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:

2023 Infiniti Q50 gets small price bump and Premium Care

The Infiniti Q50 sedan continues for 2023 without the support of its coupe sibling, the Q60. There are just three small changes on the way, one being the addition of Infiniti Premium Care. Expanded to every Infiniti sold or leased in the U.S., Premium Care is a regular maintenance program for items like oil and filter changes, tire rotations, and inspections for up to three years. The second change is a higher price, the Q50 starting at $43,725 including the $1,075 destination fee, a $610 increase over 2022. MSRPs for the three trims next year and differences from 2022 are: Q50 Luxe: $43,725 ($610) Q50 Sensory: $49,425 ($400) Q50 Red Sport 400: $57,575 ($600) The last change is the availability of a Saddle Brown interior, which used to require stepping up to the Sensory. Rear-wheel drive is the standard layout, all-wheel drive can be optioned to any trim for $2,000. The twin-turbo 3.0-liter V6 hold steady at 300 horsepower and 295 pound-feet of torque for the Luxe and Sensory, or 400 hp and 350 lb-ft for the Red Sport 400, shifting through a seven-speed automatic no matter the output. It's possible there are more people who want to know where the Q50 is going than want to buy the car. The brand sold 8,482 Q50s in the first half of 2021, but just 3,717 units in the first half of this year. The high point came in 2016 when 44,007 units moved that year, two years after the sedan went on sale, and the model heading into 2023 has been hanging on for 10 years. The brand talked about a potential new electrified platform for the sedan in 2018, but come 2021 Nikkei Asia reported parent company Nissan would be ending development of all sedans in Japan excepting the Skyline. The Q50 seems like it's doing circles in a product cul-de-sac, knowing there's no point in revamping the current generation or developing a new one. But the car on sale is just bringing down values; unlike much of the rest of the market, there's real money to be saved on a one- or two-year-old Q50. Perhaps when the electric revolution has some power behind it in 2027 or 2028, we could see a return to the hot Infiniti sedans of yore.   

Six luxury-car features I'm ashamed to admit I love

A hot compress felt wonderful on my sore back. The methodical kneading of my shoulder blades loosened the knots that formed over several hours of driving. The Swedish-style pulses firing into my lumbar region released more tension.
I wasn't getting a much-needed massage following a recent road trip. I was getting it during the road trip.
I grew up riding in the back seat of a 1976 Chevy Nova. But once you use these lux features, it's easy to go soft.
