2007 Buick LaCrosse Expert Review:New Car Test Drive
New Car Test Drive
A more athletic mid-size from Buick.
LaCrosse is the Buick of mid-size sedans. So, as you would expect, it's quiet, pleasant-mannered, and demands little of its driver or passengers. Its styling is sophisticated and modern, yet conservative. Inside is a rich, high-quality cabin with attractive woodgrain trim, nicely presented instruments and controls, and available leather seats with nice-looking gathered stitching.
What owners of recent Buicks might not expect is the way LaCrosse drives. Its steering is more precise, and it turns into corners crisply, with little body lean. In short, it handles quite impressively on winding mountain roads where it's capable of keeping up with any of the imported mid-size cars. Its V6 engines offer good power, growling under acceleration, but motoring along smoothly and quietly on the freeway. And of course its transmission works flawlessly.
Electronic features make the well-equipped LaCrosse a safe, all-weather family car with nice conveniences. Among them: a remote starting system that will work from up to 500 feet away, great on cold winter mornings; OnStar, which will dispatch emergency crews to your precise location if you have a wreck and don't respond to operators' calls; XM Satellite Radio to pick up Fox News, CNN, ESPN, or your favorite music; and StabiliTrak, which can help keep you from skidding off a slippery road. ABS and side-curtain airbags come standard.
For 2007, Buick LaCrosse benefits from revised trim and equipment upgrades, including a standard tire-pressure monitor and available Turn-by-Turn navigation from OnStar. Otherwise, it's largely unchanged from 2006.
The '07 Buick LaCrosse comes in three models. The base CX and the more luxurious CXL are powered by Buick's veteran 3.8-liter overhead-valve V6, rated at 200 horsepower. The performance-oriented CXS comes instead with a 3.6-liter V6 with modern double overhead camshafts and variable valve timing; although slightly smaller in displacement, it develops 240 horsepower.
CX ($22,230) comes with cloth upholstery, manually operated air conditioning, tilt wheel, six-way power driver's seat, programmable power locks with remote keyless entry, power windows and mirrors, theater-style interior light dimming, leather-wrapped shift knob, and a six-speaker AM/FM/CD sound system. All models also come standard with OnStar hardware and a one-year subscription to OnStar service. For '07, a tire-pressure monitor has been added to the standard-equipment list as well.
CXL ($24,645), features leather upholstery, dual-zone automatic climate control, a leather-wrapped tilt-and-telescope steering wheel, power lumbar adjustment for the driver's seat, a split-folding rear bench seat, driver information center, and content theft alarm.
CXS ($26,860) comes with thicker anti-roll bars front and rear, and 17-inch wheels and tires to go with the more powerful V6. CXS also boasts additional touches like driving lights under the front bumper.
Five- or six-passenger seating is available. Front bucket seats with a center console and leather-wrapped floor shifter come standard, but a six-passenger option for the CX and CXL is available that moves the shifter to the steering column and substitutes a 40/20/40-split bench seat whose center cushion flips over to become a mini-console.
A Comfort and Convenience Package ($690) for CX adds a remote vehicle starter, multi-language driver information center, dual-zone automatic air conditioning, a theft-deterrent system, steering wheel-mounted audio controls, tilt and telescope steering column, visor-mounted illuminated vanity mirrors and a cargo net.
A Driver Confidence Package for the CXL ($1,250) and CXS ($1,150) adds steering wheel-mounted audio controls, universal transmitter, electrochromic inside rearview mirror, dual heated and power-operated outside rearview mirrors, six-way power adjustable front passenger seat, Ultrasonic Rear Parking Assist, rear passenger interior reading lamps, and tilt-and-telescoping steering column.
Other options include nine-speaker stereo with MP3 capability ($545) or six-disc CD changer ($695); digital audio with XM Satellite Radio ($199) that includes a one-year subscription; power sunroof ($900); heated front seats, now available with cloth or leather ($295); power adjustable passenger's seat ($350); 17-inch chrome wheels ($650-750); remote starting ($190); and an engine block heater ($50).
Safety features on all 2007 Buick LaCrosse models include anti-lock brakes (ABS), traction control, a tire-pressure monitor, and side-curtain airbags, along with the required front airbags. Optional safety features include park assist and StabiliTrak electronic stability control.
The '07 LaCrosse is unmistakably a Buick, with its trademark vertical-bar waterfall grille, long nose, long slopes and simple body curves. A tiny third side window behind the C-pillar adds some visual interest, while at the rear, a discernible dent in the decklid ties the taillamps together and recalls the more adventurous surface development that characterized Buicks of the early 1960s. A single, slender chrome spear decorates the doors. XM Satellite Radio shares a single antenna with the standard OnStar system.
CX models can be identified by a grained, graphite-color finish on the rocker panels underneath the doors, while this panel is body color on CXL and CXS. Otherwise, the base CX has almost no decoration at all, beyond the bolt-on faux alloy covers for its 16-inch steel wheels.
Construction quality looks good. Body, door, and fender gaps on the LaCrosse are all noticeably smaller than on the previous Regal and Century models. And LaCrosse's headlamps are said to be 35-percent brighter.
To improve crash safety and reduce noise, Buick used generous amounts of expensive, high-strength steel, including steel reinforcements in the rocker panels, high-strength steel door beams, and a double-thick Quiet Steel floor pan and firewall. There's also an interlocking door latch system, a magnesium cross beam behind the instrument panel, another cross beam behind the rear seats, and structural foam in the front fenders.
