GM U.S. Sales Increase 8 Percent in July on

Cruze, Crossover Demand

DETROIT – Driven by continued strong demand for the company’s lineup of fuel-efficient cars and crossovers, and by improving full-size pickup truck sales, General Motors dealers in the United States reported 214,915 total sales in July, an 8-percent gain compared to July 2010.

Retail sales for GM’s brands rose 6 percent for the month compared to a year ago, and were 1 percent higher than June.

In July, total sales of the Chevrolet Cruze were above 20,000 for the fourth-straight month, delivering 24,648 units. The 32 miles-per-gallon highway-rated GMC Terrain and Chevrolet Equinox compact crossovers saw a combined retail sales increase of 73 percent during the month.

Total sales for GM’s full-size pickups – Chevrolet Silverado and Avalanche, and GMC Sierra, increased 2 percent from June, while retail sales – those to individuals – rose 5 percent compared to last month.

“Sales of our fuel-efficient cars like the Chevrolet Cruze and our crossovers remain strong, and we’re now also seeing the seasonal lift in full-size pickups that we expected,” said Don Johnson, vice president, U.S. Sales Operations.

The U.S. auto sector has faced several significant headwinds in the past several months. Nonetheless, the industry is poised to regain some of its lost momentum in the second half of the year, aided by higher supply and pent-up demand.

“There are people who put off vehicle purchases because of uncertainty about fuel prices, vehicle availability and the economy,” Johnson said. “As these conditions improve in the latter half of this year, many of these buyers will return to the market.”

GM’s 2011 U.S. industry forecast, originally announced in January, remains unchanged at 13 million to 13.5 million units, but the company expects total industry sales to end the year in the low end of this range, Johnson said.

Passenger Cars

Total sales of GM passenger cars increased 8 percent during July, compared to a year ago. Retail sales for cars rose 9 percent for the month on the continuing strength of the Cruze. The Cruze Eco, which delivers an estimated 42 miles-per-gallon highway, accounted for 19 percent of the model’s retail sales during the month.

The all-new Buick Regal continued to appeal to new consumers, more than doubling retail sales from a year ago. For the month, approximately 33 percent of Regal sales were turbo models. Chevrolet Camaro retail sales rose 7 percent, as demand for the all-new convertible model continued to rise.

Year to date through July, retail sales for GM’s passenger cars are up 37 percent.

Crossovers

Total crossover sales increased 20 percent compared to last July, while retail sales climbed 17 percent. Retail sales of Equinox and Terrain were up 75 percent and 67 percent respectively, while retail sales for the GMC Acadia improved 33 percent.

Year to date through July, retail sales of GM’s crossovers increased 25 percent.

Full-Size Pickups

Compared to June, combined sales of Silverado, Avalanche and Sierra sales increased 2 percent, and retail sales rose 5 percent. Silverado retail sales increased 7 percent, compared to June, while Sierra retail sales rose 2 percent compared to last month – the best month of the year for GMC’s full-size pickup.

Total sales of GM’s full-size pickups declined 3 percent versus a year ago.

“The increase in industry sales of full-size pickups is consistent with our forecast, as more truck buyers come back into the market,” Johnson said. “We expect continued modest growth in the segment for the remainder of the year, and are positioned to meet the increase in demand.”

For the year to date through July, total pickup sales of 306,439 units represent a 9-percent increase compared to the same period in 2010. For the year, retail sales for GM’s full-size pickups are up 9 percent. Through July, estimated retail market share for the Silverado, Avalanche and Sierra has grown more than 2.5 percentage points.

Fleet and Commercial

Compared to last year, July fleet sales increased 13 percent, as the company posted its 16^th consecutive month of commercial sales gains.

Fleet deliveries accounted for 26 percent of GM’s total sales for the month.

Month-end dealer inventory in the United States stood at about 538,000 units, down about 67,000 units compared to June and about 115,000 units higher than July 2010.

Their Lowest Cost to Own recognition is another reason why Equinox continues to bring more and more customers to Chevrolet.”

Buick Sales Stay Hot in July

Enclave, LaCrosse and Regal propel Buick’s 22^nd straight month of retail sales gains

DETROIT – Buick achieved its 22^nd consecutive month of retail sales gains in July, up 1 percent year over year. The luxury brand’s retail sales have increased 28 percent and its total sales have risen 27 percent year to date, with significant gains in Dallas, Washington D.C. and Chicago.

“Luxury car and crossover shoppers have made Buick one of the fastest-growing automotive brands in the United States by choosing Regal, LaCrosse and Enclave over competitor models,” said Brian Sweeney, U.S. vice president of Buick and GMC Sales and Service. “Buick’s product renaissance and customer-focused dealer network are attracting new interest in the brand, and with new models coming to showrooms we expect even more growth.”

Enclave delivered its best month of the year in July with retail sales up 24 percent over June, and total month-over-month sales up 53 percent. 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 24 percent of Enclave buyers come from imports – 5 percentage points higher than in June. Forty-one percent of all Buick buyers come from non-GM brands.

