2010 Buick LaCrosse - Click above for a high-res image gallery

General Motors has announced that its new 2010 Buick LaCrosse will be available with its fuel-sipping 2.4-liter Ecotec four-cylinder. Equipped with the direct injected engine and paired with the sedan's standard six-speed automatic, GM says the combination should deliver 30 mpg on the highway and 20 mpg in town.

It will be interesting to see if the 182 horsepower, 172 pound-foot of torque inline-four will be able to effectively motivate a car of the LaCrosse's size, but either way, plugging the capable engine in the Buick ought to give GM a unique selling point against V6-only competitors like the Lincoln MKZ.

Buick says it expects about 25% of LaCrosse buyers will check the four-cylinder box at purchase time. Check out the official press verbiage after the jump.

Buick To Add Fuel Efficient Ecotec 2.4L Four-Cylinder Engine To All-New 2010 Lacrosse

New Engine Joins Two V-6s for an All-Direct Injection Lineup

DETROIT – A fuel-efficient, direct injected Ecotec 2.4L four-cylinder engine will be the third engine offered in the 2010 Buick LaCrosse luxury sedan. Backed by a fuel-saving six-speed automatic transmission, the new powertrain combination is expected to deliver fuel economy of 30 mpg highway and 20 mpg city*– making LaCrosse one of the most fuel-efficient cars in its segment.

"Buick LaCrosse customers will have the fuel-efficient option of the Ecotec 2.4L direct injection engine, a four-cylinder that is not available by key competitors, such as the Lincoln MKZ and Acura TL," said Susan Docherty, Buick-Pontiac-GMC vice president. "Features such as a rear-seat entertainment system and remote starting are other technologies that are segment exclusives, contributing to LaCrosse's balanced package of design, performance and intelligent technology."

The Ecotec 2.4L four-cylinder joins the lineup later this year as the standard engine in the LaCrosse CX. Direct injection technology helps it deliver 182 horsepower (136 kW) and 172 lb-ft. of torque (233 Nm). Buick expects about 25 percent of customers will opt for 2.4L-equipped models.

The 2.4L's injection of fuel directly into the combustion chamber enables a higher compression ratio to increase efficiency and horsepower. That means more power is made with less fuel and lower emissions. In fact, cold-start emissions are reduced by up to 25 percent with direct injection. Engineers tuned the Ecotec 2.4L engine to deliver greater torque at lower rpm and build it smoothly toward its peak at 4,900 rpm, giving the Buick LaCrosse excellent performance in all driving conditions.

"Direct injection is a key component of GM's ongoing strategy to use advanced propulsion technology to help us deliver more fuel-efficient cars today and in the future," said Tom Stephens, vice chairman, Global Product Development. "GM is using multiple technology pathways to achieve increased efficiency and to diversify energy sources – and we're applying them where they make the most sense for customers when it comes to efficiency, performance and cost."

Every engine in the LaCrosse lineup is direct injected and matched with a fuel-saving six speed automatic transmission. Along with the Ecotec 2.4L, a new, direct injected 3.0L V-6 is offered and a larger-displacement, more powerful 3.6L V-6 is standard on the LaCrosse CXS model.

Quiet, low-maintenance performance

As with the 3.0L and 3.6L V-6 engines, the Ecotec 2.4L is designed to deliver exceptional quietness with low maintenance requirements and minimal environmental impact – including 100,000-mile service life ratings for the spark plugs and accessory drive belt. It is also equipped with GM's Oil Life system, which uses a sophisticated algorithm to determine when it's time for an oil change. The system calculates the oil life based on a variety of closely monitored variables, such as engine speed, temperature, load and others, allowing fewer oil changes over the life of the vehicle for a significantly reduced amount of used oil that must be recycled.

LaCrosse and Buick's renaissance

The 2010 Buick LaCrosse luxury sedan is the newest example of the globally influenced product renaissance at Buick. It offers all-wheel drive, a suite of advanced intelligent personal technologies and safety features, and great styling that blends heritage cues with modern design.

"The new LaCrosse builds on the success of Enclave as the next step in Buick's renaissance," said Docherty. "It will attract a whole new type of buyer to our dealerships, as Buick strengthens its position as one of GM's core brands."

General Motors Corp. (NYSE: GM), one of the world's largest automakers, was founded in 1908, and today manufactures cars and trucks in 34 countries. With its global headquarters in Detroit, GM employs 235,000 people in every major region of the world, and sells and services vehicles in some 140 countries.

