After twenty years of advancement, collecting some 200 patents along the method, Infiniti is the very first car manufacturer to move the vaunted concept of a variable-compression-ratio engine from the engineering laboratories and into production. The very first of lots of Infiniti cars that this 2.0-liter VC-Turbo engine will power is the brand new 2019 Infiniti QX50 compact crossover.
2019 Infiniti QX50 Review
Getting to the 2nd generation of what begun as the EX35 for the 2008 model year and after that was relabelled QX50 for 2014 has actually taken an extraordinarily long period of time compared to common automobile life process, and the aging model has actually been a sluggish seller, even as the crossover market has actually acquired momentum.
The QX50 changes from a front-engine, rear-drive platform that looked a little too hatchback-like– no doubt its kiss of death sales-wise– to a brand-new, all-steel, transverse front-engine, front-drive platform that’s significantly taller (by 4.2 inches) and larger (by 3.9 inches). In spite of this development, Infiniti states that the drag coefficient has actually been minimized by 6 percent on the brand-new model.
Dimensionally, the brand-new QX50 now falls right in line with the crowd of compact high-end crossovers, although, surprisingly, the wheelbase of the brand-new do not- call-it-a-hatchback is the exact same 110.2 inches as that of the initial EX35 (it ended up being the QX50 for 2014, and its wheelbase grew to 113.4 inches for 2016).

Nevertheless, the product packaging performances acquired from the switch to a transverse front-drive architecture plus the extra height and width must relate to completely competitive rear-seat area this time around, although Infiniti has yet to release interior measurements.
Freight volume for the brand-new model is 37 cubic feet with the second-row seats moved to their front-most position and 60 cubic feet with the seatbacks folded, which puts it at the big end of the class. Partly assisting the cargo-space cause is dropping an extra tire and changing to run-flat tires in 19- or 20-inch sizes.
Although we’re enthralled with the brand-new VC-Turbo inline-four engine, we will not rework all the information once again here. If you have not yet check out the engine tech, take a look at our extensive introduction from when the engine debuted at the Paris car program in 2015 and our report from briefly driving a model QX50 previously this month.
The fast summary is that a system of links and levers permits this port- and direct-injected engine to differ the stroke length of its 4 pistons by 1.2 millimeters to change the compression ratio from 8.0:1 to 14.0:1. When it’s making near to its peak output of 268 horse power and 280 lb-ft of torque and, state, running to a declared 6.3-second zero-to-60-mph time (that’s for the quicker, all-wheel-drive model), it will be running a lower compression ratio and greater turbo increase. However when peak power isn’t really required, it can ratchet up its compression ratio and, alike, its effectiveness.
2019 Infiniti QX50 Specs
Infiniti anticipates an EPA integrated fuel-economy score of 26 mpg for all-wheel-drive designs and 27 mpg for front-drivers, with the only transmission being a continually variable automated (CVT).
While those scores are at the top of the sector, they’re not a substantial leap from the 25-mpg score of an all-wheel-drive Audi Q5 or BMW X3, and it cannot match the Jaguar F-Pace diesel’s 29-mpg figure. As quickly as we can get one to check, we’ll provide you a complete report of how its real-world fuel economy accumulates.
The brand-new QX50 likewise includes ProPilot Assist, Infiniti’s driver-assist system that utilizes a forward-facing video camera and radar to check out and respond to surrounding traffic and lane markings.
Infiniti states this function is meant for highway driving, where it integrates control of velocity, braking, and guiding to keep the space to traffic ahead while keeping the QX50 focused in its lane.
2019 Infiniti QX50 Interior
Regardless of Infiniti’s claims of smoothness for this brand-new engine– which balance shafts are not needed– there’s an active upper engine install that works to counteract any undesirable engine vibes. The Bose audio system consists of noise-canceling and sound-enhancement performance that both work to make an excellent acoustic impression for the VC-Turbo.
In addition to all the procedures to keep it peaceful, the interior is dressed up with a leather-wrapped dash, quilted leather seats, and open-pore maple wood trim. The QX50 sticks to Infiniti’s multiple-screen infotainment setup, with 2 center touchscreens stacked on top of each other.
And amongst the numerous other details showed in the smaller sized screen tucked into the gauge cluster, there’s a readout revealing the happenings of the variable-compression engine.
Infiniti’s steer-by-wire system– that the business calls Direct Adaptive Steering which we’ve not discovered really reasonable in the Q50 sedan in spite of many modifications– ends up being a choice on the QX50, while a standard electrically helped rack-and-pinion setup is basic.
Although competitors amongst compact high-end crossovers has actually never ever been fiercer– and the brand-new QX50 will be up versus whatever from stalwarts such as the Lexus RX, the Audi Q5, and the BMW X3 to newbies consisting of the Jaguar F-Pace and the Alfa Romeo Stelvio– it appears that Infiniti has actually done the ideal things to offer its entry a much better chance at success this time around. 2019 Infiniti QX50
