Buick’s high-content compact sedan will gain a few new options for its sophomore year: An available cross-traffic alert system and a blind zone monitoring system.

According to a General Motors fleet guide posted online, the two items will be standard on the range-topping Verano with leather seats and they will be included in a Convenience Group on lower-spec Veranos. The Convenience Group also adds an automatic-dimming rearview mirror, a power driver’s seat base, heated exterior mirrors and rear parking sensors.

GM has not detailed specifications for the just-announced 2013 Verano Turbo, however.

Otherwise, the Buick sedan lineup mostly stands pat for 2013. Regals receive a few changes to their power steering system and a heated steering wheel is now standard on all but the range-topping GS (which has its own non-heated sport steering wheel). The base 2.4-liter gasoline engine has been dropped from the Regal lineup, which means that the automaker’s midsize sedan is now available only in mild hybrid eAssist or performance-oriented Regal Turbo variants.

The full-size LaCrosse is unchanged for what’s expected to be a short 2013 before a revised 2014 arrives, while the heavily updated 2013 Enclave crossover is set to go on sale late this year.

Pricing has not been announced for the 2013 Buick lineup.