      I find it strange with all the vehemence about the 4 cyl. option. If you only can drive a V6 then do so. Like someone said, other people might want the car with a lot of options, but they prefer a bit better gas mileage. A lot of these cars might get bought if gas prices go way up again. Toyota is sticking a 4 cyl. in their Highlander, a big SUV, just for that reason. If gas goes up again, many of the pricey vehicles will add 4 cylinders. Applaud GM for some forethought. The Big 3 have been criticized for having no fuel-saving options in their vehicles, and when they do, they are criticized for doing just that. I hope they bring the "Cruze" version of the Buick here to the States. I think it would do well.
      • 6 Years Ago
      When the '86 Taurus debuted, it blew people away with its driving dynamics. The top engine had 140 HP. The Ecotec won't appeal to everyone but it should be a very valid choice for people who consider cars to be appliances rather than extensions of their personal identity.
      • 6 Years Ago
      Oooh, four cylinder Buick achieving the same highway MPG as the old fullsize 3.8L Buicks of a decade ago. Stop the presses!
        • 6 Years Ago
        Are you adjusting the numbers to the new EPA procedures? If not, you're comparing old apples to new oranges.
        Anyway, this makes a lot of sense for a base model, and hopefully it will reduce the sticker shock, but GM really needs to bring over the Insignia as the entry-level car as the LaCrosse is a rather large and content-filled car.

        A 2000 LeSabre gets 17/27, according to the new EPA estimates, so this is a mild upgrade. I think the problem is that this is too heavy of a car to really reap any economy benefits of a four-cylinder engine. I reckon it's a move made purely for cost.
      • 6 Years Ago
      So wait, who buys Buicks again? I don't know anybody who would buy a Buick... I'm almost 30, and even my older friends, no way. So who is the target market here? Still old people?
        • 6 Years Ago
        I never thought I would buy a Buick until I saw this car. I had a 3 series for a few years (2003 model) and my wife drove a Volvo (2006 S40) for a few years and compared with either the 2010 Lacrosse I test drove puts both to shame despite being 10k less expensive then the BMW especially in terms of interior apportionments. The Buick is just a beautiful car inside, it feels like a car that is far more expensive then its under 30k price tag. I would not be embarrassed at all to buy it and drive it and I'm 26, hardly in the former Buick "demo".

        I didn't actually decide to buy it only because I test drove it before the 4 cyl engine became an option. I just couldn't justify to myself buying a sub 30 MPG highway car and so went with the 32MPG Equinox instead. When I trade in my 2006 G6 convertible though in a few years I will give Buick a very serious look, which would never have been the case even a year ago.
        • 6 Years Ago
        I'm 27, own a G8 GT, and would consider buying this car if I wasn't focused on the performance aspect of my vehicles. It's a nicely styled, and nicely appointed car all around.
        • 6 Years Ago
        I really don't see anybody I know being even remotely interested. Slizzo, I doubt you would EVER roll in a Buick, if you drive a G8. Ever. I just don't get the target demographic for this car, as I don't see any families picking this up, I definitely don't see single guys picking it up, girls would want something cuter or more badass, and ... I just don't get it. Who buys this thing?
        • 6 Years Ago
        The market for this car would be someone who wants a stylish, roomy sedan with lots of features. The kind of people who might buy a TL or ES350. I would buy one and i'm your age. Enclave buyers were 10 years younger than previous Buick owners. Most people I see in Enclaves appear to be in their 40s. You call that old?
        • 6 Years Ago
        Yeah Rob, older people like me. I would consider a Buick. Their best feature is tasteful looks! But, there's the very high quality ratings. And now, excellent fuel efficiency.

        Too bad the rest of GM doesn't measure up!

        Anyway, I've seen comments like this so many times. What's wrong will old people's money?? Sure, most of us won't be around 40 years from now, but we DO have money to spend. Most of us aren't in debt up to our eyeballs! If GM is interested in building Buicks that we like...why do you have a problem with that?
        Go explain it to your grandmother!
        • 6 Years Ago
        The target market is for people who don't assume Buick is for old people on default.
        • 6 Years Ago
        Smart people buy Buicks, Buicks are wonderful cars, just because you're not smart doesn't really affect Buick.
      • 6 Years Ago
      this is not a good idea, this engine should be in te 2011 regal
      • 6 Years Ago
      It doesn't matter what the average age of a Buick owner is, if you build the right cars then people will buy them. Hyundai is changing quickly what people perceive of their brand with each new vehicle they bring out. GM, Ford, Chryler (Fiat), can change people's perceptions as well if they bring out good vehicles.
      • 6 Years Ago
      Having driven many Le Sabre rental cars of the 90's, I can tell you first hand that those cars got 30 MPG on the highway, even if their adjusted EPA rating would be 27. Sometimes the information online doesn't transfer to the real world.
      • 6 Years Ago
      lol, is anyone even paying attention to how this car looks, its features, and its price point? Everyone keeps saying who would buy this. Why dont we actually LOOK PAST the badge guys. This is a VERY nice vehicle. I'm 27 and I would drive one as my daily no problem.
        • 6 Years Ago
        And you'd never get laid. Ever. Except maybe at a Bingo tournament.
        • 6 Years Ago
        lol, if you need a certain type of car to get you laid, I feel bad for you.
        • 6 Years Ago
        Rob, you are assuming women have the same taste as you do in cars. It's entirely possible a lot of classy and attractive women would see the attraction and value in a well-designed, quiet, tasteful and feature-laden car. A lot of guys do too.
        • 6 Years Ago

