The TLX is Acura's best sedan, but it still doesn't quite measure up to the competition. It's available with either a four- or a six-cylinder engine; all-wheel drive is only available with the V6. The 2.4-liter uses an eight-speed automatic that delivers quick, direct shifts and contributes to the very good 27 mpg overall. The V6 is a gem, with plenty of power, but its nine-speed automatic shifts roughly and uses an annoying pushbutton shifter. Handling is responsive, but not sporty, although the ride is quite comfortable. The cabin is quiet, but rear-seat room is so-so. Featuring two different screens, the infotainment system is unintuitive to use. A generous roster of advanced safety systems includes front-collision mitigation, lane-departure warning, lane-keep assist, adaptive cruise control, and blind-spot monitors. A 2018 update makes the AcuraWatch suite of safety equipment standard, as well as adding luxury features and tweaking the suspension and steering.
