Acura fired a BB gun across the bow of BMW, Mercedes and Toyota—introducing its second-generation TSX luxury sedan—aimed to compete with models such as the Mercedes C class and Lexus IS lines. The 2.4-liter engine packs 201 horsepower and 179 pound-feet of torque, but Honda, having earned EPA's Tier II level of efficiency, claims better fuel economy than that of its predecessor. And it's wired. The optional "Technology Package" includes a voice-activated navigation system, realtime traffic updates and weather reports, plus a rear-view backup camera and a 10 speaker sound system. "This is the year of the sedan," they told us. If you've seen the new Honda Accord that debuted in the fall, you'll recognize similar design cues in the TSX. And if you like the new Accord, this is a nice step up.
