The Acura TSX is a compact executive car that was manufactured by Acura from 2003 to 2014. Introduced in April 2003 as a 2004 model, it was sold only in the United States and Canada, but since the 2009 model year it has also been available in Mexico. It is also sold in Guam and Puerto Rico. It was sold in North America under the Acura luxury marque, where it filled the gap as Acura's 4-door, entry-level sedan when the Integra sedan was discontinued in 2001 (1996 in Canada since the EL was the Integra sedan's replacement there). The TSX would also eventually replace the Acura RSX in the US (which in turn succeeded the Acura Integra coupe). From 2008 until 2013, the TSX was the smallest vehicle in the Acura model line, other than the Civic-based CSX (and the preceding 1.6/1.7EL) sold only in Canada. In 2013, the smaller ILX was introduced in both the United States and Canada, based upon the Civic platform (replacing the CSX in Canada). All TSXs were built in Sayama, Saitama, Japan.
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.
2005 was the second year of the TSX and Acura updated it with XM Satellite Radio, a four-way power passenger seat and illuminated the steering wheel-mounted audio and cruise controls. Along with the slight tweaks to the engine in 2006, interior tech features were also added, including a Multi-information Display (MID) in the instrument panel, and luxury features such as a two-position memory for the driver's seat adjustments which adjusted according to which of two keys were being used, auxiliary MP3 player input and Bluetooth-compatible HandsFreeLink (for cellular phones). The Bluetooth HandsFreeLink system operates through voice control, where the user speaks when the HandsFreeLink button is pressed. Six different phones can be paired up to the HandsFreeLink system.
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.
The K24A2 engine used in the TSX was related to the engine in the Honda Accord (7th generation), the Honda CR-V, and the Honda Element. The K24A2 featured intelligent variable valve timing (i-VTEC) and produced 200 hp (149 kW) in this iteration. Another feature 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 cams in its three rocker design.
For the 2006 model year, the K24A2 was updated to produce 205 hp (153 kW). The diameter of the throttle body and intake valves were slightly increased, along with the cam duration and valve lift.
The redesigned 2009 Acura TSX made its debut at the New York International Auto Show on March 20, 2008 before going on sale on April 24. In terms of size, the TSX is larger than its predecessor with 3.0-inch (76 mm) greater width, a 2.6-inch (66 mm) wider track and a 1.3-inch (33 mm) longer wheelbase, and the length grew by 2.4 inches (61 mm). Curb weight increased by approximately 100 to 150 lb (45 to 68 kg).
Making its debut on the new TSX is Honda's Advanced Compatibility Engineering body structure, which is designed to reduce accident impact on occupants. In the United States, the 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; in Canada this configuration is known as the "Premium Package" as there is a base trim available with the four-cylinder TSX that has cloth seats and halogen headlights, and without the USB connector, memory seat function, and fog lamps. 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.
Acura also added a "Sport Wagon" version of the TSX in fall 2010 as a 2011 model. The wagon is available with the I4 engine and 5-speed automatic.
The 2010 model year TSX added an optional 3.5L 280 hp V6 engine, shared with the Acura TL. It comes standard with the five-speed automatic transmission with paddle shifters and 18-inch alloy wheels, and is available in either Premium or Technology trims.
For the 2011 model year, the TSX received a facelifted grille with horizontal slots.
For the 2012 model year, Acura introduced an all new Special Edition model. The exterior features a more aggressive front spoiler giving it a sporty look, reminiscent of their old sports coupe, the RSX. Other cosmetic upgrades include a rear bumper fascia, side sills, and a "Special Edition" badge on the trunklid. In the cabin, Acura made sport-minded appointments including suede seat inserts with red backing. There is red stitching on the shift knob, seats, and steering wheel, along with red ambient lighting featured on the gauge cluster, overhead lighting, and footwell lighting. The pedals have also been upgraded to aluminum.
In late 2013 Honda announced that the TSX would be replaced with the Acura TLX sedan and that they will discontinue sales of the TSX model in 2014.
The new TSX uses a base engine similar to that of the previous TSX. The engine is a 2.4-litre in-line 4-cylinderengine reaching 201 hp (150 kW) and 172 lb⋅ft (233 N⋅m) 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 became available in the 2010 Acura TSX. The TSX V6 is only available with the 5-speed automatic transmission.
Acura TSX Sportwagon
2011 TSX Sport Wagon is a version of Honda Accord Tourer, with 60.5 cu-ft of rear cargo area (with rear seats folded down; 25.8 cu-ft with the seats up), rear seats with 60/40 fold-down design.
The vehicle was unveiled in the 2010 New York Auto Show. The Acura TSX Sportwagon is powered by the same 201-horsepower Honda K engine 2.4L DOHC inline four-cylinder engine and features the same four-wheel independent sports suspension as the sedan.
US model of 2011 TSX Sport Wagon went on sale in 2010-12-21 with a base price of $30,960 USD ($34,610 USD with Technology Package). Early models include 2.4L I-4 engine, Sequential SportShift 5-speed automatic transmission.
Acura Canada decided not to sell the TSX Sport Wagon until an unspecified later date, citing market conditions as the reason for the delay. The wagon variant was ultimately never sold in the Canadian market.
Changes to 2012 TSX Sport Wagon include a compact tire repair kit that allows for a significantly larger underfloor storage area.
2012 TSX Special Edition

The Insurance Institute for Highway Safety (IIHS) found the 2009-11 TSX to have an overall driver death of 7 deaths per million registered years, the 2nd lowest of midsize four-door cars, and both single-vehicle crash death rate and rollover death rate of 0.
In November, 2004, the TSX earned Consumer Reports' "Recommended" mark; in addition they named the car "Best Overall" in tests of four sporty sedans. In April 2007, the magazine rated the used TSX a "Good Bet."
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.
