Infiniti keeps us on our toes for Q50 Eau Rouge

If you've been watching the evolving rapprochement between Infiniti and Red Bull Racing, and have wondered what the point was if the Japanese automaker didn't capitalize on its expensive collaboration with the world-champion Formula One team, then Infiniti may finally have the answer come the Detroit Auto Show next month.
That's where Nissan's premium division is set to unveil the Q50 Eau Rouge concept, a show car set to showcase its F1 involvement in the form of a jazzed-up sports sedan. We still don't have much to go on in terms of what the concept car will actually entail beyond a body kit, but Infiniti has launched a dedicated website for the reveal and with it, this teaser video. It still doesn't tell us much, but it's a cool animation just the same, so check it out below.

Infiniti's variable compression engine in the 2019 QX50 is the first of its kind

The world's first variable compression ratio engine is here, in a production car. That car is the 2019 Infiniti QX50, debuting this week at the Los Angeles Auto Show. The midsize crossover has seen a refresh that has brought it an all-new platform together with new driver assist features, but it's the engine that's the centerpiece here. Nearly everything is continuously variable under the hood of the QX50 – not only the new shift-by-wire XTRONIC CVT. The new VC-Turbo gasoline engine is able to change its compression ratio from 8:1 to 14:1, or anything in between depending of the driving situation; whether there is need for top-end power or turbodiesel-like torque from low revs, or optimized fuel economy. The pistons' reach is continuously adjusted by an electric "Harmonic Drive" motor, which controls a multi-link system, affecting the top-dead-center of the pistons and changing the compression. The engine can also switch between efficiency-maximizing Atkinson cycle and regular combustion cycle, on the go – and there's both multipoint injection and gasoline direct injection employed. The result is 268 horsepower at 5,600 rpm and 280 pound-feet of torque at 4,400 rpm; good figures for a 2.0-liter four-cylinder gasoline engine with a single-scroll turbocharger. Infiniti says that the FWD version's fuel economy of 27 miles per gallon combined is 35-percent better than the previous-generation V6 engine; in AWD guise, it reaches 26 mpg, which is a 30-percent improvement. The new engine is pretty much all-aluminum, but the vaguely magical-sounding "transformative multi-link components" behind the variable compression system are made from high-carbon steel alloy. The engine's multi-link system also enables it to do away with any balancing shafts, and Infiniti compares its smoothness to a V6 rather than a regular four-cylinder. In addition to the aforementioned tech, the VC-Turbo engine has the world's first active engine mount vibration damping system to smoothen its operation even further. Related Video:

Infiniti QX60 AWD vs. Mazda CX-9 Signature

In certain ZIP codes around Dallas, Chevy's Suburban remains the Official SUV of Texas, but Infiniti's QX60 could be the Official Crossover. The Pathfinder-based three-row is everywhere. And while its popularity is based on transporting kids and their stuff, the QX60 is a more urban Suburban. Mazda's CX-9 is not as ubiquitous as the QX60 in McMansion driveways, but it has been making inroads into the near-luxury segment with its near-luxury spec. The CX-9's second generation has obviously upscale intent, in the sheetmetal and throughout the top-line Signature interior. And the prices of these two cars are surprisingly close. INFINITI QX60 AWD: The sheetmetal differentiating Infiniti's QX60 from its volume-oriented Nissan donor is attractive. The changes are subtle, and in profile the Pathfinder and Infiniti are almost identical, but the eye is drawn to the differences in the grille and D-pillar. The Infiniti has a luxury vibe with a more athletic stance. The QX60's interior surfaces seem upscale, but if you want wood it will cost you. In "building our own" and opting for graphite leather with maple trim, the wood requires another $12,000(!) of mandatory packages, including Infiniti's Premium and Premium Plus packages ($1,800 and $2,900, respectively) and $7,300 of Deluxe Tech. So, wood? We wouldn't. But if you do, know the QX60 won't match the larger QX80 in presence or passion, but it is certainly something beyond a rebadged Pathfinder. For you and your passengers, there is 156 cubic feet of interior room; with the second and third rows folded, you can accommodate 76 cubic feet of cargo. Like in most crossovers, that third row is best used by young kids, but taking six adults to lunch won't require too much gymnastics – or chiropractics. On the road, the QX60 is known more for comfort than composure; this isn't an old Buick, but neither is it a BMW. Nissan's 3.5 liter V6 produces generous power (295 horsepower and 270 pound-feet of torque), but it's transmitted to either the front wheels or all wheels via a CVT (continuously variable transmission). Nissan has tried to mitigate the quirkiness, but it's a CVT all the same. At a well-equipped base of $44,000, we like the QX60. But start adding options, and you can approach $60,000, which is real money even in the better ZIP codes. MAZDA CX-9 SIGNATURE: This, ladies and gentlemen, is dramatic. Mazda has absolutely nailed it. Using Mazda's KODO design language on a large platform could have gone wrong.
