What is it? The second-generation Acura RDX tweaks the formula, but it remains the premium rendition of the Honda CR-V. Riding on a longer wheelbase, the redesigned five-seat SUV aims to elevate its luxury accoutrements, led by a roster of infotainment features, active suspension, and enhancement safety systems.

What is new or notable? Gone is the turbocharged four-cylinder engine. In its stead, Acura has fitted the RDX with a stronger 3.5-liter V6 with 273 horsepower, up 33 horses over the outgoing model. The engine is fitted with a six-speed transmission. The all-wheel-drive system has been replaced with a lighter, less-costly system. All told, the RDX promises improved fuel economy, with the FWD variation targeting 20 mpg city, 28 mpg highway. 

When will it be available? Spring 2012.
