Twice the performance with half the energy consumption. [fimg=right]http://www.cleanmpg.com/photos/data/501/Prius_v_-_News2.jpg[/fimg]Wayne Gerdes - CleanMPG - May 20, 2011 The Harman GreenEdge Sound System is prominently featured in the 2012 Prius v coming to a dealership near you this fall. Harman is introducing its environmentally friendly and high-performance GreenEdge audio technology in the latest Toyota vehicles including the upcoming 2012 Prius v MPV. The new GreenEdge JBL audio systems in the 2012 Toyota Prius v delivers improved clarity, dynamic performance and with considerably lower power consumption – a dramatic advance in automotive audio system design. The GreenEdge enabled Harman audio systems provide benefits ranging from reduced system weight to reduced energy consumption. The system offers not only improved fuel efficiency or extended EV range but also higher Sound Pressure Levels and greater dynamic response at lower power output for superior in-car audio precision and finally enjoyment. GreenEdge technologies are engineered holistically to ensure that the speakers, amplifier, equalization and component placement work together as an efficient system. Three key elements comprise a GreenEdge system: High-voltage amplification High-efficiency loudspeakers Advanced signal processing. In the upcoming Toyota Prius v, the new GreenEdge JBL system uses a high-voltage amplifier that reduces the energy dissipated as heat in the electrical components, enabling higher voltage to be supplied to the amplifier circuitry while reducing overall energy consumption. At maximum volume, power consumption is reduced by 50 percent! The system’s eight loudspeakers feature a new highly efficient design that produces greater output for a given amount of input power. In addition, specially designed speaker lenses improve the sound coverage area. Active equalization and a set of advanced signal processing tools refine the sound by continually monitoring speaker performance and optimizing the amplifier signal for each dedicated speaker. 2012 Prius v w/ Harman GreenEdge Sound System Detail Just as CFL or LED bulbs provide equivalent lumens using lower wattage, a GreenEdge audio system produces higher output or Sound Pressure Levels, measured in decibels (dB), while consuming less power. This requires the use of an Equivalent Watts rating, based on the amplifier’s average efficiency factor – 5X for the new Prius v system. The resulting Equivalent Watts rating for this system is 600W (120 GreenEdge Watts x 5). This next-generation JBL audio system in the Prius v weighs one-third less than the current Prius system, and reduces power consumption by 50 percent at 98 dB Sound Pressure Levels, yet delivers life-like clarity, dynamic range and transient response. What’s more, the system actually reduces the electrical load on the Prius v drivetrain, helping to extend mileage capabilities. GreenEdge enabled JBL systems will be available on most Toyota vehicles as future models are launched. Real World Conclusions Having listened to the new Harman GreenEdge system, the old and poorly received JBL system from the second and third generation Prius can finally be put to bed as old talking points. The new technology and its output can finally be called worthy of a vehicle like the Prius v unlike the upgrade in previous Prius’ that were more of a wallet drainer than a high fidelity system as anyone with that upgrade already knows.
