GM to Reveal 2012 Buick Verano at NAIAS in Detroit

GM will reveal the new 2012 Buick Verano compact luxury sedan, the brand’s third new model in the past two years and first in the compact luxury segment, at the North American International Auto Show (NAIAS) next week in Detroit. Verano goes on sale in the fourth quarter of 2011.

An Ecotec 2.4L engine with dual-overhead camshafts, variable valve timing and E85 capability coupled with a Hydra-Matic 6T45 six-speed automatic powertrain combination is standard. It delivers an estimated 177 hp (132 kW) and 170 lb-ft torque (230 N·m), 0-60 mph performance of 8.0 seconds and an estimated 31 mpg (7.6 L/100km) on the highway, 22 mpg city (10.7 L/100km). A 2.0L turbo engine will be offered in the future.

Direct injection technology helps it produce more power with less fuel and lower emissions, including up to 25-percent reduced hydrocarbon emissions when compared with a multi-point fuel injection engine. Electric power steering and a more efficient transmission design help optimize fuel economy.

The front suspension uses decoupled MacPherson struts for better isolation, providing greater separation of extreme road conditions—large potholes, for example—from everyday driving conditions. At the rear, a technically advanced Watts Z-link design helps center the rear axle during cornering, which helps keep the Verano’s handling responses symmetrical on both left-hand and right-hand turns. The linkage’s capability to center the axle during cornering delivers a more-balanced driving experience because the rear suspension better follows the lead of the front suspension.

The Z-link design is also lighter and requires less space than a typical fully independent rear suspension. The lower weight contributes to Verano’s fuel economy, while the compact design enables more trunk space.

Steering inputs are executed by a fuel-saving electric power steering system, featuring a dual-pinion rack. Engineers tuned the speed-sensitive system to provide quick, direct reaction to steering actions and a strong on-center feel. The system has a ratio of 15.5:1 and requires only slightly more than two turns, lock to lock.
