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:

2018 Infiniti QX80 Drivers' Notes Review | Big, brash and big

When it comes to body-on-frame, full-size SUVs, it seems every automaker has the same strategy. Offer one version as a more affordable, workman-like model, and another one as the plush luxury model. Ford has the Expedition and the Navigator, Toyota has the Land Cruiser and the LX 570, GM has the Tahoe and the Escalade. Over at Nissan, the pairing is the Nissan Aramada and the Infiniti QX80. We recently reviewed the Nissan version, and we just had a turn in the Infiniti. So how did the Infiniti fare against its proletarian twin? Read on to find out. Associate Editor Joel Stocksdale: So here's the thing about the Infiniti QX80: It's literally just a flashier Nissan Armada. As I sat down to write my thoughts, I took a second look at what I wrote about the Nissan-badged version, and I realized almost everything on my mind I already covered. The thing is enormous. Walking up to it, it seems like it might be an inch taller than me (5'11"). It's pretty wide, too, and the width is consistent all the way up. But it is still easy to drive with light steering and very good visibility. The 5.6-liter V8 sounds lovely and seems well-matched to the truck, and the transmission shifts smoothly and picks gears well. The real problem I see is that my feelings about the QX80's interior are nearly identical to those of the Armada. They're virtually identical, especially when comparing the higher trim Armadas. They have the same infotainment, the same buttons. There are a lot of buttons, too, scattered seemingly haphazardly and are difficult to use, especially with the very dated infotainment system. The dash design and shape of the wood are the same, and so is the steering wheel. The only things I could tell were really different were the shift knob, the gauge faces and the quilted leather seats. And Nissan offers a version of the latter on the Armada Platinum Reserve. I'm dwelling on this a bit because the Infiniti QX80 is not cheap. The four-wheel-drive one we had here in Michigan had a base price of $68,845. That's a few thousand more than the aforementioned Armada Platinum Reserve, and I don't see how the Infiniti is worth that extra money. It seems all you're getting is a flashier exterior, especially with the $2,800 22-inch wheels, and a more prestigious badge. I need more than chrome and badges to spend so much money. My recommendation is just buy an Armada.

Infiniti Q30 goes full monty before Frankfurt

Infiniti is finally tearing off the camouflage and showing the world what the Q30 luxury hatchback actually looks like. Set to make a full debut Frankfurt Motor Show on September 15, the five-door marks the entry of the Japanese premium brand into the compact hatch ranks. The company's designers did a fantastic job of bringing the major elements from 2013's concept to the street, though. Like the earlier design, the production Q30 wears Infiniti's rounded rectangle grille and a chrome strip along the edge of the hood. The headlights are also left squinting from the concept. The only major change to the front end is an adjustment to the lower air dam to make it a little more realistic for production. Sadly, Infiniti is only providing this single front three-quarters perspective on the upcoming five-door for now, but check out the C-pillar in the background to spot the similarly pointed design there, as well. The changes are actually more noticeable when comparing the Q30 with its platform-mate, the QX30 compact crossover concept. The hatchback noticeably softens many of the CUVs swoopy lines to be a bit more mainstream. This is especially true along the front where the big air intakes from the QX are made significantly smaller. Production of the Q30 is slated to start in Sunderland, England, by the end of the year. They should actually arrive in showrooms there before the calendar runs out. Still, we're looking forward to Frankfurt for a more complete view of Infiniti's little luxury hatchback.
