There is plenty of buzz surrounding Porsche's upcoming 991-generation 911 models and CAR Magazine out in the United Kingdom has revealed some more details on various 991 future derivatives. There aren't any overwhelming surprises with the upcoming model announcements, but it's clear that Porsche will be moving swiftly to launch several models out of their 991 generation in the upcoming years.

Once the standard Carrera and Carrera S models arrive at the end of this year, we're expected to see the 911 Cabriolet next featuring a stylish soft-top. The end of 2012 should bring Porsche's next generation Carrera 4, bringing four-wheel-drive to the Carrera and Carrera S models. It's believed that the C2 and C4 will feature a 3.4L engine with 350-bhp and 280 lb-ft of torque, while the C2S and C4S will pack 400-bhp and 325 lb-ft of torque from a 3.8L.

By 2013, the new 911 Turbo will arrive, featuring a fun-filled 3.8L, 520-bhp power plant. The standard 911 Turbo should be followed up by a soft-top variant in 2014. 2013 should also bring a new GT3 model, featuring a high-revving naturally aspirated flat-six engine.

Way down the road in late 2013 or early 2014 will be Targa and Speedster versions of the 991-generation 911. Rumor has it that Porsche's product planning department looks to bring back the MkII targa, which featured a folding removable top and a heated glass backlight. Though the Speedster variant hasn't been confirmed yet, it wouldn't surprise any of us to see Porsche create a Speedster based on the 991 Cabriolet.

Last but not least, a 911 hybrid should be in the works as well, thanks to Porsche's success with their 911 GT3 R Hybrid. We'll stay tuned for upcoming, official releases from Porsche but for now, we have plenty to look forward to with the new 991 generation.
