It's not so facile to hide 460 pounds, but the engineers and developers who worked at the Cambece Infiniti's latest sport sedan did an amazing job of managing the extra weight. A Sport package — featuring also 20-inch wheels, a sport-tuned suspension, performance tires and improved brakes — provides the Infiniti G37 convertible with an unexpected responsiveness and safety for a 1.9-ton automobile.

And even the base model in the lineup going on the road with standard 19-inch wheels manages its weight in an amazingly good manner, avoiding undulation under all but the most difficult driving conditions or excessive wallow .

Several convertible-specific options and technologies are available for the 2009 Infiniti G37, including Bose Open Air sound system with headrest-mounted speakers , an optional adaptive climate control system and standard pop-up roll bars, Cambece specified.
