If this is a proper front/offset crash (and it seems it is), it shows how safe these cars are - and corroborating what was said in another thread, the price to achieve it is a heavier car, but it is worth it.
This is a crashed 997 Carrera S Cab, the "result" is even more impressive. Yes, the 911 is a very safe car, especially because there is no engine in front of the car which could move inside and cause serious damage due to the intrusion and the results of such an intrusion.
I saw several crashed 996 (no 997 yet, thanks god) in the past and they all looked like as the front passengers never got hurt seriously.

Re: Testcrash 997
RC...while intrusion of the engine is a major factor with front engine cars (a head on collision causes the dash to move towards the passenger(s), possibly causing a femur break but at the very least entrapment of the victim)...but Porsche's advantage is that there is so much space in the front to crumple. An engine obviously isnt going to compress easy...so while the front end of a Porsche will be severely crumpled (sorry crumpled is the best word I can come up with) the occupants will have a much better chance of survival because the force of the collision has been absorbed.
RC...you might have known all of this, I thought I'd post this information for other members.

This is why I mentioned it is very safe because there is no engine but you explained it much better than I did, sorry.
In German this would be "Knautschzone", the "designed" area/zone which crumples in a certain way to absorb force and therefore reduce stress to the passengers.

From what I've heard, the problem of having a front engine car during a crash was solved more than a decade ago by Mercedes Benz at a time when Mercedes HAD the reputation for building the safest cars in the world. They preferred having a rear-wheel drive layout versus front-wheel drive so that the longitudinally mounted front engine, upon impact, would have greater engine compartment space to travel below the passenger compartment instead of into it. The lack of complexity coupled with the greater space in the engine compartment of a rear-wheel drive car allowed the engine freedom to move downward and underneath as designed.
Nowadays, front-engined, front-wheel drive cars have no problem garnering high praise in independent crash tests. I do not know what engineering innovations they have that allow them to be so successful.
What about mid and rear-engined cars? Does anyone know if Porsche conducts rear-impact tests on its 911's and Boxsters and what the outcome of those tests are? The engine's path of travel in a severe rear impact is of interest since most of us travel on one-way high-speed interstates and sometimes when there is a sudden accident or heavy fog condition, a huge traffic pile-up occurs with cars, SUV's, and massive semi-trucks smashing one another severely in rear impacts. I wouldn't want to be sitting in the back seat of a 911 in this scenario.
