The new 911 GT3 RS and the 911 GT3 |
We've always considered the laws of physics a challenge.
Thankfully our engineers haven't.
The new dynamic engine mount system.
Adding to driving dynamics: the
dynamic engine mount system
is available as an option in the
911 GT3 and is standard in the
911 GT3 RS. This electronically
controlled system minimises
noticeable oscillations and vibra-
tions in the whole drive system,
particularly the engine.
Chassis
The engines in the 911 GT3
models are bolted to the body
using two mounts. According to
Newton's law of inertia, a body
will continue to move in a uniform
straight line unless it is made to
change its direction by a force act-
ing upon it. Put more simply: when
you are driving into a bend, the
vehicle will follow your steering
but, at first, the mass of the engine
won't. This means that the rear
of the vehicle is pushed outwards
after a time lag because of the
inert forces from the engine's mass
acting on it.
The dynamic engine mount system
minimises this effect. The steering
angle, longitudinal and lateral
