Porsche 977 Carrera Sports Car
Colin Jones | December 20, 2009A new Porsche 911 is always intriguing because it’s exciting to see how after more than 40 years of development the Porsche team still manages to bring alterations and advancements to this iconic exemplar.
The new 997 blends the silky modern looks of the 996 series with the fashionable retro styling of the older 911′s. The front end is finished with round lights and separate parking/fog/indicator lights. This modification, coupled with wider hips echoes the last of the air-cooled 911′s, the 993. Other changes in the body shell are the new door handles, wing mirrors and the trendy cut of the rear wings into the bumper/lights.
Even if the 997 looks a lot like the previous model, the 996, the new car is actually 38mm wider which creates a more forceful look. With each new model introduced, Porsche has attempted to lessen the drag co-efficient helping the 911 slide through the air more effectively thus increasing performance. The same thing has been done with the new car, and if we compare the 993 Cd of 0.34 to the 997`s 0.28, we can see how far the aerodynamic game has moved on. The latest body shell and rear wing combine with new under body paneling to also offer improved levels of down force for this latest generation of Porsche’s finest.
The latest Porsche model has the best handling 911 ever. Improving a car’s rigidity helps ensure that the suspension can work more effectively and while not making such a quantum leap as the team did with the 996, Porsche enhanced torsional rigidity by 8% and added as much as 40% more strength.
For their new model car, Porsche wanted to enhance crash safety provisions so they added two new air bags, which are located in the side of each front seat back-rest and are calculated to protect the thorax. They also kept the earlier two front and two side airbags, which means that now there are six air bags in total. For the same reason, that is crash safety, the reinforced body shell features additional protection such as a more widespread use of very high strength steel.
The most recent model is also 50 kg heavier than the 996. The reason is that modern crash safety regulations sort of force vehicle manufacturers to produce new cars of increased weight, despite the widespread use of a large variety of weight saving measures, such as an aluminum bonnet.
Aside from the crash safety improvements, much of the additional weight can be attributed to the higher standard specifications of the new cars. The power to weight ratio is similar with the latest car offering 233 bhp per tonne against it’s predecessors 238 but the new model’s improved aerodynamics must assist it achieve Porsche’s claimed performance figures, which are identical to those of the 996.
