• The Buick LaCrosse is a sophisticated mid-size sedan, seating five passengers in comfort while providing confident handling and a smooth ride.

2012 LaCrosse V6 models get more power than last year, thanks to a retooled version of Buick's 3.6-liter V6 that now makes 303 hp and 264 lb-ft of torque. It comes with a 6-speed automatic transmission. The 2012 LaCrosse looks as fresh as the all-new 2012 Buick Verano compact sedan does. The LaCrosse eAssist model compares with the Lincoln MKZ hybrid and the underwhelming Lexus HS 250h sedan. The navigation system features a big display and is easy to operate. The suspension eats up bumps and ruts in the road, unlike the previous-generation LaCrosse, but it isn't overly floaty.

Redesigned for the 2010 model year, the Buick LaCrosse midsize sedan still looks contemporary, elegant and refined. A regenerative braking system recharges the battery when the car is coasting or when the driver hits the brakes. The electric motor adds about 15 horsepower to the gas engine's 182 horsepower and 172 foot-pounds of torque. The result is a fluid exterior design that flows around the vehicle. Sweeping lines, soft-touch materials and genuine stitching define the dash and doors.

New for 2012 is Buick LaCrosse eAssist, which uses a 2.4-liter four-cylinder gasoline engine paired with a small electric motor.

Smooth and quiet, the Buick LaCrosse is a nice luxury sedan. In addition, a Start/Stop feature shuts off the engine at intersections, then it seamlessly restarts the engine as the electric motor thrusts you forward. It's conservative but not conventional.

Other changes for 2012 include a revised trim level structure.

Still, the 2012 Buick LaCrosse has stiff competition including the lauded Hyundai Genesis sedan, the luxurious Lexus ES 350, and the newly refreshed Acura TL.

With its well executed design, quality materials and solid driving dynamics, the 2012 Buick LaCrosse is a good choice for those looking for a comfortable midsize sedan with several combinations of available features. All of this makes the LaCrosse a compelling choice among premium midsize sedans. Buick heritage cues are evident, such as the waterfall front grille and the signature portholes. Engineers worked to give the LaCrosse a stiff structure for a quiet cabin and a smooth ride. Fuel economy numbers remain virtually unchanged at 17 mpg City, 27 mpg Highway, 21 mpg Combined on front-wheel drive models and 16 mpg City, 26 mpg Highway, 20 mpg Combined with all-wheel drive. Now in the third year of its current design, the 2012 Buick LaCrosse offers attractive styling, quality materials, a comfortable ride and a bevy of available electronic gadgets. The 2012 LaCrosse comes standard with a four-cylinder engine that uses a small electric motor for improved fuel economy, a system called eAssist. You could call eAssist a mild hybrid.

The 2012 LaCrosse eAssist offers a significant improvement in fuel economy with an EPA rating of 25 mpg City, 36 mpg Highway, 29 mpg Combined.

The interior has a finely detailed, high-quality character. Aerodynamic improvements including automatic shutters in the front grille of the LaCrosse eAssist further highway fuel economy. Roomy and comfortable, it's larger than the Lexus ES and Lincoln MKZ yet it's easy to maneuver around town. A V6 engine is available with optional all-wheel drive. All-wheel drive is available. Braking feels confident and able. Chrome and wood trim are used tastefully, and the materials in the headliner and upper parts of the cabin have a premium look and feel. It's an on-demand system designed for startup acceleration, long uphill grades, highway passing maneuvers, and freeway on-ramps. The V6 comes on Premium and Touring trim models and is also paired with a 6-speed automatic.

We found the LaCrosse comfortable yet still responsive. It's smooth but feels taut and stable, with no floating about or wandering. Out on the highway, it glides along quietly. With all this technology going on in the background, the LaCrosse eAssist drives pretty much like a regular luxury car.

Cars with the eAssist powertrain have enhanced aerodynamic touches to improve fuel economy, including automatic shutters in the grille that close at road speeds over 30 mph, a front spoiler, and flat panels underneath the car to minimize chassis drag. The Buick LaCrosse exterior was designed in North America, the chassis was developed in Germany, and the interior was designed in China. It's distinctly original, and yet, the car remains recognizable as a Buick. Standard Michelin P235/50R-17 low-rolling-resistance tires further increase efficiency.

There is a notably high belt line, and the wheels are snugly enclosed at the outer ends of the body. It's no surprise, then, that the LaCrosse has a definite international look to it. Viewed from the side, the profile is not unlike that of a sport-compact coupe, but the LaCrosse is a roomy car, and bigger than it looks.

All LaCrosse models come with a 6-speed automatic transmission. Acceleration is a bit brisker because of the added torque of the electric motor, and that extra power is evident in passing maneuvers. The V6 is smoother, quieter and more responsive than the four-cylinder with eAssist. We've driven the Buick LaCrosse with the V6 and with the four-cylinder engine with eAssist.

The four-wheel disc brakes are impressive both in terms of pedal effort and overall feel on the LaCrosse V6 models.

