Infiniti Prototype 10 concept to debut at Pebble Beach

Last year, Infiniti launched its gorgeous Prototype 9 concept at the Pebble Beach Concours d'Elegance. It was an open-wheel, retro-styled car inspired by Grand Prix racers of old. Just as important as its design, though, was its powertrain. It was all-electric. This year, at Pebble Beach, Infiniti will return with a new speedster concept called Prototype 10. It, too, will be electrified. Teased in the above image, the open-cockpit Prototype 10 will be another single-seater steeped in classic design, though with looks the automaker describes as "cool, clean and forward-looking," borrowing some cues from the Infiniti Q Inspiration concept we saw at the Detroit Auto Show earlier this year. Karim Habib, Infiniti's executive design director, describes Prototype 10: The Infiniti Prototype 10 echoes the layout and design of some of the most evocative car designs of all time, where power was celebrated through high-powered single-seat competition cars. Our new concept speaks of an electrified future, something which is reflected in its form and details. It is appropriate that we found inspiration in an optimistic bygone era in which cars were characterized by the simple love of driving. Still, Infiniti leaves out most of the details about the car. We're curious what kind of "electrified" powertrain Prototype 10 will use, but the company plans to electrify its whole lineup beginning in 2021. It's possible Infiniti could tease further images and information, but we'll likely have to wait for its official unveiling at Pebble Beach on Aug. 23, which is right around the corner. If the last two concepts are any indication, this one should be a stunner as well. Related Video: This content is hosted by a third party. To view it, please update your privacy preferences.

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.

2022 Infiniti QX60 pricing starts just under $48,000

Just a month after being revealed, the 2022 Infiniti QX60 has pricing. The base model starts at $47,875, which is $2,500 more than the outgoing model. The model line spans four trims, Pure, Luxe, Sensory and Autograph. Each one comes standard with front-wheel drive with all-wheel drive as an option. Adding all-wheel drive adds $2,000 for all trims except the Autograph, which costs $2,900 as it includes the tow package with a hitch, hitch wiring and transmission oil cooler. You can see the base prices for all trims below, and the crossover goes on sale this fall. Pure: $47,875 Luxe: $53,925 Sensory: $57,375 Autograph: $61,375 The QX60 comes pretty well equipped even at the base level. On the outside, it has 18-inch alloy wheels and LED headlights and taillights. Inside it has a 12.3-inch infotainment screen, nine-speaker sound system, power hatch, panoramic sunroof, leather first- and second-row seats, front seats with heat and power adjustment and three-zone climate control. Some of the safety features include front and rear automatic emergency braking, blind-spot warning and rear parking sensors. Moving up to Luxe adds 20-inch wheels and roof rails outside. Inside it gets a 12.3-inch instrument display panel, heated and cooled seats. Tech upgrades include navigation, ProPilot Assist highway and stop-and-go assistance, surround-view cameras, traffic sign recognition and remote start. Sensory focuses on the interior with massaging front seats, heated outboard second-row seats, power-folding third-row seats, wireless phone charging, motion-sensing power hatch, open-pore wood trim, ambient lighting and a Bose 17-speaker sound system. The top-rung Autograph has a number of exclusive upgrades. The exterior features a black roof and roof rails. The interior gets semi-aniline leather, captain's chairs in the second row with a removable center console, 10.8-inch head-up display, camera-display rearview mirror and adaptive headlights.
