New Buick Models

Owned by General Motors, Buick is one of this country's oldest brands, with a rich tradition of innovation that dates back to the turn of the century. Aimed at traditional American luxury-car buyers, Buick cars tend to place a priority on a plush ride rather than sporty performance. Although historically known for catering to retirement-age customers with its full-size sedans, the automaker's lineup now includes SUVs and minivans designed to bring younger buyers into the showrooms of Buick dealers.
The company was founded in 1903 by David Dunbar Buick, a Scottish industrialist. He built his first car in 1904; called the Model B, it had a two-cylinder engine with an advanced-for-its-time overhead-valve cylinder head design. In 1907, Buick unveiled its first four-cylinder production car, dubbed the Model D. The following year, the Flint, Michigan-based Buick Motor Company was bought by William C. Durant as part of a new company called General Motors. By 1914, all Buicks were built with six-cylinder engines and purchased primarily by upper-class professionals, thus earning the nickname "doctor's cars."
The manufacturer proved itself a trailblazer in the early 1920s when it introduced four-wheel brakes. This technology had been seen before on custom-built cars, but Buick was the first to figure out how to successfully apply it to mass-produced vehicles. Eight-cylinder Buick cars emerged in the 1930s and became immensely popular; these advanced engines received steady improvements for several years. The '30s also saw Buick's introduction of the industry's first rear turn signal to use a flasher.
Models such as the Estate Wagon and the ever popular Roadmaster kept Buicks happily ensconced in driveways all across the nation in the 1940s. In 1948, Buick introduced Dynaflow, the first torque converter-type automatic transmission offered in U.S. passenger cars. The 1950s and 1960s witnessed Buick continuing to zoom ahead of the curve; it was among the first to offer vehicles with power brakes and steering, and 12-volt electrical systems. The marque was also behind the introduction of the first American V6 passenger car engine and introduced the Riviera personal luxury coupe in the early '60s.

On the whole, though, Buick had made its name as a manufacturer of stately land yachts such as the Electra 225. To meet the changing times, the automaker downsized its full- and midsize models during the 1970s and began offering compact and midsize sedans for the 1980s. Since then, Buick has varied its approach to its lineup. It's dabbled in performance cars (the Regal Grand National) and luxury coupes (the two-seat Reatta luxury coupe) but its core product continued to be luxury sedans aimed at an older audience.
Today, Buick specializes in sedans and crossover SUVs and is modifying its philosophy in hopes of attracting younger buyers. Luxury and class are still common themes but new models have European influences to enhance sport and desirability. As such, many modern Buicks provide a more entertaining drive and more contemporary styling than people might expect from this "old" nameplate.

Upcoming Baby AMG May Get Supercharged V-6, Not Turbo Four

Upcoming Baby AMG May Get Supercharged V-6, Not Turbo Four
British magazine Autocar reports that the upcoming B-Class-based AMG sedan will be powered by a 3.2-liter supercharged V-6, not a turbocharged four-cylinder as previously thought.

The mill is based on the upcoming 3.5-liter engine that'll first make its home in the new CLS350. Also like the CLS, the smaller AMG (codenamed the *** EVO) will get similar coupe-like styling, meaning four frameless doors and a steeply raked profile.


Force feeding the engine is said to be an electronically operated pressure wave supercharger. The technology is widely used in tractor and big diesel applications, and utilizes pressure waves from the exhaust to boost engine induction.

Rumors persist that a seven-speed dual-clutch transmission will handle what is believed to be around 400 horsepower.  Though the car will be based on a front-drive platform, AMG will likely opt for an all-wheel drive setup to help put power down.

Though smaller and less powerful than its siblings, the "baby Benz" (the nickname was originally applied to the shown 190 E EVO II) will not be a cheap means to gain access into the premium performance segment. It'll still carry all the premium bits - and driving characteristics -- AMG customers are used to, but at a slightly lower price point in order to make way for newer, younger buyers.

Mercedes-Benz Considering Making S-class Hybrid-only?

Mercedes-Benz Considering Making S-class Hybrid-only?
With mostly large V-8s and twin-turbo V-12s in its lineup, the Mercedes-Benz S-class isn’t particularly fuel-efficient. In light of upcoming fuel economy standards, Daimler executives reportedly are considering making the S-class a hybrid-only lineup.


According to Automotive News, inside dealer sources said Daimler executives are considering the switch to all gasoline-electric models for the next-generation S-class. If the switch is made, the dealer sources say that no S-class will be offered with only an internal combustion engine -- including the high-performance AMG versions. The fact that even the Autobahn-storming AMG models would become hybrids has drawn criticism from U.S. dealerships because they worry hybrids are not perceived as true performance cars in this market.

