Thanks
largely to Chinese customers, GM sold nearly 1 million units of the
last generation Buick LaCrosse since 2009. That guarantees the car a
second generation. The new LaCrosse does not deviate from its
established formula: a near-luxury large sedan targeting at the same
audiences as Lexus ES instead of the sportier European competitors. It
keeps the transverse-engine, front-wheel drive format, but now you can
specify HiPer strut front suspension or even a torque-vectoring 4WD
system. It is certainly more versatile than before.
Buick did some very stylish concept cars in recent years. The LaCrosse
follows them to adopt a sleek, coupe-like shape, but the end result is
not as convincing. Its nose looks handsome enough, but the gently
curving waistline and the heavy-handed crease line over rear fender
look all too familiar to Hyundai Azera. The round boot lid and
taillights look a bit cheap in the new world order where finer details
are appreciated. Despite the coupe-like roof line, the car doesn’t
look very athletic. You are aware of its FWD layout from its
cab-forward proportion.
While
the new car keeps its length and width unchanged, its roof is lowered
by 40 mm. This, in addition to the coupe-like curve, robs some
headroom, no matter front or back, so the new LaCrosse is not as roomy
as its exterior dimensions would lead you believe. Rear passengers
enjoy good legroom thanks to the wheelbase stretched to 2905 mm, but to
cope with the sloping roof it has to mount the rear bench low.
Moreover, the rear cushion is flat and soft, resulting in mediocre
seat comfort.
At the first glance, the interior design is fresh and quality seems
high. However, like so many Buicks, a closer inspection will find it is
built to cost. The wood trims and leather upholstery are not real
items, although they don’t feel too cheap. Some plastics on the center
console and dash are low rent and prone to scratch. That said, the
Buick
feels easily classier than the equivalent Kia or Hyundai by replacing
most plastic surfaces with leather and wood trims. The design is also
cleaner and more modern, while GM’s infotainment system is responsive
and easy to navigate. There are
plenty of storage space, including a bin located just under the
floating console on which an electronic gear shifter is mounted.
GM claims the new car loses 300 pounds (136 kg) compared with its
predecessor thanks to the use of high-strength steel, lighter sound
deadening materials and other weight saving measures in many
components. The base FWD model weighs 1632 kg, on a par with Lexus ES
and other Korean rivals. AWD and adaptive dampers add about 110 kg,
still lighter than the old FWD top model. This relieves the burden to
the 3.6-liter direct-injection V6. Like the applications on Cadillacs
and Camaro, the new LGW engine features
automatic stop-start and “active fuel management”, the latter turns the
engine into V4 under partial load to save fuel. Its output is
considerably enhanced from the old V6, now pumping out 310 hp
instead of 280 and 282 lbft of torque instead of 259. It also eclipses
its Japanese and Korean rivals, so performance should be a touch
stronger. Expect 0-60 mph to be achieved in the low 6-seconds range. GM
wisely skips a more powerful engine option as the LaCrosse chassis is
not good enough to take more. The shrinking market segment also kills
the need for another engine.
On the road, the V6 is satisfyingly willing and refined. Its cylinder
deactivation switchovers seamlessly, although auto stop-start is less
so. GM’s 8-speed automatic transmission is smooth and imperceptible,
although more demanding drivers will find it too civilized.
Despite
weight cut, the LaCrosse hasn’t sacrificed NVH. Laminated windscreen
and front side windows are standard, as are triple door seals. Active
noise cancellation audio is optional. The redesigned 5-link rear
suspension also helps smoothing and quietening ride. In fact, on the
road its refinement is massively
improved, now on a par with Lexus. Noise level is remarkably low. Ride
comfort is excellent on the base FWD model with softer suspension
setting and 18-inch wheels. Predictably, the flipside is mediocre body
control and a steering that is both light and numb. All too familiar to
old Buick owners.
Fortunately, the GM division now also takes care of “normal” drivers.
You can opt for a sportier package which includes torque-steer-reducing
HiPer strut front suspension (instead of conventional MacPherson
strut), continuous adaptive dampers, 20-inch wheels and wider tires.
Press the additional “Sport” button and the car’s handling is
transformed. While it is still no BMW, the body control
and steering effort are much improved. You can hustle the car into the
twisty with some fun, something you would not expect for a big Buick.
Do you really need the ultimate AWD option? Probably not. Although it
employs a Ford Focus RS-style twin-multiplate-clutch rear transfer unit
for torque vectoring, it is designed for lighter duties thus could be
easily overheated in prolonged use. After all, the LaCrosse is not a
sports sedan by any means. Comfort is still its major chord.
