Acura Explains The Thinking Behind the TSX Type S, Detailed Engine

The 2021 Acura TLX Type S is now shining in showrooms nationwide, hoping to catch the eye of those who still remember that the brand once produced several really good performing vehicles. .. It seems to have been built under a similar philosophy, especially trying to regain the magic of TSX, which the world knew as a fun version of the Honda Accord.

Instead of focusing on ridiculous levels of power and excessive attitude, Acura sought to provide a balanced and classy luxury car that could be scrambled like an egg. Earlier descendants of this idea were about 200 horsepower, but the TLX Type S produced a much thicker 355 horsepower and 354 lb-ft torque, to drive that point home now that it was recently sold. Dropped some additional marketing material on.

TLX’s 3.0-liter 24-valve DOHC V6 and single twin scroll turbocharger developed by a team of Japanese and American engineers in charge of the Honda Civic Type R and Acura NSX. Combined with a 10-speed automatic, this unit borrows a lot from the company’s familiar 3.5-liter V6, but tolerates a fair amount of abuse and has been modified to fit snugly in the engine bay. I will.

From Acura:

Many engineering steps have been taken to ensure the compact size and thinness of the new engine, and it now fits in the TLX engine room. This includes the placement of a turbocharger adjacent to the engine above the transmission and the use of a thin cylinder head. The individual cam bearing caps have been replaced with caps built directly into the valve cover itself, lowering the engine height and reducing the number of parts. The fully assembled engine is 8mm shorter than the naturally aspirated 3.5-liter V6 engine.

The Type S Turbo V6 features a rugged rotating assembly that meets the demands of superior performance and durability, and features a high stress forged steel crankshaft and forged steel connecting rod. To reduce emissions, the upper piston ring carrier of the piston is high density Ni resist cast iron with excellent wear properties and excellent sealing.

There was also a lot of talk about optimizing turbochargers, exhaust systems, and catalytic converters in ways designed to manage heat in a more environmentally friendly way. But it’s incredibly boring and unlikely to be of interest to anyone buying a performance sedan. The important things are: Turbo boost starts early, peaks at 15.1 psi, and delivers up to 354 lb-ft of torque at 1,400 rpm. ..

The engine assembly is complete in Anna, Ohio, and the unit is to be paired very well with TLX’s upgraded suspension and “Super Handling All Wheel Drive” system. Acura also chose to equip the exhaust with a butterfly valve that allows the driver to adjust the enthusiasm of the sound emitted through several drive modes. These choices also change the throttle response, steering input, shift program, suspension damping, torque vectoring, and even the appearance of the vehicle’s interior display.

Despite its innovation, nothing seems to be at the forefront of performance when it comes to cars, which are electronically limited to 155 mph. But if the sedan is clearly designed to be a luxury car first and foremost, that’s generally fine. No one expects the TLX Type S to mix regularly with the Mazda MX-5, Nissan 370Z, Mustang GT and BMW 3 Series on weekend track days. It is elegantly restrained, carries passengers in a respectable and reliable way, option Shake things with serious on-demand performance.

Stakeholders should be ready to drop $ 53,325 for the top trim TSX. But you’ll probably want to spend an additional $ 800 to get a high-performance wheel and tire package. This replaces the Pirelli Cinturato P7 tires with a set of aggressive P-zero and significantly lighter wheels, reducing unsprung weight by nearly 24 pounds from the car. Given that the TSX Type S tilts the scale at £ 4,221, I think it makes a significant difference at the limits.

Certainly there is A cheaper way to get more horsepower from a comfortable car.. However, Acura seeks to offer a relatively complete performance package that can provide comfortable and attractive handling all day long.We like what we’ve seen so far and are curious about how the models stack up Genesis G70 with V6, Road tests clearly target both European executive car seas, not just the sea.
