From Acura press: Designed and engineered to reaffirm its place as a desirable and affordable entry point for the Acura sedan range, the all-new second-generation 2009 TSX is larger, more agile, more powerful and even "more Acura" than ever before. Carefully crafted to honor the original TSX's vision as a world-class sports sedan, the TSX has significantly evolved to offer more comfort, safety, convenience and driving performance - dramatically raising the standards for Acura's entry-level sedan.
With sharp-edged and athletic styling, a powerful, clean and efficient i-VTEC® 4-cylinder engine, a choice of automatic or manual transmission, and the kind of driving character that's an Acura trademark, the 2009 TSX continues as a valuable asset to the Acura division - and to a loyal following of customers. Major advances in handling agility, safety features, emissions reduction, ride smoothness and quietness, and interior comfort and convenience features all contribute to the new TSX's added appeal.
The new TSX's size, weight and total performance work in balance. The result is a car that is comfortable for five passengers, yet agile and responsive for performance driving. The same balanced thinking applies to the TSX powertrain. With an advanced in-line 4-cylinder powerplant, TSX offers strong acceleration, combined with low overall weight and compact packaging. Fuel efficiency is also a strong point.
An advanced, all-aluminum 2.4-liter DOHC i-VTEC® in-line 4-cylinder engine produces 201 hp and 172 pound-feet of torque (MT), and incorporates Acura's i-VTEC® "intelligent" valve control system that features Variable Valve Timing and Lift Electronic Control (VTEC®) combined with Variable Timing Control™ (VTC™). Though peak horsepower is virtually unchanged versus the previous generation engine, peak torque output has risen by 8 lb-ft. In addition, the engine's torque curve has fattened considerably. Horsepower, for example, is up five percent at 4,400 rpm. The result is stronger throttle response and better acceleration just about everywhere in the engine's operating range. To achieve these power gains, the engine has a higher compression ratio, new valve timing, and intake and exhaust flow improvements. A new aluminum and resin composite intake manifold reduces weight over the previous aluminum design, while better insulating the engine's incoming airflow from under-hood heat.
Though engine performance has improved, the powerplant delivers better fuel economy and has reduced emissions.
