Improvements to the 1987 model 911 Coupe, Targa and Cabriolet -- Porsche's classic race-bred sports cars -- include a hydraulically assisted new clutch, a new five-speed gearbox and a gain in horsepower through use of optimized combustion developed from the company's racing engines.

The new clutch and transmission allow smoother movements from gear to gear, with a changed gear pattern.

The six-cylinder Carrera engine with optimized combustion has gained 14 horsepower without any total weight increase and now produces a total of 214 hp with a top speed on a test track of 149 mph and a 0 to 60 mph time of 6.1 seconds under test conditions.

The 911 Carrera has fresh colors and additional leather trim options as well as new fully adjustable electric comfort seats with additional lumbar support.
