Acura's mid-size sedans get merged into one for the 2015 model year, as the TL and the TSX become the new TLX sedan.The TLX was shown at the 2014 Detroit auto show as a prototype, a
lightly veiled version of the sedan due in Acura showrooms this fall.
The new car adopts some of the cues found on the larger RLX sedan, with
emphatic use of LED headlights and exaggerated fenders that house the
20-inch wheels of the concept car. LED lights also underline the
sideview mirrors.
Two distinct models offer divergent faces to the TLX range: a base
model, powered by a 206-horsepower, 2.4-liter four-cylinder engine; and a
higher-tier 3.5-liter V-6 option, good for 290 horsepower. Direct
injection and variable valve timing help both engines make the most of
their displacements.
The four-cylinder is coupled to a new eight-speed,
dual-clutch transmission with torque converter that smooths out all of
the jerky tendencies of a typical dual-clutch, while simultaneously
delivering fast, crisp shifts whether driving with spirit or cruising
with ease. The V-6 engine is paired with a nine-speed automatic
transmission, operated by a pushbutton interface in the center console.
While the extra
gears in the nine-speed sound impressive, in our time with the car we
found it to be a hesitant, pokey gearbox often late to the party when
quick acceleration was called for, such as when merging with fast
traffic.What then, is the advantage of the V-6 and nine-speed combo over the
four-cylinder with the eight-speed dual-clutch? Available all-wheel
drive.
Both the four-cylinder and V-6, when equipped with front-wheel drive,
get the ability to steer the rear wheels slightly via actuators, a
setup like that on the luxury RLX four-door, a system Acura calls
Precision All-Wheel Steer, or P-AWS. With Super Handling All-Wheel Drive
(SH-AWD), the TLX has torque-vectoring control to assist with
cornering. The TLX is be fitted with a four-mode driver-selectable
system that alters steering weight, throttle response, and shift mapping
to give it a more comfort- or sport-oriented feel. In our experience driving the TLX, the front-drive four-cylinder is
by far the most rewarding driver's car in the lineup, with an
immaculately balanced chassis and very settled, predictable handling.
The V-6 feels heavy and a bit more sluggish when cornering, a feeling
exacerbated by the sluggish powertrain.
While it also replaces the Euro-Accord TSX, the new TLX is sized more
like the outgoing TL. It rides on an identical wheelbase of 109.3
inches, but is shorter overall, at 190.2 inches (down nearly four).
Interior space has stayed in the same range as that in the TL, good for
five passengers. The cabin is also much more quiet, leveraging active
noise cancellation for nearly silent driving up to 70 mph.
The 2015 TLX hasn't yet been crash tested by the IIHS or NHTSA, but
should perform well on safety, based on recent Acura scores and a slew
of equipment including lane keeping systems, adaptive cruise control,
and blind-spot monitors.
