From Acura press: The TSX sports sedan complements the sporty TL and the luxurious RL. The TSX is positioned as a stepping stone to these established nameplates, providing luxury sedan buyers with an entry point to the Acura brand.
The front-wheel drive TSX was engineered and appointed to compete with Europe's best sedans in the sporty near-luxury segment (the European D segment). This segment includes cars like the Audi A4 and the BMW 3 Series.
In keeping with its European competitors, the TSX driving character is sharply focused on the sporty end of the scale. Its double-wishbone front and multi-link rear suspension has sophisticated geometry that helps the TSX corner flat and resist acceleration lift and braking dive. In addition, the TSX has P215/50R17 Michelin MXM4 V-rated tires, 4-wheel disc brakes, and an impressive arsenal of electronic driver aids including Vehicle Stability Assist (VSA) with traction control and an Anti-lock Braking System (ABS). A highly refined power rack-and-pinion steering system provides outstanding road feel that rivals the best Europe can offer. The takeaway for the driver is an ultra-competent entry luxury sports sedan that's immensely fun to drive.
The precise handling of the TSX perfectly complements its 200-hp 2.4-liter i-VTEC™ 4-cylinder engine. It is available with either a 6-speed manual transmission (with a lightweight magnesium case) or a 5-speed SportShift™ automatic that offers quick and precise gear changes.
Thanks to its i-VTEC® intelligent variable valve timing and lift, the engine provides a broad, useable powerband that's uncommon in a 4-cylinder engine, together with a stirring high-rpm power rush. The TSX engine, with its 7100-rpm redline is backed by 40 years of Honda international racing experience in Formula One, CART and Grand Prix motorcycles.
The TSX is a precisely engineered sports sedan that blends agility and handling with 5-passenger comfort. That delicate balance of attributes drove every aspect of development, including the selection of the powertrain. When it came to choosing a powertrain configuration for the TSX, the path soon became clear. A V-6 like that in the TL would deliver abundant power, but would increase the size and weight of the car, and move the TSX away from its sporting intentions. An in-line 4-cylinder, using the latest Acura technologies, would make for a lighter, well-balanced, more compact vehicle that put the emphasis on overall sporting performance and handling responsiveness.
Power for the TSX comes from an advanced 2.4-liter DOHC i-VTEC in-line 4-cylinder that builds on the technology found in the RSX Type-S sports coupe. With an i-VTEC "intelligent" valve control system that features Variable Valve Timing and Lift Electronic Control (VTEC) combined with Variable Timing Control (VTC), the TSX engine delivers formidable power, impressive fuel economy and very low exhaust emissions.
Despite its power output, the TSX engine is also very clean. With its rear-mounted exhaust layout, close-coupled catalyst and advanced Programmed Fuel Injection (PGM-FI) the TSX meets strict Tier 2-Bin 5, and Low Emission Vehicle-2 (LEV-2) standards.
The TSX is offered with either a 6-speed close-ratio manual transmission or a 5-speed SportShift automatic. The manual gearbox features a lightweight magnesium alloy case and multi-cone synchronizers. This transmission has a light, quick action and very short shift throws.
