You're a luxury car maker, and your top selling vehicle is a very good Crossover SUV. Sales threaten to stagnate, and you've got to move ahead with the times. How do you make a good SUV into an excellent SUV? Add a hybrid gas/electric drive system. That's just what the good folks at Lexus did with their 2007 Lexus RX 400h. The 2007 Lexus RX 400h carries a base price of $41,180 ($49,110 as tested), a 4 year/50,000 mile basic warranty, a 5 year/70,000 mile powertrain warranty and an EPA estimate of 32 mpg city/27 mpg highway. So, how well does the luxury hybrid SUV work on a day-to-day basis?
