DETROIT – The 2013 Buick Regal luxury sport sedan arrives at
dealerships this fall with a standard advanced eAssist powertrain and
36 highway mpg. Two powerful turbocharged four-cylinder engines give
Regal one of the most technologically advanced engine ranges in the
"With eAssist, Buick is redefining what a 'conventional
powertrain' means to customers," said eAssist global chief
engineer Stephen Poulos. "It changes the fuel economy – but not
the experience – for the 97 percent of new car buyers who aren't
Where a hybrid vehicle requires a complex system of large, heavy
batteries and electric motors, Buick eAssist uses a compact
lithium-ion battery and a small electric motor/generator in place of
an alternator to achieve an EPA-estimated 36 highway mpg for both the
Regal and the LaCrosse luxury sedans.
The three main advantages of the eAssist system are its stop/start
functionality, which turns the engine off when the vehicle is at rest;
regenerative braking that gathers and stores energy that would
otherwise be lost during braking, and an electric motor assist that
reduces the gas engine's work during acceleration or on inclines.
"It takes advantage of the best parts of a hybrid, and eAssist is
now standard equipment for Regal," said Poulos. "These new
functions happen seamlessly, a requirement for Buick drivers who
demand a refined driving experience. They'll really only notice a
difference at the pump."
Buyers interested in more acceleration can choose from a no-cost
option of a 220-horsepower, 2.0L turbocharged Ecotec engine or the
270-hp Regal GS, both with variable valve timing and direct injection.
In addition to one of the most power-dense engines ever certified by
the Society of Automotive Engineers, the GS offers high-performance
Brembo brakes, HiPer strut suspension technology and unique design
cues inside and out.
Both Regal Turbo and Regal GS are offered with automatic or manual
transmissions; Regal with eAssist is available exclusively with a
The Buick Regal name, which celebrates its 40th anniversary in 2013,
is a powertrain innovation pioneer. In 1975, it was the only mid-size
vehicle in the United States to forego a standard V-8 engine for a
more efficient V-6, while remaining competitive in performance. Three
years later, the Regal employed a turbocharger.
"In 1978, Buick was the only mainstream brand offering a
turbocharged engine," said GM Heritage Center Manager Greg
Wallace. "Only small, performance-oriented brands like Porsche
and Saab were experimenting with the same technology at the time. It
was very progressive of Buick to offer a turbocharged V-6 in a
mid-size luxury coupe in the late '70s."
Regal powertrain engineers continued that innovation 19 years later,
when the 1997 Buick Regal GS debuted with the brand's first
supercharged V-6, rated at 240 hp and 280 lb-ft of torque. It was
among the most powerful and efficient vehicles in its segment and
still achieved 28 highway mpg.
Today's Buick Regal combines sport sedan handling with intelligent
powertrain technologies. Regal with eAssist offers five more highway
mpg than an Acura TSX and six more than a Volvo S60, while the Regal
Turbo and Regal GS offer more power than turbocharged four-cylinder
engines from Audi, Mercedes-Benz, and Volkswagen.
