Earlier this year, we got wind of a patent filing from Infiniti for the name QX55. Set to arrive as a coupe version of the QX50, the QX55 will rival other SUV coupes like the BMW X4 and Mercedes-Benz GLC Coupe. We expect the QX55 to be loosely based on the Infiniti QX Inspiration Concept and act as a spiritual successor for the FX. Some of the outlets who have seen the QX55 in person say the design is amongst the prettiest in the SUV Coupe segment.

Infiniti will not reveal the QX55 until 2020 but says more details will arrive before then. The first teaser of the car only showed a single brushstroke but now the Japanese luxury brand has shown off a more intricate (but still blurry) teaser of its upcoming crossover coupe.

The front end should be broadly similar to the current QX50 while the rear will feature a coupe silhouette, like the old FX. Under the hood should be Infiniti's VC Turbo 2.0-liter inline-four rated at 268 horsepower and 280 lb-ft of torque going out through a continuously variable transmission. But even though the QX55 will feature a conventional gasoline engine (albeit with advanced variable compression technology), Infiniti has more advanced hybrid and electric drivetrains coming in the future.

Infiniti will adopt a "two powertrains, one platform" approach, where one platform will handle gasoline and electric drivetrains to lower cost and simplify development. The electric cars will feature a high-performance e-AWD (electric all-wheel-drive) system two electric motors - one in the front and one in the rear. These upcoming EVs should be pretty quick because Infiniti says they produce between 248 to 429 hp depending on the model. The quickest versions should hit 60 mph in around 4.5 seconds.

But Infiniti knowns not everyone is ready to embrace fully electric cars, so it will offer a stop-gap in the meantime. Along with the purely electric models, Infiniti will also sell EVs with a 1.5-liter three-cylinder gasoline generator with VC-Turbo variable compression ratio technology. The result will be an electrically driven car with the same convenience as a gas engine car.

"For three decades Infiniti has built a reputation for introducing powertrains that excite and empower drivers," comments Eric Rigaux, General Manager, Product Strategy & Planning for Infiniti Motor Company. "Our new gas-generated EV powertrain represents the next step into our electrified future, acting as a bridge to full electrification and setting the tone for our upcoming zero and ultra-low emission cars. However they are powered, our cars will offer thrilling yet serene electric performance and e-AWD systems which inspire driver confidence."
