General Motors 2010 Calendar Year Sales Up 21 Percent;

December Sales Increase 16 Percent – Best Month of 2010

DETROIT – General Motors dealers reported 223,932 total sales in December, a 16-percent increase from a year ago for the company’s four brands. The gain was driven by solid retail sales which were 27 percent higher than a strong December a year ago. For the calendar year, total sales for GM’s four brands increased 21 percent to 2,202,927, while retail sales rose 16 percent for the year. GM’s four brands sold 118,435 more vehicles this year than the company did with eight brands in 2009, and will gain total and retail market share for the year.

The December total sales result includes an anticipated reduction in fleet sales to rental companies. For the month, overall fleet sales represented 17 percent of GM’s total sales.

According to Don Johnson, vice president, U.S. sales operations, the company’s annual sales performance shows the strong focus of the new company.

“Our sales this year reflect the impact of GM’s new business model,” Johnson said. “The consistency of results that we achieved demonstrates the focus on our brands, dealers and customers, and how we compete aggressively for every sale, every day.”

In December GM’s industry-leading lineup of fuel-efficient crossovers continued to gain in popularity with consumers. Sales of GM crossovers rose 42 percent versus December 2009. For the year, GM crossover sales were 50 percent higher than in 2009. GM sold 567,458 crossovers in the United States in 2010, far more than any other automaker.

Since 2005, the crossovers’ proportion of the U.S. market has almost doubled to about 22 percent of the industry. In the same period, crossovers as a proportion of GM sales have increased more than threefold and now represent 26 percent of the company’s sales volume.

“The crossover market is a great example of how consumers can have their cake and eat it too,” Johnson said. “More and more, consumers are choosing to purchase fuel-efficient crossovers like the 32-mpg highway-rated Chevrolet Equinox and GMC Terrain because they get everything they want – comfort, utility and quality.”

In December, sales of the Chevrolet Equinox and GMC Terrain set records for each model (22,764 and 9,303 respectively) and led GM’s crossover gains – a result of improving availability. For the year, sales of these compact crossovers were up 74 percent and 331 percent respectively, enabling them to gain market share in the compact crossover segment where sales rose an estimated 27 percent year-to-date through December. In the mid-luxury crossover segment, the Cadillac SRX gained more share than any entry, with sales up 152 percent for the year.

GM’s full-size pickup truck sales improved 29 percent in December versus a year ago, when the company was clearing out a high proportion of past model-year trucks. During the month, 89 percent of GM’s full-sized pickup trucks sold were 2011 model year vehicles compared to 22 percent new model year trucks (2010) during the same month last year. In 2010, combined sales of the Chevrolet Avalanche, Chevrolet Silverado and GMC Sierra full-size pickups increased to 520,444 units – up 17 percent compared to 2009.

Total sales of GM passenger cars declined 6 percent during December, driven by anticipated lower fleet sales. However, retail sales of GM passenger cars rose 14 percent for the month, led by improving demand for the all-new Chevrolet Cruze, Buick Regal and Cadillac CTS Coupe. For the year, sales of GM passenger cars improved 20 percent.

Month-end dealer inventory in the United States stood at about 511,000 units, which is about 25,000 lower compared to November and about 126,000 higher than December 2009.

Buick Sales Surge 40 Percent in December

Enclave, LaCrosse and Regal Energize Buick’s 52 Percent Year-Over Year Increase

DETROIT – Buick, the fastest-growing major automotive brand in the United States, finished 2010 with its best sales month of the year, delivering a 40 percent year-over-year increase in total sales for the year.

December marked Buick’s 15^th consecutive month of retail sales gains with a 48 percent increase over 2009.

With each passing month, Enclave, LaCrosse and Regal increasingly attract new customers to the brand. Approximately 41 percent of Buick buyers come from non-GM brands, of which 27 percent come from imports. Each of the three models earned Consumer Digest’s “Best Buy” award in 2011 – the year when MOTOR TREND magazine declared “Buick is Back.”