This latest-generation LaCrosse rides smoothly. As with a German car, small bumps are heard and felt but are damped and controlled. It handles big bumps well, not pogoing after big dips. We were impressed with its intelligent, smooth shifting.

Driving and living with the LaCrosse eAssist is very much the same as with a regular car.

The 3.6-liter V6 allows for easy loafing about, even at low revs. Cruising is quiet with the motor/generator in cruise mode. Our preference was to put it in Drive and let the automatic take its cues from our throttle input. The V6 models use hydraulically assisted, variable-ratio steering, and we found it pleasingly quick and precise and surprisingly neutral considering the front-wheel-drive layout. Acceleration performance is adequate for merging into fast traffic or overtaking, but it lacks the verve and brightness of the V6. But power is quickly on tap when the throttle is pinned to the floor. The car feels very stable and goes exactly where the driver intends. The seamless restart is impressive given the roughness of the Start/Stop feature on the new BMW 3 Series. We found the option to shift manually is hampered by the location of the shifter, which is relatively far back in the center console.

Braking with eAssist feels slightly different because the system starts to regenerate electricity slightly before it starts to slow the car, but it's not bothersome.

The cabin of the LaCrosse is pleasantly quiet. The eAssist models come with an electric steering system with the same fast variable ratios; it's neither twitchy nor slow. The system stops the engine at intersections to save gas and reduce emissions, then seamlessly restarts it when the driver presses down on the accelerator. The V6 is rated at 303 horsepower and 264 pound-feet of torque, much bigger numbers than those produced by the four-cylinder. The variable assist programming gave us a firm, controlled feeling at speed and very light effort when parking. Although the 2012 Buick LaCrosse with eAssist is rated by the EPA at 29 mpg Combined, we were only able to average around 25 mpg during a four-day road trip with mostly freeway driving. Buick engineers have damped, cancelled, and isolated road and wind noise using materials like acoustic glass, liquid and fabric sound deadeners, engineered seals and tuned mounting systems. They offer gentle stopping at the very top of the pedal, making it possible to bleed in braking gently, for smooth, progressive stops. The engine makes a pleasantly balanced, muted mechanical whir when revved, but otherwise runs very quietly. The four-cylinder engine is noisier than the V6 when accelerating.

Leather upholstery is of good quality, though not buttery soft. Guidelines give the driver a good idea of the path the car will take when backing and turning.

Storage space is slightly less than average for a car of this class. Attractive wood and contrast stitching accents doors, dash and the shifter assembly. Maps are crisp and easy to read. Models with eAssist offer a mere 11 cubic feet to make room for the lithium-ion battery pack. The 2012 Buick LaCrosse offers 13.3 cubic feet of trunk space in upper trim levels.

Front seats are comfortable and have a wide range of adjustment, though, like most modern cars, more petite drivers might find themselves swallowed up in the broad, long cushions.

Front side visibility is somewhat marred by a combination of large A pillars and large, angular sideview mirrors, but models equipped with the optional blind spot warning system will help to alleviate fears.

Heated seats warm up quickly, and the dual-zone climate control reaches the ideal temperature with haste.

Rear seats offer ample legroom, but headroom is limited, making the back seat an option only for those shorter than six feet tall. A steep rake in the rear window makes rear visibility adequate but not generous. Cloth comes standard, but we haven't seen it. It also displays the outside temperature, which seems a questionable use for a head-up display. This system uses a silent light that displays on the sideview mirror, without the annoying beeps and chimes that other manufacturers employ. Buttons can be programmed to allow the driver to select among favorite AM, FM, and satellite radio stations by pressing just one button. Like other Buick models, the LaCrosse brings fresh air into the cabin at the last selected temperature, even when the climate control is turned off, so driver and passenger must occasionally turn the system back on to make adjustments. Styled air vents on either side of the navigation screen, which mimic the design of early Buicks, have a vintage feel and an ample range of adjustment. Although there are several buttons on the center stack, they are logically placed, with clearly separate areas for climate control, audio and navigation functions. The optional head-up display projects the speed on the windshield, which is handy.

The instrument cluster looks premium, although it's tough to see the exact speed using the analog speedometer; it's best to use the electronic version on the driver information display. Design is thoughtful and materials are of good quality inside the 2012 Buick LaCrosse. LaCrosse uses a traditional key, a welcome relief from today's keyless start systems that can create unexpected problems. The audio system is easy to operate. By comparison, the Lexus ES offers 14.8 cubic feet and the Lincoln MKZ boasts 16.5 cubic feet. Cubby storage is sufficient with a center console, though the sliding, ribbed cover for it looks like it could collect dust and crumbs. The rearview camera provides the driver with an excellent view of what's behind the car whenever the transmission is shifted into Reverse. The side mirrors are big and provide a good view rearward.

The navigation system features a massive 8-inch display that's bright and easy to read and decipher. It's a valuable safety feature because it can help the driver spot a child when moving in reverse. The head-up display, or HUD, also shows compass heading and displays songs, which is handy.
