2013 Buick Regal arrives with advanced eAssist powertrain and 36 highway mpg

Article by Christian Andrei, on September 3, 2012

Buick’s upgraded sedan – the 2013 Regal with eAssist – has a starting price of $29,990, including destination, which is $2050 higher than the 2012 model. Buick announced earlier this year that for the 2013 model year, the Regal will use the eAssist mild-hybrid system as standard equipment. The price increase is mainly due to the addition of eAssist, which was formerly a standalone option that costs $2000.

The base 2.4-liter I-4 has been phased out. Instead, the 2013 Regal is now available with three powertrain options rather than three. Offered as standard equipment is an 182-hp 2.4-liter I-4 matched with a 15-kWh electric motor. Buyers could pay more to get a turbocharged 2.0-liter I-4 (with either 220 hp in the Regal Turbo or 270 hp in the GS). All Regal models have a six-speed automatic as standard. In addition, Buick offers a six-speed manual on the Regal GS and Turbo Premium III as a no-cost option. Buick also made the non-GS turbocharged engine as basically a no-cost option.

Both the Regal Premium I and Regal Turbo Premium I trims have a starting price of $31,520. This represents a price hike of $2145 and $375 for naturally-aspirated and turbo models, respectively. The Premium I package offers passive keyless entry, rear parking assist, and remote start. Going further up, there’s the Premium II package, which comes with features like HID headlights, a set of 18-inch alloy wheels, and a Harmon/Kardon surround-sound audio system. The 2.4-liter or the 2.0T are priced from $32,930, a $2145 hike for the former and $375 for the latter. The Regal Turbo will get a top-spec Premium III trim that is priced at $34,100, which means that it’s $295 higher than its comparable 2012 model.

It comes with items such as 19-inch wheels and adaptive suspension. The top-of-the-line Regal GS is priced $145 higher at $35,865. It can be distinguished from the lower models with its distinct front and rear fascias, unique suspension tuning, Brembo brakes, and a boost of 50 hp more. It’s clear that the 2013 Buick Regal is undercutting its competition but not by a significant amount. The 2012 Acura TSX costs $915 more than the Buick.

Meanwhile, the 2013 Volkswagen CC is priced $1445 higher. The TSX is available as standard with a 2.4-liter I-4 that delivers 201 hp. The CC’s standard 2.0-liter turbo-four offers 200 hp. The two contenders provide six-cylinders as options, surpassing the Regal GS’s output. The models from the Acura and the VW with the 3.5-liter V-6 deliver 280 hp. For the added power, the V-6 TSX has a starting price of $36,445 while the V-6 CC has a base price of $38,555.

Powertrain Innovation Comes Standard on 2013 Regal

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 brand’s history.

“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 buying hybrids.”

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 six-speed automatic.

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.
