The existing EU Noise test is flawed: this is what happens:
The current noise test for passenger cars, as set out in EU Directive 92/97 as amended, consists of driving the vehicle into the test area at a speed of 50 km/hr and then accelerating at full throttle through it past a microphone. The microphone is placed at a set distance from the line of travel and it measures the maximum level of noise reached which is then compared to the limit value to determine whether the vehicle passes or fails.
The test area is surrounded by an open area to avoid sound reflections and the road surface is carefully constructed to a set standard to ensure consistency of results.No performance car is going to make much noise if full throttle is applied at 30mh in top gear. Which is how Mogs, Jags and others can make so much noise at high revs.
There is a new test on the way that shouldn't cause anyone any real problems: this is a good summary.
Noise As tiime goes by we will probably see more use of "sport" modes, so that the car is quiet in normal mode and intresting in sport mode, with the use of sport mode prohibited in urban areas.
I suspect all 4 wheel Mogs are already compliant with the next round: the Plus 8 is very quiet, quieter than the Roadster, at all normal speeds: it is only when the revs get above about 4000 does the howl start...and then it just gets better and better...!!
