Between the launch of the 2014 Mercedes S-Class, the debut of the S63 AMG (shown above) and reports about a new "super S-Class," the Mercedes-Benz flagship sedan has been in the news a lot lately. According to Car and Driver, Mercedes plans to introduce three new flavors of the latest S-Class at the Frankfurt, LA and Detroit auto shows.

We already heard that the plug-in hybrid version will be introduced at the Frankfurt Motor Show in September, but this new report says that the V12-powered S65 AMG and S600 models will soon follow. At the LA Auto Show in November, the S65 AMG will hit the stage with a twin-turbo V12 expected to produce more than the current model's 621 horsepower. This should make for one quick S-Class, no doubt able to shave a few ticks off the 2014 S63 AMG's 0-60 time of 3.9 seconds.

Following the S65's debut, Mercedes will reportedly take the wraps off its S600, which will use a less-powerful version of the mighty V12. The 2013 model year S600 produces 510 hp from its 5.5-liter twin-turbo V12, which is enough to propel the sedan to 60 miles per hour in 4.5 seconds. The updated version should only improve those figures. Stay tuned.
