The 2015 Acura TLX luxury sport sedan will make its debut at the 2014 New York Auto Show.
The TLX -- a successor to the TL -- will slot below the RLX and above the ILX in Acura's lineup.
Acura is counting on the TLX to jump-start its sluggish U.S. car sales, which fell 10 percent in 2013 and are off 21 percent year-to-date.
The TLX prototype was introduced at the Detroit auto show in January.
The TLX will be equipped with either the company's 2.4-liter four cylinder making about 200 hp, or a 3.5-liter V-6 engine making about 310 hp. Acura hasn't disclosed specific performance specifications.
The four-cylinder engine will be paired with an eight-speed dual-clutch transmission; the V-6 will be mated to the company's nine-speed auto.
Both engines will be offered with two- and four-wheel drive. All versions will get Acura's P-AWS (Precision All-Wheel Steer) system, and the V-6 models will get SH-AWD (Super-Handling All-Wheel Drive), which is 25 percent lighter than the last system.
Safety features will include collision mitigation braking system, forward collision warning, lane departure warning, lane keeping assist system, adaptive cruise control with low-speed follow and blind spot indicator.
Acura said the TLX "was designed to deliver vault-like quietness in all driving conditions, with major improvements in noise reduction through enhancements to body stiffness, body sealing and sound insulation, and the application of electronic active noise control."
The TLX is expected to go on sale this summer. More details are expected to be released during press days of the New York Auto Show starting on April 16.
