The 2012 Chrysler 300 has rear-wheel drive and a roofline that favors design over utility--so it's no big surprise that compared to other sedans of this size, the 300 isn't quite as roomy in back as other large front-drivers like the Toyota Avalon or even Volkswagen Passat.
The front seats have good bolstering and great head room, even when a sunroof is fitted, and we like the front seats' softer-skinned leather and nice compromise between wide cushions and side bolstering. As for the back seat, it you might need to duck your head to get in, and knee room is limited, but once back they feel like spacious quarters--and thinner roof pillars and larger glass areas brighten up the interior.
You'll find plenty of places to hide things in the 300's cabin. The cupholders hide under a roll-away tambour; the center console hides a usefully deep well, and there's a nicely sized bin in the console ahead of the shifter. All the doors have molded-in bottle holders. In the trunk, 16.3 cubic feet of space will hold plenty, even if it's not as big as the titanic 20-cube trunk in the Ford Taurus.
While the textures all feel swell, the rubberized dash cap has a gummy grip that lint loves to call home--detracting slightly from the modern-Sinatra vibe that the 300 (especially the all-black versions) toss off casually.
The 300 family has advanced by leaps and bounds in refinement and cabin isolation over the past couple of model years. In V-6 models, there's only a semi-pronounced, midrange thrum emanating from the V-6 engine, blunted by thicker glass but still noticeable. You'll also hear the burble and thrum of V-8 engines, but in any of these models road and wind noise are well shut out.
