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.
