The Lexus S450 is the world’s first luxury car to go into production employing a petrol-electric hybrid powertrain. This is a fantastic idea of innovation especially with the ever rising cost of fuel prices, it apparantly cuts the price of fuel for the user by a quater if not more, The GS450h also emits 30 grams less of climate changing carbon-dioxide per kilometre, which is a massive kay point as global warming is becoming such a major issue in our current time. The Lexus isnt cheap coming in at approximatly 100,00 american dollars, but I think its leading the way for all car manufacturers and industry. Imagine how much cheaper it would be to run your car on a quarter if not less of the price. Performance isnt an issue either the engine kicks in at certain rev points for those steep hills or important quick takeovers. However the engine only kicks in when needed and thus is fantastic for those long cruising journeys at a steady speed which will save you loads on fuel price and consumption.
