Overview
The 2004 model year TSX’s powertrain consisted of a 2.4-litre inline four-cylinder engine, a six-speed manual transmission (which featured a magnesium casing, to reduce weight), and a front wheel drive layout. A five-speed semi-automatic was optional and did not incur extra cost in the U.S. based on MSRP; however such was not the case in Canada. The TSX’s suspension setup of a double wishbone front and a multi-link in the rear was especially tuned by the Honda engineers to maximize handling and cornering speed. [citation needed]
2005 was the second year of the TSX and Acura updated it with XM Satellite Radio, heated door mirrors, a four-way power passenger seat and illuminated the steering wheel-mounted audio and cruise controls. In 2006, the TSX was updated with slight tweaks to the engine (adding 5 hp); a sportier exterior styling featuring a slightly new front and rear treatment, standard side skirts, and standard, integral fog lights; and restyled wheels. State of the art interior features have been added, including a Multi-information Display (MID) in the instrument panel, more standard safety features,[citation needed] and luxury features such as an auxiliary MP3 player input and Bluetooth-compatible HandsFreeLink. In 2007, a new Tire Pressure Monitoring System and an improved electronic rear view mirror were added, and the 2008 model year brought a few additional features and a new colour to the TSX.
Engine
This is the Honda Accord sedan sold in Japan and in Europe. It is the basis for the Acura TSX.
The K24A2 engine used in the TSX was related to the engine in the Honda Accord (7th generation), the Honda CR-V, the Honda Element, and a smaller version in the Acura RSX and RSX Type-S. The K24A2 featured intelligent variable valve timing (i-VTEC) and produced 200 horsepower (150 kW) in this iteration.
Since 2006 model year, the Acura TSX has used a 2.4-litre in-line 4 cylinder engine making 205 hp (153 kW) SAE J1349 net. The advertised increased power figures on previous models were over-estimated by +10 hp (7 kW), the actual power rating is 205 hp (153 kW). SAE J1349 is a third party program designed to eliminate ambiguities that allowed engine makers to cite power and torque ratings higher than the engine’s actual capabilities. The most significant changes to the motor are described as follows:
On the intake side of the TSX engine, the diameter of both the throttle body and the intake duct were enlarged to increase induction flow rate from 95 liters per second to 110 liters per second. In addition the diameter and shape of the intake valve were enhanced to help increase intake flow by 16 percent and the high RPM cam profile for the intake cam was modified to provide increased intake valve lift and duration. In addition, a ventilation passage was machined into the engine block to reduce pumping friction by increasing air flow between cylinders.
Also significant of the i-VTEC system on the TSX and RSX-s was that unlike other Honda K-series motors variable timing was used on both the intake and exhaust ports in its three rocker design.
In testing conducted by the United States based Insurance Institute for Highway Safety (IIHS), the Acura TSX received an overall rating of “Good” for frontal offset testing, an overall rating of “Poor” rear crash protection, and an overall rating of “Acceptable” for side impact testing.

Overview
The fully redesigned 2009 Acura TSX made its debut at the 2008 New York International Auto Show on April 11, 2008. In terms of size, the 2009 TSX is larger than its predecessor. The new TSX has a 3.0-inch (76 mm) greater width, a 2.6-inch (66 mm) wider track and a 1.3-inch (33 mm) longer wheelbase than the current TSX; additionally, the length grows by 2.4 inches (61 mm). Acura is also planning on adding a wagon version of the TSX in Fall 2010 as a 2011 model
The 2009 TSX comes standard with luxury features like leather seat upholstery, dual-zone climate control, power driver’s seat with memory, sunroof, Xenon headlights, and adds a USB port music interface. The TSX has an optional technology package, which includes a navigation system real-time traffic and weather, and a 10-speaker premium sound system with DVD-audio capabilities. Also making its debut on the new TSX is Honda’s Advanced Compatibility Engineering body structure, which is designed to reduce accident impact on passengers. The 2009 TSX was released on July 16, 2008.
2008 Honda Accord (JDM and European model)
In the IIHS crash tests, the 2nd generation TSX received Good overall marks in both front and side impact crash tests and the Good score in all 14 measured categories. The IIHS gave the TSX its “Best Pick” accolade.
The fall of 2010 will see the introduction of a sport wagon variant of the 2011 model.
Engine
2008 Honda Accord (JDM and European model)
The new TSX uses a base engine similar to that of the 2008 TSX. The engine is a 2.4-litre in-line 4 cylinder engine reaching 201 hp (150 kW) and 172 lbft (233 Nm) torque. While the rated power of the new TSX engine is 4 hp (3.0 kW) lower than that of the 2008 model, Acura says the new engine distributes power across a much wider rpm range, which along with the increased torque, provides an increased feeling of power for the driver. The transmission choices remain 5-speed automatic and 6-speed manual, though the automatic version now comes with steering-wheel paddle shifters for optional manual shifting.
The TSX was slated to receive a high performance 2.2-litre i-DTEC clean turbodiesel engine in the 2010 model year; however, it was later announced that Honda had abandoned its plans to bring diesel engines to the U.S. and Japan in favor of hybrid gasoline-electric powertrains. Instead, a 280 hp 3.5-litre V6 will be available in the 2010 Acura TSX. The TSX V6 will only be available with the 5-speed automatic transmission.

Racing
Realtime racing prepares a factory TSX and RSX to compete in the Speed World Challenge Touring Car series. The factory TSX is refashioned to be stiffer and lighter, and includes motor work with raised compression, and a custom built sequential transmission. Acura won the Manufacturer’s Championship for the Touring class in 2005 with the RTR TSX, as well as the Driver’s Championship for Peter Cunningham. Acura returned in 2006 and won the Manufacturers’ Championship of the Speed World Challenge Touring Car class for the second year in a row, running both RSXs and TSXs. TSX drivers finished in 3rd and 4th in the Drivers’ Championship. More success followed as Pierre Kleinubing won the Championship in 2007, and Peter Cunningham took it in 2008. Driving for RTR in 2009 is Peter Cunningham, Pierre Kleinubing, Toby Grahovic, Kuno Wittmer, and Jeff Courtney.
