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 teases the next generation QX80 SUV

Our latest teaser ahead of the New York Auto Show comes to us from Infiniti. The company didn't reveal anything more than a name, the QX80 Monograph, and the single picture seen above. However, we can determine a few things from this tidbit of information. First, Infiniti is teasing a vehicle that will represent the upcoming successor to the current QX80 SUV, albeit in concept form. Second, the SUV is going to see a fairly significant redesign. The headlights are now lined up with the top half of the grille rather than the bottom, and the tops of the fenders are higher. This provides a more aggressive, square-shouldered appearance. The lower vents and front spoiler look more aggressive, too. The SUV will be fully revealed on April 11 in time for the New York Auto Show, as will more details about the vehicle. At that point we should know if this is a completely new vehicle, or a substantial refresh of the current Nissan Patrol-based SUV. Related Video:

2014 Infiniti QX60 Hybrid

Infiniti launched its seven-passenger JX crossover for the 2013 model year with the automaker's familiar 3.5-liter V6 as standard equipment. For 2014, the model was renamed the QX60, and a new variant packing a gasoline-electric hybrid powertrain joined the lineup. (For those interested in the family lineage, the new arrival is a mechanical twin to the Nissan Pathfinder Hybrid, which we took for a Quick Spin last year).
Hidden beneath the hood of the QX60 Hybrid is a supercharged, 2.5-liter inline four-cylinder engine, rated at 230 horsepower and 243 pound-feet of torque. The combustion engine is supplemented by a 15-kilowatt electric motor, fed by a small lithium-ion battery back (hidden under the rear cargo floor), which adds 20 hp and 29 lb-ft of torque to the mix. Added up, Infiniti rates the total system power at 250 hp and 243 lb-ft - numbers that fall just short of its combustion sibling (the 3.5-liter V6 in the QX60 is rated at 265 horsepower and 248 pound-feet of torque). The only gearbox is a continuously variable transmission that drives either the front or all four wheels, depending on what the buyer specs.
The 2014 QX60 Hybrid AWD starts at $46,500 (the green model commands a $3,000 premium over the gas-only model). A long list of factory options such as Roof Rails ($495), Theater package ($1,700), Deluxe Technology package ($6,050), illuminated kick plates ($440) and a Hybrid Premium package ($4,600) bumped our as-tested price to a healthy $60,780, including $995 for destination.
