Acura has unveiled its replacement for the outgoing TSX and TL sedans - the 2015 TLX - at the New York show.

As expected, the production TLX draws heavily from the look of the concept that debuted earlier this year in Detroit. Both feature sinewy character lines and Acura's "Jewel Eye" LED lamps, though the production model gets more restrained front and rear lower fascias. The TLX rides on the same 109.3-inch wheelbase as the TL but is 3.8 inches shorter overall.

A pair of sophisticated new transmissions make their debut in the TLX. Entry-level models, which utilize a 206-horsepower and 182 lb-ft of torque 2.4-liter four-cylinder, receive an eight-speed DCT automatic that features a dual-clutch design for quick shifts as well as a torque converter for refined low-speed operation. The step-up motor, a 290-horsepower and 267 lb-ft 3.5-liter V6, pairs with a nine-speed automatic.

Front-wheel-drive will be the standard configuration for both engines, while the V6 will be offered with a next-generation version of Acura's "Super Handling All-Wheel-Drive" that is 25 percent lighter than before. FWD models benefit from Precision All-Wheel Steer, which adjusts the toe angle of the rear wheels in order to increase both agility and stability.

Increased use of high strength steel, aluminum and magnesium contributes to a lower curb weight - Acura says that the FWD 3.5-liter V6 model weights 3600 lbs., or 145 lbs. less than a comparably-equipped TL. While the TLX is not yet officially EPA certified, fuel economy is estimated at 24/35/28 city/highway/combined mpg for the four-cylinder, while FWD and AWD V6 variants should be good for 21/34/25 mpg and 21/31/25 mpg, respectively.

A new Integrated Dynamics System lets the driver choose between four drive modes that adjust steering settings, throttle response, shift mapping, SH-AWD or PAWS control logic, and even Active Noise Control and HVAC settings.

Inside, the TLX combines Acura's dual-display screen setup with available premium furnishings like Milano leather and alloy and wood-grain accents. A push-button gear selector is standard in V6 sedans, while all models benefit from the automaker's latest AcuraLink connected car system and Siri Eyes Free.

On the safety front, the TLX debuts a Road Departure Mitigation system that warns the driver if the sedan begins to wander into an adjacent lane, and can apply steering inputs to get things back on course. A plethora of other high-tech safety features are also available, including a Collision Braking Mitigation system, Blind Spot Information, Lane Departure Warning, Forward Collision Warning, Lane Keep Assist System and a new Cross Traffic Monitor.

The TLX will be built at Honda's plant in Marysville, Ohio, and will hit the market for the 2015 model year.
