Sport/utility vehicles have come under fire recently (some literally...) for their size and inefficient fuel economy, though Toyota aims to change that image with the technology found in the SU-HV1. Featuring an SUV-optimized Hybrid Synergy Drive and electric four-wheel drive (E-Four), the SU-HV1 promises V-8 performance teamed with the fuel economy of typical compact cars. Underhood, the hybrid powertrain matches a 3.3-liter/240-hp V-6 gasoline engine to a 163-hp electric motor up front and another 24-hp motor at the rear wheels to deliver powerful performance with fuel efficiency and emissions twice as good as currently found in an SUV of equal displacement. An additional Advanced Vehicle Dynamics Management system coordinates the hybrid system with E-Four and Electronically Controlled braking for improved handling and stability.
