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. Driving for RTR in 2007 is Peter Cunningham, Pierre Kleinubing, Brandon Davis, Nick Esayian, and Kuno Wittmer. Acura won the Manufacturers’ Championship of the Speed World Challenge Touring Car class in 2006, running both RSXs and TSXs. TSX drivers finished in 3rd and 4th in the Drivers’ Championship.
The 2006 model year TSX’s powertrain is comprised of a 2.4-litre inline four-cylinder engine, a six-speed manual transmission (which features a magnesium casing, to reduce weight), and a front wheel drive layout. A five-speed automatic transmission is optional and does not incur extra cost in the U.S. based on MSRP. Such is not the case in Canada.
The engine, the K24A2, is 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 features intelligent variable valve timing i-VTEC and produces 205 horsepower (150 kW) in this iteration.
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.
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, and luxury features such as an auxiliary MP3 player input and Bluetooth-compatible HandsFreeLink.
In 2007, besides a new TPMS (tire pressure monitoring system) and an improved electronic rear view mirror, the TSX is the same.
The 2008 model year brings a few additional features and a new colour to the TSX.
In testing conducted by the United States based Insurance Institute for Highway Safety (IIHS), the Acura TSX received an overall rating of Poor rear crash protection, an overall rating of Good for frontal offset testing, and an overall rating of Acceptable for side impact testing.
