The Acura TLX is an upcoming luxury sport sedan that is due to replace both the TL and TSX models in Acura’s sedan range. With the TLX, the luxury brand will have a step-up model from the ILX that will factor as both sportier and more luxurious—as well as one that will compete against the BMW 5-Series, Jaguar XF, Lexus GS, and the Cadillac CTS in size and purpose.
The TLX’s overall length is around 190 inches, while its 109.3-inch wheelbase is carried over from the current TL Although we’re not completely sure about details for the production 2015 Acura TLX model, the TLX Prototype has been shown with big 20-inch wheels, plus LED headlights with integral LED running lamps, and accent lights at the bottoms of the mirrors.
Two different engines will be offered on the TLX: a 2.4-liter direct-injection in-line four, with an eight-speed dual-clutch automatic transmission, and a 3.5-liter V-6 with a nine-speed automatic transmission. The V-6 gets Variable Cylinder Management, which will allow it to run on just four cylinders during light-load conditions. Neither power nor fuel economy figures are out for the TLX at the time of writing—it’s officially only been shown as a ‘prototype’ at this stage—but the automaker promises ratings “at the top of the midsize luxury sedan class.”
Front-wheel-drive versions of the TLX will 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 tucks the rear wheels in a way that will either add to maneuverability at low speeds or aid stability at higher speeds. All-wheel-drive versions will also be offered (with the V-6), and those will pack a new lighter version of the brand’s Super-Handling All-Wheel Drive (SH-AWD) system with new torque vectoring. Expect this system to yield true sport-sedan dynamics in addition to all-weather confidence, as it has in the outgoing generation of the TL.
Dedicated driving modes will allow you to cater the driving experience to expectations; 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 controls, and the control logic for the all-wheel drive or rear-wheel steering.
Active Noise Control will help keep the cabin quiet; so will new body-sealing and sound-insulation measures. And inside, based on our observations of the prototype at several auto shows this past winter, the TLX looks just as roomy as the TL—in other words, still still a bit roomier in back than its German sport-sedan rivals.
An array of accident-avoidance technologies, some of them previously offered on the RL (or RLX), also now move down into the TLX. Collision mitigation braking, forward collision warning, lane departure warning, lane keeping assist, and adaptive cruise control, and a low-speed follow/blind-spot inducator (each with their acronyms), will all be available on top-of-the-line versions. Acura is already anticipating a top five-star Overall rating from the federal government, as well as Top Safety Pick+ status from the Insurance-funded IIHS.
The Ohio-built 2015 Acura TLX will arrive at dealerships later this year.
