Buick's flagship sedan delivers what you'd expect. The new LaCrosse rides comfortably and features a well-trimmed and quiet cabin with a spacious rear seat. Paired with an eight-speed automatic, the smooth 3.6-liter V6 supplies plenty of power and a decent 24 mpg overall. The LaCrosse is one of the few offerings in the large-sedan class that is available with all-wheel drive. Handling is responsive but not sporty. The ride is cushy and absorbent, but we would skip the optional 20-inch tires, which transmit too much harshness to the passengers. Cabin access and visibility are compromised by the car's low stance. Most controls are easy to use, including the IntelliLink touch-screen infotainment system, but the unintuitive shifter proves maddening. Advanced electronic safety features are available only on high-end trims.