As of right now, only a few U.S. Mercedes dealerships have been briefed on the proposed plan. Those dealers will meet with Joachim Schmidt, head of sales and marketing at Mercedes-Benz Cars, this week at The Masters golf tournament in August, Georgia. Mercedes is a tournament sponsor.

Currently, the most fuel-efficient S-class is the recently introduced S400 Hybrid with a fuel economy rating of 19/26 mpg (city/highway). From there, the ratings continue to decline all the way down to 11/17 mpg for the top-of-the-line S65 AMG. According to Tommy Baker, chairman of the Mercedes-Benz dealership board in the U.S. and owner of a Mercedes dealership in Charleston, South Carolina, this doesn’t matter to S-class buyers. He says that for S-class buyers, the “goal is not gas mileage.”

“The most important thing in the American market -- regardless of hybrid, lithium, or electric cars -- is that we Americans are different than any market and we are going to want those gasoline engines,” Baker told Automotive News. To that end, Mercedes-Benz has already announced a new, more fuel-efficient 5.5-liter twin-turbo V-8 to replace the company’s 6.2-liter V-8 in its “63” AMG models.

Although Baker says the all-hybrid S-class lineup may not fly with U.S. consumers, an average combined rating of 16 mpg and emissions of a similar level won’t fly with the government’s upcoming fuel economy and emissions standards. Two Daimler sources told Automotive News that the move is being considered to help Mercedes reach the strict European CO2 emissions laws and the U.S. fuel economy standard by mid-decade. A final decision on the matter is expected within three months and, if approved, would be implemented on the next-generation S-class due out in Europe in 2013 and a year later in the U.S.

BMW, Mercedes-Benz Fight to Outsell Each Other in China

BMW, Mercedes-Benz Fight to Outsell Each Other in China
BMW may have outsold Mercedes-Benz globally in 2009, but the two German automakers are both vying to be the biggest luxury brands in the Chinese market.


For the time being, BMW holds that title. Over the past six years, its marketshare in China has grown from 16 to 23 percent, but BMW isn’t resting on its laurels. At the Beijing auto show, CEO Norbert Reithofer announced the company has increased its 2010 sales forecast (which includes BMW, Mini, and Rolls-Royce vehicles) by 20 percent, bumping the total to 120,000 units. In contrast, BMW sold 90,500 vehicles in China in 2009.

New vehicles tailored to the Chinese market -- like the new long wheelbase 5 Series sedan -- will likely help BMW achieve that goal, but the automaker sees the potential to grow over the long term. Reithofer believes his company can build as many as 300,000 vehicles annually in China, thanks in part to an expanded joint venture with Brilliance Automotive Holdings. BMW is expanding its existing plant in Shengyang, which builds the 3- and 5 Series lines, but is also building a second facility, which may build the X1 crossover for the market.

Daimler was a little less forthcoming with specific goals for its Chinese market strategy, but said it simply plans on outselling BMW by 2011. The automaker believes a number of products, designed exclusively for Chinese customers, will help propel it to the top of the sales charts. In addition to launching a new line of heavy-duty trucks for commercial clients, Mercedes-Benz will ultimately launch an electric car co-developed with Chinese automaker BYD, and a long-wheelbase C-class sedan.

Of course, these plans for domination assume another German rival -- Audi -- isn’t able to turn about its fortunes in China. Although it had been the leading luxury brand in the market for the last 20 years, Audi has seen its marketshare slip over the last six years, falling from 66 to 46 percent. Should the firm’s new A8L or the forthcoming A7 fastback resonate with Chinese buyers, BMW and Mercedes-Benz both have their work cut out for them.

Mercedes-Benz to Style Helicopter Interiors, Yachts, and Furniture

Mercedes-Benz to Style Helicopter Interiors, Yachts, and Furniture
You aren't likely to spot a helicopter parked next to an E-Class  at your local Mercedes-Benz dealer anytime soon, but designers employed within the automaker's styling studios are lending a hand in creating a number of non-automotive products.


We first saw the AMG-branded Cigarette racing boat back in February, but it seems the sleek vessel was just the tip of the iceberg. Daimler revealed today a number of different assignments doled to its designers, ranging from helicopter cabins to luxury yachts and everything in between.

