Infiniti will debut its QX50 midsize SUV concept at the North American International Auto Show in Detroit.

The vehicle will preview Infiniti’s ProPilot semi-autonomous system. The ProPilot system acts as a “co-pilot,” which empowers the driver rather than replacing them. The system will navigate stop-and-go highway traffic, or keep track of surrounding vehicles, Infiniti said.

The concept is “an evolution of the 2016 QX Sport Inspiration,” according to an announcement. The concept showcases the Nissan Motor Co. luxury brand’s knack for sleek designs in the SUV platform.

“With the unveiling of the QX Sport Inspiration at the 2016 Beijing Auto Show, we showed the future of Infiniti QX models,” said Roland Krueger, president of Infiniti, in a news release. “The new QX50 Concept evolves this concept further and shows how Infiniti could develop its future presence in the fastest-growing vehicle segment globally.”

Infiniti will also exhibit its new Variable Compression Turbo engine technology in the concept vehicle at the Detroit auto show. The VC-Turbo engine has the power of a 2-liter turbo engine, and the torque and efficiency of an advanced diesel powertrain, the company says.

The production-ready engine “represents a compelling alternative to diesel powertrains,” according to Infiniti.
