The Buick LaCrosse, redesigned in is helping to shed the image only AARP card-carrying purchase the tri-shield brand. The age of Buick buyers has fallen in the decade from the mid-70s to the 50s. To help juice up trend, and also appeal to new buyers (read green and Buick is offering a green the 2012 LaCrosse eAssist. It an EPA estimated 25 city/37 highway and 29

Those fuel economy are up from 19/30/23 for the 2011 with the same four-cylinder

Even though eAssist is in principle to the very mild (BAS) hybrid system used on the 2007 Saturn Vue Line and 2009 Chevrolet Hybrid, you won’t find the badge on the LaCrosse that those earlier vehicles. Motors is avoiding the H word time around in part the word has become synonymous the Toyota Prius, and also to previous complaints that mild form of hybrid doesn’t deserve the hybrid

A BAS system – sometimes called hybrid and micro hybrid – is a low-tech hybrid design. It is simply of an energy storage like a battery, and a beefed-up motor that can also act as a It essentially shuts off the engine the car stops, and quickly restarts it the brake pedal is lifted.

on design, it can provide some assist to the engine at speed, but not operation.

Even though the eAssist is coming at a time automakers are pushing toward degrees of electrification – and Honda for one is to engineer itself out of a mild approach that precludes in – this lower cost of hybrid technology deserves a in the hybrid family. After a jump in fuel economy 19/30 city/highway mpg to 25/37 mpg can a solid 30 percent gain in economy.

What Is eAssist?

The eAssist is quite descriptive. The system fuel mileage by “assisting” the engine, either by shutting the engine when the car comes to a or cutting off the fuel supply cruising or decelerating. When the car to a stop, the motor-generator unit the engine, bringing it to a smooth and also properly positions the for a smooth restart.

In like when in fuel shut-off the motor-generator continues spinning with the engine to provide and smooth take-off power the driver presses the accelerator.

new BAS design has noteworthy fuel gains compared to the earlier but neither comes close to mileage delivered by a “full operation like those in the Prius and Ford Fusion However, eAssist is more and performs better than the hybrid” stop-start systems in the Porsche’s 2011 Cayenne and models, and coming to nearly Ford model. Buick’s is closer in function and fuel to the “mild hybrid” systems in the Honda Insight and BMW ActiveHybrid 7.

been a lot of debate – mostly talk – about whether or not is a mild- or micro-hybrid, some the LaCrosse and the now defunct Honda Hybrid. The proof is in the pudding. The system doles out better mileage with its estimated in the LaCrosse versus 24/32 in the Accord.

Guess that eAssist at least as good as mild hybrid.

More Power, Less

eAssist has a 15-kw motor-generator replaces the original 5-kw in the Vue and Malibu. It is mounted on the engine in of the alternator, providing both assist and battery charging via a new system connected to the engine’s A 115V air-cooled lithium-ion pack is a significant upgrade the old 10 kw nickel-metal hydride battery The new batteries bolster the engine approximately 11 kw (15 horsepower) of electric assist during heavy and 15 kW of regenerative braking power.

compares with only 2 kw of assist and 5 kw of regenerative power on the setup.

Under the LaCrosse the new eAssist teams up with a 2.4-liter direct injection engine that generates 172 of torque. The previous design worked with a 2.4 -liter but horsepower was 172 for the Vue and 164 for the Malibu. Plus, the engine produces eight pounds-feet of torque thanks to direct fuel injection replaced the less-efficient multi-port type.

Additionally, the engine has an fuel shut-off during that provides added savings.

A new Hydra-Matic six-speed transmission replaces the conventional speed used previously. final-drive gearing keeps revs lower at highway boosting mpg. An auxiliary oil pump is added to the transmission, keeps it primed and the fluid when the engine shuts at a stop.

That keeps the ready to perform when the accelerates. The engine and transmission are to enable regenerative braking and charging during coasting and

More Fuel Economy

To eek out even more fuel mileage, engineers added a few to the LaCrosse not found on the Saturn Vue or Malibu. Aerodynamics are improved underbody panels that airflow and electronically controlled in the lower grille close at speeds to push more air the vehicle.

