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 names former BMW man Kruger to fill de Nysschen role

Today is turning into a big one for senior leadership changes in the automotive industry. Hot on the heels of Ferrari announcing the replacement of its chairman, Infiniti has announced the appointment of its new chief executive in Roland Krüger.
Serving until now as a senior vice president at BMW, Krüger joins Infiniti as its president as well as senior VP at parent company Nissan, reporting directly to Carlos Ghosn. Krüger had been with BMW since 1998, primarily as a regional director, having previously started his career as a designer for Mitsubishi and the Smart division at Daimler.
Krüger's appointment comes just over a week after the announcement that Infiniti's chairman Andy Palmer would be leaving for Aston Martin, and two months after the departure of outgoing Infiniti president Johan de Nysschen for Cadillac. The Japanese luxury automaker, headquartered in Hong Kong, has been in the meantime essentially operating by committee in the absence of a chief executive. The nomination of Krüger will surely bring a large measure of stability and direction as the company seeks to take a larger slice of the pie, in particular from German automakers like the one for which Krüger worked until now.

2023 Infiniti QX55 starts at $50,175, an increase of $2,650

Infiniti has added "more standard luxury amenities, driver-convenience features, and Infiniti Premium Care" to all grades of the 2023 QX55. The plusher digs come at a price, though. The entry-level Luxe and mid-level Essential trims have each gone up by $2,650, the 2023 Luxe costing $50,175 after the $1,025 destination charge, the 2023 Essential costing $55,275. The top Sensory trim has only been increased by $750, rising to $58,825. The dosh buys perforated leather upholstery, 4-way power lumbar adjustment for the driver's seat, a USB-C port for the back passengers, rear door handles with integrated LED welcome lighting, auto-folding heated outside mirrors with blind spot detection, and ProPILOT Assist across the board. Three-year standard maintenance program Infinity Premium Care is thrown in, too, providing routine inspections, oil changes and tire rotations for purchasers and lessees. Every variant also comes with wireless Apple CarPlay, but Android Auto still requires a cord. Moving to the Essential upgrades to adaptive LED headlights in a cube design with auto leveling, adds Traffic Sign Recognition to the ADAS suite, and extends feature content with items like climate controlled front seats, around-view monitor, and 3D building graphics for the navigation system. The QX55 Sensory picks up even nicer leather seating, four-way power lumbar adjustment for the front passenger, heated outboard seats in the second row, a heads-up display, and a motion-activated rear hatch. The powertrain holds steady with the 2.0-liter variable-compression four-cylinder making 268 horsepower and 280 pound-feet of torque, "shifting" through a continuously variable transmission and sending power to both axles. The 2023 QX55 can be configured at the Infiniti site now, arriving at dealerships sometime this summer.
