2022 Infiniti QX50 starts at $40,025

Infiniti upped prices on the 2022 QX50, but at least some of the MSRP increase goes toward new features. Nissan's luxury arm made ProPilot Assist standard for all five trims, the driver assistance suite includes tech like steering assist, intelligent cruise control, speed limit assist, and distance control assist. Apple CarPlay is another included item for next year's model, as well as an auto-dimming rearview mirror, and more soft-touch luxuries for the rear quarters with keyless entry able to be activated by the rear doors now, LED welcome lights in the rear door handles, and a USB-C port for the aft chairs. The first four grades are front-drivers; adding all-wheel drive adds $2,000 to the tab. For 2022, top front-wheel drive Autograph bows out, making AWD the de facto standard. The trims and their pricing after the $1,025 destination fee, plus their differences from the 2021 model, are: Pure: $40,025 ($950) Luxe: $43,375 ($750) Essential: $47,825 ($2,000) Sensory: $52,525 ($1,400) Autograph AWD $57,975 (no change) On top of the other newly standard equipment, the Essential trim picks up a heated steering wheel, 16-speaker Bose Performance Series audio, climate-controlled front seats,  Luxe fits "leather-appointed seats," and offers an updated Appearance Package for $1,200. The bundle is composed of black mirror caps, body color rear diffuser, black mesh grille, black fender accents, a black liftgate finisher, and 20-inch black-painted, machine-finished wheels. A graphite headliner finishes the package inside.   Sensory snares some features formerly reserved for the Autobiography, like "leather-appointed" perforated seats, four-way passenger power-seat lumbar adjustment, heated outboard seats in the second row, ultrasuede interior trim, and a motion-activated liftgate.  The eight-strong color palette welcomes a new Slate Gray hue. Mechanicals don't change, every model powered by a 2.0-liter inline-four cylinder with 268 horsepower and 280 pound-feet of torque, routing its output through a continuously-variable transmission. The 2022 Infiniti QX50 should reach dealers later this month.

2014 Infiniti Q50S

Ten years ago, nearly to the day, I took delivery of a brand-new 2004 Infiniti G35 6MT. The sporty rear-wheel drive sedan, equipped with its throaty 260-horsepower V6, slick manual gearbox and limited-slip differential replaced my 2001 BMW 330i because the Japanese competitor touted a product that was roomier, better equipped, quicker and lower priced. The G35 trumped the German in nearly every measurable category - at least on paper.
The 2014 Infiniti Q50 is the direct descendant, albeit two generations later, of the car I owned a decade ago. It is dimensionally about the same size, but it has gained more than 300 pounds of mass thanks to numerous safety upgrades and technical innovations. The additional weight is largely dismissed by a larger and more efficient powerplant that delivers an additional 68 horsepower, a welcome arrival, but the manual gearbox that charmed enthusiasts has been pushed out of the picture by a mandatory seven-speed automatic transmission.
As it has in the past, Infiniti touts its all-new Q50 as a luxury sport sedan worthy of the title. Decades ago, impressive performance statistics may have sealed the deal. Yet there is much more to the assignment today, as the model must offer premium appointments, sophistication and engaging driving dynamics if it's going to entice and capture the next-generation of young, premium buyers - much like the G35 did for me ten years ago.

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.
