2012 Buick LaCrosse with Standard eASSIST™ Fuel-Saving
Technology Delivers Small-Car Efficiency
eAssist light electrification system provides 20-percent increase in highway fuel
economy and 32-percent better city economy
Estimated 36 mpg highway and 25 mpg city for about $30,000 – with full-size
luxury comfort and amenities
On sale this summer
DETROIT – This summer, the 2012 Buick LaCrosse goes on sale, with the fuel-saving
eAssist™ system standard. Using a variety of technologies and exterior enhancements, it
delivers an estimated 36 mpg on the highway and 25 mpg in the city – a 20-percent
improvement in highway mileage and a 32-percent boost in city mileage over previous models.
LaCrosse’s fuel economy rivals – or exceeds – that of small cars like the MINI Cooper (28
city/36 hwy with automatic transmission) and Toyota Corolla (26 city/34 hwy with 1.8L and
automatic transmission), but does so in a full-size luxury package that comfortably seats five
adults. MSRP is $29,960 before an $860 destination charge.
“Given the uncertainty of today’s fuel prices, the LaCrosse with eAssist is a smart and timely
choice for customers who seek excellent fuel economy and want the roominess and features of
a full-size luxury sedan,” said Tony DiSalle, U.S. vice president, Buick marketing. “The winning
combination of advanced technology, no-compromise driving performance and luxurious style
and passenger comfort stand to make LaCrosse with eAssist a must-have sedan.”
The LaCrosse with eAssist not only rivals the fuel economy of small cars, it trumps the efficiency
of non-hybrid segment competitors and is on par with the more expensive hybrid models. The

The eAssist system is mated to a 2.4L Ecotec direct-injection four-cylinder engine and next-
generation six-speed automatic transmission. It uses power stored in an advanced, air-cooled
lithium-ion battery to provide needed electrical boost in various driving scenarios, optimizing
engine and transmission operation. An advanced 115V lithium-ion battery and latest-generation
15-kW motor-generator unit help increase fuel economy through:
Regenerative braking, which provides up to 15 kW of electricity to charge the battery
Providing up to 15 hp (11 kW) of electric power assistance during heavier acceleration
Automatic and smooth engine start-stop functionality when the vehicle is stopped
The use of electricity instead of gasoline when stopped
Aggressive fuel cut-off during deceleration down to zero mph for added fuel savings
Intelligent charge/discharge of the high-voltage battery.
The eAssist system captures up to 15kW of energy that would be normally lost during braking
and uses it to recharge the lithium-ion battery. The system also shuts down fuel delivery in
certain deceleration conditions, further improving fuel economy. While in fuel shut-off mode, the
motor-generator unit continues spinning along with the engine to provide immediate and smooth
take-off power when the driver presses on the accelerator. As the vehicle comes to a stop, the
engine’s start-stop function is active when the motor-generator unit brings the engine to a
smooth stop to position it properly for a smooth restart when the brake is released.
A hill-assist system captures brake pressure to help keep the vehicle stationary when eAssist’s
start-stop function is activated on a moderate or steep grade, allowing the driver to accelerate
more smoothly from a stop.
Buick LaCrosse with eAssist technology also features improved underbody aerodynamics and
tires optimized for performance and fuel economy, as well as active control of front-end airflow
that improves aerodynamics and engine warm-up. Electronically controlled shutters in the lower
grille close at higher speeds to push more air over the vehicle, which increases aerodynamic
efficiency to enhance fuel economy. All of these technologies increase the eAssist system’s
regenerative braking capability, while also improving the vehicle’s efficiency while driving.
An ECO gauge on the instrument panel continuously responds to driving behavior, allowing the
driver to drive with maximum efficiency.
LaCrosse luxury, quietness and personal technology
In the pursuit of greater fuel efficiency, the LaCrosse with eAssist gives up none of the driving
attributes, quietness or technology that have helped make this luxury sedan one of the fastest-
selling in the segment.
The driving experience is underpinned by a four-wheel independent suspension system,
including a four-link rear suspension that uses isolating mounts to minimize noise and vibration.
StabiliTrak electronic stability control system is standard, as is a variable-effort power steering
system, four-wheel disc brakes with four-channel ABS, electronic brake force distribution and
brake assist system.
Inside is a flowing, uninterrupted design theme that wraps around the instrument and door
panels. Attention to detail is evident throughout the interior, including the analog instrument
cluster, chrome offset by dark woodgrain accents, and contrasting stitching on the instrument
panel. Ice blue ambient lighting is used throughout the cabin, including the center console,
instrument panel and door handle pockets.
Buick’s signature QuietTuning – an engineering process to reduce, block and absorb interior
noise – provides a distraction-free passenger environment.
The contemporary atmosphere of the cabin is accented with available digital connectivity and
personal technologies including in-dash navigation with a 40-gig hard drive (10 gigs reserved for
music), Bluetooth, an auxiliary audio input and a USB port. Rear-seat passengers can enjoy an
available power rear-window sunshade and a DVD entertainment system with two display
screens integrated into the seatbacks.
Later in the year, LaCrosse with eAssist will come with standard Buick IntelliLink, which uses
Bluetooth or USB to connect the driver’s smartphone to a new eight-inch, high-resolution, full-
color touch screen display radio. IntelliLink expands on Buick’s current Bluetooth and USB
capabilities to allow smartphone control via voice activation and steering wheel-mounted
controls. It also enables streaming stereo audio from the phone through services like
PANDORA® Internet radio and Stitcher SmartRadio®.
Most importantly, Buick IntelliLink enables seamless integration of stowed portable devices with
each vehicle’s infotainment system, allowing drivers to keep their hands on the wheel and eyes
on the road.
LaCrosse’s intelligent technologies also work to deliver a 360-degree field of vision behind the
steering wheel, for a greater feeling of comfort, security and safety. Side Blind Zone Alert
technology, which notifies the driver if a vehicle in adjacent lanes is traveling in the driver’s blind
spot, is available, as is a rearview camera system that features a display integrated into the
navigation system screen.
The technologies available on LaCrosse enhance standard safety features including front-, side-
and roof-mounted head-curtain air bags, and GM’s StabiliTrak stability- and traction-control
system. The safety and security of OnStar is also included for the first year of ownership.
LaCrosse with eAssist is manufactured at GM’s Fairfax Assembly facility in Kansas City, Kan.
