The Acura TSX is a compact executive car manufactured by Honda's luxury vehicle division, and was engineered from the CL-series Accord sold in Europe, Japan, South Africa, Australia, and New Zealand. Even though it was originally a European Honda Accord, the car still got the familiar Acura styling including the shield grille and other signature pieces. This sporty sedan was known to compete with the BMW 3-Series and Audi A4, as it did so much for a car smaller than the others in its category. The 2.4L four-cylinder engine adds perfect execution, making the TSX worthy to be pit against the BMW 325i. It filled the gap as Acura's four-door, entry-level luxury car when the Integra sedan was discontinued. The Acura TSX also eventually replaced the Acura RSX in the US.
First generation: 2004 to 2008
The first Acura TSX launch included Honda's 2.4-liter four-cylinder engine that was rated at 200 horsepower. It had a broad torque curve, immediately responding to the drive-by-wire throttle and quick work with its gearbox. Aside from the engine, the car's suspension was very close to that of a European sports sedan. Its brakes instantly reacted even when the car was at high speed, and the pedals can be effortlessly pushed for braking and downshifting. With these features, Acura TSX owners felt as if they owned a European car.
Even though the TSX was built from the European Accord platform, the sports car's interior was redesigned and the suspension tuning was set differently from that of the original. In 2008, its restyled interior became the standard for all three markets--US, Europe, and Japan.
Second generation: 2009 onwards
On April 2008, the redesigned 2009 Acura TSX made its debut as Honda's first diesel-powered car in the US when it was launched at the New York International Auto Show. The second-generation sedan offered two engine options--one being Honda's 2.2-liter diesel engine, and the other was the turbocharged four-cylinder engine used in the Acura RDX small SUV. One notable difference between the 2009 model from the previous one is its larger size. The second-generation TSX had a 3-inch greater width, a 2.6-inch wider track, and a 1.3-inch longer wheelbase; the car's overall length also grew by 2.4 inches. These expansions brought about the increase in curb weight by 100 to 150 lb.
An innovation that debuted with the 2009 Acura TSX was Honda's Advanced Compatibility Engineering body structure, which was designed to distribute collision energy evenly and redirect it away from the passenger compartment while minimizing damage to other impacted vehicles as well. In the years that followed, this structure had become a standard on all Honda and Acura models.
