Demand for Fuel-Efficient Vehicles

DETROIT – General Motors dealers in the United States reported 215,358 total sales in June, an 11-percent gain compared to June 2010.

For the month, Chevrolet Cruze had retail sales 153 percent higher than the Chevrolet Cobalt it replaced, and total sales above 20,000 for the third straight month.

“With continued strong consumer demand for GM’s fuel-efficient vehicles, June was another solid month for us,” said Don Johnson, vice president, U.S. Sales Operations. “The month caps a successful first half of 2011 for us in the U.S. market – our sales are up and we’ve gained share profitably.”

In the first half of 2011, GM dealers in the United States have reported 1,261,633 vehicles sold – a 192,056 unit increase over the first half of 2010 – leading to total and retail market share gains.

Compared to last year, June fleet sales decreased 1 percent due to a planned decline in sales to rental accounts. Sales to commercial accounts rose 31 percent – the 15^th consecutive month of commercial sales gains. Fleet deliveries accounted for 27 percent of GM’s total sales for the month.

The all-new Buick Regal continued to appeal to new consumers, recording 3,497 retail sales. For the month, approximately 30 percent of Regal sales were turbo models. Cadillac CTS retail sales rose 16 percent, spurred by continued strong demand for the all-new CTS Coupe.

Year-to-date through June, retail sales for GM’s passenger cars rose 43 percent.

Chevrolet Sales Increase 11 Percent in June

Tenth straight month of retail gains, fueled by demand for Camaro, Cruze, and Equinox

DETROIT – Chevrolet sold a total of 156,848 vehicles in June, an 11-percent increase over the same month a year ago. That number includes a 16 percent increase in retail sales – the tenth consecutive month of retail sales gains for Chevrolet – driven by consumer demand for Camaro, Cruze and Equinox.

Total Camaro sales increased 13 percent and retail sales increased 19 percent compared to June of last year. Camaro continues to be the best-selling sports car in the United States, with a total of 48,761 sales for the first six months of 2011. More than 20 percent of this year’s total sales have been the Camaro Convertible, which arrived at U.S. dealers in late February.

After driving a Camaro Convertible SS, DigitalTrends.com wrote:

“The 2011 Chevy Camaro Convertible emits a voluminous mix of thunderous exhaust and engine roar. Driving down the road, this low-slung pony car felt like it could suck a small dog into the engine; make the chandeliers shake in a third-floor apartment building, and power through traffic like a thundering locomotive… Chevy has outdone itself with the redesigned Camaro.”

Cruze recorded a total of 24,896 sales for June, marking the third-consecutive month that sales exceeded 20,000. The success of the Cruze has increased Chevrolet’s total share of the compact-car segment from 9.5 percent a year ago to 11.9 percent for the first five months of 2011, even as the segment size grew by 19 percent.

Total sales for the Equinox increased 56 percent in June, while retail sales climbed 79 percent over last year. Equinox remains one of the hottest-selling vehicles on the market, spending an average of just 19 days on dealer lots.

Buick Sales Rise in June; Up 35 Percent in First Half of 2011

Regal’s second-best sales month fuels Buick’s 21^st straight month of retail sales gains

DETROIT – Buick achieved its 21^st consecutive month of retail sales gains in June, spurred by Regal’s second-best month of sales since its launch in spring 2010.

Buick retail sales grew 19 percent, year over year, with total sales up 13 percent. The first half of 2011 saw Buick’s retail sales increase 35 percent and its total sales grow 34 percent, with significant gains in Miami, Phoenix, New York and Houston.

“By choosing Regal, LaCrosse and Enclave over competitor models, luxury car and crossover shoppers have made Buick one of the fastest growing major automotive brands in the United States,” said Brian Sweeney, U.S. vice president of Buick & GMC Sales and Service. “With more new models coming to our showrooms this year, we expect even more consumers to discover Buick.”

Demand by individual customers for Regal continued to grow in June, nearly matching its best month of sales since its launch in December. Retail sales of the sport sedan were up 6 percent while total sales were down 17 percent, month over month, with 45 percent of buyers coming from non-GM brands.

Lindsay Kemner of New Jersey recently traded in a Honda Accord coupe for a Regal after considering comparable models made by Nissan, Infiniti and Honda.

“I love the look of the Regal, and when I first drove it I was impressed by how smooth it is,” said Kemner, a 24-year-old registered nurse. “Everyone I’ve shown it to really loves it.”

The all-new Regal Turbo, which launched in spring, accounted for a third of the sport sedan’s retail sales in June. The turbo’s 2.0-liter direct-injection four-cylinder engine delivers better horsepower and torque than the Acura TSX and Volkswagen CC, and with its manual six-speed transmission, it also delivers better fuel economy, with an EPA-rated 32 mpg highway.

The Regal lineup will grow in the second half of the year with the introduction of the fuel efficient 2012 Regal eAssist and the performance-oriented 2012 Regal GS. The GS, which arrives at dealerships this fall, was recently SAE-certified to deliver 270 horsepower (201kW) and 295 lb.-ft. of torque (400Nm) for an estimated 0-60 mph performance of 6.7 seconds.

