The Acura TSX is an entry-level luxury car manufactured by Honda. Introduced in April 2003, it was sold only in the United States and Canada, but from the 2009 model year on it will also be available in Mexico. As of 2008, the TSX is the smallest vehicle in the Acura model line, other than the Civic-based CSX sold only in Canada. The TSX is badge engineered from the CL-series Accord (also known as the European Accord or JDM Accord) sold in Europe, Japan and Australia. In the Australian & New Zealand, the CL-series is sold Accord Euro, a smaller mid-size car, where the USDM Accord is sold in the large car category. In North American, the TSX is sold alongside the mid-size luxury Acura TL, which itself is based on the USDM Accord, as well as the USDM Accords sold under the Honda name. First generation (2004–2008) The 2008 model year TSX's powertrain was comprised of a 2.4-litre inline four-cylinder engine, a six-speed manual transmission and a front wheel drive layout. A five-speed automatic transmission was optional and did not incur extra cost in the U.S. based on MSRP. 2005 was the second year of the TSX and Acura updated it with XM Satellite Radio, heated door mirrors, a four-way power passenger seat and illuminated the steering wheel-mounted audio and cruise controls. 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. Engine The K24A2 engine used in the TSX was 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. Since 2006 model year, the Acura TSX has used a 2.4-litre in-line 4 cylinder engine making 205 hp (153 kW) SAE J1349 net. The advertised increased power figures on previous models were over-estimated by +10 hp (7 kW), the actual power rating is 205 hp (153 kW). SAE J1349 is a third party program designed to eliminate ambiguities that allowed engine makers to cite power and torque ratings higher than the engine's actual capabilities. Second generation (2009–) The fully redesigned 2009 Acura TSX made its debut at the 2008 New York International Auto Show on April 11, 2008. The new TSX uses a base engine similar to that of the 2008 TSX. The engine is a 2.4-litre in-line 4 cylinder engine reaching 201 hp (150 kW) and 172 lb-ft (233 N-m) torque. The transmission choices remain 5-speed automatic and 6-speed manual, though the automatic version now comes with steering-wheel paddle shifters for optional manual shifting. In addition to the 2.4-litre engine, the Acura TSX also receives Honda's 2.2-litre i-DTEC clean turbodiesel engine in the 2010 calendar year. The i-DTEC engine features an advanced NOx emissions reduction system that does not require urea additives to meet emissions standards in all 50 states. The 2009 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. 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.
