A look inside Infiniti's variable-compression engine

We're sympathetic to anyone who had trouble understanding what's going on with Infiniti's new variable-compression engine. While we got a full tech briefing on the novel VC-Turbo back in August, the visual aids were lacking. The cutaway engine Infiniti brought to the Paris show fixes all of that. You can thank the little green and pink lines on the cutaway for making the whole idea a little more clear. Click through the gallery to see two lines – one green and one pink – that represent the different strokes allowing for different compression ratios. Remember, the compression ratio is the amount of volume in the cylinder on intake compared to the amount at the end of the compression stroke. Leave more room at the end and you lower that ratio. The length of the stroke doesn't change with this system, but where it sits along the cylinder does. Hence those two lines. The variable compression ratio allows this new turbocharged engine to maximize fuel economy when the turbo isn't needed by raising the compression ratio. It will see its first use in the next Infiniti QX50 crossover, previewed by the QX Sport Inspiration concept that's also on display in Paris, and has performance targets of 268 horsepower and 288 pound-feet of torque. After, it will migrate to other Infiniti and Nissan vehicles, with transverse front-drive-based applications first in line. Eventually, it's likely to completely replace Nissan's corporate 3.5-liter V6. We'll be poking around the engine a little more in Paris today to try and get some more info. For now, enjoy those cutaway images and those friendly little lines.

Infiniti Prototype 9 is a wonderfully beautiful EV grand prix car

Few automobiles are as elegantly beautiful as the open-wheel grand prix cars of the 1940s, '50s and '60s. The simple, slender shapes of these cars bear no extravagant flourishes or adornments. The purposeful design is what gave these cars their beauty, and it's these classic machines that inspired the new Infiniti Prototype 9. Teased earlier this week, this concept blends old and new, with classic lines hiding a modern all-electric powertrain. The Prototype 9 will make its full debut next week at the 2017 Pebble Beach Concours d'Elegance. Infiniti says the car was built around a simple idea: what would a 1940s Infiniti grand prix car look like? While the silver paint may be more German than Japanese, the design could easily be mistaken for an actual '40s grand prix car. Only the Infiniti-styled grille gives it away. Everything about it, from the thin bias-ply tires wrapped over center-locking wire wheels to the bulging screws around the driver's seat, is pitch perfect. Underneath that achingly long hood rests a prototype electric motor and battery from Nissan's Advanced Powertrain Department. The combo sends 148 horsepower and 236 pound-feet of torque straight to the rear wheels. That's good enough to send the svelte 1,962 lb car to 62 mph in just 5.5 seconds. Top speed is right at 106 mph. While speed may die off towards the top end, all that torque and a 43/57 front to rear weight distribution should make the Prototype 9 a riot on a small, tight circuit. There's only enough juice in the battery for about 20 minutes of flat-out racing. The handmade steel body rests on a steel ladder-frame chassis. The front suspension uses a leading-arm rigid axle with transverse leaf spring while the rear uses a De Dion axle, also with a transverse leaf spring. The Prototype 9 also uses old-school hydraulic rotary type dampers. There's no power steering and no brake booster for the four-wheel disc brakes. The car was designed and built by a number of different departments within Infiniti and Nissan. A simple sketch expanded as more and more designers and engineers wanted to have a hand in the project. The steel body panels were all shaped and hammered by hand. The bare cockpit is only adorned with a thin seat, three gauges, a few switches, a gear selector and the steering wheel. The gauges are set into a fixed aluminum hub in the center of the steering wheel.

2016 Infiniti QX60 gets a facelift, Hybrid still alive

The future of the Infiniti QX60 Hybrid looked grim a few months ago, when Nissan confirmed the Pathfinder Hybrid was being discontinued. After all, the QX60 and Pathfinder are nearly identical underneath their different bodies. But with this 2016 model year refresh, Infiniti confirms that its QX60 Hybrid will indeed carry on for the new year. It's the same hybrid system as before, combining a supercharged, 2.5-liter inline-four with an electric motor for a combined 250 horsepower and 243 pound-feet of torque. New liquid-filled active engine mounts are added for 2016 in an effort to reduce overall harshness. Non-hybrid models carry on with the naturally aspirated 3.5-liter V6, good for 265 hp and 248 lb-ft. Front-wheel drive is standard with both engines, and all-wheel drive is optional. That's the biggest news for the updated QX60. Everything else baked in to the refresh is pretty standard. Up front, there's a new fascia that better aligns the seven-passenger crossover with every other Infiniti product, and the taillights are slightly more stylized than before. It looks nice, but there's still no hiding those Nissan Pathfinder bones. Infiniti says new shock absorbers and springs will help improve ride quality, and steering effort is improved with a retuned, speed-sensitive electronic power assist system. Standard, Sport, Eco, and Snow modes will help you manage the power depending on the weather and your driving style. We don't know how much this will actually improve the QX60's ride, but we never really had any problems with the luxury crossover's relaxed dynamics, anyway. Look for the QX60 to officially debut at the 2016 Detroit Auto Show, following a reveal at a media event this week.
