Buick through the years

General Motors is attempting to make Buick more appealing to younger buyers with freshened up versions of the Regal midsize sports sedan and the LaCrosse large luxury car. GM unveiled the pair Tuesday ahead of the New York auto show.

Buick, once coveted for its understated elegance, used to be a dominant brand. In 1984, GM sold 942,000 Buicks in the United States, according to Ward’s AutoInfoBank. But many Buick buyers died, and younger people opted for SUVs and cooler European cars.

The 2013 Buick Encore debuted at the North American International Auto Show in Detroit on Jan. 10, 2012.

GM is giving the LaCrosse a more sculpted, modern look. It gets updated LED daytime running lamps and tail lights and a larger front grille. On the inside, it gets new, more supportive seats and a modernized center stack with fewer buttons than the current car.

The 2014 Buick Regal GS was introduced prior to the New York International Auto Show on March 26.

The Regal gets similar cosmetic changes on the outside. Inside, more supportive seats and a simpler dashboard and center console give it a sportier look. GM’s 2.4-liter four-cylinder ‘‘e-Assist’’ engine, with a small electric motor that helps boost gas mileage, becomes standard.
