The 2004 model year TSX's powertrain is comprised of a 2.4-L inline four-cylinder engine (automotive.com, 2003), a six-speed manual transmission (Engine Power, 2003), and a front wheel drive layout (automotive.com, 2003).
The TSX is based on the European and Japanese CL-series Honda Accord. However, the TSX has a restyled interior and different suspension tuning.
The engine, the K24A1, 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 K24A1 features intelligent variable valve timing and produces 200 horsepower (150 kW) in this iteration.
The TSX comes with either a 5-speed sportshift automatic or a 6-speed manual. The manual features a magnesium casing, to reduce weight.
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.
