Porsche 911 America Roadster (964) (1992 - 1993)
The American Roadster is essentially a turbo-bodied Carrera Cabriolet with Turbo suspension and brakes. Like the 356 America Roadster it was named after, the Type 964 America Roadster was a limited-edition, driver-focused convertible destined for the American market. Production for the America Roadster was limited at only 250 examples, and the model was only produced in 1992 and 1993. Its engine was a standard unit making 250 horsepower, but the special edition had the wide fender flares, suspension, brakes, and 17-inch Porsche Cup wheels of the 911 Turbo.
Porsche 911 Carrera 2 Targa (964) (1990 - 1993)
Like the Carrera 4, the Carrera 2 was available as a coupé, Targa or Cabriolet. This was the last generation Targa with traditional removable Targa roof (till 991). It sold ok, with 3,534 units sold over its lifetime. The engine was the 3.6 liter unit which produced 250 horsepower and a maximum speed of 162 mph while the 0 to 60 mph acceleration was made in about 5.6 seconds. Performance was on par with the coupe and it is the looker in the 964 range.
Porsche added the rear wheel drive Carrera 2 variant to the range in 1990. It was developed alongside the 964 Carrera 4, Porsche waited a year to release the Carrera 2 as a 1990 model year car. Like the Carrera 4, the Carrera 2 was available as a coupé, Targa or Cabriolet. Think of the cabriolet as a C2 coupe but with a fabric roof and more fun and you are right on the money. It was popular amongst buyers, particularly in the United States, with a total of 11,013 units sold, making it the third most popular 964 model. 
Porsche 911 Carrera 2 Coupe (964) (1990 - 1994)
Porsche added the rear wheel drive Carrera 2 variant to the range in 1990. It was developed alongside the 964 Carrera 4, Porsche waited a year to release the Carrera 2 as a 1990 model year car. Like the Carrera 4, the Carrera 2 was available as a coupé, Targa or Cabriolet. Overall, the Carrera 2 packed almost the same technical specifications as the Carrera 4 model. The engine was the same 3.6 liter unit which produced 250 horsepower and a maximum speed of 162 mph. Looked like C4 but was 200 lb lighter and more fun to drive.
Porsche 911 Type 964 Carrera 2 'Works Turbo Look' Cabriolet was a special model in the 964 lineup. It gave buyers of the Carrera 2 Cab the great wide look of the Turbo cars and the Carrera 2 engine. The model was available as a 1992 and 1993 model year car (while some argue it was also available for a while in 1994). You get body shape of the 964 Turbo 3.3 without the huge rear spoiler. But this was more than just a design exercise, because the the Turbo-Look models also got the chassis and braking system from the Turbo 3.3 too.
