2019 Infiniti QX50 Essential Drivers' Notes Review | Variable impressions

The 2019 Infiniti QX50 is the brand’s second smallest crossover, and itÂ’s fully redesigned for the 2019 model year. Infiniti decided to use the stylish QX50 as a technology flagship, specifically using it to debut its variable-compression engine technology. It has since been shared with Nissan in the new Altima, but Infiniti got the new 2.0-liter turbocharged four-cylinder first. It makes a solid 268 horsepower and 280 pound-feet of torque, numbers that are very similar to the outgoing QX50Â’s 3.7-liter V6. However, the 2019 QX50 with all-wheel drive (as our tester is equipped) nets you 26 mpg combined to the old carÂ’s 20 mpg combined rating. Infiniti pairs the new engine with its continuously-variable transmission. We happen to be testing the absolute pinnacle of what a QX50 can be: the “Essential” trim level. The base QX50 Pure starts at $37,645, whereas ours towers up to $59,085. That steep price is thanks to the addition of several high-dollar packages, including the $7,500 Sensory Package. This is the price youÂ’ll pay to get the ultra-luxe interior that we happened to fall in love with. The Autograph Package added $2,000, netting us white leather with the blue suede accents. Then the ProActive ($2,000) and ProAssist ($550) packages provide all the advanced driver assistance features like ProPilot Assist. Take note that the frustrating steer-by-wire (DAS) system is also included in the ProActive Package. Assistant Editor, Zac Palmer: When fully optioned as our QX50 Essential tester is, this interior can mix it up with the best in the business. You may have to sell a kidney to afford it, but the quilted white semi-aniline leather, soft blue suede and light maple (real) wood is going to make it all worthwhile. Infiniti certainly nailed it on the materials, but the interior design and styling flourishes are executed just as successfully. There's a simplicity to the flatness and gently curving horizontal lines that feels so graceful and luxurious. I feel that I'd never tire of the cream, brown and blue color combination, though that light-colored leather means I'd forever be trying extra hard to keep it clean. All of this interior loveliness was almost enough to make me forget about this crossover's interior tech shortcomings. Infiniti hasn't integrated Apple CarPlay or Android Auto, and the stock infotainment system isn't nearly polished enough to warrant such an omission.

2013 Infiniti IPL G Convertible

Infiniti rolled out the IPL version of its G37 Convertible at the Los Angeles Auto Show more than a year ago. The Infiniti Performance Line treatment logically mirrors that of the IPL G Coupe, meaning it receives both cosmetic and mechanical tweaks designed to raise the pulse of driving enthusiasts. Aside from the overstated aerodynamic styling components and huge exhaust tips, the cabin features special leather upholstery, aluminum trim and IPL badging to distinguish it from lesser siblings. Under the hood, the 3.7-liter V6 (VQ37VHR) has been recalibrated to deliver 343 horsepower - 18 more than the standard coupe - and 273 pound-feet of torque. The suspension has been upgraded with firmer spring and stabilizer bar rates, multi-piston sport brakes are fitted and 19-inch graphite-finish wheels wrapped with summer rubber are bolted on. There are only two exterior color choices (Moonlight White and Malbec Black) and two upholstery choices (Stone and IPL-exclusive Monaco Red). Everything sounds marvelous until someone reveals its as-tested $62,415 window sticker.
DRIVING NOTES
The three-section steel roof raises and lowers in a leisurely manner - give it about 30 seconds each way. While it is marvel to watch, the operation seems clunky, not fluid. Buttoned up, with all four windows closed, the cabin is comfortable. Wind noise is minimal and the front buckets coddle passengers in all the right places. While tight, those of smaller stature will find the two rear seats tolerable for short journeys (my kids never complained). Outward visibility is also very good for a convertible - no impeding B-pillar.

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:
