2019 Infiniti QX60 and QX80 introduced with new Limited trim level

The 2019 Infiniti QX60 crossover and 2019 Infiniti QX80 full-size SUV debuted here at the New York Auto Show with new, more luxurious Limited trim levels. They include special wheels and even more luxurious interior touches. On the dark-grilled QX60 Limited, the custom wheels are 20 inches, and on the bigger QX80 they are 22. The half-leather seats on the QX60 are quilted, and the aniline color extends to the armrest and door cards as well. On the QX80, the "Limited" lettering stands out everywhere, from the center console to the seats, which are two-tone, leather and Alcantara. The QX80's dashboard wood trim is matte silver ash, and little trimline-specific details can be seen everywhere. The QX60's engine remains the standard specification 295-horsepower 3.5-liter V6, and the QX80's powerplant is the 5.6-liter V8 with 400 horsepower. Pricing hasn't yet been announced, but the QX60 Limited will be available this summer, and the QX80 Limited can be bought from summer onward. Related Video:

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:

Daimler and Nissan to build luxury cars at new plant in Mexico

A few years back, when Daimler was looking for a partner to spread the cost of development of small cars, it agreed to collaborate with Nissan on future products, such as vehicle platforms and drivetrains. The latest development in the collaboration concerns the assembly of small luxury cars for Infiniti and Mercedes-Benz at a Nissan plant in Mexico, two unnamed sources told Reuters.
The plant in question, Aguascalientes, is a $2 billion project that will open later this year next to an existing Nissan factory. The upcoming Infiniti Q30 four-door hatchback is expected to be built there, possibly alongside the Mercedes GLA-Class, which is one of several candidates Mercedes is considering to build at this facility, Reuters reports. The GLA will debut at the Frankfurt Motor Show this month, and initial production of the model will take place in Germany. The Q30 could follow a similar path, with assembly starting at Nissan's Sunderland plant in the UK, and then expanding to Aguascalientes later on.
The underlying platform of the Q30 and GLA, codenamed New Generation Compact Car (NGCC), was developed by Daimler. The Q30 would be the first Infiniti produced under the automakers' agreement. Last year, Nissan agreed to make engines that would find their way into Mercedes and Infiniti vehicles.
