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:

2022 Infiniti QX60 fully revealed with vastly improved design

After a "concept" was shown last September, the significantly redesigned 2022 Infiniti QX60 has finally been revealed. And inside and out, it's a huge design improvement. It has a more traditional SUV exterior, with a much more modern and luxurious-looking interior complete with an infotainment system from this decade. As expected, the production QX60 looks just like the concept, and that's good in our book. It has a boxier, more confident shape but still with the brand's signature curvy detailing. The new two-tone paint is only available on the top-level Autograph trim, though. Interestingly, the new QX60 has the same wheelbase as the crossover it replaces, though it's overall two inches shorter and about an inch taller. Perhaps not surprisingly, the QX60's interior doesn't seem to have changed in size much. Only cargo space has been announced, and while it has 1.4 cubic feet more space with the third row folded, space is down by between 0.4 and 1.4 cubic feet behind the first row and the third row respectively. Space wasn't really the QX60's interior weakness, though — that was in the extremely dated design. Fortunately, the new model tosses everything from the old one out the window. It now has a low, flowing dash that helps provide a more airy feeling. It has the en vogue full-width air vents. It's particularly fetching in Autograph trim as shown above with semi-aniline quilted leather and open-pore wood trim. The infotainment is updated and features a 12.3-inch touchscreen. It can be matched with an available 12.3-inch instrument screen and a 10.8-inch head-up display. Infiniti has added additional sound-deadening, too, and among the standard features are a panoramic sunroof, three-zone automatic climate control, eight-way power heated seats, wireless Apple CarPlay, wired Android Auto and seating for seven. The Autograph swaps the second-row bench for captain's chairs. Powering the new QX60 is a tried-and-true 3.5-liter V6 making the same 295 horsepower and 270 pound-feet of torque as before. But, like its cousin the Nissan Pathfinder, it's now connected to a nine-speed automatic transmission, which also bumped towing capacity up to 6,000 pounds. Front-wheel drive is standard with all-wheel drive available on all trim levels. Infiniti says the all-wheel-drive system has been reworked for faster engagement, and it's able to send up to half of the engine's power to the rear wheels.

Nissan recalls 226k vehicles over airbag inflators

Nissan and Infiniti are the latest automakers to issue recalls involving faulty airbag inflators from Takata. The Japanese automakers have announced campaigns covering about 226,326 units from seven models built in the early 2000s because they contain the bad part in the passenger-side, front airbag. The affected vehicles include the 2002-2004 Nissan Sentra, 2002-2003 Pathfinder and 2002-2003 Maxima, and it also covers the 2002-2003 Infiniti QX4, 2002-2003 I35, 2003 FX45 and 2003 FX35.
Like the other vehicles with the faulty inflators, it's possible for the part to rupture during airbag deployment and spray metal shrapnel at occupants. Nissan and Infiniti have even included vehicles with replacement airbags in this campaign because those parts also could have been defective. Both companies were also part of the earlier regional campaign to fix cars in high-humidity climates where the problem has been found to be the worst.
As is the usual response, Nissan and Infiniti will notify owners of the affected vehicles and will make the repair at no charge. According to the filing with the National Highway Traffic Safety Administration, these fixes will commence around August 11.