“Enclave was an immediate hit when it arrived and continues to attract a lot of new customers to the brand. The same is true of LaCrosse and now Regal is coming on strong,” said Dave Sinclair, president of Dave Sinclair Buick-GMC in St. Louis, Mo. “The word of mouth has been great for Buick. Almost every new customer who comes in says the same thing: ‘I heard that Buicks are really nice. And then I saw one on the street and knew I had to drive one.’”

LaCrosse retail sales were up 8 percent in July over June, with total month-over-month sales equal to the previous month. LaCrosse sales are expected to continue to grow this fall with the introduction of the 2012 LaCrosse with eAssist™, which is expected to deliver class-leading highway fuel economy of 36 mpg.

The eAssist system also will deliver a higher mileage option on the 2012 Regal later this year. In addition, the performance-oriented 2012 Regal GS will join the sport sedan lineup this fall. Regal retail sales were up 1 percent in July over June for its second best sales month since its launch in spring 2010. Approximately 45 percent of Regal buyers come from non-GM brands.

The all-new Regal Turbo has accounted for a third of the sport sedan’s retail sales since its launch this past spring. 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.

New-to-Buick customer Justin Curran said he loves driving his Regal Turbo on the curvy coastal and mountain roads near his home in Anacortes, Wash., where the 31-year-old emergency room doctor also enjoys mountain biking and skiing.

“Regal Turbo has everything I want in a car – it’s both fuel-efficient and fun to drive,” said Curran, who purchased the car from Dewey Griffin Buick in Bellingham, Wash. “I fell in love with it at first sight, and when I found out about the manual option I just had to have it. It is awesome how quickly this car gets up to speed and hugs the corners. Regal Turbo definitely isn’t grandpa’s Buick.”

Edmunds.com recently named Regal the highest rated sedan in the $20,000 to $30,000 category based on new vehicle owners’ satisfaction ratings.

GMC Sales Heat Up in July

Terrain, Acadia, Sierra and Yukon drive 22^nd straight month of retail sales gains

DETROIT – GMC delivered its 22^nd consecutive month of retail sales gains in July, with sales to individual customers up 17 percent and total sales up 36 percent year over year, with significant gains in Phoenix, New York, Miami and Los Angeles. July also was GMC’s best month of the year so far, with retail sales up 23 percent and total sales up 25 percent.

“Strong demand for fuel-efficient crossovers and SUVs continued to attract new customers to our dealerships in July,” said Brian Sweeney, U.S. vice president of Buick and GMC Sales and Service. “We are also seeing a seasonal lift for our Professional Grade trucks as expected.”

Terrain led the sales growth in July by achieving a 67-percent increase in retail sales and a 93-percent increase in total sales compared to 2010. The smaller SUV’s EPA-rated fuel economy of 32 mpg in highway driving leads the segment.

Recent Terrain buyer Doug Smolev of Purchase, N.Y., traded in his BMW 750, because the commercial property developer and father of three needed a flexible, fuel-efficient vehicle.

“My wife and I are always taking our kids either to hockey rink, baseball field or soccer field,” Smolev said. “The Terrain’s 60/40-split rear seatback lets us put lots of gear into the back and still have room for the kids. And, because it has a four-cylinder engine, Terrain gets much better fuel economy rating than other SUVs.”

Another GMC known for its fuel efficiency and interior flexibility is Acadia, which excelled in July, with retail sales up 33 percent and total sales up 87 percent. The crossover gets better highway fuel range and offers more cargo space than Ford Explorer, with room for up to eight passengers.

Terrain and Acadia crossover combined represent 46 percent of GMC’s sales calendar year to date retail, and are in close competition 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.

Sierra delivered its best sales month of the year in July, driven by increased demand for heavy duty models. Retail HD sales were up 29 percent and total HD sales were up 34 percent year to date, and nearly as much in both categories year over year. Retail sales for the full Sierra lineup grew 2 percent year over year, with total sales up 6 percent.

“We just sold a couple of HD Denali trucks the other day, and our Sierra sales in general have been brisk, with many Tundra trade-ins and a lot of repeat customers,” said Dwight Everett, president of Everett Buick-GMC in Bryant, Ark. “Our customers recognize that GMC delivers a blend of high quality, capability and value that few other brands offer.”

Yukon/XL delivered its best sales month of the year in July, with retail sales up 7 percent, and combined total sales – retail and fleet – up 10 percent year to date. Combined total sales also

were up 21 percent year over year. Yukon recently took top honors in the full-size SUV category of AutoPacific’s 15th annual Vehicle Satisfaction Awards, delivering value and satisfaction across a wide range of attributes.

GMC’s Denali lineup continues to contribute to the brand’s sales growth. Denali blends capability with exclusive styling and premium content. Demand for the trim level has more than doubled this year, with Denali models now accounting for 16 percent of GMC retail sales.

About GMC

GMC has manufactured trucks since 1902, and is one of the industry’s healthiest brands. Innovation and engineering excellence is built into all GMC vehicles and the brand is evolving to offer more fuel-efficient trucks and crossovers, including the Terrain smaller SUV and Acadia crossover. GMC is the only manufacturer to offer three full-size hybrid trucks with the Yukon, Yukon Denali SUVs and the Sierra pickup. The new Sierra Heavy Duty pickups are the most capable and powerful trucks in the market.
