For enhanced safety, the front seat shoulder belts of the Porsche 911 are height adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The Nissan 350Z doesn’t offer height adjustable seat belts.

The 911 has standard head airbag curtains which act as a forgiving barrier between the driver and passenger’s upper bodies and the window and pillars. Combined with high-strength steel door beams and lower side airbags this system increases head protection in broadside collisions. Head airbags cost extra in the 350Z and requires Coupe.

The 911 has standard Porsche Stability Management (PSM), which uses the antilock brake hardware along with powerful software and additional sensors to detect the beginning of a skid. The PSM then intervenes by automatically applying the brake at one appropriate wheel, preventing a skid. A skid prevention system is only available on the 350Z Manual (except Base).

The 911 offers an optional backup radar to help warn drivers about vehicles, pedestrians or other obstacles behind their vehicle. This collision warning system uses radar to detect obstacles behind the rear bumper. The 350Z doesn’t offer a rear collision sensor.

Both the 911 and the 350Z have standard driver and passenger frontal airbags, front seatbelt pretensioners, four wheel antilock brakes, electronic stability systems to prevent skidding and available traction control.

For better traction, the 911 has larger standard tires than the 350Z (F:235/40R18 & R:265/40R18 vs. F:225/50R17 & R:235/50R17). The 911 S’ tires are larger than the largest tires available on the 350Z (F:235/30R19 & R:295/40R19 vs. F:225/45R18 & R:245/45R18).

The 911’s standard tires provide better handling because they have a lower 40 series profile (height to width ratio) which provides a stiffer sidewall than the 350Z’s standard 50 series tires. The 911 S’ 235/30R19 front and 295/40R19 rear tires have a lower 30 series front and 40 series rear profile than the 350Z’s optional 45 series tires.

The design of the Porsche 911 amounts to more than styling. The 911 offers aerodynamic coefficients of drag from .28 to .29 Cd (depending on bodystyle and options). That is lower than the 350Z (.3 to .34). A more efficient exterior helps the 911 go faster and keeps the interior quieter. It also helps the 911 get better fuel mileage.
