The Bottom Line: The 2007 Maxima ticks all the tech boxes, but does so without much style. Despite its new continuously variable transmission, Nissan's flagship is less efficient than it should be.

The Bottom Line: The 2007 Audi A4 handles great and is a joy to drive. Audi offers a full range of optional cabin technology, such as navigation and Bluetooth, although some of it falls a little short.

The Bottom Line: The 2006 Lexus IS 350 uses the highest-quality cabin electronics, and its strong engine and good handling make it a lot of fun to drive. At its relatively low price, it is one of the best values in a luxury sport car we've seen.

The Bottom Line: The 2006 Volkswagen Passat hits pretty well in a number of tech departments, with an innovative power train, safety equipment that includes active headlights, and a very nice sound system. But the car just won't play with the gadgets in your life.

The Bottom Line: The 2006 Audi S4 commands a hefty premium over the standard A4, and although the cabin gadgets are similar, the performance gain is worth it. We had some minor issues, but overall, this is a top tech car.
