The Acura TLX is a new offering from Honda's luxury arm,joining the lineup as of the 2015 model year. A combined replacement for the TL and TSX mid-size sedans, the TLX puts Acura's four-door efforts on a more solid footing. The new car fits in well with a lineup that includes the ILX compact sedan and the larger RLX. (It also somewhat rationalizes the company's naming scheme, with all models now using three-letter titles ending in X.)
Competition for the TLX comes from cars like Buick's Regal and LaCrosse, the Lincoln MKZ, the Volvo S60, and the Lexus ES.

The TLX’s overall length is around 190 inches, which is close to the former TSX's measurement; its 109.3-inch wheelbase is carried over from the TL. Styling is a handsome update on the themes from the latest Acura products, neither terribly exciting nor offensive, and no longer plagued by a beaky grille.
The TLX is offered with a choice of two engines. Base models come with a 2.4-liter direct-injected four-cylinder making 206 horsepower and paired with an eight-speed dual-clutch automatic transmission. For a little extra, buyers get a 3.5-liter V-6 good for 290 hp and mated to a ZF-sourced nine-speed automatic. V-6 versions also make use of Variable Cylinder Management, which can shut off three cylinders to save fuel under lighter loads, such as when cruising on the highway.
Front-wheel-drive versions of the TLX get one noteworthy piece of technology handed down from the top-of-the-line RLX sedan: the Precision All-Wheel Steer (P-AWS) system, which turns the rear wheels slightly in a way that will either add to maneuverability at low speeds or aid stability at higher speeds. All-wheel drive is available on V-6 models, featuring a new, lighter version of the brand’s Super-Handling All-Wheel Drive (SH-AWD) system with rear-axle torque vectoring.
Dedicated modes allow the driver to cater the driving experience to their desires. As part of a so-called Integrated Dynamics System (IDS), the TLX gets Econ, Normal, Sport, and Sport+ settings, with each one affecting power-steering calibration, throttle response, transmission shifts, Active Noise Control settings, climate control operation, and the calibration of the all-wheel drive or rear-wheel steering system.
Active Noise Control helps keep the cabin quiet, as do new body-sealing and sound-insulation measures. And inside, the TLX is just as roomy as the TL—in other words, still a bit roomier in back than the German sport sedans in this size class.
An array of accident-avoidance technologies, some of them previously offered on the RL (and now the RLX) and MDX, also now move down into the TLX. Collision-mitigation braking, forward-collision warning, lane-departure warning, lane-keeping assist, adaptive cruise control, and a low-speed follow/blind-spot indicator (each with their acronyms), will all be available on top-of-the-line versions. The TLX has achieved a top five-star overall rating from the federal government, as well as Top Safety Pick+ status from the insurance industry-funded IIHS.