“The accolades and awards that Buick earned in 2010 were great, but winning new customers and giving them a reason to remain loyal through our improved dealer services was the key to Buick’s growth in 2010,” said Brian Sweeney, U.S. vice president of Buick & GMC Sales and Service. “We expect the brand to grow even stronger in 2011 with the arrival of our all-new luxury sport sedan, the 2012 Buick Regal GS.”

Enclave had its best retail month since its launch, with its retail sales up 40 percent versus December 2009 and up 27 percent year for the calendar year. Likewise, total sales for the luxury crossover were up 22 percent for the month and up 28 percent for 2010.

LaCrosse continued to excel in 2010, attracting non-GM and import buyers at the same rates as the brand overall. LaCrosse’s retail sales soared 112 percent in 2010, and total sales were up 120 percent for the calendar year.

Regal had its best month in December since its launch last spring, surging 54 percent in both retail and total sales compared to November, sparked in part by the recent arrival of the Regal CXL Turbo.

“Regal’s dynamic driving experience and intuitive, personal technologies offer customers a premium sport sedan for great value,” said Roger McCormack, Buick Marketing director. “The all-new CXL Turbo’s Interactive Drive Control System takes Regal’s performance to a whole new level by enabling the driver to choose between standard, touring and sport driving styles.”

Said George Peterson, president of AutoPacific, a marketing research and consultancy firm: “Buick’s solid 2010 performance has been helped by pulling former Pontiac buyers into the brand – since many or all shared dealerships – and because Buick has a critically acclaimed lineup of vehicles – LaCrosse, Regal and Enclave. Buick’s future performance looks promising as well with new products added to broaden the appeal of the brand.”

About Buick

Buick is a modern luxury brand offering vehicles with sculpted designs, luxurious interiors with thoughtful personal technologies, along with responsive-yet-efficient performance. Buick is attracting new customers with its portfolio of award-winning models, including the Enclave crossover, LaCrosse sedan and Regal sport sedan. The new Buick Verano compact sedan and

GMC Terrain Tops Off 2010 with Best Sales Month Ever

Acadia, Sierra and Yukon Help Drive GMC to 15^th Straight Month of Sales Gains

DETROIT – GMC Terrain, the compact SUV that delivers a segment-leading 32 mpg, capped its first full calendar year in December with its best sales month since its introduction in September 2009. Terrain’s year-over-year retail sales grew 73 percent in 2010 and total sales grew 68 percent during the same period. Terrain is averaging just 19 days on dealer lots compared with a 32-day average among competitor models.

“Terrain was red-hot in December. We sold more than twice what we normally sell,” said Robert Morris, dealer principal, Morris Cadillac, Buick & GMC in greater Cleveland. “People are finding out that – with the Terrain – they can have the utility of an SUV and the fuel efficiency of a passenger car.”

Terrain’s gains, along with year-over-year improvement for Acadia, Sierra and Yukon, helped GMC achieve its 15^th consecutive month of sales increases. GMC’s year-over-year retail sales improved 40 percent in December, and were up 36 percent for the calendar year.

More than any other GMC, Terrain is attracting both female and non-GM customers. Approximately 46 percent of Terrain buyers are women, which is more than 20 percentage points higher than the overall brand. In addition, 50 percent of all Terrain buyers are coming from non-GM trade-ins.

“Terrain is helping GMC grow by attracting customers who previously might not have considered an SUV or crossover,” said Brian Sweeney, U.S. vice president for Buick & GMC Sales and Service. “Together with Acadia, GMC’s crossover SUV sales are stronger than ever and we expect them to continue growing in 2011.”

Acadia had its best month of the year in December, delivering a year-over-year retail sales increase of 46 percent and a 30 percent increase for the calendar year. Acadia’s total sales increased 27 percent compared to December 2009 and were up 27 percent for the year. More than half of all Acadia sales come from non-GM brands.

Acadia sales were fueled in part by the recent arrival of the new 2011 Acadia Denali, which distinguishes itself from other crossovers with unique cues, including a chrome honeycomb grille, monochromatic exterior and 20-inch two-tone chrome-clad wheels.

