With a new turbo V6 developed exclusively for Type S models.
The Acura TLX is a pretty smart sedan, but it's lacking a little something. That something is on the way though, and it's called the TLX Type S. We already know a whole lot about the car, including that it will be arriving with the most powerful Type S engine yet, a powerplant that it will share with the MDX Type S SUV. It's a 3.0-liter turbocharged V6 and is said to incorporate technologies from the NSX supercar. With 355 horsepower and 354 lb-ft of torque on tap, the TLX Type S becomes "the best performing Acura sedan ever." Acura has released a video highlighting the development of this engine, and it's quite interesting.
Acura says that it is sharpening its focus on "Precision Crafted Performance", which it aims to showcase through features like the new Type S V6 turbo (that was developed exclusively for the Type S versions of the TLX and MDX) and Super Handling All-Wheel Drive, a system with true torque vectoring for outstanding handling. You also get a 10-speed automatic that has been tuned for quicker shift speeds, but the engine remains the highlight of the package. It boasts enhanced crank rigidity, low-profile cylinder heads, a forged steel crankshaft, and forged steel connecting rods, as well as a twin-scroll turbocharger for a great balance of good response and strong top-end power.
To further aid throttle response, the exhaust manifold is cast directly into the cylinder head, while variable valve timing on both the intake and exhaust camshafts helps improve torque. Maximum boost is 15.1 psi, and with peak torque available from as low as just 1,400 rpm, overtaking will be a breeze in any of the ten gears. The TLX Type S comes with an active exhaust too, adopted from that of the NSX. In Comfort, the valves are closed and remain so until 4,000 rpm. In Normal, the valves are open at startup and close once the car is in gear. In Sport, the valves are always open besides during cruising, while Sport+ leaves them open at all times.
The car arrives at dealers tomorrow with an MSRP of $52,300 while spending another 800 bucks will give you the High Performance Wheel and Tire package.
