Infiniti confirms all-new sports sedan will debut in Detroit

While the automotive world may currently be focused on the Los Angeles Auto Show, those looking to stay ahead of the curve have their sights set farther down the road. One such automaker is Infiniti. On the first of the LA press days, the Japanese luxury brand has announced an all-new model to debut in Detroit this January.
According to Infiniti, an all-new model will be unveiled at the 2013 North American International Auto show. The debut will be accompanied by a performance from world renowned Cirque Du Soleil as well as a live stream simulcast of the event.
It's unclear whether Infiniti will be showing a redesign of the G sedan, which has been spotted testing, or a new sub-G compact performance-luxury four-door. We will know for sure on January 14 when we bring you news form the Infiniti stand.

2023 Infiniti QX60 adds three-year maintenance plan, higher price

Infiniti has published pricing information for the 2023 QX60. The second-generation crossover enters its second model year on the market with price increases across the board, a handful of new features and a three-year maintenance plan called Infiniti Premium Care. Buyers still have four trim levels to choose from. Pricing for the full range (including the $1,195 destination charge) is as follows: QX60 Pure: $50,395 ($2,520 more than in 2022) QX60 Luxe: $56,445 ($2,520 more than in 2022) QX60 Sensory: $59,795 ($2,420 more than in 2022) QX60 Autograph: $63,795 ($2,420 more than in 2022) Note that those figures correspond to the front-wheel-drive QX60. Motorists who want all-wheel-drive will need to pay and extra $2,000 regardless of trim. Small updates to the list of standard features complement the price hike. Every trim level gains a wireless device charger and a frameless rear-view mirror for 2023. The Luxe model gets gloss black trim on the rear bumper, while Sensory and Autograph trims receive gray trim. Heated front seats, 18-inch wheels, a 12.3-inch display for the infotainment system and a power-operated hatch continue to come standard. Infiniti Premium Care is the final addition to the QX60 line-up. Announced in June 2022, and offered on every 2023 Infiniti model, it's an integrated maintenance plan that includes three years' worth of engine oil and brake fluid changes, tire rotations, inspections, cabin air filter replacements, tire road hazard coverage, and, on some models, car rental assistance.

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.