"We are in no way entering into new territory," says professor Gorden Wagener, head of design at Mercedes-Benz Style.  "Our design team has already styled such products such as watches and interiors, as well as numerous products for Mercedes-Benz accessories. Our design division has all of the necessary expertise in more than ample measure, and has benefited from such skills for many years."

As is the case with BMW's Designworks studio, Mercedes-Benz Style can be hired by outside firms to provide design work for future products. Although we'd be a little surprised to see Daimler's stylists penning vehicles that would compete against its own wares, Wagener says the operations has its foundations in land, sea, and air transportation, so anything goes.

Although Daimler itself is no longer attached to the EADS consortium or its Eurocopter subsidiary, M-B's first project was to create the cabin for the new Eurocopter EC145 luxury helicopter. Reportedly inspired by the R-Class crossover, the helicopter has seating for eight, which can be quickly reconfigured or removed to make room for more luggage. Buyers can select from a number of different trim materials and wood patterns, while a three-color ambient lighting system is culled from the S-Class.

Wagener sets no bounds on M-B Style's activities, but does insist clients "must match our premium standards and represent innovation, as well as trend-setting, enduring style." Look for the design operation -- which is comprised of 400 employees from 20 different countries -- to have a hand in many more products in the years to come.

Vexing Hex: Iranian Designer Pens 6-Wheel Mercedes-Benz Off-Roader

For now, the Unimog remains Mercedes-Benz’s most potent off-road machine -- but we rather like the ideas presented in the design concept crafted by Iranian engineer Siyamak Rouhi Dehkordi.

Dubbed the Mercedes-Benz Hexawheel, the conceptual off-roader utilizes -- of all things -- six wheels. The hallowed portal axles of the Unimog are abandoned in favor of independent suspension at each wheel, but the frame itself is truly interesting.


Like the unusual M561 Gamma Goat military vehicle, the Hexawheel sports a vertically articulated frame, which is hinged around the axis of the center pair of wheels. Dehkordi says the design allows for substantial vertical articulation -- the frame can theoretically travel 28 degrees up and 30 degrees down. A pair of hydraulic rams controls the articulation, provides dampening, and in some instances, work to help push the Hexawheel over large obstacles.

Unlike the Goat, which sported steering on its front and rear axles, the Hexawheel’s rear trailer pivots side-to-side, allowing the 16-foot long vehicle to have an 18-foot turning radius. Further enhancing its prowess off-road is its balanced drivetrain. Dehkordi’s design calls for a diesel-hydraulic drive system, with the engine, pump, and accumulators placed underneath the pickup bed. The fuel tank, located under the cab, helps distribute truck’s 4850-pound curb weight.
We think this is a neat design -- but our only reservation lies with torsion. Long-travel suspension does help traverse obstacles, but when it comes time to twist -- like the Gama Goat does when climbing this hill -- we’d be curious to see how the Hexawheel performs in the real world. Sadly, we think this will remain a digital flight of fancy for the foreseeable future.

Brabus Gives Mercedes-Benz SL65 AMG Black Series More Power, More Black Paint

In its search for more power, Brabus created the T65 RS using the Mercedes-Benz SL65 AMG Black Series and endowed it with 788 horsepower and 811 pound-feet of torque.
Starting with an already exclusive SL65 AMG Black Series, Brabus modified the factory twin-turbo 6.0-liter V-12 with some additional components. Two new exhaust manifolds with two new turbochargers were fitted to the twelve-cylinder engine, as were four large intercoolers to really get the air flowing. Feeding out from the engine is a stainless-steel exhaust system with free-flow cats.

To help harness the extra power, the SL65 Black Series was given a new engine electronics package that helps the car meet Euro IV emissions standards. In actuality, maximum torque is rated to an astounding 1047 pound-feet at 2100 rpm, but Brabus chose to electronically limit the car to 811 pound-feet, likely for drivability concerns. Peak horsepower is reached at 5500 rpm.

Unfortunately, extra power doesn't always translate to lower 0-to-60-mph times. We tested the standard Black Series to reach the mark in 3.6 seconds and the T65 RS posts the same number. In other performance figures, the T65 RS hits 124 mph in just 9.8 seconds and is capable of traveling in excess of 206 mph, but is also electronically governed to 200 mph.

As you can tell from the photos, the T65 RS really rides the Black Series name with its matte-black paintjob and darkened wheels. A special carbon-fiber hood scoop, black leather and Alcantara seats, and stainless-steel door sill plates with illuminated Brabus logos add the special German tuner touch.

Pricing has not been revealed, but with a starting price tag of $300,000 for the basic SL65 AMG Black Series, you can bet the T65 RS will command a premium.