Sierra also had its best month of the year in December, with retail sales up 40 percent year over year, and up 17 percent for the year. Total Sierra sales were up 38 percent year over year and 16 percent at year’s end. Last summer’s arrival of the new 2011 Sierra Denali 2500HD and 3500HD, the first offerings of the exclusive Denali line on a heavy-duty GMC pickup, has helped spur sales in 2010.

Yukon and Yukon XL also finished 2010 on a high note, with Yukon/XL collectively up 26 percent year over year in retail sales. Yukon notched a 17 percent year-over-year increase in total sales, while Yukon XL improved by 31 percent.

“GMC is benefitting from the resurgence of the full size pickup and SUV market, strong Terrain sales and very good Acadia sales,” said George Peterson, president of AutoPacific, a marketing research and consultancy firm. “Having GMC and Buick now solidly paired helps both brands and gives Buick/GMC a strong platform for future growth.”

About GMC

GMC has built trucks since 1902, and is one of the industry’s healthiest brands. Today GMC is evolving to offer more fuel-efficient trucks and crossovers, including the Terrain small SUV and Acadia crossover. The new GMC Sierra Heavy Duty pickups are the most capable and powerful trucks in the market. Innovation and engineering excellence are woven into all GMCs, including the Yukon and Yukon XL and full line of Sierra pickups. Today GMC is the only manufacturer offering three full-size hybrid trucks. Details on all GMC models are available at www.gmc.com, on Twitter at @thisisgmc or at www.facebook.com/gmc.

Cadillac is Fastest-growing Major Luxury Brand in 2010

U.S. sales rise 35 percent for full year; December sales up 13 percent

DETROIT – Cadillac capped off a strong year as U.S. sales rose 35 percent in 2010 to 146,925, making Cadillac the fastest-growing major luxury brand in the United States. Cadillac reported December sales of 16,718, up 13 percent compared to the same period last year.

Cadillac’s retail sales rose 36 percent for the full year and 28 percent in December for the best total and retail sales months since March 2008. Cadillac has reported 11 straight months of year-over-year total and retail sales gains.

Cadillac’s positive sales momentum was driven by the addition of new or redesigned models and the launch of key customer service initiatives. Cadillac achieved double-digit sales increases for the year in 18 of the top 20 markets, including New York, Los Angeles, Miami, Dallas, Atlanta, Chicago, Denver and San Diego.

Redesigned for the 2010 model year, the SRX quickly earned a spot among the leaders in the luxury crossover segment. SRX sales were up 18 percent in December to 5,865 and rose 153 percent for the full year to 51,094. December marked the best total and retail sales ever for SRX.

The award-winning CTS family continued to attract customers to Cadillac. The CTS Sport Wagon joined the line-up for the 2010 model year and the CTS Coupe launched in the second half of the year as a 2011 model. Sales of CTS increased 24 percent in December to 5,171 and 18 percent for the full year to 45,656.

Escalade also gained strength as the year progressed. Escalade had sales of 3,814 in December, up 16 percent compared to December of 2009. It was Escalade’s best total and retail sales month in two years. Escalade sales rose 4 percent for the full year to 26,874.

In addition to the new and redesigned models, Cadillac rolled out new initiatives in 2010 to appeal to luxury car buyers. Cadillac and its dealers partnered with hotelier Ritz-Carlton on a series of training programs to elevate the customer experience in showrooms and in service departments. For the 2011 model year, Cadillac added Premium Care Maintenance, providing Cadillac owners with many frequently required maintenance services for the first four years or 50,000 miles.

“Cadillac and its dealers made a concerted effort in 2010 to take all aspects of our business to new levels,” said Kurt McNeil, vice president for Cadillac sales and service. “As the luxury auto market recovered, Cadillac was poised to provide customers with compelling new products and enhanced service. We’re confident these efforts will continue to pay off for the brand and reinforce our place as the New Standard of the World.”

About Cadillac

Cadillac has been a leading luxury auto brand since 1902. In recent years, Cadillac has engineered a historic renaissance led by artful engineering and advanced technology. More information on Cadillac can be found at media.cadillac.com.
