Toyota demos Prius' proximity notification system, touts 'futuristic' purr (video)
Silence may be a virtue under most circumstances, but not when you're driving around a leafy, residential neighborhood in your Toyota Prius. That's why the manufacturer came out with its very own vehicle proximity notification system last year -- a "futuristic," underhood noisemaker designed to alert pedestrians and the visually impaired to the plug-in's presence. Now, Toyota has offered more details on its safety system, in a freshly released demo video starring the 2012 Prius V. The car's artificial engine noise, as the company explains, only kicks in at speeds below 15 miles per hour, allowing it to broadcast its audible heads-up across parking lots or other low-speed zones. The sound itself, meanwhile, emanates from external speakers and consists of a blend of high and low frequencies that won't be by muffled by background noise or physical obstacles. The vehicle's pitch shift technology also enables the tone to rise in pitch as the car speeds up and to fall as it slows down, giving others an idea of how fast it's approaching. Accelerate past the break to see the full video for yourself, while John Kerry nods in silent approval.
Hands-on with Toyota's Prius plug-in hybrid (video)
Yesterday we attended Toyota's Green Drive Expo where we were given the opportunity to take the production version of the Prius plug-in hybrid (PHV) -- and its smorgasbord of technology -- for a spin. We spent a couple hours driving interfacing with the computers aboard the Advanced model, which besides being outlet-friendly, includes some unique features within the Prius lineup. Explore our gallery below, and hit the break for our impressions and hands-on videos with the latest incarnation of Toyota's iconic vehicle.%Gallery-134091%
