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 prices renamed 2014 QX50 and QX80 crossovers

Earlier this week, Infiniti revealed the pricing for its two midsize crossovers, but now it has announced the pricing for its renamed bookend utility vehicles, the compact QX50 crossover and the fullsize QX80 SUV. Those looking for a smaller luxury crossover will be glad to learn that the 2014 QX50 now starts at $34,400* (a price drop of $2,500 compared to the 2013 EX), while pricing for the 2014 QX80 will remain the same as the 2013 QX56, starting at $61,350* (*prices do not include $995 for destination).
In terms of packaging, the QX50 will carry over unchanged, but the QX80 gets a new Backup Collision Intervention system as a part of its optional Technology Package. All of Infiniti's 2014 QX utility vehicles are on sale now, but for more details about the QX50 and QX80, scroll down for the official press release.

2020 Infiniti Edition 30 models priced

The 2020 model year marks the 30th anniversary of Infiniti, and as announced back in August, the brand is rolling out specially tweaked Edition 30 models across the bulk of its lineup. We now have more details and pricing for the commemorative editions, which are available on the Q50 sedan, Q60 coupe, QX50 compact crossover, QX60 mid-size crossover, and QX80 full-size SUV. The Q50 Edition 30 sedan's starting price is $43,700 with rear-wheel drive and $45,700 is all-wheel drive. The Q50 Edition 30 is priced between the Luxe and Sport trim levels, but its equipment is closer to that of the Sport. Although it's $4,800 cheaper than the Sport, the Edition 30 adds full-speed adaptive cruise control, but it uses the smaller brake rotors of the Luxe trim and it skips the Sport's adaptive damping. Unique Edition 30 elements include dark-chrome 19-inch wheels and exterior trim, black mirror caps, and a black mesh grille. The Q60 Edition 30 coupe is offered as a $4,200 package for the Luxe trim level. Added to the $45,500 base price of the rear-wheel-drive Luxe coupe, and you get a starting price of $49,700 for the Edition 30. All-wheel drive is another $2,000. Exterior enhancements mirror those of the Q50 Edition 30. The Q60 Edition 30 package also adds navigation, an around-view monitor, power-adjustable steering column, memory settings, rear auto-braking, adaptive cruise control, heated seats and steering wheel, and a few lesser items. The QX50 Edition 30 compact crossover builds on the mid-level Essential trim level. It's sold as a package for $1,200 and includes adaptive cruise control, blind-spot intervention, lane-depature prevention, and adaptive front lighting, plus 20-inch dark-finish wheels, dark-chrome exterior accents, a body-color rear diffuser, and a black headliner. For the range-topping QX80, the Edition 30 is a package that adds $3,500 to the Luxe (base) trim level. Besides the dark-chrome exterior trim and dark-finish 22-inch wheels, it includes a rear camera mirror, lane-departure prevention, adaptive cruise control, blind-spot intervention, and a black headliner. On Infiniti's most popular vehicle, the QX60, full details of the Edition 30 are not yet available, but we're told the model will start at $50,850. That represents a $4,700 premium over the Luxe trim level, and includes the content of the ProAssist package as well as the Edition 30 design enhancements.
