Automotive sales for June showed a healthy boost for the Detroit 3 automakers with Chrysler posting the largest increase of 30 percent compared to June 2010, which moves them ahead of Toyota as the third largest-selling automaker. Honda, Subaru and Toyota still struggled from supply issues related to the March tsunami and earthquake. Hyundai also continues to gain momentum. Here are the results:

Chrysler had the largest increase of all with a 30 percent jump over last year—the biggest increase since 2007. So far this year, the automaker is up 21 percent. The Jeep Compass, Grand Cherokee, and Patriot all had strong gains.

Ford’s sales were up 14 percent over last June and 12 percent year-to-date. Strong sellers include the Escape, Explorer and new Focus.

General Motors posted a 10 percent increase over last year and is almost 17 percent higher over last year for the first 6 months of 2011. The Chevrolet Cruze led the charge with over 24,000 units sold. The Equinox posted a 50 percent gain and the GMC Terrain was up 46 percent. The Cruze and Malibu were the highest selling models for the month (besides pickups) passing the popular Toyota Camry and Honda Accord.

Honda saw a 24 percent drop over the last year and is almost 2 percent down so far in 2011. Supply issues have hurt sales for all models from last June. However, the Fit, has increased 20 percent.

Hyundai continues to do well with an increase of 16 percent from June 2010 and is up 26 percent so far this year. The Elantra and Sonata lead the lineup.

Nissan saw sales increase 11 percent from last June and is up 14 percent so far this year. The Altima and Sentra both posted strong gains.

Subaru sales dropped 8 percent over last June, but still are up nearly 5 percent in 2011. The Legacy and Outback both posted double-digit increases.

Toyota has been hardest hit from the Japanese earthquake and posted a 24 percent decline over last year. Year-to-date, the automaker is down 4 percent. Most models posted a decline over last year except for the FJ Cruiser, Highlander, and Scion tC.

Toyota is expected to resume full production by September. We’ll see next month whether the American automakers can continue their momentum and if the Japanese can bounce back.
