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 QX50 confirmed for NY debut

It's been eight years now since Infiniti took the wraps off its smaller crossover. The model initially known as the EX was subsequently renamed the QX50 in the brand's broad nomenclature shakeup a couple of years ago, but now it's received what promises to be a comprehensive makeover to be revealed at the New York Auto Show next week. Though it hasn't given us any photos to go on (that's the current model pictured above), Infiniti has revealed that "the updated QX50 has a wheelbase increase of more than three inches, creating additional rear legroom and interior volume." We're also told to expect "new front and rear fascias, wheels, side sills, as well as a slightly higher ride stance." Nissan's rival to the likes of the BMW X3, Audi Q5, Volvo XC60 et al is offered Stateside with a 3.7-liter V6 driving the rear wheels or all four, but is offered overseas as well with a 3.0-liter turbodiesel. We'd expect the revised model to carry over the same engines, perhaps with some revisions, when it reaches showrooms this fall.

Infiniti takes QX60 on vacation for National Lampoon-inspired ad

Infiniti is packing up its version of the Wagon Queen Family Truckster for a new ad inspired by the American comedy classic National Lampoon's Vacation. Well, actually the 30-second spot replaces the green station wagon with a QX60, but the commercial does a great job of evoking the movie in a short time. The release timing is clearly perfect too given the remake hitting theaters on July 29 with Ed Helms and Christina Applegate. Infiniti's ad replicates one of the film's memorable scenes, but it replaces Chevy Chase behind the wheel of the Family Truckster and Christie Brinkley in a Ferrari 308. Instead, we get Ethan Embry in a QX60 and a blonde in a Lamborghini Gallardo droptop. The slight twist at the end really makes the commercial work, though. The ad starts airing nationally on July 9, but you can watch it streaming above now. Beyond just the surface-level homage, Infiniti gives the spot a slightly deeper connection to the Vacation series. In 1997's Vegas Vacation, Embry played Rusty. INFINITI DEBUTS NEW QX60 "VACATION" AD CAMPAIGN Infiniti recreates famous scene from "National Lampoon's Vacation" in 30-second commercial with 2015 QX60 Luxury Crossover Commercial stars Christie Brinkley and Ethan Embry Campaign includes extensions in digital and social media NASHVILLE, Tenn. – Infiniti has released a new campaign for the 2015 QX60, inspired by the 1983 classic "National Lampoon's Vacation" which coincides with the July 29 release of Warner Bros. Studio's remake. The campaign begins with a TV commercial starring the original movie's car-loving blonde bombshell and supermodel, Christie Brinkley, and puts a spin on the famous movie scene as the modern day family heads to Walley World. In the national spot titled "Vacation," Ethan Embry (who notably starred as Rusty in "Vegas Vacation") loads his family in the roomy 3-row QX60 and hits the road for Walley World. While on the road trip, Ethan looks in his side view mirror and sees an attractive blonde in a sports car fast approaching. As Ethan and the blonde keep up with each other on the highway, Christie Brinkley is revealed as his wife who catches this action and ends the scene with an ironic response: "Honey, a blonde in a convertible? Seriously?" The popular Infiniti QX60 continues to stand out in the premium crossover segment, excelling in the areas that luxury crossover buyers desire most – interior versatility, roominess, available safety, and available advanced hospitality features.