The cabin is roomy and comfortable and exudes a general look of quality. The standard front bucket seats, clad in leather in the CXL and CXS, feature a new type of stitching, and newly developed silk-impregnated vinyl on the seat side panels emulates the look and feel of leather.
A six-seat option trades the front bucket seats for a bench seat and column shifter. The seat has a flip-and-fold center back cushion that can be converted into a spacious center console/armrest with a large storage bin and dual cup holders.
Rear-seat legroom is generous, thanks to a relatively long wheelbase of 110.5 inches. We found that a 6-foot, 4-inch passenger can sit behind a 6-foot, 4-inch driver with plenty of room to spare.
Interior quality and appearance are enhanced by reducing the number of individual trim pieces, which makes everything fit better and gives the cabin a richer, higher-grade look. Each of the three round instrument dials is wringed in chrome and set into a deeply tunneled instrument panel. Instrument graphics have been revised for '07, with red pointers and a more no-nonsense look; and the traditional Buick tri-shield emblem has been added to the steering wheel center. It's all very nicely presented, and relatively sporty looking.
The center stack is finished a mica-flecked flat black, with a trip computer and driver information system that's easy to put through its menu. However, the information panel is so glossy that it's hard to read in early morning or late afternoon light. The entire dashboard is decorated with a very good imitation woodgrain, which has been upgraded to a new Harvest Burl pattern for '07.
Buick uses its Quiet Tuning program to reduce, tune out, absorb, cover up and mask noise sources all through the car. Quiet Tuning uses specially engineered parts and adds sound insulation in the engine, on the firewall, under the toeboard, inside the wheel wells and in the roof. Buick's Quiet Tuning has made LaCrosse one of the quietest cars in the class.
Optional features upgrade this car to a cut above, making for a truly complete, safe, all-weather family car. Among them are a remote starting system that will work from up to 500 feet away; OnStar; XM Satellite Radio; and StabiliTrak. If we were ordering a LaCrosse, we would add all of these excellent systems.
The Buick LaCrosse CXS handles quite well, far better than you might guess, and it responds quite well to hard driving. The chassis is nicely tuned and balanced. This is no mushmobile. Both of the available V6 engines have been tuned to give a nice, healthy growl on full throttle, but disappear into the background in high-gear cruising.
The standard 3.8-liter engine that comes on the CX and CXL is smooth and quiet and is rated 30 miles per gallon on the highway. It's a gutsy V6 that generates strong torque, meaning you get good acceleration performance without having to rev it up much. This is an older cast-iron V6, but it's been thoroughly upgraded internally to reduce mechanical noise and features electronic throttle control. It's rated at 200 horsepower at 5200 rpm, and 230 pound-feet of torque at 4000.
The newer 3.6-liter V6 that comes on the CXS revs more freely and produces more power despite its smaller size: 240 horsepower at 6000 rpm. Its torque curve is also flatter, peaking with 225 pound-feet at 2000 rpm, but delivering 90 percent of that peak between 1500 and 6000 rpm. What that means is that you've always got good, strong power on tap in any situation. Mash the gas pedal and she goes. A thoroughly modern engine, the 3.6-liter features all-aluminum construction, double overhead camshafts, four valves per cylinder with continuously variable valve timing, and electronic throttle control.
All three LaCrosse models come with a four-speed automatic transmission. It works flawlessly.
As mentioned, the LaCrosse handles quite well. The steering is precise, really biting into the pavement when you want to turn. LaCrosse has terrific body roll control, meaning it's not bouncing and yawing around when pushed harder on rural roads. The suspension used in the CX and CXL is about 20 percent stiffer than in the old Regal or Century, with larger stabilizer bars, so the LaCrosse handles better than those cars.
Compared to the CX and CXL, the sportier CXS steers through a quicker ratio (13.3:1 vs. 15.3:1), featuring GM's electronic Magnasteer (rather than hydraulic) assistance. It also rides on stiffer anti-roll bars both front (32 mm vs. 30) and rear (19.4 mm vs. 17).
We found the CXS more responsive on winding roads in Northern Michigan. We later pushed one hard on some tight, bumpy canyon roads outside Los Angeles and found it handled quite well there, also. The grip from the tires is tenacious. Even when squealing around curves, the CXS maintained good composure, not losing its poise the way older American sedans tended to do. It offered good transient response, meaning it could change directions quickly in hard left-right-left maneuvers. The quicker steering ratio enhances the good steering feel and turn-in power we noted in the other Lacrosse models, CXS models with optional StabiliTrak feature GM's even more sophisticated Magnasteer II power steering.
For the most part, the LaCrosse rides smoothly, though we admit being a little disappointed in the ride quality on L.A.'s Interstate 405. It's a bumpy section of one of the busiest freeways in the world that really tests a smooth ride. Here, the LaCrosse suffered some vibration and the ride quality wasn't as smooth as we think a Buick should be. This is perhaps a trade-off of the responsive handling.
Three different traction control systems are offered: CX and CXL versions use a speed-based setup that cuts off fuel to reduce engine torque. This helps eliminate front wheelspin when accelerating on slippery surfaces, providing more stable control. The CXS comes with GM's full-range electronic traction control, which also selectively applies the brakes at one or more wheels as needed to restore traction.
StabiliTrak includes a traction-control function and also improves driver control during emergency or evasive maneuvers. We highly recommend ordering the optional StabiliTrak because it can help you avoid an ac.
Buick's long tradition of fine sedans is well-served and continued by the LaCrosse. It's a quiet car that impressed us with its steering precision and handling crispness. The interior has been given extra attention and that has paid off handsomely.
