking conference in Las Vegas, Automotive News reports. The two men found the Jeep, Caddy and Q50 were easiest to hack based not on actual tests with the vehicles, but a detailed analysis of systems like Bluetooth and wireless internet access - basically, anything that'd allow a hacker to remotely gain access to the vehicle's systems.
Considering this lack of hands-on testing, the pair acknowledge that "most hackable" could be a relative term - they point out that the vehicles may actually be quite secure.

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.
