Nissan’s chief powertrain engineer, says Infiniti’s VC-T engine is expected to deliver a combined city-highway EPA-rated fuel economy gain of 27 percent over the QX50s’s outgoing 3.7-liter V-6. The VC-T engine is rated at 268 hp and 288 pound-feet of torque. Kiga says the 2019 QX50 will reach 60 mph almost one second faster than its four-cylinder competitors.
The VC-T adds cost but is less expensive than a diesel engine. The VC-T engine is about 10 percent more expensive to produce than a regular 2.0-liter turbo four-cylinder engine.
The old engine had a combined city and highway mileage of 20 mpg. The new combined fuel economy should be around 26 mpg.

I like the opposed piston engine. The ICE isn’t quite dead yet, but exactly how many of these advanced variants will be deployed before EV’s take over the market remains to be seen.
