2017 Buick LaCrosse is a sleek traditional sedan

The new LaCrosse is at once familiar looking and all-new. This is a good thing.

We don't see many sedans of this scale on the road anymore.

The LaCrosse is nearly 200 inches long, and rides atop a wheelbase of 114.4 inches.

The new wingform grille adapted from Buick's very successful recent concept cars looks good hear.

Dramatic taillights emphasize the design's width.

From this rear three-quarter vantage, you can see how the Sweep Spear side contouring gives the rear of the car substantial haunches.

Silver paint shows off the sheetmetal's contours well.

Here's your first look at the LaCrosse's very comfy interior.

The dashboard is laden with soft-touch materials and real stitching.

The 3.6-liter V-6 may share its displacement with last year's engine, but it's all new.

20-inch wheels are an option, 18-inch units are standard.

HID headlamps are standard, with some upper-trim models receiving a dynamic-cornering function.

Larger 20-inch wheels are paired with a more sophisticated front suspension geometry.

Headlamps are nicely detailed.

Buick's trademark VentiPorts are here, albeit meekly. They're non-functional and they could probably disappear without really affecting the design.
