Chevrolet Cruze Fuels 17 Percent Rise in GM

March Retail Sales

DETROIT – March capped a successful quarter for General Motors in the United States. Retail sales surged 38 percent for its four brands, driven by demand for Chevrolet’s all-new Cruze compact sedan. In spite of a decline in incentives, dealers reported 206,621 total sales during March, an increase of 11 percent. This total included a 17 percent increase in retail sales, compared to March 2010.

March’s retail sales increase was spurred by a 34-percent rise in passenger car retail sales, led by a 287 percent gain in retail sales of the Cruze over the car it replaced.

March deliveries to fleets declined 1 percent and represented 27 percent of the company’s total sales – the ninth straight month that fleet sales comprised less than 30 percent of total sales.

For the first three months, total sales increased 26 percent to 592,545 units compared to a year earlier. As a result, each of GM’s brands – Chevrolet, Buick, GMC and Cadillac – gained retail and total market share during the quarter.

“Our plan was to get out of the gates quickly in the first quarter and we succeeded,” said Don Johnson, vice president, U.S. Sales Operations. “Consumers responded favorably to the value of our broad lineup of fuel-efficient cars, trucks and crossovers.”

In the first quarter, fleet sales represented 24 percent of the company’s total sales volume, compared to 30 percent in the first quarter of 2010.

GM’s Newest Vehicles Continue to Drive Retail Gains – up 54 Percent in March

Combined retail sales for vehicles launched since June 2009 – Chevrolet Equinox, Silverado HD, Cruze and Volt; Buick LaCrosse and Regal; GMC Sierra HD and Terrain; and Cadillac SRX, CTS Wagon and CTS Coupe – increased 54 percent during March and were up 74 percent for the first three months of the year.

“March sales demonstrated our newest models continue to win over customers,” Johnson said. “Vehicles like the Chevrolet Cruze and Equinox put us in great position to benefit from consumer’s increasing desire for fuel-efficient vehicles.”

Passenger Cars

Total sales of GM passenger cars improved 15 percent during March, led by the sale of 18,018 Cruzes. Retail sales of GM passenger cars rose 34 percent for the month. The Cruze, Chevrolet Camaro Convertible and Buick Regal all have achieved record retail sales since being launched. For the quarter, retail sales of GM’s passenger cars were up 49 percent, also led by the Cruze, up 203 percent.

Crossovers

The Chevrolet, GMC and Cadillac brands each set March total and retail sales records for crossover sales during the month, driven by a 20 percent increase in combined retail sales by the Chevrolet Equinox and GMC Terrain. The two also set March records for retail sales. For the quarter, retail sales of GM’s complete lineup of industry-leading crossovers were up 30 percent.

Pickups

Total combined sales of Chevrolet Silverado and Avalanche, and GMC Sierra increased 11 percent in March, with retail sales also rising 11 percent versus a year ago. For the quarter, retail sales for GM’s full-size pickups rose 38 percent, while total sales improved to 130,866 units – a 31-percent increase.

Incentives

During March, purchase incentives declined on a per unit basis.

“We’ve said all along that our plan for the year was to be at or near industry average on incentives as a percent of average transaction prices, as we were last year,” Johnson said. “Our actions in March were consistent with that plan and we will continue to be prudent in our go-to-market approach.”

Month-end dealer inventory in the United States stood at about 574,000 units, which is about 57,000 higher compared to February and about 149,000 higher than March 2010.

Buick Retail Sales Rise 49 Percent in First Quarter

Regal, Enclave propel 18^th straight month of retail sales gains in March

DETROIT – Buick, the fastest growing major automotive brand in the United States in 2010, finished the first quarter of calendar year 2011 with retail sales up 49 percent and total sales up 39 percent. March also marked Buick’s 18^th straight month of growth with retail sales up 24 percent and total sales up 21 percent.

“Regal, LaCrosse and Enclave continue to attract new-to-Buick buyers seeking fuel efficiency, luxury and style in the midsize sedan, full-size car and crossover segments,” said Brian Sweeney, U.S. vice president of Buick & GMC Sales and Service. “We fully expect the arrival of the fuel-efficient LaCrosse with eAssist and all-new Verano luxury compact to attract even more new customers to Buick.”

Approximately 38 percent of Buick buyers come from non-GM brands and 17 percent come from imports.

Regal, which launched last April, continued to help Buick grow in March with demand for the sporty sedan accelerating thanks to increased availability of the all-new Regal CXL Turbo, which accounted for 30 percent of Regal’s retail sales in March. The turbo’s 2.0-liter direct-injection four-cylinder engine delivers better horsepower and torque than the Acura TSX, and with its manual six-speed transmission, it also delivers better fuel economy, with an EPA-rated 32 mpg highway.

Retail sales for LaCrosse also were up in the first quarter by 4 percent. The 2012 LaCrosse will feature eAssist, which uses an electric motor and lithium-ion battery to capture energy created during braking. Electric power used for starts and stops and light power boost while cruising.

Enclave, which had the strongest sales in its four-year history last year, continued to grow in the first quarter of 2011 with retail sales up 24 percent and total sales up 17 percent. Enclave’s monthly total sales also were up 8 percent year over year. So far in 2011, Enclave has the highest conquest rate of any Buick at 46 percent. The crossover delivers better fuel economy than any eight-passenger crossover, with 24 mpg highway (2WD).

“Fuel efficient vehicles and positive word of mouth continue to draw new customers to Buick showrooms,” Sweeney said. “Consumer interest in the brand also is evident by a 31-percent year-over-year increase in traffic at Buick.com, which is an important sales generator.”

Some of Buick’s hottest markets in the first quarter included Miami, New York and Houston; the latter is hosting the 2011 NCAA Final Four^® basketball tournament, of which Buick is a sponsor.

Buick’s new partnership with the NCAA started during March Madness^® and continues to generate buzz online at www.ncaa.com/buick, the home of the Buick Human Highlight Reel. This collection of videos celebrates the achievements of former student-athletes who are making a difference in their communities. Buick also is the exclusive title sponsor of a 30-minute television show featuring select Human Highlight Reel stories airing prior to the 2011 NCAA Men’s Final Four^® semifinal games on April 2.
