General Motors posted an 11.4-percent sales gain in April, selling 237,646 vehicles. All four of the GM brands saw car sales increase last month compared to April 2012.
Winner: Chevrolet Silverado -- 39,395 sales, up 28.1 percent
Even though buyers know that the all-new 2014 Chevrolet Silverado goes on sale later this year, they still snapped up the current version GM's popular pickup truck. The GMC Sierra enjoyed a 12.8-percent year-over-year sales gain to move 14,208 units. Combined, the GM pickup trucks slot in between those from Ford and Chrysler Group: the F-Series sold 59,030 copies last month while the Ram tallied 31,409 sales.
Winner: Chevrolet Sonic -- 8181 sales, up 27.6 percent
Small cars sold well last month, with the Cruze closely following the Sonic's sales gain. It rose 21.0 percent versus April 2012 to sell 22,032 cars. That makes the Cruze GM's second best-selling model, after the Silverado. The teensy Chevrolet Spark sold 3121 units in April, its second-best monthly result this calendar year after selling 3538 cars last year.
Winner: Chevrolet Tahoe -- 9052 sales, up 54.9 percent
The big Tahoe SUV posted the highest year-over-year sales gain of any GM vehicle last month, even though its overall unit sales were mid-pack within the Chevrolet brand. It seems impending CAFE regulations and higher gas prices haven't killed off sales of full-size SUVs just yet.
Sort-Of Winner: Chevrolet Camaro -- 7949 sales, down 17.4 percent
Camaro sales fell off significantly compared to last April, but the car still came out ahead of its rivals. The Ford Mustang sold only 7751 cars last month, and the Dodge Challenger found just 4804 buyers. Score that as a win for the Camaro.
Waiting Patiently: Chevrolet Corvette, Chevrolet Impala, Cadillac CTS
All three of these models suffered major sales declines for the same reason: production of the old car has slowed in anticipation of the new model's launch. Chevrolet sold 974 Corvettes last month, down 30.2 percent from a year prior simply because production of the outgoing C6-generation car has ceased. Impala sales dropped 26.9 percent to 10,943 because the improved, all-new version only arrived in showrooms by the middle of April. And Cadillac CTS sales sunk 42.9 percent to 2398 as buyers await the 2014 version that bowed at the New York auto show; it goes on sale in the fall.
Loser: Chevrolet Volt -- 1306 sales, down 10.7 percent
Chevrolet's much-hyped range-extended electric car continues to sell relatively slowly, and sales fell by a noticeable margin compared to last April. Overall, though, Volt sales are up 3.2 percent for the first four months of 2013 versus the same period in 2012.
Loser: Cadillac SRX -- 3478 sales, down 13.0 percent
The SRX crossover is usually the bright star in the Cadillac lineup, selling in decent numbers even when the discontinuation of other models (primarily the STS and DTS) killed the brand's overall sales figures. But last month sales slipped by a percentage eclipsed only by the CTS's aforementioned sales struggle. The SRX was still Cadillac's top seller, even beating out the brand new ATS (2725 sales) and XTS (2891 sales).
