F1-inspired, 563-horsepower Infiniti Q60 Project Black S details finally revealed

Despite being first revealed at the 2017 Geneva Motor Show, Infiniti has been quite coy concerning the details of its F1-inspired hybrid super coupe, the Q60 Black S. That ends at this year's Paris Motor Show, where the company has finally spilled specific information about the car. It's technologically fascinating, even if the on-paper performance doesn't sound all that shocking. Total power output of the concept, now called Q60 Project Black S, is 563 horsepower, with final torque figures yet to be announced. That power comes from a combination of the twin-turbocharged 3.0-liter V6 found in the Q60 Red Sport 400, along with a trio of motor-generator units that have similar functionality as those found in the Renault Sport F1 car's KERS (Kinetic Energy Recovery System). One large one is connected to the rear axle and generates electricity under deceleration like most hybrids, and it can deliver 160 horsepower under acceleration. The other two motor-generators are coupled to the turbochargers. They generate power under acceleration as the turbines spin. They also act as an electrical anti-lag system, spinning up the turbines when hitting the throttle again after it has been closed in order to provide maximum boost immediately. Power for and from these motor-generators is stored in a 4.4-kWh lithium-ion battery pack. All the powertrain's power goes through a seven-speed automatic transmission to the rear wheels via a mechanical limited-slip differential. The company claims it can hit 62 mph in under 4 seconds. One of the advantages of this powertrain is that electricity is generated both on acceleration and deceleration, which helps maintain battery charge so the motor assistance can be used more of the time. How aggressive the car is with the electrical boost is determined by which mode the vehicle is in, Road, Quali (for qualifying), or Race. Road is the most conservative, whereas Quali is the most aggressive. The reason for this is that if you're qualifying, you have to go the fastest you can in a short amount of time. A digital simulation of the car running a lap in Quali mode at Circuit de Catalunya estimated it would use 15 percent of the battery charge. That means it could do a little over six laps in that mode and maintain full use of its electrical assists. Race mode conserves battery life more, since you'll want that power over the course of the race. A downside to the Project Black S hybrid system is that it's really heavy.

2017 Infiniti Q30 First Drive

Audi and BMW have owned the premium C-segment for almost a decade now thanks to the A3 and the 1 Series (and 2 Series). Benz's A-Class has become less of a retiree's option and has spawned a popular (if not particularly good) sedan (the CLA) and a crossover (GLA). Down in the lower-class decks, machinery from Subaru is punching well above its weight, while Volkswagen's Golf owns the market in Europe. This all left perennial premium pretenders like Lexus and Infiniti with a problem: how to convince buyers their C-segment machinery was genuinely premium if they were based off a volume-selling donor body from Toyota or Nissan? Mercedes-Benz opened an odd window of opportunity for Infiniti. See, Benz's parent, Daimler, and Infiniti's motherships, Renault and Nissan, have had a technical alliance since 2010. A big technical alliance. So Infiniti was able to develop its hatch to sit atop the A-Class chassis, powertrain, and suspension architecture, though you'd barely know it by looking at the Infiniti from the outside. It has a style all its own, and you're not going to mistake a single angle on the Q30 for anything that comes out of Stuttgart. Nobody makes deeper cuts and curves into its metal than Infiniti. The Japanese brand claims that design is at its core, and whether you love or hate that design, it's hard to argue that point. The Q30 feels like a nicer, easier, more luxurious place than the A-Class on which its based. "Infiniti design is very three-dimensional on every panel. We want to give the sense and the feeling that every Infiniti has been made by an artisan, by hand, not by computer," the company's London-based design boss, Simon Cox, argued. Some will love it, some will hate it, and Infiniti can live with it either way. The point is that the brand is now on the field in a segment that is projected to keep growing at more than 9.4 percent globally, and it got there at a fraction of the normal cost of an all-new car, without having any easily identifiable cap tips to the Benz's far more conservative exterior design. The Benz bits are more obvious inside. Infiniti did such a good job of grafting its design ideas onto the interior hard points that it feels like a nicer, easier, more luxurious place than the A-Class, even if the Benz will be between eight and 10 percent more expensive in most markets. The dash top is clean, swooping, and stitched together beautifully.

Infiniti Q Inspiration Concept shows a future with variable compression

For weeks, Infiniti has been teasing the Q Inspiration Concept ahead of its official debut at the Detroit Auto Show. Details were absent, but the design was clean, swoopy athletic. Not seeing any tailpipes on the rear end, we hoped it could sport some kind of electrified powertrain, but surmised that Infiniti could take the opportunity to further showcase its variable compression turbocharged engine technology. Now, Inifniti has officially taken the wraps off its Q Inspiration Concept, and has indeed chosen to use the stunning show car to demonstrate "near future applications" of the potent yet efficient VC-Turbo tech. VC-Turbo made its production debut in the 2019 QX50 at the 2017 Los Angeles Auto Show. Here, in the Q Inspiration, VC-Turbo allows Infiniti designers to make the most of the packaging, taking advantage of the compact powertrain to increase the size of the cabin while maintaining the footprint of a mid-size car. Electric automakers like Fisker, Lucid Motors and the like have been doing something similar with electric powertrains, but Infiniti's VC-Turbo allows the company to do something similar with technology that is ready for primetime, while still bridging the gap to more efficient future powertrains. VC-Turbo, as we've learned earlier, allows the engine to change and optimize compression ratios on the fly, between 8:1 for high-performance situations, to 14:1 for maximum efficiency. Mounted to the exhaust manifold integrated in the cylinder heads of the four-cylinder engine is a single-scroll turbocharger. The system, says Infiniti, provides the torque and response of a hybrid or turbodiesel powertrain without sacrificing efficiency. In the Q Inspiration, the power is directed to four wheels via a front-biased all-wheel-drive drivetrain. The system can direct torque to the rear wheels individually as needed. As a design study, the Q Inspiration is a success. The proportions and lines are sleek and attractive, accentuated by the car's white paint. There's kind of a lot going on up front, with a large "double-arch" grille at the leading edge. Everything behind that, though, looks particularly harmonious. Its elongated cabin and coupe-like dimensions help provide efficiency while maximizing headroom for the four occupants. It's a car that stands up to close inspection, as attention to detail makes it more interesting the closer you scrutinize it, inside and out.
