Lexus announced a second luxury hybrid vehicle today in New York. The all-new GS gets the two-powerplant treatment this time and will produce 300 horses with a 0-60 time under six seconds. It is a 3.5 L V-6 matched with the electric motor that will produce the same horsepower as the GS430's petrol V-8. It's an interesting move for the company to offer both with similar performance gains. No mileage numbers are available but the press release says "Similar to the average 2-liter, 4-cyl. compact sedan."
