| The Bottom Line | The 2010 Porsche Panamera delivers a spectacular driving experience in a surprisingly practical car, while modern cabin tech satisfies navigation and entertainment. | With a powerful yet efficient engine and high-tech suspension, the pricey 2012 Porsche Panamera Turbo S delivers near-supercar performance, but the cabin electronics fall short of cutting-edge. | Despite some very slight issues, the Audi A6 is a tech powerhouse, a comfortable sedan with a powerful, efficient engine and the most advanced navigation system available. | Mercedes-Benz bolsters its reputation for luxury with the 2012 CLS550. A powerful and efficient engine propels this sleek ride, and there are a number of advanced driver-assistance features. | The 2013 Lexus GS 350 makes for a convincing high-tech cruiser. With the F Sport package, it has some real performance chops, although it falls short of a BMW M or Mercedes-Benz AMG. |
