The 2005 Porsche 911 redesigned rear-wheel-drive models.
The models are available as coupes and convertible Cabriolets.
They all have a rear-mounted, horizontally opposed 6-cyl engine.
The redesigned Porsche 911 has subtly altered styling and dimensions
and changed the interior. There are two types of 911: The Carrera, with a
325-hp 3.6 liter engine and The Carrera S, with 355-hp 3.8 liter.
The 6-speed manual transmission is standard to all 911s. Optional,
we can choose the 5-speed automatic with manual shift gate and
steering-wheel controls. Standard, the 911s have antilock 4-wheel
disc brakes, antiskid/traction control and front side airbags. The
redesigned Careras include side airbags in the windowsills for head
protection. In the convertibles models, we find a power top and heated
glass rear window. A suspension with lowered ride height and shock
absorbers are standard on the Carrera S and optional on the Carrera. This
system helps adjusting firmness within driver selectable Normal and
Sport models. All other Porsche models have 18 inch wheels, but the Carrera
S has 19s. An option for the Carrera is a Sport Chrono Package. It includes
a dashboard-mounted stopwatch and it allows altering various engine and
chassis controls in order to improve driving performance. All 911s offer
a navigation system.
