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 parts ways with Red Bull Racing

The partnership between Infiniti and Red Bull Racing is done. The team announced that it will no longer run under branding from the luxury automaker and will drop the Infiniti name from its own. The shift is effective at the end of this year. Infiniti signed on as a sponsor of the Formula One team back in 2011 when Red Bull was at the height of its dominance and on the path to the second of four consecutive world championships. Two seasons later it stepped up to naming rights, with the team officially rebranded as Infiniti Red Bull Racing. But while the cars ran under motivation from the automaker's ally Renault, they stopped short of rebranding the engines as Infiniti's, leaving it in the unusual situation of being a title sponsor of (but not directly involved in) an F1 racing team. For next season, Red Bull will continue running the Renault power unit, albeit rebranded under the TAG Heuer name. In the process, the team will no longer have any branding from the French automaker or any of its associated brands. Meanwhile sister-team Toro Rosso is switching from Renault to Ferrari power for next season, while Lotus is prone to switch back to Renault engines and ownership. The French automaker also recently canceled its support of the feeder series known until now as Formula Renault 3.5. Infiniti has carried out only limited racing programs in its quarter-century history. Aside from the Red Bull partnership, it directly sponsored Sebastian Vettel up until his departure for Ferrari. The company also supplied IndyCar engines in the late 1990s, then sponsored the Indy Lights series for a few years. It recently helped a privateer team prepare a Q50 for the British Touring Car Championship, but otherwise hasn't had any top-tier factory racing programs to speak of. That makes it one of the few Renault Nissan Alliance brands (and Japanese automakers) not to actively participate in motorsports. Related Video:

2020 Infiniti QX80 refreshes its cabin, adds tech and safety features

After performing a nip-tuck on the Infiniti QX80's sheetmetal for the 2018 model year, designers have massaged the QX80's interior for 2020. The driver's cluster keeps the analog gauges but loses the previous, low-res digital information screen. A new seven-inch TFT display is tucked between the dials. The infotainment spread on the center console finally gets the real estate it deserves, an eight-inch touchscreen up top with a seven-inch touchscreen below. Android Auto and Apple CarPlay are standard, as is Wi-Fi hotspot capability. Above all that, the rear view mirror went to school to become the Smart Rear View Mirror, meaning it can operate as the usual reflective surface or as a monitor for the rear-mounted camera feed. It's an option on the entry Luxe trim, standard on the top Limited trim. New standard safety features on both variants include backup collision intervention, blind-spot warning, lane departure warning, and rear door alert. On the aesthetic side, a new Charcoal Burl wood interior trim with gradation joins two new premium exterior colors, Coulis Red and Mineral Black. For more intense ornamentation, Infiniti offers the Edition 30 package for 2020 with a black mesh grille and dark chrome trim on the front fascia, black mirror caps, more dark chrome on the tailgate finisher, stainless steel kickplates, and 22-inch dark wheels with black center caps. It's possible engineers will turn to the engine for the next update cycle. For now, the QX80 continues with the 5.6-liter V8 putting out 400 horsepower and 413 pound-feet of torque, shifting through a seven-speed automatic. It's a thirsty lump, the first version of the VK56VD engine hitting the market in the Infiniti Q45 of 2002, but QX80 fuel economy is in the ballpark with other full-sized, V8 competition.  As has happened for the past few years, prices go up for both trims. The Luxe starts at $66,750, a $1,250 bump over 2019. The destination charge also rose by $100 to $1,395; adding that brings the total to a $68,145. Opting for 4WD on the Luxe remains a $3,100 option. MSRP on the Limited goes up by $1,250 as well, totaling $92,845 after destination. Related Video:
