Interior Sound Level
The Houston Rev It Up video sounds and positive responses
made me reach for my C&D comparo where at full throttle and idle the dBA readings achieved average and 70 mph cruising only 1 dBA higher than average. Of coarse it is the turbine like sound and free-reving that make it so enjoyable. Most of the engineering is to eliminate as much of the sound as possible. The engine rpm @ 60 mph in top gear is said to be 3100. Here are SIX technologies that deliver passenger comfort with low intrusion of vibration, wind noise, etc: 1.)ist time use of counter-rotating gear & dynamic balanced rotors. 2.)mode control panels on bottom of car 3.)straight (from side or top) line pwertrain layout 4.)lengthened engine & diff. mount spans (significant vs. RX7) 5.)no floor mount drive shaft support 6.)lengthened multi-link (5) rear to a six rubber mount stiff subframe based suspension. up front strong chassis subframe.
