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:

Watch Sebastian Vettel become first driver to lap Sochi GP circuit

In April of last year, Sebastian Vettel and David Coulthard drove the unpaved Sochi Formula One circuit in a pair of Infiniti M sedans, getting both muddy and airborne in the process. Now with tarmac laid down and fences put up, Vettel and Coulthard have gone back to the Black Sea vacation spot for another hot lap, this time in a Q50 Hybrid and without the need for mud flaps.
Sochi has earned the blessing of F1's race director, so now the next test will be the fans. With a healthy amount of wall-and-fencing along the straights, it has shades of Valencia for the viewer. We hope it will be much more exciting than its Spanish counterpart when racing happens on October 12. You'll find more videos below covering Infiniti's visits to the Sochi Autodrom, and a press release on the latest lap.

2022 Infiniti QX80 Interior Review | Refreshed, but still behind

You might assume the 2022 Infiniti QX80’s interior is filled with outdated technology from when it launched here about 10 years ago, but thatÂ’s not entirely true. You see, despite the rest of the car carrying over from the previous model year, the 2022 model year QX80 enjoys a refreshed interior. While this interior is updated, thereÂ’s no need to get overly excited. Nissan put the Armada through a mid-cycle refresh last year, and the QX80 essentially cribs all of its new bits directly from the Nissan. WeÂ’ve already tested the Armada, so we had an idea about what to expect when the refreshed QX80 landed at our doorstep. Thankfully, for InfinitiÂ’s sake, the ArmadaÂ’s new interior is nice enough that it's largely acceptable in the more luxurious QX80. It features a new, high-res touchscreen, flashy plastics, a simple layout and vital tech like a wireless phone charger, USB-C port and wireless Apple CarPlay — unfortunately, Android Auto remains a wired-only affair. The new look of this tall and vast center stack doesnÂ’t jive perfectly with the QX80Â’s flowy, rounded interior design, but thatÂ’s what you get when part of the interior is updated and the rest is left to carryover. Straight, strong lines dominate the center stack, complemented by rectangular vents. Meanwhile, rounded wood trim flows out of this brutalist center stack in a jarring manner that makes the interior look like two different designers worked on it separately, then had their work combined.  Functionally, the new parts of the interior are just fine. The new single touchscreen and its supporting user interface is a welcome update over the old dual-screen infotainment system that's still found in other Infinitis (it had only just received that system for 2020). Its large, width-oriented and mounted higher for easy viewing, plus the presence of supporting physical knobs and buttons make vital controls easy to use and adjust. The odd storage compartment in the dash houses the wireless phone charger, and the 12V outlet is hidden in there alongside it. We enjoyed the presence of a wireless phone charger, but it didnÂ’t charge our phones quickly, and the phoneÂ’s movement on the mat would sometimes cause it to stop charging altogether. Surprisingly, the QX80 is fitted with a camera rearview mirror, which was a nice surprise to see.