A smaller gas tank is used – gallons versus 18.4 – reduces the curb weight by the amount of fuel, but the eAssist range is still greater the 2011 model. The final is low-rolling resistant tires are optimized for performance and fuel

It’s the total package – the hybrid system and tweaks – produce the excellent fuel numbers.

Exterior And Interior

the covers came off the 2010 it was clear the exterior design was by the Riviera concept coupe at the 2007 Shanghai Auto Not as dramatic as the Riviera, the LaCrosse’s roofline contributes to an elegant, modern design. With honored details like waterfall grille, classic and signature “sweep spear” at the quarter panels, designers artfully crafted a look is tailored for the 21st century.

since the LaCrosse will a global vehicle, the vertical fascia complies with pedestrian safety regulations, that are expected to be adopted in the

Slide behind the steering and the late 1970s advertising “Wouldn’t you really rather a Buick?” comes to mind. in China, designers continued the exterior lines inside. The exudes the kind of quality and that buyers of luxury are used to.

Materials are rich everything fits perfectly and feels substantial and operates a smooth deliberateness.

Large and tachometer gauges are easy to at a glance. An ECO gauge below the aids the driver to optimize efficiency, while the driver-information has a hybrid diagram that electric power flow and the state of charge.

Officially classified as a mid-size dimensionally the LaCrosse is closer to a sedan. Up front, driver and are cosseted in firm seats are multi-hour comfortable with of leg and shoulder room.

As for high-tech gear, the LaCrosse offers all the gizmos and gadgets in a luxury automobile. New for 2012 is IntelliLink system as standard IntelliLink provides smart integration, allowing users to their mobile device the LaCrosse’s new 7- or 8-inch, full-color screen display radio.

On The Road

In the not-too-distant past, floaty ride was a throwback to times, and the handling and performance was far nearly all-modern sedans. the 2012 LaCrosse eAssist is a than capable performer and as well as any family sedan.

In daily life, our LaCrosse driver was rock-solid and as comfortable as pj’s. The seats are, splendid and the sedan managed our rugged urban terrain a dismissive sneer. Even the road hazards failed to kickback through the nicely steering system and the shocks the worst out of every bump and

The cabin was serenely quiet just a whisper of wind

We found the eAssist hybrid faultless to the point that a few miles it was easy to forgot it. When the engine restarts a stop sign pause, are no shudders or electric motor Response to throttle input is almost brisk, as torque from the motor joins the engine.

It may not be sport sedan but we found freeway merging and slower vehicles were in short order.

The LaCrosse came through with economy. After a week of on city streets and a couple of on Interstates, the odometer had logged 359 with an average of 30.7 which was more than the estimated 29 combined mpg. And in the final tally was affected by a 60 Interstate stint with the pegged mostly at 80 mph.

In an unconventional move, Buick has the LaCrosse eAssist as the base It starts at $29,995 and includes a driver’s seat, dual-zone climate control, a seven-speaker system, satellite radio, USB connection, the IntelliLink system and OnStar.

Stepping up to the Convenience at $30,465 not only adds start, power lumbar and dimming mirror, it also the choice of a 3.6-liter V6 rated at 303 for the same price. While we driven a V6 LaCrosse, and I usually more power, the V6’s economy of 17/27/21 would me toward eAssist.

Comparing the LaCrosse eAssist to it is less than Lincoln’s MKZ starting at $34,755 and the Lexus HS with a base price of While both competitors better in-town fuel than the Buick – 41 mpg for the Lincoln and 35 mpg for the – the LaCrosse on the highway nudges the MKZ by 1 mpg and the HS by 3 mpg.

eAssist is another that hybrid technology – in all its of flavors – will become commonplace in the auto market. In Buick has recently introduced the Regal eAssist, and the all-new Malibu Eco with eAssist is now in dealer showrooms.

However the eAssist hybrid system is, it has fuel economy gains and emissions and, when with the Buick LaCrosse, no additional cost.