        you're a douche.
        • 6 Years Ago
        As opposed to pulling up in a Chevy Aveo or Hyundai Sonata? The back seats look pretty comfy for some exciting lovemaking sessions!
        • 6 Years Ago
        I don't NEED a car to get laid, but owning a buick would PREVENT one from getting laid. If you pull up in a Buick, a girl is going to think you're taking little blue pills, and might wet the bed afterwords.
      • 6 Years Ago
      Does anyone else find it odd that the 2.4L DI four with 6-speed transmission is slated to make 20/30 MPG city/hwy in a midsized car like the LaCrosse, but that same engine and transmission combination is rated at 21/32 MPG city/hwy in a midsized SUV like the 2010 Chevy Equinox? I would have assumed the LaCrosse would have a more aerodynamic profile, use similar or lower rolling resistance tires, and weigh less. What gives?
        • 6 Years Ago

        What gives?

        Extremely conservative mileage estimate?
      • 6 Years Ago
      P.V., my family and I have owned many 3800 cars over the years. All of them go around 30mpg hwy. No EPA there, that's my own ownership experience.

      And look past the badge? The badge means a lot, as evidenced by how badly all of GM's brands have completely cratered including Buick.

      Everyone is going to buy an ES or TL or something else instead. The only people who will be buying this Buick will be the same people who've always bought them, retirees. The Enclave didn't do anything meaningful for Buick's overall sales numbers and marketshare. It's still losing buyers and it's still a dead brand. No different than Mercury or Pontiac or Lincoln.

      This four cylinder car wearing a dead badge and a stupid name isn't going to change that.
        • 6 Years Ago
        Actually jackass the Enclave has been a success and outsells the MDX every single money. It also attracts younger buyers and sells for a premium relative to the vehicle it replaced.

        If you say "everyone" will buy a TL (which is selling slowly so far) or an ES over this you are essentially saying Buick wont sell one single car. You sound like an idiot.

        Unlike the TL this car actually has some grace and dignity. The TL looks like its aimed at 21 year olds who want to drag race with the stereo blasting.
        • 6 Years Ago

        Your critique is interesting, because I've heard the Buick logo called the "Tri-shield". Hmm.

        Anyway, Buick sales have indeed fallen, but it is indeed because they only sell 3 models, 2 of which are built on ancient platforms.

        Buick has 3 models, but they outsell Mercury, which has 5 AND Lincoln, which also has 5.

        In fact, of GM's divisions, the Buick division's sales-per-model is much higher than Pontiac's, Cadillac's, Saturn's, Saab's, and Hummer's. It's only slightly behind GMC.

        I'm 26, and if I had the money and was in the market, I'd definitely get a LaCrosse. Best-looking - inside and out, great economy, and full of quality and character.
        • 6 Years Ago
        Okay well I bought a Lincoln MKZ and buld parts for them along with the Fusion (www.cd3performance.com) . Im not a retiree nor are my customers with Lincolns that contact me. And my mom is buying this new buick after my recommendation and she has never had a buick before and isnt a retiree so your opinion isnt absolute. Times are a changing sir(ESPECIALLY in the auto industry).
      • 6 Years Ago
      Isn't this basically a Pontiac G6? If it is, they had the same 2.4L & 3.6L engines.
        • 6 Years Ago
        No, this is not on the same platform as a G6. That Pontiac as well as the Aura and The Cherolet Malibu are all built on the Epsilon I platform. The '10 Buick LaCrosse is built upon the Epsilon II LWB (long wheel base) platform. The only other cars riding on the EPII are SWB (short wheel base) platforms are the Opel/Vauxhaul Insignia and Chinese Market Buick Regal.
        I am 34, I am waiting to check this car out against a Cadillac CTS. One of them will replace my POS 2004 Infiniti G35 Coupe.
      • 6 Years Ago
      TriShield, Buick's poor sales reflect the fact that it sells only three models, and of them only the Enclave to this point was truly modern. The Lucerne, while decently styled for a large car, is long in the tooth and soldiers on with such non-competitive equipment as a 4 speed automatic. Buick sales will only recover with product, and a well screwed together luxury mid-size with a range of engines is the beginning of it.
