Porsche announces all-new 911 Carrera GTS

Porsche’s family of 911 models just keep growing.

The latest addition is the new GTS variant, which means the 911 family tree now includes 19 models. Announced Tuesday, the GTS gets subtle power and chassis upgrades and will come in four flavors: a rear-wheel-drive coupe and convertible and an all-wheel-drive coupe and convertible.

Like the GTS upgrades on other Porsche models in its lineup, this package on the 911 is more of a collection of popular options grouped together to save buyers a little money.

Porsche's 911 GTS will come in rear- and all-wheel-drive, and coupe or convertible variants. It goes on sale at the end of 2014.
