Buick Impala 2014

Although most consumers come home with midsize sedans, large sedans are worth considering, especially if you have a taller family in need of additional passenger space. One of our favorites in this segment is the 2014 Buick LaCrosse, whose highlights include neatly tailored styling, a well-trimmed cabin and a very smooth and quiet ride. This year, the LaCrosse receives freshened styling to the front and rear (a new hood, grille, lighting clusters, trunk lid and bumpers) and an updated interior. That interior is still quite elegant looking, with sweeping lines and rich surfaces highlighted by the generous use of LED accent lighting. For 2014, though, it now has a cleaner-looking center stack, highlighted by Buick's newest "IntelliLink" touchscreen interface. There are also some new safety features this year, including forward collision warning, lane departure warning and rear cross-traffic alert systems. Under the hood, little has changed for the 2014 LaCrosse. The base "eAssist" powertrain is a mild-hybrid setup (it can't propel itself solely on electric power) that allows the large Buick to earn an EPA combined fuel economy rating of 29 mpg. This version of the LaCrosse has some downsides -- it's kind of slow and noisy -- but it doesn't cost nearly as much as other fully dedicated hybrids like the Lexus ES 300h. Still, we think most shoppers will prefer the LaCrosse's powerful V6 engine, which better suits the character of the car and is available with all-wheel drive. Prospective Buick LaCrosse buyers should also be aware that this full-size sedan has an undersized trunk, a potential deal-breaker for some families. In addition, the IntelliLink touchscreen electronics interface looks slick but is often slow to respond to touch inputs, which can be bothersome. Plus, there are some great choices for a roomy, premium-oriented sedan this year, including the smartly designed Acura TL, the powerful Chrysler 300, the stylish Kia Cadenza and the refined Lexus ES 350 or ES 300h hybrid. You really can't go wrong with any of them. The 2014 Buick LaCrosse doesn't have a significant edge over any of these sedans, but it's a solid choice.

The 2014 Buick LaCrosse is offered with a choice of two engines. Standard on base and front-wheel-drive Leather trim levels is a mild hybrid powertrain that pairs a 2.4-liter four-cylinder engine with an 11-kilowatt electric motor and a lithium-ion battery pack. Combined peak output is 182 horsepower and 172 pound-feet of torque, and it's sent to the front wheels by way of a six-speed automatic transmission. In Edmunds track testing, a LaCrosse with this configuration ran the 0-60-mph dash in 9.2 seconds, a leisurely performance for this segment. Still, this powertrain is about efficiency, not speed. Aided by clever aerodynamic improvements like automatically controlled shutters behind the grille, it delivers an impressive EPA estimate of 29 mpg combined (25 city/36 highway). Optional for the two trim levels listed above and standard on everything else is a 3.6-liter V6 that cranks out 303 hp and 264 lb-ft of torque. The six-speed automatic and front-wheel drive are again standard, with all-wheel drive optional. At the track, a front-wheel-drive LaCrosse V6 sprinted to 60 mph in 6.8 seconds, which is about average for this segment. Fuel mileage estimates stand at 21 combined (18 city/28 highway) with front-wheel drive and 20 combined (17 city/26 highway) with all-wheel drive.

Standard safety features for the LaCrosse include antilock disc brakes, stability and traction control, front and rear seat side-impact airbags and side curtain airbags. Also standard is OnStar, which includes automatic crash notification, on-demand roadside assistance, remote door unlocking, stolen vehicle assistance and turn-by-turn navigation. All Buick LaCrosses except the base version have rear park assist and a rearview camera standard. Optional safety features include blind spot monitoring, lane change alerts (automatically warning you during indicated lane changes when another car is rapidly approaching you on either side from behind), rear cross-traffic alerts, a lane departure warning system, a forward collision warning system and automatic collision preparation. Many of these features tie into the optional vibrating driver seat, which vibrates to indicate the direction of a potential crash threat. In Edmunds brake testing, a LaCrosse with the 3.6-liter engine and 19-inch wheels came to a stop from 60 mph in 116 feet -- excellent for this segment. A LaCrosse with eAssist and 17-inch wheels turned in a similarly strong performance, stopping from 60 mph in just 115 feet.
