What advantage do front engines have in the event of an accident in the direction of travel?
Is the engine block also an advantageous crumple zone?

Would that be safer?
Would it be safer if everyone just drove around in a truck? In the event of an accident, less happens in a truck than in a normal car or
When I start the motorcycle I only hear a very fast rattling noise?
Good evening mechanics, Briefly, I drive a Yamaha WR125R, I have a 200cc cylinder and of course the piston installed. When I turn the piston everything works as it should, i.e. the piston is not hanging or installed crooked. The battery is freshly charged and all the lights and everything work, but this nasty rattling…
car?
If someone totals my car, they have to pay me money. Let's say I get €30,000 for my car. What happens to the wrecked car? Can I keep it?
One person too many in the car. What impact does it have on your probationary period?
ByMecrudi
Hello, I'd be interested to know what happens if you carry one person in the trunk of your car, or if four people are sitting in three seats? And you're currently on probation and you get caught. Is this a Class B violation? Does it matter how old the person is? Thank you in advance…
Alcohol residues in blood test at police checkpoint?
ByWadim479
Hey, I recently tested positive for THC during a traffic stop and had to have a blood test done. 3 hours before the blood sample I drank 150ml of beer, according to the blood alcohol calculator my body should have already broken down the alcohol Now my question is whether my blood will be tested…
The engine block is a rigid cast component, which contributes exactly nothing to the crumb zone, which is more of a hindrance.
It would be optimal to have nothing at the front except the shock absorbing materials in the body longitudinal supports. Even the wheels are disturbing.
All cars known to me have a crumb zone which extends approximately to the front axle or the spring domes. Behind it the inner “hard” part of the body begins.
You’d have to make it clear if you’re talking about a series engine installed longitudinally or transversely? Or a motor in V-shape or a boxer engine? The size of the engine compartment would also play a role. Also the width of the car and the space between the front seats. And the question of whether there is a cardan shaft and where the gear is placed.
And you should explain what would be installed in a car with a rear motor in the front.
As flat as you asked the question, it is not to answer.
Strangely, the article about VW Buse simply speaks of rear and front engines without more precise specification. How can the author only expect the readers to understand the article without your above mentioned comments. Blamage.

What should not be understood about the Wikipedia article? The various models of the VW bus are listed there. This has nothing to do with a crash test
Hello GrandVoyager
Knautsch zones are deformable parts, the engine block is a fixed component and not deformable.
Greetings HobbyTfz
Depending on the strength of the accident, the front engine can live.
Rear motor/medium motor is mostly for light sports cars, where only the trunk is at the front.
the engine is sturdy and can protect the passenger with a frontal collision.
So Formula1 is not just high because of the very high speed?
You can’t compare an F1 car with a road vehicle.
These are extremely lightweight construction with carbon parts etc. What also has another splitter behavior/knautsch zone.
If they weren’t crashing into old tires, they wouldn’t be much left by the driver in concrete.
The engine at the front protects no one. Rather the opposite is the case. The engine is more of a problem in an accident. The engine is sitting there because it is easy and inexpensive to use it.
In the case of sports cars, the medium-engine design is used because of the focus of the vehicle
Can tell what you want.
The engine in front saves life.
Look at real frontal accidents.
Compare quiet “normal” cars and sports cars
I’m aware of the focus.
But when it comes to safety, a V8 S class in a front accident is better than a Porsche 911.
simply because more mass is at the front.
How do you want to know if the same A. class with rear motor would be safer? Such a car does not exist, and consequently no crash test.
A-Class with front motor much safer than different.
You compare different bodies with each other. S-Class A-Class and Porsche 911 are of different design. If so, you would have to the Vehicle, compare with front, sometimes with rear motor.
I’m aware of how that means only if you didn’t know it or are at the latest there are constructions to absorb these forces. Also on the front engine. Even the first A-class is built so that the driver sits much higher and thus is guided under the driver in the best case when the engine impacts.
and we are talking about a frontal accident and not North Korea, who suddenly shoot engines into passenger compartments.
Vehicles are designed so that as good as nothing can happen in front/center and rear motors themselves convertibles receive additional struts on the underfloor to ensure stability due to the missing roof.
If front engines are so dangerous and engines come into the passenger compartment, they would not be permitted.
In addition, there are much more front motors than rear/centre motors and I have never heard that the motor has made it right into the passenger compartment.
Just find it funny how people just have to talk about everything.
Conclusion:
In frontal accidents, it is simply safer if in front of one of the motors the force is absorbed.
That’s what it was about me.
You didn’t understand what I wrote, did you? When the motor with its 200kg presses against the spray wall, so that is correct, it often happens that the motor crushes the foot space so that the legs of the driver are clamped. This happens only by the weight of the engine. Also in the front engine you only have the two carriers that swallow the energy and discharge it into the rest of the vehicle. In the case of a medium or rear motor constructions, you have much more possibilities to derive the energy and they have no metal block pressing against the spray wall.
By the way, since the transmission and the motor are firmly screwed to one another, both parts possibly press into the interior space there no motor crashes on the transmission. A cardan shaft is also flexibly mounted and also provided with articulated joints. She doesn’t stop there.
The engine pushes it right back. Only the one comes again against the passenger outer wall and the rear drive still presses against the gear.
Don’t get me wrong but I prefer to press the force against the engine over the gearbox and passenger outside wall than on 2 struts at the rear/centre engine
The motor moves to the rear and in the most unfavorable case presses into the foot space. This is exactly the mass that becomes a problem in an accident. It is also a problem to distribute the forces that occur. With a front motor, you only have the two frames at the front that need to be sufficient for the absorption of energy. In a car with a medium or rear motor, you have the possibility to install additional elements such as the floor through a trunk, for example, to generate more rigidity and surface that, in the event of an accident, swallow all energy without a heavy engine being pushed into the interior.
No, it’s not true. On the one hand, the tire stacks are hardly good, for that it is good Techpro barriers to better absorb energy and not spring back like tires. On the other hand, many accidents in ovals have shown, for example, that the concrete walls are not so problematic, depending on the impact angle. Smurf straight on the other is unhealthy, slanted side is not that bad at all. A formula vehicle is incredibly stable in the survival cell. The splintering of the carbon produces an extremely high amount of energy, which makes the accidents almost always rightly run smoothly.
Cars with front motor have better protection in the direction of travel, since the engine is “buffer” between the driver and the collision.
The engine block is probably not a buffer.
Of course, everything is a buffer that slows down the collision until it comes to you.
Nothing.
More than nothing, huh?
What can a non-deformable engine block buffer?
None
No
