2018 Buick Enclave Avenir is a quiet beauty

Buick's Enclave three-row SUV is the first model to get the Avenir luxury treatment.

The Enclave Avenir has lane-keeping assist and lane-departure warning as standard.

Also standard are a 360-degree surround view camera system and a rear camera mirror, which can act as a traditional mirror or a digital display. We've seen this technology in GM's Cadillac brand and while it takes some getting used to, the digital display provides a much wider viewing angle.

The front fascia has a more upscale look in the Enclave Avenir.

The Avenir sub-brand includes details like a unique grille and 20-inch wheels.

Bifunctional LED projector headlamps grace the front of the Enclave Avenir.

An 8-inch touchscreen infotainment system includes Apple CarPlay and Android Auto as standard.

Interior colors are Avenir Chestnut and Ebony, with piping on the seats and contrasting stitching.
