March 24, 2005 Lexus has unveiled another luxury hybrid vehicle. The 2007 Lexus GS 450h is the world's first hybrid luxury sedan and the first full hybrid vehicle with a front engine and rear wheel drive. With the world's first gas/electric hybrid-powered luxury SUV, the RX 400h, going on-sale next month, the announcment of the GS 450h indicates an acceleration of Toyota's hybrid program, with availability slated for just over 12 months from now - the second quarter of 2006. A completely new Lexus Hybrid powertrain was created to power the new 450h. The system combines a 3.5-liter V6 engine with a high-output, permanent magnet electric motor—all driving the rear wheels. Combined power output will be well in excess of 300 horsepower, with zero-to-60 acceleration in less than six seconds.
