deer and lost control, then struck on a tree. The drive got killed, while
none of the airbags deployed. I wonder what the outcome would have been if
the car were a bigger and heavier one?
From one Corolla to another, it is a JOKE! Cherish your life, get a better

但你過高估計重量重要性, 低估了吸能
速度改变率是速度的改变量和所用时间的比
in your formula, v1-v2 is change of speed, or acceleration a
a = Δv/Δt
如果當速度差是一個常數, 例如 60kmph -> 0kmph, 那可能影響 a 的就是 Δt.
如果車在0.5秒撞停, a = 60 / 0.5 = 120
如果車在0.6秒撞停, a = 60 / 0.6 = 100
20% difference
(I know I am using wrong units in the calculation, but just to show the
relative difference)
also, american cars are not much heavier than japanese cars:
2011 Honda Accord Sedan LX 3269 lb
2011 Toyota Camry LE 3307 lb
2011 Ford Fusion SEL 3342 lb

发帖数: 5754 | 7 in a collision the truck-based large SUV is safer than a uni-body car-based
minivan because the a) truck-frame does not cave-in during a collision and b
) the truck is heavier. It causes more damages to the other party. As a
result, you pay a higher insurance premium for SUV (that's the 相关的数据
from insurance company). |

accord
minivan is safer than sedan because a)
the seating level in minivan is close to that of SUV, and higher than the
seating level in sedan. and b) its weight is closer to SUV and heavier than
sedan.
a frame (truck frame) is chassis made from high strength steel/metal so it
can haul/tow heavy load off road. truck-based SUV is a box build on this
frame and inherited this sturdy feature. Uni-body cars are mostly made of
sheet metal.
Traverse has partial frame (according to some Chevy forum_). |

For FWD minivan,
a) value - Sienna > Odyssey
For similar configuration, sienna is less expensive than odyssey. For
example, you can get a basic rear-view camera for Sienna LE. But for Odyssey

basically a G35 wagon.

Achieving maximum acceleration or hill climbing, while avoiding engine
speeds higher than a certain limit (e.g. 3000 or 4000 RPM), is difficult
since it requires avoiding triggering the kick-down-switch. Avoiding
triggering the kick-down-switch requires a good feel of the throttle pedal,
but use of full throttle can still be achieved with a little sensitivity as
the kick-down button is only activated beyond the normal full opening of the
accelerator pedal.

Usually front wheel drive cars are easier to get going in slippery
conditions because front end of the car (where the engine bay is) is heavier
than the back (trunk).
That's why people put sandbags/weights in the trunk of their rear wheel

When the total length of a SUV and minivan is the same, why minivan has more

This is b/c SUV has a longer head, therefore longer buffer zone for survival

And SUVs are generally heavier, therefore they are safer ( of cause you may