LaCrosse retail sales were up 2 percent over May, but down 3 percent through the first half of the year. Total LaCrosse sales grew 25 percent month over month, but were down 4 percent calendar year to date. LaCrosse sales are expected to return to growth this fall with the introduction of the 2012 LaCrosse with eAssist™, which is expected to deliver class-leading highway fuel economy of 36 mpg.

Enclave momentum continued to grow in June with retail sales up 11 percent and total sales up 7 percent, calendar year to date. One reason for the Enclave’s sales success is its fuel economy, 24 mpg highway (FWD), which is better than any eight-passenger crossover.

Enclave, a four-time winner of Consumer Digest’s Best Buy award, has the highest “conquest” rate of any Buick, with 48 percent coming from non-GM brands. Approximately 41 percent of all Buick buyers come from non-GM brands and 19 percent come from imports.

“Almost every day we’re seeing customers who want to trade in a Lexus, Infiniti or BMW for a Buick,” said Mark Whibbs, dealer principal of Vince Whibbs Buick in Pensacola, Fla. “Many of our new customers are young professionals who can buy whatever they want, and they’re choosing Buick.”

Buick is a modern luxury brand offering vehicles with sculpted designs, luxurious interiors with thoughtful personal technologies, along with responsive-yet-efficient performance.

GMC Sales Grow in June; Up 24 Percent in First Half of 2011

Terrain, Acadia drive 21^st straight month of gains; Sierra achieves best month of year to date

DETROIT – GMC delivered its 21^st consecutive month of retail sales gains on strong demand for its fuel-efficient trucks, crossovers and SUVs, with retail sales in June up 18 percent year over year and total sales up 15 percent. The brand hit the mid-year mark with retail sales up 24 percent and total sales up 23 percent, with significant gains in Phoenix, New York, Boston and Atlanta.

“GMC’s blend of fuel efficiency and professional grade capability continued to attract new customers to its dealerships in June,” said Brian Sweeney, U.S. vice president of Buick & GMC Sales and Service. “Retail sales of Terrain and Acadia combined grew 44 percent year over year last month, and total sales of Sierra HD trucks are up 34 percent so far this year.”

With its segment-leading fuel efficiency, rugged styling and flexible interior, Terrain achieved a 75-percent increase in retail sales and a 52-percent increase in total sales for the month of June compared to 2010. The smaller SUV, which is EPA-rated for 32 mpg in highway driving, finished the first half of the year with retail sales up 52 percent and total sales up 53 percent.

Army Major Elvis Mabry, stationed at Fort Dix in New Jersey, recently traded in a Toyota RAV4 for a Terrain after test driving comparable Toyota, Honda and Ford models, including a hybrid. He liked Terrain’s size, fuel efficiency and price, which starts at $24,500.

“I’ve driven Toyota for many years, but I definitely wanted to buy an American car this time around,” Mabry said. “I did a lot of research before buying and was very excited that Terrain has what I was looking for. The options are just fantastic. The in-dash nav system is easy to use and the adjustable seats are a lot more comfortable than in the Toyota.”

Acadia, which is EPA-rated for 24 mpg in highway driving, also excelled in June, with retail sales up 23 percent and total sales up 7 percent. The crossover, which offers better highway fuel range than Honda Pilot and Ford Explorer, also delivered gains for the first half of 2011, with retail sales up 17 percent and total sales up 13 percent.

Acadia and Terrain combined continue to represent 44 percent of GMC’s sales calendar year to date, and are in a dead heat for the highest conquest rate, with Acadia narrowly leading. More than half of all Acadia and Terrain customers are coming from non-GM brands. Approximately 46 percent of all GMC buyers come from non-GM brands.

Demand for Sierra picked up in June, particularly for heavy duty models. Retail HD sales were up 35 percent and total HD sales were up 39 percent year over year, and up 29 percent and 34 percent, respectively, for the calendar year.

In June, the entire Sierra lineup’s retail sales grew 18 percent over May, with total sales up 15 percent. Sierra lineup’s retail sales grew 20 percent and total sales rose 22 percent for the first half of the year.

In June, Yukon/XL’s combined retail sales were up 18 percent over May, and its combined total sales – retail and fleet – were up 2 percent year over year. The Yukon lineup’s retail sales grew 9 percent and total sales rose 8 percent for the first half of the year.

Yukon/XL recently placed second in the 2011 J.D. Power Initial Quality Study^SM, in the large crossover/SUV segment, exceeding the segment average score by 7 percent. In the same study, GMC scored within the Top 10 industry brands, ranking 10^th overall. GMC moved up 15 positions compared to last year’s results.

A contributing factor in GMC’s continued sales growth is its Denali lineup, which blends the brand’s professional grade capability with exclusive styling and premium content. Demand for the trim level has more than doubled this year, with Denali models now accounting for over 16 percent of GMC total sales and contributing to 21 consecutive months of GMC sales increases.

“Our Denali customers are leaving Toyota, Mercedes, Volvo and Acura, just to name a few,” said Greg Pollice, general sales manager at Burns GMC in New Jersey. “These customers are accustomed to premium quality and are impressed with the uniqueness of Denali. We are selling them as quick as we can get them.”
