Infiniti's fastback 2021 QX55 crossover shows its stylish rear end

First announced in August 2019, the Infiniti QX55 will finally make its global debut on Tuesday, November 17. Nissan's luxury division released a preview image that gives us the best look yet at the next addition to its range. The QX55 is closely related to the QX50 crossover under the sheetmetal, but it stands out from its more family-friendly sibling with a rakish, fastback-like roofline that will inevitably attract the coupe label. It will be to the QX50 what the BMW X4 is to the X3. Although we haven't seen its front fascia yet, Infiniti's preview image shows the rear end wears horizontal LED lights that stretch deep into the quarter panels, along with a roof-mounted spoiler. We were pleasantly surprised by the QX50's upmarket interior, so we're expecting a comparable degree of opulence in the QX55. It's too early to tell if Infiniti will simply copy the 50's cabin layout and paste it inside the 55, or if the latter will receive a look of its own. Similarly, technical specifications won't be published until the model's introduction. We expect that the VC Turbo four-cylinder engine, which was a finalist for the 2019 Autoblog Tech of the Year award, will appear on the roster. All-wheel drive will certainly be available, and Infiniti may offer an entry-level variant with front-wheel drive. Infiniti will present the 2021 QX55 online Tuesday during an event that will star singer Aloe Blacc. It will stream the concert-unveiling cross on its various social media platforms starting at 8:55 p.m. Eastern time, 5:55 p.m. Pacific time. Built in Mexico, the model will arrive in American showrooms in early 2021 with a base price pegged above $40,000. What's next? The QX55 will stand out as the first model released under Infiniti's Nissan-Plus strategy, which was presented as a way to cut costs and boost profits by increasing the number of components it shares with its parent company. However, leaning more heavily on Nissan will not dilute its image or its products, according to executives. Stylists are in the process of overhauling Infiniti's design language, and the brand's reboot will put a major emphasis on technology. Looking ahead, the QX will be followed by the next-generation QX60, which is tentatively due out in 2021 as a 2022 model, and by the company's first series-produced electric car. Related Video:

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.

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.
