Featured Vehicle

First Generation

The Acura TSX was introduced at the 2003 North American International Auto Show as a production model. The 2004 model year TSX's powertrain consisted of a 2.4-liter inline four-cylinder K24A2 engine which produced 200 horsepower, a six-speed manual transmission (which featured a special casing, to reduce weight), and a front wheel drive layout. A five-speed automatic transmission was a no-cost option in the U.S. based on MSRP; however, such was not the case in Canada.

In 2006, the TSX was updated with slight tweaks to the engine (adding 5 hp with an increase from 200 hp to 205 hp); a sportier exterior styling featuring a slightly new front and rear treatment, standard side skirts, and standard, integral fog lights; and restyled wheels.

In 2007, Tire Pressure Monitoring System and an improved electronic rear view mirror were added, and the 2008 model year brought a new color option.

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.

Second Generation

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.

For the United States, Acura also added a "Sport Wagon" body style 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.
